Susceptibility of juvenile salmonids to avian predation : Are Caspian terns and double-crested cormorants only taking the sick and injured?

Creator:: Hostetter, Nathan J.
Abstract:: The ability to non-destructively assess fish condition and subsequently track fish behavior and survival can be vital in understanding natural and anthropogenic stressors and sources of mortality, especially in populations of fish listed as threatened or endangered. I investigated the use of a quick, non-lethal, external examination technique to assess...

Binary stochastic media transport : a coupled mesh based method

Creator:: Barnett, Nathan A.
Abstract:: Transport in a binary stochastic media has been an area of interest for many applications over the past three decades. Many different methods have been attempted, most based on the Levermore-Pomraning coupled transport model. However, this method has never been able to correctly solve problems where a large amount of...

Response of needle-litter decomposition and soil nitrogen mineralization to logging-debris manipulation and competing vegetation control in western Oregon and Washington

Creator:: Meehan, Nathan Andrew
Abstract:: Growing societal demand for forest products is pressuring managers to increase productivity from a finite land area, and it is expected that increased supply will come mostly from expansion of intensively managed stands. The USDA Forest Service and numerous collaborators created the Long-Term Soil Productivity (LTSP) network of research sites...

Effects of estuarine circulation patterns and stress on the migratory behavior of juvenile salmonids (Oncorhynchus sp.)

Creator:: Truelove, Nathan Kobun
Abstract:: For the first objective of this thesis, we attempt to understand the role of water flow and directionality in determining steelhead (Oncorhynchus mykiss) and spring/summer and fall Chinook (O. tschawytscha) migration patterns within the Columbia River Estuary and plume by integrating recent advances in biotelemetry and environmental observation and forecasting...

Ecology of Columbian black-tailed deer fawns in western Oregon

Creator:: Pamplin, Nathan P.
Abstract:: Little is known about Columbian black-tailed deer (Odocoileus hemionus columbianus) because of their elusive nature and the logistical difficulty of studying them in densely forested and mountainous terrain. The Oregon Department of Fish and Wildlife has identified fawn survival as an important gap in the current knowledge of demography and...

Sediment storage in a headwater valley of the Oregon Coast Range : erosion rates and styles and valley-floor capacitance

Creator:: Casebeer, Nathan E.
Abstract:: This study is part of the effort to quantify sediment budgets and understand the geomorphic evolution of steep mountains where debris flows are the dominant agent of upland erosion. Observations indicate that headwater basins in the Oregon Coast Range (OCR) can store a large amount of sediment, mostly from debris...

Effects of body size on the survival and timing of emigration of newly metamorphosed Northern Red-legged frogs

Creator:: Chelgren, Nathan D.
Abstract:: The purpose of this study was to investigate the survival and movements of newly metamorphosed Northern Red-legged frogs (Rana aurora aurora) as they emigrated from two ephemeral breeding ponds. Quantifying survival and movement rates will be important to our understanding how changes to terrestrial and aquatic systems affect behavior and...

Metallic nanoscale conductors

Creator:: Nebergall, Nathan Sky
Abstract:: A new, reproducible method of using electromigration to form metallic nano-conductors is developed using gold and a tin-silver alloy. Measurements revealed a quantization of the electrical conductance consistent with the theory of quantum conductance. The theory of quantum conductance is applied to show that a nano-conductor with a cross-section of...

The Shade Credit Incentive Landscapes of the McKenzie/Willamette Confluence

Creator:: Shaub, Nathan C.
Abstract:: Increasing population and land use decisions have had a negative effect on the aquatic ecosystems in the Willamette River Basin. One result is elevated temperatures in many of the Basin’s streams, which adversely affect the fish that live in these streams. There are several regulatory mechanisms in place to improve...

Automated model parameter extraction for noise coupling analysis in silicon substrates

Creator:: Peterson, Brett
Abstract:: An automated method, requiring the fabrication of a small set of test structures, efficiently extracts the coefficients of Z-parameter based macromodels. The extraction approach has been validated for both heavily and lightly doped substrates and can be applied to a variety of technologies. After the parameters of a macromodel have...
