Trickle-down ecohydrology : complexity of rainfall interception and net precipitation under forest canopies

Creator:: Allen, Scott T.
Abstract:: Rainfall interception is a primary control over the moisture input to a forested ecosystem through the partitioning of precipitation into throughfall, stemflow, and an evaporated component (i.e. the interception loss). Rainfall interception is a spatially and temporally varying process at multiple scales, but heterogeneity in interception processes are poorly understood...

An interindustry analysis of the importance of grazing on federal lands to the economy of Grant County, Oregon

Creator:: Bromley, Daniel W., 1940-
Abstract:: Use of federal lands for commercial and recreational activities contributes significantly to the economic stability of many rural areas. Recent increases in demand for recreational use have created conflicts between uses and among users. Some are questioning the use of public land for private gain. The seemingly low grazing fees...

Escape in Time: Phenology Mitigates Impacts of the Introduced Cinnabar Moth, Tyria jacobaeae, on Native Herb Senecio triangularis in Western Oregon

Creator:: Lunde, A. Katarina
Abstract:: Classic biological control can be a powerful option for those tasked with managing biological invasions; however, some biocontrol releases lead to non-target attack – feeding, damage or development on species other than the target species. The cinnabar moth, Tyria jacobaeae L. (Lepidoptera: Erebidae) was introduced to Western Oregon as a...

Application of Self-Assembled Monolayers to InGaZnO Thin Film Transistors

Creator:: Motley, Joshua R.
Abstract:: Investigations on the application of self-assembled monolayers (SAM) to indium gallium zinc oxide (IGZO) thin film transistors (TFT) for fabrication and channel modification are presented. The back channel of IGZO thin film transistors can be modified by the absorption of self-assembled monolayers. The electrical properties of the IGZO exposed back...

Novel icosanoids from the red marine alga Farlowia mollis

Creator:: Solem, Michele Lee
Abstract:: Farlowia mollis is a marine red alga that grows in the intertidal region along the coast of Oregon. We began studying the chemistry of this alga after a survey of Oregon seaweeds revealed possibly interesting chemistry and antimicrobial activity in its crude organic extract. Over the past three years the...

The role of Salmonella typhimurium type three secretion system (T3SS) and effector proteins in chromatophore cell response.

Creator:: Farhad, Mohammad
Abstract:: Bacterial contamination of food poses a great risk to human health worldwide. A chromatophore cell-based biosensor, utilizing B. splendens erythrophore cells, is an emerging technology that has shown potential to detect bacterial toxicity based on function-dependent mechanisms. Previous studies have investigated the response of erythrophore cells to foodborne pathogens, pesticides,...

Expression of secondary metabolites following manipulations of the C:N ratio in spotted knapweed, Centaurea maculosa Lam.

Creator:: Brodhagen, Marion L.
Abstract:: Spotted knapweed, Centaurea maculosa Lam. (Compositae) is an extremely successful introduced weed species in the northwestern United States. Multiple factors may be responsible for its success, including chemical defense. Two different types of putative chemical defense agents are the focus of this thesis. The first is a bitter-tasting sesquiterpene lactone,...

Drug resistance, source, and environmental factors that influence fecal coliform levels of Tillamook Bay

Creator:: Kelch, William James
Abstract:: In order to determine the source of bacteria in Tillamook Bay, Oregon, water samples were collected monthly for six months during the rainy season from October 1975 through March 1976 from the bay and its tributaries, the Kilchis, Trask, Tillamook, and Wilson Rivers. Fecal coliform levels of these samples were...

Taper, crown, and volume responses of a coastal Oregon Douglas-fir stand to sulfur treatments for control of Swiss needle cast

Creator:: Younger, Nicole L.
Abstract:: For nearly two decades, foresters in the Oregon Coast Range have been witnessing a substantial decease in Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco.) vigor and growth, caused by Swiss needle cast (Phaeocryptopus gaeumannii). Currently, no solutions are in sight but aerially-applied sulfur may alleviate Swiss needle cast and its...

Towards a Conceptual Change Model to Support Organizational Change Efforts

Creator:: Hille, Joshua D.
Abstract:: Many projects fail because employees and managers have different understandings of project "success" or "value". Other projects fail because managers are unable to effectively align organizational values with those of their employees. This problem is widely understood, but there is little empirical research that specifies the nature and effect of...

A community-based approach for evaluating tradeoffs across marine ecosystem services in Oregon

Creator:: Freeman, Peter M.
Abstract:: As competing uses of our coastlines increase, natural resource agencies are employing marine spatial planning (MSP) to designate areas for different uses or activities in order to reduce conflicts while achieving ecological, economic and social objectives. A central challenge of implementing MSP is development of a rigorous approach for analyzing...

Abstract:: Several different petrological techniques have been applied to lava flows between 200 to 475,000 years old from Mount Hood, Oregon. Mount Hood is unusual, in comparison to nearby Mount St. Helens and Mount Jefferson, in that it has produced relatively homogeneous lava compositions over 475,000 years. Erupted lavas are mostly...

Abstract:: Standard accounts of women's relationship with technology stress women's need to overcome anxiety to achieve competence with computers. Recent studies provide evidence that this woman-anxiety-technology connection is an oversimplification of the relationship between women and computers. New literature also suggests that making computers more appealing will help girls overcome computational...
