Effects of Contemporary Forest Practices on Stream Nutrients, Temperature, and Periphyton in Small Headwater Streams

Creator:: Pimont, Cedric
Abstract:: Forest harvest practices can impact nutrient concentrations and stream temperatures, altering aquatic ecosystems. To better inform future sustainable forest resource management practices, quantifying the impact of current practices on water quality, particularly in headwater streams is important. In this study, I quantified monthly nitrate-nitrite (N) and orthophosphate (P) concentrations, 7-day...

Two Advances in Practical Alternative Energy: Thermotolerant Hydrogenase Concentration and Methane Hydrate Grain Size Proxies.

Creator:: Sullivan, Nichole D.
Abstract:: Methane hydrates and biohydrogen are two disparate subjects that are of interest in the growing field of alternative energy research. However, before commercial use becomes a viable option, each has challenges that need to be overcome. Methane hydrates require large investments of time and capital to locate. In this thesis,...

Bait and Trap Design Preferences for Drosophila suzukii

Creator:: Marcus, Monica H.
Abstract:: Knowledge of Drosophila suzukii's preference for an attractive trap design and bait can be used to improve detection and management of this new invasive fruit pest. Desired trap and bait attributes include: high D. suzukii capture and species specificity; early-season detection prior to significant crop damage; higher capture of females...

Influences of an Anti-inflammatory Drug, Ibuprofen, on Spatial Memory and NMDA Receptor Subunit Expression During Aging

Creator:: Márquez Loza, Alejandra
Abstract:: One of the first cognitive dysfunctions to arise with aging is memory loss, affecting an estimated 85% of elderly in the U.S. over the age of 80 with Age Associated Memory Impairment. A common feature in humans and animals experiencing memory loss with aging is the decline in N-methyl-D-aspartate (NMDA)...

Serum Haptoglobin as an Indicator for Calving Difficulties and Postpartal Diseases in Transition Dairy Cows

Creator:: Sabedra, Dominique A.
Abstract:: Abstract Haptoglobin is an acute phase protein that is elevated in response to tissue damage and infections in dairy cows. The objectives of this study were to evaluate whether serum haptoglobin concentrations in the first week after calving can indicate disease status and severity, and whether haptoglobin concentrations are elevated...

Guinea pig model of mild hyperandrogenemia – is it a suitable model for women with polycystic ovary syndrome (PCOS)? A pilot study

Creator:: Barboza Sagrero, Juriana E.
Abstract:: Polycystic Ovary Syndrome (PCOS) is an idiopathic disorder prevalent in ~5-10% of reproductive-aged women. In PCOS women who become pregnant, many experience complications including increased susceptibility of having a miscarriage, high blood pressure, and gestational diabetes, among others. Additionally, exposure to PCOS may have transgenerational impacts: offspring may be at...

Enzyme-Mediated Conversion of Glucolimnanthin to Bioherbicidal Breakdown Products

Creator:: Bratton, Daniel
Abstract:: The oilseed crop Limnanthes alba (white meadowfoam) is grown in Oregon. Methods were developed for the production of a liquid-based bioherbicide from meadowfoam seed meal (MSM). It was determined that glucosinolate-containing extracts of MSM can be combined with active-enzyme-containing liquid extracts of meadowfoam seed to form a fermented product rich...

Understanding polycyclic aromatic hydrocarbon (PAH) toxicity and inflammation in human bronchial epithelial cells

Creator:: Valdez, Teresa
Abstract:: There is increased emphasis on understanding cumulative risk from the combined effects of chemical and non-chemical stressors as it relates to public health. Recent animal studies have identified pulmonary inflammation as a possible modifier and risk factor for chemical toxicity in the lung after exposure to inhaled pollutants; however, little...

Unprecedented Retreat of Columbia Glacier Relative to the Last Millennium

Creator:: Kilmer, Zoe
Abstract:: Columbia Glacier, Alaska’s most rapidly retreating body of ice, provides a compelling insight into the fragile state of tidewater glaciers worldwide. Catastrophic retreat of the glacier’s terminal ice margin began in 1978 when contact was lost with its stabilizing terminal moraine shoal. Since this time, Columbia Glacier has lost ~20...

Native wildlife species (Pseudacris regilla) utilizing invasive-dominated habitat in a highly disturbed ecosystem

Creator:: Epperly, Haley K.
Abstract:: The Pacific Treefrog (Pseudacris regilla) is commonly encountered throughout the Pacific Northwest and can be an indicator for ecosystem health. At each life stage P. regilla utilizes a different habitat and therefore it is important to understand habitat use at all life stages to properly manage the ecosystem, however, few...
