An edaphic study of the Mt. Pisgah Arboretum water garden, Coast Fork of the Willamette River

Creator:: Bergen, Cameron Francis
Abstract:: Wetlands are widely identified as providing important and fundamental processes valuable for maintaining ecosystem health and diversity. Located in the southern Willamette Valley, the Mt. Pisgah Arboretum contains some valuable remaining wetland habitat along the Coast Fork of the Willamette River. One goal of the Mt. Pisgah Arboretum is "to...

How Behavior, Physiology, and Ontogeny of Klamath Redband Trout Shape the Functionality of Habitats in a Landscape of Temperature Extremes

Creator:: Hahlbeck, Nicholas J.
Abstract:: Climate change is a global phenomenon, but natural selection occurs within landscapes. A central tenet of landscape ecology is that mobile species depend on complementary habitats, which are insufficient in isolation, but combine to support animals through the full annual cycle. For coldwater fishes, it is widely assumed that maximum...

A Trend Analysis of Nitrate in the Southern Willamette Valley Groundwater Management Area (GWMA)

Creator:: Piscitelli, Cody M.
Abstract:: The shallow aquifer in Southern Willamette Valley (SWV) has high levels of nitrate, and we are exploring the time trends in nitrate, and the hydrologic and land management factors that contribute to this problem. Nitrogen (N) inputs to farmland from fertilizer is thought to be the primary source of nitrogen...

Robotic Actuation and Control with Programmable, Field-Activated Material Systems

Creator:: Bira, Nicholas P.
Abstract:: This dissertation presents novel, field-activated smart material systems for the actuation and control of autonomous robots. Smart materials, a type of material whose properties can be changed with an external stimuli, represent a promising direction to expand upon existing robotic control and actuation methods, particularly in the sub-fields of soft...

Forensic Hydrogeography : Assessing Groundwater Arsenic Concentrations and Testing Methods within the Harney Basin, Oregon

Creator:: Smitherman, Lauren L.
Abstract:: Harney County contains defining characteristics of regions containing arsenic within the groundwater such as its location in the western United States, unique closed basin geography, complex geology, and seasonal groundwater level fluctuations. Confirmation of arsenic concentrations above the Maximum Contaminant Level Drinking Water Standard of 10 μg/L has been observed...

Ceratomyxa shasta-related concerns for reintroduced anadromous salmonids into the Upper Klamath Basin, CA-OR, USA

Creator:: Hurst, Charlene N.
Abstract:: The myxozoan parasite of salmonids, Ceratomyxa shasta, is established throughout the Klamath River, CA-OR, with high parasite densities below the series of dams and above the dams (upper basin) in the northernmost tributary, the Williamson River (WMR). Two objectives were designed to address concerns about C. shasta effects on reintroduced...

A preliminary assessment of hydrogeologic suitability for Aquifer Storage and Recovery (ASR) in Oregon

Creator:: Woody, Jen
Abstract:: An ASR metric and site rating index applied to over 120 municipal and agricultural locations across Oregon, combined with comparison to case study data from existing ASR sites, indicate that more than 50% of selected sites are hydrogeologically suitable for ASR. The ASR metric is a ratio of aquifer storage...

Testing the effectiveness of barley stripe rust resistance QTL detected in Mexico and the USA against a possible new race in Peru and mapping of genes conferring resistance to leaf rust and mildew in the same population

Creator:: Rossi, Carlos
Abstract:: Barley is the fourth most important cereal crop in the world because of its broad adaptation, its utility as a feedstock and for human food, and the superior properties of barley malt for brewing. Three of the most important foliar diseases of barley, on a worldwide level are: barley leaf...

Membrane-type matrix metalloproteinase and inhibitor expression in sheep embryos and uterus

Creator:: Paul, Katy Beth
Abstract:: Expression of membrane-type matrix metalloproteinases (MT) and tissue inhibitors of matrix metalloproteinases (TIMP) was evaluated in sheep embryos and uterus during the pre- and peri-implantation periods. Embryos and uterine samples were surgically collected from ewes on days 9, 11, 13, and 15 of pregnancy (n=3 ewes/day) and of the estrous...

Stream channel stability and sensitivity to landscape history and land use changes in Kelley Creek, Portland, Oregon

Creator:: Murphy, Yarrow M.
Abstract:: This study examines stream channel erosion processes in a small urbanizing watershed influenced by deposits of the Columbia Basin catastrophic floods: Kelley Creek, a 12-km² tributary of Johnson Creek, located just east of Portland, Oregon. Information on landscape history, stream channels, and sediment dynamics was compiled. The effects of future...
