Investigation of hop downy mildew through association mapping and observations of the oospore

Creator:: Parker, Thomas B.
Abstract:: Hop downy mildew is a devastating disease affecting hop requiring expensive fungicide applications throughout the growing season. Plant resistance is highly desirable and theorized as being decidedly quantitative with dominance and epistasis involved in resistance. An association mapping approach using a mixed-model was used to identify AFLP markers associated with...

A macroscopic to microscopic study of the effects of barotrauma and the potential for long-term survival in Pacific rockfish

Creator:: Pribyl, Alena L.
Abstract:: Depleted species of rockfish (Sebastes spp.) from the Northeast Pacific experience high discard mortality due to "barotrauma," induced from the rapid change in pressure during capture. Research suggests rockfish have the potential to survive barotrauma if immediately recompressed, but the potential for long-term recovery is unknown. In this project, we...

Hydrophobicity, Anion Exchange, and Phytoaccumulation of Per- and Polyfluoroalkyl Substances (PFAS): Retention and Remediation

Creator:: Parker, Bethany A.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are a group of contaminants of great concern due to their toxicity and ubiquity in the environment. Remediation efforts historically have focused on granular activated carbon (GAC) because of its low maintenance and relatively low cost. However, GAC is not PFAS selective and is especially...

UVB Radiation Affects the Quality of the Female Sexual Attractiveness Pheromone of the Red-Sided Garter Snake

Creator:: Vigeland, Anna E.
Abstract:: In this study, pheromone and skin lipid samples collected from red-sided garter snakes (Thamnophis sirtalis parietalis) were exposed directly to either full-spectrum light or full-spectrum plus UVB light. In addition, female and male snakes were exposed to daily doses of either full-spectrum or full-spectrum and UVB light, after which the...

Sexual dimorphism and seasonal changes in the Harderian gland of the red-sided garter snake, Thamnophis sirtalis parietalis

Creator:: Erickson, Sten M.
Abstract:: The Harderian gland (HG) of the red-sided garter snake, Thamnophis sirtalis parietalis, is a secretory structure that plays a role in the vomeronasal system by solubilizing semiochemicals such as prey chemoattractants and the female sexual attractiveness pheromone. The HG produces secretions containing pheromone-binding proteins that form a complex with pheromone...

Fish and invertebrate distribution at multiple scales in Thomas Creek, Oregon : a transition from conifer uplands to agricultural lowlands

Creator:: Langshaw, Russell B.
Abstract:: Longitudinal patterns of fish and benthic invertebrate distribution and habitat use were similar in Thomas Creek, Oregon but clarity of these patterns differed. I studied fish and aquatic invertebrates simultaneously, at multiple scales, and used multivariate statistical techniques to compare responses to the same environmental conditions. Both types of organisms...

Knot theory : in imitation of Lewis Thomas

Creator:: Schmidgall, Matthew J.
Abstract:: Knot Theory: In Imitation of Lewis Thomas is a collection of 14, 1200-word essays written in the style of Lewis Thomas, a physician who regularly contributed to The New England Journal of Medicine. His 1200-word column, "Notes of a Biology Watcher," ran from 1971 - 1980. The resulting compilations collectively...

Shift dynamics for cyclically presented groups with length four positive relators

Creator:: Parker, Forrest W.
Abstract:: In 2014, W. Bogley identified a relation between the algebraic and geometric prop- erties of cyclically presented groups Gn (w) in the case where w = x0xkxl is a positive word of length three. Specifically, it was shown that the dynamics of the shift θG on the group G =...

An investigation of the relationship between Christian religious ideology and identity achievement in selected university students

Creator:: Parker, Carl Edward
Abstract:: The purpose of this study was to determine whether there is a relationship between identity achievement and Christian religious ideology in selected university students attending Oregon State University. The sample consisted of two hundred and forty-nine students enrolled during the winter quarter 1978 in Psychology and Education courses. The respondents...

Soil compaction in central Oregon volcanic ash soils and the subsequent effects on residual ponderosa pine growth

Creator:: Parker, Robert T.
Abstract:: Although previous research in central Oregon has shown soil compaction can lead to a decline in site productivity, the subject is not understood well enough to predict the growth changes resulting from a given level of soil compaction. A study was initiated to relate the basal area, height and volume...
