The cephalolichen Peltigera aphthosa (L.) Willd. is characterized by lateral heterogeneity, which manifests itself in the presence of three thallus zones, referred to as the apical, basal and medial zone. These zones differ in terms of interaction between lichen bionts and their physiological activity. The apical thallus zone is more efﬁcient in establishing a contact with cyanobacteria, because of a higher lectin content and a larger overall thallus surface area due to the presence of numerous mycobiont hyphae. Cephalodia are formed in this zone. The interaction between the mycobiont and cyanobiont is more intense in the medial zone. However, the establishment of the contact with cyanobacteria in this zone less probable. The spatial distribution of lectins in the thallus was determined. To reveal the differences in photosynthetic activity in three thallus zones, transient analysis of chlorophyll a ﬂuorescence and the assessment of non-photochemical quenching of excited chlorophyll states were performed. Assimilation of absorbed light energy was more effective in the medial zone. The basal zone was characterized by decreased photosynthetic activity, lichen dissociation and thallus death.

Lichen secondary metabolites (LSMs) are regarded with interest for valuable biological properties, but chemical variability among/within lichen taxa has been only fragmentarily characterized by advanced analytical techniques. Knowledge of variability at a local geographic scale has been particularly neglected, while it should address the collection of chemically homogeneous materials to test and exploit LSMs. Here we evaluated the chemical variability of 48 Xanthoparmelia specimens from two rock outcrops in Western Italian Alps, representative of nine morphotypes and sixteen rDNA ITS haplotypes. Qualitative and quantitative analyses were performed by HPLC-DAD-ESI-MS2 and UPLC-HDR-DAD, respectively, and revealed the occurrence of 18 LSMs. Chemical partition allowed distinguishing six chemical groups, only partially overlapping with distinct morphotypes and three divergent haplotype groups, which, overall, accounted for the co-occurrence of different taxa only in part identifiable with species described for Europe. Some morphotypes were variable in presence and concentration of LSMs, and chemical divergences also characterized single ITS haplotypes. Accordingly, the collection of chemically homogeneous materials, even at a local scale, may be not properly addressed by morphological features and ITS barcoding, and should be confirmed by a specimen-level chemical characterization.

Question: In order to identify the factors and assembly rules which potentially shape natural lichen communities we asked whether these communities are phylogenetically and functionally structured along an environmental gradient in beech forests in the Iberian Peninsula. Location: A climatic gradient in the Iberian Peninsula. Methods: We used species inventories, trait data and a molecular dated phylogeny to calculate phylogenetic and functional community metrics. We examined the phylogenetic and functional diversity of epiphytic lichen assemblages in nine beech forests along an environmental gradient. Results: We found a significant pattern in the average phylogenetic and functional diversity across sites. Species at northern sites were less closely related than expected by chance (phylogenetic and functional overdispersion), suggesting that these communities could be structured by species interactions limiting the similarity among them (e.g. by competition and facilitation). In contrast, species occurring in the southern distributional limit of the host tree were phylogenetically and functionally clustered, implying that these communities could be primarily structured by environmental filtering, driven by the reduction of summer rainfall. Lower precipitation areas favoured fruticulose and squamulose species and a larger proportion of species with green algal photobionts and asexual reproduction. Conclusions: Our results suggest that environmental filtering and species interactions regulate lichen communities differently under contrasting environmental conditions in beech forests in the Iberian Peninsula. These processes are reflected by the presence of key lichen traits that are phylogenetically conserved and can provide advantages for competition or adaptation to the environment.

Winter evergreens living in mountainous areas have to withstand a harsh combination of high light levels and low temperatures in wintertime. In response, evergreens can activate a photoprotective process that consists of the downregulation of photosynthetic efficiency, referred to as winter photoinhibition (WPI). WPI has been studied mainly in woody evergreens and crops even when, in many instances, other functional groups such as lichens or bryophytes dominate in alpine and boreal habitats. Thus, we aimed to (1) assess the occurrence of WPI within overwintering evergreens comprising woody species, herbs, mosses and lichens, (2) compare the recovery kinetics among those groups and (3) clarify the role of thylakoid proteins and pigments in both processes: WPI and recovery. With this aim, WPI was analyzed in 50 species in the field and recovery kineticcs were studied in one model species from each functional group. Results showed that high levels of WPI are much more frequent among woody plants than in any other group, but are also present in some herbs, lichens and mosses. Winter conditions almost always led to the de-epoxidation of the xanthophyll cycle. Nevertheless, changes in the de-epoxidation level were not associated with the activation/deactivation of WPI in the field and did not match changes in photochemical efficiency during recovery treatments. Seasonal changes in thylakoid proteins [mainly D1 (photosystem II core complex protein) and PsbS (essential protein for thermal dissipation)] were dependent on the functional group. The results highlight the diversity of physiological solutions and suggest a physical–mechanical reason for the more conservative strategy of woody species compared with other groups.

Lichens occur in most terrestrial ecosystems; they are often present as minor contributors, but in some forests, drylands and tundras they can make up most of the ground layer biomass. As such, lichens dominate approximately 8% of the Earth’s land surface. Despite their potential importance in driving ecosystem biogeochemistry, the influence of lichens on community processes and ecosystem functioning have attracted relatively little attention. Here, we review the role of lichens in terrestrial ecosystems and draw attention to the important, but often overlooked role of lichens as determinants of ecological processes. We start by assessing characteristics that vary among lichens and that may be important in determining their ecological role; these include their growth form, the types of photobionts that they contain, their key functional traits, their water-holding capacity, their colour, and the levels of secondary compounds in their thalli. We then assess how these differences among lichens influence their impacts on ecosystem and community processes. As such, we consider the consequences of these differences for determining the impacts of lichens on ecosystem nutrient inputs and fluxes, on the loss of mass and nutrients during lichen thallus decomposition, and on the role of lichenivorous invertebrates in moderating decomposition. We then consider how differences among lichens impact on their interactions with consumer organisms that utilize lichen thalli, and that range in size from microfauna (for which the primary role of lichens is habitat provision) to large mammals (for which lichens are primarily a food source). We then address how differences among lichens impact on plants, through for example increasing nutrient inputs and availability during primary succession, and serving as a filter for plant seedling establishment. Finally we identify areas in need of further work for better understanding the role of lichens in terrestrial ecosystems. These include understanding how the high intraspecific trait variation that characterizes many lichens impacts on community assembly processes and ecosystem functioning, how multiple species mixtures of lichens affect the key communityand ecosystem-level processes that they drive, the extent to which lichens in early succession influence vascular plant succession and ecosystem development in the longer term, and how global change drivers may impact on ecosystem functioning through altering the functional composition of lichen communities. Key words: decomposition, functional traits, invertebrate food webs, lichenized fungi, nutrient cycling, trophic interactions.

The contributions of non-vascular plants (NVPs) to ecosystem function can be significant in high latitude and high altitude ecosystems and yet their inclusion in trait-based studies is rare. Our aim in this paper is to argue for a more thorough and widespread inclusion of NVPs in trait-based studies of ecosystem function. We focused on three specific objectives, (i) to review and summarize the current knowledge base as to how NVP traits are measured and used in assessing ecosystem function, (ii) to highlight challenges in incorporating vascular plants (VPs) and NVPs together in trait-based studies, and (iii) discuss a framework by which VPs and NVPs can be included in explaining ecosystem function. From a literature search of the Web of Science database we found that the majority of trait-based studies examined mostly vascular plants (VPs), occasionally VPs and NVPs separately, but rarely the two groups together to describe ecosystem function. To date compared to VPs, assessment of the contributions of NVPs to ecosystem function has remained relatively unexplored. Plant communities comprising VPs and NVPs can influence, and in turn be influenced by their habitats. We argue that the response and effect traits of VPs and NVPs are comparable and that classifying NVPs simply as “mosses” and “lichens” and assessing their functions as such is inadequate. We summarized and identified particular measurable traits of both VPs and NVPs that have significant effects on nutrient cycling and community assembly. Future studies in areas where NVPs are abundant should include both VPs and NVPs, aggregated at the finest taxonomic resolution possible to relate ecosystem processes such as cycling of matter and plant community assembly.

Some free-living Ascomycetes and white and brown rot Basidiomycetes can generate hydroxyl radicals using extracellular redox cycling. However, the mechanisms of hydroxyl radical production differ between white and brown rot Basidiomycetes, and are unknown for Ascomycetes. Here, we present a survey of extracellular hydroxyl radical production by a range of lichenized Ascomycetes. Results show that given a quinone and chelated ferric ions, many lichens can readily produce hydroxyl radicals, and this is accompanied by the reduction of Fe3+ to Fe2+. In white rot fungi, extracellular redox enzymes have been proposed to be involved in hydroxyl radical generation. However, a survey of a wide range of lichens suggests that in these fungi hydroxyl radical production does not directly correlate with the activity of laccases and peroxidases. Rather, radicals are probably produced by a mechanism like that proposed for brown rot fungi. Potential roles of hydroxyl radicals produced by lichens include the breakdown of lignocellulosic residues in the soil which may allow lichens to live a partially saprotrophic existence, the breakdown of toxic soil chemicals and the formation of an ‘oxidative burst’ to deter potential pathogens. Keywords: Laccases; Peroxidases; Quinone reductases; Reactive oxygen species; Saprophyte.

(2017): Species- and site-specific efficacy of commercial biocides and application solvents against lichens. - International Biodeterioration and Biodegradation, 123: 127–137.|
Control of lichens on stone cultural heritage is mostly achieved by a combination of mechanical removal with biocide applications. However, there is a lack of scientific evidence on the efficacy of different biocides on different species, and on the consistency of biocide effects on heritage sites in different environmental conditions. This results in some uncertainty when conservation interventions to control lichens are routinely defined on the basis of restoration tradition or empirical evaluation, without experimental measures of how lichens respond. In this work, we quantitatively evaluated (a) the efficacy of five commercially-available biocides, applied using a brush or with a cellulose poultice, against two species (Protoparmeliopsis muralis, Verrucaria nigrescens), and (b) whether the effects on the two species were consistent, per treatment, across three Italian heritage sites. Lichen vitality was quantified through analyses of chlorophyll a fluorescence (ChlaF) and ergosterol content. The results indicated that all the tested biocides, and their organic solvents, affected the vitality of both the species. However, most of treatments displayed different efficacy on each species, across the different sites and between brush and poultice applications. Accordingly, when a conservation intervention to control lichen growth is planned, biocide treatments need both species- and site-specific calibrations and lichen vitality should be properly ascertained in situ by monitoring ChlaF parameters (FV/FM and F0) twenty days after trial biocide applications.

Tree hollows often harbor animals and microorganisms, thereby storing nutritive resources derived from their biological activities. The outflows from tree hollows can create unique microenvironments, which may affect communities of epiphytic organisms on trunk surfaces below the hollows. In this study, we tested whether the species richness and composition of epiphytic bryophytes (liverworts and mosses) and lichens differ above and below tree hollows of Aria japonica and Cercidiphyllum japonicum in a Japanese temperate forest. The species richness of epiphytic bryophytes and lichens did not differ above and below hollows; however, the species composition of bryophytes differed significantly above and below hollows. Indicator species analyses showed that the moss species Anomodon tristis and the liverwort species Porella vernicosa were significantly more common below than above hollows, while the liverwort species Radula japonica and four lichen species, including Leptogium cyanescens, occurred more frequently above than below hollows. Our results highlight that tree hollows can produce unique microenvironments on trunk surfaces that potentially contribute to the maintenance of epiphytic diversity on a local scale.

Climate change is affecting the composition and functioning of ecosystems across the globe. Mountain ecosystems are particularly sensitive to climate warming since their biota is generally limited by low temperatures. Cryptogams such as lichens and bryophytes are important for the biodiversity and functioning of these ecosystems, but have not often been incorporated in vegetation resurvey studies. Hence, we lack a good understanding of how vascular plants, lichens and bryophytes respond interactively to climate warming in alpine communities. Here we quantified long-term changes in species richness, cover, composition and thermophilization (i.e. the increasing dominance of warm-adapted species) of vascular plants, lichens and bryophytes on four summits at Dovrefjell, Norway. These summits are situated along an elevational gradient from the low alpine to high alpine zone and were surveyed for all species in 2001, 2008 and 2015. During the 15-year period, a decline in lichen richness and increase in bryophyte richness was detected, whereas no change in vascular plant richness was found. Dwarf-shrub abundance progressively increased at the expense of lichens, and thermophilization was most pronounced for vascular plants, but occurred only on the lowest summits and northern aspects. Lichens showed less thermophilization and, for the bryophytes, no significant thermophilization was found. Although recent climate change may have primarily caused the observed changes in vegetation, combined effects with non-climatic factors (e.g. grazing and trampling) are likely important as well. At a larger scale, alpine vegetation shifts could have a profound impact on biosphere functioning with feedbacks to the global climate.

Background: Lichens that were used in traditional medicine for ages produce numerous secondary metabolites, however our knowledge about biological activities of substances secreted by separated bionts is scarce. The main objectives of this study were to isolate and find optimal conditions for the growth of mycelia from three common lichen-forming fungi, i.e. Caloplaca pusilla, Protoparmeliopsis muralis and Xanthoria parietina and to evaluate antibacterial and antiproliferative activities of their acetone extracts. Methods: Agar disc diffusion and broth microdilution methods were used to test antimicrobial activity against six species of bacteria. MTT method, flow cytometry assay and DAPI staining were applied to test antiproliferative activity of selected extracts against MCF-7 (human breast adenocarcinoma), PC-3 (human prostate cancer) and HeLa (human cervix adenocarcinoma) cancer cells. Results: P. muralis strongly inhibited the growth of Gram-positive bacteria, i.e. Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus and Staphylococcus epidermidis (MICs from 6.67 to 100.00 μg mL−1). X. parietina grown on PDA and G-LBM media decreased HeLa or MCF-7 cancer cells viability with IC50 values of about 8 μg mL−1, while C. pusilla grown on G-LBM medium showed the highest potency in decreasing MCF-7 (7.29 μg mL−1), PC-3 (7.96 μg mL−1) and HeLa (6.57 μg mL−1) cancer cells viability. We also showed induction of apoptosis in HeLa, PC-3 and MCF-7 cell lines treated with increasing concentrations of C. pusilla extract. Conclusion: We showed that selected acetone extracts demonstrated a strong antimicrobial and anticancer effects that suggests that aposymbiotically cultured lichen-forming fungi can be a source of antibacterial and antiproliferative compounds.

[Translation of Original Russian Text by N. Gorgolyuk © I.N. Mikhailova, 2017, published in Ekologiya, 2017, No. 4, pp. 277–281.] Analysis has been made of changes in the species composition and abundance of epiphytic lichens on fir trees during the first decade after a sharp reduction of emissions from a large copper smelter in the Middle Urals. The results show that lichens have recolonized the area of the former lichen desert and that the abundance of lichen species in the impact and buffer zones has increased. However, a fairly long time is required before lichen communities in the vicinity of the smelter can recover to the background state, since species highly sensitive to pollution still occur only in the background area.

Habitat loss and fragmentation can negatively impact the persistence of dispersal-limited lichen species with narrow niches. Rapid change in microclimate due to canopy dieback exposes species to additional stressors that may limit their capacity to survive and colonize. We studied the importance of old trees as micro-refuges and microclimate stability in maintaining lichen survival and diversity. The study was situated in mountain Norway spruce (Picea abies) forests of the Gorgany Mountains of the Ukrainian Carpathian mountain belt. Lichens were collected on 13 circular study plots (1000 m2). Dendrochronological methods were used to reconstruct age structure and maximum disturbance event history. A linear mixed effects model and general additive models were used to explain patterns and variability of lichens based on stand age and disturbance history for each plot. Tree age was the strongest variable influencing lichen diversity and composition. Recent (<80 years ago) severely disturbed plots were colonized only by the most common species, however, old trees (>200 years old) that survived the disturbances served as microrefuges for the habitat-specialized and/or dispersal limited species, thus epiphytic lichen biodiversity was markedly higher on those plots in comparison to plots without any old trees. Most species were able to survive microclimatic change after disturbances, or recolonize disturbed patches from surrounding old-growth forests. We concluded that the survival of old trees after disturbances could maintain and/or recover large portions of epiphytic lichen biodiversity even in altered microclimates. Keywords: Biodiversity Colonization Forest continuity Microclimate Species refuges Tree age.

Lichen symbioses are defined as a symbiotic relationship between a mycobiont (generally an ascomycete) and one or more photobionts (green algae or/and cyanobacteria). It was proposed that cephalodia emancipation is an evolutionary driver for photobiont switch from chlorophyte to cyanobacteria. In this study we want to test the monophyly of cyanolichens and to measure the phylogenetic signal of the symbiotic relationship between cyanobacteria and a mycobiont partner in the lichen genus Pseudocyphellaria. This genus includes some species that have a chlorophyte as primary photobiont (and Nostoc in internal cephalodia), while others have only cyanobacteria. In a phylogenetic framework we measure the phylogenetic signal (or phylogenetic dispersion) as well as mapped photobiont switches performing stochastic character mapping. Results show that having cyanobacteria as main photobiont has a strong phylogenetic signal that follows a Brownian motion model. Seven clades in the phylogeny had an ancestor with cyanobacteria. Reversal to a green algae photobiont is rare. Several switches were estimated through evolutionary time suggesting that there was some flexibility in these traits along the phylogeny; however, close relatives retained cyanobacteria as main photobiont throughout the cyanolichen’s history. Photobiont switches from green algae to cyanobacteria might enhance ecotypical differentiation. These ecotypes could lead to several speciation events in the new lineage resulting in the phylogenetic signal found in this study. We give insights into the origin of lichen diversity exploring the photobiont switch in a phylogenetic context in Pseudocyphellaria s. l. as a model genus. Keywords: Evolutionary driver .

Water Soluble Bulk Deposition (WSBD) and Water Soluble Leaching (WSL) from Pseudevernia furfuracea thalli transplanted in a anthropized zone were separately collected in four locations where weather stations were set up for monitoring rainfalls rate and daily temperature. The thalli were exposed for three months during which 13 major rainfalls took place. The concentrations of 15 elements (Al, V, Cr, Mn, Co, Ni, Cu, Zn, Mo, Pb, As, Cd, Ti, Sn, Sb) were measured as well in WSBD and WSL as in the lichen thalli at the end of the exposure period. The total bioaccumulation of each element was significantly correlated with its % representation in both the lichen input (WSBD) and output (WSL). Elements with a small water-soluble input-pool were mostly taken up by the thalli (output/input < 1). Among the elements with a high input-pool, Zn was nearly systematically taken up while Al and Mn were lost (output/input > 1). Al showed a significant direct correlation with the increase in mm and hours of rainfall (i.e. transition from net loss to net uptake) while Mn showed an inverse correlation (transition from net uptake to net loss), which may be due to element competition modulated by water-stimulated lichen physiology. Al was strongly bioaccumulated while Mn showed a slight increase in exposed thalli. This suggests that rainfall-induced loss can result in an underestimation by lichen biomonitoring of element concentrations in atmospheric deposition and an increase in the bioavailability of potential toxic elements for other environmental compartments.

Conflicting evidence of the impact of forest management on biodiversity exists, either decreasing or increasing species richness. Variable diversity responses may result from the adoption of different unmanaged reference systems, ranging from stands with management abandonment in the recent past to true primeval forests. We compared the species richness of epiphytic bryophytes and lichens and vascular forest floor plants in three primeval forest/production forest pairs of Fagus sylvatica in Slovakia, adopting a replicated design and a reference system without any management legacy. Mean number of bryophyte and lichen species per 500 m2-plot tended to be higher in the primeval forests, while the mean α-diversity of vascular plants was higher in the production forests. In contrast, the β-diversity of the three plant groups as expressed by the Sørensen Dissimilarity Index was generally higher in the primeval forest plot sample, reflecting a higher heterogeneity of plant community composition and habitat diversity. Plotting cumulative species numbers against plot numbers suggests that the curves for bryophyte and lichen species richness may saturate at ca. 250 plots or ∼12.5 ha in the primeval forests, but already at 30–60 plots (<3 ha) in the more homogeneous production forests. Total bryophyte and lichen species numbers are estimated to be 30–100% larger in the primeval forests than the production forests. Contrary to general belief, vascular plant species richness was similarly high, or even higher, in the primeval forests when >50 plots (total area: 2.5 ha) were investigated, evidencing the importance of natural disturbance regimes for maintaining high forest biodiversity. Our results show that Fagus sylvatica primeval forests are inhabited by a species-rich epiphyte flora despite the species poverty of the tree layer. This evidences the outstanding value of primeval forest reserves for the conservation of temperate forest biodiversity. Keywords: biodiversity offsetting, old-growth, restoration, secondary forest.

Both active and passive forest restoration schemes are used in degraded landscapes across the world to enhance biodiversity and ecosystem service provision. Restoration is increasingly also being implemented in biodiversity offset schemes as compensation for loss of natural habitat to anthropogenic development. This has raised concerns about the value of replacing old-growth forest with plantations, motivating research on biodiversity recovery as forest stands age. Functional diversity is now advocated as a key metric for restoration success, yet it has received little analytical attention to date. We conducted a meta-analysis of 90 studies that measured differences in species richness for functional groups of fungi, lichens, and beetles between old- growth control and planted or secondary treatment forests in temperate, boreal, and Mediterranean regions. We identified functional-group–specific relationships in the response of species richness to stand age after forest disturbance. Ectomycorrhizal fungi averaged 90 years for recovery to old-growth values (between 45 years and unrecoverable at 95% prediction limits), and epiphytic lichens took 180 years to reach 90% of old-growth values (between 140 years and never for recovery to old-growth values at 95% prediction limits). Non-saproxylic beetle richness, in contrast, decreased as stand age of broadleaved forests increased. The slow recovery by some functional groups essential to ecosystem functioning makes old-growth forest an effectively irreplaceable biodiversity resource that should be exempt from biodiversity offsetting initiatives.

Arboreal lichens have a wide range of tolerance to habitat disturbance. As a result, they have been used globally as bioindicators of environmental change, particularly for monitoring atmospheric pollution. Here, we use lichens to monitor air quality and ecological integrity (EI) at Kejimkujik National Park and National Historic Site in Nova Scotia, Canada. We provide descriptions of two protocols and compare the results using data gathered in 2006, 2011, and 2016. To monitor air quality, we established 12 monitoring sites throughout the park and used a suite of lichens that are intolerant to air pollution to develop an index of air purity (IAP) that we compared every 5 years. Our protocol for monitoring EI of forest ecosystems was set up at these same 12 sites. We selected 50 regionally common field-identifiable lichen species and genera ranging in sensitivity from disturbance-tolerant to intolerant, and compare their presence in spatially constrained zones on a variety of tree species every 5 years. Our results suggest that air quality in Kejimkujik has increased slightly in the 10 years since monitoring was implemented, which is consistent with improvements in local air quality. Species richness also increased slightly, suggesting that EI has not declined. The maintenance of EI, through protection and restoration of natural resources, is a key priority in the management of national parks in Canada. Our protocols will provide early detection of changes to EI, enabling park managers to take responsive action. We are confident that our protocols can be replicated in other parts of the world with different suites of regionally common lichens. Highlights: • A regionally specific suite of lichen species was successfully selected to monitor air quality and ecological integrity. • New monitoring protocols for air quality and ecological integrity were developed and successfully implement. • A positive correlation between the abundance of pollution intolerant species and a decline in air pollution was shown. • Regional suites of lichens can be used as a management tool for early detection ofdisturbances and environmental changes.

A 2014 case study investigated the relative accumulation efficiency of polycyclic aromatic hydrocarbons (PAHs), total sulfur (S), total nitrogen (N), major and minor elements and Pb isotopes in five common lichen species at three boreal forest sites in the Athabasca Oil Sands Region (AOSR) in northeastern Alberta, Canada to identify the optimum lichen species for future biomonitoring. Differences in concentrations of PAHs, multiple elements, and Pb isotopes in fruticose (Bryoria furcellata, Cladina mitis, Evernia mesomorpha) and foliose (Hypogymnia physodes and Tuckermannopsis americana) lichens were found along a 100 km distance gradient from the primary oil sands operations. Integration of insights from emission source samples and oil sands mineralogy in consort with aerosol collection indicates incorporation of more fine particulate matter (PM) into foliose than fruticose lichen biomass. Contrasting PAH with element concentrations allowed lichen species specific accumulation patterns to be identified. The ability of lichen species to incorporate different amounts of gas phase (S and N), petrogenic (V, Ni, Mo), clay (low Si/Al and more rare earth elements), and sand (higher Si/Al and Ti) components from the oil sand operations reflects aerosol particle size and lichen physiology differences that translate into differences in PM transport distances and lichen accumulation efficiencies. Based on these findings Hypogymnia physodes is recommended for future PAH biomonitoring and source attribution studies. Highlights: Five lichen species collected from three site transect in Athabasca Oil Sands Region. Lichen specific concentration gradients in PAHs, S, N, and 32 elements were found. Different coarse and fine particulate matter multi-element fingerprints identified. Oil sands mineralogy and Pb isotopes provided particulate matter source insights. Size dependent incorporation of aerosols in foliose and fruticose lichens documented. Keywords: Oil sands; PAHs; Pb isotopes; Foliose and fruticose lichens; Major and minor elements.

The following corrections and amendments are made to the 2016 classification of lichenized fungi published in the previous issue of this journal. Four families are added: Harpidiaceae (Pezizomycotina incertae sedis), with the two genera Euopsis and Harpidium; Pleomassariaceae (Pleosporales), with the genus Splanchonema; Squamarinaceae (Lecanorales), with the two genera Herteliana (moved from Ramalinaceae) and Squamarina (moved from Stereocaulaceae); and Trichosphaeriaceae (Sordariomycetes: Trichosphaeriales), with the genus Cresporhaphis. The following previously overlooked genera are also added: Allophoron (Pezizomycotina incertae sedis), Cresporhaphis (Trichosphaeriaceae), Gabura (Arctomiaceae), Julella (Trypetheliaceae), Knightiella (Icmadophilaceae), Porpidinia (Lecideaceae), Protoroccella (Roccellaceae), Psoromidium (Pannariaceae) and Tremotylium (Arthoniales incertae sedis). The classification is adjusted for four genera: Asteroporum (moved from Pezizomycotina incertae sedis to Dothideomycetes incertae sedis), Eremastrella (moved from Psoraceae to Lecideaceae), Hosseusia (moved from Pannariaceae to Lecanoromycetes incertae sedis) and Joergensenia (moved from Lecanorales incertae sedis to Pannariaceae). Further, the following overlooked generic synonyms are listed: Buscalionia (= Marcelaria [nom. cons. prop.]), Degeliella (= Psoromaria), Dirinastrum (= Buellia), Gymnographa (= Phaeographis), Kroswia (= Fuscopannaria), Marfloraea (= Lepra), Medusulina (= Fissurina), and Phaeographina (= Pliariona); the genus Anapyrenium is discussed as a potential synonym of Thelomma. Species numbers are adjusted for nine genera: Austrella (Pannariaceae; 3 spp.), Icmadophila (Icmadophilaceae; 5 spp.), Lepidocollema (Pannariaceae; 23 spp.), Massalongia (Massalongiaceae; 6 spp.), Parmeliella (Pannariaceae; 70 spp.), Psoromidium (Pannariaceae; 1 spp.), Pyrgillus (Pyrenulaceae; 7 spp.), Siphula (Icmadophilaceae; 17 spp.) and Synarthonia (Arthoniales incertae sedis; 5 spp.). The fossil lichen Honeggeriella (complexa) is validated by adding MycoBank registration numbers, the validity of the genus name Pallidogramme (Graphidaceae) is discussed and confirmed, and the authorship of the name Thallinocarpon (Lichinaceae) is clarified. Several genera are (continued to be) considered non-lichenized, namely Chaenothecopsis (Eurotiomycetes: Mycocaliciales: Sphinctrinaceae), Limboria (newly lectotypified with L. constellata; Pezizomycotina incertae sedis), Naetrocymbe (Dothideomycetes: Pleosporales: Naetrocymbaceae), and Obryzum (Dothideomycetes incertae sedis: Obryzaceae); the status of the genus Pleurotrema (Dothideomycetes incertae sedis: Pleurotremataceae) is also discussed. Seven genera are corrected to have molecular data available: Adelolecia, Aspiciliopsis, Aspilidea, Crocodia, Parasiphula, Vezdaea and Xylopsora. With these corrections, the number of lichenized species is now tabulated at 19,409 and the number of fungal genera, families, and orders including lichens at 1,002, 119, and 40, respectively.Keywords: Delichenization, Diploschistes, lichen species richness, Mycocaliciales, Peltigerales.

We describe the new genus, Sprucidea M.Cáceres, Aptroot & Lücking, from rain forest areas in South America and Southeast Asia. Phylogenetic analysis of the mtSSU and nuLSU markers place Sprucidea within Malmideaceae, sister to the genus Savoronala from Madagascar. Like Malmidea, Sprucidea is characterized by frequently red thalli containing norsolorinic acid, but differs in the bacillar instead of ellipsoid ascospores and in the stalked sporodochia as conidiomata; from Savoronala, Sprucidea is distinguished by the crustose thallus and short stalks of the sporodochia. The new genus thus far contains four species, two of them new to science, namely S. granulosa M.Cáceres, Aptroot & Lücking and S. rubropenicillata M.Cáceres, Aptroot & Lücking (type species), and two newly proposed combinations: S. gymnopiperis (Kalb) M.Cáceres, Aptroot & Lücking (basionym: Malmidea gymnopiperis Kalb) and S. penicillata (Aptroot, M.Cáceres, Lücking & Sparrius) M.Cáceres, Aptroot & Lücking (basionym: Bacidina penicillata Aptroot, M.Cáceres, Lücking & Sparrius). In addition, we propose the new combination Malmidea floridensis (Nyl.) M.Cáceres, Aptroot & Lücking (basionym: Lecidea floridensis Nyl.). We further include the pantropical genus Crustospathula (with currently five species) in Malmideaceae, differing from the other genera by its stalked soralia. With the recent addition of the genus Kalbionora, Malmideaceae thus contains five genera and two additional, orphaned lineages of species currently included in Lecidea s.l. A key to all genera and lineages is provided, as well as a key to all species of Sprucidea and Crustospathula.

Zwackhia viridis is a crustose lichen being found in forests throughout Poland. It belongs to rare species being labelled primeval forest lichens which are associated with large forest complexes. The eastern populations of Z. viridis were examined using RAPD technique in order to check whether geographic distance affects genetic diversity of the populations under study. The analysis of seven populations of that species showed large intraspecific diversity. The greatest genetic similarity occurred between populations from the north-eastern area of the country, about 300 km away from each other. In dendrograms, only these populations have simple matching distance greater than 50%. lichens; random amplified polymorphic DNA (RAPD), genetic variation

Lichens, symbiotic associations of fungi (mycobionts) and green algae or cyanobacteria (photobionts), are poikilohydric organisms that are particularly well adapted to withstand adverse environmental conditions. Terrestrial ecosystems of the Antarctic are therefore largely dominated by lichens. The effects of global climate change are especially pronounced in the maritime Antarctic and it may be assumed that the lichen vegetation will profoundly change in the future. The genetic diversity of populations is closely correlated to their ability to adapt to changing environmental conditions and to their future evolutionary potential. In this study, we present evidence for low genetic diversity in Antarctic mycobiont and photobiont populations of the widespread lichen Cetraria aculeata. We compared between 110 and 219 DNA sequences from each of three gene loci for each symbiont. A total of 222 individuals from three Antarctic and nine antiboreal, temperate and Arctic populations were investigated. The mycobiont diversity is highest in Arctic populations, while the photobionts are most diverse in temperate regions. Photobiont diversity decreases significantly towards the Antarctic but less markedly towards the Arctic, indicating that ecological factors play a minor role in determining the diversity of Antarctic photobiont populations. Richness estimators calculated for the four geographical regions suggest that the low genetic diversity of Antarctic populations is not a sampling artefact. Cetraria aculeata appears to have diversified in the Arctic and subsequently expanded its range into the Southern Hemisphere. The reduced genetic diversity in the Antarctic is colonization

Premise of the study: Many lichens exhibit extensive ranges spanning several ecoregions. It has been hypothesized that this wide ecological amplitude is facilitated by fungal association with locally adapted photobiont strains. Methods: We studied the identity and geographic distribution of photobionts of the widely distributed North American lichen Ramalina menziesii based on rbcL (chloroplast DNA) and nuclear ribosomal ITS DNA sequences. To test for ecological spe- cialization, we associate photobiont genotypes with local climate and phorophyte. Key results: Of the photobiont lineages of R. menziesii, 94% belong to a clade including Trebouxia decolorans. The remaining are related to T. jamesii. The photobionts showed (1) significant structure according to ecoregion and phorophyte species and (2) genetic associations with phorophyte species and climate. Conclusions: Geography, climate, and ecological specialization shape genetic differentiation of lichen photobionts. One great advantage of independent dispersal of the fungus is symbiotic association with locally adapted photobiont strains. ecological specialization; genetic differentiation; host plant specificity; lichenized ascomycetes; phorophyte; photobiont; Ramalina menziesii; Ramalinaceae; symbiosis; Trebouxia decolorans; Trebouxiophyceae.

The Mediterranean region, comprising the Mediterranean Basin and the Macaronesian Islands, represents a center of diversi cation for many organisms. The genetic structure and connectivity of mainland and island microbial populations has been poorly explored, in particular in the case of symbiotic fungi. Here we investigated genetic diversity and spatial structure of the obligate outcrossing lichen-forming fungus Parmelina carporrhizans in the Mediterranean region. Using eight microsatellite and mating-type markers we showed that fungal populations are highly diverse but lack spatial structure. This is likely due to high connectivity and long distance dispersal of fungal spores. Consistent with low levels of linkage disequilibrium and lack of clonality, we detected both mating-type idiomorphs in all populations. Furthermore we showed that the Macaronesian Islands are the result of colonization from the Mediterranean Basin. The unidirectional gene ow, though, seemed not to be su cient to counterbalance the e ects of drift, resulting in comparatively allelic poor peripheral populations. Our study is the rst to shed light on the high connectivity and lack of population structure in natural populations of a strictly sexual lichen fungus. Our data further support the view of the Macaronesian Islands as the end of the colonization road for this symbiotic ascomycete

Phylogenetic and phylogeographic approaches have become widespread in evolutionary biol‐ ogy, ecology, and biogeography. However, analyses that incorporate inferences from historical biogeography (e.g., timing of colonization of a region) may be essential to answer the most important large‐ scale questions in these fields, but they remain infrequently used. I focus on two examples here. First, I argue that understanding the origins of biodiversity hotspots (and other high‐diversity regions) requires comparing the timing of biogeographic colonization and diversification rates among regions. In contrast, phylogeographic studies (e.g., analyses within species within a region) may themselves say little about why a region is diverse relative to others. Second, incorporating historical biogeograpy can help address the processes that determine community species richness and structure, such as dispersal, in‐situ trait evolution, and in‐situ speciation. In contrast, the widespread “community phylogenetics” approach (focusing on relatedness of species in communities) may have limited ability to explain community rich‐ ness and structure. biodiversity hotspot, biogeography, community ecology, community phylogenetics, phylogeny, phylogeography, species richness

Current research has dramatically increased our understanding of the geographical distribu- tion of lichens and allowed new insights in the importance of the photosynthetic partners for shaping the spatial distribution of these symbi- otic organisms. Novel methods, including the increased availability of data from environmen- tal sampling, will further enhance and refine our hypotheses to explain distribution patterns. These are truly exciting times—with the help of next-generation sequencing techniques, increased number of species for which micro- satellite markers have been identified, and improved analytical tools, biogeographical questions can be addressed that were beyond our reach only a decade ago. Improved under- standing of species delimitations of the fungal partners has allowed us to better understand distribution patterns, and in tandem with enhanced knowledge of species diversity of photosynthetic partners, this provides an ave- nue to better understand patterns that explain distribution patterns at an ecological level. Currently, ecological biogeographical studies focus on a few species that provide great insights, but we look forward to seeing these exemplary studies extended to other lichens, including phylogenetically distant groups and also tropical species, which are currently severely understudied. The extension of research to include a wider amplitude of species will also strengthen predictions of the impact of global climatic change to lichen distribution.

A new revised checklist of lichenized fungi in Thailand is presented, including 1,292 species. Recent work on the taxonomy of these organisms in Thailand resulted in an enormous increase in our knowledge of the lichen biota of the country – the current checklist includes more than twice as many species as the previous catalogue published 15 years ago – and phylogenetic studies resulted in numerous changes in the generic classification of lichenized fungi. Hence, a new checklist is here presented summarizing the current knowledge of lichens in Thailand. Six new records are reported, viz. Acanthothecis salazinica, Bactrospora metabola, Buellia parastata, Diploschistes cinereocaesius, Rolfidium coccocarpioides, and Trapelia placodioides. Five previously recorded species, namely Lecanora carpinea, Platismatia glauca, P. lacunosa, P. tuckermanii and Roccella phycopsis are shown to be based on misidentifications and are excluded from the checklist. Three new combinations of species previously placed in Pertusaria to Lepra are proposed: L. bulolensis (A.W.Archer, Elix & Streimann) Schmitt & Lumbsch, L. patellifera (A.W.Archer) Schmitt & Lumbsch, and L. subventosa (Malme) Schmitt & Lumbsch. Keywords: Asia, biodiversity, lichens, new records, taxonomy.

lichens, oristic nding, biogeography, ecology, indicator species, ecological continuity, Mordovskiy Reserve, Eastern Europe. Micarea tomentosa is reported as new to Russia from one locality in the Republic of Mordovia, where it grows on decaying wood of Alnus glutinosa in humid habitat of the old alder forest in the oodplain of the Vyaz- Pushta stream in Mordovskiy Reserve. M. tomentosa is similar to M. hedlundii stalked, whitish and tomentose pycnidia, but has a more brightly colored and more continuous thallus which is composed of granules larger than the goniocysts of M. hedlundii; anatomically, the two species can be differentiated by the presence of the dull orange pig- ment (reacting K+ violet, C+ violet) within the goniocysts of M. hedlundii; the apothecia of M. tomentosa are pale to slightly brownish, pinkish-brown usually simple and adnate while the apothecia of M. hedlundii are often tuberculate, larger and darker, pinkish-brown or brown pigmented. In addition, M. tomentosa has short (meso)condia. The spe- cies was known earlier only from four European countries (Poland, Slovakia, Estonia and Sweden), where it occurrs mostly within large complexes of natural forest ecosystems, especially in protected nature reserves, demonstrating its particular role as an indicator of ecological continuity for forest habitats. Considering the earlier known distribution of M. tomentosa, the Mordovian nding extends its known geographic range far to the East and con rms its occurrence in the Eastern Europe

Taxa in the genus Melanelia (Parmeliaceae, Ascomycota) belong to a group of saxicolous lichens with brown to black foliose thalli, which have recently undergone extensive changes in circumscription. Taxa belonging to Parmeliaceae are prolific producers of bioactive com- pounds, which have also been traditionally used for chemotaxonomic purposes. However, the chemical diversity of the genus Melanelia and the use of chemical data for species dis- crimination in this genus are largely unexplored. In addition, identification based on morpho- logical characters is challenging due to few taxonomically informative characters. Molecular identification methods, such as DNA barcoding, have rarely been applied to this genus. This study aimed to identify the Melanelia species from Iceland using DNA barcoding approach, and to explore their chemical diversity using chemical profiling. Chemometric tools were used to see if lichen metabolite profiles determined by LC-MS could be used for the identifi- cation of Icelandic Melanelia species. Barcoding using the fungal nuclear ribosomal internal transcribed spacer region (nrITS) successfully identified three Melalenlia species occurring in Iceland, together with Montanelia disjuncta (Basionym: Melanelia disjuncta). All species formed monophyletic clades in the neighbor-joining nrITS gene tree. However, high intra- specific genetic distance of M. stygia suggests the potential of unrecognized species line- ages. Principal component analysis (PCA) of metabolite data gave a holistic overview showing that M. hepatizon and M. disjuncta were distinct from the rest, without the power to separate M. agnata and M. stygia due to their chemical similarity. Orthogonal partial least– squares to latent structures–discriminate analysis (OPLS-DA), however, successfully distin- guished M. agnata and M. stygia by identifying statistically significant metabolites, which lead to class differentiation. This work has demonstrated the potential of DNA barcoding, chemical profiling and chemometrics in identification of Melanelia species

Desertification is currently a major concern, and vast regions have already been devastated in the arid zones of many countries. Combined application of cyanobacteria with soil fixing chemicals is a novel method of restoring desertified areas. Three cyanobacteria, Nostoc sp. Vaucher ex Bornet & Flahault, Phormidium sp. Ku ̈tzing ex Gomont and Scytonema arcan- geli Bornet ex Flahault were isolated and tested in this study. Tacki-SprayTM (TKS7), which consists of bio-polysaccharides and tackifiers, was used as a soil fixing agent. In addition, superabsorbent polymer (SAP) was applied to the soil as a water-holding material and nutri- ent supplement. Application of cyanobacteria with superabsorbent polymer and TKS7 (CST) remarkably improved macro-aggregate stability against water and erodibility against wind after 12 months of inoculation when compared to the control soil. The mean weight diameter and threshold friction velocity of the CST treated soil were found to be 75% and 88% of those of the approximately 20-year-old natural cyanobacterial crust (N-BSC), re- spectively, while these values were 68% and 73% of those of the N-BSC soil after a single treatment of cyanobacteria alone (CY). Interestingly, biological activities of CST were similar to those of CY. Total carbohydrate contents, cyanobacterial biomass, microbial biomass, soil respiration, carbon fixation and effective quantum yield of CST treated soil were en- hanced by 50–100% of the N-BSC, while those of control soil were negligible. Our results suggest that combined application of cyanobacteria with soil fixing chemicals can rapidly develop cyanobacterial crust formation in the field within 12 months. The physical properties and biological activities of the inoculated cyanobacterial crust were stable during the study period. The novel method presented herein serves as another approach for combating desertification in arid regions

A conspicuous yellow crust forming extensive covers on some dry and shaded limestone rocks in Europe is described here as Caloplaca substerilis subsp. orbicularis M. Haji Moniri, Vondrák & Malíček subsp. nov. Based on nuITS rDNA, 28S nuLSU rDNA and mtSSU rDNA sequence data, the new taxon is closely related to Caloplaca substerilis and C. ulcerosa. e three taxa form a supported clade in the subfamily Xanthorioideae (Teloschistaceae), but none of the recently seggregated genera are suitable for them. In the ITS phylogeny, the new taxon forms a monophylum nested within C. substerilis. However, its extensive yellow thalli and absence of vegetative diaspores clearly distinguish it from Caloplaca substerilis (subsp. substerilis). Indeed, if it had not been for the molecular evidence, we would have described it at the rank of species. We suggest that the substrate switch and accompanying processes are responsible for the striking phenotypic di erence between Caloplaca substerilis subsp. substerilis and C. substerilis subsp. orbicularis

Three species of map lichens, Rhizocarpon atroflavescens, R. carpaticum and R. ferax, have newly been discovered in the Czech Republic. These taxa occur predominantly in mountain regions with uncovered rocky outcrops and boulders. Rhizocarpon atrofla- vescens has a whitish prothallus and ascospores containing at most one longitudinal septum. It grows on slightly calcareous rocks. The acidophilous species Rhizocarpon carpaticum also rarely has one longitudinal septum; however, the species has convex apothecia extending up above the areoles and the thallus margin is bordered with a black prothallus. Rhizocarpon ferax occurs mainly on overhangs or at bases of vertical faces of acidic rocks. It has muriform spores and its roundish apothecia are usually hidden between two crescent-shaped areoles

During the course of floristic studies of Japa- nese lichens, Glyphis cicatricosa Ach. (Graphi- daceae, Ascomycota), a pantropical species (Galloway 2007), was found on the bark of Phellodendron amurense Rupr. in a suburban area of Tsukuba-city (36°06'03''N, 140° 06'43''E). This is on the Pacific side of eastern Honshu, with a warm-temperate climate and is the northernmost locality of G. cicatricosa in Japan. The sapling tree was planted in the Tsukuba Botanical Garden (c. 14 ha, 20 m elev.) in 1984 when the mean annual temperature was 12 °C, but this has gradually increased since then to almost 15 °C in 2015 when G. cicatricosa was discovered (Fig. 1). Does an increase in annual temperature at this site plausibly explain the unexpected phyto- geographical distribution of this lichen in terms of ‘global warming’, or is it the result of an ‘urban heat island’ effect, or indeed is it related to one or more other factors?

Macro-morphological features traditionally used to segregate genera in Parmeliaceae have been shown to be highly plastic, placing limits on their taxonomic value. Here we aim to elucidate the evolutionary relationships of the genera Relicina and Relicinopsis and reassess the phenotypic features traditionally used to separate these genera. To this end, we gathered ribosomal DNA sequences of ITS, nuLSU and mtSSU and analyzed them in a phylogenetic framework. Relicina was recovered as paraphyletic, with Relicinopsis nested within, and three different clades were identified within Relicina. Alternative hypothesis tests significantly rejected the monophyly of Relicina. Our results indicate that the presence or absence of bulbate cilia is of limited taxonomic value in this clade. Based on differences in conidia, however, we propose to accept Relicinopsis as a subgenus within Relicina as Relicina subgen. Relicinopsis (Elix & Verdon) Kirika, Divakar & Lumbsch. It is proposed that five new combinations of species previously classified in Relicinopsis be placed in Relicina. generic circumscription, integrative taxonomy, lichenized fungi, molecular systematics, parmelioid lichens

Phylogenetic analyses of nuclear (Mcm7, nrITS, nrLSU) and mitochondrial (mrSSU) DNA sequences revealed geographically disjunct lineages in Leptogium hibernicum. One of these lineages is described here as Leptogium krogiae, which differs from L. hibernicum in the thinner thallus (190–210 μm vs. 390–480μm), shallowly striate lobes instead of deeply furrowed lobes, isidia that are seldom distinctly flattened, and apothecia with a subhymenial euparaplectenchymatous layer. Leptogium krogiae is a widespread epiphyte in mist-affected woodlands and montane forests in East Africa and appears to be a common species.

Lichens as sessile and slow-growing symbiotic associations have evolved various carbon- based secondary compounds (CBSCs) to mitigate the effects of some stressors in the extreme environments in which they often grow. The mat-forming lichen Cladonia stellaris, an important fodder for reindeer, produces usnic acid in the outermost layer and perlatolic acid in the medulla. Here, we studied effects of simulated global warming on these CBSCs in C. stellaris cultivated in climate chambers with: 1) ambient conditions as control or 2) ambient conditions +4°C. The chambers simulated, at an hourly resolution, an averaged 10-year growing season dynamic from a long-term monitored boreal mire in northern Sweden. After two months of acclimation, +4 °C warming in one simulated growing season increased the concentration of usnic acid by 31% compared with ambient conditions, whereas the warming decreased the concentration of perlatolic acid by 14%. Since lichen CBSCs play important roles in ecosystem processes such as lichenivory and decomposition, these changes may profoundly affect lichen-dominated ecosystems. boreo-arctic ecosystems, carbon based secondary compounds, climate change, reindeer lichen

The Trebouxia photobiont freshly isolated from Xanthoria parietina (L.) Th. Fr. was used to develop a live cell chondriome (mitochondrial DNA) labelling method. In the initial phase six candidate dyes were tested and compared for mitochondrial labelling utility as assessed by the signal to noise ratio (SNR) of the mitochondrial signal to the adjacent cellular background in standardized confocal images of 30 labelled cells. DIOC7, JC-1 and MitoTracker orange (MTO) dyes showed some labelling ability. MTO had significantly higher utility than the other dyes. In a second phase, MTO concentration was optimized. The final labelling protocol was a 30 minute incubation with 1 μM of MTO. The resultant labelling was suitable for both widefield and confocal microscopy. Both 2D thresholding and 3D volume construction are demonstrated using the resultant data. The protocol can therefore be utilized for both qualitative research and for quantitative measurement of the chondriome in Trebouxia photobionts. This will facilitate a wide range of mitochondrial investigations in lichenology. chondriome, dyes, lichens, microscopy, MitoTracker orange, photobiont

Pyrgillus tibellii Kr. P. Singh & Pushpi Singh was described from Arunachal Pradesh in the Eastern Himalaya, India (Singh & Singh 2012a). In the same year Kashiwadani et al. (2012) described P. cambodiensis Kashiw. et al. from Cambodia (Fig. 1). Recently, Shi et al. (2015) reported P. cambodiensis and P. javanicus (Mont. & Bosch) Nyl. as new to China from southern Yunnan and considered P. tibellii (Fig. 2) as conspecific with Pyrgillus cambodiensis following the rule of priority (Art. 11.4; McNeill et al. 2012). Shi et al. (2015), however, ignored the chemistry of P. tibellii. We have examined the holotype of P. cambodiensis (Cambodia: Siem Reap Province, Western Prasat Top, Angkor Wats complex, Siem Reap, 13°26'N, 103°51'E, alt. c. 30 m, on bark of Dipterocarpus elatus, 24 November 2010, H. Kashiwadani 50508) borrowed from TNS Japan and found it clearly distinct from the type of P. tibellii (India: Arunachal Pradesh, Papumpare dis- trict, Sankei view, on bark, alt. c. 340m, 12 January 1997, K. P. Singh 9616) housed at ASSAM in India. Pyrgillus tibellii, although similar to P. cambodiensis in morphology and anatomy (they both have 3-septate ascos- pores), is easily distinguished from the latter by its larger ascospores and the presence of lichexanthone (UV+ yellow) in the thallus. In lichen taxonomy, secondary metabolites play a significant role in delimiting species (Hawksworth 1976; Lumbsch 1998a, b; Luangsuphabool et al. 2016). Reaction to ultraviolet (UV) has been considered an important and necessary criterion for the identification of several lichen species (Aptroot 2012). It is therefore concluded that P. tibellii and P. cambodiensis are two distinct taxa and not conspecific as treated by Shi et al. (2015). Pyrgillus tibellii is endemic to India, so far confined to Arunachal Pradesh in Eastern Himalaya and Kerala in Western Ghats, and grows on trees in tropical forests at lower elevations. It might possibly also occur in China. The genus Pyrgillus Nyl. belongs to the family Pyrenulaceae and is so far represented by seven species (Aptroot 1991; Kashiwadani et al. 2012; Singh & Singh 2012b), four of which occur in India (Singh & Singh 2012b). We present a key to these species.

The lowland area of southern Vietnam contains a high diversity of corticolous, crustose lichens, particularly in the family Graphidaceae. Two species, Acanthothecis verrucosa S. Joshi, Upreti & Hur and Graphis exuta S. Joshi, Upreti & Hur, are described new to science. Acanthothecis verrucosa is characterized by a verrucose, olive green thallus containing irregular to shortly lirellate apothecia, hyaline to brownish proper exciple apically lined by robust periphysoids, muriform ascospores, 30–70 × 15–20 μm, and the presence of psoromic and subpsoromic acids. Graphis exuta is characterized by a smooth, greenish white thallus, simple lirellae lacking thalline margin, entire labia coarsely white pruinose towards slit, muriform ascospores, 20–35 × 10–13 μm, and norstictic acid in the thallus. A new name, Acanthothecis yokdonensis S. Joshi & Hur, is proposed here for the species Acanthothecis salazinica S. Joshi & Hur, a later homonym of A. salazinica van den Boom & Sipman. In addition, 34 species from Vietnam are newly reported. A world key to the group of Graphis species characterized by short, simple and sessile lirellae lacking or with basal thalline margins (nuda-morph) is presented. lichen, keys, mangrove, nomenclature, taxonomy, tropical

Nitrateuptake andnitrogeninclusion into aminoacids were studied in the intact thallus and isolated bionts of the lichen Parmelia sulcata with the aid of mass spectroscopic tracing of heavy isotope 15N. The isolated photobiont, the green algae Trebouxia sp. did not take up nitrate, whereas the mycobiont and intact thalli were enriched in 15N when incubated with Na15NO3. Pulse feeding experiments with intact thalli followed by separation of photobiont showed that the labelled nitrate was originally assimilated by the mycobiont and only after that was detected in the photobiont. The isolated mycobiont after pulse labeling excreted labeled compounds into the incubation medium. Amino acidswere detected in the exudate. The quantities of two amino acids considerably exceeded those of the others. One wasidentifiedasalanine, theothercouldnotyetbeidentifiedwith certainty. Both of these high-quantity compounds were also much more enriched in 15N than the others. These two compounds are proposed to be the transport forms of nitrogen within the Parmelia sulcata thallus.

Accurate species delimitations are of great importance for effectively characterizing biological diversity. Our criteria for delimiting species have changed dramatically over the last decades with the increasing availability of molecular data and improvement of analytical methods to evaluate these data. Whereas reciprocal monophyly is often seen as an indicator for the presence of distinct lineages, recently diverged species often fail to form monophyletic groups. At the same time, cryptic species have repeatedly been detected in numerous organismal groups. In this study, we addressed the species delimitation in the crustose lichen-forming fungal genus Diploschistes using multilocus sequence data from specimens representing 16 currently accepted species. Our results indicate the presence of previously undetected, cryptic specieslevel lineages in the subgenus Limborina. In the subgenus Limborina, samples from different continents currently classified under the same species were shown to be only distantly related. At the same time, in parts of subgen. Diploschistes characterized by short branches, none of the currently accepted species formed monophyletic groups. In spite of the lack of monophyly in phylogenetic reconstructions, a multispecies coalescent method provided support for eight of the nine accepted species in subgen. Diploschistes as distinct lineages. We propose to reduce D. neutrophilus to synonymy with D. diacapsis and point out that additional sampling will be necessary before accepting additional species in subgen. Limborina. Keywords: BPP .

Cyclohymenia epilithica is a newly described genus and species from Oregon and Washington, U.S.A. It occurs on noncalcareous rock in the oceanic forests west of the crest of the Cascade Range. Unlike most other North American species in the Lecideaceae, it is restricted to shady habitats in cool, wet, temperate climates. It is distinguished from other members of the family by its thick, pale gray green, epilithic thallus; immersed apothecia that superficially appear like perithecia or pycnidia; and ascocarps that usually contain a central sterile column surrounded by a ring-shaped hymenium. The structure and position of the ascocarp appear to be unique among Lecideaceae and related families. The species is also unusual in producing short-lived asci; most collections have barren apothecia. Lecidea atrobrunnea subsp. deplanaica is raised to the species level. The taxon deserves specific rank, not just from its distinctive chemistry, but also from morphology, distribution, and ecology that differ from L. atrobrunnea s.str. The newly described Lecidea uniformis from Oregon and Washington, mainly west of the Cascade crest, is similar in many ways to L. fuscoatra, but the areoles are uniformly brown and do not have a differentiated gray, blackish, or whitish edge. DNA sequence data support the taxa Cyclohymenia epilithica and L. uniformis. Keywords: Ascomycota, Lecanoromycetidae, Lecideales, lichenized fungi, Pacific Northwest.

Plant abundance and distribution patterns have mostly been explained in terms of air temperatures, yet a great deal of vascular plant biomass is located below ground. Winter soil temperatures, which are related to both air temperature and snow cover, may therefore be important determinants of species composition in alpine areas. Epigeic lichens, however, have no underground biomass, and they often dominate at sites that are inhospitable to vascular plants, such as those that experience sustained periods of sub-freezing temperatures. In this study, effects of several warm- and cold-season soil-temperature variables on individual plant and lichen species common to oligotrophic alpine heaths was investigated using linear regression and ordination. The differences in growing season length as measured by soil temperatures were compared. Warm season variables were found to have less influence than cold season variables on individual species abundances in these areas. Changes in winter snow cover depth and duration, such as those that are predicted in Norway, can result in changes to soil temperature patterns, to the possible benefit of some species and detriment of others.

One specimen of an inconspicuous, corticolous lichen found on the bark of an oak tree at Buskett was identified as Pyrenula chlorospila Arnold. This species is not included in the checklist published by Sommier and Caruana Gatto in Flora Melitensis Nova (Sommier & Caruana Gatto, 1915). Instead Pyrenula nitida var nitidella is mentioned which name is also used for specimens in Caruana Gatto's collection housed in the herbarium at Argotti. Three of these specimens were also examined and were found to represent P. chlorospila. Consequently, Pyrenula chlorospila is recorded for the first time from the Maltese Islands.

The marine crustose lichen Pyrenocollema halodytes (Nyl.) R. Harris is known to grow on substrates such as limestone, chalk, molluscan shells and barnacles and is consequently considered as a marine lichen. It was formerly placed under the genus Arthopyrenia but together with other lichens from this genus all containing cyanobacteria as the symbiont photobiont was placed under the genus Pyrenocoliema. In this review Pyrenocollema halodytes is being recorded for the first time from the Maltese Islands having been found growing at Mistra Bay on the calcareous plates of the Star Barnacle Chthamalus stellatus found on rocks of the upper mediolittoral zone.

Korea is situated on the east Asian Continent and its northeast/southest extension is about 1,100 km. Phytogeographically it belongs to the easternmost part of the Sino-Himalayan Region. Korean lichens were initially studied by European and Japanese botanists and lichenologists. The first study of Korean lichens was made in 1891 by Müller J, a German lichenologist, who reported Synechoblastus bicaudatus Müll. Arg. [= Collema japonicum (Müll.Arg.) Hue]. In 1905, Hue, a French lichenologist, reported Lecanora oreina Ach. on the basis of a collection made by U. Faurie, a catholic priest and then Korean and foreign botanists or lichenologists reported Korean lichens. In 1996, Ministry of Environment reported 498 lichens species. In 2013, the newly compiled national inventory of Korean lichens, 788 taxa were recorded. Korean species of the genus Myelochroa are revised taxonomically and the following 8 species are recognized: M. aurulenta (Tuck.) Elix & Hale, M. entotheiochroa (Hue) Elix & Hale, M. galbina (Ach.) Elix & Hale, M. hayachinensis (Kurok.) Elix & Hale, M. rrugans (Nyl.) Elix & Hale, M. leucotyliza (Nyl.) Elix & Hale, M. metarevoluta (Asahina) Elix & Hale and M. perisidians (Nyl.) Elix & Hale. M. ibukiensis Moon et al. is reduced to a synonym for M. aurulenta. M. indica (Hale) Elix & Hale and M. xantholepis (Mont. & Bosch) Elix & Hale are excluded from the lichen of Korea. The propose of this survey is found out the new to Korea or new to science species. According to this study, two species, Gyalecta sp. and Hymenelia sp. are reported as new to science. 28 species were reported as new to Korea. Among them, 11 species was recorded as new to Asia;Catillaria atomarioides, Circinaria leprosescens, Eopyrenula leucoplaca, Fellhanera subtilis, Fellhaneropsis myrtillicola, Fuscidea austera, F. intercincta, Hymenelia ceracea, Psilolechia clavulifera, Strigula brevis, and Verrucaria simplex, and 2 species, Roccellina nipponica, Schismatomma ocellulatum, were reported as the second report from the world. 38 species were reported as second recoered from the Korea

There is little available information on lichen diversity and air quality in forests in South Korea. To address this, the present study aims to correlate corticolous lichen diversity with air quality in selected forests in South Korea. Two sites located on Jeju Island and one site located at Mt. Hambaek, Kangwon Province were selected for this study. Twenty trees representing two species (Quercus sp. and Pinus japonica) were chosen at each site. The coverage and frequency of corticolous lichens found on the selected trees were recorded by using 2500 cm2 grids. Ambient SO2, NO2, and O3 levels at each site were determined using OgawaTM passive samplers having filter pads coated with absorbing reagents. Lichen diversity data collected on selected trees were used to formulate the index of atmospheric purity (IAP). A total of 65 lichen species were found. A negative correlation was observed between lichen diversity expressed as IAP and the concentrations of SO2, NO2, and O3 levels. The results revealed that corticolous lichens could be used as indicators to monitor the air quality of forests in South Korea on a large scale. air pollution; bioindicator; index of atmospheric purity (IAP); forest health; lichen diversity

The seashore zonation found by Fletcher (1973) and Lewis (1964), was also found in the Faroe Islands. Following indicators are usable: Xeric supralittoral zone: Anaptychia fusca; Submesic supralittoral zone: Xanthoria parietina; Mesic supralittoral zone: Caloplaca marina and Lichina confinis; Littoral fringe: Verrucaria maura; Eulittoral Zone: Verrucaria mucosa. As the seashore is strongly influenced by guano, the lichen communities are dominated by ornitocoprophilous lichens, while the ornitocoprophobic species were not found. Almborn (1955), Søchting & Gjeldstrup (1985) and other Scandinavian lichenologists treat the m.s.l. and s.s.l. zone as one zone, but as Xanthoria parietina together with other foliose lichens invades here, it is on the basis of these foliose lichens that we divide the supralittorale zone of the Faroe Islands in a mesic supralittoral zone and a submesic supralittoral zone.

This paper presents the first quantitative vegetation analysis carried out along a continuous altitudinal gradient in the Faroe Islands. In order to describe the distribution of plant communities along altitudinal gradients, five mountains were studied. The aim was to define vegetation zones and to determine the transition boundary between temperate and arctic- alpine vegetation. The vegetation was classified into 12 plant communities belonging to four main vegetation types. Several terricolous species of macrolichens (Cladonia spp. div., Cetraria islandica, Peltigera canina, Solorina crocea) included.

Fragmentation rates in 21 populations of three foliose lichens Xanthoparmelia conspersa, Melanelixia fuliginosa ssp. fuliginosa and Parmelia saxatilis and the crustose lichen Rhizocarpon geographicum were estimated in north Wales, UK from the size frequency distribution of thalli with fragmenting centres. The Kaplan-Meier estimator suggested significant differences in fragmentation rates among populations of three of the four species. In M. fuliginosa ssp. fuliginosa, Cox regression analysis also suggested higher rates of fragmentation on rock surfaces with a greater percent lichen cover and increased diversity (Shannon-Weaver diversity index). Slope angle, aspect, texture, and location of population relative to the sea also influenced fragmentation rates. The data suggest considerable variation in fragmentation rates among populations within the same area which may be determined primarily by the intensity of competition on a rock surface.

The fossil record of lichens is scarce and many putative fossil lichens do not show an actual physiological relationship between mycobionts and photobionts or a typical habit, and are therefore disputed. Amber has preserved a huge variety of organisms in microscopic fidelity, and so the study of amber fossils is promising for elucidating the fossil history of lichens. However, so far it has not been tested as to how amber inclusions of lichens are preserved regarding their internal characters, ultrastructure, and chemofossils. Here, we apply light microscopy, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and Raman spectroscopy to an amber-preserved Eocene lichen in order to gain information about the preservation of the fossil. The lichen thallus displays lifelike tissue preservation including the upper and lower cortex, medulla, photobiont layer, apothecia, and soredia. SEM analysis revealed globular photobiont cells in contact with the fungal hyphae, as well as impressions of possible former crystals of lichen compounds. EDX analysis permitted the differentiation between halite and pyrite crystals inside the lichen which were likely formed during the later diagenesis of the amber piece. Raman spectroscopy revealed the preservation of organic compounds and a difference between the composition of the cortex and the medulla of the fossil.

Atmospheric nitrogen (N) deposition has had detrimental effects on species composition in a range of sensitive habitats, although N deposition can also increase agricultural productivity and carbon storage, and favours a few species considered of importance for conservation. Conservation targets are multiple, and increasingly incorporate services derived from nature as well as concepts of intrinsic value. Priorities vary. How then should changes in a set of species caused by drivers such as N deposition be assessed? We used a novel combination of qualitative semi-structured interviews and quantitative ranking to elucidate the views of conservation professionals specialising in grasslands, heathlands and mires. Although conservation management goals are varied, terrestrial habitat quality is mainly assessed by these specialists on the basis of plant species, since these are readily observed. The presence and abundance of plant species that are scarce, or have important functional roles, emerged as important criteria for judging overall habitat quality. However, species defined as ‘positive indicator-species’ (not particularly scarce, but distinctive for the habitat) were considered particularly important. Scarce species are by definition not always found, and the presence of functionally important species is not a sufficient indicator of site quality. Habitat quality as assessed by the key informants was rank-correlated with the number of positive indicator-species present at a site for seven of the nine habitat classes assessed. Other metrics such as species-richness or a metric of scarcity were inconsistently or not correlated with the specialists’ assessments. We recommend that metrics of habitat quality used to assess N pollution impacts are based on the occurrence of, or habitat-suitability for, distinctive species. Metrics of this type are likely to be widely applicable for assessing habitat change in response to different drivers. The novel combined qualitative and quantitative approach taken to elucidate the priorities of conservation professionals could be usefully applied in other contexts.

. - PLoS ONE, 11(9): e0163287 [17 p.].|
The historical and cultural heritage of Qingxing palace and Lingyin and Kaihua temple, located in Hangzhou of China, include a large number of exquisite Buddhist statues and ancient stone sculptures which date back to the Northern Song (960–1219 A.D.) and Qing dynasties (1636–1912 A.D.) and are considered to be some of the best examples of ancient stone sculpting techniques. They were added to the World Heritage List in 2011 because of their unique craftsmanship and importance to the study of ancient Chinese Buddhist culture. However, biodeterioration of the surface of the ancient Buddhist statues and white marble pillars not only severely impairs their aesthetic value but also alters their material structure and thermo-hygric properties. In this study, high-throughput sequencing was utilized to identify the microbial communities colonizing the stone monuments. The diversity and distribution of the microbial communities in six samples collected from three different environmental conditions with signs of deterioration were analyzed by means of bioinformatics software and diversity indices. In addition, the impact of environmental factors, including temperature, light intensity, air humidity, and the concentration of NO2 and SO2, on the microbial communities’ diversity and distribution was evaluated. The results indicate that the presence of predominantly phototrophic microorganisms was correlated with light and humidity, while nitrifying bacteria and Thiobacillus were associated with NO2 and SO2 from air pollution.

Umbilicaria esculenta has been used as a tonic food in China for several centuries owing to its pleasant flavor and health benefits. In this study, a water soluble polysaccharide, which we designated as UP2, with an average molecular weight of 3.33 × 105 Da, was isolated from U. esculenta cultivated in the Huangshan Mountain, by consecutive hot water extraction and anion-exchange chromatography. Gas chromatography analysis indicated that UP2 contained three kinds of monosaccharides, including mannose, glucose, and galactose at a molar ratio of 1.7:1.0:1.2. Linkage analysis of UP2 revealed the presence of (1 → 6)-linked glucosyl, (1 → 3,6)-linked glucosyl, t-linked galactosyl, (1 → 6)-linked galactosyl and (1 → 6)-linked mannosyl at a molar ratio of 0.7:4.6:4.1:2.2:9.1. Structural analysis determined that UP2 possessed a backbone consisting of (1 → 6)-linked β-D-glucopyranosyl and (1 → 6)-linked α-D-mannopyranosyl residues, which substituted at the O-3 position of (1 → 6)-linked β-D-glucopyranosyl residues by branches of (1 → 6)-linked α-D-galactopyranosyl and 1-linked β-D-galactopyranosyl residues. Immunostimulatory activity analysis showed that UP2 could stimulate the proliferation of RAW264.7 cells in a dose-dependent manner, and all the samples (20–500 μg/mL) were found to enhance nitric oxide production. The highest phagocytic activity of UP2 was observed at 200 μg/mL. Thus, UP2 may be a potential source of biological and pharmacological agents.

As an important successional stage and main type of biological soil crusts (BSCs) in Shapotou region of China (southeastern edge of Tengger Desert), lichen soil crusts (LSCs) often suffer from many stresses, such as desiccation and excess light intensity. In this study, the chlorophyll fluorescence and CO2 exchange in the rehydrated LSCs were detected under a series of photosynthetically active radiation (PAR) gradients to study the photosynthetic acclimation of LSCs. The results showed that although desiccation leaded to the loss of photosynthetic activity in LSCs, the fluorescence parameters including Fo, Fv and Fv/Fm of LSCs could be well recovered after rehydration. After the recovery of photosynthetic activity, the effective photosynthetic efficiency ΦPSII detected by Imaging PAM had declined to nearly 0 within both the lichen thallus upper and lower layers when the PAR increased to 200 μE m-2 s-1, however the net photosynthesis detected by the CO2 gas analyzer in the LSCs still appeared when the PAR increased to 1000 μE m-2 s-1. Our results indicate that LSCs acclimating to high PAR, on the one hand is ascribed to the special structure in crust lichens, making the incident light into the lichen thallus be weakened; on the other hand the massive accumulation of photosynthetic pigments in LSCs also provides a protective barrier for the photosynthetic organisms against radiation damage. Furthermore, the excessive light energy absorbed by crust lichens is also possibly dissipated by the increasing non-photochemical quenching, therefore to some extent providing some protection for LSCs.

Lichens form a critical portion of barren ground caribou (Rangifer tarandus groenlandicus) diets, especially during winter months. Here, we assess lichen mat volume across five herd ranges in the Northwest Territories and Nunavut, Canada, using newly developed composite Landsat imagery. The lichen volume estimator (LVE) was adapted for use across 700 000 km2 of barren ground caribou habitat annually from 1984–2012. We subsequently assessed how LVE changed temporally throughout the time series for each pixel using Theil-Sen’s slopes, and spatially by assessing whether slope values were centered in local clusters of similar values. Additionally, we assessed how LVE estimates resulted in changes in barren ground caribou movement rates using an extensive telemetry data set from 2006–2011. The Ahiak/Beverly herd had the largest overall increase in LVE (median = 0.033), while the more western herds had the least (median slopes below zero in all cases). LVE slope pixels were arranged in significant clusters across the study area, with the Cape Bathurst, Bathurst, and Bluenose East herds having the most significant clusters of negative slopes (more than 20% of vegetated land in each case). The Ahiak/Beverly and Bluenose West had the most significant positive clusters (16.3% and 18.5% of vegetated land respectively). Barren ground caribou displayed complex reactions to changing lichen conditions depending on season; the majority of detected associations with movement data agreed with current understanding of barren ground caribou foraging behavior (the exception was an increase in movement velocity at high lichen volume estimates in Fall). The temporal assessment of LVE identified areas where shifts in ecological conditions may have resulted in changing lichen mat conditions, while assessing the slope estimates for clustering identified zones beyond the pixel scale where forage conditions may be changing. Lichen volume estimates associated with barren ground caribou movement metrics in an expected manner and, as such, show value for future habitat assessments.

The current literature reveals that the intrathalline coexistence of multiple microalgal taxa in lichens is more common than previously thought, and additional complexity is supported by the coexistence of bacteria and basidiomycete yeasts in lichen thalli. This replaces the old paradigm that lichen symbiosis occurs between a fungus and a single photobiont. The lichen Ramalina farinacea has proven to be a suitable model to study the multiplicity of microalgae in lichen thalli due to the constant coexistence of Trebouxia sp. TR9 and T. jamesii in longdistance populations. To date, studies involving phycobiont diversity within entire thalli are based on Sanger sequencing, but this method seems to underestimate the diversity. Here, we aim to analyze both the microalgal diversity and its community structure in a single thallus of the lichen R. farinacea by applying a 454 pyrosequencing approach coupled with a careful ad hoc-performed protocol for lichen sample processing prior to DNA extraction. To ascertain the reliability of the pyrosequencing results and the applied bioinformatics pipeline results, the thalli were divided into three sections (apical, middle and basal zones), and a mock community sample was used. The developed methodology allowed 40448 filtered algal reads to be obtained from a single lichen thallus, which encompassed 31 OTUs representative of different microalgae genera. In addition to corroborating the coexistence of the two Trebouxia sp. TR9 and T. jamesii taxa in the same thallus, this study showed a much higher microalgal diversity associated with the lichen. Along the thallus ramifications, we also detected variations in phycobiont distribution that might correlate with different microenvironmental conditions. These results highlight R. farinacea as a suitable material for studying microalgal diversity and further strengthen the concept of lichens as multispecies microecosystems. Future analyses will be relevant to ecophysiological and evolutionary studies to understand the roles of the multiple photobionts in lichen symbioses.

A new species and genus, Kalbionora palaeotropica, is described for a crustose lichen occurring in coastal forests in Thailand, Vietnam, and northeastern Australia. It is morphologically similar to Malmidea and Eugeniella, but differing in morphological and chemical characters. The single known species in the new genus contains atranorin, zeorin, the stictic acid chemosyndrome and chlorinated xanthones. Morphologically it is characterized by having asci of the Catillaria-type, a yellowish brown colour, a granulose epihymenium, dark brown hypothecium, hyaline, 1–3 transversely septate ascospores. Molecular data strongly support a phylogenetic position in Malmideaceae, sister to a clade including Malmidea, Savoronala and two species currently placed in Lecidea s. lat.

Rock climbing has increased in popularity over the past 20 years. Meanwhile, there have been increasing calls for restrictions on rock climbing due to concerns about the impact of climbing on cliff biodiversity. However, the biological impacts of rock climbing are still not well understood. Here, I review the existing literature to assess the impact of rock climbing on cliff biodiversity. The majority of published results may be confounded by systematic abiotic differences between climbed and unclimbed cliffs, and this lack of proper controls may lead to the overestimation of the negative effects of rock climbing on biodiversity. Evidence for the impact of rock climbing on biodiversity is inconclusive for most taxa. Studies on lichens and vascular plants have described evidence for negative, positive and no effects of rock climbing. Snail biodiversity was found to be negatively affected, while reliable evidence of the impacts of rock climbing on birds is still lacking. Bryophytes were generally unaffected by rock climbing. Further research is urgently needed, because the mixed results of the existing studies do not allow final conclusions how rock climbing affects the cliff biota. Future studies should select comparable controls for biodiversity comparison, widen the focus to further cliff-associated taxa, and investigate how climbing effects vary with climbing intensity. Such studies would facilitate the improved management of rock climbing areas that are rich in biodiversity and contain rare and threatened species.

(2017): Lichen colonization and associated deterioration processes in Pasargadae, UNESCO world heritage site, Iran. - International Biodeterioration and Biodegradation, 117: 171–182.|
Knowledge on lichen and microbial colonization as well as associated biodeterioration processes of the stone cultural heritage is needed to establish proper conservation programs, but is still poor for stonework in semi-arid regions. In this study, lichen diversity was characterized on seven monumental buildings of the Pasargadae UNESCO-world heritage site (Iran). The risk of biodeterioration processes associated to lichen occurrence on two types of limestones, and the lichen resilience to mechanical cleaning intervention were examined. Physico-chemical substrate features and climatic conditions, combined with the agricultural surrounding and tourist disturbance, supported a pervasive colonization by species-poor epi- and endolithic communities, and fast recolonization processes by nitrophytic species after mechanical removal. The endolithic growth of some lichens and the penetration of hyphal structures of epilithic ones, examined by light and electron microscopy, were associated to stone disintegration and dissolution at the lichen-rock interface. Endolithic cyanobacteria were detected under lichen thalli, likely contributing to deterioration processes. Colonization and deterioration patterns did not appear peculiar with respect to previous investigations on similar communities in different climatic regions, and were mostly related to the different examined lithologies, indicating lichens as harmful biodeteriogens of the sedimentary rock materials used in the stone cultural heritage of semi-arid regions.

Endolichenic fungi are microbes that inhabit healthy inner lichen tissues without any disease symptoms. They have been reported to produce new and interesting bioactive metabolites. In the present study, an endolichenic fungus frequently isolated from surface-sterilized lichen thallus of Parmelia caperata has been described. The fungus was identified as Aspergillus tubingensis based on morphological traits and ITS rDNA sequence. Crude metabolites extracted from the culture broth exhibited considerable antimicrobial activity against a panel of clinically significant human pathogens. The fungus showed optimum antimicrobial activity in PDB medium in day 7 of incubation period. PDB medium amended with 1 % NaCl and at alkaline pH was found to be optimal for antimicrobial metabolites production. Enhanced activity was observed when the fungus was exposed briefly to a heat shock of 60 C during incubation. The metabolites showed optimum k-max at 214 nm with an absorbance value of 1.589. Molecular characterization of the isolate was carried out by ITS phylogeny and ITS2 secondary structure analyses. The phylogenetic trees based on both ITS rDNA and ITS2 sequences showed the isolate within the clade A. tubingensis. Considering the ubiquity and ambiguity in identifying Aspergillus species of different lifestyles, a method to differentiate pathogenic and endophytic Aspergillus at species level was developed using ITS2 secondary structure analysis. The results showed common folding pattern in the secondary structures with a helix and a 50 dangling end found to be highly conserved. Certain features in the secondary structure like multi-bulges and a symmetric interior loop were observed to be unique which distinguish our isolate from other A. tubingensis. Keywords: Endolichenic fungi; Parmelia caperata; Aspergillus tubingensis; Antimicrobial aktivity; ITS2 secondary structure.

Highlights: • Five montagnetol derivatives were isolated from the fertile form of Roccella montagnei collected in Vietnam. • Chemical structures were elucidated by 1D and 2D NMR, HR-ESI-MS analysis and the application of a modified Mosher method. • The cytotoxic activities of some isolated compounds against HepG2, NCI-H460, MCF-7, and HeLa cell lines were evaluated. Chemical investigation of the methanol extract of the fertile form of Roccella montagnei collected in Vietnam afforded twelve secondary metabolites, including five new montagnetol derivatives, orsellinylmontagnetols A−D and a furanyl derivative together with seven known compounds. Their chemical structures were elucidated by analysis of 1D and 2D NMR and high resolution mass spectroscopic data. The relative stereochemistry of two chiral centers (C-2 and C-3) of orsellinylmontagnetols A and B was elucidated by comparison of their coupling constants and the specific rotation with those reported in the literature while the absolute stereochemistry was determined by the application of a modified Mosher method for the hydroxy group at C-3. The absolute configuration (2R,3S) of the butanetetraol moiety of these compounds is in accordance with that of erythrin, a recognized chemotaxonomic marker of the genus Roccella. Five of these compounds were evaluated for their cytotoxic activities against four cancer cell lines. Only orsellinylmontagnetol A exerted a moderate activity against MCF-7 cell line with an IC50 value of 68.39 ± 3.46 μM.

Lichens are a source of unique secondary metabolites, which have been proved to have many biological properties with possible pharmaceutical roles, including e.g. antioxidant, antimicrobial, antifungal or anti-inflammatory activities and to be worth of consideration for potential human use. However, lichens lack cuticolar tissues and are exposed to several atmospheric contaminants, including trace elements. This work aims at exploring the potential toxicity of herbal preparations derived by the lichen Cetraria islandica due to trace element contamination, testing whether different concentrations may be observed, depending on the origin of the raw material. Fourteen samples of C. islandica, as cut dried thalli occurring on the European market, have been bought from different providers. For each sample, the concentrations of As, Cd, Co, Cu, Fe, Mn, Ni, P, Pb, V and Zn were measured on comminuted herbal substance and on the corresponding decoction, using atomic emission spectrometry (ICP-OES). The elemental concentrations in decoctions were significantly lower than those measured in raw materials, dropping down to levels of negligible health concern. Differences observed in raw materials were not observed anymore in the corresponding decoctions. Also, the elemental transfer rate from dried lichen to decoction was extremely element-specific, ranging from 2% for Cu to 95% for Zn. Keywords: Decoction; Iceland moss; Metals; Phytotherapy.

Forest canopies are heterogeneous environments where changes in microclimate over short distances create an opportunity for niche-based filtering of canopy-dwelling species assemblages. This environmental filtering may not occur if species’ physiological capacities are flexible or if rapid dispersal alleviates compositional differences. I assess the role of humidity, light and temperature gradients in structuring epiphyte communities in temperate deciduous oak (Quercus) canopies and determine whether gradients filter species with fixed traits or whether environmental constraints act primarily to alter individual phenotypes. I measured environmental conditions and seven functional traits related to water and light acquisition on individual macrolichens at 60 sample locations in northern red oaks Quercus rubra in two Piedmont forests in North Carolina, USA. The effects of environmental variables on individual-level traits and community composition were evaluated using linear mixed models and constrained ordination (RDA). In general, traits and community composition responded weakly to environmental variables and trait variation within taxa was high. Cortex thickness exhibited the strongest response, such that individuals with thicker cortices were found in samples experiencing lower humidity and higher light levels. Overall, gradients of humidity, light and temperature were not strong environmental filters that caused large changes in community composition. This was probably due to phenotypic variability within taxa that enabled species to persist across the full range of environmental conditions measured. Thus, humidity affected the phenotype of individuals, but did not limit species distributions or alter community composition at the scale of branches within trees. Community and trait responses were primarily associated with site-level differences in humidity, suggesting that in these forests landscape-scale climatic gradients may be stronger drivers of epiphyte community assembly than intra-canopy environmental gradients.

Thamnolia is a lichenized fungus with an extremely wide distribution, being encountered in arctic and alpine environments in most continents. In this study, we used molecular markers to investigate the population structure of the fungal symbiont and the associated photosynthetic partner of Thamnolia. By analyzing molecular, morphological, and chemical variation among 253 specimens covering the species distribution range, we revealed the existence of three mycobiont lineages. One lineage (Lineage A) is confined to the tundra region of Siberia and the Aleutian Islands, a second (Lineage B) is found in the high alpine region of the Alps and the Carpathians Mountains, and a third (Lineage C) has a worldwide distribution and covers both the aforementioned ecosystems. Molecular dating analysis indicated that the split of the three lineages is older than the last glacial maximum, but the distribution ranges and the population genetic analyses suggest an influence of last glacial period on the present-day population structure of each lineage. We found a very low diversity of Lineage B, but a higher and similar one in Lineages A and C. Demographic analyses suggested that Lineage C has its origin in the Northern Hemisphere, possibly Scandinavia, and that it has passed through a bottleneck followed by a recent population expansion. While all three lineages reproduce clonally, recombination tests suggest rare or past recombination in both Lineages A and C. Moreover, our data showed that Lineage C has a comparatively low photobiont specificity, being found associated with four widespread Trebouxia lineages (three of them also shared with other lichens), while Lineages A and B exclusively harbor T. simplex s. lat. Finally, we did not find support for the recognition of taxa in Thamnolia based on either morphological or chemical characters. Keywords: chemical variation; clonality; lichens; phylogeography; symbiosis; Thamnolia.

Knowledge of bacterial community host-speciﬁcity has increased greatly in recent years. However, the intermicrobiome relationships of unrelated but spatially close organisms remain little understood. Trunks of trees covered by epiphytes represent complex habitats with a mosaic of ecological niches. In this context, we investigated the structure, diversity and interactions of microbiota associated with lichens, mosses and the bare tree bark. Comparative analysis revealed signiﬁcant differences in the habitat-associated community structures. Corresponding co-occurrence analysis indi- cated that the lichen microbial network is less complex and less densely intercon- nected than the moss- and bark-associated networks. Several potential generalists and specialists were identiﬁed for the selected habitats. Generalists belonged mainly to Proteobacteria, with Sphingomonas as the most abundant genus. The generalists com- prise microorganisms with generally beneﬁcial features, such as nitrogen ﬁxation or other supporting functions, according to a metagenomic analysis. We argue that beneﬁ- cial strains shared among hosts contribute to ecological stability of the host bio- coenoses.

Aim: To assess the spatial-temporal dynamics of primary succession following deglaciation in soil-dwelling lichen communities.Location: European Alps (Austria, Switzerland and Italy). Methods: Five glacier forelands subjected to relevant glacier retreat during the last century were investigated. In each glacier foreland, three successional stages were selected at increasing distance from the glacier, corresponding to a gradient of time since deglaciation between 25 and 160 years. In each successional stage, soil-dwelling lichens were surveyed within five 1 × 1 m plots. In addition to a classical ecological framework, based on species richness and composition, we applied a functional approach to better elucidate community assembly mechanisms. Results: A positive relationship was found between species richness and time since deglaciation indicating that richer lichen communities can be found at increasing terrain ageing. This pattern was associated with compositional shifts, suggesting that different community assemblages can be found along the successional stages. The analysis of β-diversity revealed a significant nested pattern of species assemblages along the gradient (i.e. earlier successional stages hosted a subset of the species already established in older successional stages), while the turnover component was less relevant. Considering functional groups, we found contrasting patterns in relation to time since deglaciation: the incidence of species with a cyanobacterial photobiont and those reproducing by spores decreased, while that of species reproducing by vegetative propagules increased. Main conclusions: This study reveals that community assembly patterns of soil-dwelling lichens in alpine glacier forelands are ruled by mechanisms of directional species accumulation and trait selection that involve a trade-off between different functional strategies. Functional traits that reflect the dispersal and adaptation capability of the species underpin the colonization success of soil-dwelling lichens in glacier forelands. Keywords: dispersal traits, glacier forelands, photobiont type, primary succession, spatialtemporal patterns, species accumulation, species richness and composition, trait selection, β-diversity.

Aims: We hypothesize that the community response to disturbances can be interpreted as a large-scale dynamic equilibrium between multiple alternate states stemming from different species pools within a regional meta-pool and being limited by species’ multi-dimensional niches. We explore this hypothesis by examining the re-assembly of an acidophilous lichen community in response to long-term alkaline dust pollution, assuming understorey as a potential side- factor. Location: Around a cement factory in Kunda, Estonia. Methods: Lichen communities on Scots pine (Pinus sylvestris) trunks in 40 stands around a cement factory and in nine distant limestone habitats were assessed. Results: The formed bark pH gradient from pH 2.4 to 8.1 was reﬂected in a continuum of lichen communities on pines from acidophilous to basiphilous communities. Besides suppressing species richness, understorey density more evidently caused the compositional divergence from neutral bark conditions. The effect of hidden interactions among drivers was explained through reactions of individual species – almost all species across the pollution gradient were pH-limited, whereas species adapted to neutral or alkaline substrate were additionally sensitive to understorey conditions. The hump-shaped distribution of pH niche ranges along the observed niche optima, rather than ecological indicator values, showed that the shape of species’ multi-dimensional niche-space still needs to be quantiﬁed. Conclusions: Each alternative community state along the disturbance gradient represents a realization of its speciﬁc species pool within the meta-pool. Degradation can be deﬁned if the community state is not supported by a meta-pool. Species inﬁltration during community re-assembly can be predicted using species source communities as cost-efﬁcient proxies.

Endolichenic fungi are diverse groups of predominantly filamentous fungi that reside asymptomatically in the interior of lichen thalli. Natural products from endolichenic fungi, isolated from a variety of different lichen species, have been attracting increased attention for their potential to produce bioactive metabolites possessing new structures and representing different structural classes. This is evident from the steady increase of publications devoted to endolichenic fungal metabolites over the past decade, since the first report of endolichenic secondary metabolites. The bioactive metabolites produced by endolichenic fungi originate from multiple biosynthetic pathways and occupy different chemical structure classes, including steroids, quinones, terpenoids, peptides, xanthones, sulfur-containing chromenones, etc. Endolichenic fungal metabolites possess a diverse array of bioactivities, such as anticancer, antiviral, antibacterial, antifungal, and anti-Alzheimer’s disease. This review provides the first thorough assessment of endolichenic fungi, their biodiversity, secondary metabolites, and associated bioactivity. This review will highlight the bioactive metabolites reported in recent years from endolichenic fungi, as well as discussing the potential of these symbiotic fungi as sources of new, diverse natural products with varying bioactivities.

Despite recent regulations, atmospheric ammonia (NH3) emissions have not changed much over the last decades and excessive nitrogen remains as one of the major drivers for biodiversity changes. To prevent deleterious effects on species and ecosystems, it is very important to establish safety thresholds, such as those defined by the Critical Level (CLE) concept, “the concentration above which direct adverse effects on receptors may occur, based on present knowledge.” Empirical critical levels of atmospheric NH3 have mainly been reported for temperate forests and there is a lack of information for Mediterranean forests. Here, we provide a case study on NH3 CLEs for a typical Mediterranean ecosystem, the holm-oak (Quercus ilex) forest. To derive the CLE value, we measured NH3 concentrations for 1 year at a distance gradient in the forest surrounding a point source (cattle farm) and used diversity changes of lichen functional groups to indicate the onset of adverse effects. We estimate a NH3 CLE threshold of 2.6 μg m−3, a value that is higher than that reported in other Mediterranean ecosystems and suggests that the site has been already impacted by NH3 pollution in the past. In a more general context, this study confirms the validity of lichen functional groups to derive CLEs in Mediterranean forests and woodlands and contribute to the body of knowledge regarding the impacts of NH3 on ecosystems.

Intensive forest management has led to a population decline in many species, including those dependent on dead wood. Many lichens are known to depend on dead wood, but their habitat requirements have been little studied. In this study we investigated the habitat requirements of wood dependent lichens on coarse dead wood (diameter >10 cm) of Scots pine Pinus sylvestris in managed boreal forests in central Sweden. Twenty-one wood dependent lichen species were recorded, of which eleven were confined to old (estimated to be >120 years old) and hard dead wood. Almost all of this wood has emanated from kelo trees, i.e. decorticated and resin-impregnated standing pine trees that died long time ago. We found four red-listed species, of which two were exclusive and two highly associated with old and hard wood. Lichen species composition differed significantly among dead wood types (low stumps, snags, logs), wood hardness, wood age and occurrence of fire scars. Snags had higher number of species per dead wood area than logs and low stumps, and old snags had higher number of species per dead wood area than young ones. Since wood from kelo trees harbours a specialized lichen flora, conservation of wood dependent lichens requires management strategies ensuring the future presence of this wood type. Besides preserving available kelo wood, the formation of this substratum should be supported by setting aside P. sylvestris forests and subject these to prescribed burnings as well as to allow wild fires in some of these forests.

Mniaecia jungermanniae, a tiny inoperculate ascomycete growing on leafy liverworts of the order Jungermanniales, was recorded at 66 localities in the Liberec Region (Czech Republic) since December 2013 to May 2015. It was noticed on 17 species of liverworts, with Cephalozia bicuspidata, Calypogeia neesiana, C. azurea and Diplophyllum albicans being the most frequently inhabited ones. The species was recorded on rocks and boulders as well as on soil on forest tracks and along streams, exceptionally on wood. The geological bedrock was acidic in all cases – sandstone, granite or phyllite. The altitude of the localities ranged between 315 and 1215 m a.s.l. Localities were predominantly located in the shade in coniferous and broad-leaved forests, always with a rich occurrence of liverworts. Hitherto known localities in the Czech Republic are also summarised in the article. Key words: bryophilous fungi, Jungermanniales, leafy liverworts, North Bohemia.

(2016): Fungi and lichens recorded during the cryptogam symposium on natural beech forests, Slovakia 2011. - Czech Mycology, 68(1): 1–40.|
In September 2011, an international team of cryptogam experts visited seven national nature reserves in five mountain areas of Slovakia: Havešová and Stužica in the Poloniny Mts., Vihorlat in the Vihorlatské vrchyMts., Oblík in the Slanské vrchyMts., Dobročský prales and Klenovský Vepor in the Veporské vrchy Mts. and Badínsky prales in the Kremnické vrchy Mts. The reserves were selected to represent examples of the best protected old-growth beech forests in the country. The aim was to study the diversity of wood-inhabiting fungi on fallen beech logs and epiphytic lichens on standing beech trees. In total, 215 fungal species and 128 lichens were recorded on beech wood and bark, and 27 fungi and 26 lichens on additional substrates. The site of the highest conservation value is Stužica with 126 fungi and 79 lichens recorded on beech, of which 12 fungi and 19 lichens are indicators of high nature conservation value. Combined with historical records, a total of 19 non-lichenised fungal indicators are now reported from the site, making it the highest ranked natural beech forest in Europe. The second most important reserve for fungal diversity is Havešová with 121 species, including 14 indicator species recorded on beech wood. For lichens, the second most important reserve is Klenovský Vepor with 69 species including 18 lichen indicators recorded on beech. Nine fungus species are here reported as new to Slovakia: Asterostroma medium, Entoloma hispidulum, E. pseudoparasiticum, Gloeohypochnicium analogum, Hohenbuehelia valesiaca, Hymenochaete ulmicola, Hypocrea parmastoi, Melanomma spiniferum and Scutellinia colensoi. Lichen species Alyxoria ochrocheila is reported as new to Slovakia and Lecanographa amylacea, which was considered extinct in the Slovak Red list, was also recorded. This is the first list of wood-inhabiting fungi and epiphytic lichens of old-growth beech forests in Slovakia, and hence an important contribution to the exploration of biodiversity in Slovakia.

In continental Antarctica, algae, fungi, lichen and mosses are the major floristic elements. To understand their distribution and diversity pattern in ice free areas of Schirmacher Oasis and Larsemann Hills investigations were conducted during various Indian Antarctic Expeditions. Due to the extreme environmental conditions in Antarctica, lichens and bryophytes undergo sever morphological changes and occur in mostly in sterile condition that makes them difficult group to identify. A total of 69 species of lichens were encountered in the Schirmacher Oasis and 25 species in the region of Larsemann Hills. Most lichens known from these two areas are microlichens. The ecophysiological studies on lichens indicated Rhizoplaca melanophthalma as the most desiccation tolerant species in Schirmacher Oasis. The studies on moss flora contributed only 12 species under eight genera and five families from Schirmacher Oasis. The sub-fossil moss Pohlia nutans of Holocene period was recorded from lake sediment cores from Schirmacher Oasis. There are several studies on algal flora of Schirmacher Oasis and in one of the studies a total of 109 species of cyanobacteria belonging to 30 genera and 9 families were recorded from Schirmacher Oasis. Similarly, a total of 19 species of fungi belonging to 13 genera and seven families were recorded from Schirmacher Oasis soils and 5 species of yeasts were recorded from Larsemann Hills. Furthermore, Thelebolus microsporus was characterized for adaptation strategies and biotechnological potentials. Schirmacher Oasis; Larsemann Hills; Algae; Fungi; Moss; Lichens; Antarctica

Two glycoproteins were purified and biochemically characterized from the lichen X. parietina. Both behaved as enzymes with arginase activity and haemaglutinins. Secreted arginase (SA) contained galactose and glucose in the saccharide moiety and an isoelectric point of 4.54. The algal binding-protein (ABP) had N-acetyl-glucosamine and glucose as glycosidic residues and an isoelectric point of 3.53. Both proteins had the same molecular mass (58.6 kDa) and the same qualitative amino acidic composition. The results allowed us to consider these glycoproteins as isolectins, which have significant physiological roles in the relationship between photobiont and mycobiont of symbiotic association. Keywords: Algal binding-protein; Glycoprotein; Isolectins; Secreted arginase.

Lichens, symbiotic organisms with special features, are able to synthesize exclusive secondary metabolites that are attracting increasing interest in their pharmacological activities. Present study aimed to perform an initial screening of the antioxidant capacities of 29 lichens from Parmeliaceae family, and the cytoprotective potential of the most promising species in a model of central nervous system-like cells. Also, another goal was to determine the main chemical constituents of the promising lichens. After molecular identification of all lichen specimens by PCR techniques regarding the molecular marker ITS rDNA, antioxidant activity was measured in terms of free radical scavenging properties through ORAC assay. Methanol extracts of the three species with highest ORAC values (Cetrelia braunsiana (Cb), Parmotrema saccatilobum (Ps) and Usnea ghattensis (Ug)) were analyzed for phytochemical characterization through TLC and HPLC methods. We identified alectoronic acid as major metabolite in Cb, protocetraric acid in Ps and usnic, stictic and constictic acids in Ug. Concerning cytoprotective properties, their extracts were tested on human neuroblastoma cell line SH-SY5Y. Protection against H2O2- induced oxidative stress in such neuronlike model was assessed by cell viability assays, thus determining their optimal concentrations. Then, their effect on oxidative stress markers, such as intracellular ROS formation, glutathione levels and caspase-3 activity, were evaluated. In general, lichens extracts were able to reverse the oxidative damage caused by H2O2, and promoted neurons survival. Results obtained in this study imply that these lichen species might be used as promising sources for natural compounds with potential neuroprotective activity, suggesting future research avenues.

Candida albicans is a commensal coloniser of the human gastrointestinal tract and an opportunistic pathogen, especially thanks to its capacity to form biofilms. This lifestyle is frequently involved in infections and increases the yeast resistance to antimicrobials and immune defenses. In this context, 38 lichen acetone extracts have been prepared and evaluated for their activity against C. albicans planktonic and sessile cells. Minimum inhibitory concentrations of extracts (MICs) were determined using the broth microdilution method. Anti-biofilm activity was evaluated using tetrazolium salt (XTT) assay as the ability to inhibit the maturation phase (anti-maturation) or to eradicate a preformed 24 h old biofilm (anti-biofilm). While none of the extracts were active against planktonic cells, biofilm maturation was limited by 11 of the tested extracts. Seven extracts displayed both anti-maturation and anti-biofilm activities (half maximal inhibitory concentrations IC50_mat and IC50_biof 100 g/mL); Evernia prunastri and Ramalina fastigiata were the most promising lichens (IC50_mat < 4 g/mL and IC50_biof < 10 g/mL). Chemical profiles of the active extracts performed by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC) have been analyzed. Depsides, which were present in large amounts in the most active extracts, could be involved in anti-biofilm activities. This work confirmed that lichens represent a reservoir of compounds with anti-biofilm potential. Keywords: lichens; biofilm; Candida albicans; screening; chemical profiling.

New organic filler, obtained from a local lichen type, Rinodina Poeltii, was utilized in low density polyethylene (LDPE). Thermal characterization of organic filler revealed its suitability to be used as filler during extrusion and injection processes. Filler did not exhibit any weight loss up to 300°C except the dehydration loss at 155°C. Unmodified filler was compounded as 5, 10, and 15% by weight with LDPE. Filler addition resulted in a decrease for both tensile strength and % elongation at break. However, an increase was observed in elastic modulus. The compatibility of the filler material and polymer matrix was also found to be good as a result of absence of pull out voids in SEM observation.

This study demonstrates the applicability of Raman spectroscopy, assisted with X‐ray fluorescence and scanning electron microscopy–energy dispersive X‐ray spectroscopy analyses, in the characterization of biominerals accumulated on several stone materials colonized by saxicolous lichens under different environmental conditions. The distribution of the diverse biominerals through the lichen–stone interface is described. Among them, neogenerated biominerals involved in the metabolism of Caloplaca and Lecanoraceae lichen genera such as calcium oxalates in their two hydrated forms were found in different parts of the lichen, even on sandstones that X‐ray spectroscopy evidenced the absence of calcium in their mineralogical composition. Hence, it is demonstrated the atmospheric intake likely as particulate matter composed of calcite. The occurrence of the calcium oxalates is shown not to be related to the environmental conditions but to the lichen genera, because no common patterns were observed in the studied specimens. Moreover, several carbonates like calcite (CaCO3), ankerite (FeCa(CO3)2) and dolomite (CaMg(CO3)2) were identified only in the lichen thallus vicinity. These evidences are described by means of Raman spectroscopy for the first time. The biominerals accumulated on several stone materials colonized by saxicolous lichens living under different environmental conditions are characterized. The work describes the calcium oxalate distribution on the surface of caloplaca and lecanoraceae lichen genera and demonstrates the neogenesis of calcium oxalates on non carbonated stones (where X‐ray spectroscopy evidenced the absence of calcium) suggesting an atmospheric uptake. It is noticeable the detection of calcite (CaCO3), ankerite (FeCa(CO3)2) and dolomite (CaMg(CO3)2) in the vicinity of the lichen thalli. These evidences are described by means of Raman spectroscopy for the first time. Keywords: lichens; Raman spectroscopy; calcium oxalates; ankerite; dolomite; calcite.

Lichens are one of the most common air quality bioindicators. Airborne heavy metal pollution causes various physiological changes in lichens, but sensitivity to metal pollution is species speciﬁ c. In this research, three lichen species (Parmelia sulcata, Flavoparmelia caperata and Evernia prunastri) were exposed to cadmium (50 mg L–1) in laboratory conditions. Photosynthetic efﬁ ciency of photosystem II and content of secondary metabolites were determined after one, three and eight days of exposure. In all investigated species treatment of lichen thalli with cadmium signiﬁ cantly changed Fv/Fm and RFd only after eight days of exposure. Quantiﬁ cation of metabolites showed a decreased content of the medullary depsidones salazinic acid (in P. sulcata) and protocetraric acid (in F. caperata) but increased content of cortical depside atranorin (in P. sulcata) and dibenzofurane usnic acid (in F. caperata) after cadmium exposure. However, no changes in secondary metabolites were found in E. prunastri. Results show that investigated species are relatively resistant to short-term cadmium-exposure and that secondary metabolites could have an important role in the protection of primary metabolism from negative cadmium impacts, at least in some species. Key words: air pollution, heavy metal, HPLC, photosynthesis.

Paper presents the results of the investigations of the calcicolous lichen flora occuring in the Sudety Mts. The study was carried out in the two most extensive areas with calcareous substrates in the Sudety Mts: the Góry Kaczawskie Mts in the western part of the Sudetes and the Śnieżnik Metamorphic Region in their eastern part, and the two types of localities: natural rock outcrops and quarries. On each locality the entire lichen flora that was directly (saxicolous species) or indirectly (terricolous and muscicolous species) associated with calcareous substrates was analyzed. Of the 129 species currently found in the study area, 84 species were exclusively epilithic, 17 were epilithic, 21 species grew over mosses and 22 taxa were not connected with only one type of substrate. The calcicolous lichen flora of the Western Sudety Mts was significantly richer and more diverse than that of the Eastern Sudetes. In the Góry Kaczawskie Mts a total of 111 calcicolous lichen species were found, whereas in the Śnieżnik Metamorphic Region only 72 species were identified during the study. Only 54 taxa occured in both calcareous areas in the Sudety Mts. Key words: saxicolous lichens, calciphilous lichens, Sudety Mts, Lower Silesia.

Limestone is a distinctive substrate that has significant effects on soils and plants. The present study characterizes the diversity of vascular plants, bryophytes, and lichens at the Simonton Corner Quarry Preserve, an abandoned limestone quarry in Rockport, Maine, USA, which was in operation in the late 1800s. We document vascular plant diversity and associated edaphic features (i.e., soil pH and elemental chemistry) using 30 535 meter plots spread throughout the site. For vascular plants, 114 species in 96 genera and 50 families were observed; few of these species are known to prefer calcareous environments, and 38% are nonnative. Conversely, the soiland rock-dwelling cryptogam biota, which comprises 21 moss species in 13 families and eight lichen species in three families, contains many calciphilic species. The bryoflora conspicuously lacks liverworts, whereas the lichen biota is dominated by cyanolichens. This study will inform future conservation and reclamation work at this and other human-altered limestone sites in Maine and floristically similar areas and contribute to our understanding of the geoecology of New England. Key Words: bryophytes, carbonate floras, edaphic factor, geobotany, lichens, limestone, plant-soil relations.

The Adirondack Mountains of New York State hold some of the southernmost communities of alpine vegetation in the eastern United States. Containing the greatest concentration of rare and endangered species in New York State, this ,12,000-year-old ecosystem is important to understanding the ecological history of northeastern North America. In order to monitor floristic and vegetational shifts over time, 11 permanent transects were established in 1984 on four summits (Wright, Algonquin, Boundary, and Iroquois) of the MacIntyre Range in the Adirondack High Peaks region. Using the point-intercept method, all 11 transects were sampled in 1984, 1994, 2002, and 2007. Vegetation composition changed significantly over the 23-year period, with an overall decrease in bryophytes/lichens and an increase in vascular plants, indicating that vascular plants were replacing bryophytes, particularly in areas not disturbed by hikers. Community similarity was high among all transects, and increased with time for vascular plants as they became more abundant, indicating a successional convergence. Compositional shifts may also reflect effects of global warming and atmospheric deposition on alpine plant communities. Key Words: alpine flora, vegetation change, succession, bryophytes, Adirondack Mountains, permanent transect.

Four years after a trench was dug through alpine habitat on Mount Washington, New Hampshire, we surveyed vascular plants, bryophytes, and lichens in the disturbed area, analyzing species richness and abundance compared with values in adjacent, undisturbed areas. Plants had begun recolonizing the disturbed area, but species richness and abundance remained far lower than in the undisturbed community. Among vascular plants, graminoids colonized most quickly, and woody species were largely absent. Species with the highest frequency and greatest abundance in the disturbed area also were common and abundant in the undisturbed community. Bryophytes appeared to be colonizing no more quickly than vascular plants. Treeline and elevation exerted separate effects on community structure and recovery. Treeline influenced species richness, abundance, and the rate of recovery of vascular plants, but there was no evidence of an additional effect of elevation either above or below treeline. Treeline also influenced species richness of bryophytes and lichens. In addition, elevation appeared to have a separate effect on their rate of recovery in alpine habitat: species richness of bryophytes and lichens declined with elevation in the disturbed community but not in the undisturbed community. This suggests that elevation has a transient effect on colonization and/or survival, but only above treeline. In general, recovery has occurred more quickly below treeline. This survey establishes baseline information that will be useful in assessing the rate of recovery after future surveys. Key Words: alpine plants, disturbance recovery, global climate change, vascular plants, bryophytes, lichens, Presidential Range, White Mountain National Forest, succession.

Quantitative data on the abundance and frequency of vascular plants, bryophytes and lichens are lacking for alpine snowbed and rill communities in northeastern North America. Such data are needed to establish whether the communities are changing in response to climate warming, nitrogen deposition or shifts in the timing of precipitation and snowmelt. We surveyed nine sites (five snowbeds and four rills) on Mount Washington (White Mountain National Forest, New Hampshire), recording 54 vascular plant species, 42 bryophytes and 13 lichens. Although vascular plants were most abundant, bryophytes and lichens, which had not been completely surveyed in these communities previously, were important in terms of species richness (as many as eight bryophytes and four lichens in 1 m2 quadrats) and were occasionally abundant, particularly bryophytes in rills. We found that snowbeds and rills are separate communities. Some species are shared, but far higher numbers of vascular plants, bryophytes and lichens were found in one community but not the other. The most frequent vascular plants had been reported as common in snowbeds and rills previously. However, several species that are common in these communities elsewhere occurred less often in our sites because of variation occurring both across the region and within the White Mountains. Our research provides baseline information on snowbeds and rill plant communities so that future studies can determine how they respond to changes in environmental conditions. Key Words: alpine ecology, bryophytes, climate change, community dynamics, lichens, species richness.

The lichens of Prince Edward Island (PEI) are well known to have been inadequately sampled and not well understood. In this study, 19 biologically diverse forest remnants and other potentially rich localities were explored for their lichen vegetation, and 118 new county records and 71 species new for the province were discovered. Together with previously studied sites, 38 localities in total have now been surveyed. A new checklist based on these surveys was prepared for all the lichens of the island. In addition, conservation status (S-ranks) is proposed for 153 species of the 326 species in 118 genera now known for the province. Four species received a rank of S1 (critically imperiled): Anaptychia crinalis, Megaspora verrucosa, Pannaria lurida, and Sclerophora amabilis; and six species received a rank of S2 (imperiled): Acrocordia cavata, Bryoria salazinica, Heterodermia speciosa, Menegazzia terebrata, Pannaria rubiginosa, and Ramalina thrausta. The importance of baseline data for future conservation planning, pollution monitoring, and climate change studies is emphasized. Key Words: Biogeography, phytogeography, rare species, sustainable management, old-growth forests, forest.

This paper contributes to studies on the lichen biota of Arctic glacier forelands. The research was carried out in the moraines of three different glaciers in Svalbard: Longyearbreen, Irenebreen and Rieperbreen. In total, 132 lichen taxa and three lichenicolous lichens were recorded. Eight species were recorded for the first time in the Svalbard archipelago: Arthonia gelidae, Buellia elegans, Caloplaca lactea, Cryptodiscus pallidus, Fuscidea kochiana, Merismatium deminutum, Physconia distorta, and Polyblastia schaereriana. One species, Staurothele arctica, was observed for the first time in Spitsbergen (previously recorded only on Hopen island). All the studied glaciers lie in Spitsbergen’s warm region. However, Kaffiøyra Plain, where Irenebreen is located, is characterized by higher levels of humidity, which may explain its different lichen composition compared to that of the other two moraines. The forelands of Rieperbreen and Longyearbreen are located in the same area of Svalbard, which is also the warmest and the driest and where high species diversity is expected. This proved to be true for the Rieperbreen moraine, but not for the Longyearbreen moraine, where species diversity was lowest. The expansion of tourism along Longyearbyen appears to be a major factor behind the poor development of lichen biota on the Longyearbreen moraine. Key-words: Arctic / Irenebreen / Rieperbreen / Longyearbreen / species richness.

Cliffs harbor unique ecological communities while facing increasing pressure from human disturbances. How abiotic factors such as surface heterogeneity, slope, and aspect interact locally to drive variation in plant communities remains largely unknown. We surveyed the vascular plants, bryophytes, and lichens along 50 vertical transects throughout the Big South Fork National River and Recreation Area (Tennessee, USA) to characterize the vegetative community and to determine which factors influenced the distribution of cliff vegetation. Across all cliff face plots, the dominant lichen genus was Lepraria; the dominant vascular plant was Dennstaedtia punctilobula; and the dominant bryophyte was Dicranum montanum. We found several rare species including Cladonia pocillum, a boreal disjunct lichen; Vittaria appalachiana, Appalachian shoestring fern; and Cynodontium schisti, a rare bryophyte. Vascular plants, bryophytes, and lichens were each influenced by different environmental drivers. West-facing slopes supported high vascular plant diversity, low-angle slopes supported high bryophyte diversity, and faces with high surface heterogeneity supported high lichen diversity. Both plant and lichen communities varied widely by transect within and across sampling areas. Recreational rock climbing did not appear to influence community structure, possibly due to low levels of climbing traffic among our survey transects. Nonetheless, we overlapped our vegetative model with a simple spatial model of potential for rock climbing development to highlight specific areas of concern. Our predictive model of vegetative diversity was moderately accurate (ρ = 0.43), suggesting that surveying each cliff individually may be necessary for conservation efforts. In addition, our work indicated that preserving vegetation along the top of cliff faces should remain a focus of conservation efforts. Index terms: cliff ecology, rock climbing, spatial modeling, Shannon’s diversity.

Sandstone glades in the Ozark highlands contain unique communities of vascular plants, including several species of conservation concern, as well as abundant communities of terricolous cryptogams—collectively termed biological soil crusts. Biological soil crusts have important ecological roles in grassland systems, such as preventing erosion and retaining soil moisture. Despite the conservation importance of sandstone glades, this ecosystem has received little scientific attention, and the drivers of plant diversity and soil crust prevalence in sandstone glades are poorly understood. In this study, we assessed relationships between soil crust cover and vascular plant species richness and tested whether dominance shifts from soil crusts to vascular plants along a soil gradient. Soil crust cover was negatively related to vascular plant species richness, and vascular plant richness increased (and crust cover decreased) with increasing soil organic matter. As soil organic matter increased, the proportion of perennial vascular plants in the community also increased. These results provide some of the first quantitative evidence for drivers of plant diversity patterns in Ozark sandstone glades and suggest that soil characteristics have an important role in structuring the distributions of plants and crusts in sandstone glades. Key words: biological soil crusts, edaphic communities, lichens, outcrop communities, plant diversity.

Our development of lichen elemental bioindicators for a United States of America (USA) national monitoring program is a useful model for other large-scale programs. Concentrations of 20 elements were measured, validated, and analyzed for 203 samples of five common lichen species. Collections were made by trained non-specialists near 75 permanent plots and an expert near nine air monitoring sites. Flavoparmelia caperata (most frequent) and Physcia aipolia/stellaris between them represented the full range of local forest cover and pollution load. Evernia mesomorpha (values saturated at intermediate pollution), Parmelia sulcata, and Punctelia rudecta (both difficult for non-specialists) were less useful. Conversion models (GLM or regression) rendered elemental data equivalent between species. Al, Cr, Cu, Fe, Hg, N, and S, plus composite indexes from them, were linked with local air pollution based on correlations with directly measured N and particulate matter as well as from PCA; elements were weakly correlated with modeled pollution estimates. Lichen Hg had no other useful surrogates. Invoking multiple causation and scale-dependence helped address several issues of interpretation, for instance conflicting bioindicator value of Al and Fe from literature.

Development of the Athabasca Oil Sands Region in northeastern Alberta, Canada has contributed polycyclic aromatic hydrocarbons (PAHs) and polycyclic aromatic compounds (PACs), which include alkyl PAHs and dibenzothiophenes, to the regional environment. A new analytical method was developed for quantification of PAHs and PACs in the epiphytic lichen bioindicator species Hypogymnia physodes for use in the development of receptor models for attribution of PAH and PAC concentrations to anthropogenic and natural emission sources. Milled lichens were extracted with cyclohexane, and extracts were cleaned on silica gel using automated solid phase extraction techniques. Quantitative analysis was performed by gas chromatography with selected ion monitoring (GC-SIM-MS) for PAHs, and by GC with time-of-flight mass spectrometry (GC-TOF-MS) for PACs. PACs were quantitated in groups using representative reference compounds as calibration standards. Analytical detection limits were ≤2.5 ng g−1 for all individual compounds. Precision as measured by laboratory duplicates was variable; for individual analytes above 5 ng g−1 the mean absolute difference between duplicates was typically <20%. Selection of single-analyte markers for source attribution should include consideration of data quality indicators. Use of TOF-MS to spectrally characterize PAC group constituents identified significant challenges for the accurate quantitation of PACs with more than two carbons in their side chain(s). Total PAH concentrations in lichen samples ranged from 12 to 482 ng g−1. Total PACs in each sample varied from a fraction of total PAHs to more than four times total PAHs. Results of our analyses of H. physodes are compared with other studies using other species of lichens as PAH receptors and with passive monitoring data using polyurethane foam (PUF) samplers in the Athabasca Oil Sands Region (AOSR). This study presents the first analytical methodology developed for the determination of PACs in an epiphytic lichen bioindicator species.

Forest managers in many parts of the world are charged with protecting rare lichen species, including species growing near their range limits. Rare lichens may be particularly vulnerable to effects of climate change, and conserving lichen diversity necessitates understanding factors that limit species distributions. Habitat suitability envelopes for lichens are shifting as the climate changes, but it is unclear whether and how local (e.g., within-tree) lichen species distributions will shift. Conserving lichen biodiversity also requires effective field surveys to detect and monitor rare lichen populations. However, the reliability of rare lichen survey methods currently used across global forest lands is rarely tested. In this study, we quantify the canopy distribution of an epiphytic old-growth forest cyanolichen near its southern range limit and test whether ground surveys reliably detect canopy populations. Near its southern range limit, Lobaria oregana was most abundant in two distinct zones within tree crowns: on branches of large trees in the mid-crown, and on boles of small trees near ground level. The abundance of this species near ground level suggests that lichens may benefit from cooler, wetter microclimates near the equatorial edges of their ranges. Maintaining these microclimate habitats may be a key to long-term viability of rear edge lichen populations. Targeted ground surveys reliably detected L. oregana in litterfall underneath trees where it was abundant in the crowns. However, ground surveys did not reliably detect the lichen underneath trees when it occurred in the crowns in low abundance. Our results suggest that ground surveys are useful for characterizing abundant lichen species, but that canopy surveys (e.g., tree climbing) may be needed to reliably detect lichens when they occur at low abundance.

It has been widely shown that nuclear fallout includes substances, which accumulate in organisms such as crustaceans, fish, mushrooms and lichens, helping to evaluate the activity concentration of contaminants accumulated on a long time. In this context, radiocaesium deposited in soil following the Chernobyl accident on 26 April 1986 is known to have remained persistently available for plant uptake in many areas of Europe. Studies on the lichen Stereocaulon vesuvianum show the plant's high capacity to retain radionuclides from the substrate and the air. After the Chernobyl accident, starting from September 1986, at the Radioactivity Laboratory (LaRa) of the University of Naples Federico II, four monitoring campaigns to evaluate the activity concentration of four isotopes of the two elements caesium and ruthenium (134Cs, 137Cs, 103Ru and 106Ru) were carried out until 1999. This study allowed the effective half-life of 134Cs and 137Cs to be estimated. Twenty-eight years after the accident, in December 2014, a further sampling was carried out; only 137Cs was revealed beyond the detection limits, measuring activity concentrations ranging from 20 to 40 Bq/kg, while the other radionuclides were no longer observed due to their shorter half-life. The last sampling allowed more precise determination of the effective half-life of 137Cs (6.2 ± 0.1 year), due to the larger dataset on a large time period.

(2017): Refugial ecosystems in central Asia as indicators of biodiversity change during the Pleistocene–Holocene transition. - Ecological Indicators, 77: 357–367.|
Highlights: • Relict ecosystems in central Asia preserve many features of Pleistocene ecosystems. • We use them as indicators of species-richness patterns of Pleistocene landscapes. • Vascular-plant and land-snail richness was lower in Pleistocene-like landscapes. • Bryophyte and lichen richness was higher in Pleistocene-like landscapes. • Modern analogs are useful indicators of the past biodiversity changes. Site-scale species richness (alpha diversity) patterns are well described for many present-day ecosystems, but they are difficult to reconstruct from the fossil record. Very little is thus known about these patterns in Pleistocene full-glacial landscapes and their changes following Holocene climatic amelioration. However, present-day central Asian ecosystems with climatic features and biota similar to those of the full-glacial periods may serve as proxies of alpha diversity variation through both space and time during these periods. We measured alpha diversity of vascular plants, bryophytes, macrolichens and land snails, as well as environmental variables, in 100-m2 plots located in forests and open habitats in the Russian Altai Mountains and their northern foothills. This region contains adjacent areas that possess climatic and biotic features similar to mid-latitude Europe for both the Last Glacial Maximum and contemporaneous Holocene ecosystems. We related alpha diversity to environmental variables using generalized linear models and mapped it from the best-fit models. Climate was identified as the strongest predictor of alpha diversity across all taxa, with temperature being positively correlated to number of species of vascular plants and land snails and negatively correlated to that of bryophytes and macrolichens. Factors important for only some taxa included precipitation, soil pH, percentage cover of tree layer and proportion of grassland areas in the landscape around plots. These results, combined with the high degree of similarity between the current Altai biota and dry-cold Pleistocene ecosystems of Europe and northern Asia, suggest that vascular plant and land snail alpha diversity was low during cold phases of the Pleistocene with a general increase following the Holocene climatic amelioration. The opposite trend probably existed for terricolous bryophytes and macrolichens.

(2017): SOS response in bacteria: Inhibitory activity of lichen secondary metabolites against Escherichia coli RecA protein. - Phytomedicine, 29: 11–18.|
Background: RecA is a bacterial multifunctional protein essential to genetic recombination, error-prone replicative bypass of DNA damages and regulation of SOS response. The activation of bacterial SOS response is directly related to the development of intrinsic and/or acquired resistance to antimicrobials. Although recent studies directed towards RecA inactivation via ATP binding inhibition described a variety of micromolar affinity ligands, inhibitors of the DNA binding site are still unknown. Purpose: Twenty-seven secondary metabolites classified as anthraquinones, depsides, depsidones, dibenzofurans, diphenyl-butenolides, paraconic acids, pseudo-depsidones, triterpenes and xanthones, were investigated for their ability to inhibit RecA from Escherichia coli. They were isolated in various Chilean regions from 14 families and 19 genera of lichens. Methods: The ATP hydrolytic activity of RecA was quantified detecting the generation of free phosphate in solution. The percentage of inhibition was calculated fixing at 100 µM the concentration of the compounds. Deeper investigations were reserved to those compounds showing an inhibition higher than 80%. To clarify the mechanism of inhibition, the semi-log plot of the percentage of inhibition vs. ATP and vs. ssDNA, was evaluated. Results: Only nine compounds showed a percentage of RecA inhibition higher than 80% (divaricatic, perlatolic, alpha-collatolic, lobaric, lichesterinic, protolichesterinic, epiphorellic acids, sphaerophorin and tumidulin). The half-inhibitory concentrations (IC50) calculated for these compounds were ranging from 14.2 µM for protolichesterinic acid to 42.6 µM for sphaerophorin. Investigations on the mechanism of inhibition showed that all compounds behaved as uncompetitive inhibitors for ATP binding site, with the exception of epiphorellic acid which clearly acted as non-competitive inhibitor of the ATP site. Further investigations demonstrated that epiphorellic acid competitively binds the ssDNA binding site. Kinetic data were confirmed by molecular modelling binding predictions which shows that epiphorellic acid is expected to bind the ssDNA site into the L2 loop of RecA protein. Conclusion: In this paper the first RecA ssDNA binding site ligand is described. Our study sets epiphorellic acid as a promising hit for the development of more effective RecA inhibitors. In our drug discovery approach, natural products in general and lichen in particular, represent a successful source of active ligands and structural diversity.

Lichens species produce unique secondary metabolites that attract increasing pharmacological interest, including their redox modulatory activities. Current work evaluated for the first time the in vitro cytoprotective properties, based on the antioxidant activities, of the Parmeliaceae lichens Evernia prunastri and Usnea ghattensis and the mechanism of action of their major phenolic constituents: the evernic and usnic acids, respectively. In two models of central nervous system-like cells (U373-MG and SH-SY5Y cell lines), exogenous H2O2 induced oxidative stress-mediated cytotoxicity. We first assessed their radical scavenging capacities (ORAC and DPPH tests) and the phenolic content of the extracts. At the optimal concentrations, pretreatments with evernic acid displayed significant protection against H2O2-induced cytotoxic damage in both models. It reversed the alterations in oxidative stress markers (including ROS generation, glutathione system and lipid peroxidation levels) and cellular apoptosis (caspase-3 activity). Such effects were in part mediated by a notable enhancement of the expression of intracellular phase-II antioxidant enzymes; a plausible involvement of the Nrf2 cytoprotective pathway is suggested. Usnic acid exerted similar effects, to some extent more moderate. Results suggest that lichen polyketides evernic and usnic acids merit further research as promising antioxidant candidates in the therapy of oxidative stress-related diseases, including the neurodegenerative disorders. Keywords: Parmeliaceae lichens Evernic acid Usnic acid oxidative stress neuroprotection.

Several studies carried out after the Chernobyl nuclear accident in 1986 showed that lichens are suitable biomonitors of the fall-out, given their long life expectancy. 137Cs activity concentrations were measured through HPGe gamma spectrometry in different epiphytic lichens (Usnea SPP, Platismatia glauca, Pseudevernia furfuracea, Ramalina SPP), collected from three sampling sites in the Calabria region, south of Italy. Data on variations in the contents of airborne particulates heavy metals, As, Be, Cd, Cu, Hg, Pb and Zn, measured in the thalli of the investigated lichens through inductively coupled plasma mass spectrometry (ICP-MS), were reported in accordance with a lichen thalli naturalness/alteration scale. Energy-dispersive X-ray microanalysis in a scanning electron microscope (SEM-EDX), with an electron beam of 20 keV, that interacts with the sample leading to the emission of characteristic X-rays as secondary radiation, was also employed to investigate about the chemistry of the adherent particles to the surface of investigated lichens and about the possible interaction between them and the surrounding environment. Data obtained in this article provide useful information on the environmental risk of the studied area and can be further used for a radiological and chemical mapping.

There is ample evidence for species distributional changes in response to recent climate change, but most studies are biased toward better known taxa. Thus, an integrated approach is needed that includes the “cryptic diversity” represented partly by lichens, which are among the most sensitive organisms to environmental change due to their physiological characteristics. The use of functional traits and ecological attributes may improve the interpretation of how species respond to climate change. Thus, we quantified the future climate change impacts on 41 lichen species distributed in the Iberian Peninsula using ensemble climatic suitability maps (derived from generalized linear and generalized additive models, and classification and regression tree analysis) and different metrics. We also determined the lichen traits/attributes that might be related to a shared response to climate change. The results indicated a loss of bioclimatic space for 75% of the species studied and an increase for 10 species, especially in Mediterranean ones. Most of the species that will lose more than 70% of their current modeled distribution area comprised big macrolichens with cyanobacteria as the photobiont, thereby indicating a great biomass loss in forests, which might affect nutrient cycles. We also found that the predicted distributions were trait-related. Smaller species, green-algae lichens, and saxicolous and epiphyte species will respond better to future climate change. The results of this type of study may help to identify the species that are most vulnerable to climate change and facilitate the development of conservation measures to avoid their decline.

The extent to which small shifts among local topographic microsites could mitigate the effects of larger-scale climate change in arctic–alpine systems including mountain top organisms is largely unknown. This study is among the first to evaluate the relative contribution of microsite and altitude as a proxy for climate change on saxicolous lichen communities. We registered 107 lichen species in 54 boulders ranging from 900 to 2700 m.a.s.l. and in a large array of microsites in central Argentina. Communities ordinated along NMS multivariate analysis axes 1, 2 and 3 presented a cumulative R2 of 80%. The three axes were explained by altitude with axis 1 only being explained by altitude. Axis 2 was also explained by slope and aspect whereas axis 3 was explained by the interaction of altitude with aspect indicating that aspect was important only at lower altitudes but not at the mountain top. Lichen cover and richness were similar throughout the altitudinal gradient. We interpret that under a climate warming scenario, lower altitude species occupying pole ward facing slopes will have to migrate upwards while at the mountain top—for most communities—there still is scope for microsite segregation to compensate climate change.

Highlights: • Lichen transplants allow easy and detailed environmental pollution data collection. • Two-month exposed samples were enriched with magnetite-like magnetic minerals. • Magnetic parameters and content of selected elements were correlated. • Magnetic properties are good proxies also for low levels of heavy metal pollution. The aim of this study was to verify whether it is possible to discriminate between the different pollution sources present in a mixed land use area of NE Italy on the basis of the magnetic properties and the element content of lichen transplants. Thalli of Pseudevernia furfuracea were collected in a pristine area of the South-Eastern Alps and exposed for 2 months in 40 sites located at the knots of a 700 m step grid covering ca. 40 km2 of a mosaic of agricultural, forested, industrial and urban areas. In this way, the samples could be analyzed after a defined period of time, and compared to pre-exposure conditions. The post-exposure element content and the magnetic data substantially agreed, revealing a rather modest anthropogenic impact on the territory, mostly limited to an industrial park. Since the magnetic mineralogy was homogeneous throughout the entire set of samples, with magnetite-like minerals as the main magnetic carriers, it was not possible to discriminate betweenPMoriginating fromthe different pollution sources. The contribution given by the industrial park could be confirmed by the multivariate analysis of the element data set. Conversely, it was possible to assess the lowenvironmental impact of the largest local industry, a cement plant, located outside the industrial park. Notwithstanding the relatively short time of the survey, P. furfuracea was proven to be an effective accumulator for biomagnetic monitoring studies, its magnetic properties being excellent proxies for heavy metal pollution evenwhen the anthropogenic impact on the territory is low.

Geochemistry and mineralogy of rocks play important roles in the occurrence of individual lichen species and assembly of lichen communities. Whereas lichens of metal-enriched settings have been a focus of study for many decades, only a few such lichen inventories exist for North America. We reexamined the lichen biota of Pine Hill, a serpentine outcrop on Little Deer Isle, Maine and Callahan Mine, a copper- and zinc-enriched Superfund site in Brooksville, Maine by conducting additional field surveys and reexamining unidentified taxa from previous collections. To better characterize the substrates upon which the lichens were found, we conducted elemental analyses via x-ray fluorescence and inductively coupled plasma-mass spectrometry on rock samples collected at Pine Hill and recorded pH, electrical conductivity, and elemental concentrations via inductively coupled plasma mass spectrometry on soil samples from Callahan Mine. The re-investigation of lichens of the two metal-enriched sites resulted in the addition of 20 taxa to Pine Hill and 10 taxa to Callahan Mine. These include Dermatocarpon leptophyllodes, Placynthiella hyporhoda, Pyrenocarpon thelostomum, and Vezdaea acicularis, all recorded for the first time from New England. In addition, we report the first documented records since the late 19th to early 20th century for New England of Porocyphus coccodes, Sarcosagium campestre, and Steinia geophana, and the first such record for Maine for Coccocarpia palmicola.

The geographical distribution of species affects their dietary traits relative to resources available in different lati- tudes. Dietary traits of Rangifer tarandus, a species with a wide geographical distribution, were investigated using tooth mesowear and microwear methods in eight extant populations from Canada. The data show a latitudinal shift corresponding to a vegetational gradient from the taiga to the tundra, i.e. an increase of lichen consumption from the low to the high latitudes. This pattern is also evidenced in the Pleistocene fossil record of Europe where R. tarandus populations from low latitude localities show a lower consumption of lichen than at higher latitudes.

Unraveling the complex relationship between lichen fungal and algal partners has been crucial in understanding lichen dispersal capacity, evolutionary processes, and responses in the face of environmental change. However, lichen symbiosis remains enigmatic, including the ability of a single fungal partner to associate with various algal partners. Psora decipiens is a characteristic lichen of biological soil crusts (BSCs), across semi-arid, temperate, and alpine biomes, which are particularly susceptible to habitat loss and climate change. The high levels of morphological variation found across the range of Psora decipiens may contribute to its ability to withstand environmental change. To investigate Psora decipiens acclimation potential, individuals were transplanted between four climatically distinct sites across a European latitudinal gradient for 2 years. The effect of treatment was investigated through a morphological examination using light and SEM microscopy; 26S rDNA and rbcL gene analysis assessed site-specific relationships and lichen acclimation through photobiont switching. Initial analysis revealed that many samples had lost their algal layers. Although new growth was often determined, the algae were frequently found to have died without evidence of a new photobiont being incorporated into the thallus. Mycobiont analysis investigated diversity and determined that new growth was a part of the transplant, thus, revealing that four distinct fungal clades, closely linked to site, exist. Additionally, P. decipiens was found to associate with the green algal genus Myrmecia, with only two genetically distinct clades between the four sites. Our investigation has suggested that P. decipiens cannot acclimate to the substantial climatic variability across its environmental range. Additionally, the different geographical areas are home to genetically distinct and unique populations. The variation found within the genotypic and morpho-physiological traits of P. decipiens appears to have a climatic determinant, but this is not always reflected by the algal partner. Although photobiont switching occurs on an evolutionary scale, there is little evidence to suggest an active environmentally induced response. These results suggest that this species, and therefore, other lichen species, and BSC ecosystems themselves may be significantly vulnerable to climate change and habitat loss. Keywords: biological soil crusts, environmental change, Europe, genetic diversity, green algae, latitudinal gradient, morphological variability, Myrmecia, plant–climate interactions, plasticity.

Teloschistaceae, one of the largest families of lichenized fungi, has its known Eurasian diversity hot-spots in the Mediterranean basin and in arid continental territories. The Caucasus is a natural boundary between these territories and the diversity of Teloschistaceae is therefore expected to be high in this region. We studied the easternmost part of the Caucasus, Dagestan, a region neglected by lichenologists in the past, but with recent lichenological activity. We provide here a checklist of 85 species of Teloschistaceae, 39 of them new to Dagestan from our field work in 2015, and four species new to Russia (Athallia nesodes, "Caloplaca" emilii, "Caloplaca" xerica and Gyalolechia epiphyta). This total is higher than the numbers known from some well-surveyed Central European countries, but lower than numbers reported from Mediterranean countries. It suggests a rather high diversity of Teloschistaceae in Dagestan, although the absence of well-developed maritime and Mediterranean habitats (which are usually rich in species of Teloschistaceae) precludes an even higher diversity. Key words: Caloplaca, diversity potential, Russia, Variospora, Xanthocarpia.

Rhizoplaca melanophthalma s.l. is a group of morphologically distinct and chemically diverse species that commonly occur in desert, steppe and montane habitats worldwide. In this study, we developed microsatellite markers to facilitate studies of genetic diversity, population structure, and gene flow in the nominal taxon of this group, Rhizoplaca melanophthalma. We characterized 10 microsatellite markers using a draft genome of R. melanophthalma s. str. assembled from Illumina reads. These loci were tested for 21 R. melanophthalma s. str. specimens and also with a subset of 18 specimens representing six additional species in the R. melanophthalma complex. The number of alleles per locus in R. melanophthalma s. str. ranged from 3 to 11 with an average of 6.7. Nei’s unbiased gene diversity ranged from 0.35 to 0.91. Amplifications of the microsatellite loci were largely successful in the other six species, although only three markers were found to be polymorphic. The new markers will provide an additional resource for studying genetic, population- and landscape-level processes in the cosmopolitan taxon Rhizoplaca melanophthalma s. str.

Lichen zonation on bedrock in accordance with the rock contours is a common phenomenon. This is also the case in the Negev Desert Highlands, where zonation along a continuum of lichens-cyanobacteria or different groups of lichens (epiliths-endoliths) within a distance of as short as <1 m can be observed. In an attempt to evaluate the factors responsible for the zonation, two plots with zonal distribution were demarcated in a north-facing slope and two at a south-facing slope, and their chlorophyll content and species composition were defined. In addition, rock properties, surface temperatures, dust input, rain amount, and the amount of non- rainfall water input, NRWI (dew, fog and high water vapor content) were measured. Whereas rock properties and aeolian input failed to explain the observed zonation, a clear temperature-induced NRWI gradient was found. The findings suggest that differential amounts of NRWI are responsible for the zonation observed, and subsequently for the clear gradient in chlorophyll content. The findings also suggest that lithobiont zonation may serve as a biomarker for subtle gradients in surface temperatures and subsequently in NRWI. Keywords Dew; Fog; Lithobionts; Temperature; water vapor; Zonation.

(2017): Adaptive differentiation coincides with local bioclimatic conditions along an elevational cline in populations of a lichen-forming fungus. - BMC Evolutionary Biology, 17:93 [14 p.].|
Background: Many fungal species occur across a variety of habitats. Particularly lichens, fungi forming symbioses with photosynthetic partners, have evolved remarkable tolerances for environmental extremes. Despite their ecological importance and ubiquity, little is known about the genetic basis of adaption in lichen populations. Here we studied patterns of genome-wide differentiation in the lichen-forming fungus Lasallia pustulata along an altitudinal gradient in the Mediterranean region. We resequenced six populations as pools and identified highly differentiated genomic regions. We then detected gene-environment correlations while controlling for shared population history and pooled sequencing bias, and performed ecophysiological experiments to assess fitness differences of individuals from different environments. Results: We detected two strongly differentiated genetic clusters linked to Mediterranean and temperate-oceanic climate, and an admixture zone, which coincided with the transition between the two bioclimates. High altitude individuals showed ecophysiological adaptations to wetter and more shaded conditions. Highly differentiated genome regions contained a number of genes associated with stress response, local environmental adaptation, and sexual reproduction. Conclusions: Taken together our results provide evidence for a complex interplay between demographic history and spatially varying selection acting on a number of key biological processes, suggesting a scenario of ecological speciation. Keywords: Adaptation Altitudinal Climate change Fungi Pool-Seq Population genomics Symbiosis SNP Gradient.

Lichen secondary metabolites can function as allelochemicals and affect the development and growth of neighboring bryophytes, fungi, vascular plants, microorganisms, and even other lichens. Lichen overgrowth on bryophytes is frequently observed in nature even though mosses grow faster than lichens, but there is still little information on the interactions between lichens and bryophytes. In the present study, we used extracts from six lichen thalli containing secondary metabolites like usnic acid, protocetraric acid, atranorin, lecanoric acid, nortistic acid, and thamnolic acid. To observe the influence of these metabolites on bryophytes, the moss Physcomitrella patens was cultivated for 5 weeks under laboratory conditions and treated with lichen extracts. Toxicity of natural mixtures of secondary metabolites was tested at three selected doses (0.001, 0.01, and 0.1 %). When the mixture contained substantial amounts of usnic acid, we observed growth inhibition of protonemata and reduced development of gametophores. Significant differences in cell lengths and widths were also noticed. Furthermore, usnic acid had a strong effect on cell division in protonemata suggesting a strong impact on the early stages of bryophyte development by allelochemicals contained in the lichen secondary metabolites. Biological activities of lichen secondary metabolites were confirmed in several studies such as antiviral, antibacterial, antitumor, antiherbivore, antioxidant, antipyretic, and analgetic action or photoprotection. This work aimed to expand the knowledge on allelopathic effects on bryophyte growth. Keywords: Allelopathy Usnic acid Bryophytes Inhibiton of growth.

In 1992-1993, I helped the late Prof. David L. Yudilevich (1930-2006) (see Mann 2006) coordinate an international symposium, “Darwin and the Beagle in Chile: Evolution Today”, at the University of Chile in Santiago, Chile (29 September-1 October 1993) as part of the ICSU General Assembly meetings held at that time in Santiago. The symposium was wide-ranging, covering the major themes of Geology, Palaeontology, Evolution & Genetics, Botany, Zoology, Ecology, Medicine & Psychology, Anthropology, History, Philosophy and Religion. To this symposium I contributed an account of Darwin’s lichens (Galloway 1993a). Although David Yudilevich later produced a fine book on Darwin in Chile (Yudilevich & Castro Le- Fort (1995), based very much on the Symposium and its associated Darwin Exhibition (to which the Linnean Society contributed a life-size copy of the Collier portrait of Darwin from the Society’s Meeting Room) which was assembled in the Patio Ignacio Domeyko of the University of Chile, none of the papers contributed to the Symposium were published, hence this account of Darwin’s lichens in a revised form in this his bicentennial year

Punctelia was proposed by Krog (1982) for some Parmelia Ach. species that have punctiform pseudocyphellae on the upper surface, and filiform or unciform conidia associated with atranorine on the upper cortex. So, Krog transferred 18 species to this new genus. Nowadays, according to literature data, Punctelia has 49 species. Twenty-four of them are reported to Brazil, representing almost 50% of the total species of the World. Nevertheless, no study has included all species and they have only been treated in Floras and there is no specific to Brazil. Due this gap in Punctelia studies and the high number of species cited to Brazil, this work had as objective to make a taxonomic and floristic study of Punctelia species with emphasis to Southern and Southeastern areas of the country. All types of the valid species (as well as their synonyms’) were requested from 39 herbaria. Almost of them were studied, totalizing 94% of the valid species. Types were described and compared with protologues and literature. Spot tests were made within the other studied specimens with potassium hydroxide (K), sodium hypochlorite (C) and p-phenylenediamine (P), and all of them were submitted in UV light for fluorescent test. Excepting on the types, Thin Layer Chromatography (TLC) with solvent C and Microcrystallization tests were made to determinate the substances. As a result the number of species increased to 74. Twenty species are new to Science: Punctelia analandiana Canêz & Marcelli, P. atrodigitata Marcelli & Canêz, P.brasiliana Canêz & Marcelli, P. dispersa Marcelli & Canêz, P. delicatula Canêz & Marcelli, P. elixii Marcelli & Canêz, P. erosa Canêz & Marcelli, P. ibiunensis Canêz & Marcelli, P. inversa Marcelli & Canêz, P. involuta Canêz & Marcelli, P. isidiata Canêz & Marcelli, P. krogiae Marcelli & Canêz, P. lobulata Canêz & Marcelli, P. marcellii Canêz, P. mirabilis Canêz & Marcelli, P. nashii Marcelli & Canêz, P. obtecta Canêz & Marcelli, P. palui Canêz & Marcelli, P. puigarii Canêz & Marcelli and P. spathulata Canêz & Marcelli.

Question: Dwarf shrub moorland dominated by ericaceous plants is a distinctive, internationally important feature of northwest Europe, with its stronghold in Scotland. There have been major declines in its condition and extent. How has moorland composition changed within Scotland over the past ca. 35 yr and what is the role of climate change, pollution and grazing in driving these changes? Location: Five hundred and forty locations across Scotland, UK. Methods: We used a long-term resurvey approach to assess change across Scottishmoorlands. We relocated plots sampled ca. 35 yr previously in alpine heath, dry heath, wet heath and bog, and recorded vegetation species composition. We assessed change in species group richness and cover and mean Ellenberg values between surveys, using paired t-tests. We used CCA with variation partitioning and regression analysis to analyse the vegetation data with spatial data sets on climate, pollution and grazing, to assess the role of each driver in driving vegetation changes. Results: Significant diversity and compositional changes between surveys were found for all habitat types, particularly alpine heath. Significant associations were found with climate (many variables), pollution (N and S) and herbivore number (primarily deer). Species richness generally increased, but several specialist species declined in cover, especially those associated with higher altitude habitats (e.g. Arctostaphylos uva-ursi, Salix herbacea and alpine lichens). Many of the most successful species are ubiquitous, e.g. the widespread grazing- and pollution- tolerant graminoids Anthoxanthum odoratum, Juncus squarrosus, Festuca rubra and Nardus stricta and the generalist mosses Rhytidiadelphus squarrosus and Hylocomium splendens. Conclusions: Diversity and composition of moorlands in Scotland have changed significantly over the ca. 35-yr period studied; the drivers of these changes are complex, with climate, pollution and grazing playing variable roles across habitats. The reduction in specialist species, homogenization of alpine heaths and declines in forb and lichen cover all represent negative changes in the biodiversity value of Scottish moorlands.

The endolichenic fungus Apiospora montagnei isolated from the lichen Cladonia sp. was cultured on solid rice medium, yielding the new diterpenoid libertellenone L (1), the new pyridine alkaloid, 23-O-acetyl-N-hydroxyapiosporamide (2) and the new xanthone derivative 8-hydroxy-3-hydroxymethyl-9-oxo-9H-xanthene-1-carboxylic acid methyl ether (3) together with 19 known compounds (4–22). The structures of the new compounds were elucidated by 1D and 2D NMR spectra as well as by HRESIMS data. The absolute configuration of the new 6,7-seco-libertellenone derivative 1 was determined by single-crystal X-ray diffraction. Four additional known compounds 23–26 were isolated when NaCl or NH4Cl were added to solid rice medium. Compounds 7–9, 18 and 26 exhibited significant cytotoxicity against the L5178 murine lymphoma cell line with IC50 values of 2.6, 0.2, 2.1, 2.7 and 1.7 μM, respectively.

The recent Great Bear Rainforest agreement recognises the high biodiversity values of this large intact area of coastal temperate rainforest by calling for old forest targets to be met by 2264. Recruiting young stands has joined conserving existing old stands as a strategy for achieving targets, but the point at which second growth stands recover oldgrowth attributes remains uncertain. We examined the recovery of epiphytes towards oldgrowth conditions by comparing community composition, richness and abundance between young (55–100 year old), mature (101–250 years old) and oldgrowth stands (>250 year old). We felled 77 western redcedar, amabilis fir, western hemlock and Sitka spruce trees, identified all epiphytes, and examined effects of stand age, region, tree species, site nutrient status and presence of residual trees on the epiphyte community. We found 229 taxa, including 49 bryophytes, 98 macrolichens and 82 crustose lichens. Epiphyte community varied by region and among tree species, but not by site productivity or presence of residual trees. In the northern region, trees in oldgrowth supported twice as many epiphyte species, seven times as many unique species, and a significantly different community composition for all functional groups (bryophytes, crustose lichens, hair lichens, cyanolichens and other macrolichens) relative to trees in stands younger than 200 years. Overall similarity between second growth and oldgrowth was about 50%. Young and mature stands overlapped considerably in richness, abundance, and community composition, indicating little recovery between 55 and 200 years. Our study suggests that in the northern region of the Great Bear Rainforest, epiphyte communities need more than 200 years to recover to oldgrowth conditions.

We studied the ten-year response of understory vegetation and lichens in mature boreal Norway spruce forests to five felling treatments in southern Finland. The stand level treatments represent a range in intensity of overstory removal: clear felling (CF) with site preparation and planting, retention felling (RF) (7% of stand volume retained) with site preparation and planting, gap felling with site preparation (GFs) (50% retained) and without planting, gap felling (GF) (50% retained) without site preparation or planting, and selection felling (SF) (67% retained) without site preparation or planting. Disc trenching was used for site preparation. Vegetation was sampled before and 1, 2, 3 and 10 years after the treatments. Both species cover and number decreased significantly immediately after all treatments. The resistance of understory vegetation, defined as the amount of change in the community structure caused by the treatments, increased in the order CF < RF < GFs < SF < GF. The dynamics of vascular plants depended on the felling intensity. The dynamics of non-vascular species depended both on the felling intensity and site preparation. CF and RF caused almost similar effects on understory vegetation composition. Local extinctions of mosses and liverworts were caused especially by CF and RF. However, even with 67% retention, 18 bryophyte species were lost during the study period. Loss of bryophyte species was higher after SF than after GF treatments, suggesting that aggregated retention is better for maintaining bryophyte species in felling areas. The resilience of understory vegetation increased in the order CF < RF < GFs < GF < SF. The abundance of mosses, liverworts and dwarf shrubs had not recovered ten years after treatments. Herb species were the most resilient compared to other species groups. We conclude that in intensively managed forest landscapes, GF and SF can be recommended as alternatives to CF to better maintain understory diversity on the stand level. However, the aim with GF and SF treatments was to further harvest the stands. Subsequent removal of the residual stands may cause substantial changes in understory vegetation for the whole treatment area. To protect late-successional bryophytes in felling areas in mesic spruce forests, high levels of retention and minimizing soil disturbance would be required. P. 24: "Forest floor lichens were not initially abundant on our sites. However, we found that the lichen richness dropped after all treatments except SF. After ten years, the lichen species richness was highest in all treatments. Similar results have been obtained by Newmaster and Bell (2002), who found several lichens colonizing mineral soils and disturbed sites five years after harvesting treatments."

• We identified four different vegetable formations in Elephant Point, Antarctica. • These formations are mainly distributed in bedrock plateaus and raised beaches. • Only 10.5% of the peninsular area is vegetated. • These formations have barely colonised the areas deglaciated since 1956. • Time passed since the deglaciation is a key factor to explain vegetable colonisation. This article focuses on the spatial distribution of vegetation formations in Elephant Point, an ice-free area of 1.16 km2 located in Livingston Island (South Shetland Islands, Antarctica). Fieldwork carried out in January 2014 consisted of floristic surveys and designation of a vegetation map. We have examined these data in a GIS environment together with topographical and geomorphological features existing in the peninsula in order to infer the factors controlling vegetation distribution. This has allowed quantifying the total area covered by the four different vegetation formations distributed across the peninsula, proliferating mainly on bedrock plateaus and Holocene raised beaches. Grass formation is essentially composed of Deschampsia antarctica, distributed almost exclusively on raised beaches, and covering 4.1% of the ice-free surface. The remaining three formations are fundamentally composed of cryptogam species. The first of which is fruticose lichen and moss formation, present on high bedrock plateaus and principally formed by lichens such as Usnea aurantiaco-atra. The next is the crustose lichen formation, spreading on bedrock plateaus near the coast populated by bird colonies. In this case, ornitocoprophilous lichens such as Caloplaca regalis, Xanthoria elegans and Haematomma erythromma are predominant. Together, both formations have colonised 5.1% of the peninsula. The last variety, moss carpet and moss cushion formation, occupies 1.4% of the deglaciated surface, spreading primarily in flooded areas, stabilised talus slopes, and bedrock plateaus as well. Therefore, the total surface colonised by vegetation is 12.2 ha, which comprises 10.5% of the peninsula. Due to the retreat of the Rotch Dome glacier, 20.1 ha remain ice-free since 1956 (17.3% of the deglaciated area). Ever since, even though the Antarctic Peninsula has registered one of the most significant temperature rises on Earth, vegetation has only colonised 0.04 ha of this new space, which merely represents 0.3% of the vegetated area in Elephant Point.

Beavers are ecosystem engineers that modify and maintain a range of special habitat types in boreal forests. They also produce large quantities of deadwood that provide substrate for many lignicolous organisms such as calicioid fungi (Ascomycota). We studied how calicioid diversity differed between boreal riparian forests with and without beaver activity. The results show that calicioid diversity were significantly higher at beaver sites compared to the other two forest site types studied. The large quantity and diverse forms of deadwood produced by beavers clearly promotes calicioid diversity in the boreal landscape. The specific lighting and humidity conditions within beaver wetlands could be the reason why they promote the success of certain calicioid species.
