Lichens are extremophilic organisms surviving in extremely low temperature and dehydration; however, the molecular mechanism of frost and dehydration resistance is not yet fully understood. Low temperature behavior of Cetraria aculeata thalli at the hydration level between ∆m/m0 = 0.039 and ∆m/m0 = 0.964, defined as a ratio of mass of water adsorbed to the thalli, ∆m, to dry mass of the thalli, m0, and interpreted as water content, %WC, in a fractional form (∆m/m0 = %WC/100) was investigated using nuclear magnetic resonance (NMR) and differential scanning calorimetry (DSC). Proton free induction decays were decomposed into components: coming from solid matrix of thallus and exponentially decaying from loosely bound and from tightly bound water. At low hydration levels the loosely bound water fraction (cooperatively freezing water) is detected down to − 15.6 °C. With the decreasing temperature loosely bound water fraction is gradually transferred to the tightly bound water pool (non-freezing water) which could play significant role in freezing resistance mechanism. At higher hydration levels DSC scans show the presence of cooperative water freezing in thallus. The lowest hydration level at which the cooperative freezing of water bound in C. aculeata thallus is detected by DSC is equal to 0.453. DSC courses recorded after 120 min incubation of C. aculeata thallus in − 20 °C suggest the lowest hydration level in which ice formation could be observed is decreased to 0.167, as a result of water molecule diffusion to places where ice microcrystallites were formed. Supercooled water behavior in C. aculeata thalli reveals a composed behavior. Two processes take place: supercooled liquid water mobility gradually decrease with the decreased temperature and the diffusion of supercooled water molecules to ice microcrystallites and, thus the solid phase growth.

While higher plant communities found on ultramafics are known to display peculiar characteristics, the distinguishability of any peculiarity in lichen communities is still a matter of contention. Other biotic or abiotic factors, rather than substrate chemistry, may contribute to differences in species composition reported for lichens on adjacent ultramafic and non-ultramafic areas. This work examines the lichen biota of ultramafics, at global and regional scales, with reference to species-specific functional traits. An updated world list of lichens on ultramafic substrates was analyzed to verify potential relationships between diversity and functional traits of lichens in different Köppen–Geiger climate zones. Moreover, a survey of diversity and functional traits in saxicolous communities on ultramafic and non-ultramafic substrates was conducted in Valle d’Aosta (North-West Italy) to verify whether a relationship can be detected between substrate and functional traits that cannot be explained by other environmental factors related to altitude. Analyses (unweighted pair group mean average clustering, canonical correspondence analysis, similarity-difference-replacement simplex approach) of global lichen diversity on ultramafic substrates (2314 reports of 881 taxa from 43 areas) displayed a zonal species distribution in different climate zones rather than an azonal distribution driven by the shared substrate. Accordingly, variations in the frequency of functional attributes reflected reported adaptations to the climate conditions of the different geographic areas. At the regional scale, higher similarity and lower species replacement were detected at each altitude, independent from the substrate, suggesting that altitude-related climate factors prevail over putative substrate–factors in driving community assemblages. In conclusion, data do not reveal peculiarities in lichen diversity or the frequency of functional traits in ultramafic areas.

Predictors of cryptogamic wood-inhabiting communities need to be examined to understand the drivers of forest biodiversity. We estimated the influence of bark cover on the wood-inhabiting vegetation on conifer logs in early stages of epixylic succession in mature European boreal and hemi-boreal forests. Abundance of substrate groups with respect to log attributes was estimated with generalized linear and generalized linear mixed models. The structure and composition of epixylic communities was analysed using non-metric multidimensional scaling with subsequent environmental fitting. The abundance of true epixylics was inversely related to bark cover. In the first stage, bark cover did not influence the abundance of epiphytes and epigeous species; positively influenced the abundance of facultative epixylics on spruce logs and negatively influenced it on pine logs. In the second stage, the effect of bark cover was positive for epiphytes and epigeous species on spruce logs and for facultative epixylics independent of log species identity and negative for epigeous species on pine logs. Generalist species did not depend on bark cover. Total cover of wood-inhabiting vegetation was marginally influenced by bark cover. The effect of bark cover on epixylic vegetation at community level was negligible. In general, bark cover favours the establishment and growth of species with low substrate specificity. This preference may lead to either burial of logs by epigeous bryophytes, or facilitation of succession towards the dominance of ground vegetation.

Directly observed biodiversity data have a limited temporal span of c. 100– 150 years. Consequently, for a region such as temperate Western Europe, our knowledge of species distributions is restricted to a period impacted by the process of massive industrialisation. There is a danger of shifted baselines in terms of conservation policy and targets. Here we present a novel source of high resolution archaeobotanical information for lichen epiphyte bioindicators; these data can reconstruct species distributions for the pre-industrial European landscape. We compare these historic records to a species’ postindustrial distribution and environmental response, quantifying the spatial trend and causes of biodiversity loss. The results indicate regional extinction rates of c. 76% in response to habitat loss and industrial pollution. We propose pre-industrial baselines that would better represent biodiversity restoration for temperate regions (net gain), and which would be equitable with advocacy for species and habitat protection in the present-day tropics (no net loss).

The relation between water status and expression profiles of desiccation -related genes has been studied in the desiccation tolerant (DT) aeroterrestrial green microalga Trebouxia gelatinosa, a common lichen photobiont. Algal colonies were desiccated in controlled conditions and during desiccation water content (WC) and water potential (Ψ) were measured to find the turgor loss point (Ψtlp). Quantitative real-time PCR was performed to measure the expression of ten genes related to photosynthesis, antioxidant defense, expansins, heat shock proteins (HSPs), and desiccation related proteins in algal colonies collected during desiccation when still at full turgor (WC > 6 g H2O g−1 dry weight), immediately before and after Ψtlp (−4 MPa; WC ∼ 1 g H2O g−1 dry weight) and before and after complete desiccation (WC < 0.01 g H2O g−1 dry weight), quantifying the HSP70 protein levels by immunodetection. Our analysis showed that the expression of eight out of ten genes changed immediately before and after Ψtlp. Interestingly, the expression of five out of ten genes changed also before complete desiccation, i.e. between 0.2 and 0.01 g H2O g−1 dry weight. However, the HSP70 protein levels were not affected by changes in water status. The study provides new evidences of the link between the loss of turgor and the expression of genes related to the desiccation tolerance of T. gelatinosa, suggesting the former as a signal triggering inducible mechanisms.

This paper presents the environmental radiation risk assessment based on two software program approaches ERICA Tool (version 1.2) and RESRAD BIOTA (version 1.5) to estimate dose rates to terrestrial biota in the area around the largest coal fired power plant in Serbia. For dose rate assessment software's default reference animals and plants and the best estimated values of activity concentrations of 238U, 234U, 234Th, 232Th, 230Th, 226Ra, 210Pb, 210Po, 137Cs in soil were used. Both approaches revealed the highest contribution to the internal dose rate due to 226Ra and 210Po, while 137Cs contributed the most to the external dose rate. In the investigated area total dose rate to biota derived using ERICA Tool ranged from 0.3 to 14.4 μGy h−1. The natural radionuclides exhibited significantly higher contribution to the total dose rate than the artificial one. In the investigated area, only dose rate for lichens and bryophytes exceeded ERICA Tool screening value of total dose rate of 10 μGy h−1 suggested as confident that environmental risks are negligible. The assessed total dose rates for reference animals and plants using RESRAD BIOTA were found to be 7 and 3 μGy h−1, respectively. In RESRAD BIOTA - Level 3, 10 species (Lumbricus terrestris, Rana lessonae, Sciurus vulgaris, Anas platyrhynchos, Lepus europaeus, Vulpes vulpes, Capreolus capreolus, Suss crofa, Quercu srobur, Tilia spp.) representative for the study area were modeled. Among them the highest total dose rate (4.5 μGy h−1) was obtained for large mammals. Differences in the predicted dose rates to biota using the two software programs are the consequence of the difference in the values of transfer parameters used to calculate activity concentrations in biota. Doses of ionizing radiation estimated in this study will not exhibit deterministic effects at the population level. Thus, the obtained results indicate no significant radiation impact of coal fired power plant operation on terrestrial biota. This paper confirms the use ERICA Tool and RESRAD BIOTA softwares as flexible and effective means of radiation impact assessment.

(2018): Dating late Holocene lava flows in Pico de Orizaba (Mexico) by means of in situ-produced cosmogenic 36Cl, lichenometry and dendrochronology. - Quaternary Geochronology, 47: 93–106.|
The knowledge of the eruptive history of volcanic centers allows for improving the evaluation of the related risks and hazards in populated areas, but substantially depends on the ability of dating the lava flows. However, traditional methods such as U-Th/He, 40Ar-39Ar, 40K-40Ar and radiocarbon dating are not always suitable. Therefore, an alternative approach based on the combination of in situ-produced 36Cl based cosmic ray exposure dating, lichenometry and dendrochronology was tested on two lava flows (called Lava flow “A” and “B”) from Pico de Orizaba (Mexico), previously attributed to 16th and 17th century eruptions, respectively. The presented results show that both lava flows are significantly older than their assumed 16th and 17th century ages. Regarding lava flow “A”, the measured in situ-produced 36Cl concentrations lead to a mean age of 3.03 ± 0.70 ka, while dendrochronology and lichenometry yield minimum ages of 834 and 1130 years, respectively. Regarding lava flow “B”, the measured in situ-produced 36Cl concentrations lead to a mean age of 1.45 ± 0.35 ka, whereas lichenometry gives a minimum age of ∼1000 years. Overall, this demonstrates that the combination of in situ-produced 36Cl based cosmic ray exposure dating, lichenometry and dendrochronology has a considerable potential for dating purposes on young deposits and landforms, in particular on lava flows at high elevation sites.

(2018): Exclusion of small mammals and lagomorphs invasion interact with human-trampling to drive changes in topsoil microbial community structure and function in semiarid Chile. - Soil Biology and Biochemistry, 124: 1–10.|
Species losses and additions can disrupt the relationship between resident species and the structure and functioning of ecosystems. Persistent human-trampling, on the other hand, can have similar effects through the disruption of biocrusts on surface soils of semiarid systems, affecting soil stability and fixation of carbon and nitrogen. Here, we tested the interactive and synergistic impacts of the exclusion of native mammalian herbivores and the effects of introduced lagomorphs in a semiarid thorn scrub ecosystem, where soils were subjected to two different trampling intensities (i.e., trampled and non-trampled). We postulated that because of their differential habitat use and fossorial activities, with respect to native small mammals, lagomorphs would have strong negative effects on soil structure, biocrust cover, and biocrust bacterial community structure. Our expectations were that changes in biocrust cover in response to trampling where native mammals were excluded, but exotic lagomorphs were present, will spread their impacts on soil chemical and physical features. To test our hypotheses, we measured changes in soil biogeochemical properties in four experimental plots where lagomorphs (L)/small mammals (SM) were experimentally manipulated to exclude them from the plots (−), or let them be present (+). The experimental combinations monitored were: -L/+SM, -L/-SM, +L/+SM, and +L/-SM. Results showed that human-trampling disturbance interacted with the loss of native small mammals and the presence of non-native lagomorphs to cause large changes on biological (i.e., biocrust cover, bacterial and nifH genes abundance), physical (i.e., soil moisture and soil stability) and chemical (i.e., TC and TN) soil features. The relative impacts of trampling disturbance on biological and physicochemical features were strongly influenced by the presence of non-native lagomorphs. For example, larger decreases in biocrust cover and bacterial abundance were observed in treatments without lagomorphs (-L/+SM; -L/-SM). In turn, losses of biocrust cover, in addition to trampling, determined decreases in soil stability in all treatments. These results suggest that non-native lagomorphs surpass the effects of the loss of native small mammals in reducing soil quality and productivity. Therefore, human-trampling has the potential to convert low disturbed soils, as those observed in non-trampled soils in treatments -L/+SM, -L/-SM into poor soils with low biocrusts cover and concomitant low stability, as observed in +L/+SM; +L/-SM treatments. These findings agree with previous observations that different components of global change act in synergic ways in fragile, water-limited environments. Because biological invasions and soil surface disturbance are becoming widespread in dryland regions globally, understanding the long-term consequences of these interactions is essential.

Biocrusts are a critical biological community that represents one of the most important photosynthetic biomass pools in dryland regions. Thus, they play an important role in CO2 fluxes in these regions, where water availability limits vascular plant growth and development. The effect of biocrusts on CO2 fluxes was expected to be controlled by the interplay of several environmental factors, as well as biocrust developmental stage and coverage. To test this hypothesis, we performed an in situ study during which we measured net CO2 fluxes and dark respiration over biocrusted soils at different successional stages in two semiarid ecosystems, where biocrusts are one of the main surface components. In addition, CO2 flux was measured in annual plants, which were an abundant interplant cover in one of the study sites during the measurement period. Field campaigns were conducted from early morning to dusk on selected days with different environmental conditions over the year. Gross photosynthesis was calculated from net CO2 flux and dark respiration. Biocrusts showed contrasting responses in CO2 exchange depending on environmental conditions during the day and the year and depending on biocrust developmental stage. CO2 flux in biocrusts was highly correlated with soil moisture, but also with photosynthetically active radiation and temperature. During dry soil periods, soils colonized by biocrusts had net CO2 fluxes close to zero, but after precipitation events (light or heavy) all the biocrust types began to photosynthesize. When the rainfall was right after an extended drought, the respiration by biocrusts themselves and underlying soil exceeded the biocrust gross photosynthesis, and consequently soils colonized by biocrusts behaved as CO2 sources. On the contrary, consecutive precipitation events and mild temperatures caused soil colonization by biocrusts to behave as CO2 sinks. Annual plants were measured during their senescence and acted as CO2 sources during all measurement campaigns. The time of day when the biocrusts showed net CO2 fixation depended on the interplay of humidity just above them, air temperature and photosynthetically active radiation. The biocrust type also significantly influenced CO2 fluxes in both semiarid ecosystems. In general, during wet periods, late successional biocrusts (i.e. lichens and mosses) had higher gross photosynthesis than early successional biocrusts (developed and incipient cyanobacteria crusts). Nevertheless, dark respiration from late successional biocrusts and underlying soils was also higher than from early successional biocrusts, so both biocrust types had similar net CO2 fluxes. These results highlight the importance of considering the whole soil profile under biocrusts with their associated microbial communities as well as the temporal variability of CO2 fluxes in soils covered by biocrusts in carbon balance studies in semiarid regions.

Salinity, water scarcity in the summer season, and grazing pressure are major problems in semi-arid ecosystems in the south-east region of the Caspian Sea where the Alagol rangelands of Turkmen Sahra (Golestan province) of North East Iran suffer from over-grazing and soil loss. This study investigated the influence of biological soil crusts (biocrusts) on soil physicochemical properties. Biocrusts create complex communities of specialized organisms composed of cyanobacteria, algae, microfungi, lichens, mosses and other microorganisms. Results have shown that bioencrusted soils increased levels of organic carbon, nitrogen, phosphorus, copper, and iron, and reduced pH, calcium carbonate, sodium, calcium, magnesium, sodium adsorption ratio and exchangeable sodium percentages compared to soils without biocrusts. Other positive influences of biocrusts on soil properties included increased infiltration (0.16 v. 0.081 cm min−1 for steady state rates), available water content, mean weight diameter of soil aggregates, geometric mean diameter and water stable aggregates. Bulk density was reduced under bioencrusted soils relative to non-biocrusts soils. In general, biocrusts had a positive effect on many soil properties and thus enhanced soil quality. Keywords: Alagol rangelands; Biocrusts; Lichens; Inﬁltration; Salinity; Turkmen Sahra.

(2018): Oligocene origin and drivers of diversiﬁcation in the genus Sticta (Lobariaceae, Ascomycota). - Molecular Phylogenetics and Evolution, 126: 58–73.|
A major challenge to evolutionary biologists is to understand how biodiversity is distributed through space and time and across the tree of life. Diversification of organisms is influenced by many factors that act at different times and geographic locations but it is still not clear which have a significant impact and how drivers interact. To study diversification, we chose the lichen genus Sticta, by sampling through most of the global range and producing a time tree. We estimate that Sticta originated about 30 million years ago, but biogoegraphic analysis was unclear in estimating the origin of the genus. Furthermore, we investigated the effect of dispersal ability finding that Sticta has a high dispersal rate, as collections from Hawaii showed that divergent lineages colonized the islands at least four times. Symbiont interactions were investigated using BiSSE to understand if green-algal or cyanobacterial symbiont interactions influenced diversification, only to find that the positive results were driven almost completely by Type I error. On the other hand, another BiSSE analysis found that an association with Andean tectonic activity increases the speciation rate of species.

The subject of conifer regeneration failure after canopy removing disturbance leading to expansion of ericaceous heaths in boreal forests received considerable attention. However, despite seedbed quality being a key factor in tree regeneration, our understanding of the role of lichen and moss dominated seedbeds on tree seedling regeneration after forest fires remains unclear. Objective of this study was to investigate the effect of time since fire and post-fire cryptogamic (lichen and moss) seedbeds with variable organic matter thickness on black spruce regeneration. We conducted black spruce seeding experiment in black spruce – Kalmia forests burned 11, 17 and 37 years ago. In each site we applied three seedbed manipulation treatments (mat-intact, mat-mixed and mat-removed) to test if seedbed manipulation improves spruce regeneration. This experiment was extended to three moss-dominated seedbeds to compare seedbed moisture and temperature effects on spruce regeneration. We also tested potential allelopathic effect of two common lichen and moss species in laboratory bioassay. Seed regeneration was low in all seedbeds. Black spruce germination and seedling growth was lowest in presence of Cladonia cristatella followed by C. stellaris, Polytrichum juniperinnum and Pleurozium schriberi. HPLC analysis of C. cristatella indicated the presence of usnic acid, a common germination inhibiting allelochemical. Moss seedbeds were relatively favourable for spruce regeneration. We conclude that (i) lichen seedbeds inhibit seedling regeneration due to adverse biophysical and chemical (allelopathic) effects, (ii) moss seedbeds facilitate black spruce regeneration by maintaining favourable moisture and temperature, and (iii) seedbed manipulation treatments produce mixed results depending on the dominant cryptogam, organic matter thickness and seedbed moisture and temperature.

Biological soil crusts (biocrusts) are composed of a combination of cyanobacteria, green algae, lichens, and mosses that can protect arid soil surfaces from erosive forces. The presence of biocrusts in desert regions is influenced by a complex interaction of climatic, edaphic, and topographic variables, but their distribution and coverage densities in southern California deserts are not precisely mapped. Visible satellite bands (red-green-blue; RGB) and infra-red image resolution are generally too coarse to distinguish between biocrusts and their interstitial sand substrates, limiting most remote sensing analysis of these soil biotic assemblages. The purpose of this study was to better understand the relationships between biocrust cover, surface coloration and roughness, and the thermal infra-red (TIR) emission properties of biocrusts to determine if new types of imaging of desert surfaces could be used to more accurately detect biocrust presence. Based on the results from megapixel digital photos and TIR imaging for nearly 130 different, well-developed biocrust surfaces in the Mojave and Lower Colorado Deserts of California, we designed laboratory heating experiments to test the effect of biocrust cover on the heating properties of sandy wash habitats. Biocrust samples collected from the field were subjected to artificial heating and cooling to simulate the Mojave Desert diurnal cycle. We used image segmentation algorithms to separate true-color biocrust images from their sandy substrates, and to map the heating and cooling patterns of these surfaces with different levels of biocrust coloration and roughness. The major findings of this study showed that biocrust patch images in the field had Red texture mean values between digital numbers of 95 and 131 with moderate positive tail shewness levels, indicative of a highly rugose surface of the biocrust cover. Such patches were also well-compacted overall, with moderate skewness toward negative tails. In controlled laboratory temperature experiments to simulate the desert diurnal cycle, surface wetting with a fine mist of water resulted in significantly lower peak surface temperatures of biocrust samples compared to dry biocrust heating results of the same crust and sand samples. The findings of this study can improve future mapping for lichen-dominated biocrust surfaces in the Mojave Desert.

The present study provides a brief survey of the genus Parmelina in the Russian Caucasus (Western Transcaucasia, Western, Central and Eastern Caucasus) with a special emphasis on species distribution. The study area is located in the largest nature reserves of the Russian Caucasus — Kavkazskiy, Utrish, Severo-Osetinskiy, Erzi. This paper contributes to a better understanding of the genus in the Caucasus, focusing mainly on the author’s collections in different regions of the Northern Caucasus in 2008–2016. Four species have been identiﬁed from the Russian Caucasus — Parmelina carporrhizans, P. pastillifera, P. quercina and P. tiliacea. Notes on their morphology, anatomy, ecology and distribution are based on data obtained from a study of ca. 20 specimens of each species. The presence of whitish macules on the upper surface of P. carporrhizans (after Clerc, Truong, 2008) as an important diagnostic feature was shown. The Caucasian material shows the differences in size and proportions of ascospores, size and shape of pycnoconidia between critical species P. carporrhizans and P. quercina. An identiﬁcation key for Caucasian Parmelina species is composed for the ﬁrst time and can be used for central regions of Russia. Keywords: lichens, genus Parmelina, taxonomic review, key to species, Caucasus, nature reserves, Russia.

The objective of the study was to conduct a thorough anatomical, morphological and taxonomic study of the species of the lichen genus Peltula from Baikal Siberia belonging to the group with peltate-umbilicate sorediate thallus (euplocabolanderi-type). Until now, among over 40 Peltula species, only four ones belonged to this group (P. africana, P. bolanderi, P. euploca and P. farinosa). In addition to the widespread species P. euploca, two new species have been identiﬁ ed, essentially different from all the four previously known members of the group, primarily by the expressed polyphyllous character of the thallus. Descriptions of the new species, P. pannarioides and P. rosulata, with their macro and micro photos and a map of their distribution, are provided. P. pannarioides is characterized by a thick polyphyllous thallus, upturned undulate sorediate margins of lobes, brown-grey reticulate-grained pruinose upper surface, large granulose soredia, thick cracked epinecral layer, and medulla composed of densely interwoven periclinally oriented hyphae. P. rosulata is characterized by thin polyphyllous thallus, upturned undulate sorediate margins of lobes, dark-brown, smooth, matte upper surface, large granulose soredia, thin continuous brownish epinecral layer, and medulla composed of loosely interwoven periclinally and anticlinally oriented hyphae. The territory of Baikal Siberia and of Southern Siberia as a whole may be regarded as one of the centers of the species diversity of genus Peltula, namely of the group of species with polyphyllous umbilicate sorediate thallus. The entire complex of the species with the euploca-bolanderi-type thallus requires more detailed study. Keywords: lichens, Peltula, new species, peltate-umbilicate, polyphyllous, sorediate, Russia.

The diversity of lichens and allied fungi of the Oranienbaumsky (Rambovsky) Prospective Protected Area (St. Petersburg, Russia) has been studied for the ﬁ rst time. Among 214 discovered species 199 are lichens, 11 are lichenicolous fungi and 4 are saprobic fungi traditionally reported in lichenological lists. The lichen diversity of the territory is estimated as one of the richest within the limits of St. Petersburg. The lichen Protothelenella petri is recorded for the ﬁ rst time for Russia, the lichens Biatora cuprea, Brianaria bauschiana, Micarea leprosula and Thelocarpon lichenicola are new for the North-Western European Russia, lichens Aspicilia laevata and Trapelia glebulosa, as well as the lichenicolous fungi Stigmidium fuscatae and Syzygospora physciacearum are new for St. Petersburg, the lichenicolous fungus Sphaerellothecium coniodes was not earlier known either from St. Petersburg or Leningrad Region. Nine species included in the Red Data Book of St. Petersburg are known from the Oranienbaumsky Prospective Protected Area. Of these, Ramalina sinensis has not been reported from the administrative territory since 1938 and is probably extinct from the historical localities. Parmelia fraudans was found in St. Petersburg for the ﬁ rst time in 80 years and we propose to include this species into the Red Data Book.

A molecular phylogenetic analysis based on the DNA barcode marker (nrITS) of 12 specimens of Lecidea leucothallina revealed three monophyletic clades, two apotheciate and one sorediate. The sorediate clade is described as L. toensbergii, and the two apotheciate clades are regarded as representing two cryptic species within L. leucothallina. Pannarin may be present or absent in the upper cortex in all three clades, and should not be used as a diagnostic character for further separation of taxa in this group.

Field studies in Alaska, Oregon, and Washington revealed unusual morphotypes that appeared similar to U. torrefacta in many ways, but differed in their tough, multilayered growth form. DNA sequencing and thin-layer chromatography confirmed our suspicion that these do not belong with U. torrefacta. Two new species are described, Umbilicaria dura and U. multistrata.

Crustose lichens and lichenicolous fungi growing on decaying wood were examined from 13 study areas in Finland. Epigloea urosperma is reported as new to Finland and Lecania furfuracea as new to Fennoscandia. In addition, the taxonomy and habitat requirements of six Micarea species are discussed. The species were recently added to the checklist of Finnish lichens based on collections included in this work.

Re-investigation of a collection from Germany in herbarium FR, originally identified as Moelleropsis nebulosa, showed that it in fact represents Vahliella atlantica. The morphology and anatomy of the two species are compared and hitherto unknown pycnidia of V. atlantica described. The additional record constitutes a considerable expansion of range and ecological niche for a species that was formerly only known from Macaronesia and oceanic parts of Europe. An intensive search at the collecting site, in order to find material suitable for DNA isolation, showed that the species has apparently disappeared from the locality.

Sites of Lobaria pulmonaria reported from the nemoral zone of the Swedish provinces Skåne and Blekinge since 1990 were revisited. At each locality, the habitat ecology and lichen viability were investigated. A substantial decline was noted, particularly in Skåne, as L. pulmonaria was found at only 24 sites, 22 of which were forests and two were wooded meadows. The commonest habitats for L. pulmonaria were Tilio-Acerion forests and species-poor, oligotrophic beech forests, and the commonest substrates were trunks of Acer platanoides and Fagus sylvatica, followed by Quercus robur. The inhabited trees grew often in the upper part of steep slopes or rock faces, either on rocky or boulder-rich, meso- to oligotrophic soils. Lobaria pulmonaria showed a preference for locally cool climates. It had survived at sites offering a stable environment in terms of light, moisture and temperature, with minor influence of air pollution, agriculture and forestry practices.

Sticta torii Simon & Goward sp. nov. is an isidiate lichen on Alnus, Malus and Picea branches in hypermaritime regions of northwestern North America. It is a rare species, currently known from only a few localities along a narrow longitudinal range in Southeast Alaska, British Columbia and Oregon. It differs from S. fuliginosa and S. sylvatica in its smaller, more irregular lobes and generally well-developed fringe of marginal isidia, and from S. beauvoisii in its smaller size, less elongate lobes and distinctly arbuscular to penicillate marginal isidia. Also diagnostic are the cyphellae, the basal portions of which bear cells with numerous papillae – a feature shared with a small group of closely allied neotropical species including the recently described S. arbuscula and S. arbusculotomentosa. These latter species, however, bear tomentum over the upper surface, unlike S. torii, which is glabrous.

The course Cryptogams and Nature Conservation at the Swedish University of Agricultural Sciences, Uppsala, Sweden had its closing meeting at the field station Christiansminde in Sorø, Sjælland, Denmark in the years 2014–2017. In 2017, G. Thor also visited Jylland. Several lichens and lichenicolous fungi were collected during these excursions. Eleven species are new to Denmark, Bacidina neosquamulosa, Briancoppinsia cytospora, Homostegia piggotii, Hyperphyscia adglutinata, Lichenochora obscuroides, Micarea viridileprosa, Monodictys epilepraria, Phaeocalicium praecedens, Psilolechia leprosa, Ramonia interjecta and Vezdaea leprosa. Eight additional species are new to Sjælland, Arthonia ligniariella, Bacidina adastra, Bryostigma muscigenum, Candelariella efflorescens, Hypotrachyna revoluta, Lecanora compallens, Micarea micrococca and Phaeocalicium populneum. The visited localities are briefly described.
|29292||Thell A., Kärnefelt I. & Seaward M.R.D. (2018): Splitting or synonymizing – genus concept and taxonomy exemplified by the Parmeliaceae in the Nordic region. - Graphis Scripta, 30(6): 130–137.|
The current use of a 30 million year dateline for accepting genera in the Parmeliaceae is evaluated. Its value is doubtful since evolution obviously went quicker in some lichen groups compared with others. Parallel evolution is also very common among lichens. Polyphyletic genera should always be split, while sister groups may remain split or be combined after considering non-molecular characters. Researchers dealing with the same groups should consult each other in an endeavour to achieve consensus. The most recent changes in taxonomy in the Nordic Parmeliaceae relate to the cetrarioid group, the last large clade to be revised. The division into two large genera, Cetraria and Nephromopsis, is supported, with a recommendation to retain Masonhalea due to its unique non-molecular characters. Three cases of parallel evolution in Cetraria and Nephromopsis are illustrated. Synonymization of Gowardia with Alectoria is supported, whereas synonymization of the parasitic genera Raesaenenia and Nesolechia with Protousnea and Punctelia respectively seems hardly necessary. Segregation of Montanelia from Melanelia is strongly supported, in contrast to the morphologically similar sister groups of Usnea, Dolochousnea and Eumitria, being recognised as separate genera.

The new species Lecidella varangrica Haugan & Tønsberg is described from the northern shores of the Varanger Peninsula, Finnmark, Norway. It probably belongs to the saxicolous L. asema group by having a pigmented hypothecium and by producing chloroxanthones. Lecidella varangrica is distinguishable from other species in this group by a set of characters: the presence of soralia, the small apothecia with rather small ascospores, and the production of aotearone as the major chemical constituent. Lecidella varangrica is a species of vertical to overhanging weather-protected rock faces with strong marine influence along the harsh shores of the Barents Sea.

Toninia tecta, a non-lichenized obligately lichenicolous fungus, is described new to science. The species is known from several sites in midcontinental North America. Toninia tecta has an endokapylic thallus with dark superficial apothecia restricted to the sheltered undersides of thalli of saxicolous umbilicate species of Dermatocarpon. The new species is characterized by 3-septate ellipsoid ascospores, elongate filiform conidiospores, a reddish brown hypothecium and grey to greenish epithecium that reacts KOH–, HNO3þ violet. Features of the species are compared with those of other lichenicolous taxa in the genus. Keywords: Lichenicolous fungi, central North American grasslands.

Dryland ecosystems cover over 41% of the earth's land surface, and living within these important ecosystems are approximately 2 billion people, a large proportion of whom are subsistence agropastoralists. Improper grazing in drylands can negatively impact ecosystem productivity, soil conservation, hydrologic processes, downstream water quantity and quality, and ultimately human health and economic well-being. Concerns regarding the degraded state of western US rangelands in the 1950s resulted in an interagency committee to study the effects of land use on runoff and erosion processes. In 1953, a federal research group established four paired watersheds in western Colorado to study the interaction of grazing by domestic livestock, runoff, and sediment yield. Exclusion of livestock from half of the watersheds dramatically reduced runoff and sediment yield after the first 10 yr—primarily due to changes in ground cover but not vegetation. Here, we report results of repeated soils and vegetation assessments of the experimental watersheds after more than 50 yr of grazing exclusion. Results show that many of the differences in soil conditions between grazed and ungrazed watersheds observed in the 1950s and 1960s were still present in 2004, despite reduced numbers of livestock: few differences in vegetation cover but large differences in biological soil crusts, soil stability, soil compaction, and soil biogeochemistry. There were differences among soil types in response to grazing history, especially soil lichen cover and soil organic matter, nitrogen, and sodium. Comparisons of ground cover measured in 2004 with those measured in 1953, 1966, and 1972 suggest much of the differences between grazed and ungrazed watersheds likely were driven by high sheep numbers during droughts in the 1950s. Persistence of these differences, despite large reductions in stocking rates, suggest the combination of overgrazing and drought may have pushed these salt desert ecosystems into a persistent, degraded ecological state. Key words: erosion; lichens; livestock; Mancos Shale; salt desert; state change.

47 lichen species of 21 genera and 7 families are determined in the town of Gomel. Some features of their distribution in Gomel were studied. No correlation has been found between the number of lichen species on a tree and its trunk diameter. Different tree species were found to have different sets of lichen species. Bark pH values were defined for 11 tree species in Gomel. Three groups of tree species have been distinguished by bark pH. The first group includes Acer negundo with the bark pH = 7.17, Populus balsamifera — 6.66, and P. nigra — 6.63; the second one: Acer platanoides — pH = 6.12, Fraxinus excelsior — 5.77, Tilia cordata — 5.53; the third: Aesculus hippocastanum — pH = 4.95, Betula pubescens — 4.89, B. pendula — 4.88, Quercus robur — 4.79, Acer saccharinum — 4.74. Certain species of lichens are confined to these groups: Physconia sp. colonizes trees of the first group (pH 6.0-8.0); Hypogymnia physodes, Evernia prunastri, Melanohalea exasperatula grow on trees of the third group (pH 4.0-5.5); trees of the second group (pH 4.5-6.5) provide a suitable substrate for the most lichen species.

The particularities of the lichen coefficient LC (the ratio of lichens to vascular plants, or L : P-ratio) in different geographical regions of the Earth and different areas of Russia are determined on the basis of analysis of numerous quantitative estimations of lichen and vascular plant diversity. High values of LC in Arctic regions are caused by adverse conditions for growth of the vascular plants, while low LC values in plain regions with arid climate are caused by adverse influence of bioclimatic conditions on development of lichen flora. The mountains in temperate latitudes (especially near oceans) and tropics are optimal for forming rich and diverse lichen floras. Data on LC in different nature zones can be used for estimation of lichen species diversity, and to indicate some gaps in researches of regional lichen floras. Keywords: lichens, vascular plants, species diversity, ratio data, lichen coefficient.

Large areas of formerly oak-dominated woodlands are currently managed for timber prod- ucts, and if they are used in a conservation-oriented way, they are often abandoned and left to become wilderness. We focused on the situation when an oak woodland is still partly managed as an ancient game park and partly abandoned as a nature conservation amend- ment. We studied this effect using a multi-taxa approach with lichens, fungi and beetles and investigated their response to the changing patterns in canopy openness, dead wood distribution and host tree conditions. The study was done in the Hradec Králové region of the Czech Republic. We found that the maintenance of canopy openness, as determined by management, was the primary driver influencing species composition. Canopy closure led to homogenization of the beetle and lichen communities and the loss of species. Fungi were mainly driven by the amount of dead wood, and abandonment favored their species richness. The creation of a new wilderness was only profitable for fungi, and the mainte- nance of canopy openness was an important driver for most of the studied taxa (i.e., biodi- versity maintenance). Canopy openness and the presence of veteran trees could be used as an indicator of a management history that helps conserve biodiversity. Appropriate condi- tions for all taxa studied could be fulfilled using wood pasturing or game keeping in combi- nation with dead tree retention.

Elevated atmospheric nitrogen (N) deposition is a major driver of change, altering the structure/functioning of nutrient-poor Calluna vulgaris-heathlands over Europe. These effects amply proven for north-western/central heathlands may, however, vary across the ecosystem's distribution, especially at the range limits, as heathlands are highly vulnerable to land-use changes combined with present climate change. This is an often overlooked and greatly understudied aspect of the ecology of heathlands facing global change. We investigated the effects of five N-fertilisation treatments simulating a range of N deposition rates (0, 10, 20, and 50 kg N ha−1 yr−1 for 1 year; and 56 kg N ha−1 yr−1 for 9 years) on the Calluna-plants, the plant functional groups, species composition and richness of two life-cycle stages (building/young- and mature-phase) of Calluna-heathlands at their rear-edge limit. Our findings revealed a dose-related response of the shoot length and number of flowers of young and mature Calluna-plants to the addition of N, adhering to the findings from other heathland locations. However, cumulative high-N loading reduced the annual growth and flowering of young plants, showing early signs of N saturation. The different plant functional groups showed contrasting responses to the cumulative addition of N: annual/perennial forbs and annual graminoids increased with quite low values; perennial graminoids were rather abundant in young heathlands but only slightly augmented in mature ones; while bryophytes and lichens strongly declined at the two heathland life-cycle stages. Meanwhile there were no significant N-driven changes in plant species composition and richness. Our results demonstrated that Calluna-heathlands at their low-latitude distribution limit are moderately resistant to cumulative high-N loading. As north-western/central European heathlands under high-N inputs broadly experienced the loss of plant diversity and pronounced changes in plant species dominance, rear-edge locations may be of critical importance to unravel the mechanisms of heathland resilience to future global change.

Although a broad diversity of eukaryotic and bacterial taxa reside on rock surfaces where they can influence the weathering of rocks and minerals, these communities and their contributions to mineral weathering remain poorly resolved. To build a more comprehensive understanding of the diversity, ecology and potential functional attributes of microbial communities living on rock, we sampled 149 tombstones across three continents and analysed their bacterial and eukaryotic communities via marker gene and shotgun metagenomic sequencing. We found that geographic location and climate were important factors structuring the composition of these communities. Moreover, the tombstone‐associated microbial communities varied as a function of rock type, with granite and limestone tombstones from the same cemeteries harbouring taxonomically distinct microbial communities. The granite and limestone‐associated communities also had distinct functional attributes, with granite‐associated bacteria having more genes linked to acid tolerance and chemotaxis, while bacteria on limestone were more likely to be lichen associated and have genes involved in photosynthesis and radiation resistance. Together these results indicate that rock‐dwelling microbes exhibit adaptations to survive the stresses of the rock surface, differ based on location, climate and rock type, and seem pre‐disposed to different ecological strategies (symbiotic versus free‐living lifestyles) depending on the rock type.

Mycobiota (fungi, lichens and myxomycetes) was examined in permanent plots following experiments of artificial drought (D) and nitrogen addition (N) and compared with untreated forest (C), in Scots pine stand planted on Arenosols. Species diversity and relationships between fungal community structure and environmental variables (plant species numbers and cover, bryophyte cover, soil and bark pH, tree mortality) were explored. Both D and N treatments lead to decrease of fungal species in general, however, responses of individual trophic and ecological groups varied. The strongest effect of the treatments was observed for soil fungi, especially mycorrhizal: numbers of fruiting species and ectomycorrhizal root tips decreased, and species composition has changed. Saprotrophic fungi reacted by changes in species composition but not in numbers. Of the studied environmental variables, the most significant effect on mycobiota had bryophyte and vascular plant cover as well as vascular plant species numbers. Keywords: fungi, lichens, myxomycetes, ectomycorrhizal root tips, artificial drought, nitrogen fertilization experiment.

Icefree, terrestrial, Antarctic ecosystems have a polar desert-like appearance with a scarce vegetation cover, completely dominated by bryophytes and lichens. Knowledge of the rich Antarctic lichen biodiversity, including c. 400 species, is therefore necessary, also for studies of other ecosystem components. The genus Psoroma is partly dominant there, and own ongoing research indicates that many of its members have been misunderstood. The aim of the present study is to describe Psoroma antarcticum as new to science, study its habitat ecology and total distribution, and include a genetic analysis with respect to its internal variation and relationship to other species. The species differs from the closely related species Psoroma hypnorum, in having distinctly cup-shaped apothecia with thalline excipuli without squamules and tomentose lower sides, in having shorter ascospores without apical nodulose extensions and thalli with grey-to-black melanins. It is shown to form a monophyletic clade based on an analysis of the ITS, LSU, and mtSSU loci, and this clade is included in the Psoroma s. str. clade, which includes P. hypnorum, Psoroma paleaceum, Psoroma buchananii, and Psoroma fruticulosum with high statistical support. The new species has its main distribution in the maritime South Shetland and South Orkney Islands of Antarctica, and most samples originate from King George Island, where it is common and an important component in polar desert-like vegetation. Scattered occurrences have also been found in Chilean Tierra del Fuego, South Georgia, and Bouvet Island. Keywords: King George Island · Taxonomy · Phylogeny · Pannariaceae.

Background: Cyanobacteria of the genus Nostoc are capable of forming symbioses with a wide range of organism, including a diverse assemblage of cyanolichens. Only certain lineages of Nostoc appear to be able to form a close, stable symbiosis, raising the question whether symbiotic competence is determined by specific sets of genes and functionalities. Results: We present the complete genome sequencing, annotation and analysis of two lichen Nostoc strains. Comparison with other Nostoc genomes allowed identification of genes potentially involved in symbioses with a broad range of partners including lichen mycobionts. The presence of additional genes necessary for symbiotic competence is likely reflected in larger genome sizes of symbiotic Nostoc strains. Some of the identified genes are presumably involved in the initial recognition and establishment of the symbiotic association, while others may confer advantage to cyanobionts during cohabitation with a mycobiont in the lichen symbiosis. Conclusions: Our study presents the first genome sequencing and genome-scale analysis of lichen-associated Nostoc strains. These data provide insight into the molecular nature of the cyanolichen symbiosis and pinpoint candidate genes for further studies aimed at deciphering the genetic mechanisms behind the symbiotic competence of Nostoc. Since many phylogenetic studies have shown that Nostoc is a polyphyletic group that includes several lineages, this work also provides an improved molecular basis for demarcation of a Nostoc clade with symbiotic competence. Keywords: Cyanobacteria, Nostoc, Lichen, Symbiosis, Symbiotic competence.

The electrochemical chlorination of physcion (=1,8‐dihydroxy‐3‐methoxy‐6‐methylanthracene‐9,10‐dione; 1) in AcOH and CH2Cl2 was investigated by cyclic voltammetry and prep.‐scale electrolysis. This approach provided access to a number of diverse biologically and pharmacologically interesting chlorinated secondary metabolites of lichen. Unlike the only previous literature report on the ‘classical’ chlorination of physcion (1), which allowed the preparation of 4‐chlorophyscion (2b), 4,5‐dichlorophyscion (3b), and 2,4,5‐trichlorophyscion (4), the present procedure also gave fragilin (=2‐chlorophyscion; 2a) and 2,4‐dichlorophyscion (3a), alongside the previously obtained 2b, 3b, and 4. All of these compounds, except for 2a, were isolated by column chromatography and medium‐pressure liquid chromatography (MPLC) and characterized by spectral data. The preparative electrolysis with a 2 F⋅mol−1 charge consumption in AcOH and 10 F⋅mol−1 in CH2Cl2 may have a practical synthetic utility, since the thus obtained product mixtures can be readily fractioned by column chromatography to afford pure 2b and 4, respectively. The regioselectivity of the reaction is explained by the resonance stabilization of the corresponding arenium cations ‐ potential products of an electrophilic attack of a ‘positive’ Cl species on the physcion molecule.

Lichens and mosses often share the same environmental conditions where they compete for substrate and other essential factors. Lichens use secondary metabolites as allelochemicals to repel surrounding plants and potential rivals. In mosses, endoreduplication leads to the occurrence of various ploidy levels in the same individual and has been suggested as an adaptation to abiotic stresses. Here, we show that also biotic factors such as usnic acid, an allelochemical produced by lichens, directly influenced the level of ploidy in mosses. Application of usnic acid changed the nuclei proportion and significantly enhanced the endoreduplication index in two moss species, Physcomitrella patens and Pohlia drummondii. These investigations add a new aspect on secondary metabolites of lichens which count as biotic factors and affect ploidy levels in mosses. Keywords: endopolyploidy, flow cytometry, lichens, mosses, usnic acid.

(2018): In situ long-term monitoring of recolonization by fungi and lichens after innovative and traditional conservative treatments of archaeological stones in Fiesole (Italy). - International Biodeterioration & Biodegradation, 132: 49–58.|
The research complements a study (Pinna et al., 2012) carried out to evaluate the effectiveness of mixtures of consolidants and water-repellent products (tetraethylorthosilicate, methylethoxy polysiloxane, Paraloid B72), with biocides (tributyltin oxide, dibutyltin dilaurate, copper nanoparticles) applied in situ to prevent biological growth on stones. The mixtures were tested over time on trial areas of three substrates - marble, sandstone, and plaster – in the archaeological site of Fiesole (Firenze, Italy). The 8-year-long study showed that the recolonization of the three substrates after the conservation treatment related mainly to their bioreceptivity and to the climatic conditions. Although the mixtures of water repellents and consolidants with biocides and copper nanoparticles were effective in reducing the recolonization, they did not play a crucial role in preventing biofilms and lichens growth. This study demonstrated that it was not possible to draw common conclusions regarding the products’ performance on the examined stones. Copper nanoparticles proved to be a suitable alternative to traditional biocides because they did not alter stones colour and contributed to the prevention of recolonization. The study provided information on the succession of fungi and lichens on untreated and treated stones, as well as on the variations of water repellency of treated stones. Keywords: Untreated and treated stones; Copper nanoparticles; Recolonization; Fungi; Lichens; Bioreceptivity.

Dry grasslands are listed among the habitats of conservation concern in Europe. Here, based on a multitaxon approach including vascular plants, bryophytes and lichens, we explored the effects of small-scale disturbance on lichen-rich dry grassland vegetation by surveying 60 sites across the Po Plain (Northern Italy). In particular, we evaluated the impact of human trampling and fecal pellet deposition by the alien invasive herbivore Sylvilagus floridanus. We found a soil-dependent response of multiple taxa to the impact of the herbivore. For plants, beside a negative effect of trampling, the interaction between fecal pellet amount and soil pH indicates that the negative effect of the invasive herbivore is stronger on acidic soils. Bryophyte cover increased with increasing soil pH, annual rainfall and fecal pellet, while it was not affected by trampling. Lichen richness and cover decreased with increasing soil pH. The marginal interaction between soil pH and amount of fecal pellet indicates that the more negative effects on lichens may be expected on calcareous soils. Trampling did not affect lichen patterns and the rainfall gradient marginally affected lichen cover with a negative effect. Lichen species richness is also negatively affected by increasing vascular plant cover. The main implications of this study for improving conservation are: (1) conservation practices should be tailored to organism and substrate type; (2) bryophyte and lichen diversity patterns are influenced also by climatic conditions, suggesting that the impact on these organisms may be exacerbated by climate change; and (3) strict conservation, even through active exclusion of wild fauna, of the most species-rich sites should be recommended, even if previous literature and the negative plant cover-lichen richness relationship found in this study indicate that moderate mechanical disturbance could be a practical tool to enhance cryptogams.

The effect of prescribed burning for conservation management of plant communities is controversial for moorlands growing on peat. These ecosystems provide many services that may be damaged by fire, hence it is important to fully assess its impact on all aspects of ecosystem structure and function experimentally over relatively long time‐scales. This paper describes change in community composition, major plant species, and plant functional types on moorland on peat in upland Britain over 60 years subject to 3 burning treatments after an initial burn in 1954/1955: no further burn and burning at 10‐ and 20‐year intervals (all ± sheep grazing). Data were analysed using multivariate and univariate methods. Vegetation composition and individual species abundance reflected the degree of disturbance. The least disturbed was dominated by Calluna vulgaris and pleurocarpous mosses, whereas the most disturbed treatment (burned every 10 years) had greater Eriophorum vaginatum, Sphagnum spp., acrocarpous mosses, liverworts, and lichens. The 20‐year treatment was intermediate in response disturbance. Repeated burning increased species abundance‐weighted Ellenberg values for moisture, reaction, light through time, and fertility; the exception was the 10‐year rotation for fertility. These confirm that prescribed burning is not deleterious to peat‐forming species (Eriophorum spp. and Sphagnum spp.), indeed these species were found in greater abundance in frequently burned treatments. It also confirms that a no‐burn policy will lead to increasing dominance of C. vulgaris, a flammable, fire‐adapted shrub, which increases summer wildfire risk. These results inform conservation management policy for moorland vegetation growing on peat; for this site, a 20‐year prescribed burning rotation is recommended.

The phytochemical investigation of the lichen Parmotrema sancti‐angelii afforded three racemic compounds, sanctis A–C, which feature an original dibenzo‐2,8‐dioxabicyclo[3.3.1]nonane scaffold. These compounds were structurally characterized by extensive NMR spectroscopy analyses, comparison between experimental and theoretical NMR spectroscopic data, and X‐ray crystallography. These metabolites are similar to procyanidin A and display a methyl group instead of a pendant aromatic ring at C‐9, a so far unprecedented structural feature. A biosynthetic route to sanctis A–C is proposed.

The colonization–extinction dynamics of many species are affected by the dynamics of their patches. For increasing our understanding of the metapopulation dynamics of sessile species confined to dynamic patches, we fitted a Bayesian incidence function model extended for dynamic landscapes to snapshot data on five epiphytic lichens among 2083 mapped oaks (dynamic patches). We estimate the age at which trees become suitable patches for different species, which defines their niche breadth (number of suitable trees). We show that the colonization rates were generally low, but increased with increasing connectivity in accordance with metapopulation theory. The rates were related to species traits, and we show, for the first time, that they are higher for species with wide niches and small dispersal propagules than for species with narrow niches or large propagules. We also show frequent long-distance dispersal in epiphytes by quantifying the relative importance of local dispersal and background deposition of dispersal propagules. Local stochastic extinctions from intact trees were negligible in all study species, and thus, the extinction rate is set by the rate of patch destruction (tree fall). These findings mean that epiphyte metapopulations may have slow colonization–extinction dynamics that are explained by connectivity, species traits, and patch dynamics. Key words: Bayesian inference; colonization–extinction dynamics; dispersal; incidence function model; lichens; niche breadth; patch-tracking metapopulation; tree age.

Architrypethelium murisporum Luangsuphabool, Lumbsch & Sangvichien is described for a crustose lichen occurring in dry evergreen forest in Thailand. It is characterised by a green to yellow-green corticated thallus, perithecia fused in black pseudostromata with white rim surrounding the ostiole and small, hyaline and muriform ascospores. Currently, all species in the genus Architrypethelium have transversely septate ascospores, hence the discovery of this new species indicates that ascospore septation is variable within the genus, similar to numerous other groups of lichen-forming ascomycetes. Phylogenetic analyses of two loci (mtSSU and nuLSU) supported the position of the new species within Architrypethelium. This is the first report of the genus in Southeast Asia. Keywords: lichens, taxonomy, phylogeny, tropical diversity, Southeast Asia, Trypetheliales.

Loxospora cristinae sp. nov. is a sterile corticolous lichen characterized by sorediate, thin, smooth, folded, cracked-areolate and non-verruculose to partly verruculose thalli, soralia soon becoming confluent and the production of 2’-O-methylperlatolic acid. The new species is similar to the recently described L. assateaguensis and L. confusa, which are also sterile and contain 2’-O-methylperlatolic acid. Loxospora assateaguensis can be readily distinguished from the new species by the thallus, which is distinctly verruculose almost from the edge and pustular, and the circular soralia developing apically on the thalline verrucae, and from L. confusa by the presence of granular isidia. The distinction of all three species and their phylogenetic position are also corroborated by molecular approaches using mtSSU and ITS markers. The new species has been found so far only in well preserved forests in Poland. Keywords: Fungi, biodiversity, sorediate lichens, crustose lichens, taxonomy, Sarrameanaceae.

Foliicolous lichens are formed by diverse, highly specialized fungi that establish themselves and complete their life cycle within the brief duration of their leaf substratum. Over half of these lichen-forming fungi are members of either the Gomphillaceae or Pilocarpaceae, and associate with Trebouxia-like green algae whose identities have never been positively determined. We investigated the phylogenetic affinities of these photobionts to better understand their role in lichen establishment on an ephemeral surface. Thallus samples of Gomphillaceae and Pilocarpaceae were collected from foliicolous communities in southwest Florida and processed for sequencing of photobiont marker genes, algal cultivation and/or TEM. Additional specimens from these families and also from Aspidothelium (Thelenellaceae) were collected from a variety of substrates globally. Sequences from rbcL and nuSSU regions were obtained and subjected to Maximum Likelihood and Bayesian analyses. Analysis of 37 rbcL and 7 nuSSU algal sequences placed all photobionts studied within the provisional trebouxiophycean assemblage known as the Watanabea clade. All but three of the sequences showed affinities within Heveochlorella, a genus recently described from tree trunks in East Asia. The photobiont chloroplast showed multiple thylakoid stacks penetrating the pyrenoid centripetally as tubules lined with pyrenoglobuli, similar to the two described species of Heveochlorella. We conclude that Heveochlorella includes algae of potentially major importance as lichen photobionts, particularly within (but not limited to) foliicolous communities in tropical and subtropical regions worldwide. The ease with which they may be cultivated on minimal media suggests their potential to thrive free-living as well as in lichen symbiosis.

(2015): Molecular phylogeny and ultrastructure of the lichen microalga Asterochloris mediterranea sp. nov. from Mediterranean and Canary Islands ecosystems. - International Journal of Systematic and Evolutionary Microbiology, 65: 1838–1854.|
The microalgae of the genus Asterochloris are the preferential phycobionts in Cladonia, Lepraria and Stereocaulon lichens. Recent studies have highlighted the hidden diversity of the genus, even though phycobionts hosting species of the genus Cladonia in Mediterranean and Canarian ecosystems have been poorly explored. Phylogenetic analyses were made by concatenation of the sequences obtained with a plastid – LSU rDNA – and two nuclear – internal transcribed spacer (ITS) rDNA and actin – molecular markers of the phycobionts living in several populations of the Cladonia convoluta-Cladonia foliacea complex, Cladonia rangiformis and Cladonia cervicornis s. str. widely distributed in these areas in a great variety of substrata and habitats. A new strongly supported clade was obtained in relation to the previously published Asterochloris phylogenies. Minimum genetic variation was detected between our haplotypes and other sequences available in the GenBank database. The correct identification of the fungal partners was corroborated by the ITS rDNA barcode. In this study we provide a detailed characterization comprising chloroplast morphology, and ultrastructural and phylogenetic analyses of a novel phycobiont species, here described as Asterochloris mediterranea sp. nov. Barreno, Chiva, Moya et S ˇ kaloud. A cryopreserved holotype specimen has been deposited in the Culture Collection of Algae of Charles University in Prague, Czech Republic (CAUP) as CAUP H 1015. We suggest the use of a combination of several nuclear and plastid molecular markers, as well as ultrastructural (transmission electron and confocal microscopy) techniques, both in culture and in the symbiotic state, to improve novel species delimitation of phycobionts in lichens.

Water-soluble polysaccharides from Umbilicaria tornata (UTP) were purified and preliminarily characterized. The antioxidant and antitumor activities of crude UTP and two purified fractions (UTP-1 and UTP-2) were evaluated using in vitro experiments. The results showed that the molecular weights of UTP-1 and UTP-2 were 84.86 and 28.66 kDa, respectively. Both UTP-1 andUTP-2were composed of glucose and xylose,with their molar ratios being 1.3:0.9 and 0.9:4.6, respectively. In addition, crude UTP, UTP-1 and UTP-2 showed dose-dependent DPPH and hydroxyl radical scavenging and reducing activities. However, crude UTP exhibited stronger antioxidant activity than UTP-1 and UTP-2, particularly in terms of DPPH radicals. Crude UTP and the two purified fractions inhibited the growth of HeLa, HepG2, A375, MCF-7, SGC7901 and Caco2 cancer cells in vitro. Compared with UTP-1 and UTP-2, crude UTP presented significantly higher antitumor activity in vitro against HeLa and HepG2 cells (p < 0.05). These findings provide a scientific basis for the deeper exploration and resource development of U. tornata. Keywords Umbilicaria Tornata . Polysaccharides . Purification . Activity.

Fungi exhibit some of the greatest reproductive diversity across Eukaryotes. In addition to sexual and asexual reproduction, fungi engage in parasexual (mitotic recombinatorial) processes to acquire new genetic variation. Reproduction has been studied extensively in numerous free-living fungi but comparatively less knowledge exists for lichenized fungi, which are assumed to reproduce only through sexual spores, asexual conidia, and specialized asexual lichen propagules. We present a new conceptual framework describing reproductive modes in lichens that includes sexual and asexual processes as well as accommodating the possibility of parasexual reproduction. To support the plausibility of some of these modes of reproduction, we reviewed data spanning more than 200 years of anatomical investigation.We recovered evidence supporting the possibility of 22 of 27 possible modes of reproduction and found no counter-evidence to suggest the remaining five do not occur in nature. This conceptual framework allows for a greater plurality of reproductive processes than previously acknowledged in lichens, exceeding that of their non-lichenized relatives. Keywords: Genetic, haploid, meiosis, mitosis, parasexual, ploidy, recombination, symbiosis.

In this study, we aimed to determine the accumulations of 210Po and 210Pb in soil and lichen samples in Köprübaşı. The Köprübaşı district is home to the largest uranium deposits in Turkey. To date, there has been no study recorded in the literature related to 210Po and 210Pb depositions in lichens in Köprübaşı. Six different lichen species (Cladonia convoluta, Parmelina tiliacea, Physcia stellaris, Pleurosticta acetabulum, Xanthoparmelia conspersa, and Xanthoria parietina) as well as soil samples were collected from seven sampling locations around Köprübaşı. Lichens were used as biomonitors for 210Po and 210Pb deposition. The 210Po and 210Pb activity concentrations were measured in all the samples by alpha spectrometry. The activity concentrations in the lichen samples ranged from 64 to 577 Bq kg−1 with an average of 266 Bq kg−1 for 210Po and from 78 to 565 Bq kg−1 with an average of 333 Bq kg−1 for 210Pb. The activity ratios of 210Po/210Pb ranged from 0.80 to 1.99. In the lichen species, the mean 210Po activity values varied from 154 Bq kg−1 in Pleurosticta acetabulum to 390 Bq kg−1 in Xanthoparmelia conspersa. The range of the mean 210Pb activity was between 153 Bq kg−1 in Cladonia convoluta and 378 Bq kg−1 in Parmelina tiliacea. In the soil samples, 210Po and 210Pb activity concentrations were ranged from 14 to 1268 Bq kg−1 and from 19 to 1113 Bq kg−1, respectively. While the values of 210Po and 210Pb measured in the lichen samples are comparable with those of the literature, the results of 210Po and 210Pb in the soil taken from the uranium mine are higher than the results of the literature studies. Keywords: 210Po; 210Pb; Manisa; Lichen.

Peculiarities of the forest vegetation dynamics and the main factors and mechanisms of environmental filtering were studied on loose deposits of the Tolbachinskii Dol Volcanic Plateau (Kamchatka) by means of plant life-form analysis. It was found that, in the earlier stages of plant succession, polycarpic herbs, acrocarpous mosses, and fruticulose lichens dominated. Forest communities of 35 years old differed from the old-growth ones by the proportions of plant life-forms and the total coverage. Environmental filtering is manifested by the most successful development of plants having special morphological adaptations of belowground systems to loose unstable substrata.

Fungal communities play critical roles in maintaining the structure and function of biocrust in desert ecosystems. However, the successional changes of fungal communities along the biocrust development stages are not fully understood. In this study, we investigated the fungal community compositions inhabiting different biocrust successional stages (bare sand, algal crusts, lichen crusts, and moss crusts) and their relationships with environmental factors in the Gurbantunggut Desert of Northwestern China. Our results showed that fungal diversity did not change significantly along the successional stages. However, fungal biomass in lichen and moss crusts was significantly higher than those in bare sand and algal crusts. Fungal communities also showed significant successional changes with biocrust development from bare sand, algal crusts, lichen crusts, to moss crusts. At the class level, algal and lichen crusts were dominated by Dothideomycetes, Eurotiomycetes, and Lecanoromycetes, while moss crusts were dominated by unidentified Ascomycota, Eurotiomycetes, and Dothideomycetes. Successional changes also occurred at genera level. The dominant OTUs were affiliated to unknown genera in Pleosporales, Humicola, and unknown genera in Chaetomiaceae in bare sand; Endocarpon, unknown genera in Pleosporaceae, and Humicola in algal crusts; Endocarpon, Heteroplacidium, and unknown genera in Lecanorales in lichen crusts; and Heteroplacidium, Endocarpon and unknown genera in Pleosporales in moss crusts. Changes in soil organic C, conductivity, and soil bulk density were associated to the shifts in fungal community compositions, suggesting that the accumulations of soil nutrients and salts may drive the changes in biocrust fungal compositions.

Main conclusion: Drought tolerance was greater in the whole lichen than in its isolated photobiont. Cell turgor state has an influence on the functionality of photosynthetic process in lichens. Irreversible thermodynamics is widely used to describe the water relations of vascular plants. However, poikilohydrous organisms like lichens and aeroterrestrial microalgae have seldom been studied using this approach. Water relations of lichens are generally addressed without separate analysis of the mycobiont and photobiont, and only few studies have correlated changes in photosynthetic efficiency of dehydrating lichens to accurate measurements of their water potential components. We measured water potential isotherms and chlorophyll a fluorescence in the lichen Flavoparmelia caperata harvested in different seasons, as well as in its isolated photobiont, the green alga Trebouxia gelatinosa, either exposed to water stress cycles or fully hydrated. No significant seasonal trends were observed in lichen water relations parameters. Turgor loss point and osmotic potential of the whole thallus were significantly lower than those measured in the photobiont, while differences between the water stressed photobiont and controls were not significant. Dehydration-induced drop of Fv/Fm was correlated with turgor loss, revealing that the photosynthetic activity of lichens partly depends on their turgor level. We provided one of the first quantitative evidences of the influence that turgor status could exert on the functionality of photosynthetic processes in lichens. Keywords: Chlorophyll fluorescence · Desiccation tolerance · Flavoparmelia caperata · Osmotic potential · Trebouxia gelatinosa · Turgor loss point.

Fungi are a megadiverse group of organisms, they play major roles in ecosystem functioning and are important for human health, food production and nature conservation. Our knowledge on fungal diversity and fungal ecology is however still very limited, in part because surveying and identifying fungi is time demanding and requires expert knowledge. We present a method that allows anyone to generate a list of fungal species likely to occur in a region of interest, with minimal effort and without requiring taxonomical expertise. The method consists of using a cyclone sampler to acquire fungal spores directly from the air to an Eppendorf tube, and applying DNA barcoding with probabilistic species identification to generate a list of species from the sample. We tested the feasibility of the method by acquiring replicate air samples from different geographical regions within Finland. Our results show that air sampling is adequate for regional‐level surveys, with samples collected >100 km apart varying but samples collected <10 km apart not varying in their species composition. The data show marked phenology, and thus obtaining a representative species list requires aerial sampling that covers the entire fruiting season. In sum, aerial sampling combined with probabilistic molecular species identification offers a highly effective method for generating a species list of air‐dispersing fungi. The method presented here has the potential to revolutionize fungal surveys, as it provides a highly cost‐efficient way to include fungi as a part of large‐scale biodiversity assessments and monitoring programs. Cladonia, Lepraria, Bryoria, Physcia and Phaeophyscia listed in the table among the most abundant lichen genera.

Comparative phytochemical analysis of five lichen species [Parmotrema tinctorum (Delise ex Nyl.) Hale, P. andinum (Mull. Arg.) Hale, P. praesorediosum (Nyl.) Hale, P. grayanum (Hue) Hale, P. austrosinense (Zahlbr.) Hale] of Parmotrema genus were performed using two complementary UPLC–MS systems. The first system consists of high resolution UPLC-QToF-MS/MS spectrometer and the second system consisted of UPLC–MS/MS in Multiple Reaction Monitoring (MRM) mode for quantitative analysis of major constituents in the selected lichen species. The individual compounds (47 compounds) were identified using Q-ToF-MS/MS, via comparison of the exact molecular masses from their MS/MS spectra, the comparison of literature data and retention times to those of standard compounds which were isolated from crude extract of abundant lichen, P. tinctorum. The analysis also allowed us to identify unknown peaks/compounds, which were further characterized by their mass fragmentation studies. The quantitative MRM analysis was useful to have a better discrimination of species according to their chemical profile. Moreover, the determination of antioxidant activities (ABTS+ inhibition) and Advance Glycation Endproducts (AGEs) inhibition carried out for the crude extracts revealed a potential antiglycaemic activity to be confirmed for P. austrosinense.

European landscape conservation includes the recognition of inter-related ‘ancient’ and ‘old-growth’ woodland. Ancient woodland is defined by its temporal continuity, which can be measured through its consistent occurrence on historic maps over a period of time, typically several centuries. Old-growth woodland has attributes of both temporal continuity and structural complexity; European old-growth woodland is now extremely rare and a valuable conservation resource. Indicator species provide recognition of old-growth woodland, through traits that are sensitive to its defining features: (i) dispersal limitation demanding temporal continuity of suitable habitat prior to colonisation (as is associated with ancient woodland), and/or (ii) specialist niches associated with old and senescent trees (which may or may not be found in ancient woodland, depending on its past management). To test the response of indicators to each of these features, niche models were developed for lichen epiphytes in an ancient and structurally diverse woodland stand, thus corresponding to ‘old-growth’ condition. Models were projected for the ancient and an adjacent regenerated stand. There was less suitable habitat in the regenerated stand, and a lower proportion of suitable habitat was occupied. Nevertheless, indicators had colonised from the ancient to the regenerated stand within 50 years. Viewed against the background of previous work, we conclude that landscape context – the spatial relationship between ancient and regenerated woodland – is critical to the interpretation of indicators, which are perhaps better conceptualised as markers of threat and conservation value than independent measures of woodland history.

Ecophysiological biomarkers and atmospheric contamination due to glyphosate and trace elements were monitored in a southern Italian agricultural district by means of transplanted thalli of the lichen Pseudevernia furfuracea. Glyphosate exhibited a significant geographical pattern (east side > west side) and a drift source area equal to 32%of the monitoring sites. Moreover, based on the surface area of the study area and a wind quantitative relationship (WQR) with glyphosate thalli concentrations, our data support the idea that pesticide drift extends over an area of several square kilometers. Of the eight elements preliminarily classified as enriched, four were considered prevalently of geogenic origin (Al, Ti, Ni, Co) and four of anthropogenic origin (Cu, Mn, Sn, Sb), although only Sb and Cu passed rigorous statistical testing supporting a real difference from pre-exposure levels. The contribution of local sources was evaluated based on the relative increase of Cu, Mn, Sb, and Sn versus Ti. Cu and Mn were associated mainly with a biomass power plant (BPP), with Cu showing extremely high levels of contamination involving 20% of the monitoring sites. Sb and Sn were associated with spatial variation of the traffic rate. The mycobiont and photobiont showed an evident zonation of the levels of their physiological parameters, with oxidative stress being significantly associated with both the biomass power plant and Cu/Ti. Our results suggest that croplands are potentially exposed to various hazards: overexposure to pesticides due to drift processes, diffuse low traffic levels promoting Sb enrichment, and acute Cu pollution affected by BPP emissions.

Management of ancient trees constitutes a major dilemma in the conservation of associated biodiversity. While traditional methods are often advocated, such practices may incur considerable costs and their effects have rarely been scientifically evaluated. We compared the communities of lichenized fungi, non-lichenized fungi, and bryophytes among equal number of coarse previously pollarded and unmanaged trees (n = 340). On 400 Ulmus glabra and 280 Fraxinus excelsior trees at 62 sites in Norway, we found 209 lichenized fungi, 128 non-lichenized fungi, and 115 bryophytes. Pollarded trees were richer in microhabitats than unmanaged trees and had significantly higher richness of bryophytes (ash) and non-lichenized fungi (ash and elm), the latter increasing with the availability of dead wood, cavities and coarse bark structure in pollarded trees. Further, the average total number of red-listed species, and red-listed lichenized fungi separately, were significantly higher on pollarded versus unmanaged trees, with diversity related to trunk circumference, depth of bark fissures and number of cavities. Our results underline the importance of microhabitats associated with old trees, but we cannot establish with certainty the importance of pollarding per se. Since we did not find any negative effect of canopy cover for community diversity, we assume that old trees with rich epiphytic communities can develop without management intervention. The high share (37 out of 49) of red-listed species occurring on unmanaged trees, and the fact that 11 red-listed species were found exclusively on unmanaged trees, may further indicate that unmanaged trees can with time replace the ancient pollarded trees as habitats for rich cryptogamic communities.

Lichens are one of the common dominant biota in biological soil crusts (biocrusts), a community that is one of the largest in extent in the world. Here we present a summary of the main features of the lifestyle of soil crust lichens, emphasizing their habitat, ecophysiology and versatility. The soil crust is exposed to full light, often to high temperatures and has an additional water source, the soil beneath the lichens. However, despite the open nature of the habitat the lichens are active under shady and cooler conditions and avoid climate extremes of high temperature and light. In temperate and alpine habitats they can also be active for long periods, several months in some cases. They show a mixture of physiological constancy (e.g. similar activity periods and net photosynthetic rates) but also adaptations to the habitat (e.g. the response of net photosynthesis to thallus water content can differ for the same lichen species in Europe and the USA and some species show extensive rhizomorph development). Despite recent increased research, aspects of soil crust ecology, for example under snow, remain little understood. activeperiod,adaptation,algae,bryophytes,dew,photosynthesis,poikilohydric,waterrelations

This paper, based on data from the latest checklist of Italy, analyzes the distribution patterns of rare and common lichen species within biogeographically homogeneous versus heterogeneous areas of Italy, and the relationships with some main drivers of rarity and commonness. The following data were used: 1) commonness-rarity values of 2565 species in nine ecoregions; 2) frequency of 353 nationally rare and 387 nationally common species in 21 administrative regions. The following functional and ecological traits were considered: growth form, photobiont(s), type of reproduction, substrata, bioclimatic range, ecological indicator values for aridity and eutrophication, and poleophoby. Within each ecoregion, rare species by far outweigh common species but about one third of these are common in other ecoregions. At the level of regional floras, rarity is significantly associated with epiphytic substrata, non-trebouxioid photobionts and high air humidity, while commonness is associated with saxicolous substrata, trebouxioid photobionts and eutrophication. Rarity seems to mainly depend on two factors, bioclimate (many rare species are outside the limit of their bioclimatic optima) and reduced availability of suitable habitats (e.g. old-growth forests), while commonness is mainly related to disturbance (eutrophication, creation of drier habitats). Most of the nationally rare lichens belong to an oceanic-suboceanic element with tropical affinities or to a small set of continental species with their optima in the dry steppe biome, which suggests that many rare species can persist in microrefugia, that is sites with microclimates that support small populations of species beyond the boundaries of the climatic limits of their main distributions. bioclimate, disturbance, eutrophication, functional traits, microrefugia, photobionts

Currently, change in lichen community structure depends on a combination of several pollutants instead of just one. Consequently, alpha lichen diversity no longer represents an effective response variable for assessing trends in atmospheric pollutants over time. Here we investigated the value of the relationship between alpha diversity and different aspects of gamma diversity (similarity, replacement and differences in richness of species) together with that of beta diversity (calculated as the sum of replacement and difference in richness of species), for assessing complex variations in epiphytic lichen communities in response to a changing pollution scenario. We considered an area subjected to extreme variation in atmospheric pollution in recent decades and explored temporal and spatial aspects of lichen community succession over short-, intermediate- and long-term reference periods. We found that variation in lichen communities for long- and intermediate-term reference periods was strongly dependent on the alpha diversity of single trees at the beginning of the observation period. The occurrence of nitrophytic species, which responded to the decrease in SO2 concentrations, contribute to this trend. The effect of land use was observed only over long observation periods, with trees in urban areas showing less variation than those located in rural areas. In particular, the analysis of similarity, species replacement and differences in richness of tree pairs demonstrated that trends and patterns within lichen communities are neither always nor to the same extent associated with alpha diversity. Our results show that a thorough study of gamma diversity, including beta diversity and similarity, is required to detect changes in air quality in long-term biomonitoring surveys. landuse,lichendiversity,nitrophytes,oxidesofnitrogen,speciesreplacement,sulphurdioxide

Intrathalline phycobiont diversity was investigated in a rosette-forming lichen, Parmotrema pseudotinctorum, using a combination of Sanger sequencing, 454-pyrosequencing, conventional light and confocal microscopy, and transmission electron microscopy. A total of 39 thalli sampled in five Canary Island populations were investigated. Three novel lineages of lichen phycobionts were detected, all being inferred within the Trebouxia clade G. The most abundant phycobiont lineage, occurring in all lichen populations investigated, is described here as Trebouxia crespoana sp. nov. This species produces spherical to pyriform cells possessing a crenulate chloroplast with lobes elongated at their ends, and one corticola-type pyrenoid with very thin, unbranched tubules of curved profile. Trebouxia crespoana is clearly distinguished from all other Trebouxia species by a characteristic cap-like cell wall thickening produced on one side of vegetative cells, and the larger size of vegetative cells that reach 21(–26) μm in diameter. 454-pyrosequencing, Canary Islands, lichens, morphology, phycobionts, ultrastructure

Some definitions of the term ‘lichen’ have often emphasized the role of the mycobiont as exhabitant in the symbiosis. Mastodia tessellata and Turgidosculum ulvae, both forming lichen-like associations with foliose algae, have traditionally defied that definition. In this study, we delve into the poorly known association of T. ulvae with Blidingia minima. Using four molecular markers (nrLSU, nrSSU, RPB1, mtSSU) we show that T. ulvae is a member of the family Verrucariaceae, closely related to the marine species Verrucaria ditmarsica. The presence of bitunicate asci and single-cell ascospores is confirmed. Our analysis of a fragment of the rbcL marker demonstrates that the photosynthetic partner belongs to B. minima, although relationships within this taxon remain unclear. Transmission electron microscopy allowed us to illustrate how T. ulvae interacts with Blidingia cells, and how haustoria in that species differ from those previously investigated in other marine lichen-forming fungi.

Lasallia hispanica (Frey) Sancho & A. Crespo is one of three Lasallia species occurring in central-western Europe. It is an orophytic, photophilous Mediterranean endemic which is sympatric with the closely related, widely distributed, highly clonal sister taxon L. pustulata in the supra- and oro-Mediterranean belts. We sequenced the genome of L. hispanica from a multispore isolate. The total genome length is 41·2 Mb, including 8488 gene models. We present the annotation of a variety of genes that are involved in protein secretion, mating processes and secondary metabolism, and we report transposable elements. Additionally, we compared the genome of L. hispanica to the closely related, yet ecologically distant, L. pustulata and found high synteny in gene content and order. The newly assembled and annotated L. hispanica genome represents a useful resource for future investigations into niche differentiation, speciation and microevolution in L. hispanica and other members of the genus.

The family Peltulaceae is currently composed of the three genera Peltula, Phyllopeltula and Neoheppia. The last two genera, both with two species, are distinguished from Peltula only by a small number of morphological characters. The morphology of the genus Peltula varies from peltate-umbilicate thalli to squamulose-semifruticose or squamulose-compound types, as well as subfoliose-compound and crustose types. All types have an upper epinecral layer and possess medullary cavities of various sizes; a lower cortex is normally present but is usually not developed in the subfoliose and crustose types. The genera Neoheppia and Phyllopeltula differ from the common Peltula morphology by crustose-areolate and subfoliose-compound thalli, respectively. Both Neoheppia and Phyllopeltula are additionally characterized by the absence of medullary cavities and lower cortices. To investigate the phylogenetic validity of Phyllopeltula and Neoheppia, we sequenced six loci from representatives of these two genera together with 37 species from Peltula. Despite the relatively high amount of conflict among loci, the results clearly indicate that both Phyllopeltula and Neoheppia are not monophyletic, and are nested within the genus Peltula. Consequently, we subsumed species of these two genera within the genus Peltula. Neoheppia, Peltula, phylogeny, Phylopeltula, taxonomy

Species richness is not evenly distributed across the tree of life and a limited number of lineages comprise an extraordinarily large number of species. In lichen-forming fungi, only two genera are known to be ‘ultradiverse’ (>500 species), with the most diverse genus, Xanthoparmelia, consisting of c. 820 species. While Australia and South Africa are known as current centres of diversity for Xanthoparmelia, it is not well known when and where this massive diversity arose. To better understand the geographical and temporal context of diversification in this diverse genus, we sampled 191 Xanthoparmelia specimens representing c. 124 species/species-level lineages from populations worldwide. From these specimens, we generated a multi-locus sequence data set using Sanger and high-throughput sequencing to reconstruct evolutionary relationships in Xanthoparmelia, estimate divergence times and reconstruct biogeographical histories in a maximum likelihood and Bayesian framework. This study corroborated the phylogenetic placement of several morphologically or chemically diverse taxa within Xanthoparmelia, such as Almbornia, Chondropsis, Karoowia, Namakwa, Neofuscelia, Omphalodiella, Paraparmelia, Placoparmelia and Xanthomaculina, in addition to improved phylogenetic resolution and reconstruction of previously unsampled lineages within Xanthoparmelia. Our data indicate that Xanthoparmelia most likely originated in Africa during the early Miocene, coinciding with global aridification and development of open habitats. Reconstructed biogeographical histories of Xanthoparmelia reveal diversification restricted to continents with infrequent intercontinental exchange by long-distance dispersal. While likely mechanisms by which Xanthoparmelia obtained strikingly high levels of species richness in Australia and South Africa remain uncertain, this study provides a framework for ongoing research into diverse lineages of lichen- forming fungi. Finally, our study highlights a novel approach for generating locus-specific molecular sequence data sets from high throughput metagenomic reads.

Hypotrachyna is a speciose genus of primarily tropical and oceanic lichen-forming fungi. It includes species with distinct distribution patterns, such as pantropical, restricted and disjunct species. We used a dataset of mitochondrial SSU, nuclear ITS and LSU ribosomal DNA from 89 specimens to study the historical biogeography of the genus. We employed Bayesian and maximum likelihood approaches for phylogenetic analyses, a likelihood-based approach to ancestral area estimation, and a Bayesian approach to estimate divergence times of major lineages within the genus based on molecular evolutionary rates for ITS and a secondary calibration point at the Hypotrachyna clade – Parmeliopsis split. Our analyses suggest that the genus might have originated in the Neotropics during the Eocene and that the split of major lineages happened primarily during the Eocene and Oligocene. The major diversification within those clades is estimated to have occurred during the Miocene. Pantropical species distributions are explained by long-distance dispersal. A number of currently accepted species were found to be non-monophyletic, illustrating that the delimitation of species in the genus needs attention. ancestral areas, distribution, Neotropics, parmelioid lichens, phylogeny

The lichen species Cladonia angustiloba is characterized by a well-developed primary thallus and narrow squamules which show deep incisions, and the presence of usnic and fumarprotocetraric acids. Morphologically it is similar to C. foliacea and C. convoluta, from which it can be distiguished by the squamule size and morphology. Since similar characters were used to distinguish C. foliacea from C. convoluta which do not represent different lineages, it is necessary to examine the taxonomic status of C. angustiloba by means of DNA sequences. In this study, the species delimitation within the C. foliacea complex was studied by sequencing three loci, ITS rDNA, cox1 and RPB2. The data were analyzed by means of phylogenetic and species delimitation methods (GMYC, PTP, ABGD and BPP). Our results show that none of the three species is monophyletic. Most of the species delimitation methods did not support the current species as evolutionary lineages. Only some of the BPP analyses supported C. angustiloba as a species distinct from C. foliacea and C. convoluta. However, the hypothesis that considers the C. foliacea complex as constituted by a unique species obtained the best Bayes Factor value. Therefore, C. angustiloba and C. convoluta are synonymized with C. foliacea. A new, thoroughly checked synonymy with typifications of the whole C. foliacea complex is presented.

This is the first part of an ongoing taxonomic treatment of Bunodophoron (Sphaerophoraceae, Lecanorales) in the Neotropics, based on the molecular phylogenetic analysis of three markers together with studies of morphology and chemistry, and using the general mixed Yule coalescence (GMYC) method to delimit species boundaries. In the Neotropics, species in this genus grow on the ground or on shrubs in the páramos, and as epiphytes in the montane rainforests. We describe here a new species from the páramos of Colombia, Bunodophoron crespoae Soto, M. Prieto & Wedin sp. nov., and discuss its distinction from another large and common páramo species Bunodophoron flabellatum (Hue) Soto, M. Prieto & Wedin comb. nov. Both species are primarily terrestrial in the páramos, although B. flabellatum may occasionally also grow as an epiphyte. Bunodophoron crespoae is characterized by the white, c. 10–13 cm long, subterete to narrowly flattened, main branches. It differs from the otherwise similar B. flabellatum by being distinctly subterete, more abundantly branched, and by having smaller ascospores. Both are distinguished from the primarily epiphytic B. melanocarpum by the considerably larger thallus size, with the main branches of B. melanocarpum rarely exceeding 3·5 cm in length and 2 mm in width. lichenized fungi, nomenclature, phylogeny, species boundaries, systematics, taxonomy

The species Psoroma spinuliferum is described here as new to science. It is only known from the holotype on a Picea sitchensis trunk near a sea-shore in southern, coastal Alaska. The species is distinct in having short, brittle, spinule-like hairs on both apothecium margins, thalline squamules and on pulvinate to coarsely coralloid cephalodia with emerald-colored Nostoc photobionts. These spinules are unique within Pannariaceae as they are developed on both the chlorobiont and on one of two cyanobionts, but it is uncertain whether they can act as vegetative propagules. The presence of two types of cephalodia is also unique within Pannariaceae. The second type consists of glabrous, small-foliose, geotropically arranged cephalodia, containing a Nostoc strain with cells of an intense ultramarine color, when observed after long storage. The species also has shorter ascospores than Psoroma paleaceum, another hairy species. The hair types of Psoroma hypnorum and P. paleaceum are here by contrast referred to as tomentum and scales, respectively.

DNA sequencing techniques and molecular and phylogenetic analyses have developed rapidly over a short time, finding application in fields across biology and medicine. The field of lichenology is no exception, with hundreds of studies utilizing DNA sequences to reconstruct phylogenies and uncover the evolutionary histories of populations and species. Given the dramatic advancements of sequencing technologies, analytical techniques and computational capabilities, an assessment of trends in molecular lichen research is timely. We present a literature meta-analysis that reviews the existing published molecular and phylogenetic research using traditional (e.g., Sanger) and next-generation (e.g., Illumina) sequencing technologies. Specifically we (i) determine how molecular data have been applied to lichens thus far, (ii) document and discuss trends in sequence data application, (iii) examine taxonomic representation and biases at the family level, and (iv) outline avenues of future research as well as highlight areas where targeted study is urgently needed. Keywords: Evolution, fungi, genetics, molecular biology, review, meta-analysis, phylogenetics, photobionts, symbiosis.

The global increase in air pollution has a number of consequences including damage to our environment and health. Bioindicators are living organisms which reveal certain qualities of our environment with their absence or presence. This is useful in identifying polluted areas in order to manage pollution levels. Parmelia sulcata is said to be a pollution-tolerant lichen and consequently a bioindicator. We wished to test P. sulcata’s ability as a bioindicator, indicating poor air quality with its presence. We used randomized quadrat sampling of 80 trees over four municipalities on the Avalon Peninsula of Newfoundland, Canada with increasing human populations as a proxy for pollution. Results suggest that P. sulcata is not an ideal bioindicator of high pollution. It was absent or diseased in areas of highest pollution and present in areas of low-medium pollution levels. We recommend further studies evaluate P. sulcata’s potential as a bioindicator of lowmedium air pollution. Keywords. Avalon Peninsula, monitoring, pollution-tolerant, urban.

The invalid combination Stirtonia alba (M¨ull. Arg.) ined., based on Arthonia alba M¨ull. Arg., is listed for the continental United States in several important online repositories, including CNALH, USDA PLANTS and EOL. Although Arthonia alba belongs in Stirtonia, the name cannot be used in that combination, as it is blocked by S. alba Groenh. ex Makhija & Patw., a species described from Java, Indonesia, and both taxa are distinct morphologically, anatomically and chemically. Here, we resolve this nomenclatural impasse by proposing the new name S. caribaea for A. alba. We examined further material identified as ‘‘A. alba / S. alba’’ from North America and the Caribbean. Specimens ascribed to ‘‘S. alba (M¨ull. Arg.) ined.’’ from North America (Louisiana, Florida) were found to be misidentifications in other genera, with only one collection confirmed as a Stirtonia. This specimen was determined to be S. punctiformis, and is here reported as new to North America, representing a northward range extension from Central America and northern South America. Therefore, the name ‘‘Arthonia alba M¨ull. Arg.’’ listed under Stirtonia in the North American lichen checklist should be removed. Caribbean material previously identified as A. alba was found to represent two species: A. alba s.str., here renamed S. caribaea, known from Cuba and St. John of the U.S. Virgin Islands; and S. borinquensis, which we describe as a new species from Puerto Rico.

Our collecting of lichens in Lawrence County, Pennsylvania has increased the known diversity to nearly 50 taxa. Before this study, the most recent published reports on lichens for the county were recorded nearly 60 years ago; hence, many of these records were historic. These aforementioned studies combined with the CNALH database have identified more than 30 taxa that have occurred in Lawrence County which totals 24 lichen species reported for the county. In this study, a collection of nearly 50 lichens were acquired in 2016 and 2017 from Lawrence County. Seventeen lichen species are reported as new to the county. This study demonstrates that lichen diversity in Lawrence County is underestimated. Keywords: Lichens, Pennsylvania, floristics, Lawrence County.

Chileans living in urban areas are exposed to several air pollutants, namely to a mean annual concentration of atmospheric PM2.5 (>40 µg m−3 year−1) that exceeds two times the level established by legislation in both Chile and the European Union and four times higher than the recommended by the World Health Organization for good air quality. The evaluation of air pollution, namely particulate pollution, in urban areas is performed by air quality monitoring stations. These, are not sufficiently distributed in space to cover all areas with high spatial resolution, needed for a good assessment of the exact human exposure. In this context, lichen diversity studies could fill the gap of increasing air quality spatial resolution in areas not covered by monitoring stations. We aim at using taxonomic (species richness and abundance) and trait-based epiphytic lichen diversity (growth form) to evaluate the impact of air pollution levels in Chilean urban environments. For that, lichen diversity was evaluated in three background areas, seven centres of various Chilean cities and their peri-urban zones. Though trait-based metrics responded negatively to air pollution, lichen abundance was the best metrics (index of lichen diversity), being negatively associated (r = −0.89; p < 0.001) with the number of days per year that particles exceeded the mean annual level established by legislation (>20 µg m−3 year−1). This suggested that the main source of changes in lichen diversity in urban areas of Chile is particulate material or other associated pollutants. These findings show that in high levels of pollution, total lichen diversity can be used to track particulate material pollution above the recommended levels, providing data for areas without monitoring stations. This information can then be used to select new areas for monitoring stations, or to evaluate the potential health effects of the population living in these areas.

Since methylmercury is a highly toxic compound, there is undoubtedly a need for the monitoring of methylmercury in the ecosystem. However, its isolation from the organic matrix using an appropriate analytical procedure and sensitive detection technique are necessary due to trace levels of methylmercury in biomonitors. This study focuses on the determination of methylmercury in plant matrices by means of GC-AFS. The developed extraction procedure is based on the enzymatic hydrolysis of the matrix by cellulase, followed by the extraction of methylmercury in hydrochloric acid and the extraction of derivatized methylmercury into the organic phase. The limit of detection of methylmercury in environmental samples was 4 μg kg−1. The method demonstrated sufficient precision, accuracy, and repeatability with respect to the determination of methylmercury in cryptogams. High contents of methylmercury (up to 60.9 ± 4.4 μg kg−1) were determined in cyanobacterial mats from James Ross Island (Antarctic Peninsula). Thus, freshwater lakes and wetlands in Antarctica can be sources of methylmercury for the local ecosystem. Keywords: Methylmercury; Cyanobacterium; Alga; Lichen; GC-AFS.

The improved bactericidal activity of new composites for wound dressing prototypes represents an important strategy for development of more efficient devices that make use of synergistic interaction between components. The doping level of polyaniline represents a critical parameter for its corresponding biologic activity. In this work, it is explored the doping effect of usnic acid on undoped polyaniline, that introduces important advantages namely, improved bactericidal activity of polyaniline and the anti-biofilm properties of lichen derivative. The deposition of the resulting material on polyurethane foam potentializes its applicability as wound dressing, characterizing a new platform for application against Escherichia coli and Staphylococcus aureus.

(Cyanobacteria): two novel cyanobacterial constituents isolated from a tripartite lichen of headstones. - Journal of Phycology, 54: 224–233.|
Cyanolichens are an assembl age of fungi and cyanobacteria from diverse, cosmopolitan habitats. Typically composed of a single species of cyanobacterium, with or without another eukaryotic alga, here we present two novel cyanobionts isolated from an undescribed tripartite lichen. This endolithic lichen was isolated from a granite cemetery tombstone from Jacksonville, FL, and contains two potentially nitrogen-ﬁxing cyanobionts. Employing a total evidence approach, we characterized the cyanobionts using molecular (the 16S rDNA and ITS gene region), morpho logical, and ecological data. Phylogenetic analyses revealed two novel taxa: Bra silonema lichenoides and Chroococcidiopsis lichenoides, both of which fell within well-supported clades. To our knowledge, this represents the ﬁrst instance of a tripartite lichen with two cyanobacterial and no eukaryotic members. These types of lichens may well represent an unexplored reservoir of cyanobacterial diversity. The speciﬁc epithets are proposed under the provisions of the International Code of Nomenclature for algae, fungi, and plants.

Symbioses among co-evolving taxa are often marked by genome reductions such as a loss of protein-coding genes in at least one of the partners as a means of reducing redundancy or intergenomic conflict. To explore this phenomenon in an iconic yet under-studied group of obligate symbiotic organisms, mitochondrial genomes of 22 newly sequenced and annotated species of lichenized fungi were compared to 167 mitochondrial genomes of nonlichenized fungi. Our results demonstrate the first broad-scale loss of atp9 from mitochondria of lichenized fungi. Despite key func- tions in mitochondrial energy production, we show that atp9 has been indepen- dently lost in three different lineages spanning 10 of the 22 studied species. A search for predicted, functional copies of atp9 among genomes of other symbionts involved in each lichen revealed the full-length, presumably functional copies of atp9 in either the photosynthetic algal partner or in other symbiotic fungi in all 10 instances. Together, these data yield evidence of an obligate symbiotic relationship in which core genomic processes have been streamlined, likely due to co-evolution. Keywords: fungi, genome reduction, lichen, mitochondrial evolution, symbiosis.

This work deals with analysis and modelling of the radionuclides 210Pb and210Po in the food-chain lichenreindeer- man in addition to 210Po and 137Cs in top predators. By using the methods of Partial Least Square Regression (PLSR) the atmospheric deposition of 210Pb and 210Po is predicted at the sample locations. Dynamic modelling of the activity concentration with differential equations is fitted to the sample data. Reindeer lichen consumption, gastrointestinal absorption, organ distribution and elimination is derived from information in the literature. Dynamic modelling of transfer of 210Pb and 210Po to reindeer meat, liver and bone from lichen consumption, fitted well with data from Sweden and Finland from 1966 to 1971. The activity concentration of 210Pb in the skeleton in man is modelled by using the results of studying the kinetics of lead in skeleton and blood in lead-workers after end of occupational exposure. The result of modelling 210Pb and 210Po activity in skeleton matched well with concentrations of 210Pb and 210Po in teeth from reindeer-breeders and autopsy bone samples in Finland. The results of 210Po and 137Cs in different tissues of wolf, wolverine and lynx previously published, are analysed with multivariate data processing methods such as Principal Component Analysis PCA, and modelled with the method of Projection to Latent Structures, PLS, or Partial Least Square Regression PLSR.

Nyl. and its protective effect on alveolar epithelial cells from Pb2+-induced oxidative damage. - International Journal of Biological Macromolecules, 112: 101–109.|
Air pollution is a serious global health problem nowadays. So, it is an emergency to pay sufficient attention to treat and prevent the diseases caused by air pollution, especially respiratory disease and lung damage. Cladina rangiferina (L.) Nyl. is an edible lichen that has been used inmedicinal diets to treat respiratory and other diseases for over 500 years. In this study, a water-soluble polysaccharide, CRWP-P, was obtained from C. rangiferina by hot-water extraction, freeze-thawing separation, and Fehling reagent purification. Structural analysis showed that CRWP-P is a linear α-(1 → 3),(1 → 4)-D-glucan without branches. Its Mw was determined to be 1.05 × 105 Da. Its (1,3)-α-D-glucopyranosyl: (1,4)-α-D-glucopyranosyl ratio is approximately 1:2. Antioxidant activity assay showed that C. rangiferina polysaccharides, especially CRWP-P, had appreciable DPPH radical-scavenging activity and reducing power. Notably, they could effectively decrease cell breakdown and ROS generation, inhibit lipid peroxidation, increase key antioxidase activity, and promote glutathione redox cycling in Pb2+-oxidative injured A549 alveolar epitheliumcells.Overall, the results of this study indicated that C. rangiferina polysaccharides, especially CRWP-P, have the potential to be natural antioxidants for the treatment of lung oxidative damage induced by lead of air pollutants. Keywords: Cladina rangiferina (L.) Nyl.; α-Glucan; Antioxidant aktivity; Alveolar epithelium cell; Pb2+-oxidative toxicity protection.

Everniastrum cirrhatum is a medicinally important lichen used in Ayurvedic and Unani systems of medicine. In the present study, DAMD and ISSR methods were used to estimate the genetic variation and population structure of E. cirrhatum collected from different geographical regions of India. Four DAMD and ten ISSR primers detected 42 and 110 polymorphic bands and accounted for 95.65 and 94.24% polymorphisms, respectively. Cumulative band data generated for DAMD and ISSR markers resulted into 94.95% polymorphism across all the accessions of E. cirrhatum. The UPGMA dendrogram showed two major clusters. The clustering pattern in the UPGMA dendrogram revealed that the groupings are largely in congruence with the geographical distribution of the accessions. Clustering patterns in STRUCTURE revealed that geographical diversity is perfectly in congruence with the genetic diversity. The clustering pattern in STRUCTURE was also supported by PCoA. Mantel test for matrix correlation showed a weak but positive correlation between genetic and geographical distance. The hierarchical analysis of molecular variance revealed that maximum percentage of variation was found within a population (57%), followed by among regions (28%) and among populations (15%). The present study provides significant insight into the genetic variability and population structure of E. cirrhatum. Understanding population structure would provide baseline information for developing its sustainable management strategies. It would also be important to conserve populations of E. cirrhatum in different localities of the Himalayan regions to prevent population decline caused by anthropogenic and environmental stochastic effects.

(2018): Renaissance of a rural artifact in a city with a million people: biodiversity responses to an agro-forestry restoration in a large urban traditional fruit orchard. - Urban Ecosystems, 21: 263–270.|
The rural landscapes surrounding large cities are rapidly becoming incorporated into the urban environment. The most conspicuous changes involve green spaces, such as former agro-forestry systems like fruit orchards. In this paper, we assess the influence on biodiversity of restoring a large urban traditional fruit orchard as reflected by six selected taxa: plants, lichens, butterflies, beetles, orthopteroids and birds. The study was performed in Prague, which is the capital city of the Czech Republic and has more than a million inhabitants. We studied the effect of orchard renewal in 45 patches (15 for birds and 30 for other taxa). The majority of taxa responded positively to the restoration. The restoration had a significant positive effect on the species richness of lichens, butterflies and beetles. All taxa showed significantly altered species compositions, and the number of red-listed species increased. Orchards have a high potential for multifunctional use. Orchards are productive agro-forestry systems and host numerous possible human activities. Therefore, orchard restoration also has a social aspect. Moreover, our research in this artificial ecosystem revealed that its restoration increased the biodiversity and conservation potential of the associated areas.

We report the production of the perylenequinone pigment elsinochrome A in aposymbiotic culture of the mycobiont of the crustose epiphytic lichen Graphis elongata Zenker (Lecanoromycetes), collected in Argentina (Buenos Aires). The substance was not detected in the lichenized thallus (using HPLC techniques) and is otherwise only known from one unrelated lichen and a few genera of non-lichenized, plant-pathogenic fungi in the class Dothideomycetes. The phylogenetic affinities of the lichen mycobiont and the cultured fungus were confirmed using DNA sequence data of the mitochondrial small subunit rDNA (mtSSU), which place the lichen fungus into the Allographa clade within Graphidaceae. The mycobiont pigment was purified and characterized by spectroscopic methods. This is the first case where a rare pigment, otherwise known from non-lichenized, plant-pathogenic fungi, is produced in aposymbiotic culture of a lichen mycobiont, while, at the same time, being absent from the lichen thallus itself. Based on this finding, we discuss the previously postulated hypothesis that lichen mycobionts maintain secondary metabolic pathways of non-lichenized ancestors in their genome, while gene expression and production of metabolites is suppressed in the lichenized state due to toxicity to the photobiont.

[Translated from the Russian original published in Khimiya Prirodnykh Soedinenii, No. 2, March–April, 2018, pp. 306–307.] The goal of the research was to determine by HPLC the contents of phenolic metabolites in Cladonia lichens growing under the contrasting climatic conditions of Yakutia and Belarus. The study included 52 herbarium specimens belonging to 15 species of Cladonia lichens collected in Yakutia and preserved in the herbarium of the Institute of Biological Problems of the Cryolithozone, SB, RAS (SASY) and in Belarus and preserved in the herbarium of V. F. Kuprevich Institute of Experimental Botany, NASB (MSK). Herbarium specimens of lichens were designated for storage in 1956–2016. The studied lichens contained eight main phenolic metabolites from the lichen compound group including five that were depsides (atranorin and perlatolic, barbatic, squamatic, and thamnolic acids); one, a depsidone (fumarprotocetraric acid); and two, dibenzofurans (usnic and isousnic acids). The constituent compositions of most studied lichens agreed with those in the literature . Lichens C. arbuscula, C. cariosa, C. mitis, and C. stellaris collected in Yakutia and Belarus were shown to have component compositions belonging to the same known chemotypes that are broadly distributed in northern populations of these species. However, lichens C. coniocraea and C. uncialis represented new and previously unknown chemotypes (Table 1). C. uncialis contained thamnolic (2) and not squamatic acid (3) only in samples from Belarus. However, the C. coniocraea chemotype containing the main component barbatic (4) and not fumarprotocetraric acid (1) was characteristic of both study sites.

In this work, we aimed to develop stable usnic acid (UA)-conjugated superparamagnetic iron oxide nanoparticles (SPIONs) as a potential drug carrier for in vitro analysis of MCF-7 (breast cancer cell line), HeLa (cervix cancer cell line), L929 (mouse fibroblast cell line), U87 (glioblastoma cell line, brain cancer), and A549 (human lung cancer cell line) cell lines. SPIONs were synthesized via the polyol method and functionalized with APTES using the St¨ober method. Carboxylated polyethylene glycol (PEG-COOH), folic acid (FA), and carboxylated luteolin (CL) were conjugated on the surface via a carboxylic/ amine group using the nanoprecipitation method, respectively. X-ray powder diffraction analysis confirmed the purity of the product with crystallite size of around 11 nm. Fourier-transformed infrared spectrophotometer (FT-IR) analyses explained the conjugation of all functional groups to the surface of SPIONs. The percentages of inorganic and organic content in the products were investigated via thermal gravimetric analyzer (TGA). For morphological analysis, a transmission electron microscope (TEM) was used. The superparamagnetic property of the product was also confirmed by vibrating sample magnetometer (VSM).

Raised peat bogs harbor unique vegetation types in specific hydrological conditions. Environmental controls of peat bog vegetation are relatively well known for the boreal zone, while in the European boreonemoral zone healthy raised bogs are nowadays very rare. By contrast, Latvia, located in the transition zone between the nemoral and the boreal biomes, still has a large number of active raised bogs. The aim of the present study was to characterize the environmental controls on raised bog vegetation structure, species composition and ecology in Latvia. The study includes 17 raised bogs, where vascular plants, bryophytes and lichens were recorded in 480 sample plots and related to environmental variables (microtopography, litter cover, electric conductivity, pH, and macroelements Na, K, Ca, Mg and P in bog surface waters). The factor best explaining total species richness and composition was microtopography, which also affected most other explanatory factors. Thereby total species richness and cover were highest on hummocks. However, the importance and direction of the effects of microtopography and the other factors differed between vegetation groups. When disregarding microtopography, species composition was most strongly correlated with alkaline ions and litter cover and for bryophytes also with vascular plant cover. The present study is the first widescale study in Latvia relating raised bog vegetation to environmental conditions. Keywords: Microtopography. Peatbogs . Sphagnum . Vegetation.

Detailed morphological studies and inference from molecular phylogenetic analyses, based on maximum likelihood and Bayesian analyses of single gene locus (ITS), clearly indicate that the new species is a member of the recently introduced genus Palicella. Palicella lueckingii is most closely related to P. glaucopa, but clearly differs in having smaller ascospores, comparatively thicker thallus, epruinose apothecia, lack of oil droplets inside of exciple and presence of thiophanic acid as a major metabolite. Keywords: biodiversity, Chile, ITS, Lecanoromycetes, Lecidea s. lat., new species, phylogeny.

In the course of a multi-taxon biodiversity inventory for the island of St. Eustatius, lichens were collected from 11 plots representing different vegetation types. From these collections, 126 lichen species are reported, 54 of which are new reports for St. Eustatius. Most species could be identified to species level based on morphological and chemical characters. In a few cases, mtSSU DNA sequences were generated for a preliminary molecular identification and future phylogenetic studies. In total, 263 identified lichen species are currently known from St. Eustatius, as well as some additional genera with yet unidentified species and lichenicolous fungi. Keywords: Biodiversity inventory, lichens, mtSSU, St. Eustatius.

Allocetraria madreporiformis is a small, finger-like, fruticose lichen with isolated occurrences in the inner fiord section of the long, straight fiord Wijdefjorden in Svalbard. Several new localities are added and mapped here, and we show that the species is confined to exclusive high-arctic steppe habitats on fine-textured, moderately alkaline soil, exposed to wind erosion and aeolian transport of silt and sand. It avoids the most saline steppes and adjacent tundra areas, as indicated by numerous pH samples of mineral soils from sites with and without occurrences of A. madreporiformis. In this open habitat, all otherwise common arctic-alpine fruticose lichen species were absent or extremely rare, and a cryptogamic cover was very depauperate. On Svalbard, this species is an exclusive character species of the steppe areas in Inner Wijdefjorden National Park. The genus Allocetraria is strongly centred in the Sino-Himalayan area. It is discussed here that it probably evolved as a response to the very extensive new habitats formed during a series of Qinghai-Tibetan Plateau uplift and orogeny events taking place 25–1.6 Ma. This and other aspects affecting current classification alternatives of cetrarioid lichens are also discussed. The habitat preferences of A. madreporiformis appear to have been largely defined by the conditions of its probable area of origin in steppe-like habitats of the northern part of the Qinghai-Tibetan Plateau.

Lobaria peltigera forms a conspicuous lichen found in well-preserved, neotropical montane rain forests, being the name-giving species of the L. peltigera group, a distinctive, monophyletic entity recently segregated in the genus Yoshimuriella. Unfortunately, the original basionym of this name, Sticta peltigera Delise, is illegitimate, since the protologue includes the type of the name that should have been adopted. To remedy this situation and retain the epithet peltigera, we adopt this epithet in the combination Lobaria peltigera Vain. as the name of a new species. Vainio's work was the foundation for a modern taxonomy of many tropical lichens, including tropical species of Lobaria s.lat., and his herbarium in Turku is a primary reference for tropical lichen research. His concept of L. peltigera corresponds precisely to the modern circumscription of this taxon and his material in TUR-Vainio, distributed in his exsiccate Lichenes Brasilienses Exsiccati, is properly designated as lectotype. Based on this, we propose the new combination Yoshimuriella peltigera (Vain.) Lücking & Moncada.

mating types, Xanthoria, genetics, mat locus, α-box fragment, α-domain, hmg box, heterothallic, homothallic, idiomorph, single spore isolates Authors used Xanthoria parietina, X. polycarpa, X. flammea and X. elegans. The complete MAT locus, containing one ORF (MAT-2-1) coding for a truncated HMG-box protein, and two partial flanking genes, were cloned by screening a genomic lambda phage library of the homothallic X. parietina. The occurrence of mating-type genes in eight single spore isolates derived from one ascus was studied with a PCR assay. In the homothallic X. parietina a HMG fragment, but no α-box fragment was found in all isolates, whereas in X. elegans, another homothallic species, all tested isolates contained a fragment of both idiomorphs. Conversely, isolates of the heterothallic X. polycarpa contained either a HMG or an α-box fragment, but never both

Investigation of the chemical constituents of the lichen Usnea baileyi (Stirt.) Zahlbr led to the isolation of a new dimeric xanthone, bailexanthone (1), and a novel depsidone, bailesidone (2), along with twenty-five known metabolites (3–27). Their structures were established by means of extensive spectroscopic analysis and comparison with data reported in the literatures. Compound 1 derives from secalonic acid scaffold with C-8/8′ reduction and compound 2 represents the first example of menegazziaic acid derivative with an unprecedented B-ring moiety. Two new compounds 1–2 were evaluated for their cytotoxic activities against A549 (human lung carcinoma) and HT29 (human colorectal adenocarcinoma) cell lines. All of them showed weak or no activity against two cell lines. Keywords: Lichen; Usnea baileyi; Depsidones; Dimeric xanthone; Cytotoxicity.

The competitive behavior of divalent heavy metals (Cd, Cr, Pb, Zn) during cation uptake was investigated in the foliose lichen Xanthoria parietina. Lichen thalli were incubated with solutions containing 10 and 100 μM of CdCl2, CuCl2, and ZnCl2 as well as 5 and 50 μM of Pb(NO3)2, tested individually and in combination (Cd2++Cu2++Pb2++Zn2+). The analysis of molar concentrations suggests that a competition between cations for binding sites in X. parietina does exist. The decrease in net uptake between single and mixed solutions ranged between 14 and 29% at the lowest concentration and between 38 and 68% at the highest concentration. Furthermore, the uptake was proportionally lower for richer solutions. Each metal may behave differently when uptook: some (toxic elements) are preferentially stored at extracellular level (Cd, Pb), while others (micro-nutrients) are also present at intracellular level (Cu and Zn). The proportion between extracellular and total content changed for those elements accumulated also at intracellular level (Cu and Zn), while for Cd and Pb almost all the uptake occurred by passive mechanisms mainly at extracellular binding sites. The competition between metals for binding sites in the lichen surface entails that bioaccumulation data might result in an underestimation of some element levels measured in biomonitoring studies. Keywords: Bioaccumulation; Heavy metals; Ionic uptake; Xanthoria parietina.

The Tibetan Plateau (TP) is a huge area and rarely affected by human activity, and is regarded as one of the most remote regions on the earth. Many studies about the long-range atmospheric transport (LRAT) of semi-volatile organic compounds (SVOCs) were conducted in southern and central TP. However, there are very limited studies focused on PAHs in the western TP and the concentrations profiles, distribution and its controlling factors in this area remains unclear. Thus, to explore this knowledge gap, 37 surface soil samples and 23 lichen samples were collected and analyzed for PAHs. The total concentration of 16 US EPA's priority PAHs (∑16PAHs) in western TP ranges 14.4–59.5 ng/g and 38.0–133 ng/g dry weight (dw) with a mean value of 30.8 and 84.6 ng/g dw in soil and lichen, respectively, which is lower than the concentrations in most remote areas worldwide. In the western TP, low molecular weight PAHs (2–3 rings) are dominant (occupied 77.4% and 87.9% on average in soil and lichen, respectively), implying a significant contribution of LRAT in this area. The significant linear correlations (R2 = 0.372–0.627, p < 0.05) between longitude and soil concentration suggest a strong impact of the westerly wind on the distribution of PAHs in soil. In addition, the concentration ratio of lichen/soil (L/S) was found to linearly increase with the increasing log KOA of individual PAH, suggesting lichen has a strong ability in filtering more lipophilic airborne pollutants in western TP. Keywords: PAHs; Tibetan Plateau; Long-range atmospheric transport (LRAT); Alpine region; Mountain.

Ach. analysed by simultaneous measurements of the kinetics of prompt fluorescence, delayed fluorescence and modulated 820 nm reflection. - Journal of Luminescence, 198: 302–308.|
Simultaneous in vivo measurements of prompt fluorescence (PF), delayed fluorescence (DF) and modulated reflection (MR) at 820-nm were used to assess effect of short desiccation period (4.5 h) on Parmelina tiliacea lichen. The two performance indexes (PIABS and PItotal) as a measure of an overall photosynthetic thalli performance showed a negative effect of desiccation treatment on photosynthetic activity. The maximal intensity of PF and DF recorded during desiccation treatment decreased and at 4.5 h desiccation time Parmelina tiliacea thalli loss their variable fluorescence and DF amplitude. This loss of variable fluorescence was due to an increase in inactive reaction centers and a limitation of electron donation on the donor side of photosystem II (PSII) that caused a down-regulation of electron transport chain at the PSII level. However, the efficiency with which an electron can move from the reduced intersystem electron acceptors to the PSI end electron acceptors was less affect by desiccation treatment. In respect to MR change, re-reduction kinetics of the primary electron donors of photosystems I (P700) and plastocyanin (PC) in desiccated thalli seem to be faster, their amplitudes gradually decrease and a disconnection between the two photosystem (PSII and PSI) were observed. These responses allow to Parmelina tiliacea lichen a photoprotection mechanism from the excess light excitation.

(2018): Fungal communities associated with Evernia prunastri, Ramalina fastigiata and Pleurosticta acetabulum: Three epiphytic lichens potentially active against Candida biofilms. - Microbiological Research, 211: 1–12.|
Fungal communities associated to three epiphytic lichens active against Candida, were investigated using culture-based methods We hypothetized that associated fungi would contribute to lichens activities. The ability of specific fungi to grow inside or outside lichens was investigated. To detect biogenesis pathways involved in the production of secondary metabolites, genes coding for nonribosomal peptide synthetase (NRPS) and polyketide synthase I (PKS I) were screened by PCR from fungal DNA extracts. Both endo and epilichenic communities were isolated from two fructicose (Evernia prunastri and Ramalina fastigiata) and one foliose (Pleurosticta acetabulum) lichens. A total of 86 endolichenic and 114 epilichenic isolates were obtained, corresponding to 18 and 24 phylogenetic groups respectively suggesting a wide diversity of fungi. The communities and the species richness were distinct between the three lichens which hosted potentially new fungal species. Additionally, the endo- and epilichenic communities differed in their composition: Sordariomycetes were particularly abundant among endolichenic fungi and Dothideomycetes among epilichenic fungi. Only a few fungi colonized both habitats, such as S. fimicola, Cladosporium sp1 and Botrytis cinerea. Interestingly, Nemania serpens (with several genotypes) was the most abundant endolichenic fungus (53% of isolates) and was shared by the three lichens. Finally, 12 out of 36 phylogenetic groups revealed the presence of genes coding for nonribosomal peptide synthetase (NRPs) and polyketide synthase I (PKS I). This study shows that common lichens are reservoirs of diverse fungal communities, which could potentially contribute to global activity of the lichen and, therefore, deserve to be isolated for further chemical studies. Keywords: Endolichenic; Epilichenic fungi; Barcoding; Sordariomycetes; Xylariaceae; NRPs and PKS I genes.

We examined taxonomic composition of fungal communities in Picea abies log bark using next generation sequencing. Three successional stages along gradients of log attributes were identified. In the initial stage, the communities were composed by yeasts, plant pathogens and cosmopolitan saprotrophic fungi with broad substrate utilization. In the intermediate stage, bark was colonized mainly by saprotrophs common in decaying wood, symbionts of epixylic plants and nematode-trapping fungi. The final stage was characterized by the dominance of mycorrhizal fungi. Wood-decaying fungi occurred in all stages. However, their sporadic appearance in bark samples suggests that they are not essential for bark decomposition. Our results provide an insight into the hidden diversity of wood-inhabiting communities - fungal communities, associated with decomposition of bark as a component of coarse woody debris. p. 5: "The OTU richness of lichenized fungi was negatively related to bark moisture content."; p. 8: "In the third successional group, we detected the highest abundance of mycorrhizal fungi and almost complete disappearance of lichenized and pathogenic fungi."

This paper includes three aspects. First, a new concept of classification has been proposed, i.e. systematic biology of lichenized fungi with three systems of storage and retrieval is a bridge between biodiversity in the nature and exploration of lichen resources. Second, the symplesiomorphic analyses based on genotype together with phenotype data have solved the generic classification in the Umbilicariaceae, which has not been solved by the analyses of molecular systematics. Third, marginal species have been found in genus differentiation of the Umbilicariaceae by symplesiomorphic analyses. The concept of the marginal species is discussed. The results show, the family Umbilicariaceae and their genera are monophyletic group respectively. Key words： Lasallia; Umbilicaria; full-length LSU rDNA; marginal species; monophyletic group.

Premise of the study: Changing climates are expected to affect the abundance and distribution of global vegetation, especially plants and lichens with an epiphytic lifestyle and direct exposure to atmospheric variation. The study of epiphytes could improve understanding of biological responses to climatic changes, but only if the conditions that elicit physiological performance changes are clearly defined. Methods: We evaluated individual growth performance of the epiphytic lichen Evernia mesomorpha, an iconic boreal forest indicator species, in the first year of a decade-long experiment featuring whole-ecosystem warming and drying. Field experimental enclosures were located near the southern edge of the species’ range. Key results: Mean annual biomass growth of Evernia significantly declined 6 percentage points for every +1°C of experimental warming after accounting for interactions with atmospheric drying. Mean annual biomass growth was 14% in ambient treatments, 2% in unheated control treatments, and −9% to −19% (decreases) in energy-added treatments ranging from +2.25 to +9.00°C above ambient temperatures. Warming-induced biomass losses among persistent individuals were suggestive evidence of an extinction debt that could precede further local mortality events. Conclusions: Changing patterns of warming and drying would decrease or reverse Evernia growth at its southern range margins, with potential consequences for the maintenance of local and regional populations. Negative carbon balances among persisting individuals could physiologically commit these epiphytes to local extinction. Our findings illuminate the processes underlying local extinctions of epiphytes and suggest broader consequences for range shrinkage if dispersal and recruitment rates cannot keep pace. Key words: biomass accumulation; boreal forests; carbon balance; carbon dioxide enrichment; climate change experiment; epiphytes; extinction debt; growth rates; lichens; whole-ecosystem warming.

We explored the fine scale patterns of populations of the lichen Lobaria pulmonaria in its most suitable habitats across Italy, accounting for different developmental stages as well as for a set of biotic and abiotic descriptors. Results revealed that the tree-level probability of occurrence of the species is influenced by an interplay between the forest habitat type and some abiotic and biotic factors whose interactive effects vary during the life cycle of the lichen. Moreover, results indicated that oak (Quercus sp.pl.)-dominated forests provide more suitable habitat conditions for L. pulmonaria than montane mixed forests, with chestnut (Castanea sativa) forests in an intermediate position. The effect of habitat was significant only for adult thalli while the early life stages of the lichen were habitat-independent and were strictly associated with tree-level factors. A positive relationship between bryophyte cover and juvenile thalli was found.

|29106||Lindgren P.M.F. & Sullivan T.P. (2018): Influence of repeated fertilization on forage production for native mammalian herbivores in young lodgepole pine forests. - Forest Ecology and Management, 417: 295–280.|
Stand thinning and fertilization are silvicultural practices designed to enhance wood and biomass production. Applications of nitrogen-based fertilizers make nutrients potentially available to all trees, plants, and wildlife in a given forest ecosystem, and therefore may affect productivity of forage plants for native mammalian herbivores. Species associated with areas of forest fertilization in temperate and boreal zones of North America include mule deer (Odocoileus hemionus), elk (Cervus elaphus), moose (Alces alces), and woodland caribou (Rangifer tarandus), snowshoe hare (Lepus americanus), and several species of voles. Impacts of fertilization on forest plant species may have important consequences for the nutrition, cover, and consequent survival of these herbivores, particularly in winter. This study tested the hypothesis (H1) that large-scale repeated fertilization, up to 20 years after the onset of treatments, would enhance the biomass production of forage plants, particularly grass, forb, shrub and tree species for native mammalian herbivores. A secondary hypothesis (H2) predicted that mosses and terrestrial lichens would decline as part of the ground vegetation in fertilized stands. Study areas were located in lodgepole pine (Pinus contorta var. latifolia) stands near Summerland, Kelowna, and Williams Lake in south-central British Columbia, Canada. Each study area had eight replicate stands: four unfertilized, and four fertilized five times at 2-year intervals. Mean biomass of total grasses responded dramatically starting in the first year after fertilization. Total forbs and herbs also followed this pattern, although not to a significant degree until after the second and third applications of fertilizer. All of the dominant grasses and forbs serve as summer forage for mule deer, moose, elk, and woodland caribou. Fireweed (Epilobium angustifolium), a preferred forage for mule deer, increased in fertilized stands. Grasses and dominant herbs in fertilized stands provide excellent forage and cover habitat for snowshoe hares and Microtus voles. Mean biomass of total shrubs was not affected by fertilization. However, saskatoon berry (Amelanchier alnifolia), prickly rose (Rosa acicularis), and red raspberry (Rubus idaeus) increased significantly in biomass in fertilized stands. Willow (Salix spp.) also increased in biomass, but was variable across treatment stands. Snowshoe hares respond favourably to enhanced shrub growth for food and cover in fertilized stands. All of these shrubs are readily eaten by deer, moose, and elk, and their structural attributes provide security and thermal cover. Mean biomass of understory Douglas-fir (Pseudotsuga menziesii) responded positively to fertilization, but subalpine fir (Abies lasiocarpa) and the three deciduous tree species did not. Dwarf shrubs such as kinnikinnick (Arctostaphylos uva-ursi), twinflower (Linnaea borealis), and dwarf blueberry (Vaccinium caespitosum) declined in fertilized stands. Thus, H1 was partially supported for some species. Increasing cover of grasses and nitrophilous herbs, and canopy cover from rapidly growing crop trees, in fertilized stands may have contributed to the decline of some dwarf shrubs. Mean crown volume index of total mosses and terrestrial lichens declined significantly in fertilized stands, thereby supporting H2. Mean biomass of total grasses (increase), R. acicularis (increase), and V. caespitosum (decline) were significantly affected after one application of fertilizer. Repeated applications of fertilizer may enhance biomass of some additional forage forbs and shrubs, but reduce biomass of some dwarf shrubs, mosses, and lichens.
|29105||Payette S. & Delwaide A. (2018): Tamm review: The North-American lichen woodland. - Forest Ecology and Management, 417: 167–183.|
The lichen woodland (LW) is an open-crown subarctic forest distributed principally in North America where it extends from Newfoundland in Atlantic Canada to the Yukon and Alaska. It is the main tree ecosystem of the LW zone north of the closed-crown boreal forest zone, and south of the forest-tundra zone where its cover diminishes progressively toward the Arctic tree line. Growth and development of LWs are closely dependent on dry-mesic, nutrient-poor podzolic soil environments largely distributed on the Canadian Precambrian Shield. The sunexposed open structure and dominance of lichen species on the dry-mesic soils of LWs determine many of their functions. A diversified cryptogamic flora is thriving in LWs due to reduced competition from vascular plants unable to grow and survive on dry, nutrient-poor soils. Because of the reduced greenhouse effect caused by the open structure and dominance of pale-color lichen mats inducing a greater albedo, LWs exerts a negative microclimatic impact on the environment culminating in the reduction of the frost-free growth season and increase and intensity of frost events. A suite of common, often recurrent, sometime compounding, fine- and large-scale disturbances (including climate change) activates the successional dynamics of LWs and also their historical and present expansion and contraction across the boreal biome. Post-disturbance chronosequences induced by fire, wind and caribou trampling and grazing are producing similar seral communities converging toward the selfmaintenance of the LW ecosystem. Long-term succession in southernmost LW sites possibly converges toward the closing of tree canopy and recovery of closed-crown conifer forests (CCCF) in absence of fire. The creation of LW occurred repeatedly during the late Holocene, as well as its extirpation from the northernmost sites (foresttundra zone) with wildfire as the principal triggering mechanism. LWs are presently unable to transgress the tree line, except for minor advances in small confined sites. Current evidence of the dual distribution of LWs and CCCF in eastern Canada shows that the LW zone is expanding southward into the CCCF zone, where compound disturbances associated with epidemics followed by small to extensive fires are transforming dense forest stands to LWs, a process most likely independent of climate. In terms of ecosystem management, there are concerns about the maintenance of the southernmost LWs within the CCCF zone as poor carbon sinks. Projects involving LW plantation sites in the CCCF zone in eastern Canada are proposed to offset the increased emission of atmospheric gases and thus mitigate climate change.

Short-term (24 h) responses of Cladonia arbuscula subsp. mitis (formerly known as Cladina and this name is used to distinguish the tested species) and Cladonia furcata to nickel (Ni2+) excess (10 or 100 μM) were compared. Cladonia accumulated more Ni at higher Ni dose (1.717 mg total Ni/g DW), K amount was unaffected and Ca amount decreased in Cladina only. Fluorescence microscopy detection of total/general ROS and hydrogen peroxide showed Ni-stimulated increase in both species being more pronounced in Cladonia and in mycobiont partner mainly. Nitric oxide visualization (diaminonaphthalene staining) also revealed elevation in response to Ni that could contribute to synthesis of protective metabolites: they may include ascorbic acid or reduced glutathione which increased in Ni-exposed Cladina or Cladonia, respectively. Only low content of phytochelatin 2 was detected in Ni-treated Cladonia and the role in Ni chelation is not apparent. Among aliphatic organic acids, content of citric or succinic acid was not or slightly affected by Ni, production of malic acid dropped by ca. 50% in both species and α-ketoglutaric acid showed the opposite behavior in the tested species. Data indicate that even short-term Ni treatments induce metabolic changes and symptoms of oxidative stress in lichens, confirming that nickel is not non-toxic metal as frequently visible from standard biochemical assays of basic physiology. Ascorbic acid and GSH rather than aliphatic organic acids seem to contribute to Ni tolerance.

Preliminary report on the lichen flora of the Biosphere Reserve Východně Karpaty (NE Slovakia), is presented. In total 208 species is recorded (62 of them belong among threatened). Several species very rare in other parts of Slovakia were found: Lecanora cinereofusca, Thelotremalepadinum, Lobariapulmonaria, Normandinapulchella Mencgaiziaterebrata Gyalectaflotowii, G. ulmi. Though suitable conditions for development of epiphytic and epixylic lichens (132 taxa) are still present in the Reserve, decrease of sensitive indicators of natural mountain forests is evident.

Myrmecia israeliensis has been traditionally considered as a green coccoid free–living microalga. This microalga was previously suggested as the primary phycobiont in the lichens Placidium spp., Heteroplacidium spp., and Psora decipiens. However, due to the absence of ITS rDNA sequences (barcode information) published along with these investigations, the symbiotic nature of M. israeliensis might be confirmed by using the DNA barcoding and different microscopic examinations both in the symbiotic state and in culture. The aim of this study was to settle the presence of M. israeliensis as the primary microalga in squamulose lichens growing in terricolous communities (Psora spp., Placidium spp. and Claviscidium spp.) in 32 localities within European and Canary Island ecosystems by using both molecular and ultrastructural techniques. The lichen–forming fungi were identified using ITS rDNA as a barcode, and in the case of P. decipiens specimens, the mycobiont analyses showed an unexpected variability. Phycobiont phylogenetic analyses were made using both chloroplast (LSU rDNA) and nuclear (ITS rDNA) molecular markers. Our results proved that M. israeliensis is the primary symbiotic microalga in all the chosen and analyzed lichens. In addition, fluorescence microscopy, transmission electron microscopy and scanning electron techniques were used to characterize M. israeliensis. Finally, the presence of this microalga in lichen thalli was verified using different microscopic observations. A combination of different techniques, both molecular and microscopic, allowed for the accurate identification of this symbiotic microalga, beforehand mainly known as free living. Here, we suggest the combination of these techniques to prevent incorrect identification in microalgal lichen studies. Key words: Clavascidium spp., ITS rDNA (barcoding), LSU rDNA, Myrmecia israeliensis, phycobiont, Placidium spp., Psora spp., ultrastructure.

The Mars Desert Research Station is a Mars analog research site located in the desert outside of Hanksville, Utah, U.S.A. Here we present a preliminary checklist of the vascular plant and lichen ﬂora for the station, based on collections made primarily during a twoweek simulated Mars mission in November, 2014. Additionally, we present notes on the endolithic chlorophytes and cyanobacteria, and the identiﬁcation of a fungal genus also based on these collections. Altogether, we recorded 38 vascular plant species from 14 families, 13 lichen species from seven families, six algae taxa including both chlorophytes and cyanobacteria, and one fungal genus from the station and surrounding area. We discuss this ﬂoristic diversity in the context of the ecology of the nearby San Rafael Swell and the desert areas of Wayne and Emery counties in southeastern Utah. Keywords: Analog Research; Floristics; Astrobiology.

The tomb of Cyrus the Great, the most important monument in Pasargadae, has been listed as a world heritage site by UNESCO. Like many other stone monuments, the tomb has been affected by the colonization of microbial communities, especially lichens that were subjected to physical elimination in 2006. In the present study, recolonization of Calogaya sp. PLM8, a crustose lichen and its role in biodeterioration of Cyrus the Great tomb have been evaluated. Calogaya sp. PLM8 commonly colonized on this monument with significant distribution in the different facades. The interface of Calogaya sp. PLM8 with the underlying substrate has been investigated using the periodic acid-Schiff staining, scanning electron microscopy and energy-dispersive spectroscopy techniques. The results showed that both colonization of the lichen on the surface and symbiont cells penetration into the stone had caused extensive physical and chemical biodeterioration of the substrate. Besides the presence of the symbionts in the endolithic niches, other lithobiont microorganisms have been detected inside the stones. The presence of these endolithic microorganisms seems to be conditioned by the presence of the epilithic lichen thallus and its effects on the formation of microenvironments in the colonized stone. The lithobiont communities interact both geophysically and geochemically with the lithic substrate, inducing biodeterioration alteration in the tomb of Cyrus the Great.

[Original Russian Text published in Sverkhkriticheskie Flyuidy. Teoriya i Praktika, 2017, Vol. 12, No. 1, pp. 41–49]. The process of carbon dioxide supercritical fluid extraction (SFE) of secondary metabolites from the lichen of Cladonia genus is studied. The yield of solid extract during SFE with carbon dioxide is significantly higher than during the extraction with acetone, ethanol, and petroleum ether on the Soxhlet apparatus. The maximum content of the target component—usnic acid (UA)—in the extract (91%, yield—2.5% of absolutely dry raw material) is obtained under pressure of 35 MPa, temperature 40°C, and duration of the process of 40 min. Introduction of cosolvents (acetone, ethanol, methylene chloride) to carbon dioxide increases the yield of the target product to 3%. Keywords: supercritical fluid extraction, secondary lichen metabolites, usnic acid, Cladonia lichen genus, parameters of extraction proces.

A method based on ion-pair reversed phase high performance liquid chromatography (HPLC) hyphenated with inductively coupled plasma mass spectrometry (ICP-MS) was developed for arsenic speciation in extract of tree moss. Under the optimal conditions, the limit of detection of eight arsenic species including arsenite (AsIII), arsenate (AsV), monomethylarsonic acid (MMA), dimethylarsonic acid (DMA), trimethylarsinoxide (TMAO), tetramethylarsonium (Tetra), arsenocholine (AsC) and arsenobetaine (AsB) is between 0.04 and 0.07 ng/mL, with a linear range of 0.2 − 500 ng/mL. Three unknown arsenic species (Unk1, Unk2 and Unk3) and six specific arsenic species (AsIII, AsV, DMA, TMAO, Tetra and AsB) were detected in the extract of tree moss. Unk3 was identified as a kind of arsenosugars (2,3-dihydroxypropyl-5-deoxy-5(dimethylarsenoso)furanoside, arsenosugar X) by electrospray ionization quadrupole time-of-flight mass spectrometry (ESI-qTOF-MS).

The objective of this work was to determine the effect of land use on lichen richness and their functional groups in agricultural land. A significant overall effect of land use on the number of species was found. In general, there was a marked dissimilarity with regard to species richness of forest versus non-forest sites. An analysis of some ecological requirements of lichens showed the most apparent differences concerning tolerance to nutrients and acidity value of particular species. Richness of species capable of producing soredia, isidia and reproducing via fragmentation was higher in coniferous forest compared to non-forest habitats (including wooded patches). Functional traits were a more sensitive and more informative index of lichen response to land use intensity compared to species richness.

(2018): Ozone and desiccation tolerance in chlorolichens are intimately connected: a case study based on two species with different ecology. - Environmental Science and Pollution Research, 25: 8089–8103.|
Tropospheric ozone (O3) causes severe damage to many vascular plants but not to lichens. It was recently suggested that this may be due to their high levels of natural defences against the oxidative bursts associated to their fluctuating water content. In this study, the combined effects of watering regime (with or without a daily spray of distilled water), air relative humidity (20 ± 5 vs. 80 ± 5% RH) and O3 (250 vs. 0 ppb, 5 h day−1 for 2 weeks) were monitored in two chlorolichens with different ecology, Parmotrema perlatum and Xanthoria parietina. Modulated chlorophyll a fluorescence (Chl a F), superoxide anion radical (O2 •−) and hydrogen peroxide (H2O2) production, antioxidant content and enzyme activity of the ascorbate/glutathione cycle were measured after exposure and, for Chl a F, after 1 and 2 days of recovery. The species differed in the antioxidant profile (ascorbate was higher in X. parietina, glutathione in P. perlatum), and in the activity of ROS-scavenging enzymes, more intense in the hygrophilous P. perlatum than in the meso-xerophilous X. parietina. O3 slightly modified Chl a F parameters related to the controlled dissipation, with reduction of Fm, Fv/Fm (both species) and ETR (in P. perlatum), and increase in NPQ and qN (in X. parietina). It also influenced, particularly in P. perlatum, the content of H2O2, glutathione (GSH) and oxidized glutathione (GSSG) (but not that of O2 •− and AsA + DHA) and the activity of superoxide dismutase, ascorbate peroxidase and dehydroascorbate reductase. These parameters, however, were more heavily affected by water availability. The hypothesis that lichens are O3-tolerant thanks to the constitutive antioxidant systems, intimately related to their poikilohydric life-style, is thus confirmed. Keywords: Antioxidants Halliwell-Asada cycle Chlorophyll a fluorescence Oxidative stress Poikilohydric organisms.

Microbial biofilms frequently cause the esthetic and biological deterioration of stone monuments. Chichén Itzá, designated as a UNESCO World Heritage Site and as one of the seven new wonders of the world, is one Maya archeological site affected by biofilms. In the present study, we analyzed the biofilms at three different building complexes of Chichén Itzá: the Lower Temple of the Jaguars, the Temple of the Warriors, and Tzompantli. Samples of biofilms and detached rocks were taken from walls with abundant white-, green-, black-, and orange-colored biofilms. The morphology of rock fragments and dust was analyzed by electron and optical microscopy and was structurally characterized by X-ray diffraction. An HCl treatment (5% v/v) was subsequently applied to eliminate carbonates. The morphological analysis evidenced the presence of cyanobacteria, algae, and lichens. Some algae formed small nodules on orange- or black-colored rocks. Lichens were associated with a distinct mineral content on the inner surface of rocks versus on the outer surface. The presence of calcium oxalates such as weddellite (C2CaO4·2H2O) and whewellite (C2CaO4·H2O) and other minerals, including quartz and feldspars, was confirmed by X-ray diffraction. The lichens collected from the Lower Temple of the Jaguars and Tzompantli were therefore confirmed to disintegrate rock surfaces through biomineralization and the formation of oxalate crystals. At sites with greater solar radiation, a higher quantity of weddellite and a lower quantity of whewellite were observed. In conclusion, the establishment of microorganisms on the stone surfaces of Chichén Itzá causes esthetic damage and also leads to the biomineralization of these rock surfaces.

This is the first attempt to provide an overview of the lichen diversity of the Alps, one of the biogegraphically most important and emblematic mountain systems worldwide. The checklist includes all lichenised species, plus a set of non- or doubtfully lichenised taxa frequently treated by lichenologists, excluding nonlichenised lichenicolous fungi. Largely based on recent national or regional checklists, it provides a list of all infrageneric taxa (with synonyms) hitherto reported from the Alps, with data on their distribution in eight countries (Austria, France, Germany, Liechtenstein, Monaco, Italy, Slovenia, Switzerland) and in 42 Operational Geographic Units, mostly corresponding to administrative subdivisions within the countries. Data on the main substrates and on the altitudinal distribution are also provided. A short note points to the main ecological requirements of each taxon and/or to open taxonomic problems. Particularly poorly known taxa are flagged and often provided with a short description, to attract the attention of specialists. The total number of infrageneric taxa is 3,163, including 117 non- or doubtfully lichenised taxa. The richness of the lichen biota fairly well corresponds with the percent of the Alpine area occupied by each country: Austria (2,337 taxa), Italy (2,169), France (2,028), Switzerland (1,835), Germany (1,168), Slovenia (890) and Lichtenstein (152), no lichen having ever been reported from Monaco. The number of poorly known taxa is quite high (604, 19.1% of the total), which indicates that, in spite of the Alps being one of the lichenologically most studied mountain systems worldwide, much work is still needed to reach a satisfactory picture of their real lichen diversity. Thirteen new combinations are proposed in the genera Agonimia, Aspicilia, Bagliettoa, Bellemerea, Carbonea, Lepra, Miriquidica, Polysporina, Protothelenella, Pseudosagedia and Thelidium.

We publish the findings of lichens collected during the survey of selected underexplored sites in the Eastern Slovakia. Alltogether, we report on 241 taxa, of which we collected 211. The list was also supplemented by published information on 30 species, which was scattered in older papers focused on lichen diversity. Eight species were not listed in the latest checklist of lichens of Slovakia or the supplements: Acarospora praeruptorum, Involucropyrenium romeanum, Micarea soralifera, Pyrenopsis sanguinea, Rinodina calcarea, Verrucaria furfuracea, Xanthomendoza huculica and Xanthoria ucrainica. We also briefly comment on other, rarely recorded ones or phytogeographically interesting species (e.g. Agonimia allobata, Bacidia rosella, Caloplaca lucifuga, Hypotrachyna revoluta, Lecania croatica, Parmelina pastillifera, and Solenopsora cesatii). Important collections include other rarely collected species, e.g. Ionaspis lacustris, or Thermutis velutina. Collections of two lichenicolous fungi (Monodictys epilepraria, Tremella lichenicola) and one lichen-allied fungus (Anisomeridium macrocarpum) are reported as well. We also comment on inevitable nomenclatoric changes based on recent biosystematic studies related to Lepraria lobificans (now L. finkii) and Verrucaria deminuta (now V. obfuscans). An importance of update of red list of lichens, along with other groups of organisms is raised. Key words: biodiversity, lichenized fungi, lichenicolous fungi, the Western Carpathians, the Eastern Carpathians.

Phylogenetic analyses using mtSSU and nuITS sequences of Buellia violaceofusca (previously placed in Lecanoromycetes), a sterile, sorediate lichen having a trebouxioid photobiont, surprisingly prove that the species is conspecific with Lecanographa amylacea (Arthoniomycetes), a fertile, esorediate species with a trentepohlioid photobiont. These results suggest that L. amylacea and B. violaceofusca are photomorphs of the same mycobiont species, which, depending on the photobiont type, changes the morphology and the reproduction strategy. This is the first example of a lichenized fungus that can select between Trebouxia (Trebouxiophyceae) and trentepohlioid (Ulvophyceae) photobionts. Trebouxia photobionts from the sorediate morphotype belong to at least three different phylogenetic clades, and the results suggest that Lecanographa amylacea can capture the photobiont of other lichens such as Chrysothrix candelaris to form the sorediate morphotype. Phylogenetic analyses based on rbcL DNA data suggest that the trentepohlioid photobiont of L. amylacea is closely related to Trentepohlia isolated from fruticose lichens. The flexibility in the photobiont choice enables L. amylacea to use a larger range of tree hosts. This strategy helps the lichen to withstand changes of environmental conditions, to widen its distribution range and to increase its population size, which is particularly important for the survival of this rare species.

Two new genera in the subfamily Teloschistoideae (Teloschistaceae, Teloschistales) are described: Hosseusiella S. Y. Kondr., L. Lőkös et A. Thell for the Caloplaca chilensis group including three South American species and Rehmanniella S. Y. Kondr. et J.-S. Hur for the new species, R. wirthii S. Y. Kondr. from South Africa. The new genera are supported by a three-gene phylogeny based on ITS1/ITS2 nrDNA, 28S nrLSU, and 12S mtSSU sequenc- es. The new taxonomic position of Elixjohnia ovis-atra in the subfamily Teloschistoideae is discussed. The two new species Hosseusiella gallowayiana and Rehmanniella wirthii are described, illustrated and compared with closely related taxa. Hosseusiella gallowayiana is recorded for the first time as the host for the lichenicolous fungus Arthonia tetraspora S. Y. Kondr. A key to the species of Hosseusiella is included, as well as new information of the related genus Follmannia. The following new combinations are proposed: Hosseusiella chi- lensis (Kärnefelt, S. Y. Kondr., Frödén et Arup) S. Y. Kondr., L. Lőkös, Kärnefelt et A. Thell, Hosseusiella pergracilis (Zahlbr.) S. Y. Kondr., L. Lőkös, Kärnefelt et A.

The Volovec Mts (Volovské vrchy) have insufficiently been investigated area for lichens. Kojšovská hoľa is one of the highest parts in the Volovec Mts. No records of lichens were published from here. Some historical collections need revision. The list of 35 lichen species collected by the authors is presented from the investigated areas. Three interesting and vulnerable lichens are characterised in more details: Cladonia ciliata var. tenuis, Cladonia cornuta and Umbilicaria vellea. The area of Kojšovská hoľa gives further opportunities for new findings. biodiversity, Slovak Ore Mts, Volovec Mts

During lichenological explorations of tropical montane forests in Kenya, a remarkable new lichenicolous fungus was repeatedly found growing on thalli of the epiphytic tripartite cyanolichen Crocodia cf. clathrata. Molecular phylogenetic analyses placed the fungus within Gomphillaceae (Ostropales, Lecanoromycetes), a family mainly of lichen-symbiotic species in the tropics. The anatomical features (unitunicate, non-amyloid asci and simple, septate paraphyses) as well as the hemiangiocarpic ascoma development confirm its taxonomic affinity. DNA sequence data showed the closest relationship was with Gyalidea fritzei, followed by Corticifraga peltigerae. A monotypic genus, Taitaia, is introduced to incorporate a single species, T. aurea. The new fungus is characterized by aggregated ascomata with yellow margins and salmon red discs developing from a single base.
