An exploratory economic analysis of the effects of regulation, hunter participation and harvest on migratory bird management

Creator:: Dell, Randal Scott
Abstract:: Waterfowl and the places they inhabit provide numerous economic benefits to society. The financial and other resources provided by waterfowl hunters to secure and protect waterfowl habitat are a major force for wetland protection, as guided under the North American Waterfowl Management Plan. However, the habitat and population objectives established...

Aqueous Corrosion and High Temperature Oxidation in Supercritical Carbon Dioxide Environments

Creator:: Teeter, Lucas
Abstract:: The corrosion resistance of steels and nickel based alloys was investigated in supercritical CO2 (sCO2). Two types of experiments were conducted. The first set of experiments were conducted in a low temperature aqueous environment to simulate conditions that would exist in direct sCO2 power cycle low temperature heat exchangers. The...

Farm and community-level impacts of irrigation water supply reductions : a case study of Malheur County, Oregon

Creator:: Wyse, Barbara J.
Abstract:: Agricultural water supplies are becoming increasingly uncertain in the western United States due to rising demand from competing water users, environmental restrictions on surface water withdrawals due to water quality and endangered species concerns, and, potentially, climate-induced hydrological changes. Since many rural areas in the West depend economically upon irrigated...

Characterizing early-seral competitive mechanisms influencing Douglas-fir seedling growth, vegetation community development, and physiology of selected weedy plant species

Creator:: Dinger, Eric J.
Abstract:: Three studies were conducted to characterize and present early-seral competition between Douglas-fir seedlings and the surrounding vegetation communities during Pacific Northwest forest establishment. The first experiment served as the foundation for this dissertation and was designed to quantify tradeoffs associated with delaying forest establishment activities by introducing a fallow year...

Seed bank response to juniper expansion in the semi-arid lands of Oregon, USA

Creator:: Duncan, Corinne M.
Abstract:: Expansion of Juniperus occidentalis into the sagebrush steppe has resulted in significant changes in understory composition. A consequence of increased J. occidentalis dominance may be a depletion of the seed bank. The potential for depletion is problematic because a reduction in the amount of species available from the seed bank...

Hybridization between Castilleja levisecta and C. hispida : Implications for Pacific Northwest Prairie Management

Creator:: Sandlin, Isaac J., III
Abstract:: Conservation conflicts may develop on restoration sites with multiple species recovery objectives. For example, on Pacific Northwest prairies, the co-planting of the diploid cytotype of the common native wildflower Castilleja hispida with the endangered wildflower C. levisecta has resulted in putative Castilleja hybrids on restoration sites, prompting fears that genetic...

Patterns of tree establishment and vegetation composition in relation to climate and topography of a subalpine meadow landscape, Jefferson Park, Oregon, USA

Creator:: Zald, Harold S. J.
Abstract:: The forest alpine tundra ecotone (FTE, also known as alpine treeline or subalpine parkland), is a conspicuous feature of mountain landscapes throughout the world. Climate change-driven increases in temperature are believed to result in FTE movement and tree invasion of subalpine meadows, which have been documented throughout the Northern Hemisphere...

On the Role of Particle Size Distribution in Selective Laser Melting of 316L Stainless Steel

Creator:: Coe, Hannah G.
Abstract:: Selective laser melting (SLM) is an additive manufacturing (AM) process that uses a laser beam to melt metal powder as it is spread onto the build surface using a roller or scraper, followed by rapid solidification to manufacture a 3D component, one layer at a time. In SLM process, density...

Making Electric Vehicles Accessible: A Program Evaluation of California's Clean Vehicle Assistance Program

Creator:: Diaz, Alexa R.
Abstract:: Transportation contributes approximately 41 percent of California’s greenhouse gas emissions and 27 percent of national greenhouse gas emissions (CARB, 2019, EPA, 2017). In response to climate change concerns, stakeholders have encouraged the use of electric and hybrid vehicles through tax credits, rebates, and education campaigns. Environmental and transportation justice groups...

Corrosion Resistance of Alloys in Seawater and Supercritical Carbon Dioxide Environments

Creator:: Repukaiti, Reyixiati
Abstract:: The corrosion resistances of several alloys were investigated to optimize performance and cost in seawater and supercritical CO2 environments. Many alloys are prone to corrosion in seawater and/or supercritical CO2 containing impurity environments. Exposure and electrochemical experiments were conducted in both environments to evaluate alloys’ corrosion resistance. In seawater corrosion...
