Compensating effects and gene action estimates for the components of grain yield in winter wheat (Triticum aestivum, L. em Thell)

Creator:: Abi-Antoun, Michel
Abstract:: Five winter wheat cultivars and their diallel crosses were evaluated for plant height, harvest index, deading-maturity duration, the components of yield, (spikes per plant, spikelets per spike, kernel weight and kernels per spikelet)and total plant yield. Two diverse locations, Moro, a dryland site (250 mm annually) located in central Oregon...

Heritability for perloline, nitrogen, and digestibility characteristics in tall fescue (Festuca arundinacea, Schreb.) single-crosses grown in two locations

Creator:: Watson, Clarence Ellis
Abstract:: Tall fescue often results in poor liveweight gains. This may be accounted for by variations in perloline content, nitrogen content, or digestibility of the plant. Two groups of tall fescue plants were examined for each of these traits. These groups consisted of (a) fifteen single-crosses of a six parent diallel...

Pathogenicity of experimentally induced concurrent infections of Fasciola hepatica and Haemonchus contortus in sheep

Creator:: Presidente, Paul J.
Abstract:: Twenty yearling sheep were allotted to four groups, each containing five sheep of approximately equal weight. On experimental days 0, 1, 2, 3, and 4, each sheep in each group was given the following inoculations by stomach tube: five sheep in group I (Fasciola hepatica-exposed controls) were given approximately 120...

Geochemical cycling in a Pacific Northwest estuary (Tillamook Bay, Oregon, USA)

Creator:: Colbert, Debbie L.
Abstract:: This thesis investigates the behavior of major inorganic nutrients (P, N, Si), trace metals (Mn, Fe), and alkaline-earth metals (Ba) within Tillamook Bay over seasonal cycles and under a range of river discharge conditions from October 1997 through December 1999. Located in the Pacific Northwest region, Tillamook Bay is an...

An Oregonian Jarabe : Danza Folklórica and Mexicana Mothers

Creator:: Olvera, Monica L.
Abstract:: Acculturative stress can be associated with increased conflicts between Latino parents and adolescent youth, and have negative effects on Latino immigrant parents' psychosocial functioning and parenting practices. Yet, the potentially deleterious effects of acculturative stress on Latino immigrant parents' psychosocial functioning and parenting practices may be mitigated through positive acculturative...

In Utero Exposure to Arsenic and Mercury : Epigenome-Wide Associations and Newborn Health Outcomes

Creator:: Cardenas, Andres
Abstract:: Mercury and arsenic are known developmental toxicants and environmental exposures are ubiquitous worldwide from natural and anthropogenic sources. Prenatal exposure to both contaminants are independently associated with adverse perinatal health outcomes and latent disease risk that could be in part mediated by epigenetic reprogramming events. Fetal programming events involving DNA...

Spatio-Temporal Analysis and Modeling in the Marine Environment : Humpback Whale Genetic Variability and Seabird Distributions in the Northeastern Pacific Ocean

Creator:: Dick, Dorothy Marie
Abstract:: The rapid decline of marine ecosystems worldwide and the failure of traditional single species management pushed for the development of ecosystem-based conservation measures such as marine protected areas (MPA) to slow the loss of marine biodiversity. One approach to MPA creation advocates targeting marine megafauna (e.g., marine mammals, seabirds, sharks,...

The effects of multiple pathogens on amphibians in the Pacific Northwest

Creator:: Romansic, John M.
Abstract:: The earth is undergoing a “biodiversity crisis” characterized by loss of populations, species, genetic diversity, and ecosystem services. Part of this crisis consists of population declines, extinctions, and increased incidence of deformities in amphibians. It is unknown whether deformities contribute to these declines. Many cases of population declines in amphibians...

Biomarkers of oxidative stress and DNA damage in agricultural workers

Creator:: Muniz, Juan Fermin
Abstract:: Pesticides are among the most pervasive environmental contaminants and they are an important potential risk for human health. Agricultural workers are constantly exposed to pesticide spray, drift and residues in the soil and foliage. Many agricultural pesticides are readily absorbed by the body, through contact with the skin, the respiratory...

Genotype-environment interaction in winter wheat F₁ progeny

Creator:: Peterson, C. J.
Abstract:: Seven winter wheats were evaluated for plant height, the components of yield and yield in a diallel cross at Pendleton, Oregon and Lind, Washington. An additional parent was added to the diallel cross at Pullman, Washington. Two levels of nitrogen and five replications were utilized at each of the locations....
