Flow-Solute : A Tool for Exploring the Effects of Nitrogen Management in Alternative Future Scenarios

Creator:: Wentworth, Andrew Michael
Abstract:: Surface water quality is a growing concern in the Willamette River Basin and elsewhere. The region's growing population is dependent on the availability of clean water for drinking water, irrigation, wastewater dilution, and wildlife habitat. Watershed management to produce economic goods and environmental services requires an understanding of basic hydrologic...

Addressing Emerging Issues in Tropical Ecohydrology : A Combined Hydrometric and Isotopic Approach to Evaluate the Origin and Age of Water in a High-Elevation Tropical Ecosystem

Creator:: Mosquera, Giovanny M.
Abstract:: This thesis focuses on the identification of ecohydrological processes in nested system of catchments in a tropical alpine (the wet Andean páramo) ecosystem. We accomplish this by conducting a water stable isotopic characterization of water sources, an evaluation of the mean transit time (MTT) of streams waters, and the investigation...

The effects of copper supplementation and breed on milk fatty acid profile

Creator:: Sumner, Jennifer M.
Abstract:: An experiment was conducted to determine the effect of dietary copper (Cu) on Cu status and lipid metabolism in Holstein and Jersey cattle. Eight Jersey and8 Holstein cows in mid-lactation were blocked by days in milk (169 ± 37) and assigned at random to one of two diets. Cows received...

Assessing the phosphorus and potassium balances in Oregon's dairies

Creator:: Higgs, Kathryn N.
Abstract:: A field study was conducted to assess phosphorus (P) and potassium (K) concentrations of both lactating and dry cow diets on Oregon's dairies. Thirty-seven dairy farms, located in western Oregon, were grouped according to geographic region, valley (V) or coast (C), and herd size, small (S) or large (L). Farms...

The effect of nicotinic acid supplementation during late-gestation on lipolysis and feed intake during the transition period

Creator:: Chamberlain, Jason L.
Abstract:: An experiment was conducted with 27 multiparous Holstein and 27 multiparous Jersey cows to determine if nicotinic acid (NA) supplementation during the prepartum phase of the transition period decreases lipolysis and improves dry matter intake and to determine if Holstein and Jersey cows respond similarly to NA supplementation. Cows were...

Routes to Certification and Turnover Intentions of Early Career Wisconsin Agriculture Teachers

Creator:: Claflin, Kellie
Abstract:: The purpose of this study was to discover the routes to certification and turnover intentions of Wisconsin agriculture teachers with fewer than three years of experience teaching agriculture. The study also evaluated the relationship between the routes to certification and turnover intentions. A census of all Wisconsin agriculture teachers with...

Fire Refugia Function and Composition in Dry Mixed-Conifer Forests of Oregon’s Blue Mountains

Creator:: Downing, William M.
Abstract:: Contemporary fire effects are raising concerns about the resistance and resilience of dry mixed-conifer forests to large wildfires. Fire refugia – unburned or low-severity patches within fire perimeters – are understudied components of post-fire mosaics that may be key drivers of forest recovery following high-severity fire. Little is known about...

The effects of exogenous melatonin on the plasma levels of interstitial cell stimulating hormone in sheep

Creator:: French, Larry Robert
Abstract:: There is an increasing body of evidence that the pineal gland acts as a neuroendocrine transducer, translating neural information about environmental lighting condition into hormonal information. In the rat, light controls the production of melatonin which acts via the hypothalamic-hypophyseal pathway to control the function of the gonads, A similar...

Fatigue patterns of flexor and extensor muscle groups about weight-bearing and nonweight-bearing joints of humans

Creator:: French, Stephen Neil
Abstract:: Forty-eight young adult males were ranked on the basis of mean hand-grip strength scores and the middle one-third, the medium strength range, were chosen as subjects. These sixteen subjects were given 30 serial trials in each of four tests; knee flexion, knee extension, elbow flexion, and elbow extension. Each trial...

Photo-identification of Melon-headed Whales (Peponocephala electra) in the Marquesas Islands : Creation of the First Photo-identification Catalog and Estimation of Group Size and Minimum Abundance in a Remote Archipelago

Creator:: McClung, John Ralph, II
Abstract:: For many species of oceanic dolphins, photo-identification and genetic data indicate that these island-associated populations are demographically isolated from pelagic populations and that island-associated populations exhibit very different patterns of movement and habitat use. Melon-headed whales (Peponocephala electra) are generally considered a pelagic dolphin, but have been documented around oceanic...
