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,...

A whale's tale of mtDNA diversity and differentiation : the Antarctic blue whale

Creator:: Sremba, Angela L.
Abstract:: Twentieth century commercial whaling drastically reduced the abundance of great whale populations in the Southern Ocean. Exploitation began on the south Atlantic island of South Georgia, where catch records account for over 175,000 whales killed. Modern whaling within the Southern Ocean depleted populations rapidly, and by 1966, hunting blue whales...

Agricultural impacts on amphibian survival, growth, and distributions

Creator:: Baker, Nick J.
Abstract:: The potential impact of chemical contaminants and conservation practices on amphibians in agricultural landscapes is a key research topic globally. Amphibians represent a common group in many freshwater systems and are currently experiencing worldwide population declines. Global amphibian declines may be attributed to a number of causes, including habitat loss,...

Population Differentiation in two Northeastern Pacific Marine Species

Creator:: Curran, Lorne Sullivan
Abstract:: Population genetic techniques are now preeminent in differentiating wild populations. Natural resource managers rely on them in their efforts to restore viable populations of fish and wildlife. Overfishing adversely impacted Yelloweye Rockfish (Sebastes ruberrimus) on the U.S. West Coast in the late 20th century. Management actions included shutting down the...

Parental beliefs and practices : influences of parenting in Latino/a and Caucasian children's behavioral regulation

Creator:: Diaz, Guadalupe
Abstract:: The transition to kindergarten can be challenging for many children who do not have the necessary skills to meet the demands of classroom settings such as paying attention, remembering instructions, and demonstrating self-control. Children who lack the necessary behavioral regulation skills to meet the demands in the classroom environment are...

Calcium Ion Transport via Seeping Flow Events through Epikarst Microfissures

Creator:: Windom, Lisa M.
Abstract:: Solute transport models in karst groundwater must consider variable and complex flow regimes. Within fissures less than 2 mm in aperture, during unsaturated flow events, seeping flow may flow as films or under capillary tension as a capillary rivulet. This project focuses on exploring the mass transport characteristics of seeping...

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...

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...

Spatial changes in alpine treeline vegetation patterns along hiking trails in Glacier National Park, Montana

Creator:: Klasner, Frederick L.
Abstract:: Sequential aerial photography was used to identify effects of hiking trails on the spatial distribution of subalpine fir (Abies lasiocarpa) habitat at alpine treeline. Vegetation change over a 46 year period was compared along trails relative to areas without trails, at five study sites in the McDonald Creek drainage of...
