An evaluation of understory vegetation dynamics, ecosystem resilience and state and transition ecological theory in an eastern Oregon ponderosa pine forest

Creator:: Carr, Craig A.
Abstract:: Relatively recent increases in ponderosa pine abundance have effected unprecedented changes to ecosystem structure and function. Efforts to restore ponderosa pine systems are often focused on the manipulation of tree structure and the re-introduction of a more natural fire regime. Successful restoration should also incorporate understory components but information addressing...

Comparison of high and low tannin sorghum grain with low quality roughage for feeding ruminants

Creator:: Wanyama, Justin Mukami
Abstract:: Two studies were conducted to compare lamb feedlot performance and digestibility of nutrients by lambs fed rations containing bird-resistant and bird-susceptible sorghum grain with 20 or 40% tall fescue hay as a source of roughage. Four rations were fed ad libitum on the performance study and at 80% of ad...

Production of SO₂ and SO₂ binding compounds by Saccharomyces cerevisiae during the alcoholic fermentation and the impact on wine lactic acid bacteria

Creator:: O'Neil, Allison L.
Abstract:: Malolactic fermentation (MLF) is important in the production of wines as it reduces acidity through the conversion of malic acid to lactic acid. However, successful MLF can be difficult to achieve due to yeast antagonism of the bacterium responsible for the secondary fermentation, Oenococcus oeni. In particular, yeast produced sulfur...

Radioxenon generation using highly enriched uranium

Creator:: Elliott, Anthony James
Abstract:: This work focuses on the generation and collection of four specific radioxenon isotopes; xenon-131m, xenon-133m, xenon-133 and xenon-135. These nuclides are created by fissioning a highly enriched uranium sample using a thermal neutron source from a university research reactor. The three main aspects of this work include: (1) Conducting preliminary...

Pseudoloma neurophilia in the Zebrafish (Danio rerio) : Consequences of Infection on Neurobehavioral and Biomedical Research using a Burgeoning Model Organism

Creator:: Spagnoli, Sean
Abstract:: Since its inception as a laboratory animal in the early 1970s, the zebrafish has proven itself a rising star in the world of comparative biomedical sciences due to its short generation time, ease of care, external fertilization, and transparent larvae. In a very few decades, the zebrafish has been utilized...

Effects of vegetation and disturbance on fungal communities in the western Cascades of Oregon

Creator:: Kageyama, Stacie Ann, 1967-
Abstract:: The use of high throughput molecular methods that allow for the study of bacterial communities in environmental samples is commonplace in microbial ecology. Until recently, fungal community ecology has focused on isolation, collection of sporocarps, or collection of ectomycorrhizal roots. The techniques used to extract and amplify DNA from environmental...

Lift Enhancement of Pliant Wings Through Bio-Mimicry

Creator:: Osterberg, Nathaniel Brent
Abstract:: Flexible aerodynamic surfaces have been shown to favorably influence flight characteristics at low Reynolds numbers by increasing lift, angle of attack at stall, and resistance to perturbation. The objective of the research presented within this thesis is to investigate the influence of two aspects of flight observed in biological flyers,...

Cosmovisions and Farming : An Investigation of Conventional and Alternative Farmers' Environmental Values along the Willamette River

Creator:: French, Melissa M.
Abstract:: Understanding which factors motivate farmers to adopt certain practices is an important part of helping to solve many agri-environmental issues. This study uses 19 interviews with farmers along Oregon’s Willamette River, a statewide producer survey, and select interviews with organizations and agencies active in the farming community to examine the...

The evolutionary stability of partial migration

Creator:: Ohms, Haley A.
Abstract:: Natural selection, in its most basic form, is described as a process in which traitsincrease or decrease in frequency depending on their fitness, and only the trait withthe highest fitness will remain in the population. Yet, populations rarely have asingle `optimal' trait. The way natural selection maintains this observed variationwithin...

Fuel Treatment Longevity in the Blue Mountains of Oregon

Creator:: Morici, Kat
Abstract:: Wildland fires are an increasingly extensive, expensive, and frequent occurrence in dry forests of the western United States. Fuel reduction treatments are designed to reduce extreme fire behavior, promote resilient forest structure, and facilitate fire control efforts. Although there is widespread recognition that repeated treatments are needed to maintain desired...
