[RLL List # 235 / Rec.# 35443] Abstract: Hypogymnia pulverata appears to be uncommon in North America. Previous collections are known from Alaska, Oregon, and near the coast of Hudson Bay in northwestern Québec. Here we report it from Mont Olivine and along the Rivière Sainte-Anne in Parc national de la Gaspésie, Québec. These occurrences are approximately 1,000 km southeast of the Hudson Bay locality, and extend the known range of H. pulverata to the Atlantic Coastal Region of eastern North America.-->

Previously sampled genetic data from Newfoundland were reanalyzed and new sequence data (16S rDNA, rbcLX) of the boreal felt lichen from Alaska (USA), Kamchatka (Russia), and North Trøndelag (Norway) were generated. The highest genetic diversity of the photobiont is found in Alaska and Kamchatka, indicating that these may be the primary sources of the species in the Northern Hemisphere. In Newfoundland, the photobiont of E. pedicellatum was screened on leaves of the symbiotic liverwort Frullania asagrayana and it was found to occur on trees where no other lichens were present, demonstrating that the geographical distribution, and possibly also the ecological requirement of the photobiont of E. pedicellatum, is wider than that of the lichen phenotype. Finally, a postulated association between the occurrence of the vegetatively reproducing Coccocarpia palmicola and the occurrence of the compatible photobiont of E. pedicellatum on the same tree could not be established. – doi:10.1017/S0024282916000311 URL: http://dx.doi.org.nybg.idm.oclc.org/10.1017/S0024282916000311 [Edit/Delete] [Upload PDF/URL]

It is probably related to some of the species currently assigned to the genus Puttea, but is included in Lecidea awaiting a more thorough revision of this group. The species is characterized by pale to dark brown apothecia, plusiosporic asci and by the production of secalonic acid A in the hypothecium causing a golden yellow reaction with KOH. Lecidea coriacea seems to be a species of oldgrowth forests and is threatened by forestry. It often grows on old trees of Betula, Picea and Salix or on old conifer snags.

[RLL List # 246 / Rec.# 38738] Keywords: PALEOECOLOGY/ EVOLUTION/ SAIGA ANTELOPE (SAIGA TATARICA)/ CARBON-13/ NITROGEN-15/ MAMMOTH STEPPE/ CONSERVATION PALEOBIOLOGY Abstract: Saiga antelope (Saiga tatarica) is one of the typical late Pleistocene species of the cold and arid mammoth steppe that covered a large area of northern hemisphere. The species is currently endangered and persists only in small areas of Central Asian steppe and desert ecosystems. The investigation of the ecology of the Pleistocene saiga using stable isotope ratios (ÎŽ13C, ÎŽ15N) aimed to decipher how different their diet and habitat were from those observed nowadays in relict populations. Up to 76 samples of bone collagen of ancient saiga from Western Europe, Siberia and Eastern Beringia were analysed and compared with 52 samples of hair and bone collagen of modern specimens from Kazahkstan, Russia and Mongolia. The ÎŽ13C values of the ancient saiga do not exhibit a clear trend over time. They cover the same range of values as the modern ones, from a C3-dominated to a C3-C4-dominated mixed diet (including probably Chenopodiaceae). In contrast, the ÎŽ15N values of fossil saigas are more variable and lower on average than the extant ones. The lowest ÎŽ15N values of ancient saiga are found around the Last Glacial Maximum, reflecting the influence of the cold conditions at that time. On the other hand, fossil saiga occupying the same regions as the historical and modern populations exhibit high ÎŽ15N values similar to the modern ones, confirming ecological continuity over time. Modern saiga is thus occupying just one of its potential diverse habitats they used in the past. Therefore, the extant saiga is not a refugee species confined to a suboptimal habitat. During the late Pleistocene, the saiga occupied a separate niche compared with the other ungulates of the mammoth steppe. However, this species could also adapt to a lichen-dominated diet normally seen in reindeer, leading to an isotopic overlap between the two species in south-western France and Alaska around the Last Glacial Maximum. This adaptation allowed a geographical expansion that does not correspond to a habitat-tracking episode. Hence, the realized niche currently observed for the saiga is reduced compared with their potential capacity for adaptation, a crucially important factor for the conservation of this endangered species. – doi:10.1016/j.quascirev.2017.01.022 URL: http://www.sciencedirect.com/science/article/pii/S027737911730094X [Edit/Delete] [Upload PDF/URL]

[RLL List # 246 / Rec.# 38699] Abstract: Bristle-thighed Curlews (Numenius tahitiensis, hereafter ‘curlews') breed only on low Arctic tundra in the southern Nulato Hills of the Yukon Delta National Wildlife Refuge (NWR) and on the Seward Peninsula, Alaska. Curlews use several distinct habitat types on the breeding grounds; however, quantified data of habitat use by curlews exist only for the Seward Peninsula. We investigated which available habitats on the breeding grounds were used most often by curlews in the Nulato Hills and compared availability with use to determine habitat selection using a land cover layer created in ArcGIS based on aerial photography and ground referenced locations. We also compared curlew habitat usage at our study site to habitats used on the Seward Peninsula. We used vegetation quadrats to determine plant composition within each habitat. We also determined percentage of habitat and plant composition within curlew territories. Curlews preferred shrub meadow tundra which consisted primarily of lichens (>50%), mixed with graminoid/herbaceous plants (~13%) and few dwarf shrubs. Medium/tall shrub habitats, especially tall shrub thickets, were generally avoided by curlews on the ground, but the curlews were commonly observed flying and displaying over the shrubs. Low shrub tussock tundra and sedge wet meadows were occasionally used by curlews but not to the extent of shrub meadow tundra. The avoidance by curlews of areas with medium to tall shrubs was probably related to potential predation risks associated with reduced visibility in these habitats. Habitat selection was similar for both breeding populations of curlews, except curlews at our study site used shrub meadow tundra more frequently and low shrub tussock tundra and sedge wet meadow to a lesser degree than on the Seward Peninsula. Habitats differed in number of berry-producing plants. Berry-producing plants were predicted to be highest in the habitat curlews selected most (i.e., shrub meadow tundra); however, they were most abundant in habitats associated with tussocks. – doi:10.1676/15-165.1 Countries/Continents: U.S.A/North America URL: http://www.bioone.org/doi/abs/10.1676/15-165.1 [Edit/Delete] [Upload PDF/URL]

[RLL List # 243 / Rec.# 37734] Abstract: Soil is a significant source of CO2 emission to the atmosphere, and this process is accelerating at high latitudes due to rapidly changing climates. To investigate the sensitivity of soil CO2 emissions to high temporal frequency variations in climate, we performed continuous monitoring of soil CO2 efflux using Forced Diffusion (FD) chambers at half-hour intervals, across three representative Alaskan soil cover types with underlying permafrost. These sites were established during the growing season of 2015, on the Seward Peninsula of western Alaska. Our chamber system is conceptually similar to a dynamic chamber, though FD is more durable and water-resistant and consumes less power, lending itself to remote deployments. We first conducted methodological tests, testing different frequencies of measurement, and did not observe a significant difference between collecting data at 30-min and 10-min measurement intervals (averaged half-hourly) (p < 0.001).Temperature and thaw depth, meanwhile, are important parameters in influencing soil carbon emission. At the study sites, we observed cumulative soil CO2 emissions of 62.0, 126.3, and 133.5 gC m-2 for the growing period, in sphagnum, lichen, and tussock, respectively, corresponding to 83.8, 63.7, and 79.6% of annual carbon emissions. Growing season soil carbon emissions extrapolated over the region equated to 0.17 ± 0.06 MgC over the measurement period. This was 47% higher than previous estimates from coarse-resolution manual chamber sampling, presumably because it better captured high efflux events. This finding demonstrates how differences in measurement method and frequency can impact interpretations of seasonal and annual soil carbon budgets. We conclude that annual CO2 efflux-measurements using FD chamber networks would be an effective means for quantifying growing and non-growing season soil carbon budgets, with optimal pairing with time-lapse imagery for tracking local and regional changes in environment and climate in a warming Arctic. – doi:10.1016/ j.scitotenv.2016.05.052 URL: http://www.sciencedirect.com/science/article/pii/S0048969716309834 [Edit/Delete] [Upload PDF/URL]

To date three terminal moraines of an Alaskan glacier, we used a new lichenometric technique in which surfaces are dated by comparing lichen population distributions with the predictions of ecological demography models with explicit rules for the biological processes that govern lichen populations: colonization, growth, and survival. These rules were inferred from size-frequency distributions of lichens on calibration surfaces, but could be taken directly from biological studies. Working with two lichen taxa, we used multinomial-based likelihood functions to compare model predictions with measured lichen populations, using only the thalli in the largest 25% of the size distribution. Joint likelihoods that combine the results of both species estimated moraine ages of ad 1938, 1917, and 1816. Ages predicted by Rhizocarpon alone were older than those of P. pubescens. Predicted ages are geologically plausible, and reveal glacier terminus retreat after a Little Ice Age maximum advance around ad 1816, with accelerated retreat starting in the early to mid twentieth century. Importantly, our technique permits calculation of prediction and model uncertainty. We attribute large confidence intervals for some dates to the use of the biologically variable Rhizocarpon subgenus, small sample sizes, and high inferred lichen mortality. We also suggest the need for improvement in demographic models. A primary advantage of our technique is that a process-based approach to lichenometry will allow direct incorporation of ongoing advances in lichen biology. © 2013 Swedish Society for Anthropology and Geography.

[RLL List # 245 / Rec.# 38202] Abstract: Two new species of Bryoria are described based on morphology, chemistry and molecular phylogeny (ITS and Mcm7). Both species belong in section Bryoria, which was resolved as a polyphyletic group in the ITS+Mcm7 phylogeny. Bryoria Alaskana belongs to a clade restricted to South-East Asia and north-west North America, and is so far known from south-east Alaska and the Sino-Himalayan Mountains. This highly variable species is most reliably recognized by its pendent, esorediate thallus, its production of fumarprotocetraric acid, and the combination of isotomic branching, abundant, whitish, predominantly fusiform pseudocyphellae, and sparse, short perpendicular side branches.

[RLL List # 241 / Rec.# 36618] Keywords: ALASKA/ COMMUNITY ASSEMBLY/ DENALI/ DISTURBANCE/ FIRE/ FUNCTIONAL TRAITS/ GROWTH FORM/ LICHEN/ PHOTOBIONT/ VEGETATIVE DISPERSAL Abstract: Abstract Questions Popular methods to analyse community–trait–environment relationships constrain community patterns by trait and environment relationships. What if some traits are strongly associated with community composition but unrelated to environmental variables and vice versa? We take a different approach, unconstrained by this assumption using non-parametric methods. We applied this technique to lichen (fungal/algal and/or cyanobacterial symbioses) communities across environmental and fire age gradients by measuring richness and cover of four important functional traits: energy generation (type of photosynthetic symbiont), water relations (inferred from growth form), dispersal capability (from vegetative propagules) and microsite specificity (measured by substrate affinity). Location Denali National Park and Preserve, Alaska, USA. Methods We ordinated plots in species space and regressed trait and environmental variables against ordination axes, resulting in one- or two-dimensional trait and environment surfaces. We then superimposed these surfaces on the ordination to create a new visual display, the ‘hilltop plot’, which enabled simultaneous measurement and display of one- and two-dimensional, non-linear community–trait–environment associations. Results Most traits examined show non-linear relationships with community structure. Fire favoured simple cladoniiform lichens, species with higher vegetative dispersal capacity and specificity to grow on wood, but excluded the ‘reindeer’ lichens, which had lower cover even more than 20 yrs after fire. Forests had more sorediate lichens than non-forested habitats, whereas high elevation, rocky areas had more green algal and fruticose lichens. Cyanobacterial lichen richness was positively related to shrub cover, while tripartite (cyanobacteria and green algae in a single lichen) and foliose lichen richness was highest in areas with higher moss cover. Conclusions Different combinations of lichen functional traits peaked along environmental and disturbance gradients, which we interpreted as balancing energy generation, water relations, vegetative dispersal and habitat specificity. Our method of trait–environment–community analysis revealed numerous one- and two-dimensional, non-linear relationships between community composition and functional traits, environmental variables and fire age gradients, which informed mechanisms behind community assembly. Our results indicate non-parametric and non-linear methods of trait–environment–community analysis have the potential to detect patterns that would have been missed using current popular techniques. – doi:10.1111/jvs.12286 URL: http://onlinelibrary.wiley.com/doi/10.1111/jvs.12286/abstract [Edit/Delete] [Upload PDF/URL]

[RLL List # 240 / Rec.# 36415] Keywords: ALASKA/ GATES OF THE ARCTIC NATIONAL PARK AND PRESERVE/ GROWTH-FORM/ PHOTOBIONT/ VEGETATIVE DISPERSAL Abstract: Lichens in the Arctic play important ecological roles. They also face the threats of increasing fire and shrub and tree expansion, exacerbated or caused by climate change. These forces may lead to changes not only in lichen community composition but also in the abundance, diversity and distribution of lichen functional traits. We sought to connect landscape-scale patterns of lichen community composition and traits to environmental gradients to both monitor lichen communities and clarify community-trait-environment relationships. We measured lichens throughout one of the largest and most remote U.S. National Parks within the Arctic. We then analyzed lichen community composition and species richness within ecologically informative lichen trait groups along environmental and vascular vegetation gradients. Macrolichen species richness in 0.4 ha plots averaged 41 species with a total landscape level observed gamma diversity of 262 macrolichen species. Jackknife estimators placed the landscape level macrolichen diversity at 307 to 331 species. A gradient from low-elevation forests to high elevation rocky areas was the dominant ecological gradient as expressed by the lichen community, representing 68% of the variation in species composition. Low-elevation forests hosted more epiphytic lichens characteristic of boreal forests, whereas high-elevation lichen communities were characterized by saxicolous lichens, varying between siliceous, basic or mafic rock types. Along this gradient, species reproducing vegetatively and lichens with filamentous growth form were more frequent in forests while the diversity of traits was highest in alpine habitats. Simple cladoniiform, as opposed to erectly branched fruticose lichens in the genus Cladonia, were the only functional group associated with tussock tundra. Vegetation types differed significantly in lichen species composition and richness and trait richness; characteristic suites of lichen species and traits are associated with the particular vegetation types in the Arctic. We also extended the range of Fuscopannaria abscondita reported new to North America and Zahlbrucknerella calcarea new to Alaska. – doi:10.1639/0007-2745-118.3.252 Countries/Continents: North America/U.S.A.

[RLL List # 243 / Rec.# 37634] Keywords: ALASKA/ ALEUTIAN/ ALTERNATIVE STATE/ CARIBOU/ IRRUPTION/ ISOTOPE/ MINERALIZATION/ NITROGEN/ PLANT/ RANGIFER TARANDUS/ REINDEER/ SOIL Abstract: Introductions of mammalian herbivores to remote islands without predators provide a natural experiment to ask how temporal and spatial variation in herbivory intensity alter feedbacks between plant and soil processes. We investigated ecosystem effects resulting from introductions of Rangifer tarandus (hereafter "Rangifer") to native mammalian predator- and herbivore-free islands in the Aleutian archipelago of Alaska. We hypothesized that the maritime tundra of these islands would experience either: (1) accelerated ecosystem processes mediated by positive feedbacks between increased graminoid production and rapid nitrogen cycling; or (2) decelerated processes mediated by herbivory that stimulated shrub domination and lowered soil fertility We measured summer plant and soil properties across three islands representing a chronosequence of elapsed time post-Rangifer introduction (Atka: ~100 yr; Adak: ~50; KagAlaska: ~0), with distinct stages of irruptive population dynamics of Rangifer nested within each island (Atka: irruption, K-overshoot, decline, K-re-equilibration; Adak: irruption, K-overshoot; KagAlaska: initial introduction). We also measured Rangifer spatial use within islands (indexed by pellet group counts) to determine how ecosystem processes responded to spatial variation in herbivory. Vegetation community response to herbivory varied with temporal and spatial scale. When comparing temporal effects using the island chronosequence, increased time since herbivore introduction led to more graminoids and fewer dwarf-shrubs, lichens, and mosses. Slow-growing Cladonia lichens that are highly preferred winter forage were decimated on both long-term Rangifer-occupied islands. In addition, linear relations between more concentrated Rangifer spatial use and reductions in graminoid and forb biomass within islands added spatial heterogeneity to long-term patterns identified by the chronosequence. These results support, in part, the hypothesis that Rangifer population persistence on islands is facilitated by successful exploitation of graminoid biomass as winter forage after palatable lichens are decimated. However, the shift from shrubs to graminoids was expected to enhance rates of nitrogen cycling yet rates of net N-mineralization, NH+ 4 pools, and soil d15N declined markedly along the chronosequence and were weakly associated with spatial use within islands. Overall plant and soil patterns were disrupted but responded differently to intermediate (50 yr) and long-term (100 yr) herbivory, and were correlated with distinct stages of irruptive population dynamics. – doi:10.1002/ecs2.1219 URL: http://onlinelibrary.wiley.com/doi/10.1002/ecs2.1219/full [Edit/Delete] [Upload PDF/URL]

[RLL List # 240 / Rec.# 36429] Keywords: ALASKA/ COMMUNITY ANALYSIS/ CLIMATE/ EPIPHYTES/ THRESHOLDS Abstract: Because of their unique physiology, lichen communities are highly sensitive to climatic conditions, making them ideal bioindicators for climate change. Southeast and south-central Alaska host diverse and abundant lichen communities and are faced with a more rapidly changing climate than many more southerly latitudes. We develop sensitive lichen-based indicators for tracking the effects of climate change in south-central and southeast Alaska. Using 196 plots, we model community composition and 12 individual species abundances in relation to synthetic climate variables. Both types of lichen indicator are closely related to the climate variable describing a transition from warm, wet oceanic climates to cooler, drier suboceanic climates. Lichen communities and individual species exhibited thresholds associated with average December minimum temperatures between -10.2 and -7.8°C and annual precipitation between 106 and 172 cm, suggesting rapid turnover with relatively small changes within these ranges. These climate conditions occur close to the coast in northern portions of the region and further inland in southeast Alaska. Because lichen communities in the threshold region may be most sensitive to a changing future climate, they should be targeted for monitoring efforts. – doi:10.1639/0007-2745-117.3.241 Countries/Continents: North America/U.S.A.

[RLL List # 244 / Rec.# 38091] Keywords: FUNGAL COMMUNITIES/ CLIMATIC CHANGES/ SNOW FENCE/ ION TORRENT/ FUNGAL DIVERSITY/ TOOLIK LAKE Abstract: Climate warming leads to more intensive evaporation from the Arctic sea resulting in increased precipitation in the low Arctic, e.g., higher snowfall during winter. Deeper snow keeps the arctic soils warmer and alters soil attributes and vegetation, e.g., increase in nitrogen availability, expansion of shrubs and decline in shade-intolerant lichens and bryophytes. Changes in soil properties and vegetation are expected to influence on saprotrophic and plant-symbiotic fungi, but how increased snow depth affects their community composition remain unknown. In the present work, we used DNA metabarcoding to study the effects of long-term experimental manipulations of snow depth on soil fungal communities in dry heath and moist tussock tundra in Arctic Alaska. We report strong changes in fungal community compositions in the two tundra types, with pronounced declines observed in the majority of fungal functional guilds, including ectomycorrhizal, lichenized, plant pathogenic, saprotrophic and bryophyte-associated species. The observed changes in lichenized and bryophyte-associated fungi are in agreement with previously published above-ground changes, i.e. decrease of lichen and bryophyte cover and diversity. However, the majority of observed trends, including the decline of ectomycorrhizal fungi (that were anticipated to benefit from the expansion of their host plants), suggest that changes in fungal communities do not entirely correspond to and are not primarily driven by shifts in vegetation. Instead, arctic fungal communities appear to exhibit faster turnover that may be influenced by dynamic interactions with numerous biotic and abiotic factors, e.g., soil nutrient cycling and community dynamics in other groups of soil microorganisms. We highlight the importance of “below-ground studies” in assessing ecosystem responses to climatic changes, because faster turnover of microbial communities may be applicable for monitoring early-stage alterations caused by climatic changes.

Without reliable assessment tools, the potential effects of climate and land use changes on these functions remain unclear; therefore, we implemented a novel “Ground Layer Indicator” method as part of the U.S.D.A. Forest Inventory and Analysis (FIA) program. Non-destructive depth and cover measurements were used to estimate biomass, carbon and nitrogen content for nine moss and lichen functional groups among eight contrasted habitat types in Pacific Northwest and subarctic U.S.A. (N ?=? 81 sites). Ground layer cover, volume, standing biomass, carbon content and functional group richness were greater in boreal forest and tundra habitats of Alaska compared to Oregon forest and steppe. Biomass of up to 22769 ± 2707 kg ha-1 (mean ± SE) in upland Picea mariana forests was nearly double other reports, likely because our method included viable, non-photosynthetic tissues. Functional group richness, which did not directly correspond with biomass, was greatest in lowland Picea mariana forests (7.1 ± 0.4 functional groups per site). Bootstrap resampling revealed that thirty-two microplots per site were adequate for meeting data quality objectives. Here we present a non-destructive, repeatable and efficient method (sampling time: ca. 60 min per site) for gauging ground layer functions and evaluating responses to ecosystem changes. High biomass and functional distinctiveness in Alaskan ground layers highlight the need for increased attention to currently under-sampled boreal and arctic regions, which are projected to be among the most active responders to climate change. – doi:10.1639/0007-2745-118.1.032 Countries/Continents: North America/U.S.A.

Alaskana and A. recondita, are described. The ITS rDNA region is used for their molecular characterization. Morphologically, Atla Alaskana is characterized by its rather thick and well-developed whitish grey thallus, and the rather large perithecia having a thalline excipulum. The presence of a thalline excipulum renders it similar to Sporodictyon species; however, in A. Alaskana a distinct zone around the ostiolum is without a thallus and covered only by a thick white pruina. Atla recondita has a thin olivaceous brown thallus and moderately sized, emerging perithecia. It is not possible to identify this species unequivocally as an Atla species only by morphology, and it might well be mistaken for a Polyblastia. A key to all six Atla species, including the two new species, is provided. © 2015 British Lichen Society. Notes: New species: Atla alaskana and Atla recondita.

Much less attention has been given to other groups of organisms, particularly obligate symbiotic organisms. We present the first quantitative assessment of how spatial and environmental variables shape the abundance and distribution of obligate symbiotic organisms across nearly an entire subcontinent, using lichen propagules as an example. Location The contiguous United States (excluding Alaska and Hawaii). Methods We use DNA sequence-based analyses of lichen reproductive propagules from settled dust samples collected from nearly 1300 home exteriors to reconstruct biogeographical correlates of lichen taxonomic and functional diversity. Results Contrary to expectations, we found a weak but significant reverse latitudinal gradient in lichen propagule diversity. Diversity was not impacted by urbanization or human population density. We show that propagules of asexually reproducing species have wider geographical ranges than propagules from sexually reproducing species, likely reflecting the lichenized nature of asexual spores that disperse both the mycobiont and photobiont versus non-lichenized sexual spores, which disperse only the mycobiont. Main Conclusions Our findings of a reverse latitudinal gradient and a relative lack of impact of urbanization on lichen propagules and/or lichen-forming fungal spores suggest that core concepts in biogeography are better informed via consideration of additional patterns from other, less well studied groups of organisms. – doi:10.1111/jbi.12746 URL: http://onlinelibrary.wiley.com/doi/10.1111/jbi.12746/abstract [Edit/Delete] [Upload PDF/URL]

[RLL List # 237 / Rec.# 35920] Keywords: AIR QUALITY/ ALASKA/ BRYOPHYTES/ INVENTORY/ LICHENS/ MONITORING/ VEGETATION/ BRYOPHYTES Abstract: Alaska’s national parks encompass a wide range of habitat types and climate gradients known to support a rich and diverse flora. At such northern latitudes, nonvascular plants, particularly bryophytes and lichens, contribute a significant portion to overall biomass and biodiversity, provide a wide range of ecosystem functions, and can serve as important indicators of air quality and climate change. A number of Alaskan parks have recently completed or are conducting comprehensive inventories that are documenting extraordinary nonvascular plant diversity. Alaska’s Inventory and Monitoring networks have also developed vegetation and air quality vital-sign monitoring programs that include nonvascular plant communities in their baseline sampling. University partnerships have played an important role in contributing to our understanding of nonvascular vegetation communities in Alaska’s national parks. Such collaboration has provided a strong foundation for future studies and has enhanced NPS efforts toward resource management goals.
