Keywords: Altitude/ CBSC/ Gastropods/ Grazing damage/ Herbivory/ Lichen compounds/ Soil pH/ Stictic acid
Abstract: We quantified carbon based secondary compounds (CBSC) in 182 Lobaria pulmonaria thalli sampled in a range of forest types along an elevation gradient in southern Norway to assess the importance of external and internal factors as a source of variation for the CBSC content. The best multiple regression model for CBSC content included altitude, soil pH, dry weight (DW) per area and thallus size. Total CBSC content decreased with altitude and increased with pH. L. pulmonaria maximizes its CBSC content in sites with long gastropod grazing seasons (lowland forests) and high gastropod abundance (calcareous soils). Secondly, we assessed grazing damage in the L. pulmonaria thalli to test the hypothesis that natural populations of gastropods respond to the CBSC level in situ. We found a significantly negative correlation between the stictic acid concentration and grazing damage from gastropods, which is consistent with an evolutionary arms race between lichens and gastropods. This relationship became stronger when using the tree trunk as a factor in the ANCOVA, consistent with spatial variation in gastropod occurrences. © 2011 Elsevier Ltd and The British Mycological Society.

Abstract: The Caloplaca crenulatella species complex is monophyletic, based on analysis of ITS nrDNA sequences. It is characterized mainly by its ascospores and a simplified thallus. Caloplaca aquensis, C. borysthenica, C. interfulgens, C. lactea, C. marmorata and C. tominii represent well-defined monophyletic lineages within it. Caloplaca diffusa, described here as a new species, is a well-supported lineage with a distinctive phenotype. Caloplaca crenulatella s. lat. and C. ferrarii s. lat. are heterogeneous taxa appearing in four and two places respectively within our tree. Caloplaca ochracea also belongs to the group, although it has different ascospore characters. Caloplaca gyalolechiaeformis and C. pseudocitrina are later synonyms of C. tominii. Arctic and North American sorediate specimens morphologically very close to C. tominii represent a separate lineage recently recognized as C. erichansenii. The North American Caloplaca nashii has a C. crenulatella-like phenotype but does not belong to the C. crenulatella complex. The identities of Caloplaca lacteoides and Caloplaca epigaea are not clear, but the latter may be a terricolous ecotype of one of the entities within C. crenulatella s. lat. A key to the European species of the group is provided.

Abstract: The riparian forests along the river Inn in the Lower Engadine are the only sites where the endangered lichen Ramalina dilacerata can be found in Switzerland. The aim of this bachelor thesis was to asses size and state of the actual population of R. dilcerata and to compare the findings with observations done by Eduard Frey fifty years ago. R. dilacerata was observed on more than 200 trees, mainly on Alnus incana growing next to the open water of the course of the river. Contrary to Frey R. dilcerata was not found on coniferous trees. Around two-thirds of the actual population was found in protected areas of alluvial zones of national importance.

Abstract: The first full-length cDNA library for lichenized fungi was constructed from cultured mycobiont of the arid desert lichen Endocarpon pusillum. Based on small-scale sequencing results, 111 genes of the lichenized fungi were identified for the first time, among which 11 genes shared no homology with any known fungal genes. Real-time PCR showed that the size of the mycobiont genome is 39. 13 Mb and the copy number of ribosomal RNA gene repeat units is 43. The results of this study will be valuable for the ongoing lichen genome-sequencing project and the large-scale identification of functional genes from lichenized fungi. © 2011 Springer Science+Business Media B.V.

Keywords: Ecological restoration/ Florida scrub endemic and endangered plants/ Mechanical treatments/ Prescribed fire
Abstract: Exclusion of fire from pyrogenic ecosystems often results in changes in vegetation structure and the loss of biodiversity. Where landscape context constrains the application of fire, managers are applying mechanical treatments in conjunction with or as a surrogate for fire. We compared the effects of prescribed fire, mowing, mowing followed by fire, and a control at 2 fire-suppressed Florida scrub sites. Goals included increasing bare sand gaps, increasing endemic Florida scrub herbs, and reducing woody vegetation cover and height. We evaluated treatment effects on woody vegetation cover and height, ground cover (litter, lichens and bare ground), litter depth, and changes in the frequency and abundance of rare herbs prior to treatment and 1, 2 and 5 yr post-treatment. All treatments reduced woody vegetation cover and woody vegetation height relative to controls, and these effects often persisted for 5 yr post-treatment. In contrast, only treatments including fire resulted in consistent beneficial and long-lasting effects of increased bare sand cover, reduced litter and lichen cover, and reduced litter depth. Although the treatments had little effect on species composition and high variation made few comparisons statistically significant, burning (especially burning alone) increased occupancies and abundances of 2 rare species in some sites and in some years. In general, burning (with or without prior mowing) was more effective than mowing-alone or the control in restoring ground cover components and rare species populations. Fire provides unique benefits in the management of Florida scrub, and mechanical treatments are best used only when necessary to prepare sites for prescribed burning. ©2011 by the Board of Regents of the University of Wisconsin System.

Abstract: The worldwide population of the boreal felt lichen Erioderma pedicellatum is currently listed as Critically Endangered by the IUCN, with over 95% of the current population residing on the island of Newfoundland, Canada. Surveys of E. pedicellatum habitats and populations have primarily been opportunistic, rather than systematic, in nature. We used a geographic information system and compiled occurrence data and pseudo-absence data to develop the first predictive spatial distribution model for E. pedicellatum in Newfoundland. Of the suite of 19 models using 4 different parameters examined, the model with distance from coastline and topographic aspect was the best candidate. The final model had low sensitivity (i.e. a low ability to predict false presence), but high specificity (a strong ability to predict true absence). The final predictive model can contribute to future species status assessments and provincial conservation management decisions that require information on probable species distribution.

Abstract: The Forest Health Monitoring Program produces an annual technical report that has two main objectives. The first objective is to present information about forest health from a national perspective. The second objective is to present examples of useful techniques for analyzing forest health data new to the annual national reports and new applications of techniques formerly used. The report’s organizational framework is the Criteria and Indicators for the Conservation and Sustainable Management of Temperate and Boreal Forests of the Montreal Process. Here, we present an approach to examining landscape context of forest and grassland in the United States. We explore the influence of environmental factors such as climate and air quality on a lichen species diversity indicator across the continental United States. This includes an analysis of the potential for monitoring changes in these environmental factors. We use Forest Inventory and Analysis phase 3 data to describe aspects of forest communities such as understory species composition, richness, and distribution, including discussion of invasive and introduced species. Tree mortality, which has been examined in previous Forest Health Monitoring reports, is analyzed in this report using a more intensive dataset to demonstrate the utility of Forest Inventory and Analysis phase 2 data. We explore spatial modeling of ozone injury risk, along with microscale and landscape-scale ancillary data that can be used in the modeling analyses. A discussion of redbay ambrosia beetle/laurel wilt risk includes current beetle/ wilt distribution, host species distributions, climate matching, and spread modeling. Progress in monitoring and analyses of Phytophthora ramorum and sudden oak death is presented along with results from two different monitoring techniques.

Abstract: During the past decades, Ramalina calicaris was found in several areas in south-western Germany. In this region, the species was apparently continuously part of the lichen biota. The species had been correctly reported from south-western Germany until the 1950s, but was overlooked or misinterpreted afterwards. In 1999, R. calicaris was rediscovered under its correct name in the Suabian Alb.

Keywords: Asterinaceae/ Aulographaceae/ Dothideales/ Leaf fungi/ Micropeltidaceae/ Molecular phylogeny/ Trichothyriaceae
Abstract: The family Microthyriaceae sensu Lumbsch and Huhndorf 2010 is a poorly known but interesting family comprising 50 genera consisting of foliar epiphytes or saprobes on dead leaves and stems. We re-visited the family based on examinations of generic types where possible. Members are distributed in Aulographaceae, Asterinaceae, Microthyriaceae, Micropeltidaceae and Palmulariaceae and notes are provided on each of these families. Nine genera are transferred from Microthyriaceae to Asterinaceae, and two to Aulographaceae based on the splitting or dissolving nature of the thyriothecia to release ascospores. New sequence data for a number of species and genera are provided. Microthyriaceous members growing on other fungi and lichens differ from Microthyriaceae sensu stricto and the family Trichothyriaceae is reinstated to accommodate these taxa. Other genera of Microthyriaceae belong in Rhytismataceae, Stictidaceae, Venturiales incertae cedis, Dothideomyetes genera incertae cedis, Hypocreales incertae cedis and Ascomycota genera incertae cedis. The family Microthyriaceae is reduced to seven genera characterised by superficial, flattened thyriothecia, with the cells of the upper wall radiating in parallel arrangement from the distinct central ostiolar opening, while the lower peridium is generally poorly developed. Sequence data is provided for five species with thyriothecia and Paramicrothyrium and Neomicrothyrium are described as new genera and Micropeltis zingiberacicola is introduced as a new species. Our phylogenetic analysis underscores the high genetic diversity for thyriotheciate species and there is no clear clade that can be well defined as Microthyriales. Nuclear ribosomal data support multiple polyphyletic lineages within Microthyriaceae and Micropeltidaceae. Some unexpected DNA based phylogenetic relationships such as those between Muyocopron and Saccardoella will require corroboration with more complete taxon sampling as well as additional non ribosomal markers. There are few differences between Aulographaceae, Asterinaceae and Palmulariaceae and these families may need synonymising. © Kevin D. Hyde 2011.

Abstract: Although many studies have been conducted on the ecological functions and ecophysiological characteristics of lichen soil crusts (LSCs), no explanation of these results has been provided based on crust structures. Using algae soil crusts (ASCs) as comparison, this work studied the small-scale vertical distribution of algal biomass and stratification in two types of LSCs, by combining the binocular stereomicroscope observations, microscope observations, plate cultures, chlorophyll analysis, and polysaccharides analysis. The results showed an obvious difference in the proportion but not the composition of the algae species between the ASCs and the two LSCs. Approximately 60% and 80% of the total algal biomass were concentrated in the top 1 mm of the soil profile and thalli in the ASCs and LSCs, respectively. This implies that symbiotic algae are the dominant species and primary organic carbon producers in LSCs, and the algal biomass decreased with the depth in both the ASCs and LSCs. The small-scale vertical distributions of the crustal algal biomass and polysaccharides were characterized by obvious successional stage, whereas these were unrelated to the crust type within the successional stage. Additionally, a large amount of fungi, which were always piercing the entire crusts, were observed in the LSCs, but only occasionally in the ASCs. These special structures are purported to cause the LSCs to achieve specific ecological functions, such as higher carbon fixation and greater compressive strength. High biomass, large living space, and advantageous resource utilization privilege suggest that the lichen association is mutualistic and the direction from ASCs to LSCs is developmental. © 2011 Springer Science+Business Media, LLC.

Abstract: In China, Korea, and Japan, Umbilicaria esculenta is considered as both food and medicinal resources from lichen. In the current study, a prismatic crystal was first isolated from edible lichen U. esculenta via solvent fractionation. The structure of the crystalline compound was elucidated as allantoin using single-crystal X-ray crystallographic and spectroscopic techniques. In light of the wide use of synthesized allantoin in cosmetic industry as a skin protectant, the biological origin of the allantoin isolated from natural food stuff edible lichen has great potential to be developed into functional cosmetics. Current findings also provided useful information for ecologists to further explore the role of lichen and allantoin in nitrogen metabolism. © 2011 by the authors; licensee MDPI, Basel, Switzerland.

Keywords: Asymmetric synthesis/ Chemical ecology/ Chiral HPLC/ Female sex pheromone/ Lepidoptera/ Methyl-branched alcohol
Abstract: A methyl-branched heptadecanol was found in the pheromone gland extract of a female lichen moth, Miltochrista calamina (Arctiidae, Lithosiinae). GC-MS analyses of the alcohol and a hydrocarbon derived from it by subsequent treatments with methanesulfonyl chloride and LiAlD4 in microscale reactions indicated 5-methylheptadecan-7-ol (1) as one possible structure. The four stereoisomers of 1 in a ratio of 4:4:1:1 were prepared from (S)-b-citronellol with 60% ee, and were separated by a combination of achiral and chiral HPLC columns. The absolute configuration of each isomer was determined by the comparison with the chromatographic behaviors of other samples synthesized by a different scheme, which applied the Jacobsen hydrolytic kinetic resolution of racemic 1,2-epoxydodecane to fix the configuration of the 7-hydroxy group. Only the (5R,7R)-isomer attracted male moths; thus, we concluded that M. calamina females secrete (5R,7R)-1 as a sex pheromone, indicating a new chemical class of lepidopteran female sex pheromones. © 2011 Elsevier Ltd.

Abstract: An actinomycete strain, IR73-Li102T, was isolated from a lichen sample obtained from Iriomote Island, Japan, and subsequently characterized using a polyphasic approach. Comparative 16S rRNA gene sequence analysis revealed that strain IR73-Li102Thad the highest sequence similarities with Actinomycetospora chiangmaiensis YIM 0006T(98.3%), A. corticola 014-5T(98.1%) and A. rishiriensis RI109-Li102 T (98.0%). However, DNA-DNA hybridization assays, as well as physiological and biochemical analyzes, showed that strain IR73-Li102T could be clearly differentiated from its closest phylogenetic relatives. The strain contained meso-diaminopimelic acid, and arabinose and galactose were present in whole-cell hydrolysates. The predominant menaquinone was MK-8(H 4), and the diagnostic phospholipids were phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol and diphosphatidylglycerol. The major cellular fatty acid was iso-C 16:0 (58%). The chemotaxonomic properties of strain IR73-Li102 T were consistent with those shared by members of the genus Actinomycetospora. On the basis of the phenotypic features and DNA-DNA hybridization data, strain IR73-Li102 T ( NBRC 106365T KCTC 19783T) represents a novel species of the genus Actinomycetospora, for which the name Actinomycetospora iriomotensis sp. nov. is proposed.

Abstract: An actinomycete, strain RI109-Li102T, was isolated from a lichen sample obtained from Rishiri Island in Japan. Cells of strain RI109-Li102T were Gram-positive, aerobic and non-motile and formed bud-like spore chains. The isolate grew with 0-3% (w/v) NaCl, at pH 5-9 and at 10-30 °C (optimum 30 °C). The whole-cell hydrolysate contained meso-diaminopimelic acid, arabinose and galactose. The predominant menaquinone was MK-8(H4) and the diagnostic phospholipids were phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol and diphosphatidylglycerol. The major cellular fatty acids were iso-C16: 0 and iso-C16: 1 H. Comparative 16S rRNA gene sequence analysis revealed that strain RI109-Li102T was most closely related to Actinomycetospora corticicola 014-5T (99.0% rRNA gene sequence similarity) and Actinomycetospora chiangmaiensis YIM 0006T (98.4%). However, DNA-DNA hybridization assays, as well as physiological and biochemical analyses, showed that strain RI109-Li102T could be differentiated from its closest phylogenetic relatives. It is proposed that strain RI109-Li102T (=NBRC 106356T =KCTC 19782T) be classified as the type strain of a novel species, with the name Actinomycetospora rishiriensis sp. nov. © 2011 IUMS.

Abstract: [The four new species can all disguise the shell with a cover of lichens, soil, or both, to reduce predation. When the covering is made of hygroscopic lichen, it might function as a water or humidity reservoir as well as for camouflage.] Four new species of Napaeus are described from La Gomera (Canary Islands), which is one of the smaller islands of the archipelago but has the highest number of Napaeus species. The four new species can all disguise the shell with a cover of lichens, soil, or both, to reduce predation. When the covering is made of hygroscopic lichen, it might function as a water or humidity reservoir as well as for camouflage.

Abstract: Air pollution and associated heavy metal pollution, is an important environmental problem. One of the methods used to monitor heavy pollution in the air is the method of transplanting lichen samples by the bag technique. In this study, Pseudevernia furfuracea was used as a bioindicator to determine the heavy metal level of air pollution heavy metal level in Kayseri and to generate an air pollution map of the city. The lichen samples were collected from the Yaprakli̇ Mountains in Çanki̇ri̇ in 2002 and transplanted to 10 different stations in Kayseri. Lichen samples were re-collected at two different periods in three month intervals. Inductively coupled plasma (ICP) spectrometry was used to identify the heavy metals, such as Cu, Cd, Mn, Ni, Pb and Zn in the lichen samples. The chlorophyll a and b contents were determined by using the DMSO method. With these values chlorophyll a+b, a/b and b/a were also calculated. According to the heavy metal analysis results of Pseudevernia furfuracea, which worked well as a bioindicator, air pollution in Kayseri due to industry, heating and traffic was observed. The concentration of Cd at the 3rd and 9th station, Cu concentration at the 1st and 8th station, Mn concentration at the 3rd and 10th and Pb concentration at the 3rd, 8th and 10th station were considerably high. In addition to these, the concentration of Zn was observed high at 9th station.

Abstract: Antarctic plant communities are dominated by lichens and mosses which accumulate semivolatile organic compounds (SOCs) such as polybrominated diphenyl ethers (PBDEs) directly from the atmosphere. Differences in the levels of PBDEs observed in lichens and mosses collected at King George Island in the austral summers 2004-05 and 2005-06 are probably explained by environmental and/or plant parameters. Contamination of lichens showed a positive correlation with local precipitation, suggesting that wet deposition processes are a major mechanism controlling the uptake of most PBDE congeners. These findings are in agreement with physical-chemical data supporting that tetra- through hepta-BDEs in the Antarctic atmosphere are basically bound to aerosols. Conversely, accumulation of PBDEs in mosses appears to be controlled by other environmental factors and/or plant-specific characteristics. Model simulations demonstrated that an ocean-atmosphere coupling may have played a role in the long-range transport of less volatile SOCs such as PBDEs to Antarctica. According to simulations, the atmosphere is the most important transport medium for PBDEs while the surface ocean serves as a temporary storage compartment, boosting the deposition/volatilization "hopping" effect similarly to vegetation on continents. © 2011 Elsevier B.V.

Abstract: This work deals with the survival analyses of the symbionts isolated from the lichen E. pusillum under desiccation and starvation stress. The mycobiont of the symbionts was under the desiccation in combination with starvation stress, and under starvation stress alone as well. The phycobiont of the symbionts was under desiccation stress alone. The experiments were detected by means of the biomass size, weight and cell density, deformity of the hyphae and cells, and metabolic activity through SEM (scanning electron microscopy), TEM (transmission electron microscopy), FM (fluorescence microscopy), spectrophotometry, and FCM (flow cytometry). The results show that the mycobiont can survive for seven months under desiccation stress in combination with starvation stress, and for eight months under starvation stress alone. The phycobiont can survive for two months under desiccation stress. It can provide a scientific basis for further research of the reproduction biology of lichens and arid desert biocarpet engineering to fix sand and carbon.

Abstract: The Norilsk industrial ore smelting complex (Taymyr Peninsula, Russian Federation) has significantly impacted many components of local terrestrial and aquatic environments.Whether it has had a major impact on the wider Russian Arctic remains controversial as studies are scarce. From 1986 to 2004, data on heavy metal (Cu, Ni, Zn, Hg, Cd and Hg) concentrations in fish (burbot), moss, lichens, periphyton, hydric soils and snow in and around Norilsk and the most northern parts of the Taymyr Peninsula were analysed. Very high concentrations of Cu (203 µg L-1± 51 µg L-1) and Ni (113 µg L-1± 15 µg L-1) were found in the water of the Schuchya River close to Norilsk. Heavy metal concentrations in burbot liver were highest in Lake Pyasino near Norilsk compared to other study regions that were >100 km distant. From 1989-1996, Cu (121 µg L-1± 39 µg L-1 SD), Zn (150 µg L-1± 70 µg L -1) and Ni (149 µg L-1± 72 µg L-1) snow concentrations were greatest in Norilsk, but were low elsewhere. By 2004, these concentrations had dropped significantly, especially for Cu-74 µg L-1 (±18.7 µg L-1 SD), Zn- 81.7 µg L -1 (±31.3 µg L-1 SD) and Ni-80 µg L -1 (±18.0 µg L-1 SD). Norilsk and its surroundings are subject to heavy pollution from the Norilsk metallurgical industry but these are absent from the greater Arctic region due to the prevailing winds and the Byrranga Mountains. Pollution abatement measures have been made so further investigations are necessary in order to assess their efficiency. © Springer Science+Business Media B.V. 2010.

Abstract: Lichen samples were collected from Gunung Machincang, Langkawi Islands based on an alternation of altitudes, which are 0, 300 and above 600 m. Morphological identification resulted in 15 genera of microlichens (crustose) and five genera of macrolichens (foliose) and they fall under 14 families. As the altitude increases, the number of foliose type of lichen also increased. The common microlichens obtained were from the Family of Graphidaceae and can be found from the sea level right up to the peak of Gunung Machincang. The most common crustose lichens found were Heterodermia sp., while Eugenia sp. is the most common tree habitat for lichens in Gunung Machincang, Langkawi Islands. This study represents the first record of lichens in Gunung Machincang, Langkawi Islands, Malaysia.

Abstract: Landspraying while drilling (LWD) is an approved disposal method for water-based drilling mud (WBM) systems in western Canada. The mud is applied either on cultivated land, where it is incorporated by cultivation, or on vegetated land where it is not incorporated. This study examined the effects of summer WBM application (0, 15, 20, 40, and 80 m3·ha -1) on native vegetation properties. Our results indicated that LWD increased bare ground but decreased lichen cover at the 80 m3· ha-1 rate relative to the untreated control. Nitrogen (N), sulfur (S), and magnesium (Mg) concentrations in aboveground plant tissue increased with increasing LWD rate in samples taken 45 d after WBM application, but these differences disappeared 1 yr after treatment. Increase in tissue concentration of phosphorus (P) with LWD rate, however, was only detected 3 yr after LWD. Nonetheless, these changes in tissue chemistry were not associated with significant changes in biomass yield or species composition. Overall, our results suggest that single WBM applications at rates (=20 m 3·ha-1) commonly used in western Canada, if properly managed, are unlikely to adversely affect native prairie vegetation. © 2011 Society for Range Management.

Abstract: To evaluate the current delimitation of broadly distributed morphospecies from the Lecanora dispersa group, the nuclear ribosomal internal transcribed spacer region (ITS1, 5.8S and ITS2) was analyzed phylogenetically and compared to phenotypic data variation within and among species. Phylogenetic relationships among 34 individuals representing eight species from the L. dispersa group, collected mainly from Poland and other European countries, were inferred using two types of Bayesian analyses (with and without a priori alignments), maximum likelihood and maximum parsimony approaches. The highest phylogenetic resolution and the largest number of significantly supported internodes resulted from the Bayesian analysis without a priori alignment. Inferred phylogenies confirmed a broader delimitation of the L. dispersa group, to include four additional lobate taxa: L. contractula, L. pruinosa, L. reuteri, and L. thuleana (Arctopeltis thuleana). Lecanora crenulata, L. dispersa, L. reuterii, and the core of L. albescens and L. semipallida were all found to be monophyletic with high support (by at least one phylogenetic analysis) except the first species. Based on the ITS region, phenotypically similar individuals, thought to belong to one monophyletic group, were found to belong to multiple distantly related groups (e.g., members of L. albescens and L. hagenii), suggesting that morphological, anatomical and chemical characters may not be consistent in predicting species boundaries within the L. dispersa group. Potential undescribed species were found within phenotypically defined L. albescens and L. semipallida. Phylo-taxonomic studies of the L. dispersa group with more loci and a more extensive taxon sampling are urgently needed. © 2012 The American Bryological and Lichenological Society, Inc.

Abstract: The distribution of a series of elements in lacustrine environments from Terra Nova Bay, Northern Victoria Land, Antarctica, has been examined, in order to gain insight into the natural processes regulating species distribution, and to detect possible present or future local and/or global anthropogenic contamination. Attention was focused on freshwaters, algae, mosses, and lichens (one site only). Lake water composition was found to be influenced by marine spray, lake geographical position and meltwater input. Bioaccumulation of elements by algae was observed. Higher element concentrations in algae than in mosses have been interpreted taking into account this phenomenon. Data processing by chemometric techniques showed correlations between elements and similarities among samples. No evidence of a detectable metal contamination was found in the investigated area. © 2012 Elsevier B.V.

Abstract: Local variation (within sampling sites) affects lichen air pollution biomonitoring of trace element deposition patterns. When comparing between sampling sites, global variation must be greater than local variation, thus reducing local variation is important in biomonitoring studies. To reduce local variability, sampling protocols are introduced, primarily minimum sampling height and less often sampling aspect. This study, introduces further protocols, which can help to reduce within site variation. First, the research design removed spatial variation by sampling a single tree. One-thousand and thirty-seven individual specimens of Usnea subfloridana were collected and aggregated into 97 samples based on similar collection height, aspect and mass. Samples were tested by inductively coupled plasma

Abstract: Lichen community composition was evaluated for both lichen cover and richness on a cliff face commonly used for recreational rock climbing. The sandstone outcrop is located on the Sibley Peninsula, which extends from the north shore of Lake Superior. One-hundred and twenty plots were examined. Each plot was 1 m2 in size, with 60 plots located on unclimbed cliff sections and 60 more located where recreational rock climbing regularly occurs. Lichen richness and cover were significantly lower on the rock climbing sections compared with unclimbed sections. Linear regression models indicated significant relationships with cover and richness to environmental response variables and climbing treatment. Detren ded correspondence analysis indicated a separation of lichen community groups on this cliff, and major separations occurred between plots in each climbing treatment. Canonical correspondence analysis indicated a significant amount of community group variation between climbed and unclimbed locations related to climbing treatment and aspect of the plots. Climbing is found to have an imp act on this sandstone cliff-face lichen community.

Abstract: Platismatia wheeleri was recently described as a species distinct from the highly morphologically variable Platismatia glauca. Previously, P. wheeleri was known only from intermountain western North America in southern British Columbia, Idaho, Montana, Oregon and Washington. After examining collections from the New York Botanical Garden and Arizona State University herbaria we discovered that P. wheeleri was collected in southern California and the Tatra Mountains of Slovakia. The morphology, ecology and biogeography of P. wheeleri are discussed, and the importance and utility of historical collections is highlighted. This article is intended to alert researchers to the potential presence of P. wheeleri in different regions of the world so we can better understand its historical and current distribution and abundance.

Abstract: The objective of this paper was to assess the air pollution and the main sources of Air Particulate Matter in the Setúbal urban/industrial area, Portugal. PM2.5 and PM2.5-10 were sampled in Nuclepore filters and lichens transplants were exposed during 9 months. The levels of elements in these two matrixes were measured by INAA and PIXE. A large data base was created and source apportionment was performed by using Principal Component Analysis. The results showed that the main sources of fine particles were anthropogenic and were related with traffic and local industry. There was an important contribution of natural sources, mainly for the coarse fraction, associated with the sea and the soil. Lichens characterization and mapping showed that different site-specific characteristics controlled the spatial distribution of different elements. This study showed that biomonitoring is an effective complementary method to traditional sampling systems. © 2011 Akadémiai Kiadó, Budapest, Hungary.

Abstract: Throughout the world, epidemiological studies were established to examine the relationship between air pollution and mortality rates and adverse respiratory health effects. However, despite the years of discussion the correlation between adverse health effects and atmospheric pollution remains controversial, partly because these studies are frequently restricted to small and well-monitored areas. Monitoring air pollution is complex due to the large spatial and temp variations of pollution phenomena, the high costs of recording instruments, and the low sampling density of a purely instrumental approach. Therefore, together with the traditional instrumental monitoring, bioindication techniques allow for the mapping of pollution effects over wide areas with a high sampling density. In this study, instrumental and biomonitoring techniques were integrated to support an epidemiological study that will be developed in an industrial area located in Gijon in the coastal of central Asturias, Spain. Three main objectives were proposed to (i) analyze temporal patterns of PM10 concentrations in order to apportion emissions sources, (ii) investigate spatial patterns of lichen conductivity to identify the impact of the studied industrial area in air quality, and (iii) establish relationships amongst lichen conductivity with some site-specific characteristics. Samples of the epiphytic lichen Parmelia sulcata were transplanted in a grid of 18 by 20 km with an industrial area in the center. Lichens were exposed for a 5-mo period starting in April 2010. After exposure, lichen samples were soaked in 18-M? water aimed at determination of water electrical conductivity and, consequently, lichen vitality and cell damage. A marked decreasing gradient of lichens conductivity relative to distance from the emitting sources was observed. Transplants from a sampling site proximal to the industrial area reached values 10-fold higher than levels far from it. This finding showed that lichens reacted physiologically in the polluted industrial area as evidenced by increased conductivity correlated to contamination level. The integration of temporal PM10 measurements and analysis of wind direction corroborated the importance of this industrialized region for air quality measurements and identified the relevance of traffic for the urban area. © 2012 Copyright Taylor and Francis Group, LLC.

Abstract: Molecular phylogenies inferred from the nuclear small subunit rRNA gene (nuSSU), nuclear large subunit rRNA gene D1/D2 region (nuLSU), and ITS-5.8S rRNA gene (ITS) indicated that five cultures of the lichenized hyphomycete Dictyocatenulata alba isolated from Japan form a monophyletic clade with high bootstrap support, and a close relationship to the Ostropomycetidae (Lecanoromycetes, Pezizomycotina, Ascomycota). Insertion sequences were found in the nuSSU of all isolates [e.g., nine insertions in the strain JCM 5358 (Japan Collection of Microorganisms)], some of which were group I introns. Five new insertion positions were found among the D. alba isolates. Using BLAST, none of the insertion sequences of D. alba were closely related to those of fungi or other organisms deposited in public DNA databases. Insertion positions were similar in some isolates, and two positions were common to all isolates. Although all phylogenetic analyses based on nuSSU, nuLSU, and ITS revealed the monophyly of D. alba, the isolates were divided into two (in the nuSSU tree) or three (in the nuLSU and ITS trees) groups. Based on the phylogenetic analyses and the intron-exon structures, the five isolates identified as D. alba belong to three cryptic species and therefore D. alba should be considered a species complex. The very slow-growing, tough agar colonies of the isolates, the occurrence of the species on both slightly lichenized and nonlichenized surfaces of trees, or pebbles (rarely on soil), suggest that the members of the D. alba complex may be lichenized. The photobiont was not clearly identified in this study. © 2012 The British Mycological Society.

Keywords: Copper-sulphide mine/ Lichens/ Native plants/ Rare earth elements/ Tailings
Abstract: Native plant species, lichens and tailings, sampled from a copper-sulphide mining area located in southern-eastern Portugal, were analysed by neutron activation analysis (INAA) for determination of rare earth elements (REEs). Values of ?REEs and individual REEs concentration of tailing samples are higher than those of natural background concentrations. The higher values of REEs are found in modern slags and the mixture of oxidized gossan and sulphide disseminated country rocks when compared with the alluvial sediments contaminated by mine tailings. The total concentrations of light REEs are higher than those of heavy REEs in all tailing samples. Distribution patterns of PAAS-normalized REEs in mine tailings show slightly LREE enriched and flat HREE pattern with negative Eu anomaly. Lichens accumulated higher concentration of lanthanides than vascular plants. The elevated levels of REEs in lichen, native plant species and tailing samples reflect the contamination of REEs in São Domingos mining area. The Carlina corymbosa, Erica australis and Lavandula luisierra accumulated the higher amounts of La, Ce and other REEs than the other plant species grown in this mining area. © 2012 Akadémiai Kiadó, Budapest, Hungary.

Abstract: Leptogium hibernicum was first recorded in North America in 2009 from near Hectanooga in southwestern Nova Scotia, Canada, and the identification was confirmed by P.M.Jørgensen. A 2011 collection from Great Smoky Mountain National Park appeared to be a second occurrence. Subsequently, specimens identified as Leptogium laceroides from the southern Appalachian Mountains were reviewed and compared to the Nova Scotia material of L. hibernicum. The comparison of external morphology and thallus sections in water revealed two earlier collections of L. hibernicum from the southern Appalachians, thereby extending its known range on the continent.
