Perspectives on a Community Forest : A Practice in Nature Writing

Creator:: Hadella, Lucia C.
Abstract:: The McDonald Forest is one of the Oregon State University Research Forests, owned by the College of Forestry and located approximately seven miles northwest of the heart of Corvallis. I took four hikes on the McDonald Forest at four major recreation destinations: Oak Creek, Dimple Hill, Lewisburg Saddle, and Peavy...

Physical factors affecting the spatial distribution of infaunal bivalve assemblages and species along the continental shelf of the Pacific Northwest

Creator:: Labou, Stephanie Grace
Abstract:: The spatial distribution and abundance patterns of benthic infauna result from interactions with a host of environmental variables including sediment characteristics (percent silt-clay, grain size, total organic carbon), depth, temperature, and dissolved oxygen. This thesis focuses on the association of bivalve assemblages and species with potentially influential environmental variables along...

Survival Mediated Capture and Fusion Cross Sections for Heavy Element Synthesis

Creator:: Yao, Liangyu
Abstract:: The synthesis of superheavy element evaporation residues is described by the product of the capture cross section, fusion probability, and survival probability. Capture cross sections are moderately well known. The fusion probability is the least known with many uncertainties. The formalism for the survival probability is known, but the parameters...

Grape Powdery Mildew Management: The Interaction Between Inflorescence Stage and Fungicide Chemistry

Creator:: Warneke, Brent W.
Abstract:: Grape powdery mildew (GPM, causal agent Erysiphe necator) is the most economically important disease of grapevine in the Western U.S. Low levels of GPM infection on clusters (1-5%) can negatively affect wine sensory quality, so intensive fungicide programs are common. This may lead to problems like excessive fungicide use and...

Is Resistance Futile: Examining Fitness Costs Associated with QoI Resistance in E. necator

Creator:: Newbold, Chelsea L.
Abstract:: Quinone outside Inhibitor (QOI) fungicides are one of the most widely used fungicide classes (FRAC 11) in the world. This popularity is the result of their ability to effectively manage a wide array of economically important pathogen species on a broad range of crops. While having mostly preventative activity, some...

New Tools for Managing Erysiphe necator: Rapid Sampling Approaches and an Exploration of Grower Opinions and Perspectives towards Collective Action and Information Transfer

Creator:: Lowder, Sarah R.
Abstract:: The scale of pest and disease dispersal is often larger than the scale of individual farms. Therefore, an individual grower’s response to pests and diseases can affect and is affected by their surrounding growing region. Individual growers are also not isolated, and engage in various forms of information gathering, sharing,...

Overwintering of Erysiphe necator and Inoculum Monitoring for Decision Aids

Creator:: Thiessen, Lindsey D.
Abstract:: Grape powdery mildew (Erysiphe necator) causes economic damages to grape worldwide due to the cost of management and injury to berries. Each region where European grapevine (Vitis vinifera) is grown experiences a unique epidemic, and disease prediction models that are based on empirical correlations of weather data to disease fail...

Using Spatial Capture-Recapture to Estimate Density of Roosevelt Elk in Western Oregon

Creator:: Nelson, Jennifer E.
Abstract:: Spatial capture-recapture (SCR) is employed for estimating abundance and density of species, particularly those that are cryptic or solitary, and evaluating how population density varies with habitat. However, it is uncertain whether estimates are biased when applied to species that aggregate, such as elk (Cervus canadensis). Wildlife managers in the...

Risky business : evaluating the vulnerability and impacts from simulated oil spills in the Gulf of Mexico

Creator:: Nelson, Jake R.
Abstract:: Exploration and production of oil in the Gulf of Mexico has seen an astonishing increase since the first well was drilled in 1936. Much of the current exploration is occurring in waters greater than 5000 feet. The largest and most unprecedented oil spill in the United States occurred on April...

The Influence of Administrative Supervision on Counselor Subordinates: Uncharted Territory

Creator:: Nelson, Marci L.
Abstract:: The purpose of this dissertation is to convey research on counselors’ experience of administrative supervision. While research in counseling has given much attention to clinical supervision and the relationship between clinical supervisor and supervisee, it has not adequately attended to the important and influential role of administrative supervision and its...
