The end of the Cold War brought about changes within international political relations that resulted in expanded interest in global civil society. Such developments, like globalization and democratization, have encouraged the growth of social and political organizations. Political scientists have found that these inter-governmental and non-governmental organizations have a significant...
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...

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...

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...

The purpose of this investigation was to test two hypotheses.
The first hypothesis interprets allochthonous rocks in the southern
Pinyon Range to lie on the Devonian Nevada Group. The second
hypothesis interprets allochthonous rocks to lie on the Mississippian
Dale Canyon Formation. Evidence presented here supports the second
hypothesis.
During...

AN ABSTRACT OF THE THESIS OF
Robert Vincent Visconti for the
Paleozoic dolomites, limestones, and detrital clastic rocks
were mapped in the Bellevue Peak 15 minute quadrangle in the
southern Mahogany Hills, Nevada. Sedimentary rock units in this
area represent shallow-shelf eastern assemblage deposits.
Shallow-shelf carbonates characterized deposition from at
least Ordovician through Late Devonian time, when clastics derived
from the...
