Influence of flower native status, color, and morphology on visiting preferences of bees in riparian areas of eastern Oregon

Creator:: Roof, Samantha M.
Abstract:: Effectively restoring or conserving bee habitat requires a better understanding of the complex relationship between bees and flowering plants, but information about bee preferences is currently lacking. The purpose of this study was to examine bee-plant associations in a riparian area of Starkey Experimental Forest and Range (Starkey) in eastern...

Production and invasion of butterfly bush (Buddleja davidii) in Oregon

Creator:: Ream, Julie
Abstract:: Butterfly bush (Buddleja davidii), an ornamental native to China, is an invasive species in Oregon and many other areas. In Oregon, butterfly bush invades disturbed areas, particularly riparian areas. The Oregon nursery industry has the highest farm-gate value of all agricultural commodities and butterfly bush is a significant plant to...

Quantifying the Potential of Native Plants for Improving Pollination and Biological Control in Agroecosystems

Creator:: Winfield, Tammy L.
Abstract:: Agricultural areas can be inhospitable to the attraction and maintenance of beneficial insects like natural enemies and pollinators and this can result in a decrease in the ecosystem services of pollination and pest control that these insects supply. If habitat can be created and maintained on-farm, an increase in the...

Fungal endophytes as source to combat bacterial infections

Creator:: Green, Jaimie R
Abstract:: Endophytes, foliage inhabiting fungi, are an unexplored source of fungal biodiversity and a potential resource for the production of bioactive natural products. In this research, leaf tissues from the species Arbutus menziesii, Rhododendron macrophyllum and the genus, Ilex and Salix were collected for the isolation of endophytic fungi. Fungal extracts...

Antibiotic Resistance Gene Transfer in Oysters as a Result of Fecal Pollution

Creator:: Cooper, Rebecca
Abstract:: Antibiotic resistance is an increasing problem in many species of bacteria today, with pathogens an important focus. Fecal contamination of shellfish is already a concern due to potential pathogens. This report examines the possibility of resistance gene transfer between microbes, due to fecal bacteria, within the oyster. In this study,...

Incorporation of aerodynamic and boundary layer resistances in determining initial evaporation rates of pesticides from turf grass

Creator:: Conway, Michael
Abstract:: Evaporative loss rates of pesticides, following application to turfgrass, were measured using the Backward-Time Lagrangian stochastic Dispersion model (Flesch, Wilson, Journal of Applied Meteorology, 34, pp. 1320-1332. All pesticides were applied to a 22.8 m x 22.8 m orchard ryegrass turf plot near Corvallis, Oregon. Solar radiation, ambient temperature, surface...

Exploring Pactamycin Biosynthesis

Creator:: Roland, Jessica
Abstract:: Pactamycin, produced by the soil bacterium Streptomyces pactum, is a cytotoxic antibiotic that belongs to the aminocyclitol family of natural products. This antibiotic has shown various forms of biological activity, including antibacterial, antifungal, antimalarial, and antitumor activities. Despite its outstanding biological activity, the mode of formation of its pharmacophore (the...

Soil Fire Ecology: Assessing Wildfire Severity Impacts on Pacific Northwest Forest Soil Carbon

Creator:: Fleetwood, Shea
Abstract:: Pacific Northwest temperate rainforests are anticipated to experience increasingly frequent and severe wildfires in the foreseeable future due to climate change, increased fuel loads, and deforestation. Soil, underlying these forests, is the largest terrestrial carbon (“C”) reservoir. Fire disturbance influences soil C persistence, the timeframe and magnitude of which remain...

Native bees, honeybees and pollination in Oregon cranberries

Creator:: McKenney, Melissa A.
Abstract:: Farmers rely almost exclusively on the imported European honeybee (Apis mellifera L.) for fruit and vegetable crop pollination services. The recent decline in honeybee health has underscored he danger of relying on a single species to provide vital services. Increasing pollinator biodiversity with native bees may provide biological insurance against...

Anti-Mullerian Hormone (AMH) Levels Are Reduced by Age, But Do Not Correlate With Pregnancy In Timed-Mated Rhesus Monkey Females (Macaca mulatta)

Creator:: Roth, Maggie
Abstract:: Infertility is an issue affecting millions of women across the globe, yet the causes are not fully understood, and treatment options are often ineffective. The evaluation of reproductive hormones has been a common tool used by fertility clinics as a way to predict the ovarian response to treatment and gain...
