Hydrogeologic field investigation and groundwater flow model of the southern Willamette Valley, Oregon

Creator:: Craner, Jeremy D.
Abstract:: Elevated groundwater nitrate (NO3 -) concentrations in the Southern Willamette Valley (SWV) caused the Oregon Department of Environmental Quality (ODEQ) to declare a Groundwater Management Area (GWMA) in Spring, 2004. To better understand direction of groundwater flow, groundwater age, and nitrate transport pathways of the SWV we developed a steady-state...

Charting their own course as writers : a study of writing-intensive students’ self-assessment and goal-setting at start of term

Creator:: Robinson, Tracy Ann
Abstract:: Curricular models and teaching techniques that support college students as the primary authors of their writing-across-the-curriculum experiences remain largely unexplored. This thesis addresses that research gap by investigating the use of a start-of-term writing self-assessment and goal-setting questionnaire (STQ) for upper-division undergraduates taking writing-intensive (WI) college courses in their majors....

Public acceptance of disturbance-based forest management : a study of the attentive public in the Central Cascades Adaptive Management Area

Creator:: Mallon, Angela L.
Abstract:: Growing emphasis on ecosystem and landscape-level forest management across North America has spurred an examination of alternative management strategies which focus on emulating dynamic natural disturbance processes, particularly those associated with forest fire regimes. This topic is the cornerstone of research in the Blue River Landscape Study (BRLS) taking place...

Preventing falls from unpredictable balance disturbances

Creator:: Welsh, Lisa R.
Abstract:: Falls, particularly those due to slips, constitute a major health risk for older adults. Past research has found that individuals can learn not to fall through repeated exposure to a slipping perturbation. Slips can be unpredictable, however. The goal of this study was to determine whether similar adaptations would occur...

Spawning, larval recruitment, and early life survival of Pacific lampreys in the South Fork Coquille River, Oregon

Creator:: Brumo, Abel F.
Abstract:: Recently, there has been concern over the decline of the Pacific lamprey, Lampetra tridentata, in the northwestern United States. However, effective management has been impeded by data gaps in basic biology, especially in the early life stages. Consequently, in 2004 and 2005 I examined reproductive ecology, larval recruitment, and lamprey...

Patterns of retention and vagrancy in larval Lost River and shortnose suckers from Upper Klamath Lake, Oregon

Creator:: Reithel, Susan A.
Abstract:: Larval transport and retention of two endangered suckers were studied in a highly altered lacustrine/riverine complex. The endangered populations of Lost River sucker, Deltistes luxatus, and shortnose sucker, Chasmistes brevirostris, in Upper Klamath Lake (UKL), Oregon are the largest remnant populations of these suckers. Downstream of UKL, the Keno Impoundment...

Early Oligocene intrusions in the central Coast Range of Oregon : petrography, geochemistry, geochronology and implications for the Tertiary magmatic evolution of the Cascadia forearc

Creator:: Oxford, Jeremiah
Abstract:: The Early Oligocene Oregon Coast Range Intrusions (OCRI) consist of gabbroic rocks and lesser alkalic intrusive bodies that were emplaced in marine sedimentary units and volcanic sequences within a Tertiary Cascadia forearc basin. The alkalic intrusions include nepheline syenite, camptonite, and alkaline basalt. The gabbros occur as dikes and differentiated...

Giant otters (Pteronura brasiliensis) and humans in the lower Yasuní Basin, Ecuador : spacio-temporal activity patterns and their relevance for conservation

Creator:: Carrera-Ubidia, Paola M.
Abstract:: Giant otters (Pteronura brasiliensis) and humans in the Lower Yasuní Basin (Ecuador) have similar food and space requirements: they consume comparable arrays of fish species, and they use similar aquatic and terrestrial habitats. Resource partitioning could facilitate coexistence by allowing each species exclusive access to some resources. My research examines...

Magma chamber processes over the past 475,000 years at Mount Hood, Oregon : insights from crystal zoning and crystal size distribution studies

Creator:: Darr, Cristina M.
Abstract:: Several different petrological techniques have been applied to lava flows between 200 to 475,000 years old from Mount Hood, Oregon. Mount Hood is unusual, in comparison to nearby Mount St. Helens and Mount Jefferson, in that it has produced relatively homogeneous lava compositions over 475,000 years. Erupted lavas are mostly...

Over-wintering diet, growth, and prey available to juvenile coho salmon (Oncorhynchus kisutch) in the West Fork Smith River, Oregon

Creator:: Olegario, Anthony
Abstract:: Over-winter growth of juvenile salmonids may be linked to ocean survival and thus species persistence. Diet, growth, and prey available to juvenile coho, Oncorhynchus kisutch, were examined from December 2004 to April 2005 in four tributaries of the West Fork Smith River (WFSR), Oregon. Juvenile coho growth rate and condition...
