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,...

Flood history and sedimentation at the mouth of Redwood Creek, Humboldt County, California

Creator:: Ricks, Cynthia L.
Abstract:: Since the early 1950's, the distribution of sediment at the mouth of Redwood Creek has been altered by the effects of channel aggradation and channelization along the lower reach. Severe flooding in 1953, 1955, and 1964 caused bank erosion, landsliding, and channel geometry changes along Redwood Creek. The increased sediment...

Sources of weld strength variability in capacitor discharge welding

Creator:: Benjarattananon, Jukchai
Abstract:: Capacitor discharge welding (CDW) is a rapid solidification joining process under the influence of one-dimensional thermal gradients. Although CDW is useful for joining small parts and dissimilar metals, CD welded joints have a large variability in weld strength. CDW is not widely accepted because of a lack of automated process...

Stand development after 20-years of growth in Douglas-fir and red alder mixtures

Creator:: Garrelts, Brennan T.
Abstract:: This study examines the long-term role of interference on stand development of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) and red alder (Alnus rubra Bong.) planted mixtures in the Central Cascades of Oregon, USA. The two species are common associates in naturally regenerated and planted conifer stands in the Pacific Northwest. Due...

Characterizing the response of coralline algae to ocean acidification and nutrient changes in the California Current system

Creator:: Letzing, Sandy
Abstract:: Ocean acidification (OA) has emerged as an important focus of research and policy in this decade. Ocean acidification specifically refers to changes in the inorganic carbon system in the ocean resulting from its absorption of human-released CO₂ from the atmosphere. Anthropogenic atmospheric CO₂ levels are rapidly increasing; much of this...

The transfer process of Latina/o students from community college to the university : what are their experiences?

Creator:: Cortez, Edén
Abstract:: This qualitative study explores the experiences of Latina/o transfer students from a two-year to a four-year institution. Six Latina/o transfer student from the Pacific Northwest participated in one-on-one semi-structured interviews. The researcher utilized Critical Race Theory, LatCrit, Validation Theory, and Chicana Feminist Epistemology to bring forth the narratives of the...

Western larch resistance to Douglas-fir beetle attack

Creator:: Neal, Tiffany A.
Abstract:: Live western larch, Larix occidentalis Nutt., a tree species resistant to the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, produces the monoterpene 3-carene in higher concentrations compared to Douglas-fir, the preferred host of D. pseudotsugae (Reed et al. 1986). The inhibitory effects on attraction to aggregation pheromones and toxicity of 3-carene to...

Transpiration and the atmospheric boundary layer : progress in modeling feedback mechanisms

Creator:: Heinsch, Faith Ann
Abstract:: Simple models of transpiration, e.g., the Penman-Monteith equation, treat atmospheric conditions as driving variables. In fact, transpiration modifies temperature and humidity throughout the convective boundary layer, creating feedbacks that stabilize the water use of vegetation. This thesis concentrates on the new empirical relationships proposed by Monteith (1995), for developing simple...

Overland flow and sediment production potentials in logged and nonlogged sites of a ponderosa pine forest in northeastern Oregon

Creator:: Williams, John Dana
Abstract:: The purpose of this research was to determine if overland flow and sediment production were different in logged (on snow, frozen soil, and prescribed skid trails) and nonlogged sites in a Pinus ponderosa Laws.! Symohoricaroos albus Laws. community in the foothills of the Wallowa Mountains in northeastern Oregon. To determine...
