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...

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...

Marine habitat use of black-footed and Laysan albatrosses during the post-breeding season and their spatial and temporal overlap with commercial fisheries

Creator:: Fischer, Karen Naess
Abstract:: Incidental bycatch in commercial fisheries has been identified as a threat to black-footed albatrosses (Phoebastria nigripes) and Laysan albatrosses (P. immutabilis). Effective long-term conservation of these albatrosses necessitates a thorough understanding of their marine distribution, which marine habitats are selected during foraging, and where they are most likely to interact...

Marine conservation in Latin America and the Caribbean : an analysis of marine protected areas (MPAs)

Creator:: Guarderas, A. Paulina
Abstract:: Coastal and marine ecosystems in Latin America and the Caribbean are undergoing a rapid and drastic transformation. Dense human populations are concentrated in coastal areas, leading to increased coastal development, destruction of near-shore habitats, pollution, and overexploitation of marine resources. For most Latin American and Caribbean countries, the deterioration of...

Analysis of needs-based proposal for a workshop on coastal resources management for specialists from Mexico and the US

Creator:: Hobgood, Nick
Abstract:: Building institutional and human capacity for integrated coastal zone management (ICZM) is increasingly recognized as critical to the future of sustainable development in coastal states. Agenda 21 of the UNCED conference has underscored the urgency of capacity building for ICZM as have other international bodies such as the North American...

Characterization of the near-field flow structure of an acoustically self-excited jet in a large enclosure using particle image velocimetry (PIV)

Creator:: Tobias, Jason A.
Abstract:: An experimental study of the near-field flow structure produced by an incompressible turbulent Acoustically Self-Excited Jet (ASEJ) in a large enclosure using Particle Image Velocimetry (PIV) is presented. The salient feature of this jet is that it provides an increase in near-field mixing and turbulence without additional external power input....

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...
