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...

Beaver ecology on the west Copper River Delta, Alaska

Creator:: Cooper, Erin E.
Abstract:: Since the 1964 earthquake and geologic uplift, beavers (Castor canadensis) have expanded their historic range from the inland (outwash plain) Copper River Delta, Alaska to the once tidally influenced areas of the outer area (uplifted marsh). The uplift presents a unique opportunity to observe beaver expansion, habitat selection and influence...

Influence of habitat characteristics on Greater sage-grouse reproductive success in the Montana Mountains, Nevada

Creator:: Rebholz, James L.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) populations have declined across their geographic range during the last century. They were once widespread throughout the Intermountain West, but lower annual productivity, likely caused by degradation and loss of suitable habitat, has greatly reduced their distribution and population densities. Habitat used for reproduction has been...

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...

Food habits, dietary overlap and gastric evacuation rates of rockfishes (genus Sebastes)

Creator:: Brodeur, Richard D.
Abstract:: Euphausiids constituted the major food of five co-occuring species of rockfishes (Sebastes spp.). Copepods, decapods, cephalopods, amphipods, fishes and other pelagic prey were also consumed but were less important to the overall diet. Two species, S. flavidus and S. diploproa, were relatively euryphagous, utilizing a high number of prey taxa....

Test fixture characterization for high-frequency silicon substrate parasitic extraction

Creator:: Tabalujan, Andrew R.
Abstract:: At frequencies exceeding 1-2 GHz, the reactive nature of a silicon substrate must be accounted in the substrate network models used in substrate coupling simulation. High-frequency substrate models, containing reactive components, must be validated through high-frequency network analyzer measurements. Prior fabricated test fixtures have been modified to enable high-frequency (up...
