Improving Best Management Practices for Potato Production in the Columbia Basin : An Evaluation of Essential Oils for Control of Verticillium Wilt and the Fate of Chloride in the System

Creator:: Light, Sarah Elizabeth
Abstract:: Although the potato (Solanum tuberosum L.) is a global crop, few growing regions rival the high yields of the Columbia Basin of Eastern Oregon and Washington. Two research projects were conducted in Hermiston, OR to contribute to best management practices for the region. The first project evaluated the efficacy of...

Selenium metabolism in the chick and effects of Vitamin E and selenium on heat stress

Creator:: Alayan, Mohammad Atta
Abstract:: An in vitro study was conducted to investigate the metabolism and distribution of Se⁷⁵-selenite and Se⁷⁵-selenomethionine (SEM) in chick blood. Se⁷⁵-selenite is taken up by RBC (13% within 20 minutes) and expelled into the plasma to become bound to proteins. In contrast, Se⁷⁵-SEM showed a more gradual and continuous buildup...

The Effects of Phytoplankton Prey Species and Nutrient Limitation on Microzooplankton

Creator:: McBeain, Kelsey Ann
Abstract:: Phytoplankton and microzooplankton comprise the base and the first link of the marine food web, respectively. These microbes are key drivers of marine carbon and nutrient cycles. Phytoplankton convert atmospheric CO₂ into organic carbon, and microzooplankton consume phytoplankton, packaging phytoplankton carbon into particulate forms that have a variety of fates:...

Effects of Stage 0 treatment on spring Chinook juveniles within South Fork McKenzie River in Oregon

Creator:: Hahn, Aleah
Abstract:: Low-tech habitat restoration techniques, including Stage 0 treatments, are increasingly applied but often lack robust evaluation of their effects. In 2018, one kilometer of the South Fork McKenzie (SFMK) River, OR was modified to the Stage 0 condition for the benefit of ESA-listed Chinook by raising the incised channel to...

Fish sauce : the alternative solution for Pacific whiting and its by-products

Creator:: Lopetcharat, Kannapon
Abstract:: Pacific whiting and its by-products were good raw materials for high quality fish sauce production. Heat stable and salt activated enzymes were responsible for autolytic activity in Pacific whiting and by-products. According to temperature profiles of raw materials at various salt concentrations, two fermentation temperatures, 35°C and 50°C, were selected...

Molecular relationships among multiple-sized plasmids of Pseudomonas syringae pv. phaseolicola

Creator:: Quant, Rebecca L.
Abstract:: Five strains of the bean pathogen Pseudomonas syringae pv. phaseolicola were analyzed for plasmid number, size, and relatedness. Each strain contained one or two indigenous plasmids which ranged in size from 6.8 to 151 kbp. BamHI and EcoRI restriction patterns revealed that total plasmid DNA from each strain had a...

An Evaluation of the Effects of the Parasite Salmincola californiensis on At-Risk Chinook Salmon Populations

Creator:: Gardner, Ethan N.
Abstract:: Once abundant in their native range, Pacific salmon species (Oncorhynchus spp.) were widely distributed across the northern Pacific Rim from South Korea and Japan to the Sacramento River in California. Remaining populations are subject to population-level threats, including pathogens. The freshwater parasitic copepod Salmincola californiensis is associated with the reduced...

Effects of dietary selenium ad vitamin E on he gray-tailed vole

Creator:: Pond, Finn Richard
Abstract:: The gray-tailed vole (Microtus canicaudus) demonstrated a requirement for selenium and vitamin E. Animals deficient in both nutrients suffered from liver necrosis and an unthrifty condition characterized by inappetence, profuse diarrhea, and swollen eyes. Vitamin E appeared less effective than selenium as a prophylaxis against this syndrome. Total body weights,...
