Dissolved nitrogen in surface waters and nitrogen mineralization in riparian soils within a multi-land use basin

Creator:: Evans, Daniel M.
Abstract:: The growing population of Oregon’s Willamette River Basin places an increasing demand on the basin’s surface waters. Watershed-scale research addressing spatial trends of dissolved nitrogen (DN) and its relationship with landuse and soil N dynamics, such as N mineralization, is sparse in the Willamette Basin. I measured DN along 124...

Fire ecology of ponderosa pine and the rebuilding of fire-resilient ponderosa pine ecosystems

Creator:: Fitzgerald, Stephen Arthur
Abstract:: The ponderosa pine ecosystem of the West have changed dramatically since Euro-American settlement 140 years ago due to past land uses and the curtailment of natural fire. Today, ponderosa pine forests contain over abundance of fuel, and stand densities have increased from a grange of 49-124 trees per ha (20-50...

Hydrology and geomorphic evolution of basaltic landscapes, High Cascades, Oregon

Creator:: Jefferson, Anne (Anne Jarvis)
Abstract:: The basaltic landscapes of the Oregon High Cascades form a natural laboratory for examining how geologic setting and history influence groundwater flowpaths, streamflow sensitivity to climate, and landscape evolution. In the High Cascades, highly permeable young basaltic lavas form extensive aquifers. These aquifers are the dominant sources of summer streamflow...

Conserved properties in the metagenome of a large bacterioplankton population

Creator:: Wilhelm, Larry John
Abstract:: Candidatus Pelagibacter ubique is the first cultured representative of the SAR11 clade, a clade that is found throughout the oceans and accounts for approximately 25% of all bacterial cells [1]. It has a streamlined genome that is the smallest of any known free-living organism. In this study the complete genome...

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...

Design and preliminary characterization of thermally-actuated pumps utilizing Marangoni and Leidenfrost effects

Creator:: Sedler, Stephen Joseph
Abstract:: Design and preliminarily characterization of two thermally-actuated pumps is presented in this thesis. The unique feature of both pumps is the presence of periodic asymmetrical structures on the channel walls. Two heat transfer effects are used with surface asymmetry to generate forces that drive the fluid in a preferential direction...

A physical and chemical characterization of stream water draining three Oregon Coast Range catchments

Creator:: Hale, V. Cody
Abstract:: Few studies have examined both long-term and fine-scale spatial variations in water quality of small streams in the Pacific Northwest. As such, a case study was conducted to determine if current physical and chemical properties of water in three streams located in the Oregon Coast Range differed from historically measured...

Belowground carbon storage and soil organic matter quality following fertilizer and herbicide applications in ponderosa pine plantations along a site-quality gradient in northern California

Creator:: McFarlane, Karis J., 1979-
Abstract:: Belowground carbon (C) storage and quality of soil organic matter (SOM) in forest soils have implications for sustainable forest management and C sequestration, but how these pools change in response to management is poorly understood. I investigated whether fertilization and competing vegetation control, applied alone or in combination early in...

Methods for multi-spatial scale characterization riparian corridors

Creator:: Moser, Thomas J., Lindeman, Dale R., Wigington, P.J., Schuft, Michael, and Van Sickle, John
Abstract:: This paper describes the application of aerial photography and GIS technology to develop flexible and transferable methods for multi-spatial scale characterization and analysis of riparian corridors. Relationships between structural attributes of riparian corridors and indicators of stream ecological conditions are not well established. As part of a research project focused...
