Lichen response to the environment and forest structure in the western Cascades of Oregon

Creator:: Martin, Erin P.
Abstract:: Lichens are an important part of the biota in western Oregon forests, where they perform valuable ecological roles and contribute significantly to biodiversity. Lichens in western Oregon are threatened by a number of factors including air pollution and land use practices. If we wish to maintain the persistence of lichens...

Lichen Functional Trait Variation Along an East-West Climatic Gradient in Oregon and Among Habitats in Katmai National Park, Alaska

Creator:: Spickerman, Kaleigh
Abstract:: Functional traits of vascular plants have been an important component of ecological studies for a number of years; however, in more recent times vascular plant ecologists have begun to formalize a set of key traits and universal system of trait measurement. Many recent studies hypothesize global generality of trait patterns,...

Community gradients of Arctic macrolichens in relation to succession, grazing and the environment

Creator:: Holt, Emily A.
Abstract:: The purpose of this dissertation was to define macrolichen community gradients in relation to succession, grazing and the environment. First, species scores indicating when macrolichen species appeared following disturbance were derived from the literature. Weighted averaging of these data with a community matrix created a successional score for each sample...
Resource Type:: Dissertation
Full Text:: . These scores are surrogates for community age for subsequent analyses. I then described lichen

Biological soil crusts in forested ecosystems of southern Oregon : presence, abundance and distribution across climate gradients

Creator:: Olarra, Jennifer A.
Abstract:: In arid and semi-arid deserts, soils are commonly covered with biological soil crusts. The study of arid biocrusts and their ecological function has become increasingly common in the literature over the last several decades. Interestingly, no mention is made of biological soil crusts in forested ecosystems, raising the question as...

Lichen communities and caribou habitat in Denali National Park and Preserve, Alaska, USA

Creator:: Nelson, Peter R.
Abstract:: Lichens play many important roles in subarctic terrestrial ecosystems by fixing nitrogen, colonizing rock and gravel, stabilizing otherwise bare soil, adding significantly to vegetation biodiversity and serving as the primary food for caribou in the winter. In these chapters, I analyzed lichen community and ecological trait structure along environmental gradients,...

Multiscale habitat electivity and movement patterns by adult spring chinook salmon in seven river basins of northeast Oregon

Creator:: Price, David M.
Abstract:: I examined habitat electivity and movement patterns of adult spring chinook salmon at microhabitat and channel unit spatial scales, and seasonal to annual temporal scales in seven streams in the Grande Ronde, John Day, and Imnaha basins. The objective was to compare habitat use and availability among streams, channel units,...

Stem sapwood water transport and storage strategies in three conifers from contrasting climates

Creator:: Barnard, David M.
Abstract:: The state of Oregon has two distinct climate types bisected by the crest of the Cascade Mountain range. The western side of the Cascades experiences high levels of precipitation and mild temperatures due to the maritime influence of the Pacific Ocean, while the eastern side lies in the rain shadow...

Grazing relationships of elk, deer and cattle on seasonal rangelands in northeastern Oregon

Creator:: Sheehy, Dennis Patrick
Resource Type:: Dissertation
Full Text:: . Martin Vavra Rangelands at the juncture of grass steppe and forest communities in northeastern Oregon

New insights on an old topic : understanding the effects of forest harvest on trout in the context of climate

Creator:: Penaluna, Brooke E.
Abstract:: Studies of the effects of forest harvest on streams and fish have a long history in the Pacific Northwest. Results of this work have prompted development of new forest harvest practices that are more protective of these resources, but the effectiveness of these new practices has not been fully evaluated....
