Life History Trade-offs: The Effects of Habitat Selection on Columbian Black-tailed Deer Survival in Oregon

Creator:: Clark, Jessica S.
Abstract:: The assessment of habitat quality for wild populations requires evaluation of vital rates associated with the use of that habitat. Factors associated with bottom-up (forage) or top-down (predation) regulation and the relative contribution of these processes on ungulate populations are difficult to quantify, especially for a cryptic, but widely distributed...

Comparing vegetation and soils of remnant and restored prairie wetlands in the northern Willamette Valley

Creator:: Taylor, Sara M.
Abstract:: Native prairies of the Willamette Valley are considered among the rarest of Oregon's ecosystems (Clark and Wilson, 2001). As a result of agriculture conversion, urban development and cessation of native burning, Willamette Valley prairies have become highly fragmented and invaded by non-native species, leaving little room for native plant diversity....

Identification of Bitter Peptides in Aged Cheddar Cheese

Creator:: Kuhfeld, Russell
Abstract:: Bitterness is a common flavor attribute of aged cheese, but excessive levels are a flaw leading to consumer rejection. Bitterness in cheese has been primarily associated with milk casein-derived peptides of medium size (500–3,000 Da) and relative hydrophobicity. Herein, we demonstrate a novel approach for the identification of bitter peptides...

Heats of immersion and swelling of quaternary ammonium complexes of montmorillonites

Creator:: St. Clair, Akos Dominic
Abstract:: Heats of immersion were obtained for four different organophilic clay complexes in a series of normal alcohol-heptane mixtures with alcohols of increasing chain length. The immersion calorimeter employed was the Dewar type with a sensitivity of approximately 5 x 10⁻⁵°C. Gel volumes were determined for two of the clay complexes...

Solvent selectivity by an organoclay complex

Creator:: Hanson, Dean Burton
Abstract:: The selective adsorption from a series of binary solutions on an organoclay complex has been studied in relation to the gelling ability of this organoclay. Adsorption isotherms were obtained for a series of polar organic solvents in toluene. The isotherms were of the usual "S" or "U" type depending upon...

The effects of site preparation on native forb establishment in a wet prairie, Willamette Valley, Oregon

Creator:: Norman, Katherine N.
Abstract:: Wetlands and wet prairies are economically and environmentally valuable ecosystems, but many have been degraded or converted to other uses. As human understanding of wetlands' value has increased, restoration efforts have grown correspondingly. Restoration attempts use a diversity of methods, which often include seeding with native plant species. This thesis...

A Comprehensive Evaluation of the Nonvolatile Chemistry Affecting the Sensory Bitterness Intensity of Highly Hopped Beers

Creator:: Hahn, Christina
Abstract:: The range of different nonvolatile constituents extracted from hops in highly hopped beers suggests that iso-alpha acids may not be the sole contributor to beers’ bitterness. Among brewers producing hop-forward beer styles there is a growing concern that the Bitterness Unit (BU) is no longer an accurate predictor of beer...

Climate warming effects on the life cycle of the parasite Ceratomyxa shasta in salmon of the Pacific Northwest

Creator:: Chiaramonte, Luciano V.
Abstract:: Aquatic ecosystems continue to be increasingly affected by climate warming. For salmonids in the Pacific Northwest of North America, increasing temperatures pose tighter thermal constraints on their habitat use as well as aspects of their individual performance, such as disease resistance. This thesis examines the effect of temperature on the...
