Historically the U.S. Forest Service has used uncorrected
aerial photographs to delineate proposed and past management
activities on the land base it manages. Transferring a boundary
from an image not planimetrically correct to a planimetrically
corrected image introduces errors. Positional accuracy of
boundaries affects the number of acres the Forest...
The purpose of this thesis is to analyze an abrupt case of climate change in the past as a means to understand the mechanisms that force climate change. By looking to past analogs of climate change, we hopefully will gain an understanding of these events, which could be used to...
My dissertation concerns two separate issues. The first issue is examined in Essay One, and the second issue is examined in Essays Two and Three.
The first essay develops an economic model of the determination of the rental rate of leased farmland in the United States. Particular attention is placed...
Sustainable management of the world’s forests is a key component for conserving biodiversity, soil and water resources, mitigating climate change, strengthening economies, and promoting sustainable communities and human well-being, now and in the future. While international cooperation is important, the actual policies and management actions that affect forest conditions and...
Rare plant reintroductions are a critical conservation tool for the augmentation of diminishing populations, or re-establishment of extirpated populations. Analysis of reintroduction failures suggests that a sophisticated understanding of species biology, ecology, and habitat is essential for producing self-sustaining rare plant populations. This study sought to generate that background knowledge...
Novel broad-spectrum antimicrobials are a critical component of a strategy for combating antibiotic-resistant pathogens. In this
study, we explored the activity of the broad-spectrum antiviral compound ST-669 for activity against different intracellular bacteria
and began a characterization of its mechanism of antimicrobial action. ST-669 inhibits the growth of three different...
This compilation of theses and dissertations (a part of the OSU Bibliographic Series) for the period 1970-1977 reflects this university's emphasis on research and graduate study. It may be viewed as an indicator of the contributions made to the state of Oregon through graduate study and research at Oregon State...
The European hazelnut, Corylus avellana L., was imported into the U.S. in the late 1800's and is now grown throughout the Willamette Valley in Oregon. A native species of hazelnut, C. cornuta Marshall, is a common shrub found in forested areas of the Pacific Northwest. Foliage of both C. avellana...
Communication in purposeful human activity systems plays a critical role in the design, management, and change management of these systems. However, its impact on and integrated nature in purposeful human activity systems is not well understood from a holistic viewpoint. In addition, a formal definition and methodology for identifying signs...
