The mechanism of transsulfuration and the role of cystathionine
in the biosynthesis of methionine in yeast were investigated.
Saccharomyces were shown to accumulate cystathionine by use
of the ³⁵S labeled compound.
Cell-free extracts of the wildtype clone as well as methionine
auxotrophs were shown to cleave cystathionine. The enzymatically
produced...
The purpose of the study was to explore a needs
assessment method for suggesting target-based training
interventions for managing conflict between the resource
user/interest groups in Oregon's riparian zones. An
instrument was developed and then validated by an expert
panel. The questionnaire addressed three potential
conflict management factors: multiple-use orientation,...
The purpose of this study was to develop and validate a self-esteem inventory
for Thai college women. Research questions included whether or not the developed
inventory proved to be unidimensional or multidimensional and, if the
latter proved to be the case, how many dimensions underlie the construct. The
item pool...
The thesis analyzes the demographic, attitudinal and
behavioral characteristics of animal rights activists,
placing them in the context of resource policy. It is
argued that the animal rights movement combined the
Victorian critique of empiricism with a reaction to
modernity that was characteristic of other contemporary mass
movements. Animal rights...
Coastal Douglas-fir (Pseudotsuga menziesii var menziesii) forests are extensive west of the crest of the Cascade Mountains in Oregon and Washington and are renowned for their productivity, biodiversity, and the ecosystem services they provide. Increasing wildfire activity in recent years including the extensive 2020 Labor Day fires, and a warming...
I examined the relative roles of biotic and abiotic factors in structuring redband trout
Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the
relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...
In the United States, many of the thorniest natural resource conflicts occur on private lands. This is especially true in the Willamette Valley of Western Oregon where the hallmark habitat type, Oregon white oak woodland and savanna, is imperiled. Almost exclusively found on private land, Oregon white oak is threatened...
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...
