Invasion of Brachypodium sylvaticum in prairie and forest habitats : differences in community structure between uninvaded and invaded systems in Bald Hill Park, Corvallis, Oregon

Creator:: Goodell, Whitney
Abstract:: Brachypodium sylvaticum (Huds.) Beauv. is an invasive grass that can be found in forest and prairie communities throughout the Willamette Valley, Oregon. It can out-compete native species of grasses and forbs and become dominant in a broad range of habitats. This study investigated if there were differences in vegetation structure...

Using Cattle as a Tool : Restoring the Sumpter Valley Dredge Tailings

Creator:: Defrees, Dallas K.
Abstract:: A period of over forty years (1913-1954) of gold dredging dramatically changed the landscape of Sumpter Valley, Oregon into a rocky, uninhabitable terrain. The Defrees Ranch LLC used cattle feeding to increase top soil, vegetation, and habitat on the dredge tailings. This thesis investigated the use of feeding cattle as...

Physiological effects of forb and legume pastures on lactating dairy cows as indicated by blood parameters

Creator:: Marr, Kaylee M.
Abstract:: Use of secondary metabolites in legumes and herbs as forage for dairy cattle is tested through analysis of blood parameters including beta-hydroxybutyrate (BHBA), cholesterol, urea, creatinine, haptoglobin, bilirubin, thiol groups and advanced oxidation protein products (AOPP). The pasture treatments were grass-based (‘Perun’ festulolium (X Festulolium braunii), ‘Rustler’ tall fescue (Festuca...

Diet overlap by DNA metabarcoding of mule deer, elk, and cattle in ponderosa pine forest of eastern Oregon

Creator:: Faber, M. Kate
Abstract:: Millions of acres of rangeland in the western U.S. is shared habitat by elk (Cervus canadensis), mule deer (Odocoileus hemionus), and cattle (Bos taurus). Potential competition between these ungulates for the same forage species can be understood from their diet composition. I used DNA metabarcoding methods with trnL primers to...

A Proposed Equine Business Model for the Training and Resale of Jumpers

Creator:: McCarthy, Liz
Abstract:: The goal of this project was to determine whether an equine business in which the sole income is from the short term retraining and resale of horses could be successful. Horses would hypothetically be kept for not less than six months and not longer than one year, and priced from...

Pollen fidelity of Apis mellifera L. during pollination of Limnanthes alba Hartw. ex Benth. ssp. alba, Limnanthaceae

Creator:: Watkins, Ann J.
Abstract:: Limnanthes alba, commonly known as meadowfoam is a popular commercial crop because its seed oil is composed of long carbon chains that provide it with high oxidative stability and consequently make it a desirable ingredient in cosmetic products. As a commercial pollinator, the western honey bee, Apis mellifera, may be...

Facility Planning for Large Equine Facilities in the Pacific Northwest

Creator:: Glenn, Aimee K.
Abstract:: Large equine facilities are comprised of many different departments (areas) that are necessary for the proper care and maintenance of horses. The placement of departments is often inefficient due to the slow growth of equine facilities. As a result, facility layout becomes a crucial aspect requiring explicit consideration because mandatory...

Wildfire Severity Has a Minimal Influence on Pollen Diversity Used by Developing Mason Bees (Osmia lignaria) in Mixed Conifer Forest

Creator:: Bell, Nicole C. S.
Abstract:: Native bees are critically important organisms that support biodiversity and crop production via their pollination services. Wildfires in temperate conifer forests can increase bee abundance and flowering plant density due to increased light exposure, but little information is available regarding how wildfire severity influences provisioning to bee offspring, which is...

Evaluation of Current Dairy Heifer Growth Models

Creator:: Zaworski, Erica M.
Abstract:: Growth models developed by Pennsylvania State University (Penn State) extension services for Holstein and Jersey heifer height and weight were evaluated using OSU dairy herd heifer data. The purpose of this study was to determine the ability of the models to predict heights and weights of heifers in the OSU...

Effects of nesting waterbirds on nutrient levels in mangroves, Gulf de Fonseca, Honduras

Creator:: McFadden, Tyler Neal
Abstract:: Mangroves provide numerous ecosystem services, including biodiversity values such as nesting sites for piscivorous waterbirds. High concentrations of pisicivoirous birds are hypothesized to affect ecosystem dynamics, yet few studies have examined their effects in mangroves. We examined the effects of nutrient enrichment by colonial waterbirds at a mangrove rookery in...
