Mat-forming “ground layers” of mosses and lichens often have functional impacts disproportionate to their biomass, and are responsible for sequestering one-third of the world's terrestrial carbon as they regulate water tables, cool soils and inhibit microbial decomposition. Without reliable assessment tools, the potential effects of climate and land use changes...

The market sampling program for Dover, English and petrale sole and Pacific ocean perch continued. Bottomfish landings were sampled at Astoria and Coos Bay. Dover sole research cruises were made in August 1967 and February 1968. Results on juvenile distribution are discussed. A tagging cruise for Dover sole was completed...
Parmelina quercina is a well-studied foliose macro-lichen found on rocks and trees in the Northern Hemisphere. Recent studies support multiple species within P. quercina based on material from Europe, North America and western Asia. The identities of Parmelina quercina s.lat. reported from eastern Asia and Alaska remain unknown. We compared...
In the mountains of central and southern California, high elevation wilderness areas lack epiphytic lichens that can be used to inform us about atmospheric deposition in multiple ways. Epiphytic lichens are capable of accumulating elements proportionally to the local atmospheric concentration, establishing them as commonly used biomonitor of key elements....
Rinodina pallidescens is described as a new species, endemic to southern Alaska. Rinodina buckii and R. oregana are discussed in terms of their range extensions and possible phytogeographic histories.
We describe Umbilicaria nodulospora, a distinctive new species occurring on steep rock faces on old lava flows in California and Oregon. The species is unusual among lichenized ascomycetes in consistently having one or two shallowly bulging knobs at one end of each ascospore, suggesting a T, Y, or L shape;...
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...

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...

A new species belonging to the lichen genus Physconia is described from Alaska and the Canadian and American Rocky Mountains and adjacent forested regions. It is also reported from China, Nepal, India and Siberia. The new species, Physconia labrata, is superficially similar to P. perisidiosa, but can be distinguished by...
We monitored the distribution, abundance and productivity of the federally threatened Western SnowyPlover (Charadrius nivosus nivosus) along the Oregon coast from 5 April – 31 August 2016. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North and South Tahkenitch...
