Zebra rock is an ornamental stone from the early Ediacaran, Ranford Formation, around and in Lake Argyle, south of Kununurra, Western Australia. It has been regarded as a marine clay, liquid crystal, groundwater alteration, unconformity paleosol or product of acid sulfate weathering. This study supports the latter hypothesis and finds modern analogues for its distinctive red banding in mottling of gleyed soils. Other acid sulfate paleosols of desert playas (Gypsids) are also are found in the Ranford Formation, as well as calcareous desert paleosols (Calcids). The megafossil Palaeopaschnicnus also found in associated grey shales may have been a chambered protozoan, but Yangtziramulus in calcic paleosols is most like a microbial earth lichen. Soil climofunctions are evidence of an arid, cool temperate climate during the early Ediacaran.

Determination of dye biosorption capacity by lichen biosorbent and reusability of the waste lichen biosorbent as an antimicrobial agent are the aims of this study. The study has three stages: 1. to carry out dye biosorption assays, 2. to scan antimicrobial activity of waste lichen biosorbent after dye loaded, 3. to examine the antimicrobial function of a fabric which absorbed waste lichen extract. The optimal conditions for the best dye biosorption were determined. After the biosorption experiments, the waste lichen biomass was harvested from the working solution and the extraction of dye-loaded waste biomass was done using methanol and ethanol. The extracts obtained from both dye-loaded and un-loaded biosorbents were scanned for antimicrobial activity potential by the disk diffusion method. The results of this study showed that the waste lichen biosorbent of biosorption processes can be reused as antimicrobial agents.

The lichen species of Iraq are poorly known and no accurate checklist has been produced so far. Here we carried out an extensive review of existing literature and carried out additional field work to expand the knowledge of lichens in Iraq. We present the first checklist of lichens in Iraq which comprises a total of 236 species. The field survey identified four lichen species as new to Iraq. Although this checklist is not a full checklist of the lichens of Iraq it represents the most complete list to date. It is likely that increased sampling will lead to further new records of lichen species in Iraq. Keywords: checklist, Halabja province, Iraq, lichens, new records,

We analyzed the structure of foliicolous lichen communities in the northernmost lowland forest of the Neotropics, Los Tuxtlas Tropical Biology Station in Veracruz, Mexico, and its dependence on phorophyte and microclimate. Along a 420-m long transect with 15 equidistant sampling points, within a 10 m radius of each point, we sampled a total 137 phorophytes and 411 leaves. The phorophytes represented 13 species, with diverse leaf traits regarding size, texture, presence of hairs and/or glands, and longevity, including: Astrocaryum mexicanum (Arecaceae), Chamaedorea ernesti-augustii (Arecaceae), Costus scaber (Costaceae), Guarea glabra (Meliaceae), Heliconia latispatha (Heliconiaceae), Monstera acuminata (Araceae), Myriocarpa longipes (Urticaceae), Piper hispidum (Piperaceae), Poulsenia armata (Moraceae), Pseudolmedia oxyphyllaria (Moraceae), Salacia megistophylla (Celastraceae), Siparuna thecaphora (Siparunaceae) and Syngonium podophyllum (Araceae). NDMS ordination and cluster analysis grouped the phorophytes into hierarchically structured clusters variously correlated with microsite, phorophyte species and foliicolous lichen species richness. Indicator species analysis revealed statistically significant foliicolous lichen species characteristic for terminal clusters and for phorophyte species. We conclude that the principle of “diversity begets diversity” may apply, in that phorophyte diversity influences the diversity of foliicolous lichen communities through the manifestation of subtle phorophyte preferences, best seen in well-developed communities on leaves with higher longevity. Thus, wellpreserved forest ecosystems, with a higher diversity of suitable phorophytes, will support a higher diversity of foliicolous lichens, a phenomenon that extents to epiphytes in general. Keywords: biodiversity maintenance, environmental monitoring, epiphyte diversity, phyllosphere, tropical rainforest.

The national park of El Kala is caracterised with an exceptional lichen flora, taking in to account the diversity of the phorophytes. Three sites have made the object of our study: Lake Tonga, Lake Oubeïra and Lake Mellah. The associations with Quercetum suberis being the most representative in the round of wetlands, where we studied the lichen flora on Quercus suber and making systematic surveys on 2 m high for four faces of the substrate. Moreover, a number of data on environmental conditions of the stations studied was considered and thus allowed us to appreciate the importance of specific lichen biodiversity in defined micro-climatic conditions. We have examined the influence of phorophyte diameter on the lichen cover and with respect to inter-category competitions observed during the statistical analysis. Our survey of epiphytic lichens in the cork forests of the wetlands of El Kala National Park was a success. From a systematics point of view, with 25 families comprising 135 catalogued species, we can certainly say that the region supports a wide variety of lichens. Most of the lichen taxa are essentially from the Parmeliaceae family, principally represented by the genus Parmelia, and from the Physciaceae family, represented by the genera Physcia and Physconia recognized by their nitrophilous species. From a morphological point of view, the catalogued taxa are divided into 69 crustose species, 37 foliose species, 15 fruticose species, 9 gelatinous species, 4 compound species and 1 squamulose species. Keywords: Lichens, Quercus suber, Wetlands, El Kala National Park, North-Eastern Algeria.

The study of the lichenic flora on Quercus coccifera carried out in the region of El Kala which is in the extreme Northeast Algeria proved very interesting. More than 50 lichens were recorded represented by two types of photobionts; green algae and Trentepohlia. The systematic spectrum indicates that the listed lichens belong to 14 families, the most important of which are the Parmeliaceae and the Physciaceae. The physiognomic spectrum notes the presence of only 3 lichenic categories: crustaceans, foliaceae and fruit. The total wealth quantified by type of vegetation stage mentions the importance of the lichens of the thermomediterranean stage with 50%. The ecological index relating to the phytogeographical aspect indicates that the lichenic flora of the phorophyte studied consists of two main chorotypes; the temperate and the suboceanic.

Information about lichen diversity in Algeria is limited despite their important role as biological indicators of ecosystem health. The aim of the study was to carry out an inventory of epiphytic lichens in the Mount Babor Forest on two types of phorophytes (host trees), i.e., Cedrus atlantica and Quercus faginea, in varying altitudinal gradients and the diameter of host tree. The similarity of the sampled sites was assessed by the Sorensen index (?). Sixty-six species of epiphytic lichens were identified, which belong to 24 families and 38 genera. C. atlantica hosted a higher number of species than Q. faginea. The majority of lichen on C. atlantica belonged to the Parmeliaceae family, whereas those on Q. faginea belonged to the Physciaceae family. Crustose and foliose lichens were the most common species in the study area. The results showed the existence of a distinct relationship between the parameters of the distribution (i.e., tree diameter, elevation) and the specific lichen richness. The greatest number of lichen species (59 species) was observed on large diameter trunks (41-60 cm). Lichen diversity increased along with the increase in altitude. Sorensen’s similarity index revealed the presence of heterogeneity in the community composition of lichen vegetation. Keywords: Algeria, biodiversity, Cedrus atlantica, epiphytic lichens, Mount Babor Forest, Quercus faginea.

Lichens from an unusually large, arborescent runner oak (Quercus pumila) from Miami-Dade County, Florida, were collected and inventoried. A total of 56 lichen species and one lichenicolous lichen species were found, representing 17 families with Graphidaceae bearing the most (14) species. Several species recorded were also recently reported or newly described from South Florida, which has a tropical climate and ecoregion that are distinct in the continental United States. Some lichen species (especially crustose Arthoniaceae and Graphidaceae) are twig specialists not normally found on trunks and branches; therefore, future studies of lichen diversity on single trees should include as much twig material as possible.

Common reed (Phragmites) interacts with a large suite of other organisms including cryptogams attached to live or dead culm bases. We report an unusual observation of at least ten taxa of lichens and hepatics attached to persistent reed stubble on the swampy bank of freshwater Cypress Creek north of Tampa, Hillsborough County, Florida. This bryoid material included the minute, leafy hepatics Microlejeunea globosa, Microlejeunea cf. ulicina, Myriocoleopsis minutissima, and Frullania cf. inflata; and the lichens Arthonia subdiffusa, Chrysothrix xanthina, Opegrapha viridis, Phaeographis sp., Physcia sp., and an unidentified species of Parmeliaceae. These generally corticolous or epiphyllous taxa have not previously been reported from common reed, and suggest unrecognized complexity in both cryptogamic microhabitats and reed epiphytes.

The dominance of aeolian processes in arid areas created a harsh environment in these regions for soil and vegetation where soil fertility, ecosystem productivity, air clarity, and human health is dependent to aeolian activities and rate of dust emission. Biological soil crusts (bio-crusts) are the communities of living organisms on the soil surface which play an important role in soil ecosystem services in arid land. Lichens are known as organisms that can accumulate certain elements or substances at high concentrations in the atmosphere. The relation between lichens species and soil geochemistry as well as dust capture in geomorphic zones in northeastern Iran were studied. Different lichens species and soil particles were analyzed by a scanning electron microscopy (SEM-EDS). The results of XRF and XRD analysis showed lichen crusts affected soil mineralisation. By creating microtopography, indicated the lichens trapped dust. They also increased the amount of clay on the soil surface. The results indicted the significant role of lichens in soil ecosystem services dryland. Keywords: Geochemistry; Granulometry; Lichen crusts; Mineralogy; Soil erosion; Dryland.

Vascular and nonvascular plants are affected by environmental factors determining their distribution and shaping their diversity and cover. Despite the cryptogam commonness in Arctic communities, previous studies have often focused on limited number of factors and their impact on only selected species of vascular plants or cryptogams. Our study aimed to investigate in detail the differences in species diversity and cover of cryptogams and vascular plants in the glacier forelands and mature tundra on Svalbard. Furthermore, we determined the biotic and abiotic factors that affected diversity, cover and distribution of cryptogam and vascular plant species. In 2017, we established 201 plots in eight locations (each including habitat type of foreland and mature tundra) and surveyed species abundance, sampled soils and environmental data. Results revealed that diversity and cover of analysed groups differed significantly between locations and habitat types, except for cryptogam cover in mature tundra in terms of location. Distance to the glacier terminus, slope, soil conductivity, nutrient content, and clay content impacted both plant groups' diversity. In contrast, distance to the glacier terminus, nutrient content and soil pH affected their cover. In addition, for cryptogam diversity and cover, foreland location and vascular plant cover were also important, while for vascular plant cover time elapsed after glacier retreat was significant. Distribution of both groups' species in forelands was associated with time elapsed after glacier retreat, soil pH, and nutrient contents. Soil texture and distance to the glacier terminus additionally influenced cryptogam distribution. The positive impact of vascular plants on cryptogam diversity and cover indicates complex relationships between these groups, even in forelands' relatively simple communities. As the cryptogam diversity in the polar areas is high but still largely unknown, future studies on species ecology and climate change impact on vegetation should consider both vascular plants and cryptogams and interactions between these groups.

Dimorphism is a widespread feature of tremellalean fungi in general, but a little-studied aspect of the biology of lichen-associated Tremella. We show that Tremella macrobasidiata and Tremella variae have an abundant and widespread yeast stage in their life cycles that occurs in Lecanora lichens. Their sexual filamentous stage is restricted to a specific lichen: T. macrobasidiata only forms basidiomata on Lecanora chlarotera hymenia and T. variae only on Lecanora varia thalli. However, the yeast stage of T. macrobasidiata is less specific and can occur in L. varia lichens, whilst all life stages of T. variae may be specific to L. varia. Contrary to the hyphal stages, the yeasts are distributed across the thalli and hymenia of Lecanora lichens, and not limited to specimens with basidiomata. Tremella macrobasidiata was present in all studied L. chlarotera, and in 59% of L. varia specimens. Only in 8% of the L. varia thalli could none of the two Tremella species be detected. Our results indicate that lichen-associated Tremella may be much more abundant and widespread than previously assumed leading to skewed estimations about their distribution ranges and lichen specificity, and raise new questions about their biology, ekology and function in the symbiosis.

Gaseous phase hydration properties for thalli of Niebla tigrina from Atacama Desert, and for Umbilicaria antarctica from Isla Robert, maritime Antarctica, were analyzed using 1H-NMR relaxometry, spectroscopy, and sorption isotherm analysis. The molecular dynamics of residual water was monitored to distinguish the sequential binding very tightly, tightly, and loosely bound water fractions. These two species differ in hydration kinetics faster for Desert N. tigrina [A1 = 0.51(4); t1 = 0.51(5) h, t2 = 15.0(1.9) h; total 0.7 for p/p0 = 100%], compared to Antarctic U. antarctica [A1 = 0.082(6), t1 = 2.4(2) h, t2 = [26.9(2.7)] h, total 0.6 for p/p0 = 100%] from humid polar area. The 1H-NMR measurements distinguish signal from tightly bound water, and two signals from loosely bound water, with different chemical shifts higher for U. antarctica than for N. tigrina. Both lichen species contain different amounts of water-soluble solid fraction. For U. antarctica, the saturation concentration of water soluble solid fraction, cs = 0.55(9), and the dissolution effect is detected at least up to Δm/m0 = 0.7, whereas for N. tigrina with the similar saturation concentration, cs = 053(4), this fraction is detected up to the threshold hydration level equal to ΔM/m0 = 0.3 only.

During a three-day field trip to the Gaupne area, Luster kommune, three main localities were visited in search of lichens. A total of 35 lichens or lichenicolous fungi were found to be new to Sogn og Fjordane, most of which are also rare on a national scale. Three species on rocks, Calogaya biatorina, Lecanora gislerianaand L. subaurea, are red-listed and two species, Blastenia monticolaand Caloplaca squamuleoisidiata, are new to Norway. Most of the species new to Sogn og Fjordane are calcicolous or prefer siliceous rocks containing high levels of heavy metals. The area around Gaupne is shown to be a previously unknown lichen hot-spot.

It is now a decade since The International Commission on the Taxonomy of Fungi (ICTF) produced an overview of requirements and best practices for describing a new fungal species. In the meantime the International Code of Nomenclature for algae, fungi, and plants (ICNafp) has changed from its former name (the International Code of Botanical Nomenclature) and introduced new formal requirements for valid publication of species scientific names, including the separation of provisions specific to Fungi and organisms treated as fungi in a new Chapter F. Equally transformative have been changes in the data collection, data dissemination, and analytical tools available to mycologists. This paper provides an updated and expanded discussion of current publication requirements along with best practices for the description of new fungal species and publication of new names and for improving accessibility of their associated metadata that have developed over the last 10 years. Additionally, we provide: (1) model papers for different fungal groups and circumstances; (2) a checklist to simplify meeting (i) the requirements of the ICNafp to ensure the effective, valid and legitimate publication of names of new taxa, and (ii) minimally accepted standards for description; and, (3) templates for preparing standardized species descriptions. Keywords: Data repositories, Dual nomenclature, FAIR principles, Legitimate publication, New combinations, Taxonomic best practices, Typification, Valid publication.

Phylogenetic reconstructions based on ITS/5.8S, mtSSU and nuLSU DNA sequence data suggest that Lecanora pringlei from North America and a closely related new species from the Altai Mountains, Russia, should be transferred to a new genus Pulvinora, phylogenetically related to Frutidella. It is distinguished by Lecanora-type asci, mycolecanorine apothecia soon becoming convex with an algal layer pushed below the hypothecium, and a pulvinate thallus with squamules at the tip of pseudopodetialike, branched, pale brownish structures. Lecanora subcavicola and L. pringlei subsp. brandegeei do not belong to this new genus Pulvinora; consequently, we propose the new combination L. brandegeei to accommodate the latter taxon. Pulvinora stereothallina is distinguished from P. pringlei in the shape and size of its squamules (plane to concave, up to 3.0 mm long vs. remaining convex, up to 1.5 mm long), by the lack of maculae, the presence of a whitish pruina on the margins and elevated parts of its squamules, by apothecia coalescing into clusters (vs. single), an ochre-yellow to brownish (vs. colorless) proper exciple, larger ascospores, and different secondary metabolites. Lectotypes of Lecidea pringlei Tuck. and L. brandegeei Tuck. are designated here from the collections deposited in FH.

Lichens represent a significant source of antioxidants due to numerous metabolites that can reduce free radicals. Usnea barbata (L.) F.H. Wigg. has been recognized and used since ancient times for its therapeutic effects, some of which are based on its antioxidant properties. The present study aims to analyze the phytochemical profile and to evaluate the antioxidant and cytotoxic potential of this lichen species. Five dry extracts of U. barbata (UBDE) in different solvents (acetone, ethyl acetate, ethanol, methanol, water) were prepared by refluxing at Soxhlet to achieve these proposed objectives and to identify which solvent is the most effective for the extraction. The usnic acid content (UAC) was quantified by ultra-high performance liquid chromatography (UHPLC). The total polyphenols content (TPC) and tannins content (TC) were evaluated by spectrophotometry, and the total polysaccharides (PSC) were extracted by a gravimetric method. The 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) free radical method was used to assess the antioxidant activity (AA) and the Brine Shrimp Lethality (BSL) assay was the biotest for cytotoxic activity evaluation. The ethyl acetate extract had the highest usnic acid content, and acetone extract had the highest content of total polyphenols and tannins. The most significant antioxidant effect was reported to methanol extract, and all the extracts proved high cytotoxicity. The water extract has the lowest cytotoxicity because usnic acid is slightly soluble in this solvent, and it was not found at UHPLC analysis. All extracts recorded a moderate correlation between the content of usnic acid, polyphenols, tannins, and AA; furthermore, it has been observed that the cytotoxicity varies inversely with the antioxidant effect. Keywords: U. barbata; usnic acid; UHPLC; polyphenols; tannins; polysaccharides.

Permafrost thaw in continental lowlands produces large number of thermokarst (thaw) lakes, which act as a major regulator of carbon (C) storage in sediments and C emission in the atmosphere. Here we studied thaw lakes of the NE European permafrost peatlands - shallow water bodies located within frozen peat bogs and receiving the majority of their water input fromlateral (surface) runoff.Wealso conductedmesocosm experiments via interacting lake waters with frozen peat and dominant ground vegetation - lichen and moss. There was a systematic decrease in concentrations of dissolved C, CO2, nutrients and metals with an increase in lake size, corresponding to temporal evolution of the water body and thermokarst development.We hypothesized that ground vegetation and frozen peat provide the majority of C, nutrients and inorganic solutes in thewater columnof these lakes, and that microbial processing of terrestrial organic matter controls the pattern of CO2 and nutrient concentrations in thermokarst lakes. Substrate mass-normalized C, nutrient (N, P, K), major and trace metal releasewas maximal in moss mesocosms. After first 16 h of reaction, the pCO2 increased ten-fold in mesocosms with moss and lichen; this increase was much less pronounced in experiments with permafrost peat. Overall, moss and lichen were the dominant factors controlling the enrichment of the lake water in organic C, nutrients, and trace metals and rising the CO2 concentration. The global significance of obtained results is that the changes in ground vegetation, rather than mere frozen peat thawing, may exert the primary control on C, major and trace element balance in aquatic ecosystems of tundra peatlands under climate warming scenario.

Here we report the effects of atranorin (ATR), gyrophoric acid (GPA), and thamnolic acid (TMA) on the physiological, biochemical, and cytological characteristics of Allium fistulosum L. seedlings for the first time. Of the lichen substances investigated, ATR and TAM had the highest phytotoxicity effects. ATR (4000 - 1000 μM) and TAM (4000 μM) inhibited the growth processes and increased the intensity of lipid peroxidation in A. fistulosum, and as a result the activities of the protective enzymes peroxidase, catalase, and superoxide dismutase increased, and the contents of photosynthetic pigments in the A. fistulosum seedlings decreased. ATR at concentrations 2000 and 4000 μM caused decrease of mitotic activity and increase of chromosomal aberrations frequency in root cells. The weakest phytotoxic properties were shown by GPA, which caused no changes in the physiological, cytological, or biochemical parameters of the A. fistulosum seedlings across the entire range of concentrations tested. Keywords: Allium fistulosum; Phytotoxicity; Atranorin; Thamnolic acid; Gyrophoric acid.

The fascinating world of lichens draws the attention of the researchers because of the numerous properties of lichens used traditionally and, in modern times, as a raw material for medicines and in the perfumery industry, for food and spices, for fodder, as dyes, and for other various purposes all over the world. However, lichens being widespread symbiotic entities between fungi and photosynthetic partners may acquire toxic features due to either the fungi, algae, or cyano-procaryotes producing toxins. By this way, several common lichens acquire toxic features. In this survey, recent data about the ecology, phytogenetics, and biology of some lichens with respect to the associated toxin-producing cyanoprokaryotes in different habitats around the world are discussed. Special attention is paid to the common toxins, called microcystin and nodularin, produced mainly by the Nostoc species. The effective application of a series of modern research methods to approach the issue of lichen toxicity as contributed by the cyanophotobiont partner is emphasized. Keywords: toxic lichens; toxic cyanoprokaryotes; lichen toxins.

The identification and proper naming of microfungi, in particular plant, animal and human pathogens, remains challenging. Molecular identification is becoming the default approach for many fungal groups, and environmental metabarcoding is contributing an increasing amount of sequence data documenting fungal diversity on a global scale. This includes lineages represented only by sequence data. At present, these taxa cannot be formally described under the current nomenclature rules. By considering approaches used in bacterial taxonomy, we propose solutions for the nomenclature of taxa known only from sequences to facilitate consistent reporting and communication in the literature and public sequence repositories.

Lichen species diversity and trend of their distribution were studied in two big cities and five towns in south-east of Western Siberia. In total of 348 species from 46 families and 98 genera were found in all studied urban and suburban areas. All local checklists are characterized by high degree of the lichen species similarity between each other and smaller lists are included in bigger ones on to 64-100%. Epiphytic lichens were the largest group in all studied areas and almost half of them were occupied two and more substrates. Crustose life-form and mesophytes prevailed everywhere. Share of sensitive lichens exceeded percent of tolerant ones in big cities and was lower than tolerant ones in smaller towns. The sixteen species were the most tolerant, commonly present everywhere and have been recognized as the key species for urban lichen synusiae within south-east of Western Siberia. Five zones have been determined with IP-mapping (mapping on the base of index of air pollution tolerance) in studied areas: IP=3-5 is a “normal zone”, IP=5-7 is a “moderate exposure zone”, IP=7-9 is a “mixed zone”, IP=9-10 is a “struggle zone”, and finally – lichen-free zone. The most studied urban areas had got quite extensive lichen-free zone (up to 35% of their areas). Key words: lichens, synusiae, IP-mapping, Western Siberia, urban areas.

[in Italian with English abstract: ] The Maremma Natural History Museum is active in the field of Citizen Science at the Tuscan, national and international level. Among the founding bodies of the European Citizen Science Association (ECSA), it has promoted meetings for a national Citizen Science strategy in Italy, actively participated in the drafting of national guidelines on the subject and developed Citizen Science projects in Tuscany and other regions nearby. BioBlitzes are one of the best-known activities in the field of environmental Citizen Science. In May 2016, the Museum organized its fourth BioBlitz at the Accesa Lake Special Protection Area. On this occasion, data collected attested the presence of 784 different taxonomic entities, 678 of which were identified at the species level and 18 at the subspecies level. Nineteen alien species and two endemic species have been identified. Thirty-nine species protected by national or international laws and 13 endangered species have been detected. The area has been confirmed to be an important biodiversity hotspot; future utilization plans must be developed with due consideration for the fragility of the habitats close to the lake from the conservation point of view.

Digital photogrammetry was used to measure growth rates and track changes at the margins of marked Rhizocarpon geographicum agg. thalli on quartzite at the Illecillewaet Glacier in western Canada. The decadal rates were used to validate a lichenometric “growth curve” calibrated using the five largest thalli on historically and tree-ring dated surfaces. Macro-photographs of lichens were orthocorrected by ‘Structure from Motion’ (SfM) techniques to create a 20 yr image timeline. Model resolution was high (0.01 to 0.03 mm pix), photo alignment was accurate (mean relative error < 1.4%) and measurements were validated. Mean areal growth in 59 thalli was highly variable ( x¯ = 9.43 mm2 yr−1 for 1996–2006; and 7.72 mm2 yr−1 for 2006–2016). Tiny thalli (<5 mm long axis) had jagged outlines and slow irregular growth (0 to 0.2 mm yr−1). Long axis growth in the five fastest of 45 thalli (>5 mm long axis) with circular outlines was 0.5 to 0.92 mm yr−1 and mean annual radial growth on four radii per thallus was 0.23 to 0.31 mm yr−1. Several thalli kept a nearly circular shape even after fusing with others. Extrapolated mean radial growth of the fastest thallus in either decade closely predicted the largest and five thallus sizes on historically dated surfaces (−5.43 mm difference at 53 yr, <1.75 mm at 75 to 101 yr). This is an error of about one year at 75 to 101 yr. The findings validate indirectly calibrated rates and surface ages at this site and challenge key assumptions and claims made by proponents of lichenometric dating. Keywords: Lichenometric dating; Lichenometry; Rhizocarpon geographicum; Lichen growth; Structure-from-motion (SfM); Close-range photogrammetry.

Over the last few years, the emergence and widespread distribution of microbial resistance to antibiotics is world-wide challenge in the medical science. In this regard, lichens are one promising antimicrobial agent which could be replaced by traditional antibiotics due broad-spectrum with potent antimicrobial activity. In this study, the ZnO/GQDs nanocomposites (NCs) and Protoparmeliopsis muralis extract-grafted ZnO/GQDs NCs have been prepared via green method. The prepared products are characterized with XRD analysis, SEM and FTIR. Interestingly, the linking of Protoparmeliopsis muralis extract into ZnO/GQDs NCs demonstrated strong antibacterial activity with to 5-log reduction in bacterial CFU/ml compared to P. muralis for at 4 days. Additionally, the nanocarrier demonstrated to 88 and 83% inhibition of biofilm formation when tested against methicillin resistant Staphylococcus aureus (MRSA) and vancomycin resistant Enterococcus faecalis (VRE) respectively. Finally, results this study reported that the use of the P. muralis/ZnO/GQDs–NCs formulation could be employed as a novel agent antibacterial to inhibit bacterial growth and the biofilm formation.

Spatial variation of the levels of polycyclic aromatic hydrocarbons (PAHs) was evaluated within an urbanindustrial district where the main anthropogenic pressures are a 15MW biomass power plant (BPP) and road traffic. The use of a high-density lichen transplant network and wind quantitative relationships made it possible to perform a hierarchical analysis of contamination. Combined uni-bi and multivariate statistical analyses of the resulting databases revealed a dual pattern. In its surroundings (local scale), the BPP affected the bioaccumulation of fluoranthene, pyrene and total PAHs, although a confounding effect of traffic (mostly petrol/gasoline engines) was evident. Spatial variation of the rate of diesel vehicles showed a significant association with that of acenaphthylene, acenaphthene, fluorene, anthracene and naphthalene. The series of high-speed wind values suggests that wind promotes diffusion rather than dispersion of the monitored PAHs. At the whole study area scale, the BPP was a source of acenaphthylene and acenaphthene, while diesel vehicles were a source of acenaphthylene. PAHs contamination strongly promotes oxidative stress (a threefold increase vs pre-exposure levels) in lichen transplants, suggesting a marked polluting effect of anthropogenic sources especially at the expense of the mycobiont. The proposed monitoring approach could improve the apportionment of the different contributions of point and linear anthropogenic sources of PAHs, mitigating the reciprocal biases affecting their spatial patterns. Keywords: PAHs; Biomass power plant; Lichen transplants; Wind quantitative relationships.

Spatial patchiness in resources is a pervasive feature of drylands worldwide. This patchiness manifests itself as two distinct geomorphic zones that are characterised by the loss (runoff) or gain (runon) of resources such as water, seed and organic matter. Most studies have examined how vascular plants vary across these two distinct zones, but there are few studies of the non-vascular components of these patterned landscapes. We examined the distribution of soil crust lichens and bryophytes (moss, liverworts) in relation to three geomorphic positions within a patterned Acacia aneura woodland grazed by sheep and kangaroos. We found that the distribution of biocrust taxa was strongly related to geomorphic position, with lichens dominating the runoff zones and liverworts restricted to the runon areas (groves). The runon zones were characterised by a greater cover of litter, and greater species richness, cover, and functional richness of biocrusts, while biocrusts in the runoff zones had greater functional diversity and dispersion. Importantly, biocrusts growing in the runon areas were taller, had shorter rhizines, and a greater capacity to trap sediment and absorb water. There were no effects of grazing intensity nor herbivore type (sheep cf. kangaroo) on any diversity or functional measures of biocrusts. Overall, our study indicates that the functional attributes of biocrusts align with those reported for vascular plants (e.g., perennial grasses), by affecting hydrological processes and sediment capture, albeit at smaller spatial scales. Biocrusts may be important, therefore, for sequestering small falls of water emanating from resource-shedding zones, thereby reinforcing landscape patchiness, particularly as hotter and drier climates reduce the cover of vascular plants in drylands.

Anthropogenic nitrogen (N) and sulfur (S) deposition can negatively affect ecosystem functions and lichen biomonitors can be a cost-effective way to monitor air pollution exposure across the landscape. Interior dry forests of the southwestern United States face increasing development pressures; however, this region differs from others with well-developed biomonitoring programs in having drier climates and a greater fraction of deposition delivered in dry forms. We measured throughfall N and S deposition at 12 sites in Utah and 10 in New Mexico and co-located collection of 6 lichen species. Throughfall N deposition ranged from 0.76 to 6.96 kg/ha/ year and S deposition from 0.57 to 1.44 kg/ha/year with elevated levels near human development that were not predicted by commonly used simulation models. Throughfall N was 4.6 and 1.6 times higher in summer compared with fall-spring in Utah and New Mexico and S deposition was 3.9 and 1.8 times higher in summer. Lichen N and S concentrations ranged from 0.97 to 2.7% and 0.09 to 0.33%. Replicate samples within plots showed high variability in N and S concentrations with within-plot coefficients of variation for N ranging between 5 and 10% and for S between 7 and 15%. In Utah, N and S concentrations in lichen species were correlated with each other in most cases, with R2 ranging from 0.52 to 0.85. N concentrations in Melanohalea exasperatula and Melanohalea subolivacea could be correlated with average annual throughfall N deposition in Utah (R2 = 0.58 and 0.31). Those relationships were improved by focusing on deposition in fall-spring prior to lichen sampling in Utah (R2 for M. exasperatula, M. subolivacea, and X. montana = 0.59, 0.42, and 0.28). In New Mexico, lichens exhibited greater coefficients of variability within plots than between plots and could not be correlated with throughfall N deposition. In neither study area was S correlated between lichens and throughfall deposition, which may be the result of low S deposition over a narrow deposition range or complex lichen assimilation of S. Lichen biomonitoring for N deposition in the region shows promise, but could potentially be improved by sampling more thalli to reduce within-plot variability, repeated lichen collection synchronized with throughfall changeouts to explore temporal variability, and washing lichen collections to distinguish N and S that has been incorporated by the thalli from dry deposition that may accumulate on lichen surfaces. Key words: Energy development; Lichen; Seasonal deposition; Throughfall; TDep; CMAQ; Ion exchange resin samplers.

(2021): The bacterial community of the foliose macro-lichen Peltigera frigida is more than a mere extension of the microbiota of the subjacent substrate. - Microbial Ecology, 81: 965–976. https://doi.org/10.1007/s00248-020-01662-y.|
Lichens host highly diverse microbial communities, with bacteria being one of the most explored groups in terms of their diversity and functioning. These bacteria could partly originate from symbiotic propagules developed by many lichens and, perhaps more commonly and depending on environmental conditions, from different sources of the surroundings. Using the narrowly distributed species Peltigera frigida as an object of study, we propose that bacterial communities in these lichens are different from those in their subjacent substrates, even if some taxa might be shared. Ten terricolous P. frigida lichens and their substrates were sampled from forested sites in the Coyhaique National Reserve, located in an understudied region in Chile. The mycobiont identity was confirmed using partial 28S and ITS sequences. Besides, 16S fragments revealed that mycobionts were associated with the same cyanobacterial haplotype. From both lichens and substrates, Illumina 16S amplicon sequencing was performed using primers that exclude cyanobacteria. In lichens, Proteobacteria was the most abundant phylum (37%), whereas soil substrates were dominated by Acidobacteriota (39%). At lower taxonomic levels, several bacterial groups differed in relative abundance among P. frigida lichens and their substrates, some of them being highly abundant in lichens but almost absent in substrates, like Sphingomonas (8% vs 0.2%), and others enriched in lichens, as an unassigned genus of Chitinophagaceae (10% vs 2%). These results reinforce the idea that lichens would carry some components of their microbiome when propagating, but they also could acquire part of their bacterial community from the substrates.

Since lichens have been recognised as a potential natural source of bioactive substances, the aim of this study was to investigate the antimicrobial, lysozyme and antifungal effects of methanol, acetone and quencher extracts from four lichens: Diploschistes ocellatus, Flavoparmelia caperata, Squamarina cartilaginea and Xanthoria parietina. The results showed that the tested extracts had antimicrobial activity against Gram-positive and Gram-negative bacteria and anti-candida, and inhibit the spore germination of tested fungi. The different extracts varied in their effect as determined by the diameter of the inhibition zone, the highest values being observed with the methanol and acetone extracts (29.5 and 27.5 mm, respectively) for S. cartilaginea against Enterococcus faecalis. For powdered material (quencher), F. caperata showed the highest inhibition diameter (25.5 mm) against Staphylococcus aureus. The Minimum Inhibitory Concentration (MIC) values varied from 125 to 2000 μg mL−1. Methanol extracts of S. cartilaginea were more active against Enterobacter cloacae (MIC 125 μg mL−1) and Staphylococcus aureus (MIC 125 μg mL−1), and also affected lysozyme activity against Staphylococcus aureus, as well as the morphology of fungal hyphae. This study demonstrated that the investigated species are a potential source of bioactive compounds which are potentially important antimicrobial agents.

Lichens are the symbiotic association between photobiont algae and mycobiont fungi having diverse phytochemicals. However, they are still an underexplored natural resource for biological activities. In the present report, we have evaluated the anti-brain and anti-cervical cancer activity of tropical lichen, Dirinaria consimilis (DCME) through the cell viability assay, cell cycle analysis, annexin V-FLUOS staining, morphological analysis, ROS-induction mechanism, evaluation of antioxidant levels, and western blotting study. The WST-1-based cell viability assay showed the cytotoxic nature of DCME towards U87 (IC50-52.65 ± 1.04 µg/ml) and HeLa (IC50-77.60 ± 2.23 µg/ml) cells. Interestingly, DCME does not showed any toxicity towards non-malignant fibroblast cell line WI-38 (IC50-685.80 ± 19.51 µg/ml). Furthermore, the cell cycle analysis showed sub-G1 arrest (apoptosis), and annexin V-FLUOS staining showed an increase in early apoptosis population dose-dependently. Confocal-based morphological data confirmed the DNA condensation and fragmentation upon treatment. Furthermore, DCME treatment induces ROS and regulates the levels of antioxidant enzymes (SOD, Catalase, GST, and GSH) in both U87 and HeLa cells. Finally, the western blotting data revealed the increase in Bax/Bcl-2 ratio, activation of Bid, Caspase-8, -9 and -3 along with degradation of PARP. Moreover, regulation of MAP kinases and activation of p53 was also observed upon DCME treatment. Herein, we first reported the anticancer activity of D. consimilis against brain and cervical cancer cells. Performed in-depth anticancer study revealed the ROS-mediated regulation of MAP kinases and activation of caspase cascade in U87 and HeLa cells upon DCME treatment.

(2021): Predicting patterns of terrestrial lichen biomass recovery following boreal wildfires. - Ecosphere, 12(4): e03481 [25 p.]. https://doi.org/10.1002/ecs2.3481.|
Increased fire activity due to climate change may impact the successional dynamics of boreal forests, with important consequences for caribou habitat. Early successional forests have been shown to support lower quantities of caribou forage lichens, but geographic variation in, and controls on, the rates of lichen recovery has been largely unexplored. In this study, we sampled across a broad region in northwestern Canada to compare lichen biomass accumulation in ecoprovinces, including the Saskatchewan Boreal Shield, the Northwest Territories Taiga Shield, and Northwest Territories Taiga Plains, divided into North and South. We focused on the most valuable Cladonia species for boreal and barren-ground caribou: Cladonia mitis and C. arbuscula, C. rangiferina and C. stygia, and C. stellaris and C. uncialis. We developed new allometric equations to estimate lichen biomass from field measurements of lichen cover and height; allometries were consistent among ecoprovinces, suggesting generalizability. We then used estimates of lichen biomass to quantify patterns of lichen recovery in different stand types, ecoprovinces, and with time following stand-replacing fire. We used a hurdle model to account both for the heterogeneous nature of lichen presence (zero inflation) and for the range of abundance in stands where lichen was present. The first component of the hurdle model, a generalized linear model, identified stand age, stand type, and ecoprovince as significant predictors of lichen presence.With a logistic growth model, a measure of lichen recovery (time to 50% asymptotic value) varied from 28 to 73 yr, dependent on stand type and ecoprovince. The combined predictions of the hurdle model suggest the most rapid recovery of lichen biomass across our study region occurred in jack pine in the Boreal Shield (30 yr), while stands located in the Taiga Plains (North and South) required a longer recovery period (approximately 75 yr). These results provide a basis for estimating future caribou habitat that encompasses some of the large variation in fire effects on lichen abundance and vegetation types across the range of boreal and barren-ground caribou in North America.

The results of our in silico work were justified by in vitro studies, which showed potent dual cholinesterase inhibition. The lichen compound Zeorin showed promising neuroprotective potential via antioxidation, AChE inhibition and cytoprotective activity against H2O2-induced toxicity in mouse Neuroblastoma (N2a) cell line. Our results indicate that Zeorin, being a natural resource is a better choice of treatment for AD as it exhibits significant neuroprotection. However, exhaustive studies are needed to provide sufficient insights on the mechanism/path-way of lichen compound Zeorin in neuroprotection ability.

Endolichenic fungi (ELF) are emerging novel bioresources because their diverse second‐ ary metabolites have a wide range of biological activities. Metagenomic analysis of lichen thalli demonstrated that the conventional isolation method of ELF covers a very limited range of ELF, and the development of an advanced isolation method is needed. The influence of four variables were investigated in this study to determine the suitable conditions for the isolation of more diverse ELF from a radially growing foliose lichen, Parmotrema tinctorum. Four variables were tested: age of the thallus, severity of surface‐sterilization of the thallus, size of a thallus fragment for the inoculation, and nutrient requirement. In total, 104 species (1885 strains) of ELF were isolated from the five in‐ dividual thalli of P. tinctorum collected at five different places. Most of the ELF isolates belong to Sordariomycetes. Because each part of lichen thallus (of different age) has unique ELF species, the whole thallus of the foliose lichen is needed to isolate diverse ELF. Moderate sterilization is appro‐ priate for the isolation of diverse ELF. Inoculation of small fragment (1 mm2) of lichen thallus re‐ sulted in the isolation of highest diversity of ELF species compared to larger fragments (100 and 25 mm2). Moreover, ELF species isolated from the small thallus fragments covered all ELF taxa de‐ tected from the medium and the large fragments in this study. The use of two media—Bold’s basal medium (nutrient poor) and potato dextrose agar (nutrient rich)—supported the isolation of diverse ELF. Among the tested variables, size of thallus fragment more significantly influenced the isolation of diverse ELF than other three factors. Species composition and richness of ELF communities from different lichen thalli differed from each other in this study. Keywords: diversity; endolichenic fungi; foliose lichen; isolation method.

Lichens are classified into different functional groups depending on their ecological and physiological response to a given environmental stressor. However, knowledge on lichen response to the synergistic effect of multiple environmental factors is extremely scarce, although vital to get a comprehensive understanding of the effects of global change. We exposed six lichen species belonging to different functional groups to the combined effects of two nitrogen (N) doses and direct sunlight involving both high temperatures and ultraviolet (UV) radiation for 58 days. Irrespective of their functional group, all species showed a homogenous response to N with cumulative, detrimental effects and an inability to recover following sunlight, UV exposure. Moreover, solar radiation made a tolerant species more prone to N pollution’s effects. Our results draw attention to the combined effects of global change and other environmental drivers on canopy defoliation and tree death, with consequences for the protection of ecosystems.

Epiphytic lichens are used broadly as bioindicators, as they are sessile organisms with slow growth and different species display a wide range of environmental sensitivity. Most studies on epiphytic lichens focus on their use as indicators of the present environmental conditions, but few studies assess the changes that occur over decades. Comparative temporal approaches in lichens are rare, since there are few old datasets and in most cases substrates have disappeared, especially trees. However, in 1973 one of us (X. Llimona) described the lichen community on urban Populus alba in Jaca, and those trees are still alive. Our aim was to study the epiphytic lichen community in 2018 and compare it with the study of 1973. Species richness decreased during these 45 years. While only 36% of species found in 1973 persisted until 2018, these species remaining were observed at a high frequency in the 2018 sampling. Lichens communities from both years were similar on its tolerance to environmental variables, and the locality and their surroundings had the same land use in both years. Thus, the changes in lichen composition between both samplings might be explained by autogenic succession or limitation on dispersion rather than habitat filtering. Our data suggests that, under stable environments, lichen community assembly over decades depends on other traits such as competition rather than lichen sensitivity. Key words: autogenic succession; biotypes; community assembly; growth forms; photobiont; temporal changes.

We studied the biodiversity of Asterochloris photobionts found in Bolivian lichens to better understand their global spatial distribution and adaptation strategies in the context of a worldwide phylogeny of the genus. Based on nuclear ITS rDNA, the chloroplast rbcL gene and the actin type I gene we reconstructed a phylogenetic tree that recovered nine new Asterochloris lineages, while 32 Bolivian photobiont samples were assigned to 12 previously recognized Asterochloris lineages. We also show that some previously discovered Asterochloris photobiont species and lineages may occur in a broader spectrum of climatic conditions, and mycobiont species and photobionts may show diferent preferences along an altitude gradient. To reveal general patterns of of mycobiont specifcity towards the photobiont in Asterochloris, we tested the infuence of climate, altitude, geographical distance and efects of symbiotic partner (mycobiont) at the species level of three genera of lichen forming fungi: Stereocaulon, Cladonia and Lepraria. Further, we compared the specifcity of mycobionts towards Asterochloris photobionts in cosmopolitan, Neotropical, and Pantropical lichen forming fungi. Interestingly, cosmopolitan species showed the lowest specifcity to their photobionts, but also the lowest haplotype diversity. Neotropical and Paleotropical mycobionts, however, were more specifc.

Members of the poorly investigated family Teloschistaceae in South America, mostly from Bolivia and Peru, were examined using molecular and morphological data here for the first time. In recent phylogenetic reclassifications of Teloschistaceae, South American representatives were poorly represented but shown to belong to subfamilies Teloschistoideae and Xanthorioideae. In this study, we expanded the sampling of South American taxa and investigated mainly the lobate, sublobate, and squamulose members of Caloplaca s.l., using morphological characters and a molecular phylogeny based on a combined three-locus data set (one mitochondrial and two nuclear loci). Building upon new phylogenies at the family and subfamily levels (Teloschistoideae), we propose here three new genera: Andina, Aridoplaca, and Cinnabaria, with the type species Andina citrinoides, Aridoplaca peltata, and Cinnabaria boliviana. We also propose to reduce Tarasginia to synonymy with Sirenophila and Tayloriellina to synonymy with Villophora and introduce three new combinations: Dufourea ottolangei, D. volkmarwirthii, and Villophora erythrosticta. Scutaria andina is reported as new to Bolivia. A critical revision of the subfamily Brownlielloideae confirmed recent findings that it is an artifactual taxon based on a “chimeric” data set, with the type genus being part of Teloschistoideae.

In an era of rapid climate change and expansion of desertification, the extremely harsh conditions of drylands are a true challenge for microbial life. Under drought conditions, where most life forms cannot survive, rocks represent the main refuge for life. Indeed, the endolithic habitat provides thermal buffering, physical stability, and protection against incident ultraviolet (UV) radiation and solar radiation and, to some extent, ensures water retention to microorganisms. The study of these highly specialized extreme-tolerant and extremophiles may provide tools for understanding microbial interactions and processes that allow them to keep their metabolic machinery active under conditions of dryness and oligotrophy that are typically incompatible with active life, up to the dry limits for life. Despite lithobiontic communities being studied all over the world, a comprehensive understanding of their ecology, evolution, and adaptation is still nascent. Herein, we survey the fungal component of these microbial ecosystems. We first provide an overview of the main defined groups (i.e., lichen-forming fungi, black fungi, and yeasts) of the most known and studied Antarctic endolithic communities that are almost the only life forms ensuring ecosystem functionality in the ice-free areas of the continent. For each group, we discuss their main traits and their diversity. Then, we focus on the fungal taxonomy and ecology of other worldwide endolithic communities. Finally, we highlight the utmost importance of a global rock survey in order to have a comprehensive view of the diversity, distribution, and functionality of these fungi in drylands, to obtain tools in desert area management, and as early alarm systems to climate change.

Epiphytic lichens are a characteristic feature of many forests around the world, where they often cover large areas on stems and branches. Recently, it has been found that lichens may contribute substantially to carbon and nutrient uptake in forests. Moreover, they have a large influence on interception of rainfall at the global scale, which leads to a shift of the water balance toward evaporation and a cooling of near-surface air temperature. It is thus crucial to understand which environmental factors are relevant for their growth and survival, and which potential risks may result from climate change. Water supply is a key factor which controls active time and, consequently, the carbon balance of the epiphytes. However, it is largely unclear, to what extent different modes of water uptake, which include bark water, may affect active time and growth under varying environmental conditions. Quantitative estimates on the relevance of bark water storage and its interspecific variation are, however, missing. Here, we apply the process-based, dynamic non-vascular vegetation model LiBry to assess the relevance of bark water for epiphytic lichens. LiBry not only accounts for the main physiological processes of mosses and lichens, it also represents explicitly the diversity of the organisms, by simulating a large number of possible physiological strategies. We run the model for a site in Sardinia, where epiphytic lichens are abundant. Moreover, the Mediterranean region is of interest due to likely substantial effects of global warming on local epiphytes. For current climatic conditions, the LiBry model predicts net primary production (NPP) of 32 gCm−2a−1 per stem area and biomass of 48 gCm−2 for the study region. In a second run, where uptake of bark water is switched off in the model, estimated NPP is reduced by 21%. Moreover, the simulated number of surviving strategies, representing physiological diversity, decreases by 23%. This is accompanied by changes in the simulated community composition, where strategies which have a more compact thallus increase their share on the total cover. Hence, our model simulation suggests a substantial role of bark water for growth and morphology of epiphytic lichens in Sardinia. Keywords: vegetation model, ecophysiology, functional diversity, epiphytic lichen, Mediterranean vegetation, DGVM, non-vascular plants, precipitation partitioning.

Lichens are symbiotic associations (holobionts) established between fungi (mycobionts) and certain groups of cyanobacteria or unicellular green algae (photobionts). This symbiotic association has been essential in the colonization of terrestrial dry habitats. Lichens possess key mechanisms involved in desiccation tolerance (DT) that are constitutively present such as high amounts of polyols, LEA proteins, HSPs, a powerful antioxidant system, thylakoidal oligogalactolipids, etc. This strategy allows them to be always ready to survive drastic changes in their water content. However, several studies indicate that at least some protective mechanisms require a minimal time to be induced, such as the induction of the antioxidant system, the activation of non-photochemical quenching including the de-epoxidation of violaxanthin to zeaxanthin, lipid membrane remodeling, changes in the proportions of polyols, ultrastructural changes, marked polysaccharide remodeling of the cell wall, etc. Although DT in lichens is achieved mainly through constitutive mechanisms, the induction of protection mechanisms might allow them to face desiccation stress in a better condition. The proportion and relevance of constitutive and inducible DT mechanisms seem to be related to the ecology at which lichens are adapted to. Keywords: desiccation tolerance; lichen; phycobionts; poikilohydric; stress response.

The paper presents the results of the study on Platismatia species in Russia. The genus Platismatia counts 11 species, distributed mainly in the Pacific region, with some endemics of western North America and northeastern Asia. Six species were known from Russia by the beginning of our studies, but a revision of the herbarium collections showed that three species (P. erosa, P.herrei, and P. lacunosa) were reported erroneously. Based on morphological and chemotaxonomical (HPTLC) examination of the herbarium collections and our own material, as well as the study of relevant litera ture, four species of Platismatia are here accepted for Russia: P. glauca, P. interrupta, P.lacunosa, and P. norvegica. Platismatia lacunosa is reported here as a new for Russia from the Commander Islands. The distribution of P. glauca and P. interrupta is clarified. A key to all species of the genus reported from Russia and brief descriptions of the Russian species are presented. Keywords: Platismatia lacunosa, foliose lichens, herbarium, Commander Islands Nature and Biosphere Reserve, Russian Far East.

The lichen diversity of the Cape Goven within the Koryak State Reserve counts 394 species: 373 lichens, 18 lichenicolous fungi and 3 non-lichenized saprobic fungi related to lichens. Altogether 4 species are new to Russia (Miriquidica pulvinatula, Myriolecis andrewii, Ochrolechia alaskana, Rhizocarpon sublavatum), 1— to Asiatic Russia (Collemopsidium foveolatum), 29other species are new to the Russian Far East, 4— to the northern part of the Far East. Additionally, 51 other species are new to Kamchatka Territory, and 92 more are new to Koryakia. Among the new species to Russia or Russian Far East, 11 are also reported for the first time for Beringia. A total of 500 species of lichens and allied fungi are known from Koryakia now. The richest habitats in Cape Goven are rocky outcrops and tundras; unlike in the earlier explored Parapolsky Dale, shrublands, floodplain stands and bogs play relatively insignificant role in the lichen diversity. The lichens of seashore communities enrich the lichen flora of Cape Goven compared to inland areas. The lichen diversity of Cape Goven is significantly higher than in Parapolsky Dale due to its mountainous landscape and coastal position.

Atheliales (Agaricomycetes, Basidiomycota) is an order mostly composed of corticioid fungi, containing roughly 100 described species in 20 genera. Members exhibit remarkable ecological diversity, including saprotrophs, ectomycorrhizal symbionts, facultative parasites of plants or lichens, and symbionts of termites. Ectomycorrhizal members are well known because they often form a major part of boreal and temperate fungal communities. However, Atheliales is generally understudied, and molecular data are scarce. Furthermore, the order is riddled with many taxonomic problems; some genera are nonmonophyletic and several species have been shown to be more closely related to other orders. We investigated the phylogenetic position of genera that are currently listed in Atheliales sensu lato by employing an Agaricomycetes-wide dataset with emphasis on Atheliales including the type species of genera therein. A phylogenetic analysis based on 5.8S, LSU, rpb2, and tef1 (excluding third codon) retrieved Atheliales in subclass Agaricomycetidae, as sister to Lepidostromatales. In addition, a number of Atheliales genera were retrieved in other orders with strong support: Byssoporia in Russulales, Digitatispora in Agaricales, Hypochnella in Polyporales, Lyoathelia in Hymenochaetales, and Pteridomyces in Trechisporales. Based on this result, we assembled another dataset focusing on the clade with Atheliales sensu stricto and representatives from Lepidostromatales and Boletales as outgroups, based on ITS (ITS1 e5.8SeITS2), LSU, rpb2, and tef1. The reconstructed phylogeny of Atheliales returned five distinct lineages, which we propose here as families. Lobulicium, a monotypic genus with a distinct morphology of sevenlobed basidiospores, was placed as sister to the rest of Atheliales. A new family is proposed to accommodate this genus, Lobuliciaceae fam. nov. The remaining four lineages can be named following the family-level classification by Jülich (1982), and thus we opted to use the names Atheliaceae, Byssocorticiaceae, Pilodermataceae, and Tylosporaceae, albeit with amended circumscriptions. Keywords: Agaricomycetes; Basidiomycota; Corticioid fungi; Multi-locus phylogeny; Family-level taxonomy.

Atranorin (ATR), lichenized secondary metabolite and depside molecule with several biological potentials such as antimicrobial, anticancer, anti-inflammatory, antinociceptive, wound healing and photoprotective activities. Cytotoxic reports of ATR are documented in several cancer cells and in vivo models but its molecular interaction studies are poorly understood. Therefore, in this present investigation, we have used the in silico studies with biological validation of the molecular targets for the anti-breast cancer mechanism of ATR. The molecular docking studies with the breast cancer oncoproteins such as Bcl-2, Bax, Akt, Bcl-w and Bcl-xL revealed the highest interaction was observed with the Akt followed by Bax, Bcl-xL and Bcl-2 & least with the Bcl-w proteins. The cytotoxicity studies showed ATR selectively inhibited MDA MB-231 and MCF-7 breast cancer cells in differential and dosedependent manner with the IC50 concentration of 5.36 ± 0.85 lM and 7.55 ± 1.2 lM respectively. Further mechanistic investigations revealed that ATR significantly inhibited ROS production and significantly down-regulated the anti apoptotic Akt than Bcl-2, Bcl-xL and Bcl-w proteins with a significant increase in the Bax level and caspases-3 activity in the breast cancer cells when comparison with Akt inhibitor, ipatasertib. In vitro biological activities well correlated with the molecular interaction data suggesting that atranorin had higher interaction with Akt than Bax and Bcl-2 but weak interaction with Bcl-w and Bcl-xL. In this present study, the first time we report the interactions of atranorin with molecular targets for anti-breast cancer potential. Hence, ATR represents the nature-inspired molecule for pharmacophore moiety for design in targeted therapy. Keywords: Breast cancer; interaction; cytotoxicity; atranorin; biological validation.

The aim of the study was to examine the changes in ecophysiological parameters and accumulation of heavy metals in lichens transplanted to a shooting-range environment. Thalli of the epiphytic lichen were transplanted from an unpolluted site to a shooting range. Chlorophyll a fluorescence, thiobarbituric acid reactive substances (TBARS), and damage to cell membranes in the lichen Evernia prunastri and Ramalina farinacea thalli were determined after 3 months exposure period indoors in a shooting range. The concentrations of some heavy metals including cadmium, copper, iron, manganese, nickel, lead, antimony, and zinc were measured in lichens as indicators of the levels of air pollution in the studied environment. Thalli of the lichens transplanted to the shootingrange environment showed stress symptoms where the presence of metal pollutants produced a loss of integrity of lichen cell membranes and induced oxidative stress as evidenced by increased levels of TBARS. The response of lichens transplanted to indoors of shooting range demonstrated a significant accumulation of Pb indicating potential increased metal exposure and consequent adverse health effects. Keywords: Shooting range; trace metals; lichens; indoor pollution; Pb.

Because microbes cannot be eliminated from radioactive waste disposal facilities, the consequences of bio-colonization must be understood. At a pre-Viking era vitrified hillfort, Broborg, Sweden, anthropogenic glass has been subjected to bio-colonization for over 1,500 years. Broborg is used as a habitat analogue for disposed radioactive waste glass to inform how microbial processes might influence long-term glass durability. Electron microscopy and DNA sequencing of surficial material from the Broborg vitrified wall, adjacent soil, and general topsoil show that the ancient glass supports a niche microbial community of bacteria, fungi, and protists potentially involved in glass alteration. Communities associated with the vitrified wall are distinct and less diverse than soil communities. The vitrified niche of the wall and adjacent soil are dominated by lichens, lichen-associated microbes, and other epilithic, endolithic, and epigeic organisms. These organisms exhibit potential bio-corrosive properties, including silicate dissolution, extraction of essential elements, and secretion of geochemically reactive organic acids, that could be detrimental to glass durability. However, long-term biofilms can also possess a homeostatic function that could limit glass alteration. This study documents potential impacts that microbial colonization and niche partitioning can have on glass alteration, and subsequent release of radionuclides from a disposal facility for vitrified radioactive waste. Keywords: Community structure; habitat analogue; microbes and surfaces; molecular ecology; near surface radioactive waste disposal.

There is deepening interest in how microclimatic refugia can reduce species threat, if suitable climatic conditions are maintained locally, despite global climate change. Microclimates are a particularly important consideration in topographically heterogeneous landscapes, while in some habitats, such as forests and woodlands, microclimates are also extremely labile and affected by management practices that could consequently be used to offset climate change impact. This study explored a conservation priority guild—cyanolichen epiphytes in temperate rainforest—quantifying the niche response to macroclimate, and landscape or woodland stand structures that determine the microclimate. Based on epiphyte survey in a core region of European temperate rainforest (western Scotland), a ‘random forest’ machine-learning model confirmed a strong cyanolichen response to summer dryness, as well as the effects of distance to running water, topographic heatload and tree species identity, which modify the local moisture regime and/or lichen growth rates. By quantifying this response to macroclimate, landscape and stand structures, it was possible to estimate an extent to which woodland may be expanded in the future, to offset a negative effect of increasing summer dryness projected through to the 2080s. Using current policy as a yardstick, sufficient woodland expansion could be delivered relatively quickly for median impacted sites, but with times to woodland delivery extending over 10, 20 and 25 years for sites at the 75th, 90th and 95th percentiles of cyanolichen decline. Furthermore, the extent of new woodland required, and delivery times, increase almost threefold on average, as new woodland becomes distributed over wider riparian zones. These contrasting implications emphasize an urgent need for afforestation that achieves targeted spatial planning responsive to microclimates as refugia. Keywords: climate change adaptation, epiphytes, microclimate, moisture index, reforestation, riparian woodland, summer drought.

We evaluate stability of cesium (Cs) and other alkali-metal cation complexes of lichen metabolites in both gas and aqueous phases to discuss why lichens can retain radioactive Cs in the thalli over several years. We focus on oxalic acid, (+)-usnic acid, atranorin, lecanoric acid, and protocetraric acid, which are common metabolite substances in various lichens including, e.g., Flavoparmelia caperata and Parmotrema tinctorum retaining Cs in Fukushima, Japan. By performing quantum chemical calculations, their gas-phase complexation energies and aqueous-solution complexation free energies with alkali-metal cations are computed for their neutral and deprotonated cases. Consequently, all the molecules are found to energetically favor cation complexations and the preference order is Li+ >Na+ >K+ >Rb+ >Cs+ for all conditions, indicating no specific Cs selectivity but strong binding with all alkali cations. Comparing complexation stabilities among these metabolites, lecanoric and protocetraric acids seen in medullary layer are found to keep higher affinity in their neutral case, while (+)-usnic acid and atranorin in upper cortex exhibit rather strong affinity only in deprotonated cases through forming stable six atoms’ ring containing alkali cation chelated by two oxygens. These results suggest that the medullary layer can catch all alkali cations in a wide pH range around the physiological one, while the upper cortex can effectively block penetration of metal ions when the metal stress grows. Such insights highlight a physiological role of metabolites like blocking of metalcation migrations into intracellular tissues, and explain long-term retention of alkali cations including Cs in lichens containing enough such metabolites to bind them.

[in Italian with English abstract: ] The threat to the survival of many species, caused by emerging ecological crises, has favored the development of a new environmental awareness. In recent decades, especially in the most industrialized nations, an increasing participation of citizens in the collection of scientific data has also been recorded. The active involvement of society in different aspects of science has been defined by the sociologist Alan Irwin as “Citizen Science”. Although environmental Citizen Science brings together the largest number of projects, the fields of application of this new way of doing science are innumerable. BioBlitz is one of the best-known examples of citizen science activities, aimed at monitoring the biodiversity of an area. The Maremma Natural History Museum, as part of its activities, regularly organizes BioBlitz on an annual basis, starting from 2013. During BioBlitz 2017 in the SPZ and SCZ “Monte Labbro and Alta Valle dellAlbegna” data were collected attesting the presence of 403 different taxonomic entities, of which 367 identified at the species level and 5 at the subspecies level. Six alien and 2 endemic species were identified. In terms of environmental legislation, 38 protected species and 7 endangered species were detected in the area. The most relevant aspect that emerges from the collected data is the consistent number of protected species. This confirms the environmental value of the area and the need for management and conservation plans for the entire site.

[in Italian with English abstract: ] In recent decades, many natural history museums in Europe have integrated their traditional functions with new ways of interacting with visitors and local communities. In particular, the need to adapt their mission according to the changes in modern society has led them to develop initiatives aiming at an active involvement of the public in scientific research. This is one of the inspiring principles of Citizen Science. BioBlitz are among the most popular activities dedicated to biodiversity in this field. In line with the inspiring principles of this cultural revolution, since 2012 the Maremma Natural History Museum organized public participation initiatives for the collection of biodiversity data. We hereby report the main results of the BioBlitz 2018 organized by the Maremma Natural History Museum in the Talamone area, located in the southern portion of the Uccellina Hills. Four hundred and ninety eight taxa were sampled and identified, 447 of which at the level of species and 10 at the level of subspecies; the remaining refer to higher taxonomic levels. 31 protected species and 10 endangered species were found in the area; moreover, 6 alien species and one endemic species were detected. The main feature that distinguished BioBlitz 2018 to others conducted in previous years was the large number of participants. The data collected increased the scientific knowledge of the southern portion of the Maremma Regional Park, less known than other areas of the same protected area.

The spatial distribution of corticolous lichens on the iconic New Zealand pōhutukawa (Metrosideros excelsa) tree was investigated from a survey of urban parks and forests across the city of Auckland in the North Island of New Zealand. Lichens were identified from ten randomly selected trees at 20 sampling sites, with 10 sites classified as coastal and another 10 as inland sites. Lichen data were correlated with distance from sea, distance from major roads, distance from native forests, mean tree DBH (diameter at breast height) and the seven-year average of measured NO2 over the area. A total of 33 lichen species were found with coastal sites harboring significantly higher average lichen species per tree as well as higher site species richness. We found mild hotspots in two sites for average lichen species per tree and another two separate sites for species richness, with all hotspots at the coast. A positive correlation between lichen species richness and DBH was found. Sites in coastal locations were more similar to each other in terms of lichen community composition than they were to adjacent inland sites and some species were only found at coastal sites. The average number of lichen species per tree was negatively correlated with distance from the coast, suggesting that the characteristic lichen flora found on pōhutukawa may be reliant on coastal microclimates. There were no correlations with distance from major roads, and a slight positive correlation between NO2 levels and average lichen species per tree.

Current trends emphasize the importance of the examination of the functional composition of lichens, which may provide information on the species realized niche diversity and community assembly processes, thus enabling one to understand the specific adaptations of lichens and their interaction with the environment. We analyzed the distribution and specialization of diverse morphological, anatomical and chemical (lichen secondary metabolites) traits in lichen communities in a close-to-natural forest of lowland Europe. We considered these traits in relation to three levels of forest ecosystem organization: forest communities, phorophyte species and substrates, in order to recognize the specialization of functional traits to different levels of the forest complexity. Traits related to the sexual reproduction of mycobionts (i.e., ascomata types: lecanoroid apothecia, lecideoid apothecia, arthonioid apothecia, lirellate apothecia, stalked apothecia and perithecia) and asexual reproduction of mycobionts (pycnidia, hyphophores and sporodochia) demonstrated the highest specialization to type of substrate, tree species and forest community. Thallus type (foliose, fruticose, crustose and leprose thalli), ascospore dark pigmentation and asexual reproduction by lichenized diaspores (soredia and isidia) revealed the lowest specialization to tree species and substrate, as well as to forest community. Results indicate that lichen functional trait assemblage distribution should not only be considered at the level of differences in the internal structure of the analyzed forest communities (e.g., higher number of diverse substrates or tree species) but also studied in relation to specific habitat conditions (insolation, moisture, temperature, eutrophication) that are characteristic of a particular forest community. Our work contributes to the understanding of the role of the forest structure in shaping lichen functional trait composition, as well as enhancing our knowledge on community assembly rules of lichen species. Keywords: functional traits composition; substrates; phorophytes; forest communities; Białowieża Forest.

The discovery of Teloschistes chrysophthalmus in Connecticut more than one hundred years since its last known occurrence is argued to result from human introduction. The species only occurred on the horticultural tree, Gleditsia triacanthos var. inermis, planted on the University of Connecticut campus. Gleditsia triacanthos is not indigenous to northeastern North America but is widespread in the central United States. Other epiphytic macrolichens also recorded on this phorophyte include Punctelia bolliana and Parmotrema austrosinense, both widespread in the central United States, and new to Connecticut and New England, respectively. This is likely the first reported case of combined introductions of lichenized fungi in North America through the import of ornamental trees.

Biodiversity varies with elevation and is affected by disturbances. However, little is known about how the associations between the diversities of different bryophyte and macrolichen functionaltaxonomic groups are altered along elevational gradients and by disturbances. Knowledge on the associations between these functional-taxonomic groups might be of importance in practical conservation biology, as identifying indicator taxa which are easy to monitor could be useful in estimating a wider biodiversity. We sampled the species richness of bryophytes and macrolichens in 92 plots distributed in disturbed and undisturbed stands along elevational gradients in the laurel forest of Madeira. We then calculated a matrix of correlations for all pairwise combinations of 18 different functional-taxonomic bryophyte and macrolichen groups and tested for average differences in correlations with elevation and disturbance history and whether particular functional-taxonomic groups can be used to estimate the richness of other taxa. Associations between the diversities of functionaltaxonomic groups within the bryophyte group and within the macrolichen group were always positive and mainly strong. Although changes in elevation and disturbance history changed the associations between the different bryophyte and macrolichen functional-taxonomic groups, we found the species richness of mosses or liverworts to be suitable for predicting overall bryophyte species richness and the species richness of green-algae macrolichens to be reliable for estimating overall macrolichen species richness. Associations between diversities of bryophyte and macrolichen groups were generally weak, suggesting that the two groups have different ecological requirements and do not share the same environmental drivers. The fact that no single bryophyte taxon can be used to predict the richness of any macrolichen group, and vice versa, points to the need to study both bryophytes and lichens. However, we found indicator taxa that are relatively easy to monitor and therefore could be used to estimate the wider biodiversity. Keywords: Biodiversity indicators, bryophyte life strategy, elevation, endemic species, disturbance, functional-taxonomic group, lichen growth form, liverwort, moss, photobiont.

Five macrolichens of different thallus morphology from Antarctica (King George Island) were used for this ecophysiological study. The effect of thallus desiccation on primary photosynthetic processes was examined. We investigated the lichens’ responses to the relative water content (RWC) in their thalli during the transition from a wet (RWC of 100%) to a dry state (RWC of 0%). The slow Kautsky kinetics of chlorophyll fluorescence (ChlF) that was recorded during controlled dehydration (RWC decreased from 100 to 0%) and supplemented with a quenching analysis revealed a polyphasic species-specific response of variable fluorescence. The changes in ChlF at a steady state (Fs), potential and effective quantum yields of photosystem II (FV/FM, ΦPSII), and nonphotochemical quenching (NPQ) reflected a desiccation-induced inhibition of the photosynthetic processes. The dehydration-dependent fall in FV/FM and ΦPSII was species-specific, starting at an RWC range of 22–32%. The critical RWC for ΦPSII was below 5%. The changes indicated the involvement of protective mechanisms in the chloroplastic apparatus of lichen photobionts at RWCs of below 20%. In both the wet and dry states, the spectral reflectance curves (SRC) (wavelength 400–800 nm) and indices (NDVI, PRI) of the studied lichen species were measured. Black Himantormia lugubris showed no difference in the SRCs between wet and dry state. Other lichens showed a higher reflectance in the dry state compared to the wet state. The lichen morphology and anatomy data, together with the ChlF and spectral reflectance data, are discussed in relation to its potential for ecophysiological studies in Antarctic lichens.

This study investigated the accumulation and phytotoxicity of two commercial biocides widely used for the removal of biological colonization from monuments, namely Biotin T® (3%) and Preventol RI80® (2%), on lichen and moss model species, specifically, Evernia prunastri and Brachythecium sp. The active compounds, benzalkonium chloride (BAC) for Preventol RI80 and isothiazolinone (OIT) for Biotin T, were accumulated in similar amounts in both species without significant changes for up to 21 days. Both compounds caused a severe impairment of the photosynthetic apparatus of these species, without any recovery over time, although Biotin T showed a faster and stronger action, and the moss was more sensitive than the lichen. By shedding light on the accumulation of BAC and OIT in lichens and mosses and quantifying their effectiveness to photosynthetically devitalize these organisms, the obtained results are a useful comparison for the implementation of green alternative products for the control of biodeteriogens. Keywords: benzalkonium chloride; biocidal compounds; n-octyl-isothiazolinone; photosynthesis; uptake.

Green synthesis of nanoparticles (NPs) is a safe, eco-friendly, and relatively inexpensive alternative to conventional routes of NPs production. These methods require natural resources such as cyanobacteria, algae, plants, fungi, lichens, and naturally extracted biomolecules such as pigments, vitamins, polysaccharides, proteins, and enzymes to reduce bulk materials (the target metal salts) into a nanoscale product. Synthesis of nanomaterials (NMs) using lichen extracts is a promising eco-friendly, simple, low-cost biological synthesis process. Lichens are groups of organisms including multiple types of fungi and algae that live in symbiosis. Until now, the fabrication of NPs using lichens has remained largely unexplored, although the role of lichens as natural factories for synthesizing NPs has been reported. Lichens have a potential reducible activity to fabricate different types of NMs, including metal and metal oxide NPs and bimetallic alloys and nanocomposites. These NPs exhibit promising catalytic and antidiabetic, antioxidant, and antimicrobial activities. To the best of our knowledge, this review provides, for the first time, an overview of the main published studies concerning the use of lichen for nanofabrication and the applications of these NMs in different sectors. Moreover, the possible mechanisms of biosynthesis are discussed, together with the various optimization factors influencing the biological synthesis and toxicity of NPs.

Large-scale efforts to aggregate and promote the re-use of biodiversity data are leading to novel insights into biogeography and macroecology. However, secondary analyses must account for the tradeoffs and limitations of the original studies. Studies of speciose and taxonomically complex groups often utilize morphospecies or functional subsets as proxies, potentially complicating data re-use. We evaluated whether lichen biodiversity patterns are robust to differences in sampling methodology, utilizing parallel analyses to compare species richness, regional species pool variation, species probabilities of occurrence, and correlation of those three with environmental variables in data sets that cover the same geographic region. Our analyses revealed that, although individual species distributions sometimes differed in idiosyncratic ways, inference based on the aggregated response of multiple species was generally robust across the two datasets, despite differences in observer expertise and functional and taxonomic scope. This suggests that biodiversity data assembled from disparate sources could be used to evaluate biogeographical and macroecological hypotheses in understudied groups such as lichens, particularly at larger spatial scales.

The Southern Ocean landmasses have intrigued biologists for centuries because they share many taxonomic groups. Such disjunct taxa can provide insight into evolutionary processes that connect populations or drive divergence. The lichenized fungus Pseudocyphellaria glabra, for example, has a disjunct distribution—separated by the Tasman Sea and the Pacific Ocean—yet whether these locations should be genetically distinct is unclear. The large distances between continents may be expected to prohibit gene flow, but strong and sustained winds in the Southern Hemisphere and the small size of P. glabra propagules may facilitate migration. We compared support for these two hypotheses. Keywords: biogeography; dispersal; evolution; lichen; lichenized fungi; population genetics; subantarctic; systematics.

Research suggests that the World Heritage rock engravings in Alta, Northern Norway, were made along the seashore over a period of 5000 years. The postglacial rebound and consequent land uplift have caused a continuous displacement of the shoreline, now situating the earliest rock art panels up to 26m above sea level. By examining the rock surfaces at Hjemmeluft and other sites, using field observations and geological analyses, we found that the pronounced red bedrock surfaces in the current seashore zone are composed of inorganic iron films related to a high content of magnetite in the native sandstone. Coupled with an interpretation of regional environmental history, we also found that it is highly likely that the rock art was originally carved on rocks with red iron films, rocks that are now generally gray. Due to the land uplift and subsequent covering of the rock art with lichen, moss, and turf, the red color has waned at the rock art sites. This knowledge may renew interpretation and understanding of the location of rock art in Alta and may have implications for conservation and management. Keywords: colors, esthetics, iron films, rock art, rock coatings.

Several studies have evaluated lichen responses in terms of shifts in species climate suitability, species richness and community composition. In contrast, patterns of co‐occurrence among species that could be related to complex species interactions have received less consideration. Biotic interactions play a major role in shaping species niches, fitness and adaptation to new environments. Therefore, considering the specific relationships among co‐occurring species is essential to further deepen our knowledge of biodiversity response to climate change. In this perspective, the analysis of lichen ecological networks across elevational gradients may provide a powerful tool to understand how communities are structured and how biotic interactions are modulated by changing climatic conditions. We evaluated the contribution of environmental and species biological attributes to the structure of epiphytic lichen–host tree networks. Specifically, we studied lichen communities considering two different network levels: the whole lichen community, and groups of lichen species that presented similar biological traits. In this framework, we (a) characterized the structure of the epiphytic lichen–host tree networks; (b) assessed how network structure varied with climate, forest attributes and community trait diversity and (c) evaluated the role that biological traits played in the connections established between co‐occurring lichens. On the one hand, results indicate that epiphytic lichen communities are dominated by local segregation, suggesting habitat specialization among lichens within their host tree, and that climatic conditions and, to a lesser extent, lichen diversity are the main drivers of community assemblage. On the other hand, the role of lichen species in the networks depends on their particular biological traits, supporting the hypothesis that biological traits contribute to shape network structure by influencing the ability of the species to interact between each other. These findings warn about the potential impact of climate change on epiphytic lichen communities. Synthesis. This study builds towards a better understanding of lichen community assembly and on biodiversity response to climate change in forest alpine ecosystems. In particular, our results highlight the value of lichen–tree networks to inform about assemblage processes acting at different organizational levels and indicate that lichens might become one of the most threatened groups under global change scenarios. Keywords: alpine ecosystems; biological traits; climate change; determinants of community structure and diversity; elevation gradients; epiphyte networks.

For the first time we document several species of micro-mollusks in the Galapagos inhabiting lichens and bryophytes, possibly using them as part of their diet. Eight species of micro-mollusks were found as a by-catch among 10% of 400 herbarium specimens collected throughout the archipelago. Nine species of lichens and 6 of bryophytes were inhabited. The endemic Pupisoma galapagorum was the most common micro-mollusk, particularly frequent among Heterodermia, occasionally found on Cyphellostereum, Squamidium nigricans, and among hepatics (Frullania, Bryopteris). Other micromollusks were Tornatellides chathamensis, Pupisoma dioscoricola, Helicina sp., and Succinea sp. Examination of the digestive tract of P. galapagorum detected green algae, hyphae, spores, and fragments of bryophyte leaves (possibly S. nigricans). This endemic micro-mollusk apparently uses lichens and bryophytes not only for shelter but also as food. Another snail found repeatedly is a predator, described here as Scolodonta rinae n. sp. It is a member of Scolodontidae, a Neotropical family considered endemic to continental South America, and here for the first time documented from the Galapagos. Pupisoma galapagorum, previously known from Floreana, Isabela, San Cristóbal, and Santa Cruz, is reported also from Pinta and Santiago. Ambrosiella floreanae, previously considered endemic to Floreana, is reported from Santa Cruz. Key words: Ecological interactions, land snail, microhabitats, food-chain.

Mankind has been altering native forests in Macaronesia for at least five centuries. Forestry practices are known to reduce biodiversity due to habitat loss, fragmentation and alteration. To assess the potential of plantations to provide habitat for epiphytic lichens in comparison with native forests, we examined three types of forest in the Canary Islands: laurel forest (native forest) and two monospecific plantations of Pinus radiata and Eucalyptus globulus. Epiphytic lichen diversity was evaluated using a methodology of species richness and lichen diversity values (LDV). Our results demonstrate that the conversion of laurel forests to monoculture plantations of exotic tree species decreases lichen diversity and alters lichen community composition. Our findings hightlight how native epiphytic lichens from the cloud forest cannot survive under the same climatic conditions if the host plant community is changed. Keywords: Canary Islands; Exotic plantations; Laurel forest; Lichen diversity; Macaronesia.

Questions: Can bark characteristics be used to determine the suitability of trees to host epiphytic bryophytes and lichens or are other tree and site characteristics more important? Identification of substitute hosts is required in the face of epidemic tree deaths due to diseases that are a threat to affiliated epiphytic communities. We assess the suitability of seven phorophytes to host the epiphytes associated with the UK native oak species, Quercus petraea and Quercus robur, which are currently threatened by a range of pests and pathogens. Location: Six botanic gardens and arboreta across the UK. Method: We recorded the site, habitat, tree (height, diameter at breast height [1.3 m; DBH], percentage canopy cover) and bark characteristics (pH, conductivity, density, water‐holding capacity, hardness, topography) and epiphytic community composition on Acer pseudoplatanus, Castanea sativa, Fagus sylvatica, Fraxinus excelsior, Quercus cerris, Quercus petraea, Quercus robur, Quercus rubra and Tilia × europaea. In total 230 trees were surveyed across the six sites. Results: Comparisons between all trees showed significant correlations between similarities in community composition and bark characteristics. However, “tree characteristics” (species, height, DBH and canopy over) explained more of the variation in epiphytic community composition than bark and site characteristics. Phorophytes with similar epiphytic community richness or composition to native oaks did not necessarily have similar bark characteristics. Non‐native oaks and the non‐native hybrid Tilia × europaea supported similar epiphyte communities to the native oaks and are suggested as substitute phorophytes. Conclusion: Using bark traits is not a reliable method to assess the suitability of substitute phorophytes to conserve epiphytic communities. Instead, the epiphytes hosted by a wider range of phorophytes should be recorded to allow an assessment of their suitability as substitute hosts and hence aid management decisions on replacement phorophytes following tree loss.

We discuss the taxonomy of three species of Bacidia occurring in insular Laurimacaronesia. Two of them, B. amylothelia (Vain.) Vain. and B. endoleucoides (Nyl.) Zahlbr., which were previously described from Angola and Madeira, respectively, are found here to belong in Bacidia s. str. (Ramalinaceae). Modern descriptions and illustrations are provided for the first time. Bacidia amylothelia is similar to B. areolata Gerasimova & A. Beck, B. campalea (Tuck.) S. Ekman & Kalb, B. fusconigrescens (Nyl.) Zahlbr., B. heteroloma (Vain.) Zahlbr., B. millegrana (Taylor) Zahlbr. and B. suffusa (Fr.) A. Schneid. and is reported here from the Canary Islands. Bacidia endoleucoides is most likely to be confused with B. absistens (Nyl.) Arnold, B. friesiana (Hepp) Körb., B. salazarensis B. de Lesd. and B. caesiovirens S. Ekman & Holien and was found to be widely distributed in the Canary Islands and Azores in addition to Madeira. The third species, Bacidia deludens S. Ekman, Tønsberg & van den Boom, is described here as new to science. Bacidia deludens is characterised by a greyish, crustose thallus with whitish soralia, pale apothecia with crystals in the hymenium and proper exciple, acicular ascospores with 3–19 septa, and the production of fumarprotocetraric acid as the consistently present major substance. It is described here from the Canary Islands and Madeira. Although conservatively treated here in Bacidia, we argue that it is likely to belong in the Malmideaceae. An identification key to all known species of Bacidia s. str. in insular Macaronesia is provided. Keywords: Bacidia, determination key, Malmideaceae, new species, Ramalinaceae.

Lichens represent self-supporting symbioses, which occur in a wide range of terrestrial habitats and which contribute significantly to mineral cycling and energy flow at a global scale. Lichens usually grow much slower than higher plants. Nevertheless, lichens can contribute substantially to biomass production. This review focuses on the lichen symbiosis in general and especially on the model species Lobaria pulmonaria L. Hoffm., which is a large foliose lichen that occurs worldwide on tree trunks in undisturbed forests with long ecological continuity. In comparison to many other lichens, L. pulmonaria is less tolerant to desiccation and highly sensitive to air pollution. The namegiving mycobiont (belonging to the Ascomycota), provides a protective layer covering a layer of the green-algal photobiont (Dictyochloropsis reticulata) and interspersed cyanobacterial cell clusters (Nostoc spec.). Recently performed metaproteome analyses confirm the partition of functions in lichen partnerships. The ample functional diversity of the mycobiont contrasts the predominant function of the photobiont in production (and secretion) of energy-rich carbohydrates, and the cyanobiont’s contribution by nitrogen fixation. In addition, high throughput and state-of-the-art metagenomics and community fingerprinting, metatranscriptomics, and MS-based metaproteomics identify the bacterial community present on L. pulmonaria as a surprisingly abundant and structurally integrated element of the lichen symbiosis. Comparative metaproteome analyses of lichens from different sampling sites suggest the presence of a relatively stable core microbiome and a sampling site-specific portion of the microbiome. Moreover, these studies indicate how the microbiota may contribute to the symbiotic system, to improve its health, growth and fitness.

Community ecology has experienced a major transition, from a focus on patterns in taxonomic composition, to revealing the processes underlying community assembly through the analysis of species functional traits. The power of the functional trait approach is its generality, predictive capacity such as with respect to environmental change, and, through linkage of response and effect traits, the synthesis of community assembly with ecosystem function and services. Lichens are a potentially rich source of information about how traits govern community structure and function, thereby creating opportunity to better integrate lichens into ‘mainstream’ ecological studies, while lichen ecology and conservation can also benefit from using the trait approach as an investigative tool. This paper brings together a range of author perspectives to review the use of traits in lichenology, particularly with respect to European ecosystems from the Mediterranean to the Arctic-Alpine. It emphasizes the types of traits that lichenologists have used in their studies, both response and effect, the bundling of traits towards the evolution of life-history strategies, and the critical importance of scale (both spatial and temporal) in functional trait ecology. Keywords: ecosystem services; effect traits; functional ecology; lichenised-fungi; life-history strategy; response traits; scale; spatial; temporal.

This study analyzes data of moss/lichen biocrusts on volcanic tephra at 2335 m in Haleakalā Crater (Maui, Hawai’i). Samples were compared among three adjacent positions: rolling crusts, pinnacled crusts, and bare tephra; two profiles contrasted substrate variation in crust and tephra areas. Field experiments assessed soil shear- and compressive-strength, infiltration rates, and diurnal soil temperatures; a lab experiment measured evaporation from crust specimens for 9 days. Biocrusts significantly affected physical, chemical, and structural soil properties. Fine particles, organic matter, and water storage were appreciably greater in biocrusts. Micro-sampling indicated upper-pinnacle sections accumulated more fine grains due to capture of volcanic ash, and also contained greater organic matter, than lower-pinnacle portions. Crust areas experienced infiltration rates ~2.8 times faster than tephra; mean diurnal temperatures were 12.1 ◦C (26.9 vs 39.0 ◦C) cooler in crusts than in tephra. Saturated crust specimens stored ~2.7 times more moisture than tephra soils; slower evaporation in biocrusts significantly lengthened the period over which poikilohydric cryptogams are able to maintain meta-bolic activity. Soil shear- and compressive-strength were higher on crusts than on tephra. Biocrust soils showed greater fertility, as available Ca2+, Mg2+, K+, P, NH4+-N, and cation-exchange capacity were higher than in tephra. NH4+-N was more concentrated under rolling crusts than in pinnacled ones; this is mainly ascribed to sampling methodology. Buried profile horizons suggest the site experienced additional tephra deposition during episodic volcanic eruptions. A developmental model assesses interactions among soil and environmental pro-cesses, and provides an integrated geoecological view of linkages that influenced biocrust genesis.

1. Mires are characterized by plant communities of high conservation and societal value, which have experienced a major decline in area in many parts of the world, particularly Europe. Evidence suggests that they may be particularly vulnerable to changes in climate and nutrient addition. Although they have been the focus of extensive paleoecological research, few attempts have been made to examine the dynamics of mire vegetation during the current era of anthropogenic environmental change. 2. To assess long-term change in the spatial structure and composition of a lowland mire community, in 2016 we resurveyed plots first surveyed in 1951. Measures of species richness and composition were compared between the two surveys, and changes in community composition were related to plant traits. 3. Overall, mean species richness declined by 26%. The area of occupancy declined in 37% of species, which were primarily oligotrophic species typical of nutrientpoor bog communities. Conversely, occupancy increased in 21% of species, especially those that were more tolerant of higher nutrient availability. These changes were associated with variation in plant functional traits, as indicated by an increase mean Ellenberg trait values for nitrogen and mean temperature, and a decline in values for precipitation. These results suggest that eutrophication and climate change have been key drivers of floristic change on this site. 4. Synthesis. This investigation provides a rare assessment of the dynamics of a mire community over a multi-decadal interval. Results indicate that substantial change has occurred in the composition of the community, and the distribution of species within it. The investigation provides evidence of the impact of environmental change on the composition and structure of a lowland mire community, and highlights challenges for its future conservation. Keywords: biodiversity, bog, conservation, determinants of plant community diversity and structure, environmental change, peatland, plant distribution.

Chemical investigation of the lichen Parmotrema praesorediosum (Nyl.) Hale led to isolate six phenolic compounds including praesorediosic (1), orcinol (2), orselinic acid (3), lecanorin (4), isolecanoric acid (5) and virensic acid (6). Among them, compound 1 appeared to be found for the first time in the nature. The structure of these compounds was elucidated by spectroscopic analyses of HRESIMS and NMR as well as the comparison of their NMR data with those in the literature. These compounds were evaluated for their cytotoxicity using sulforhodamine‐B assay against HeLa (human epithelial carcinoma), NCI‐H460 (human lung cancer), HepG2 (liver hepatocellular carcinoma) and MCF‐7 (human breast cancer) cell lines.

Gap analysis of the available genomic data (i.e. identifying taxonomic groups with no representative genome assemblies) is a fundamental first step to design effective sampling strategies for whole genome sequencing (WGS) initiatives. We identified the significant holes that remain in genomic resources of the Ascomycota e the largest fungal phylum including many species of medicinal, ecological and/or economic significance e in order to prioritise WGS efforts towards reconstructing the Ascomycota tree of life. In doing so, we additionally looked at the existing genome size data for ascomycetes, given the importance of knowing the size of the genome to ensure sufficient sequencing coverage and assess the completeness and quality of genome assemblies. We found that 50 % of the ascomycete orders have no representative genome assembly and over 75 % have no reliably measured genome size data. We propose that integrating routine cytometric genome size measurements into WGS and genome assembly pipelines will provide both a valuable assembly quality metric and contribute data for addressing fundamental evolutionary questions.

Two new species of lichenicolous Opegrapha are described from New Brunswick, Canada. Opegrapha inconspicua was found once on a rock bluff above a river on the thallus of Verrucaria aethiobola. It is characterized by punctiform, rounded, black ascomata 75–170 lm diam., an excipulum dark brown to black only in the upper part and (1–)2(–3)-septate ascospores of (12.5–)15.5–25 3 4–5 (–5.5) lm. Opegrapha parmeliiperda was found in four localities on epiphytic Parmelia squarrosa and P. sulcata. It is characterized by short lirelliform ascomata 70–220(–250)370–120 lm, in 6 loose groups of 5–15(–20) lirellae forming on black necrotic areas on the host thallus, 4-spored asci of 32–40 3 11–15 lm, and persistently hyaline and 3-septate ascospores of (11–)13–15.5(–17) 3 (3.5–)4–5(–5.5) lm. Opegrapha lamyi is reported for the first time in Canada, and O. anomea and O. sphaerophoricola for the first time in New Brunswick. One of only two previous reports of O. lamyi for the U.S.A. is based on a specimen from Colorado, revised here to Sclerococcum suburceolatum, the latter record representing a significant range extension for that species. Three of the five lichenicolous Opegrapha species reported here for New Brunswick are so far known in the province only in old mixedwood swamp-forests, highlighting the conservation significance of this forest community type. An identification key to the lichenicolous Opegrapha s.l. species known from Canada is provided. The worldwide diversity and host specificity of lichenicolous Opegrapha s.l. are discussed.

Climate change, land-use change, pollution and exploitation are among the main drivers of species’ population trends; however, their relative importance is much debated. We used a unique collection of over 1,000 local population time series in 22 communities across terrestrial, freshwater and marine realms within central Europe to compare the impacts of long-term temperature change and other environmental drivers from 1980 onwards. To disentangle different drivers, we related species’ population trends to species- and driver-specific attributes, such as temperature and habitat preference or pollution tolerance. We found a consistent impact of temperature change on the local abundances of terrestrial species. Populations of warm-dwelling species increased more than those of cold-dwelling species. In contrast, impacts of temperature change on aquatic species’ abundances were variable. Effects of temperature preference were more consistent in terrestrial communities than effects of habitat preference, suggesting that the impacts of temperature change have become widespread for recent changes in abundance within many terrestrial communities of central Europe.

We assessed soil fungal diversity at two sites on Deception Island, South Shetland Islands, Antarctica using DNA metabarcoding analysis. The first site was a relatively undisturbed area, and the second was much more heavily impacted by research and tourism. We detected 346 fungal amplicon sequence variants dominated by the phyla Ascomycota, Basidiomycota, Mortierellomycota and Chytridiomycota. We also detected taxa belonging to the rare phyla Mucoromycota and Rozellomycota, which have been difficult to detect in Antarctica by traditional isolation methods. Cladosporium sp., Pseudogymnoascus roseus, Leotiomycetes sp. 2, Penicillium sp., Mortierella sp. 1, Mortierella sp. 2, Pseudogymnoascus appendiculatus and Pseudogymnoascus sp. were the most dominant fungi. In addition, 440,153 of the total of 1,214,875 reads detected could be classified only at the level of Fungi. In both sampling areas the DNA of opportunistic, phytopathogenic and symbiotic fungi were detected, which might have been introduced by human activities, transported by birds or wind, and/or represent resident fungi not previously reported from Antarctica. Further long-term studies are required to elucidate how biological colonization in the island may be affected by climatic changes and/or other anthropogenic influences. [p. 4: ] "We also detected the presence of DNA of 11 lichenized fungi, of which five (Lecidea cancriformis, Psoroma tenue, Trimmatothelopsis smaragdula, Verrucaria alpicola and V. margacea) occurred in both sites."

Macaronesia is characterized by a high degree of endemism and represents a noteworthy system to study the evolutionary history of populations and species. Here, we compare the population-genetic structure in three lichen-forming fungi, the widespread Lobaria pulmonaria and two Macaronesian endemics, L. immixta and L. macaronesica, based on microsatellites. We utilize population genetic approaches to explore population subdivision and evolutionary history of these taxa on the Canary Islands, Madeira, Azores, and the western Iberian Peninsula. A common feature in all species was the deep divergence between populations on the Azores, a pattern expected by the large geographic distance among islands. For both endemic species, there was a major split between archipelagos. In contrast, in the widespread L. pulmonaria, divergent individuals were distributed across multiple archipelagos, suggesting a complex evolutionary history involving repeated migration between islands and mainland.

Central nervous system (CNS) diseases, including tumors such as glioblastomas and neurodegenerative diseases, such as Alzheimer’s disease, are some of the greatest challenges of modern medicine. Therefore, our study aimed to evaluate the anticancer and neuroprotective activity of the extract from a common European lichen Hypogymnia physodes and of its compound-physodic acid. The examined substances were cytotoxic against the glioblastoma cell lines A-172, T98G, and U-138 MG. Both substances strongly inhibited hyaluronidase, and diminished cyclooxygenase-2 activity (H. physodes extract), enzymes expressed in patients with malignant glioma. Furthermore, H. physodes extract inhibited tyrosinase activity, the enzyme linked to neurodegenerative diseases. The tested substances exhibited antioxidant activity, however, acetylcholinesterase and butyrylcholinesterase inhibitory activity were not high. We proved that physodic acid can cross the blood–brain barrier. We conclude that physodic acid and H. physodes extract should be regarded as promising agents with anticancer, chemopreventive, and neuroprotective activities, especially concerning CNS. : Lichen secondary metabolites are characterized by huge pharmacological potential. Our research focused on assessing the anticancer and neuroprotective activity of Hypogymnia physodes acetone extract (HP extract) and physodic acid, its major component. The antitumor properties were evaluated by cytotoxicity analysis using A-172, T98G, and U-138 MG glioblastoma cell lines and by hyaluronidase and cyclooxygenase-2 (COX-2) inhibition. The neuroprotective potential was examined using COX-2, tyrosinase, acetylcholinesterase (AChE), and butyrylcholinesterase (BChE) activity tests. Moreover, the antioxidant potential of the tested substances was examined, and the chemical composition of the extract was analyzed. For physodic acid, the permeability through the blood–brain barrier using Parallel Artificial Membrane Permeability Assay for the Blood–Brain Barrier assay (PAMPA-BBB) was assessed. Our study shows that the tested substances strongly inhibited glioblastoma cell proliferation and hyaluronidase activity. Besides, HP extract diminished COX-2 and tyrosinase activity. However, the AChE and BChE inhibitory activity of HP extract and physodic acid were mild. The examined substances exhibited strong antioxidant activity. Importantly, we proved that physodic acid crosses the blood–brain barrier. We conclude that physodic acid and H. physodes should be regarded as promising agents with anticancer, chemopreventive, and neuroprotective activities, especially regarding the central nervous system diseases.

Two corticolous species of Ramalina are described as new to science from China. Ramalina ailaoshanensis is described from Mt. Ailaoshan in southwest China. It is characterized by dichotomous narrow branches with sparse raised or tuberculate pseudocyphellae, without warts, absence of chrondroid tissue in the cortex, the tips of branchlets becoming thin, terete and curled backwards, and lacking soredia and isidia. Ramalina qinlingensis is described from Mt. Qinling in northwest China. It is characterized by broad branches with distinct pseudocyphellae, many warts and branchlets, the discontinuous chrondroid tissue in the cortex, and lacking soredia and isidia. Both species were recovered as monophyletic and well-supported in a maximum-likelihood phylogeny inferred from ITS sequence data. Kezwords: Asia, ITS, Lecanorales, molecular phylogeny, taxonomy.

Here, we describe the taxon hypothesis (TH) paradigm, which covers the construction, identification, and communication of taxa as datasets. Defining taxa as datasets of individuals and their traits will make taxon identification and most importantly communication of taxa precise and reproducible. This will allow datasets with standardized and atomized traits to be used digitally in identification pipelines and communicated through persistent identifiers. Such datasets are particularly useful in the context of formally undescribed or even physically undiscovered species if data such as sequences from samples of environmental DNA (eDNA) are available. Implementing the TH paradigm will to some extent remove the impediment to hastily discover and formally describe all extant species in that the TH paradigm allows discovery and communication of new species and other taxa also in the absence of formal descriptions. The TH datasets can be connected to a taxonomic backbone providing access to the vast information associated with the tree of life. In parallel to the description of the TH paradigm, we demonstrate how it is implemented in the UNITE digital taxon communication system. UNITE TH datasets include rich data on individuals and their rDNA ITS sequences. These datasets are equipped with digital object identifiers (DOI) that serve to fix their identity in our communication. All datasets are also connected to a GBIF taxonomic backbone. Researchers processing their eDNA samples using UNITE datasets will, thus, be able to publish their findings as taxon occurrences in the GBIF data portal. UNITE species hypothesis (species level THs) datasets are increasingly utilized in taxon identification pipelines and even formally undescribed species can be identified and communicated by using UNITE. The TH paradigm seeks to achieve unambiguous, unique, and traceable communication of taxa and their properties at any level of the tree of life. It offers a rapid way to discover and communicate undescribed species in identification pipelines and data portals before they are lost to the sixth mass extinction.

Despite the fascinating biology of lichens, such as the symbiotic association of lichenforming fungi (mycobiont) with their photosynthetic partners and their ability to grow in harsh habitats, lack of genetic tools manipulating mycobiont has hindered studies on genetic mechanisms underpinning lichen biology. Thus, we established an Agrobacterium tumefaciens-mediated transformation (ATMT) system for genetic transformation of a mycobiont isolated from Cladonia macilenta. A set of combinations of ATMT conditions, such as input biomass of mycobiont, co-cultivation period with Agrobacterium cells, and incubation temperature, were tested to identify an optimized ATMT condition for the C. macilenta mycobiont. As a result, more than 10 days of co-cultivation period and at least 2 mg of input biomass of the mycobiont were recommended for an efficient ATMT, owing to extremely slow growth rate of mycobionts in general. Moreover, we examined T-DNA copy number variation in a total of 180 transformants and found that 88% of the transformants had a single copy T-DNA insertion. To identify precise T-DNA insertion sites that interrupt gene function in C. macilenta, we performed TAIL-PCR analyses for selected transformants. A hypothetical gene encoding ankyrin repeats at its C-terminus was interrupted by T-DNA insertion in a transformant producing dark-brown colored pigment. Although the identification of the pigment awaits further investigation, this proof-of-concept study demonstrated the feasibility of use of ATMT in construction of a random T-DNA insertion mutant library in mycobionts for studying genetic mechanisms behind the lichen symbiosis, stress tolerance, and secondary metabolite biosynthesis. Keywords: Cladonia; lichen-forming fungi; Agrobacterium; ATMT; genetic transformation.

The botanical exploration of the Majella National Park has a long tradition dating back to the eighteenth century. However, the lichen biota of this area is still poorly investigated. To provide a baseline for future investigations, in this annotated checklist, we summarised all available information on the occurrence of lichens in the Majella National Park, retrieved from previous literature, herbarium material and original data produced by recent research. The checklist includes 342 infrageneric taxa. However, seven taxa are considered as dubious, thus setting the number of accepted taxa at 335, i.e. 45.8% of those currently known to occur in the Abruzzo Region. This checklist provides a baseline of the lichens known to occur in the Majella National Park, highlighting the potential of this area as a hotspot of lichen biodiversity, especially from a biogeographical point of view as indicated by the occurrence of several arctic-alpine species that form disjunct populations in the summit area of the massif.

Ten species of the lichen family Graphidaceae are treated in the ninth contribution to this series. Four species are new to science: Allographa cameroonensis Kalb & Schumm from Cameroon differs from A. grandis in having larger ascospores and in the lack of secondary lichen products. Allographa kuetchangiana Kalb & Schumm from Thailand differs from A. mexicana in having a permanent thalline cover of the ascomata and in having a whitish pruina on their top. Cruentotrema siamense Lücking & Kalb from Thailand differs from C. amazonum in having smaller ascomata and smaller ascospores. Ocellularia striata Kalb & Schumm from Thailand differs from O. jutaratiae in having smaller ascospores and in lacking the purplish, K+ greenish pigment which covers the remnants of the split proper exciple. Rhabdodiscus exutus (Hale) Kalb & Schumm is a new combination (Bas.: Ocellularia exuta Hale). Photographs of Allographa mexicana (Hale) Lücking & Kalb (including an isotype) show the variation of the ascomata and the differences to A. kuetchangiana. Allographa isidiata (Hale) Lücking & Kalb is reported from Ecuador, which is a new addition to the lichenobiota of this country and the second finding of this species after its description. Allographa plagiocarpa (Fée) Lücking & Kalb, before misidentified as A. mexicana, from Cartago Province is the second report of this species from Costa Rica. The chemistry of Ocellularia kohphanganensis Papong, Mangold & Lücking and the exact spelling of the specific epithet are corrected. Ocellularia macrocrocea Kalb is a new addition to the lichenobiota of Thailand where it is sometimes growing together with O. striata. The intraspecific variation of Ocellularia thelotremoides (Leight.) Hale ist discussed and the name is put on the correct place of the amended key to Thai Ocellularia species. Cochromatography of some Ocellularia species with a deep orange-yellow pigment together with a pure sample of skyrin in solvents A, B' and C showed identical Rf-values in all three solvent systems.

Eight species new to science are described, Allographa grandis from Cameroon which is distinguished by its very large ascomata, richly muriform, large ascospores and an inspersed hymenium (type B); Bapalmuia microspora from Malaysia which differs from B. consanguinea in having shorter and broader ascospores and a granular thallus; Diorygma cameroonense from Cameroon which differs from D. sticticum in having larger ascospores with more septa; Glyphis frischiana which is similar to G. atrofusca but differs in producing secondary lichen compounds, the first species in Glyphis in doing so. Two new species are added to the genus Heiomasia, viz. H. annamariae from Malaysia, which differs from H. sipmanii in producing the stictic acid aggr. and H. siamensis from Thailand, distinguished from H. sipmanii in containing hypoprotocetraric acid as a major metabolite. The published chemistry of several species of Heiomasia is revised and a new substance, heiomaseic acid, with relative Rf-values 5/19/8, is demonstrated for H. seaveyorum, H. siamensis and H. sipmanii. A world-wide key to the known species of Heiomasia is presented. Myriotrema squamiferum, a fertile species from Malaysia, is distinguished from M. frondosolucens by lacking lichexanthone. As there are conflicting literature data concerning Ocellularia crocea, the type specimen was investigated and the results are reported. Ocellularia macrocrocea, a related species from Malaysia, differs from O. rubropolydiscus in lacking the red pigment covering the disc of the ascomata and in having a broad stump-shaped columella. A revised chemistry for Ocellularia tanii, a new record for Sarawak, is also given. A table of Rfvalues and scans of relevant TLC runs facilitate the interpretation of the spots occurring on TLC plates of Graphidaceae.

Collema leptosporum was originally included in Collemataceae as part of the Collema fasciculare group, an informal group that also included C. fasciculare, C. papuanorum, and C. uviforme. However, molecular data from C. fasciculare showed that this species belongs to Arctomiaceae, and all species in this informal group were relocated to Arctomia, although no molecular data were generated and analyzed for C. leptosporum, C. papuanorum and C. uviforme. To investigate the phylogenetic relationships of Collema leptosporum, currently Arctomia leptospora, we analyzed three DNA loci and examined morphological and anatomical features of specimens collected near the type locality. Genetic data suggest that this species is not included in Arctomiaceae and should be treated as a new genus in Collemataceae. Hondaria gen. nov. is characterized by having the longest transversely-septate ascospores in the family ((100–)120–175(–200) × 2–4(–5) μm). This study also suggests that the structures characterizing the C. fasciculare group are a result of convergent evolution, since this group includes species from different distantly related species. Keywords: Arctomia leptospora, Collema leptosporum, C. fasciculare group, jelly lichens, South America biodiversity.

We describe the new lichenized fungus Lasioloma antillarum Lücking, Högnabba & Sipman from the Netherlands Antilles. The new species is characterized by a corticolous growth habit, apothecia with shortly tomentose margins, and rather small (35 – 50 × 12 – 16 μm), muriform ascospores in numbers of 2(– 4) per ascus. The material had originally been identified as Calopadia phyllogena (Müll. Arg.) Vězda, with associated sequence data, but in phylogenetic analyses consistently fell outside the latter genus. Its revised identification as a species of Lasioloma is consistent with its phylogenetic position and underlines the necessity of posterior annotations in public sequence repositories, in order to correct previous identifications. Key words: Antilles, Ascomycota, inaccuracies in GenBank, integrative taxonomy, Lasioloma, Pilocarpaceae, sequence labelling.

We investigated the association between air pollution and asthma and bronchitis hospital admissions in Algiers city (Algeria). In addition, we used geographic information systems (GIS) and statistical methods to evaluate their correlation with the atmospheric pollution estimated by the lichen biomonitoring method of the index of atmospheric purity (IAP), the index of human impact (IHI) and environmental parameters. Thus, we georeferenced 976 local patients (including 771 patients with asthma and 205 patients with bronchitis). Then, we compared the patients to the spatial distribution of IAP in thirty-five areas (communities). The results revealed a significant difference in the mean spatial variation in the diseases among those areas. In fact, maps and generalized linear models (GLMs) revealed a significant negative correlation between IAP and diseases. Therefore, redundancy analysis (RDA) and Monte Carlo tests described a significant effect of IAP, urbanization and the number of roads on the distribution of diseases. We hope our findings contribute to enriching the literature on health research with a low-cost method of monitoring outdoor air pollution.

Increasing gaseous emissions of nitrogen (N) and sulfur (S) associated with oil sands development in northern Alberta (Canada) has led to changing regional wet and dry N and S deposition regimes. We assessed the potential for using bog plant/lichen tissue chemistry (N and S concentrations, C:N and C:S ratios, in 10 plant/lichen species) to monitor changing atmospheric N and S deposition through sampling at five bog sites, 3–6 times per growing season from 2009 to 2016. During this 8-year period, oil sands N emissions steadily increased, while S emissions steadily decreased. We examined the following: (1) whether each species showed changes in tissue chemistry with increasing distance from the Syncrude and Suncor upgrader stacks (the two largest point sources of N and S emissions); (2) whether tissue chemistry changed over the 8 year period in ways that were consistent with increasing N and decreasing S emissions from oil sands facilities; and (3) whether tissue chemistry was correlated with growing season wet deposition of NH4 +-N, NO3 −-N, or SO4 2−-S. Based on these criteria, the best biomonitors of a changing N deposition regime were Evernia mesomorpha, Sphagnum fuscum, and Vaccinium oxycoccos. The best biomonitors of a changing S deposition regime were Evernia mesomorpha, Cladonia mitis, Sphagnum fuscum, Sphagnum capillifolium, Vaccinium oxycoccos, and Picea mariana. Changing N and S deposition regimes in the oil sands region appear to be influencing N and S cycling in what once were pristine ombrotrophic bogs, to the extent that these bogs may effectively monitor future spatial and temporal patterns of deposition.

We evaluated and compared the physiological and morphological response to pollution of two epiphytic lichen species, the foliose lichen Flavopunctelia praesignis and the fruticose lichen Usnea ceratina. Lichen samples were collected at remote areas and transplanted at different distances and directions from a paper industry in Morelia (Michoaca´n, Mexico). Lichen transplants were exposed for 4 months (1) around the industrial area and (2) in their native habitats (control sites). Changes of total chlorophyll content between samples before and after exposure, and morphological damage in the lichen thalli were investigated. Lichens showed species-specific responses. Flavopunctelia praesignis increased in total chlorophyll content after exposure around the industrial area and in control site. This suggests that total chlorophyll changes by a seasonal effect than pollution effect. On the other hand, chlorophyll content of U. ceratina did not change significantly after exposure. Bleaching, changes in color, deformations, and necrosis of lichen thalli were better visible in U. ceratina near the paper industry. We conclude that U. ceratina is a more pollution-sensitive species than F. praesignis. Morphological damage in the lichen thalli would be a suitable indicator for monitoring early biological effects of air pollution caused by the paper industry. Keywords: Air pollution, biomonitoring, photobiont, pollution damage, tropical region.

Analyses of data associated with 1376 taxonomic innovations (703 new taxa, 673 new combinations and replacement names) published from 2018–2020 are presented. Taxonomic contributions represented 14.2% of the published literature for the period. Most registration numbers for new names were obtained from MycoBank, suggesting the community has coalesced behind this resource. The overwhelming majority of new taxa (85.1%) and combinations (94.1%) involved crustose lichens and lichenicolous fungi. But lichenicolous fungi, regarded as a major source of undetected biodiversity, represented less than a fifth of innovations. More than half of new taxa were described from Asia and South America. Fewer than half (39%) of new taxa were published with molecular data, mostly from the ITS region but often in combination with data from additional loci. The majority of new taxa were based on small numbers of specimens (34.1% from one specimen, 69.2% from five or fewer) from few locations (44.4% from one location, 80.7% from five or fewer). Although a large number of identification keys were published, many new taxa were described with limited ecological data, distribution data or range maps, or discussion of similar species or phenotypic variation. Many innovations based on previously published names did not cite the nomenclatural type (67.7%) and less than a tenth of all such names were newly typified. Based on these results a best practices framework is presented. Keywords: Biodiversity hotspot, biogeography, conservation, data gaps, natural history collections, taxonomy, systematics.

Reichlingia americana, a new saxicolous species, is described from Oklahoma, U.S.A., representing the first records of the genus in North America. The species is distinguished from other members of the genus by a combination of its epilithic, rimose thallus; submuriform ascospores; presence of 2'-O-methylperlatolic acid; and unique habitat on sheltered sandstone faces. Distinctions from related species are discussed and a key to members of the genus is provided.

Aim: Phylogenetic diversification is a precursor to speciation, but the underlying patterns and processes are not well-studied in lichens. Here we investigate what factors drive diversification in two tropical, morphologically similar macrolichens that occupy a similar range but differ in altitudinal and habitat preferences, testing for isolation by distance (IBD), environment (IBE), and fragmentation (IBF). Location: Neotropics, Hawaii, Macaronesia. Taxon: Sticta andina, S. scabrosa (Peltigeraceae). Methods: We analysed 395 specimens from 135 localities, using the fungal ITS barcoding marker to assess phylogenetic diversification, through maximum likelihood tree reconstruction, TCS haplotype networks, and Tajima's D. Mantel tests were employed to detect structure in genetic vs. geographic, environmental, and fragmentation distances. Habitat preferences were quantitatively assessed by statistical analysis of locality-based BIOclim variables. Results: Sticta andina exhibited high phenotypic variation and reticulate phylogenetic diversity across its range, whereas the phenotypically uniform S. scabrosa contained two main haplotypes, one unique to Hawaii. Sticta andina is restricted to well-preserved andine forests and paramos, naturally fragmented habitats due to disruptive topology, whereas S. scabrosa thrives in lowland to lower montane zones in exposed or disturbed microsites, representing a continuous habitat. Sticta scabrosa showed IBD only across its full range (separating the Hawaiian population) but not within continental Central and South America, there exhibiting a negative Tajima's D. Sticta andina did not exhibit IBD but IBE at continental level and IBF in the northern Andes. Main conclusions: Autecology, particularly preference for either low or high altitudes, indirectly drives phylogenetic diversification. Low diversification in the low altitude species, S. scabrosa, can be attributed to rapid expansion and effective gene flow across a more or less continuous niche due to disturbance tolerance. In contract, high diversification in the high altitude species, S. andina, can be explained by niche differentiation (IBE) and fragmentation (IBF) caused by the Andean uplift.

Lichens occupy diverse substrates across tremendous ranges of environmental variation. In boreal forests, lichen communities co-occur in ‘strata’ defined by terrestrial or arboreal substrates, but these strata may or may not be interchangeable as bioindicators. Do co-occurring lichen strata have similar community structures and environmental responses? Could one stratum serve as a proxy for the other? We assessed variation in species richness and community compositions between ground-layer versus epiphyte-layer lichen strata in boreal forests and peatlands of interior Alaska. Species richness was lower and more spatially structured in the ground layer than the epiphyte layer. Richness of strata was not correlated. The most compositionally unique ground-layer communities were species-poor but contained regionally rare species not common in other plots. Variation in community compositions (ordination scores) were not congruent between strata (Procrustes congruence < 0.16 on 0–1 scale); the largest departures from congruence occurred where ground layers were species-poor. The best predictors of ground-layer community compositions were hydrological and topographic, whereas epiphytes were most associated with macroclimate and tree abundances. We conclude that lichens on different substrates ‘move in different circles’: compositional gradients did not agree and the environmental gradients most important to each lichen stratum were not the same. The conditions which strongly influence one vegetation stratum may have little bearing upon another. As global changes modify habitats, an incremental change in environment may lead community trajectories to diverge among lichen strata

There is growing evidence that species and communities are responding to, and will continue to be affected by, climate change. For species at risk, vulnerability can be reduced by ensuring that their habitat is extensive, connected and provides opportunities for dispersal and/or gene flow, facilitating a biological response through migration or adaptation. For woodland epiphytes, vulnerability might also be reduced by ensuring sufficient habitat heterogeneity, so that microhabitats provide suitable local microclimates, even as the larger scale climate continues to change (i.e. microrefugia). This study used fuzzy set ordination to compare bryophyte and lichen epiphyte community composition to a large-scale gradient from an oceanic to a relatively more continental macroclimate. The residuals from this relationship identified microhabitats in which species composition reflected a climate that was more oceanic or more continental than would be expected given the prevailing macroclimate. Comparing these residuals to features that operate at different scales to create the microclimate (landscape, stand and tree-scale), it was possible to identify how one might engineer microrefugia into existing or new woodland, in order to reduce epiphyte vulnerability to climate change. Multimodel inference was used to identify the most important features for consideration, which included local effects such as height on the bole, angle of bole lean and bark water holding capacity, as well as tree species and tree age, and within the landscape, topographic wetness and physical exposure

The taxonomy of the genus Sticta in Hawaii is reassessed, based on a separately published molecular phylogeny using the fungal barcoding marker ITS. Based on Magnusson and Zahlbruckner's treatment from 1943 and Magnusson's catalogue from 1955, seven species of Sticta and three infraspecific taxa had been reported from the archipelago, all widespread except the putative endemic S. plumbicolor. Here we provide a taxonomic treatment of 13 taxa, 12 species and one subspecies, distinguished in a previous phylogenetic analysis: S. acyphellata, S. andina, S. antoniana, S. emmanueliana, S. flynnii, S. fuliginosa, S. hawaiiensis, S. limbata, S. plumbicolor, S. scabrosa subsp. hawaiiensis, S. smithii, S. tomentosa and S. waikamoi. All taxa are described, discussed and illustrated and a dichotomous key is presented. The implications of revised species taxonomies for studies in other fields such as ecology, ecophysiology, biogeography, biochemistry, and applications such as environmental monitoring are discussed. We also propose a protocol to use Sticta lichens to monitor the environmental health of Hawaiian ecosystems

The lichenicolous ‘heterobasidiomycetes’ belong in the Tremellomycetes (Agaricomycotina) and in the Pucciniomycotina. In this paper, we provide an introduction and review of these lichenicolous taxa, focusing on recent studies and novelties of their classification, phylogeny and evolution. Lichen-inhabiting fungi in the Pucciniomycotina are represented by only a small number of species included in the genera Chionosphaera, Cyphobasidium and Lichenozyma. The phylogenetic position of the lichenicolous representatives of Chionosphaera has, however, never been investigated by molecular methods. Phylogenetic analyses using the nuclear SSU, ITS, and LSU ribosomal DNA markers reveal that the lichenicolous members of Chionosphaera form a monophyletic group in the Pucciniomycotina, distinct from Chionosphaera and outside the Chionosphaeraceae. The new genus Crittendenia is described to accommodate these lichen-inhabiting species. Crittendenia is characterized by minute synnemata-like basidiomata, the presence of clamp connections and aseptate tubular basidia from which 4–7 spores discharge passively, often in groups. Crittendenia, Cyphobasidium and Lichenozyma are the only lichenicolous lineages known so far in the Pucciniomycotina, whereas Chionosphaera does not include any lichenicolous taxa

The lichen genus Lecanactis Körb. in Tasmania comprises six species: L. abietina (Ach.) Körb., which is widespread and pan-temperate; L. latispora Egea & Torrente and L. neozelandica Egea & Torrente, both shared with New Zealand and with the former recorded here from the Auckland Islands for the first time; L. mollis (Stirt.) Frisch & Ertz, shared with Victoria and New Zealand; L. aff. dilleniana (Ach.) Körb., a European species recorded provisionally for Tasmania on the basis of several sterile collections; L. scopulicola Kantvilas, which is described here as new to science and apparently a Tasmanian endemic. This new taxon occurs in rocky underhangs and is characterized by a thick, leprose thallus containing schizopeltic acid, and 3-septate ascospores, 19–30 × 4.5–6 μm. Short descriptions and a discussion of distribution and ecology are given for all species. A key for all 11 Australian species of the genus is provided, including L. subfarinosa (C. Knight) Hellb. and L. tibelliana Egea & Torrente, which are recorded for Australia for the first time, and L. platygraphoides (Müll.Arg.) Zahlbr., a first record for New South Wales. Lecanactis spermatospora Egea & Torrente and L. sulphurea Egea & Torrente are also included

The genus Micarea was studied for the first time in the Taita Hills, Kenya. Based on new collections and existing data, we reconstructed a phylogeny using ITS, mtSSU and Mcm7 regions, and generated a total of 27 new sequences. Data were analyzed using maximum likelihood and maximum parsimony methods. Based mainly on new collections, we discovered four undescribed well-supported lineages, characterized by molecular and phenotypic features. These lineages are described here as Micarea pumila, M. stellaris, M. taitensis and M. versicolor. Micarea pumila is characterized by a minutely granular thallus, small cream-white or pale brownish apothecia, small ascospores and the production of prasinic acid. Micarea stellaris has a warted-areolate thallus, cream-white apothecia usually darker at the centre, a hymenium of light grey or brownish pigment that dissolves in K, and intense crystalline granules that appear as a belt-like continuum across the lower hymenium when studied in polarized light. Micarea taitensis is characterized by a warted-areolate thallus and cream-white or yellowish apothecia that sometimes produce the Sedifolia-grey pigment. Micarea versicolor is characterized by a warted-areolate, sometimes partly granular thallus and apothecia varying from cream-white to light grey to blackish in colour. This considerable variation in the coloration of its apothecia is caused by an occasional mixture of the Sedifolia-grey pigment in the epihymenium and another purplish brown pigment in the hymenium. Micarea stellaris, M. taitensis and M. versicolor produce methoxymicareic acid. The main distinguishing characters are presented in a species synopsis. Three of the new species are nested in the M. prasina group, and the fourth one (M. taitensis) resolves as a basal taxon to the M. prasina group. The new species inhabit montane cloud forests, which have fragmented dramatically throughout the Eastern Arc Mountains in recent decades

Lecanora s. lat. is a genus of crustose, rarely placodioid lichens comprising c. 1000 recognized species and subdivided into several morphology-based groups. Some of these groups have been supported in phylogenetic analyses and segregated as new genera. One of the remaining groups that has not been previously studied by molecular methods in much detail, the L. saligna-group, includes corticolous and lignicolous crustose lichens, usually containing isousnic or usnic acid (or both) as major secondary metabolites. As part of our ongoing project ‘Lecanomics’, a phylogenetic analysis based on two loci was conducted and found the L. saligna-group to be divided into two main clades and several well-supported minor clades. The L. varia clade, chosen as one of the outgroups, emerged within the L. saligna-group. The majority of the clades are characterized by phenotypic differences. However, several well-supported clades share similarities with their sister groups, suggesting that species circumscriptions based solely on phenotypic characters may be too conservative to characterize the true species diversity present within the group. Also, there is evidence for some geographical separation of lineages; for example, most North American individuals, previously known as Lecanora saligna and L. albellula, form two clades separate from their European namesakes and are here preliminarily called ‘Lecanora sp. B’, ‘Lecanora sp. C’ and ‘Lecanora sp. D’. However, L. saligna and L. albellula also appear to occur in North America, and some specimens from the Caucasus and Iran cluster within the North American clades. Lecanora anopta and L. subravida are reported for the first time from Iran

The genus Thelopsis was classified in the family Stictidaceae but its systematic position has never been investigated by molecular methods. In order to determine its family placement and to test its monophyly, fungal DNA of recent collections of Thelopsis specimens was sequenced. Phylogenetic analyses using nuLSU, RPB2 and mtSSU sequences reveal that members of Thelopsis form a monophyletic group within the genus Gyalecta as currently accepted. The placement of Thelopsis, including the generic type T. rubella, within the genus Gyalecta challenges the generic circumscription of this group because Thelopsis is well recognized by the combination of morphological characters: perithecioid ascomata, well-developed periphysoids, polysporous asci and small, few-septate ellipsoid-oblong ascospores. The sterile sorediate Opegrapha corticola is also placed in the Gyalectaceae as sister species to Thelopsis byssoidea + T. rubella. Ascomata of O. corticola are illustrated for the first time and support its placement in the genus Thelopsis. The hypothesis that O. corticola might represent the sorediate fertile morph of T. rubella is not confirmed because the species is phylogenetically and morphologically distinct. Thelopsis is recovered as polyphyletic, with T. melathelia being placed as sister species to Ramonia. The new combinations Thelopsis corticola (Coppins & P. James) Sanderson & Ertz comb. nov. and Ramonia melathelia (Nyl.) Ertz comb. nov. are introduced and a new species of Gyalecta, G. amsterdamensis Ertz, is described from Amsterdam and Saint-Paul Islands, characterized by a sterile thallus with discrete soralia. Petractis luetkemuelleri and P. nodispora are accommodated in the new genus Neopetractis, differing from the generic type (P. clausa) by having a different phylogenetic position and a different photobiont. Francisrosea bicolor Ertz & Sanderson gen. & sp. nov. is described for a sterile sorediate lichen somewhat similar to Opegrapha corticola but having an isolated phylogenetic position as sister to a clade including Gyalidea praetermissa and the genera Neopetractis and Ramonia. Gyalecta farlowii, G. nidarosiensis and G. carneola are placed in a molecular phylogeny for the first time. The taxonomic significance of morphological characters in Gyalectaceae is discussed

An examination of collections from Japan has increased the number of Brianaria and Micarea species known from that country from eight to 19, including one new species, M. rubioides Coppins (also from Malaysia and the Philippines). Eleven species are reported as new to Japan (M. botryoides (Nyl.) Coppins, M. denigrata (Fr.) Hedl., M. erratica (Körb.) Hertel et al., M. hedlundii Coppins, M. lithinella (Nyl.) Hedl., M. micrococca (Körb.) Gams ex Coppins and M. misella (Nyl.) Hedl.) or new to Asia: M. byssacea (Th. Fr.) Czarnota et al., M. deminuta Coppins and M. xanthonica Coppins & Tønsberg (new to Asia; Japan); M. nitschkeana (J. Lahm ex Rabenh.) Harm. (new to Asia; South Korea). The presence of Micarea prasina s. str. from Japan needs to be confirmed; no collection was found in this study. Additional collections from South Korea and Sri Lanka are also reported, including the new species M. ceylanica Coppins from Sri Lanka. The identity of M. synotheoides (Nyl.) Coppins, originally described from Japan, has been resolved, resulting in the renaming of Western European material, previously under that name, as M. longispora Coppins. Micarea coreana Lőkös et al. is reported here as a synonym of M. erratica. The type of Lecidea inopinula Nyl. requires the new combination Micarea inopinula (Nyl.) Coppins & T. Sprib. to replace Micarea prasinella (Jatta) I. M. Lamb

Lichens often grow in microhabitats where they are exposed to severe abiotic stresses such as desiccation and temperature extremes. They are also often exposed to levels of light that are greater than lichen photobionts can use in carbon fixation. Unless regulated, excess energy absorbed by the photobionts can convert ground state oxygen to reactive oxygen species (ROS). These ROS can attack the photosynthetic apparatus, causing photoinhibition and photo-oxidative stress, reducing the ability of the photobionts to fix carbon. Here, we outline our current understanding of the effects of high light on lichens and the mechanisms they use to mitigate or tolerate this stress in hydrated and desiccated states. Tolerance to high light can be achieved first by lowering ROS formation, via synthesizing light screening pigments or by thermally dissipating the excess light energy absorbed; second, by scavenging ROS once formed; or third, by repairing ROS-induced damage. While the primary focus of this review is tolerance to high light in lichen photobionts, our knowledge is rather fragmentary, and therefore we also include recent findings in free-living relatives to stimulate new lines of research in the study of high light tolerance in lichens

Peter D. Crittenden served as senior editor of The Lichenologist, the flagship journal in the field of lichenological research, for a period of two decades, between 2000 and 2019. A review of the development of the journal and the publication output during this period is provided. The number of papers published during this period (1197) matches that of all papers published under the three previous senior editors, Peter W. James, David L. Hawksworth and Dennis H. Brown, during a much longer period of 42 years from 1958 to 1999. Peter oversaw important editorial changes to the layout and content of the journal: an increased size with a modern cover design, leaving behind the classic mint-coloured cover of more than 40 years; the addition of ‘thematic issues’ and encouragement of large monographs; implementation of substantial changes to the Code, such as effective electronic publication and obligate registration of new fungal names; and more recently a new policy to reject so-called ‘single naked species descriptions’. Shortly before Peter took over as senior editor, The Lichenologist had received its first impact factor, and Peter managed to continuously increase this measure from around 0.9 to lately up to over 1.5, higher than most other competing journals. The 1197 papers between 2000 and 2019 were published by a total of 1138 different authors, more than half of whom appeared just once as author, whereas a small number participated in numerous (up to 93) papers. There was a continuous increase in the mean number of authors per paper per year, from below 2.5 to around 3.5, the highest numbers ranging between 11 and 30; still, c. 75% of all papers between 2000 and 2019 were single- authored or had up to three authors. Based on affiliations at the time of publication, two thirds of author contributions came from Europe (66%), 13% from North America, 9% from Asia and 7% from Latin America. Likewise, almost half of the study areas were located in Europe and around 10% each in North America, South America and Asia. The countries with the highest number of studies included, in descending order, the United States, Spain, the United Kingdom, Norway and Sweden. North America and Europe were over-represented in terms of author contribu- tions, whereas Africa, Latin America, Australia and Oceania were over-represented in terms of study areas. The 1197 papers analyzed encom- passed a broad diversity of topics, classified into 32 categories. Taxonomy of lichenized fungi was the most frequent component, representing the focal point in almost half of all studies, followed by phylogeny and evolution, ecology, and the taxonomy of lichenicolous fungi. Around two thirds of the currently accepted genera of lichenized fungi were treated, with a significant correlation between known species richness and the number of papers in which a genus was treated, underlining the taxonomic representativity of papers published in the journal during the past two decades. Examples of genera that were treated more frequently than expected included commonly studied model organisms, such as Lobaria, and those frequently featured in ecological or other non-taxonomic studies, such as Xanthoria. Species-rich tropical genera, particularly in the Graphidaceae, were generally under-represented. Mean number of authors per paper per volume and total number of country origins of authors per volume were the best predictors of impact factor, followed by diversity of study countries per volume, mean number of study countries per paper per volume, mean number of topics per paper per volume, and proportion of studies with phylogenetic components per volume. Individual papers that contributed to high impact factors included broad-scale revisionary treatments and worldwide keys to spe- cies-rich taxa, substantial phylogenetic reclassifications of known taxonomic groups, papers dealing with novel methodological approaches of broad interest, and broad-scale studies related to environmental change and lichen biomonitoring.

This first issue of The Lichenologist Volume 53 (2021) is dedicated to Peter Crittenden, in recognition of his long years of service to the journal, the British Lichen Society and lichenology worldwide. With Volume 52 (2020), Peter handed the responsibilities of Senior Editor to his successors, Leena Myllys and Christopher Ellis. On completing this transition there was universal assent among the associate editors who had served with Peter, and close friends, that the depth of gratitude felt for Peter’s work should be expressed in a Special Issue, bringing together a series of papers on a wide breadth of subjects.

Reindeer lichens from the genus Cladonia and snow lichens from the genus Stereocaulon are components of spruce lichen wood- land, which is one of the most extensive ecosystems in Eastern Canada (Payette & Delwaide 2018). Unlike reindeer lichens, Stereocaulon species have a mutualistic association with cyanobac- teria, mainly from the genus Stigonema, which are located in cephalodia (Huss-Danell 1977, 1979; Kershaw 1978; Kytöviita & Crittenden 2002; Lavoie et al. 2020). In Canada, acetylene reduc- tion assays on Stereocaulon cyanobacteria have demonstrated their critical contribution to the nitrogen (N) budget (Crittenden & Kershaw 1978; Kershaw 1978). Cyanobacteria use the nitrogenase enzymatic complex to reduce atmospheric N2 into bioavailable ammonium. Thus, understanding the biology and efficacy of the nitrogenase, which reduces atmospheric N2 into bioavailable ammonium, is crucial to obtaining a clearer pic- ture of nutrient flow in boreal forests

Epiphytic lichens are sensitive to deteriorating air quality, but levels of nitrogen and especially sulphur deposition have been in decline over most of Europe in recent decades. We assessed the response of epiphytic lichens to this decline, using data from long-term monitoring sites in Sweden. We analyzed 20 years of data to investigate temporal trends in lichen communities’ sensitivity to sulphur, nitrogen preference, species richness and alpha and beta diversity. We found only limited and partial evidence of recovery in the area that previously had high levels of deposition, and a decline in mean sulphur sensitivity at a northern site with low deposition levels throughout the monitoring period. The slow recolonization of sensitive species, even where environmental conditions are now suitable, is probably a result of impoverished regional species pools and the inherent limited dispersal capacity of many lichen species. We suggest due consideration of these factors in the use of epiphytic lichens as environmental indicators in a period of improving air quality

A new lichen species is described from specimens growing on Fraxinus trees north of Eindhoven (the Netherlands). Morphological and genetic studies suggest that the new species belongs in the genus Catillaria, and the name Catillaria flexuosa is proposed because of its flexuose apothecia. The new species is characterized by the relatively large apothecia (up to 0.9 mm diam.) and relatively thick, knobby to ±subsquamulose, greenish, thallus. Due to their similar morphological features, C. flexuosa can be easily confused with Catillaria chalybeia, C. fungoides or C. nigroclavata, so it is therefore compared with these species. In addition, Arthonia epiphyscia is reported being a very rare species in the Netherlands

The cortex is composed of interlocking cells shaped like jigsaw puzzle pieces. Spores are hyaline, 1-septate, 25–40(–50) × 6.5–9(–11) μm. Maximum likelihood phylogenetic analyses on multilocus data sets, first spanning the entire order Peltigerales and then restricted to Peltigeraceae with extended sampling from Solorina and Peltigera, revealed the placement of Sinuicella outside of currently recognized genera, sister to Peltigera, with high support. Based on the phylogenetic, morphological and ecological distinctness of Sinuicella, we formally introduce a new genus represented by the single species S. denisonii. The cyanobiont of S. denisonii is Nostoc from phylogroup XL, Clade 2, Subclade 3 based on the rbcLX marker

In recent years, several species that have long been considered to belong in Bacidia s. lat. have been transferred to other genera such as Bellicidia, Bibbya, Scutula, and also to Toniniopsis, accommodating species previously placed in Bacidia and Toninia. One of its widespread species, Toniniopsis subincompta, can be recognized by its thinly granular thallus, dark brown to black apothecia, green epithecium, red-brown hypothecium, and bacilliform ascospores. However, it shows considerable variation in thallus structure, and coloration of apothecia, hypothecium and exciple. We sequenced 20 specimens of T. subincompta to investigate whether there is phylogenetic support for the delimitation of species in accordance with the variability of the observed characters. For phylogenetic analyses, we used newly generated sequence data from the nuclear internal transcribed spacer (nrITS), mitochondrial small subunit (mtSSU) and DNA-directed RNA polymerase II subunit (RPB2). Maximum likelihood and Bayesian inference analyses, as well as three species delimitation programs, provided consistent evidence that T. subincompta forms two separate lineages, to be recognized at the species level. The complex nomenclature of T. subincompta (basionym Lecidea subincompta) shows it to be a synonym of Bellicidia incompta. For the most common taxon previously called Bacidia (Toniniopsis) subincompta, the new combination T. separabilis is made, rather than proposing a conserved type for Lecidea subincompta. Toniniopsis dissimilis is newly described to accommodate the less common taxon. Toniniopsis dissimilis is characterized by a predominantly wrinkled to warted to subsquamulose thallus; generally grey-brown to dark brown apothecia, often with a lighter margin; a dark brown hypothecium, frequently gradually merging into the coloration of the exciple below and the lateral part of the exciple attached to the hymenium; a mostly colourless rim and lateral part of the exciple. The closely related T. separabilis is characterized by a thallus of mostly single or contiguous ±loose granules, often forming short, coralloid, isidium-like bulges; darker apothecia, with a margin mostly of the same colour or darker than the disc; a comparatively thinner hypothecium easily separated from the exciple below. The rim and lateral part of the exciple often contain either a blue, brown or mixed blue-brown colour in the upper part or along the whole margin. Lectotypes of Bacidia vegeta, Lecidea bacillifera f. melanotica and Secoliga atrosanguinea var. affinis (the synonyms of T. separabilis) are selected. Cyanotrophy and the occurrence of albino morphs in T. separabilis are discussed.

Three species of lichenicolous Opegrapha s. lat. are newly described, all apparently host-specific at genus level. Opegrapha arthoniicola Coppins & S. Y. Kondr. is described from western Britain and Ireland, where it grows on the thallus of Arthonia radiata on Corylus bark; it has small clustered ascomata, asci that are usually 6-spored and rather small ascospores (10.5–)12.5–14.5 μm in length. Opegrapha sawyeriana Coppins occurs on the thallus of Coniocarpon cinnabarinum, also on Corylus bark, from oceanic western parts of Scotland, Ireland and southern England; in comparison to O. arthoniicola it has smaller, often scattered ascomata with a pigmented basal layer, 8-spored asci and slightly larger ascospores 13–14.5(–16) μm in length. Opegrapha hochstetteri Coppins has been found on thalli of Verrucaria hochstetteri and V. muralis on calcareous rocks and stonework in southern England and Luxembourg; collections were formerly identified as Opegrapha rupestris Pers. but it differs from this species by narrower ascomata with a persistent narrow slit, normally 6- rather than 8-spored asci and ascospores with pigmentation in the spore wall rather than the perispore. Lifted from synonymy is Opegrapha opaca Nyl., which inhabits the thallus of Verrucaria nigrescens and V. viridula on calcareous rocks and stonework, and is so far recorded from southern England, Luxembourg, France, northern Spain and Israel. The hosts of the European species of lichenicolous Opegrapha on Verrucaria s. lat. on calcareous rocks (O. hochstetteri, O. opaca and O. rupestris) belong to different phylogenetic lineages within the Verrucariaceae. A key is also provided to the lichenicolous species of Opegraphaceae currently known from Great Britain and Ireland.

Usnea esperantiana is reported as new to Asia. It was collected from Taiwan where it grew on coniferous and broad-leaf trees at elevations between 1716 and 2580 m. The ITS rDNA sequences of Taiwanese and European materials of U. esperantiana form a monophyletic clade within the already reported clade consisting of U. cornuta and the related taxa. Although two distinct clades were formed in the U. esperantiana clade, no morphological and chemical differences were found between them.

chapter in book; About 890 species of lichen-forming fungi and more than 30 species of calicioid fungi in the Mycocaliciales are known in the Atlantic Maritime Ecozone of eastern Canada. Based on comparisons with better-studied European lichen biotas, it is estimated that about 25% of the species occurring in the ecozone have yet to be documented. Lichenicolous fungi other than calicioid species remain poorly known, and there has been little focus on the algal and cyanobacterial components of lichen diversity. The historical and global contexts of the biota are reviewed, and patterns of disjunction noted. Climatic variation and associated vegetation gradients across the ecozone are described, and a preliminary categorization is provided of patterns of lichen distribution within this context. It is concluded that the ranges of lichens in the Atlantic Maritime Ecozone are more nearly in a state of equilibrium with prevailing climatic conditions than are those of vascular plants. The rarity of adventive species is inferred to be mainly a consequence of the efficient past and present dispersal of most lichens. While considerable scope remains for increasing knowledge of diversity and distributions, there is also a need for research on the community structure and composition, habitat and substrate ecology, life histories, and most urgently, the conservation of the lichen biota. The Atlantic Maritime Ecozone is an important refuge for many lichens that have undergone sharp declines in neighbouring regions, owing to habitat loss, air pollution, and other human impacts.

Cladonia krogiana, previously known only from Norway and the Czech Republic, is reported here for North America from two localities near the Bay of Fundy, New Brunswick, Canada. It occurs there on open, rocky banks of clear, free-flowing rivers, habitats similar to those in which it has been found in Norway. We also document the occurrence of C. rangiformis in North America, based on collections from two localities on the southwest coast of Conception Bay, on the Avalon Peninsula of the island of Newfoundland, Canada. It is possibly an accidental, but naturalized, introduction in this area, where European settlement began in the early 1600s. A molecular phylogenetic analysis confirmed the identity of one of the Newfoundland specimens. The IGS rDNA haplotype to which it belongs is the same as the most widely distributed haplotype of C. rangiformis in Europe and Macaronesia. Previous reports of C. rangiformis for continental North America are based on misidentifications. A 19th century collection reportedly made on the island of Bermuda, while correctly identified, is of uncertain provenance.

Vascular plants and lichens often produce a diversity of carbon‐based secondary compounds (CBSCs) to protect them against biotic and abiotic stresses. These compounds play important but often compound‐specific roles in community and ecosystem processes by affecting herbivore and decomposer activity. However, our understanding of what drives community‐level CBSCs among ecosystems or across environmental gradients is limited. We measured concentrations and compositions of CBSCs for all dominant vascular plant and lichen species present across a 500‐m alpine elevational gradient. These measurements were combined with data on species composition and abundance to obtain whole‐community measures of plant and lichen CBSCs across the gradient. At the whole community level, plant CBSCs had the lowest concentrations while lichen CBSCs had the highest concentrations at the highest elevations. Further, plant CBCSs shifted from those associated with herbivore defence towards those protecting against light and oxidative stress as elevation increased, while lichen CBSCs showed the opposite pattern. Synthesis. Our findings that individual compounds show contrasting responses to the same environmental gradient highlight the importance of studying qualitative as well as quantitative changes in CBSCs. Further, the divergent responses between vascular plants and lichens reveal that in systems where both groups are abundant, they need to be considered simultaneously to better understand how future environmental changes may impact on ecosystem‐level processes.

Biocrusts are key drivers of ecosystem functioning in drylands, yet our understanding of how climate change will affect the chemistry of biocrust-forming species and their impacts on carbon (C) and nitrogen (N) cycling is still very limited. Using a manipulative experiment conducted with common biocrust-forming lichens with distinct morphology and chemistry (Buellia zoharyi, Diploschistes diacapsis, Psora decipiens and Squamarina lentigera), we evaluated changes in lichen total and isotopic C and N and several soil C and N variables after 50 months of simulated warming and rainfall reduction. Climate change treatments reduced δ13C and the C : N ratio in B. zoharyi, and increased δ15N in S. lentigera. Lichens had species-specific effects on soil dissolved organic N (DON), NHþ 4 , β-glucosidase and acid phosphatase activity regardless of climate change treatments, while these treatments changed how lichens affected several soil properties regardless of biocrust species. Changes in thallus δ13C, N and C : N drove species-specific effects on dissolved organic nitrogen (DON), NHþ 4 , β-glucosidase and acid phosphatase activity. Our findings indicate that warmer and drier conditions will alter the chemistry of biocrustforming lichens, affecting soil nutrient cycling, and emphasize their key role as modulators of climate change impacts in dryland soils.

The phenolic composition and antioxidant capacity of four Tunisian lichen species, Cladonia rangiformis,Flavoparmelia caperata, Squamarina cartilaginea and Xanthoria parietina, were determined in order to provide abetter understanding of their lichenochemical composition. Powdered material of F. caperata was the richest intotal phenolic content (956.68 g GAE g 1DW) and S. cartilaginea in proanthocyanidin content (77.31 g CE g 1DW), while the acetone extract of X. parietina showed the highest flavonoid content (9.56 g CE g 1DW). Theantioxidant capacity of all lichen extracts and crude material was evaluated by DPPH*scavenging, iron-chelating,and iron-reducing powers. Results showed that methanol extracts of S. cartilaginea had the highest DPPH*antioxidant capacity (IC50=0.9 gmL 1) and the highest iron-reducing power was attributed to the acetoneextract of this species. All extracts of all species were further screened by Fourier-transform infrared spectroscopy(FT-IR) and nuclear resonance spectroscopy (NMR); results showed an abundance of phenols, aromaticcompounds, and fatty acids. Overall, our results showed that the investigated species are a rich source ofpotentially bioactive compounds with valuable properties.Keywords: DPPH*, FT-IR, NMR, QUENCHER, lichenized fungi.

Abstract; Lichen desiccation/rehydration cycles lead to an increased oxidative stress modulated by the multifaceted mediator nitrogen monoxide (NO). Active cell death, frequently triggered by oxidative damage with NO participation, has been confirmed even in unicellular organisms. This adaptive mechanism has not been studied in lichens and no specific experimental protocols exist. Hoechst 33342 enters viable cells and DNA binding increases its fluorescence, particularly intense in condensed apoptotic chromatin. YO-PRO-1 can only permeate the altered membrane of apoptotic P2X7-positive cells. Proteolytic caspases are activated upon different types of active cell death. Our objectives are to determine if these markers indicate active cell death in Ramalina farinacea after desiccation/rehydration and to study the effect of NO scavenging. YO-PRO-1, Hoechst 33342 and Caspase 3/7 Green DNA binding were assessed in thalli rehydrated with deionized water and with a cocktail of apoptosis inducers. A 24 h kinetics and a microscopical analysis were performed. YO-PRO-1 fluorescence was not detected, Hoechst 33342 staining abruptly decreases during the first hours, while caspase-like activity associated to phycobionts steadily increases. Whereas the apoptosis inducers cocktail 1x significantly increased caspase-like activity affecting both symbionts, Hoechst staining was only affected at 10x. NO scavenging diminishes caspase-like activation and seems to accelerate Hoechst abrupt decrease during thallus rehydration. In conclusion, the demonstration of caspase-like activity in R. farinacea and its Trebouxia phycobionts point to the presence of active cell death but other methods assessing cell effective death or DNA irreversible fragmentation (i.e. TUNEL assay) are necessary to confirm this feature.

Global warming coupled with increased drought is predicted to have a significant negative impact on desert ecosystems. In arid desert regions, a large proportion of the ground surface is covered by specialized organisms such as mosses and lichens that form biocrusts, which play a vital role in ecosystems. However, the long-term effects of warming and drought on these key biotic components of desert ecosystems remain poorly understood. Using a manipulative experiment conducted for 12 years in the Tengger Desert, northwestern China, we evaluated how both mosses and lichens in biocrust communities responded to 0.5°C and 1.5°C increases in temperature coupled with 5% and 8% reductions in total annual precipitation, respectively, using two groups of open-top chambers to approximate climate change conditions that are predicted to occur in this study region. Furthermore, surface soil carbon uptake by the biocrusts was also evaluated. Twelve years of warming coupled with increased drought resulted in a significant decrease in the cover and biomass of mosses but did not change the cover or biomass of lichens. These changes in the mosses were positively correlated with the duration and intensity of the treatments. Warming coupled with reduced precipitation significantly reduced the carbon uptake of the moss-dominated biocrusts by reducing the availability of moisture content. However, lichen carbon uptake was insensitive to the warming and reduced precipitation treatments. The reduction in cover and biomass of moss-dominated biocrusts might be attributed to large amounts of carbon loss, which further alters biocrust multifunctionality in desert ecosystems. In addition, our findings suggest that coupled warming and drought conditions could increase the dominance of lichens in biocrust communities to partly maintain the multifunctionality of biocrusts in this desert ecosystem.

Biological soil crusts (biocrusts) are essential for ecosystem functioning, especially in drylands. However, we lack the knowledge of how ecosystem multifunctionality (EMF) responds to the development of biocrusts and the key factors mediating EMF during biocrust succession. In this study, we tested a series of essential ecosystem functions of the biocrust system and calculated a weighted EMF index, a processes-based EMFprocesses index, and a resource storage and availability based EMFpools index. Sequencing of the 16S rRNA gene and ITS gene was used to test differences in the community compositions of 16S rRNA gene-based organisms and ITS gene-based fungi in different biocrust stages. Results showed that the changing patterns and driving factors of all the three multifunctionality indices were similar. Later developed biocrust stages exhibited higher values of all three EMF indices. The 16S rRNA gene-based diversity reduced with biocrust succession. Biodiversity-EMF relationships varied when considering different biocrust stages and organisms. Across all biocrust stages, significantly negative relationships existed between the EMF indices and 16S rRNA based α-diversity, whereas positive relationships occurred between the EMF indices and both 16S rRNA and ITS gene-based β-diversity. Further analyses indicated that the increasing relative abundance of non-cyanobacterial photosynthetic organisms (represented by chloroplast sequences and lichenized fungi) was the key predictor of all three EMF indices during biocrust succession. Specifically, these organisms were Streptophyta, Chlorophyta and Bacillariophyta and lichenized fungi, e.g., Verrucaria, Caloplaca and Aspicilia. This study provided a mechanistic understanding of how biological compositions and diversity drive EMF with biocrust development.

The ability of lichen transplant Evernia prunastri (L.) Ach. to reflect air concentration and spatial distribution of 7 polychlorinated dibenzodioxins (PCDDs), 10 polychlorinated dibenzofurans (PCDFs), and 23 polychlorinated biphenyls (PCBs) was evaluated through the construction of a wide and dense biomonitoring network. For this purpose, 23 lichen transplants were placed in a highly polluted area in Central Italy, characterized by the presence of different local emission sources such as a power plant, a steel plant, vehicular traffic, and domestic heating. The high spatial resolution data obtained from lichens were used to map the spatial distribution of the studied compounds, useful to identify the location and strength of target compounds sources over the territory. The maps showed that the highest concentrations of the pollutants were detected, as expected, in the sites close to the power plant and to the steel plant, confirming their important role as persistent pollutants emission sources. The statistical analysis performed on the spatially resolved data allowed us to identify the steel plant as the main source of PCDD/Fs, while PCBs were emitted by both the steel plant and the power plant. Finally, the efficiency of lichen transplants to reflect PCDD/Fs and PCBs atmospheric concentrations was assessed by comparing lichen data with POPs deposition measured by bulk deposition samplers at sites impacted by intensive emission sources; good results were achieved from the comparison (R2 > 0.79). Lichen transplants have demonstrated to be suitable biomonitors of POPs, allowing to obtain a high spatial monitoring network. The low-cost biomonitoring and experimental approach described in this study can be applied to other monitoring campaigns for identifying localizing emission sources of POPs in areas contaminated by several disaggregated sources.

Alzheimer's disease (AD) is the most prevalent form of dementia with a complex pathophysiology not fully elucidated but with limited pharmacological treatment. The Usnic acid (UA) is a lichen secondary metabolite found in two enantiomeric forms: (R)-(+)-UA or (S)-(-)-UA, with antioxidant and anti-inflammatory potential. Thus, given the role of neuroinflammation and oxidative injury in the AD, this study aimed to investigate experimentally the cognitive enhancing and anti-neuroinflammatory effects of UA enantiomers. First, the interactions of UA on acetylcholinesterase (AChE) was assessed by molecular docking and its inhibitory capability on AChE was assessed in vitro. In vivo trials investigated the effects of UA enantiomers in mice exposed to Aβ1−42 peptide (400 pmol/mice) intracerebroventricularly (i.c.v.). For this, mice were treated orally during 24 days with (R)-(+)-UA or (S)-(-)-UA at 25, 50, or 100 mg/kg, vehicle, or donepezil (2 mg/kg). Animals were submitted to the novel object recognized, Morris water maze, and inhibitory-avoidance task to assess the cognitive deficits. Additionally, UA antioxidant capacity and neuroinflammatory biomarkers were measured at the cortex and hippocampus from mice. Our results indicated that UA enantiomers evoked complex-receptor interaction with AChE like galantamine in silico. Also, UA enantiomers improved the learning and memory of the animals and in parallel decreased the myeloperoxidase activity and the lipid hydroperoxides (LOOH) on the cortex and hippocampus and reduced the IL-1β levels on the hippocampus. In summary, UA restored the cognitive deficits, as well as the signs of LOOH and neuroinflammation induced by Aβ1−42 administration in mice.

Highlights: • We used a space-for-time approach to study fire legacy over more than four decades. • Soil temperature and active layer depth recovered after >44 years. • Vegetation did not completely recover to a pre-fire state. • Burnt areas had lower lichen and higher bryophyte and shrub cover. • Betula nana showed increased vitality, indicating a strong fire legacy effect. Wildfires are relatively rare in subarctic tundra ecosystems, but they can strongly change ecosystem properties. Short-term fire effects on subarctic tundra vegetation are well documented, but long-term vegetation recovery has been studied less. The frequency of tundra fires will increase with climate warming. Understanding the long-term effects of fire is necessary to predict future ecosystem changes. We used a space-for-time approach to assess vegetation recovery after fire over more than four decades. We studied soil and vegetation patterns on three large fire scars (>44, 28 and 12 years old) in dry, lichen-dominated forest tundra in Western Siberia. On 60 plots, we determined soil temperature and permafrost thaw depth, sampled vegetation and measured plant functional traits. We assessed trends in Normalized Difference Vegetation Index (NDVI) to support the field-based results on vegetation recovery. Soil temperature, permafrost thaw depth and total vegetation cover had recovered to pre-fire levels after >44 years, as well as total vegetation cover. In contrast, after >44 years, functional groups had not recovered to the pre-fire state. Burnt areas had lower lichen and higher bryophyte and shrub cover. The dominating shrub species, Betula nana, exhibited a higher vitality (higher specific leaf area and plant height) on burnt compared with control plots, suggesting a fire legacy effect in shrub growth. Our results confirm patterns of shrub encroachment after fire that were detected before in other parts of the Arctic and Subarctic. In the so far poorly studied Western Siberian forest tundra we demonstrate for the first time, long-term fire-legacies on the functional composition of relatively dry shrub- and lichen-dominated vegetation.

Invasive alien species are considered as one of the major threats to global biodiversity. Many widely used forestry trees are potentially invasive, spreading from planting sites into adjoining areas modifying community composition, and altering the native forest. In the Canary Islands, Castanea sativa was established half a millennium ago, in the distributional area of the laurel forest, an endemic forest of the Macaronesia. The impact of invasive species on ecosystem services and more specifically their impact on epiphytic lichens is totally unknown in these archipelagos. The main aim of this work has been to find out if the chestnut tree can host an analogous species composition, richness, and diversity of epiphytic lichens such as those present in the native forest from the Canary Islands. Whilst species richness in both habitats is high, the composition is significantly different. The characteristic species were also different. The chestnut tree hosted rare species linked to ancient and well-preserved forest environments. For this reason, we propose not to completely eradicate the chestnut tree in the Archipelago, but we consider the management and control of its expansion to be essential. Preserving ancient specimens can serve as a lichen biodiversity reservoir. Keywords: Canary Islands; Chestnut tree; Exotic invasion; Lichen; Monteverde.

(2021): How sensitive are epiphytic and epixylic cryptogams as indicators of forest naturalness? Testing bryophyte and lichen predictive power in stands under different management regimes in the Białowieża forest. - Ecological Indicators, 125: 107532 [19 p.]. https://doi.org/10.1016/j.ecolind.2021.107532.|
The aim of this study was to test the sensitivity of epiphytic and epixylic bryophytes and lichens as indicators of forest naturalness, by comparing their diversity patterns with forest structural, compositional and historical features associated with different management/protection regimes and protection time spans. The study was carried out in the Białowieża Forest (Poland). Out of 1370 pre-existing inventory plots established all across the Polish part of the Białowieża Forest, we randomly selected 10 plots for each of the 18 plot aggregation groups resulting from the combination of 3 management/protection regimes and 6 habitat types, for an overall number of 180 plots. At each of them, we carried out bryophyte and lichen sampling on four substrates (coarse woody debris – CWD, standing dead trees, stumps, living trees). The management/protection regimes exemplifying the gradient of forest naturalness were: the 100 years-old Białowieża National Park (BNP), a set of more recently established nature reserves and managed forests. We tested differences in mean species richness values among management/protection regimes, protection time spans, habitat types and stand age classes by analysis of variance and calculated coefficients of correlation with 45 selected structural and compositional features of forest stands. Differences in species composition of epiphytic and epixilic bryophytes and lichens among management/protection regimes were tested by ordination methods. Lastly, we compared frequency of red-listed species and primeval forest relics among management/protection regimes. Species richness of lichens was significantly correlated with the degree of forest naturalness assessed by structural and historical features along the naturalness gradient, with the highest number of species recorded in BNP and the lower in managed stands, while bryophyte number did not exhibit a clear dependence on the management regimes. Relic species of primeval forests and red-listed species occurred with significantly higher frequency in protected areas than in managed forests for both lichens and bryophytes, with the highest frequency observed in BNP for lichens and in nature reserves for bryophytes. Volume of deadwood, particularly of CWD in advanced decays stage, species richness of undergrowth vascular plants, tree layer diversity, shrub cover and herb layer cover exhibited the strongest correlation with cryptogam species richness and cover on the various substrates. Response to light availability strongly differenciated bryophyte and lichens optimal niches. The results of this study clearly show that cryptogams, and lichens in particular, are indeed reliable ecological indicators of forest status, since they sensibly intercepted the environmental changes observable along the tested naturalness gradient. Keywords: Ecological indicators; Forest naturalness gradient; Forest management regimes; Primeval forest relics; Red-listed species; Species richness.

Air pollution has become a subject of extensive study of several disciplines and it is identified as one of the most damaging factors for the ecosystem and human health. In urban areas, particle emission can be found in suspension and therefore a portion of them is inhalable for humans, or deposited on streets and several surfaces, including lichen’s thallus. We studied particulate matter (PM) (by traffic emission) accumulated in native lichens Parmotrema pilosum in order to carry out a magnetic biomonitoring over 2016 and 2017. For this purpose, the environmental magnetism method was complemented with inductively coupled plasma optical emission spectrometry, scanning electron microscopy, and geostatistical methods. The accumulated iron oxides on lichen’s thallus include potential toxic elements, such as Ba, Cr, Ni, and V. Fe-rich particles related to vehicle emissions correspond to (ultra)fine magnetite of inhalable sizes (PM2.5). Our results indicate a relation between concentration of magnetic particles and areas with high traffic, as well as the influence of rainfall on magnetic PM records. Magnetic biomonitoring is validated as a low-cost and complementary methodology to determine levels of air magnetic PM pollution in cities. Keywords Biomonitor .Geostatistics.Magneticproxy .

Lichens consisting of a symbiotic association of green algae or cyanobacteria and fungi are found in a variety of environmental conditions worldwide. Terricolous lichens, located in soils, affect the living and lifeless environment of the soil due to their effective secondary metabolite and enzymatic content. Terricolous lichens can increase the biological, chemical, and physical usefulness of soil. However, their effects in ensuring the bioavailability of contaminated soil are not known, especially on soil pollution caused by DDTs (p,p′-DDE, p,p′-DDD, p,p′-DDT). This research focuses on the effect of terricolous lichens on zucchini (Cucurbita pepo spp. pepo) grown in soil contaminated by DDTs, utilizing their secondary metabolite and enzymatic contents. Firstly, Peltigera canina, a terricolous lichen species, was added to soil contaminated by DDTs as powdered and intact thallus. After lichen addition to soil, zucchini was planted in. The oxidative stress and antioxidative enzyme activities of zucchini were measured. According to the results, P. canina treatments have a positive effect on the growth and development of zucchini, although oxidative stress was observed. Also, it was determined that powdered application had more effective results than intact thallus application. Keywords: Lichens . Peltigera canina . DDTs . Soil bioavailability . Oxidative stress .

In association with lichens, bacteria can play key roles in solubilizing sources of inorganic phosphates that are available in the environment. In this study, the potential of bacteria isolated from 15 Antarctic lichen samples for phosphate solubilization was investigated. From 124 bacteria tested, 66 (53%) were positive for phosphate solubilization in solid NBRIP medium, with a higher prevalence of Pseudomonas, followed by Caballeronia and Chryseobacterium. Most of the phosphate-solubilizing bacteria were isolated from Usnea auratiacoatra, followed by Caloplaca regalis and Xanthoria candelaria. Two isolates showed outstanding performance, Pseudomonas sp. 11.LB15 and Pseudomonas sp. 1.LB34, since they presented solubilization in the temperature range from 15.0 to 30.0 °C, and maximum quantifcation of soluble phosphate at 25.0 °C was 511.21 and 532.07 mg/L for Pseudomonas sp. 11.LB15 and Pseudomonas sp. 1.LB34, respectively. At 30.0 °C soluble phosphate yield was 639.43 and 518.95 mg/L with pH of 3.74 and 3.87 for Pseudomonas sp. 11.LB15 and Pseudomonas sp. 1.LB34, respectively. Fumaric and tartaric acids were released during the solubilization process. Finally, bacteria isolated from Antarctic lichens were shown to have the potential for phosphate solubilization, opening perspectives for future application in the agricultural sector and contributing to reduce the use of chemical fertilizers.

In bioaccumulation studies, sample devitalization through acid washing or oven drying is commonly applied to enhance the element accumulation efficiency of moss sample. Such aspect, however, has never been considered in biomonitoring surveys using lichens. In this study, the trace element accumulation performance of living (L) and dead (D) samples of the lichen Pseudevernia furfuracea was compared by a side-by-side transplanting at 40 sites in a large, mixed land use area of NE Italy for 8 weeks. Devitalization was achieved without any physico-chemical treatments, by storing lichen samples in a dark cool room for 18 months. Health status of lichens was assessed before and after the sample exposure by chlorophyll fluorescence emission. Although elemental analysis of the two exposed sample sets revealed a similar trace element pollution scenario, the content of 13 out of the 24 selected elements was higher in D samples. By expressing results as exposed-to-unexposed (EU) ratio, D samples show a higher bioaccumulation signal in 80% of transplant sites for Al, Ca, Fe, Hg, Pb and Ti. Overall, the health status of lichen samples might lead to interpretational discrepancies when EU ratio is classified according to the recently proposed bioaccumulation scale.

The diversity of lichen-associated bacteria from lichen taxa Cetraria, Cladonia, Megaspora, Pseudephebe, Psoroma, and Sphaerophorus was investigated by sequencing of 16S rRNA gene amplicons. Physiological characteristics of the cultured bacterial isolates were investigated to understand possible roles in the lichen ecosystem. Proteobacteria (with a relative abundance of 69.7–96.7%) were mostly represented by the order Rhodospirillales. The 117 retrieved isolates were grouped into 35 phylotypes of the phyla Actinobacteria (27), Bacteroidetes (6), Deinococcus-Thermus (1), and Proteobacteria (Alphaproteobacteria (53), Betaproteobacteria (18), and Gammaproteobacteria (12)). Hydrolysis of macromolecules such as skim milk, polymer, and (hypo)xanthine, solubilization of inorganic phosphate, production of phytohormone indole-3-acetic acid, and fixation of atmospheric nitrogen were observed in different taxa. The potential phototrophy of the strains of the genus Polymorphobacter which were cultivated from a lichen for the first time was revealed by the presence of genes involved in photosynthesis. Altogether, the physiological characteristics of diverse bacterial taxa from Antarctic lichens are considered to imply significant roles of lichen-associated bacteria to allow lichens to be tolerant or competitive in the harsh Antarctic environment.

chapter in book; Lichens are unequivocally responding to global change. Direct effects are so far apparent during the past three decades (since c. 1990) and in the temperate regions only. Interestingly, contrasting responses of lichens and other cryptogams to recent changes have been reported. Lichens have indirectly suffered from global change effects in arctic regions. In this chapter, predicted, observed, and uncertain effects related to lichen and climate change are discussed together with the habitats of vulnerable lichens, with special attention to mountain tops in the tropics—the most likely place for possible extinction of lichens as a result of global warming. The most severe effects of climate change, leading to probable extinctions, is expected (but has not been observed as yet) on high mountains in tropical regions.

Lichens comprise a number of unique secondary metabolites with remarkable biological activities and have become an interesting research topic for cancer therapy. However, only a few of these metabolites have been assessed for their effectiveness against various in vitro models. Therefore, the aim of the present study was to assess the effect of extract Pseudevernia furfuracea (L.) Zopf (PSE) and its metabolite physodic acid (Phy) on tumour microenvironment (TME) modulation, focusing on epithelial–mesenchymal transition (EMT), cancer-associated fibroblasts (CAFs) transformation and angiogenesis. Here, we demonstrate, by using flow cytometry,Western blot and immunofluorescence microscopy, that tested compounds inhibited the EMT process in MCF-10A breast cells through decreasing the level of different mesenchymal markers in a time- and dose-dependent manner. By the same mechanisms, PSE and Phy suppressed the function of Transforming growth factor beta (TGF-)-stimulated fibroblasts. Moreover, PSE and Phy resulted in a decreasing level of the TGF- canonical pathway Smad2/3, which is essential for tumour growth. Furthermore, PSE and Phy inhibited angiogenesis ex ovo in a quail embryo chorioallantoic model, which indicates their potential anti-angiogenic activity. These results also provided the first evidence of the modulation of TME by these substances. Keywords: tumour microenvironment; EMT; MCF-10A; fibroblasts; HUVECs; angiogenesis; lichens; secondary metabolites.

The lichenized fungus Verrucaria hunsrueckensis (Verrucariaceae, Ascomycota) is described and distinguished from similar lichens by ascospores with an exceptionally large length to width ratio, brown and small exciple, distinct involucrellum, goniocyst- like thallus structure, growth on acidic siliceous rocks and characteristic motives in sequences of the nuclear ribosomal internal transcribed spacer region. The new species is known from only one site in the Hunsrück-Hochwald National Park (Rhineland Palatinate, Germany), where it grows on quartzitic rocks in half shaded situations at the margin of rock screes in an old growth forest. Its discovery supports the view that within the Verrucariaceae some well recognizable species may be naturally rare and their sites worthy of protection.

chapter in book; summary and conclusions: The question of what constitutes an individual is the most pressing issue in the evolutionary biology of lichens. Specifically, we need to understand better the genetic and evolutionary relationships between phycobionts and mycobionts of lichen species. In addition, we need more information about genetic diversity within the mycobiont and phycobiont components of individual thalli. What are the phylogenetic relationships between phycobionts of different lichens? Do one, few, or many mycobiont genotypes contribute to the structure of lichen thalli? Is there as much genetic heterogeneity within the fungal symbionts of individual thalli as appears on the basis of the limited data now available? Lichen thalli might be better viewed as populations than as organisms. Does selection operate within lichen thalli? Is selection among thalli more comparable to classical group selection than to individual selection? In apparent contradiction to the remarkable levels of variation that appear to characterize populations oflichen thalli, there is little evidence of ecotypic differentiation between populations with regard to important environmental characteristics. Instead, physiological acclimatization appears to be of great importance for survival of lichens in varying environments. This impression may well be attributable to a paucity of researchers and incomplete information. On the other hand, thorough studies of several species where genetic differentiation was expected have failed to yield such evidence. In spite of predictions that populations of haploid bryophytes might contain low levels of genetic variability, they, too, have been shown in general to contain moderate or even high levels of electrophoretically detectable protein variation. Variation in quantitative traits also appears to be common within species and sometimes within populations. This level of variation suggests either that sexual reproduction occurs more frequently in bryophytes than has been thought, or that frequent sex is not necessary for the generation and maintenance of variability. The presence of ample variation makes it all the more remarkable that genetically specialized ecotypes appear not to be the most common response to environmental heterogeneity in this group of organisms. To the contrary, broad tolerances and the ability to acclimatize to environmental change characterize those species of bryophytes that have been studied in detail. In this important regard, bryophytes and lichens appear to bear significant similarity.

chapter in book; summary: If the pH is high, bryophytes can successfully compete only in areas of high aeration (e.g. Fissidens grandifrons) or low nutrients or in shaded areas where light is insufficient for higher plants (Bain and Proctor 1980). Acidification can favour bryophytes by providing more C02 and reducing absorption of metals. Ability to sequester heavy metals and radionuclides in the cell wall, as electron-dense particles, and in vacuoles permits survival of bryophytes under conditions in which many vascular plants cannot survive. Increased temperatures, on the other hand, are likely to decimate both bryophytes and lichens in areas where cool temperatures once favoured their growth. Turbidity may favour bryophytes in shallow water by reducing the light intensity, but associated abrasives can damage buds and decrease reproduction.

chapter in book; concluding remarks: Bark and soil acidification is caused by the total H+ ion input to the system. For epiphytes, extreme events are evened out by the buffering capacity of bark, so that the best predictions of epiphyte response are probably made on annual averages of pollutant loading. For terricolous cryptogams a similar situation may hold, depending on the intimacy of contact with the substrate. This is in contrast to SO2 effects, where episodic pollutant peaks may be of overriding importance. As each tree (individual or species) has finite buffering capacity, it may be possible to estimate the additional loading of H+ ions that will lead to acidification, the so-called critical load for the system. Many terricolous species occur on soils whose critical load for H+ is exceeded and acidification is occurring. Although some species seem to be resistant to field experimental application of acid rain, the decline of others has been described and urgent action to reduce emissions is necessary for their conservation. The problem of defining critical loads for N has not been resolved. This is determined by the biological response of the system (whereas for H+ it is the measurable chemical property of buffering capacity), which is very difficult to quantify. Nevertheless, N inputs are causing changes to cryptogam populations and work is, therefore, necessary to discover the mechanism of change. Future studies of acid rain may need to encompass the effects of predicted climatic change and CO2 rise. For instance, global climate change may lead to an increase in rainfall for parts of north-west Europe. This may lead to an increase in the total deposition of pollutants onto cryptogam communities, although pollutant concentrations may fall. It is important, therefore, that emission reduction policies take account of possible further climatic scenarios and their relationship with air pollution.

The use of a high-density lichen transplant network together with quantitative wind relationships (WQRs) made it possible to evaluate the influence of an airport and surrounding road network on the spatial variation of polycyclic aromatic hydrocarbons (PAHs) and trace elements at both the local and whole study area scale. WQRs clearly showed that the parking/idling/taxiing area (PIT), but not the landing/take-off zones (LTZs), as well as the north/north-east part of the road network were contributors at the whole study area scale to the spatial variation of elements like Ni, Mo and V, i.e. those associated with ultrafine particles due to their involvement in anti-wear materials, and of total PAHs. In the case of an airport, such a result can have strong management implications. Traffic also affected the concentration of the prevailing volatile organic compounds. In contrast, LTZs and high traffic density values were correlated with peaks of Zn, Mo, Cu, Co, Mn, Ni, V, Al and Sb when associated with coarse particulate matter generated by deterioration of the landing gear, fuselage, wings, runway asphalt and brakes. The remarkable percentage of high-speed winds strongly affected both the spatial distribution of anthropogenic emissions and their atmospheric dilution, resulting in a rather low level of contamination. Our results suggest that biomonitoring can be much improved when matched with WQRs and that, in the event of high wind speeds, PAHs associated with the gas phase and fine/ultrafine particles are effective contamination tracers mainly at the whole study area scale whereas trace elements reveal contamination patterns at both scales.

Mulching (cutting of vegetation without removal of clippings) is used as a low-cost method for maintaining remote or abandoned grasslands in Slovakia. The likely consequence of mulching is seasonal nutrient enrichment resulting from decomposition of plant litter by saprotrophic organisms. The potential changes in biodiversity of the ecosystem caused by long-term application of mulching are to date only very poorly understood. In order to examine the impact of mulching on soil mycobiota, we compared six different grassland management regimes applied over nine years on a sub-montane oligotrophic Nardus pasture in the Central Slovakia. The diversity of soil fungi was assessed using DNA metabarcoding of the ITS2 regions of the nrRNA locus performed by Illumina MiSeq. We focused on a particular group of macrofungi which is characteristic of traditionally managed and undisturbed European grasslands, and which are often the dominant soil fungi in these habitats. These are collectively known as CHEGD fungi (the acronym of the constituent taxa: Clavariaceae, Hygrophoraceae, Entolomataceae, Geoglossaceae and Dermoloma). We compared the relative abundance and diversity of CHEGD fungi with the total fungal and plant diversity. CHEGD fungi were dominant across all management treatments. Although there were no statistical effects of treatments on total fungal richness and diversity, CHEGD fungi and vascular plants diversity and richness were lower on plots where mulching or no management were imposed, suggesting that such management regimes would have a negative impact on grassland fungi. However, no single treatment covered the total CHEGD diversity of the study, indicating that the localized use of mulching in addition to traditional managements can enhance overall diversity of grasslands in the area. Our results also suggest that the impact of mulching depends on the season when the grassland is mulched and it might be reduced by combination with other management treatments. The high relative abundance and sensitivity of CHEDG fungi in oligotrophic grasslands to management treatments makes them excellent indicators of grassland natural quality and is consistent with the ecological importance of this fungal group.

Lichens are traditionally defined as a symbiotic relationship between fungi and algae and/or cyanobacteria. This union forms a unique structure called the thallus, which attaches to surfaces such as rocks and tree bark. Recent reports challenge the view that lichens are comprised of one fungus and one photobiont, and instead suggest that they are a consortium of microbes. Much of lichen biology remains unknown as most of our knowledge of lichens is limited to morphological characteristics with little to no functional analysis of lichen genes. However, lichens and biofilms share many similar physiological traits which when compared may assist in our understanding of lichens. Similarities between the two are rooted in their lifestyle, where these microbes and their extracellular products attach themselves to a surface and grow in a community structure. Biofilms and lichens alike have distinct features that allow for their lifestyle and identification, such as specific developmental patterns, formation of an extracellular matrix, and their ability to resist abiotic stressors. We argue here that one can gain insight into the cellular processes and evolutionary origins of lichens, which are currently undetermined, by applying knowledge gleaned from studies on microbial biofilms, with a particular focus on fungal biofilms.

Riparian forests are among the most threatened ecosystems and their conservation are essential for the preservation of biological communities. The main objective of this study was to analyze the environmental quality of riparian forest sites inserted in three environmental matrices (rural, urban, industrial) by using structural parameters and functional traits of the lichen community. Lichens were sampled in the seven forest areas, along the Hydrographic Basin of Sinos River (HBSR), using the acetate method. Structural parameters and functional traits were analyzed in all sites as well as secondary metabolites of lichen species and photosynthetically active radiation (PAR) and latitude. 164 species were recorded. The richness per phorophyte, coverage and diversity were higher in the sites of the rural matrix in relation to the urban/industrial matrix, as well as the richness and functional diversity. Species with Trentepohlia photobiont, crustose growth form and apothecia reproductive strategy obtained the greatest richness in the rural sites. The greatest richness of species with secondary metabolites was registered in the forest sites of the urban/industrial matrix. Functional characteristics such as luminosity and altitude significantly impacted the distribution of species in riparian forest sites. The structural parameters and functional traits alterations in the lichen community demonstrated the depreciation of the environmental quality of the forest sites of the spring towards the mouth of the main river that constitutes the Hydrographic Basin in the subtropical region.

Biological soil crusts (BSC) are widespread in the Monte desert. BSC, by fixing atmospheric N and retaining soil moisture, may enhance grass emergence, growth, and nutritional value. Our aim was to evaluate the effect of different functional types of BSC from the Monte desert on soil moisture and nutrients, N fixation, respiration, grass emergence, growth, and C/N. We sowed Leptochloa crinita seeds in pots with different BSC types (dominated by cyanobacteria, squamulose phycolichens, squamulose cyanolichens, gelatinous cyanolichens, and mosses) under two irrigation treatments: well watered and drought. We determined soil, BSC and grass properties related to nitrogen, phosphorus, and water cycles. In soils under BSC, we determined moisture, nitrate, and phosphate at two depths. In BSC, we determined total N, organic matter, ammonium, respiration, and δ15N. Finally, in grasses growing under BSC, we determined seedling emergence, grass biomass, C/N, and δ15N. All BSC types except cyanobacteria increased soil total N, ammonium, and respiration rates compared to bare soils under drought conditions. Cyanobacteria BSC increased soil moisture under drought conditions, while squamulose phycolichens and mosses increased it under well watered conditions. All BSC types increased underlying soil nitrate under well watered conditions, and decreased phosphate in at least one experimental condition. All BSC types improved at least one grass variable: cyanobacteria decreased C/N; squamulose cyanolichens increased emergence and decreased C/N; squamulose phycolichens increased emergence and biomass; gelatinous cyanolichens decreased C/N; and mosses increased emergence, biomass, and decreased C/N. The differential effects of each BSC type on soil and grass variables, under drought and well watered conditions, suggest the importance of BSC functional diversity on ecosystem functions of water regulation and nutrient cycling.

The present study summarizes three decades of studies on 137Cs transfer to various species of lichens, graminoids, herbs and woody plants across a ~3000 km2 area used as mountain pasture for reindeer and other ruminants. The investigation comprised of field studies covering the period 2011–2016, and a compilation of studies and data for the preceding period (1986–2010). Altogether, more than 700 individual vegetation samples were considered. For lichens, relatively fast decrease in contamination levels was observed during the first decade after the Chernobyl fallout (ecological half-time of about 3 years). For later years there seems to be a continuous re-contamination which results in a “steady state” where time-trends are mainly governed by physical decay of 137Cs. For green plants, decline in transfer factors (TF) (i.e. the ratio between activity concentration in vegetation and activity density in soil) during the period 1986–2012 was not as pronounced as for lichens: Some species showed significant decrease with time, while others did not. 25–30 years after the Chernobyl accident, 137Cs levels in lichens and green plants were significantly dependent on the levels in soil (R2 between 0.53 and 0.57), but there were also some significant differences in transfer between sampling sites. Moreover, marked variability in TFs was found between different plant species growing at the same site, whereas such differences were not found for reindeer lichens.

Alpine ecosystems are under increasing pressure due to tourism and recreational activities. When leaving desig- nated trails as is frequently observed, visitors can cause unintentional damage to vegetation. This study investi- gated the effect of human trampling on the dominant species of vascular plants, bryophytes and lichens along an infrequently used hiking trail in an alpine ecosystem in sub-arctic Sweden. The hypothesis tested was that prox- imity to the trail (as an effect of more people leaving the trail for a short distance compared to a longer distance) causes a decrease in species with low resistance to trampling. With a greater decrease in taller forbs and shrubs than in graminoids and prostrate plants, a greater decrease in lichen than in bryophyte species, and a change in vegetation composition. The results showed that proximity to the trail did not cause a decrease in the majority of dominant species, with none of the eight most dominant vascular plants showing any significant effects of prox- imity to the trail. One bryophyte species ( Dicranum elongatum ) among the six most commonly found decreased with proximity to the trail. Three lichen species ( Cladonia arbuscula, Cladonia uncinalis, Ochrolechia frigida ) among the eight most common species decreased with proximity to the trail. There was no evidence that taller species decreased with proximity to the trail, although the deciduous shrub Betula nana showed a tendency for a decrease. Proximity to the trail caused a greater decrease in lichen species than in bryophyte species. Multivariate analyses showed that distance from trail and transect direction had significant effects on overall vegetation composition. The level of low-intensity trampling recorded indicates that current numbers of hikers at the site can be sustained for longer periods with minimum impact on vascular plant species, but to get a more general understanding of the impact of low-intensity trampling data from additional sites are needed.

In this study, we examine glacier retreat and associated processes in the Lejiamayu valley, central Cordillera Blanca, Peru (9.27◦S; 77.48◦W) since the Last Glacial Maximum (LGM). Based on detailed mapping of well- preserved moraines, we reconstruct glacier extent during the LGM, the Antarctic Cold Reversal (ACR) and the Little Ice Age (LIA), being 21.34 km2 (LGM), 13.68 km2 (ACR) and 6.84 km2 (LIA). We document that glacier extent decreased to 2,86 km2 since the end of the LIA in this catchment (ice loss 58%). In addition, we explore the colonization and growth of lichens and Schmidt-hammer rock test R-values over the deglaciated surfaces, sug-gesting a relationship to possible evironmental controls rather than to the timing of the exposure. Further, we use empirical glacier velocity-based equation to estimate maximum potential future volume of the new glacial lake forming in the upper part of the valley (4725 m a.s.l.; 2.2 Mm3). We conclude that previous estimates of future lake volume might have been underestimated and that the sufficiency of the glacial lake outburst flood (GLOF) mitigation measures implemented at downstream located Lake Lejiacocha (4628 m a.s.l.) should be revised in future.

Many lichen secondary metabolites contributed to the feld of pharmacology as an active ingredient of diferent drugs for years. In the present study, we aimed to test the anticancer activity of olivetoric acid (OA), which we isolated from Pseudevernia furfuracea (L.) Zopf in human hepatocellular carcinoma cells (HepG2). In addition, we used non-tumoral human liver cells (THLE2) to test the level of side efects of OA in vitro. For this purpose, cytotoxic (apoptotic and necrotic), oxidant, genotoxic activities and expression levels of apoptotic genes caused by diferent concentrations (12.5–400 mg/L) of OA were tested on both cells. Flow cytometric and cytotoxicity tests (MTT and LDH) revealed that OA (100–400 mg/L) had a higher rate of apoptotic efects on HepG2 cells compared to THLE2. Total oxidative stress and oxidative DNA damage levels caused by all concentrations of OA on HepG2 cells was signifcantly (p<0.05) higher compared to negative control. Trials with concentrations of 100–400 mg/L signifcantly (p<0.05) increased total antioxidant capacity on THLE2 cells compared to the control group. As a result, based on human hepatocellular carcinoma, it is hoped that OA may contribute to the combined or alternative treatment process.

Many lowland rainforests in Southeast Asia are severely altered by selective logging and there is a need for rapid assessment methods to identify characteristic communities of old growth forests and to monitor restoration success in regenerating forests. We have studied the effect of logging on the diversity and composition of lichen communities on trunks of trees in lowland rainforests of northeast Borneo dominated by Dipterocarpaceae. Using data from field observations and vouchers collected from plots in disturbed and undisturbed forests, we compared a taxonomy-based and a taxon-free method. Vouchers were identified to genus or genus group and assigned to functional groups based on sets of functional traits. Both datasets allowed the detection of significant differences in lichen communities between disturbed and undisturbed forest plots. Bark type diversity and the proportion of large trees, particularly those belonging to the family Dipterocarpaceae, were the main drivers of lichen community structure. Our results confirm the usefulness of a functional groups approach for the rapid assessment of tropical lowland rainforests in Southeast Asia. A high proportion of Dipterocarpaceae trees is revealed as an essential element for the restoration of near natural lichen communities in lowland rainforests of Southeast Asia.

Physconia hokkaidensis methanol extract (PHE) was studied to identify anticancer effects and reveal its mechanism of action by an analysis of cytotoxicity, cell cycles, and apoptosis biomarkers. PHE showed strong cytotoxicity in various cancer cells, including HL-60, HeLa, A549, Hep G2, AGS, MDA-MB-231, and MCF-7. Of these cell lines, the growth of MDA-MB-231 was concentration-dependently suppressed by PHE, but MCF-7 was not affected. MDA-MB-231 cells, triple-negative breast cancer (TNBC) cells, do not express estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2), whereas MCF-7 cells are ER-positive, PR-positive, and HER-2-negative breast cancer cells. The number of cells in sub-G1 phase was increased after 24 h of treatment, and annexin V/PI staining showed that the population size of apoptotic cells was increased by prolonged exposure to PHE. Moreover, PHE treatment downregulated the transcriptional levels of Bcl-2, AMPK, and p-Akt, whereas it significantly upregulated the levels of cleaved caspase-3, cleaved caspase-9, and cleaved-PARP. In conclusion, it was confirmed that the PHE exhibited selective cytotoxicity toward MDA-MB-231, not toward MCF-7, and its cytotoxic activity is based on induction of apoptosis.

This genus have never been studied in detail in our territory. M&M: The morphology, anatomy and chemistry of the species were studied through the review of fresh specimens collected in the field and the study of different herbarium collections, following standardized protocols. Results: Fifteen species of Pannaria are registered for Argentina, 3 of them for the first time: P. conoplea, P. malmei, and P. tavaresii. A new synonym is proposed (P. euphylla = P. calophylla). Descriptions, photographs, and actualized information on their distribution and ecology, and a key for their identification are presented. Conclusions: Most of the mentioned species were found in the Andean-Patagonian forests, with the exception of P. conoplea, P. malmei and P. tavaresii, which were found in central Argentina, in high altitude forests of Polylepis.

[in Spanish with English abstract: ] In this study we tested whether young (Holocene) lava flows can be confidently dated based on the preservation of the primary geomorphological features, the stratigraphic position and historical records. To verify this hypothesis, we combined in situ-produced cosmogenic 36Cl exposure dating and lichenometry on two lava flows from the last eruptive cycle of Citlaltépetl (Pico de Orizaba), called Lava flow “A” and “B”, previously attributed to 16th and 17th century eruptions, respectively. On lava flow “A”, the measured in situ-produced 36Cl concentrations lead to a mean age of 3.03 ± 0.70 ka, while lichenometry yields a minimum age of ~1,130 years. Regarding lava flow “B”, the measured in situ-produced 36Cl concentrations lead to a mean age of 1.45 ± 0.35 ka, whereas lichenometry gives a minimum age of ~1,000 years. The exposure ages derived from these methods indicate that both lava flows are significantly older than previously thought and therefore the combination of the preservation of the primary geomorphological features, the stratigraphic position and the historical records is not enough to determine their ages. Overall, the combination of in situ-produced 36Cl cosmic ray exposure dating and lichenometry, used for the first time in Mexico and supported by geomorphological, stratigraphic and historical record criteria, has a considerable potential for dating purposes and it could be useful to refine the eruptive history of other Mexican volcanoes.

The seasonally dry subtropical forest, especially the Espinal forest in central Argentina (one of the most fragmented ecoregions), is affected by intensive agricultural activity. These activities are the main anthropogenic sources of atmospheric nitrogen compounds and their effects on lichens have been extensively studied, making them excellent ecological indicators. However, in the Espinal forest, the agricultural emissions are not monitored therefore analysis of the response of lichen diversity to these activities has a fundamental role in providing baseline data for monitoring. We analyzed changes in the frequency of families and genera of epiphytic lichen communities in 39 circular buffer areas at different scales comprising crop production, stock farming (feedlots), grazing and forest. Significant correlations at different taxonomic levels were detected in relation to land use. Frequency of Physciaceae increased with an increasing area of cropland to a distance of 600 m. Likewise a positive correlation was observed between the frequency of Collemataceae and the forest area. At genus level, Physcia presented a different response to livestock according to the intensity of production, since the frequency of these species increased in forest patches surrounded by grazing but decreased in areas with livestock farming where the stocking density is higher. This result could indicate an eutrophication process in the Espinal ecosystem, even for Physcia species. Our results can be used to start a list of indicator species to impact of agricultural in forest ecosystems. Keywords: Agricultural emissions; Lichen communities; Livestock farming; Nitrophytic.

[in Spanish with English abstract: ] Lichens are recognized as bioindicators of ecosystem processes associated with environmental disturbances. However, its evaluation in the time requires systematic records of biodiversity which are non-existent in the Katalalixar National Reserve. The aim of this study was to catalog the richness and distribution of lichen biota of Katalalixar National Reserve, not only by identifying the species but interpreting them in their ecological and biogeographic context. By random sampling in Nothofagus nitida, Pilgerodendron uviferum forests and peat bogs 70 species were identified, belonging to 32 families and 65 genera. A high number of endemism was found, with 34% of the species endemic to Southern South American and the Chilean endemic Pseudocyphellaria guzmanii constitutes a new record for the Aisen Region. Keywords: endemism; Katalalixar; lichens.

[in Portuguese with English summary: ] Studies were carried out from March 1973 to September 1974 to ascertain the microclimate in the Amazon Campina ecosystem. This ecosystem was in biological equilibrium with its natural vegetation growing on sandy soil. The data gathered included temperature readings of soil taken from three ecologically different sites in the Campina, air temperature readings and relative humidity readings in the Campina and Campinarana. The following mean temperature variations were observed for the soil: exposed soil (sand) 16.7°C, partially exposed soil (sand under lichens) 8.8°C, unexposed soil (under vegetation) 6.1°C. The mean temperature variation of the air m the Campina was 20. 3°C, and in the Campinarana 14.QoC . The relative humidity varied between 81-90% in the Campina, and 91-97% in the Campinarana. These microclimatic variations are a partial result of the vegetation cover which limits the penetration of solar energy in these two related systems within the ecosystem.

chapter in book; Concluding remarks: The effects of agricultural chemicals on lichens and bryophytes deserve further study because these organisms may prove to be sensitive, selective, and convenient biomonitors of such environmental pollutants. Pesticide and fertilizer residues can be recovered from both lichens and bryophytes, which may, however, show rapid dynamic changes. Although changes in the floristic composition of treated habitats have been observed, more carefully planned studies are needed to separate the effects of direct from indirect damage. The loosely applied expression 'fertilizer effects' needs careful definition in terms of both floristic and chemical parameters, including the distinction between pH and specific chemical effects.

chapter in book; conclusions: "Over the last 20 years it has become clear that the epiphytic communities of the older British woodlands are of great conservation importance. This is true above all of the old pasture-woodlands of varied types, which are so scarce in a European perspective that the better British examples–above all the New Forest woodlands and the best of the few remaining deer parks–are now a unique conservation resource on an international scale. However these woodlands require careful management. Wherever possible, grazing of some kind–if deer are impracticable, then cattle, pomes, or in special cases, sheep–should be reintroduced. There are numerous plans already in this direction. Without pasturing, the unique character of these woodlands will be lost for ever. The creation of new pollards is very desirable, including not only oak, beech, ash, and hornbeam pollards, but also, in appropriate cases, holly pollards, a feature hardly known outside the British Isles. New plantings of trees, or aided natural regeneration, is necessary in many cases where the tree stocking is down to rather small numbers of ancient trees without younger successors. Fortunately, the severe storms of recent years have done remarkably little damage to the ancient oaks of most of the British pasture woodlands, but more younger trees are needed in some areas to bridge the 'generation gaps' before it is too late."

chapter in book; [p. 177:] "So far only the initial stages of reinvasion have been observed, and these predominantly on trees in the more polluted areas. Early indications are that a narrow range of mobile, competitive species with a high reproductive capacity and a wide ecological amplitude are the first invaders of the shrinking lichen deserts. Infiltration is not uniform, high pH and eutrophicated habitats being favoured. It seems that since the rise of air pollution in the middle of the last century a general eutrophication of much of lowland Europe has taken place. Now that the masking effect of SO2 is being removed it is becoming apparent that one form of pollution has been replaced by another, with the consequence that the original pre-industrial revolution lichen flora is likely to return only locally. Reinvasion of lichen deserts is not their expansion in reverse. A hard lesson for lichenologists to grasp is that due to differential time lag phenomena their organisms can only indicate pollution abatement, not monitor it."

Seven species of Siphula Nylander have been found in Venezuela (including Páramos and Guayana Highlands). Three species from the Guayana Highlands viz. S. chimantensis V. Marcano, S. subsimplex V. Marcano and S. subpteruloides V. Marcano are described as new to science. A key to the species is presented together with data on morphology, chemistry, variation, taxonomy, habitat and distribution. The data indicate that of the taxa reported from Venezuela, four are known only from the Guayana Highlands, one is known only from the neotropics, and two are pantropical. The high concentration of Siphula species seen in the Guayana Highlands suggests that this region constitutes an important centre for speciation and endemism for the genus.

Three species of the lichen Usnea (U. baileyi (Stirt.) Zahlbr., U. bismolliuscula Zahlbr. and U. pectinata Stirt.) and nine associated endolichenic fungi (ELF) were evaluated using a metabolomics approach. All investigated lichen crude extracts afforded antibacterial activity against Staphylococcus aureus (minimum inhibitory concentration (MIC): 0.0625 mg/mL), but none was observed against Escherichia coli, while the ELF extract Xylaria venustula was found to be the most active against S. aureus (MIC: 2.5 mg/mL) and E. coli (MIC: 5 mg/mL). X. venustula was fractionated and tested for to determine its antibacterial activity. Fractions XvFr1 to 5 displayed bioactivities against both test bacteria. Selected crude extracts and fractions were subjected to metabolomics analyses using high-resolution LC–MS. Multivariate analyses showed the presence of five secondary metabolites unique to bioactive fractions XvFr1 to 3, which were identified as responsible for the antibacterial activity of X. venustula. The p-values of these metabolites were at the margin of significance level, with methyl xylariate C (P_60) being the most significant. However, their high variable importance of projection (VIP) scores (>5) suggest these metabolites are potential diagnostic metabolites for X. venustula for “dual” bioactivity against S. aureus and E. coli. The statistical models also showed the distinctiveness of metabolites produced by lichens and ELF, thus supporting our hypotheses of ELF functionality similar to plant endophytes.

Soils can influence climate by sequestering or emitting greenhouse gases (GHG) such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). We are far from understanding the direct influence of cryptogamic covers on soil GHG fluxes, particularly in areas free of potential anthropogenic confounding factors. We assessed the role of well-developed cryptogamic covers in soil attributes, aswell as in the in-situ exchange of GHG between Antarctic soils and the atmosphere during the austral summer. We found lower values of soil organic matter, total organic carbon, and total nitrogen in bare areas than in soils covered by mosses and, particularly, lichens. These differences, together with concomitant decreases and increases in soil temperature and moisture, respectively, resulted in increases in in-situ CO2 emission (i.e. ecosystem respiration) and decreases in CH4 uptake but no significant changes inN2O fluxes. We found consistent linear positive and negative relationships between soil attributes (i.e. soil organic matter, total organic carbon and total nitrogen) and CO2 emissions and CH4 uptake, respectively, and polynomial relationships between these soil attributes and net N2O fluxes. Our results indicate that any increase in the area occupied by cryptogams in terrestrial Antarctic ecosystems (due to increased growing season and increasingly warming conditions) will likely result in parallel increases in soil fertility aswell as in an enhanced capacity to emit CO2 and a decreased capacity to uptake CH4. Suchchanges,unless offset by parallel C uptake processes, would represent a paradigmatic example of a positive climate change feedback. Further, we show that the fate of these terrestrial ecosystems under future climate scenarios, as well as their capacity to exchange GHG with the atmosphere might depend on the relative ability of different aboveground cryptogams to thrive under the new conditions.

Psammophilous grassland communities of inland dunes often occurring together with common juniper scrub are among the most threatened habitat types in Central Europe. Once they were related to disturbance caused by traditional agriculture and forest management (sheep grazing, burning, litter raking and overexploitation of forests). Currently, after the above-mentioned drivers have disappeared, those communities are subjected to secondary succession leading to loss of their typical biodiversity, an important component of which are cryptogams (bryophytes and lichens). In the presented study we ask whether the recently increasing off-road activity, concentrated in dune areas, can maintain such habitats and their biodiversity or instead leads to an even faster deterioration. To answer this question, we studied the cryptogam diversity in an off-road disturbed inland dune environment of a seldom used military training area located in Central Poland. A set of vegetation samples was collected, together with a range of measured or estimated variables including soil parameters, off-road disturbance intensity and factors related to ecological succession, like common juniper scrub cover. The obtained results suggest that highest off-road intensity led to a transformation of the habitat into its very initial stage with active dune processes, while within undisturbed patches the succession led to the development of initial pine forest. The highest number of lichen and bryophyte species occurred within not or only slightly disturbed habitats. However, lichens preferred less shrub cover than bryophytes. Nevertheless, pioneer, typical psammophilous grassland species, which also include some threatened lichen species, benefited from small to medium disturbance intensity. Diverse and spatially complex off-road activity increases the number of microhabitats and can thus be a positive factor promoting the coexistence of all ecological groups of cryptogams connected with the acid inland dune environment. In our opinion, off-road activity may to some extent be used as an inexpensive nature conservation tool in order to maintain open, cryptogam-rich dune habitats.

Over the past decades, outdoor recreation in mountains has become progressively more important and as a result human induced potential damage has increased. Alpine communities are particularly susceptible to human recreational activities, such as tourist trampling. Although there are a number of studies that explicitly assess the effects of trampling on alpine communities, they do not reflect on terrains with a rich topography and the presence of more communities in very small areas. In this study, effects of short-term trampling on some alpine communities in the Tatras, the highest mountains of the Carpathians, were studied experimentally. Vulnerability to disturbance was compared among plant communities in terms of resistance and resilience, which are based on cover measurements. With proximity to trampling intensity, we found a significant decrease in plant cover and abundance of deciduous shrubs, lichens, and mosses. These results demonstrate that human trampling in alpine communities has major negative impacts on lichen and moss abundance and species richness. A short-term trampling experiment required several years of community regeneration. Therefore, management plans should discourage hiking activity off paths and restrict recreational activities. Keywords: tourist trampling; alpine vegetation; Tatras; resistance of vegetation.

Lichens are complex symbiotic association of mycobionts, photobionts, and bacteriobionts, including chemolithotropic bacteria. In the present study, 46 lichenized bacteria were isolated by conventional and enrichment culture methods on nitrogen-free bromothymol blue (NFb) medium. Only 11 of the 46 isolates fixed nitrogen on NFb and had reduced acetylene. All these 11 isolates had also produced siderophore and 10 of them the IAA. Further, ammonia production was recorded from nine of these nitrogen fixers (NF). On molecular characterization, 16 S rRNA sequencing recorded that, nine NF belonged to Proteobacteria, within Gammaproteobacteria, and were closely related to Enterobacter sp. with a maximum similarity to Enterobacter cloacae. Each one of our NF isolates was aligned closely to Enterobacter pulveris strain E443, Cronobacter sakazakii strain PNP8 and Providencia rettgeri strain ALK058. Notably, a few strains we examined found to possess plant growth promoting properties. This is the first report of Enterobacter sp. from lichens which may be inhabit lichen thalli extrinsically or intrinsically.

The lichen flora of the Pinus × rotundata wooded peat bog „Bayerische Au“ in the Austrian part of the Bohemian Forest was examined. 125 species of lichenized ascomycetes and 21 lichenicolous fungi demonstrate that this small area is a hotspot of the Austrian lichen flora, especially due to the presence of exclusively acidic substrats (peat, rich abundance of dead needlewood with rich communities of pin-stalked lichens and other deadwood or peat dwellers). Burgoa angulosa and Chaenotheca sphaerocephala are new to the Austrian species list. Biatora vacciniicola and Chaenotheca laevigata are first records for Upper Austria.

This review presents compiled results of complex biomonitoring studies that have been conducted in the Holy Cross Mountains, southcentral part of Poland, since the 1990s. The significance of these studies results from several aspects: (i) a number and a variety of plant organisms used, e.g., mosses, lichens, coniferous and deciduous trees, and their tissues (wood, bark, needles, leaves, the aboveground parts of several vascular plants); (ii) applications of a broad scope of instrumental methods aiming at determining major and trace elements (including rare earth elements), organic compounds (PAHs, PCBs, phenols), and stable sulfur isotopes (δ34S); and (iii) different methodological and environmental issues addressed. The comparison and interpretation of results derived from seventeen sampling campaigns carried out between 1994 and 2017 are a valuable source of information on the following: (i) bioaccumulative properties of organisms used in air quality monitoring, (ii) identification and variations of local and regional pollution sources and geochemical landscape patterns and processes over years, and (iii) establishing environmental factors that variously affected chemical composition of plants growing under physiological stress, including roadside vegetation and plants from acid mine drainage areas.

Biocrusts play critical eco-functions in many drylands, however it is challenging to explore their community assembly, particularly within patched successional types and across climate zones. Here, different successional biocrusts (alga, lichen, and mossdominated biocrusts) were collected across the northern China, and assembly of biocrust microbial communities was investigated by high-throughput sequencing combined with measurements of soil properties and microclimate environments. Bacterial and eukaryotic communities showed that the maximum and minimum community variation occurred across longitude and latitude, respectively. In the regions where all three stages of biocrusts were involved, the highest community difference existed between successional stages, and decreased with distance. The community assembly was generally driven by dispersal limitation, although neutral processes have controlled the eukaryotic community assembly in hyperarid areas. Along the succession, bacterial community had no obvious patterns, but eukaryotic community showed increasing homogeneity, with increased species sorting and decreased dispersal limitation for community assembly. Compared to early successional biocrusts, there were higher microbial mutual exclusions and more complex networks at later stages, with distinct topological features. Correlation analysis further indicated that the balance between deterministic and stochastic processes might be mediated by aridity, salinity, and total phosphorus, although the mediations were opposite for bacteria and eukaryotes.

The principal etiological agent of human dental caries, Streptococcus mutans is a multi-virulent pathogen that can transform commensal oral microbial community to plaque biofilms. Major virulence factors that are associated with the cariogenicity of S. mutans include adhesion, acidogenicity and acidurity. All these pathogenic traits coordinate and alter the dental plaque ecology which provide room for interaction with other similar acidogenic and aciduric bacteria. This cariogenic flora increases the possibility of enamel demineralization which headway to caries development. The present study was aimed at evaluating the antimicrobial and antiinfective potential of a lichen secondary metabolite usnic acid (UA) against S. mutans. Minimum inhibitory concentration (MIC), Minimum bactericidal concentration (MBC) and growth kinetics were evaluated to determine the antimicrobial potential of UA against S. mutans. UA at 5 μg mL−1 and 10 μg mL−1 concentration were considered as MIC and MBC respectively. Effect on biofilm formation was microscopically assessed and found to be reduced in a concentration dependent manner. Gene expression of gtfB, gtfC, gtfD, vicR, ComDE and smu0630 was found to be downregulated upon treatment with sub-MIC of UA. Acidogenicity, acidurity, eDNA synthesis and response to oxidative stress were found to be attenuated by the influence of UA. It was also demonstrated to act on preformed mature biofilm of S. mutans. Moreover, UA was shown to possess very low frequency to acquire spontaneous resistance development in S. mutans. Besides, no morphological aberrations or toxic effect was instigated by UA in the human buccal epithelial cells as well as to the oral commensals. Altogether, these results demonstrate the therapeutic potential of usnic acid in the treatment of S. mutans infection.

The aim of this study was to assess if lichens (Flavoparmelia caperata) surrounding a landfill dumping site in Italy accumulated higher amounts of microplastics compared with lichens at more distant sites. Lichen samples were collected at three sites along a transect from the landfill: close (directly facing the landfill), intermediate (200 m), and remote (1500 m). Anthropogenic microparticles (fibres and fragments) were determined visually after wet peroxide digestion of the samples, and microplastics were identified based on a hot needle test; the type of plastic was identified by micro-Raman analysis. The results showed that lichens collected in the vicinity of the landfill accumulated the highest number of anthropogenic microfibres and fragments (147 mp/g dw), and consequently microplastics (79 mp/g dw), suggesting that the impact of landfill emissions is spatially limited. The proportion of fibres and fragments identified as microplastics was 40% across all sites and the most abundant polymer type was polyester or polyethylene terephthalate (68%). These results clearly indicated that lichens can effectively be used to monitor the deposition of microplastics.

We explored the infuence of climatic factors on diversity patterns of multiple taxa (lichens, bryophytes, and vascular plants) along a steep elevational gradient to predict communities’ dynamics under future climate change scenarios in Mediterranean regions. We analysed (1) species richness patterns in terms of heat-adapted, intermediate, and cold-adapted species; (2) pairwise beta-diversity patterns, also accounting for its two diferent components, species replacement and richness diference; (3) the infuence of climatic variables on species functional traits. Species richness is infuenced by diferent factors between three taxonomic groups, while beta diversity difers mainly between plants and cryptogams. Functional traits are infuenced by diferent factors in each taxonomic group. On the basis of our observations, poikilohydric cryptogams could be more impacted by climate change than vascular plants. However, contrasting species-climate and traits-climate relationships were also found between lichens and bryophytes suggesting that each group may be sensitive to diferent components of climate change. Our study supports the usefulness of a multitaxon approach coupled with a species traits analysis to better unravel the response of terrestrial communities to climate change. This would be especially relevant for lichens and bryophytes, whose response to climate change is still poorly explored.

Sticta is a subcosmopolitan genus most diverse in the tropics. Traditionally, many taxa were considered to be widespread and morphologically variable, following broadly circumscribed morphodemes. Among these is the S. weigelii morphodeme, characterized by a cyanobacterial photobiont and rather narrow, flabellate to truncate or tapering lobes producing predominantly marginal isidia. Molecular phylogenetic analyses focusing on the ITS fungal barcoding marker revealed that this morphodeme represents several species, some of which are only distantly related to each other. Here we describe two species and one subspecies of this morphodeme as new to science, based on analysis of 400 specimens, for 344 of which we generated ITS barcoding data. The two new species, S. andina and S. scabrosa, are broadly distributed in the Neotropics and also found in Hawaii, where the latter is represented by the new subspecies, S. scabrosa subsp. hawaiiensis; in the case of S. andina, the species is also found in the Azores. Sticta andina exhibits high phenotypic variation and reticulate genetic diversification, whereas the phenotypically rather uniform S. scabrosa contains two main haplotypes, one restricted to Hawaii. Sticta andina occurs in wellpreserved montane to andine forests and paramos, whereas the two subspecies of S. scabrosa are found in tropical lowland to lower montane forests, tolerating disturbance and extending into anthropogenic habitats. Key words: Ascomycota, Azores, Hawaii, Neotropics, Peltigeraceae, Sticta, Sticta weigelii.

Polybrominated diphenyl ethers (PBDEs) have widely been used for decades as flame retardants in a variety of products like plastics for building insulation, upholstered furniture, electrical appliances, vehicles, aircrafts, polyurethane foams, textiles, cable insulation, appliance plugs and various technical plastics in concentrations of 5–30%. However, PBDEs also act as endocrine disrupters, neurotoxins, and negatively affect fertility. In 2001, worldwide consumption of technically relevant penta-BDEs was still estimated at 7500 tons, octa-BDEs at 3790 tons, and deca-BDE at 56,100 tons, but 50–60% of this total volume are discharged into the environment via sewage sludge and its agricultural use alone. In addition, soils are ubiquitously contaminated by the gaseous or particle-bound transport of PBDEs, which today has its main source in highly contaminated electronic waste recycling sites. The emitted PBDEs enter the food chain via uptake by the plants’ roots and shoots. However, uptake and intrinsic transport behaviour strongly depend on crop specifics and various soil parameters. The relevant exposure and transformation pathways, transport-relevant soil and plant characteristics and both root concentration factors (RCF) and transfer factors (TF) as derivable parameters are addressed and quantified in this review. Finally, a simple predictive model for quantification of RCF and TF based on log KOW values and the organic content of the soil/lipid content of the plants is also presented.

Cloud forests have been found to lose more nitrogen in stream discharge than they gain from atmospheric deposition. They also support a large diversity and biomass of tree epiphytes, predominately composed of cryptogams. Since cryptogam epiphytes harbor nitrogen fixing cyanobacteria, they may help make up for the nitrogen loss from ecosystems. We assessed cryptogam biomass on the ground, boles and branches in Quercus costaricensis dominated stands near the tree line in the Cordillera de Talamanca, Costa Rica. Nitrogen fixation was assayed using 15N2 uptake. Total cryptogam biomass was 2 977 kg ha−1, with 67% being found on the lower branches. Bryophytes and chlorolichens made up 53% and 44%, respectively, of the biomass. Half of the bryophyte mass was composed of the liverwort Plagiochila heterophylla, and 66% of the chlorolichen of Lobariella pallida. There were no significant differences in nitrogen fixation rates between the cryptogam species, with a mean rate of 5.04 µg N g−1 day−1 during the predominantly wet condition in the forest. The overall nitrogen input from fixation was 6.1 kg N ha−1 year−1, of which 78% came from bryophytes, 18% from chlorolichens, and 4% from cyanolichens. Only 2.0% of the fixation occurred in cryptogams on the ground, whereas 67%, 24%, and 7% occurred on the lower branches, boles, and upper branches, respectively. These results show that tree epiphytes constitute a significant source of nitrogen for these forests, due to the trees’ large surface area, and can make up for the nitrogen lost from these ecosystems.

Using 642 forest plots from three regions in Germany, we analyzed the direct and indirect effects of forest management intensity and of environmental variables on lichen functional diversity (FDis). Environmental stand variables were affected by management intensity and acted as an environmental filter: summing direct and indirect effects resulted in a negative total effect of conifer cover on FDis, and a positive total effect of deadwood cover and standing tree biomass. Management intensity had a direct positive effect on FDis, which was compensated by an indirect negative effect via reduced standing tree biomass and lichen species richness, resulting in a negative total effect on FDis and the FDis of adaptation-related traits (FDisAd). This indicates environmental filtering of management and stronger niche partitioning at a lower intensity. In contrast, management intensity had a positive total effect on the FDis of reproduction-, dispersal- and establishment-related traits (FDisRe), mainly because of the direct negative effect of species richness, indicating functional over-redundancy, i.e., most species cluster into a few over-represented functional entities. Our findings have important implications for forest management: high lichen functional diversity can be conserved by promoting old, site-typical deciduous forests with a high richness of woody species and large deadwood quantity.

Terricolous lichen communities in lowlands occur especially in open dry habitats. Such communities are often dominated by species of the genus Cladonia, which are very variable in morphology, reproduction strategies, and secondary metabolites. In this work, we investigated traits-environment relationships considering vegetation dynamics, substrate pH, disturbance, and climate. A total of 122 plots were surveyed in 41 acidic dry grasslands in the western Po Plain (Northern Italy). Relationships between Cladonia traits and environmental variables were investigated by means of a model-based Fourth Corner Analysis. Thallus morphology and metabolites responded to vegetation dynamics, substrate pH, disturbance, and climate, whereas reproduction strategies responded only to vegetation dynamics. Traits’ correlations with vegetation dynamics elucidate their colonization patterns in open dry habitats or suggest biotic interactions with bryophytes and vascular plants. In addition, correlations between metabolites and environmental factors support interpretations of their ecological roles. Our results also stress the importance of studying traits’ relationships with climatic factors as an alert towards lichen reactions to climate change. Keywords: lichens; open dry habitats; reproduction strategy; secondary metabolites; species traits; thallus growth forms; vegetation dynamics.

Dry sand grasslands on inland dunes in the Lower-Middle Elbe Valley between Dömitz and Boizenburg. This paper deals with the flora and vegetation of dry sand grasslands of three large inland dunes east of the river in the Elbe basin between Dömitz and Boizenburg. The Spergulo-Corynephoretum occurs everywhere on open sandy sites out of the reach of ground- water and of the high-water level of the river. The soils show low contents of humus and low pH values. The dune slopes near Gothmann and especially those near Klein Schmölen show a distinct zonation pattern from open Corynephorus canescens communities on the top to dense grassland communities on the lower slopes, which are influenced by groundwater or by the high-water level of the river. The following sequence could be distinguished: 1) The Koeleria glauca-Carex arenaria community (Corynephorion canescentis) on relatively dry top and upper slope; 2) a Cladonia rangiformis-Rumex acetosella community (Koelerio-Corynephoretea) next downslope; 3) a Sedum reflexum-Hypnum cupressiforme community further downslope, and finally 4) an Allium angulosum-Sedum sexangulare community and the Diantho deltoides-Armerietum elongatae (Armerion elongatae) at the foot of the slope. This vegetation zonation coincides with increasing pH values, C contents and moisture of the soil. Small-scale differences in vegetation pattern and vegetational transitions are described in terms of variants and lower units. Transect analyses illustrate in detail the vegetation sequence in relation to soil conditions. Keywords: Dry sand grassland, dunes, Elbe basin, Koelerio-Corynephoretea, lichen synusiae, soil gradient, transect analysis.

Heathland near the town of Munster: a floristical and phytosociological study as a basis for management and amelioration. - This paper deals with flora and vegetation of four heathland areas in the immediate vicinity of the town of Munster (Soltau-Fallingbostel), Lower Saxony. The study also formulates a management plan for preservation and amelioration of the heathlands. The field work was carried out in 1991. The vegetation research followed the concepts of the Braun-Blanquet approach. The plant communities are described, with main emphasis on Nardo-Callunetea communities. Vegetation tables are included. Genisto-Callunetum cladonietosum is very common. Koelerio-Corynephoretea and Scheuchzerio-Caricetea communities, which are typical for heathlands, are also dealt with. Locally ruderal Plantaginetea majoris communities occur, mainly on sites disturbed by trampling. Moreover, a survey is presented of the synusiae of lichens and bryophytes. The lichen synusiae are rich in Cladonia species and are well developed. Species lists of vascular plants, lichens and bryophytes are given for each heathland area, with comments on their status. For some community types data are included on pH, conductivity and C/N ratio. Heathland management is surveyed and discussed. Réintroduction of sheep-grazing, combined with sod-cutting and mowing, is recommended as the most appropriate management measure. However, this form of management does not seem realistic for the area. Thus for each heathland area a detailed management plan has been worked out, which includes maps indicating sites where management measures should be implemented. Small-scale sodcutting and mowing are recommended and results should be evaluated annually. Cutting of adjacent Scots pines is recommended in order to enlarge the heathland areas.

The pine forests on sandy soils (Dicrano-Pinion) in the northern German lowlands: Syntaxonomic, edaphic and geographic differentiation. The phytosociology of Scots pine forests on sandy soils in the lowlands of northern Germany is reevaluated on the basis of 1.096 relevés. It is shown that not only pine forests in north-eastern Germany, but also the pine forests of poor sandy soils in north-western Germany, belong to the Dicrano-Pinion Matuszk. 1962 em. hoc loco (Piceetalia abietis, Vaccinio-Piceetea). Thus, the range of this alliance extends westwards from that of the natural pine forests, i.e. those existing before the destruction of forests by man. Scots pine dominance always results in rather uniform environmental conditions. Thus, over the entire range, all Scots pine forests are rather similar. Natural old-growth pine forests, spontaneous pioneer pine woods in formerly open landscapes, and afforestations on decidious forest stands, cannot be distinguished floristically. Within the Dicrano-Pinion alliance four associations (Cladonio-Pinetum, Leucobryo-Pinetum, Empetro nigri-Pinetum, Peucedano-Pinetum) and one community (Deschampsia flexuosa-Pinus sylve- stns-community) are distinguished. The widespread Cladonio-Pinetum, Leucobryo-Pinetum and Deschampsia-Pinus community are differentiated along an ecological gradient of increasing nutrient supply. All three communities are subdivided multidimensionally according to climatic and edaphic factors. Empetro-nigri-Pinetum and Peucedano-Pinetum, which are represented only by few relevés, are characteristic of base-rich habitats with sandy soils. Consequently they are rare in the northern German pleistocenic regions. Pine forests on peaty soil, classified by many authors into the Dicrano-Pinion, are excluded from this alliance. Keywords: Cladonio-Pinetum, Dicrano-Pinion, Empetro nigri-Pinetum, Leucobryo-Pinetum, northern Germany, Peucedano-Pinetum, phytosociology, Scots pine forest, synchorology.

In 1992 and 1993, the heathland vegetation on the East Frisian Islands (North- West-Germany), that is dominated by Empetrum nigrum L. was analyzed according to the Braun-Blanquet approach. All of the examined heaths belong to the Carici arenariae- Empetretum Tx. et Kawamura 1975 (Empetrion boreale, Nardo-Callune- tea). On the basis of 517 vegetation relevés the association is divided into four subassociations, namely the C.-E. festucetosum *arenariae Dierssen ex Mühl 1993, the C.-E. typicum de Smidt 1977, the C.-E. caricetosum nigrae Mühl 1993, and the C.-E. ericetosum de Smidt 1977.

Terricolous lichen- and moss-synusiae were studied in dry heathlands in the western European Lowlands. Four types are dealt with. The pioneer Placynthiella uliginosa synusium occurs on open, humic soil. It is succeeded by the Placynthiella-Cladonia glauca synusium. In older, dry heath the Cladinaportentosa synusium occurs. In moist and old heath the Hypnum-Pleurozium schreheri synusium is found. The species-rich Cladina portentosa synusium is common in the Lüneburger Heide. The occurrence of the synusia could be related to the age of the heathland. The dominance of Campylopus introflexus is discussed, just as synusial succession. Finally changes in the lichen- and mossflora of dry heathlands during this century are briefly discussed.

Molecular genetic analysis on the occurrence of reindeer lichen Cladonia stygia in Hesse [in German with English summary:] A survey conducted in 2009 reported the reindeer lichen Cladonia stygia (Fr.) Ruoss for the first time in Hesse. This species is often difficult to distinguish from the morphologically similar C. rangiferina (L.) F. H. Wigg., and its identification remains uncertain. We therefore used molecular genetic data to identify the Hessian samples of this species. Phylogenetic pedigrees based on six mitochondrial and nuclear gene loci support the distinction of C. stygia from C. rangiferina. Only two out of seven populations reported in Hesse consist of C. stygia. The other populations are formed by C. rangiferina. A targetted search for C. stygia and verification of its identification using molecular genetics are necessary steps for reliably judging the conservational status of this species in Hesse.

Two epiphytic lichens (Xanthoria alfredii, XAa; X. ulophyllodes, XAu) and soil were sampled at three sites with varied distances to a road in a semiarid sandland in Inner Mongolia, China and analyzed for concentrations of 42 elements to assess the contribution of soil input and road trafc to lichen element burdens, and to compare element concentration diferences between the two lichens. The study showed that multielement patterns, Fe:Ti and rare earth element ratios were similar between the lichen and soil samples. Enrichment factors (EFs) showed that ten elements (Ca, Cd, Co, Cu, K, P, Pb, S, Sb, and Zn) were enriched in the lichens relative to the local soil. Concentrations of most elements were higher in XAu than in XAa regardless of sites, and increased with proximity to the road regardless of lichen species. These results suggested that lichen element compositions were highly afected by soil input and road trafc. The narrow-lobed sorediate species were more efcient in particulate entrapment than the broad-lobed nonsorediate species. XAa and XAu are good bioaccumulators for road pollution in desert and have similar spatial patterns of element concentrations for most elements as response to road trafc emissions and soil input.

Heterodermia hypoleuca (Ach.) Trevis., H. japonica (M. Sato) Swinscow & Krog and H. subascendens (Asahina) Trass. have been recorded for the first time in Mongolia. Data on substrates, habitats, distribution are listed for every species. Taxonomic comments and distinctive characters are provided for these species. The habitats are briefly described and the frequently associated species are listed. It is interesting to note that as a result of processing hundreds of herbarium collections of lichens, numerous new species were found in Mongolia. This means that there is still a substantial gap in the knowledge, especially about the lichen flora of remote corners of the country, which are numerous. Keywords: lichen species; Heterodermia; Mountain Range; mossed granite rocks.

The present study provides new data concerning the chemical characterisation of Physcia mediterranea Nimis, a rare Mediterranean species belonging to the family Physciaceae. The phytochemical screening was carried out using GC‐MS, HPLC‐ESI‐MS‐MS, and NMR techniques. Hot extraction of n‐hexane was carried out, followed by separation of the part insoluble in methanol: wax (WA‐hex), from the part soluble in methanol (ME‐hex). GC‐MS analysis of the ME‐hex part revealed the presence of methylbenzoic acids such as sparassol and atraric acid and a diterpene with a kaurene skeleton which has never been detected before in lichen species. Out of all the compounds identified by HPLC‐ESI‐MS‐MS, sixteen compounds are common between WA‐hex and ME‐hex. Most are aliphatic fatty acids, phenolic compounds and depsides. The wax part is characterised by the presence of atranorin, a depside of high biological value. Proton 1H and carbon 13C NMR have confirmed its identification. Atranol, chloroatranol (depsides compound), Ffukinanolide (sesquiterpene lactones), leprolomin (diphenyl ether), muronic acid (triterpenes), and ursolic acid (triterpenes) have also been identified in ME‐hex. The results suggested that Physcia mediterranea Nimis is a valuable source of bioactive compounds that could be useful for several applications as functional foods, cosmetics, and pharmaceuticals. Keywords: Algerian lichen; Physcia mediterranea Nimis; bioactive compounds; n‐hexane extract; wax; GC‐MS; HPLC‐ESI‐MS‐MS; NMR.

Oxidative stress, mitochondrial dysfunction, and neuroinflammation are strongly associated with the pathogenesis of Parkinson’s disease (PD), which suggests that anti-oxidative and anti-inflammatory compounds might provide an alternative treatment for PD. Here, we evaluated the neuroprotective effects of evernic aid (EA), which was screened from a lichen library provided by the Korean Lichen Research Institute at Sunchon National University. EA is a secondary metabolite generated by lichens, including Ramalina, Evernia, and Hypogymnia, and several studies have described its anticancer, antifungal, and antimicrobial effects. However, the neuroprotective effects of EA have not been studied. We found that EA protected primary cultured neurons against 1- methyl-4-phenylpyridium (MPP+)-induced cell death, mitochondrial dysfunction, and oxidative stress, and effectively reduced MPP+-induced astroglial activation by inhibiting the NF-κB pathway. In vivo, EA ameliorated MPTP-induced motor dysfunction, dopaminergic neuronal loss, and neuroinflammation in the nigrostriatal pathway in C57BL/6 mice. Taken together, our findings demonstrate that EA has neuroprotective and anti-inflammatory effects in PD models and suggest that EA is a potential therapeutic candidate for PD.

Widespread geographic distributions in lichens have been usually explained by the high dispersal capacity of their tiny diaspores. However, recent phylogenetic surveys have challenged this assumption and provided compelling evidence for cryptic speciation and more restricted distribution ranges in diverse lineages of lichenforming fungi. To evaluate these scenarios, we focus on the fungal genus Pseudephebe (Parmeliaceae) which includes amphitropical species, a distribution pattern whose origin has been a matter of debate since first recognized in the nineteenth century. In our study, a six-locus dataset and a broad specimen sampling covering almost all Earth’s continents is used to investigate species delimitation in Pseudephebe. Population structure, gene flow and dating analyses, as well as genealogical reconstruction methods, are employed to disentangle the most plausible transcontinental migration routes, and estimate the timing of the origin of the amphitropical distribution and the Antarctic populations. Our results demonstrate the existence of three partly admixed phylogenetic species that diverged between the Miocene and Pliocene, and whose Quaternary distribution has been strongly driven by glacial cycles. Pseudephebe minuscula is the only species showing an amphitropical distribution, with populations in Antarctica, whereas the restricted distribution of P. pubescens and an undescribed Alaskan species might reflect the survival of these species in European and North American refugia. Our microevolutionary analyses suggest a Northern Hemisphere origin for P. minuscula, which could have dispersed into the Southern Hemisphere directly and/or through “mountain-hopping” during the Pleistocene. The Antarctic populations of this species are sorted into two genetic clusters: populations of the Antarctic Peninsula were grouped together with South American ones, and the Antarctic Continental populations formed a second cluster with Bolivian and Svalbard populations. Therefore, our data strongly suggest that the current distribution of P. minuscula in Antarctica is the outcome of multiple, recent colonizations. In conclusion, our results stress the need for integrating species delimitation and population analyses to properly approach historical biogeography in lichenforming fungi.

Mycobionts of many lichen genera appear to demonstrate strong selectivity in the choice of algal partner. The biological properties of a photobiont and its availability in an environment significantly determine the habitat requirements of lichens. Flexibility in photobiont choice extends the ecological amplitude of lichens; therefore, it may constitute an important adaptive strategy for colonization of extreme habitats. The photobiont inventory of the three epigeic lichens most resistant to soil pollution, i.e., Cladonia cariosa, C. rei, and the hyperaccumulator Diploschistes muscorum, was examined to verify whether and to what extent algal composition depends on the type of habitat and substrate enrichment with heavy metals. Photobionts Asterochloris and Trebouxia were identified in the studied lichen species; however, the presence of Trebouxia was directly related to anthropogenic sites with technogenic substrates, and the proportion of lichen specimens with these algae clearly depended on the level of heavy-metal soil pollution and the habitat type. The total number of algal haplotypes increased with increasing soil pollution, and the richness was associated more with soil pollution than with a given lichen species. Additionally, a large number of lichen individuals bearing multiple algal genotypes at polluted sites were recorded. Although Cladonia lichens were previously thought to be restricted to Asterochloris, they are able to start the relichenization process with Trebouxia under specific habitat conditions and to establish a stable association with these algae when colonization of disturbed sites takes place. Comparative analysis of the internal transcribed spacer (ITS) rDNA sequences revealed as many as 13 haplotypes of Trebouxia, and phylogenetic analysis grouped them into two different clades. Such a high level of genetic diversity indicates that Trebouxia is well adapted to metal pollution and could be an alternative photosynthetic partner for certain lichens, especially in polluted sites.

The novel biologically active molecules could play a significant role in the treatment of human diseases. Natural products have been and continue to be a major source of pharmaceuticals, and lichen secondary metabolites emerge as never-ending potential for bioactive molecules with a variety of pharmacological activities. Polyketides, which are synthesized by enzymes encoded by PKS genes, constitute the major group of these secondary metabolites. To date, there is a lack of information about identification of PKS gene modules. Functional validation studies in lichens are difficult because of the slow growth rates of lichens, the symbiotic partners of lichens cannot be cultured in the laboratory or the fact that most of them cannot be grown in culture. Consequently, the importance of genomic mining approach is increasing as a unique tool for natural product discovery studies. Here, we bioinformatically investigated the type I PKS module candidates in nine publicly available lichen-forming fungi genomes through the use of the in silico screening tools. We also predicted putative secondary metabolites produced in these lichens which indicated the pharmaceutical potential of these nine lichen-forming fungi by bioinformatics tools. Keywords: Fungi; lichen; bioinformatics; PKS; secondary metabolite.

Molecular identifcation methods, in particular high-throughput sequencing tools, have greatly improved our knowledge about fungal diversity and biogeography, but many of the recovered taxa from natural environments cannot be identifed to species or even higher taxonomic levels. This study addresses the phylogenetic placement of previously unrecognized fungal groups by using two complementary approaches: (i) third-generation amplicon sequencing analysis of DNA from global soil samples, screening out ITS reads of<90% similarity to other available Sanger sequences, and (ii) analysis of common fungal taxa that were previously indicated to be enigmatic in terms of taxonomic placement based on the ITS sequences alone (so-called top50 sequences). For the global soil samples, we chose to amplify the full rRNA gene operon using four partly overlapping amplicons and multiple newly developed primers or primer combinations that cover nearly all fungi and a vast majority of non-fungal eukaryotes. We extracted the rRNA 18S (SSU) and 28S (LSU) genes and performed phylogenetic analyses against carefully selected reference material. Both SSU and LSU analyses placed most soil sequences and top50 sequences to known orders and classes, but tens of monophyletic groups and single sequences remained outside described taxa. Furthermore, the LSU analyses recovered a few small groups of sequences that may potentially represent novel phyla. We conclude that rRNA genes-based phylogenetic analyses are efcient tools for determining phylogenetic relationships of fungal taxa that cannot be placed to any order or class using ITS sequences alone. However, in many instances, longer rRNA gene sequences and availability of both SSU and LSU reads are needed to improve taxonomic resolution. By leveraging third-generation sequencing from global soil samples, we successfully provided phylogenetic placement for many previously unidentifed sequences and broadened our view on the fungal tree of life, with 10–20% new order-level taxa. In addition, the PacBio sequence data greatly extends fungal class-level information in reference databases.
