Climate and terrestrial vegetation have had mutual feedbacks for nearly five hundred million years, yet both are now departing from recent historical norms, with uncertain implications for forest ecosystems. This dissertation outlines the current and potential future climate responses of lichen and bryophyte communities in the United States as part...

The 1995/96 reintroduction of gray wolves (Canis lupus) into Yellowstone National Park
after a 70 year absence has allowed for studies of tri-trophic cascades involving wolves, elk
(Cervus elaphus), and plant species such as aspen (Populus tremuloides), cottonwoods (Populus
spp.), and willows (Salix spp.). To investigate the status of this...

Terrestrial lichen biomass is an important indicator of forage availability for caribou in northern regions, and can indicate
vegetation shifts due to climate change, air pollution or changes in vascular plant community structure. Techniques for
estimating lichen biomass have traditionally required destructive harvesting that is painstaking and impractical, so we...

Plagiobothrys hirtus is Oregon’s top priority for endangered plant species recovery, and the wetlands of Douglas County provide the only habitat for this plant in the world. The goal is to downlist this species from endangered to threatened, and in order to do that, existing populations must be protected, and...

Tumours arising from the dorsal surface of the tongue occurred in 3 horses from 14-23 years of age. Tumours were surgically excised at a referral hospital (1 case) and on the farm (2 cases) and submitted for histopathology. All tumours were multilobular and composed of vaguely nested, bland, oval to...
