Plant community recovery after high severity wildfire and post-fire management in the Klamath Region

Creator:: Lopez Ortiz, Maria Jose
Abstract:: Disturbance and microclimate interact to play a central role influencing the composition and structure of plant communities. In this thesis, I examined plant community composition and structure twenty years after high severity wildfires with and without post-fire management (salvage logging, fuel treatment, tree planting, and shrub release) under contrasting microclimatic...

Predicting channel stability in Colorado mountain streams using hydrobiogeomorphic and land use data : a cost-sensitive machine learning approach to modeling rapid assessment protocols

Creator:: Morét, Stephanie L.
Abstract:: Natural resource data are typically non-linear and complex, yet modeling methods often utilize statistical analysis techniques, such as regression, that are insufficient for use on such data. This research proposes an innovative modeling method based on pattern recognition techniques borrowed from the field of machine learning. These techniques make no...

How the animals found their places : pattern detection, experimentation, and epistemology in a high desert stream fish assemblage

Creator:: White, Seth Michael
Abstract:: 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...

Predicting county-level food insecurity and hunger in Oregon

Creator:: Grussing, Jay D.
Abstract:: Oregon’s high hunger and food insecurity rates have been a concern throughout the last decade. These high rates earned Oregon the dubious distinction as the most food insecure with hunger state in the late 1990’s. While Oregon’s ranking has improved in recent years, our understanding of why Oregon ranked so...

The praxis of cultural competence in medical education : using environmental factors to develop protocols for action

Creator:: Stohs, Sheryl Magee
Abstract:: Cultural competence is a topic that concerns social scientists and medical anthropologists who pay attention to demographic changes and health disparities. This study demonstrates practical approaches to developing cultural competence in medical education by using factors from the social environment to develop protocols for action. With current concerns in domestic...

The relationship between income and food insecurity : the role of social support in rural and urban Oregonians

Creator:: De Marco, Molly M.
Abstract:: Millions of U.S. households experienced hunger in 2005 and millions more experienced food insecurity. Previous research indicates that low-wage work and little social support contribute to food insecurity. Research also suggests that individuals cope by finding alternate food sources and drawing on social support. Further, researchers have found that rural...

Sustainability of a forest preservation project in India : the case of the Kalakad Mundanthurai Tiger Reserve

Creator:: Balasubramanian, Maniselvan
Abstract:: Numerous development projects are implemented in developing countries to attain economic and ecological development. However, in most cases, the encouraging results observed during the implementation phase terminated with the project period, raising concerns on these projects' sustainability after the project period has ended. This study focuses on this sustainability issue...

Stand development after 20-years of growth in Douglas-fir and red alder mixtures

Creator:: Garrelts, Brennan T.
Abstract:: This study examines the long-term role of interference on stand development of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) and red alder (Alnus rubra Bong.) planted mixtures in the Central Cascades of Oregon, USA. The two species are common associates in naturally regenerated and planted conifer stands in the Pacific Northwest. Due...

The influence of biological characteristics on fisheries co-management : a game theory perspective

Creator:: Trisak, Jiraporn
Abstract:: Co-management is considered an alternative approach to fisheries management, however, not all co-managed fisheries have been successful. Most studies discussing the success and failure of co-management have emphasized economic and social attributes of success and failure, such as fishery rights and institutional arrangements. The effect on co-management of biological characteristics,...
