Extracting gradients from community data with multiple stressors and empty plots: A case study and simulations Open
Ecological community data are used to infer levels of environmental stressors; for example, epiphytic lichen communities can be used to estimate levels of air pollutants. If stressors are so severe that the community of interest disappears…

A new species of Diploschistes (Lecanoromycetes) occurring on Stereocaulon from the Pacific Northwest of North America Open
We describe Diploschistes stereocaulorum as a new species of lichenized fungi growing on phyllocladia and stalks of Stereocaulon in the Pacific Northwest of North America. The larger ascospores of this species, the absence of a noticeable …

Stereocaulon tomentosoides, a new combination for a western North American endemic species with cyanobiont and chemotype polymorphisms Open
Based on resampling the type locality and surrounding regions, along with phylogenetic analysis of molecular data, we elevate Stereocaulon sasakii var. tomentosoides to the species level, while we treat S. sasakii var. simplex as an enviro…

An Annotated Checklist of Lichens of the Opal Creek Wilderness and Adjacent Areas: a Pre-Fire Baseline Open
In 2020 the Beachie Creek Fire burned a large area of forest in the northern Oregon Cascade Range including public and private land and much of the Opal Creek Wilderness. We compiled a baseline data set from various sources of the lichens …

<i>Sinuicella denisonii</i>, a new genus and species in the<i>Peltigeraceae</i>from western North America Open
The new genus Sinuicella , an early successional lichen, was found on bare soil in Oregon, USA. The thallus is minute fruticose, grey to nearly black, branching isotomic dichotomous, branches round, 20–90 μm wide in water mount. The cortex…

Biodiversity and ecology of lichens of Kenai Fjords National Park, Alaska Open
We inventoried lichens in Kenai Fjords National Park in Alaska, USA We assembled the known information on occurrence and ecology of lichens in this park by combining field, herbarium, and literature studies. Our results provide baseline da…

Lichenometric Dating of Historic Inscriptions on a Rock Outcrop in Coastal Oregon Open
We estimated the age of inscriptions on a rock outcrop by estimating the ages of lichens that had overgrown the inscriptions. The inscriptions are considered to be historically important, potentially representing some of the earliest Europ…

Novel climates reverse carbon uptake of atmospherically dependent epiphytes: Climatic constraints on the iconic boreal forest lichen <i>Evernia mesomorpha</i> Open
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 epiphyt…

Estimating age of rock cairns in southeast Alaska by combining evidence from successional metrics, lichenometry, and carbon dating Open
We estimated ages of rock cairns in alpine tundra in southeast Alaska by combining information from three general classes of methods, each of them imperfect, but considered together providing better estimates than any of the three alone. W…

Limitations of Species Delimitation Based on Phylogenetic Analyses: A Case Study in the Hypogymnia hypotrypa Group (Parmeliaceae, Ascomycota) Open
Delimiting species boundaries among closely related lineages often requires a range of independent data sets and analytical approaches. Similar to other organismal groups, robust species circumscriptions in fungi are increasingly investiga…

Time trumps habitat in the dynamics of an avian community Open
Predictions of change in avian biodiversity often fail to account for the natural dynamism of species assemblages. Information from historical datasets can be useful indicators of how avian communities may change in the future. However, si…

Non-Native Plant Invasion along Elevation and Canopy Closure Gradients in a Middle Rocky Mountain Ecosystem Open
Mountain environments are currently among the ecosystems least invaded by non-native species; however, mountains are increasingly under threat of non-native plant invasion. The slow pace of exotic plant invasions in mountain ecosystems is …

Response of the nitrogen‐fixing lichen <i>Lobaria pulmonaria</i> to phosphorus, molybdenum, and vanadium Open
Nitrogen‐fixing lichens (cyanolichens) are an important source of nitrogen (N) in Pacific Northwest forests, but limitation of lichen growth by elements essential for N fixation is poorly understood. To investigate how nutrient limitation …

Evolution of complex symbiotic relationships in a morphologically derived family of lichen‐forming fungi Open
Summary We studied the evolutionary history of the Parmeliaceae (Lecanoromycetes, Ascomycota), one of the largest families of lichen‐forming fungi with complex and variable morphologies, also including several lichenicolous fungi. We assem…
