Surface water variation and water storage potential in Upper Klamath Basin, 2000-2012

Creator:: Tanner, Andrew M.
Abstract:: With too many demands placed on too little water, the Klamath Basin and itsresidents - human and otherwise - are in dire need. There exists a significant opportunityfor mitigation in the purposeful conversion of seasonal wetlands to permanent wetlandsmanaged to increase baseline water storage levels in the Upper Basin. A...

Associations Between Crested Wheatgrass and Native Vegetation in Southeastern Oregon : An Investigation of Co-establishment, Environment, Seeding History, and Livestock management

Creator:: Nafus, Aleta M.
Abstract:: Crested wheatgrass (Agropyron cristatum [L] Gaertm), an introduced bunchgrass, has been seeded on over 5 million hectares of degraded rangeland in western North America because it establishes more readily than native bunchgrasses. Because crested wheatgrass stands are associated with native species displacement and low biological diversity, there is substantial interest...

Integrated small broomrape (Orobanche minor Sm.) management in red clover (Trifolium pratense L.)

Creator:: Ross, Kyle C.
Abstract:: Small broomrape, a holoparasitic weed, is a relatively new weed introduction in the Pacific Northwest that has contaminated a limited number of red clover fields in Oregon. Greenhouse and field studies were conducted to evaluate small broomrape response to common crop and weed species in the Pacific Northwest. Host species...

Effects of fire on seedling establishment in upland prairies in the Willamette Valley, Oregon

Creator:: Maret, Mary P.
Abstract:: Prior to European settlement, native prairie dominated the landscape of the Willamette Valley. Today, due to urbanization, agriculture, and the cessation of burning, only isolated remnants of these grasslands still exist. In response to conservation concerns, there has been a move to restore the remaining prairies in the Willamette Valley,...

An opioid-like receptor in the roughskin newt, Taricha granulosa

Creator:: Walthers, Eliza A.
Abstract:: The main objectives of the current study were to obtain the complete cDNA sequence of an opioid-like receptor from an amphibian, the roughskin newt, Taricha granulosa, and investigate the receptor's tissue distribution and regulation following chronic exposure to the glucocorticoid corticosterone (CORT). Degenerate primers designed in highly conserved regions of...

Detecting medusahead (Taeniatherum caput-medusae (L.) Nevski) using high frequency, sequential, globally positioned digital images

Creator:: Ndzeidze, Stephen Koghan
Abstract:: Invasive plant species are expanding and transforming vegetative communities across Oregon and throughout the United States. Over the past three decades remote sensing, geographic information system (GIS), and Global Positioning System (GPS) technologies have been integrated to detect and map the distribution of noxious rangeland plants. This study developed low-cost...

Modeling phosphorus sequestration and release in an Upper Klamath Basin wetland

Creator:: Mulford, Emily L.
Abstract:: Upper Klamath Lake (UKL) and Agency Lake (AL) in southern Oregon are both hypereutrophic, in large part due to natural and anthropogenic loading of phosphorus (P), resulting in annual blooms of blue-green algae. Reduction of P loading to the lake is considered crucial to reduce the blue-green algae blooms, maintain...

Supercritical fluid impregnation of wood-based composites

Creator:: Acda, Menandro N.
Resource Type:: Dissertation

Identification and quantitation of 4-hydroxy-2-nonenal and 4-oxo-2-nonenal metabolites in vivo as biomarkers of oxidative stress

Creator:: Kuiper, Heather C.
Abstract:: Oxidative stress occurs when the balance between reactive oxygen species and antioxidant defense mechanisms in the body becomes tipped heavily in favor of the reactive oxygen species. Reactive oxygen species can be present in excess due to elevated O2 levels, radiation, infection, smoking, or even excessive exercise. It is also...

Linking greater sage-grouse habitat use and suitability across spatiotemporal scales in central Oregon

Creator:: Freese, Mark T.
Abstract:: Greater Sage-grouse (Centrocercus urophasianus) habitat research has historically focused on fine-scale (0.007 - 0.032 ha) vegetation structure and composition immediately surrounding sites selected by birds. However, little work has evaluated vegetation attributes important for Greater Sage-grouse at a landscape-scale or identified landscape attributes that influence habitat use patterns. Habitat use...
