Mark E. Fenn,Jill S. Baron,Edith B. Allen,Heather M. Rueth,Koren R. Nydick,Linda H. Geiser,William D. Bowman,James O. Sickman,James O. Sickman,Thomas Meixner,Dale W. Johnson,Peter Neitlich +11 more
TL;DR: In the western United States vast acreages of land are exposed to low levels of atmospheric nitrogen (N) deposition, with interspersed hotspots of elevated N deposition downwind of large, expanding metropolitan centers or large agricultural operations.
Journal ArticleDOI
Conditional vulnerability of plant diversity to atmospheric nitrogen deposition across the United States
Samuel M. Simkin,Edith B. Allen,William D. Bowman,Christopher M. Clark,Jayne Belnap,Matthew L. Brooks,Brian S. Cade,Scott L. Collins,Linda H. Geiser,Frank S. Gilliam,Sarah E. Jovan,Linda H. Pardo,Bethany K. Schulz,Carly J. Stevens,Katharine N. Suding,Heather L. Throop,Donald M. Waller +16 more
TL;DR: It is demonstrated here that negative relationships between N deposition and species richness are common, albeit not universal, and that fine-scale processes can moderate vegetation responses to N deposition.
Journal ArticleDOI
Air pollution and climate gradients in western Oregon and Washington indicated by epiphytic macrolichens.
Linda H. Geiser,Peter Neitlich +1 more
TL;DR: This first application of non-metric multidimensional scaling to a large-scale, framework dataset, modeled lichen community response to air quality and climate gradients at 1416 forested 0.4 ha plots, finding worst air scores occurred in urban-industrial and agricultural valleys.
Journal ArticleDOI
Forest lichen communities and environment–How consistent are relationships across scales?
TL;DR: In this article, the authors used global NMS ordination of plots based on species abundance to extract major axes of variation in community composition and compared between geographic scales for the two regions.
Journal ArticleDOI
Sources and deposition of polycyclic aromatic hydrocarbons to Western U.S. national parks.

TL;DR: The results suggest that topographic barriers influence the atmospheric transport and deposition of PAHs in high-elevation ecosystems and that PAH sources to these national park ecosystems range from local point sources to diffuse regional and global sources.
