Conservation programs from the farmer's perspective : where is the greener grass?

Creator:: Gibson, Jennifer S.
Abstract:: On the national level, landowners demand for conservation programs like EQIP and WRP has far outstripped federal funding in 2001. Yet within Oregon's Willamette Valley, both EQIP and CREP have had a rough time gaining momentum. Much of the past research on rural landowners' conservation participation has relied on surveys...

Interactions Between Wild Bee Communities and Douglas-fir Beetle (Dendroctonus pseudotsugae) Populations in Douglas-fir (Pseudotsugae menziezii) Forests of the Intermountain West

Creator:: Foote, Gabriel G.
Abstract:: This work combines both applied and basic research regarding previously undescribed relationships between two ecologically and economically important insect groups in coniferous forests, bark beetles (Coleoptera: Curculionidae, Scolytinae) and wild bee (Hymenoptera: Apiformes) communities in Western North America. Across the continent, native bark beetle outbreaks are key drivers of structural...

Intestinal Lesions and Parasites Associated with Senescence and Prespawn Mortality in Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Nervino, Stephanie A.
Abstract:: Pre-spawning mortality (PSM) presents a major problem for population recovery of spring Chinook salmon (Oncorhynchus tshawytscha) in the Willamette River basin. In certain reaches and years, PSM has exceeded 90%. Histology has been used as the primary diagnostic method to investigate PSM in the Chinook Salmon, and a collection of...

Understanding the Impact of Global Warming on Orographic Rain Shadows: Insights from a Pseudo-Global Warming Simulation over the Western United States

Creator:: Koszuta, Matthew
Abstract:: Some studies using regional climate models (RCMs) suggest a weakening of the climatological rain-shadow along the Cascade and Sierra Nevada mountains during the western US cool-season. To identify the possible mechanisms of rain-shadow weakening under warming, a new set of 30-year, high-resolution (6 km) pseudo-global warming (PGW) simulations were analyzed...

Cosmovisions and Farming : An Investigation of Conventional and Alternative Farmers' Environmental Values along the Willamette River

Creator:: French, Melissa M.
Abstract:: Understanding which factors motivate farmers to adopt certain practices is an important part of helping to solve many agri-environmental issues. This study uses 19 interviews with farmers along Oregon’s Willamette River, a statewide producer survey, and select interviews with organizations and agencies active in the farming community to examine the...

Mitigating cyanobacterial harmful algae blooms : the role of plant humics

Creator:: Theis, Susan A. F.
Abstract:: Cyanobacterial harmful algae blooms (cyanoHABs) are a growing concern worldwide due to damage of ecosystems and threats to human health. Previous research indicates that plant humics from aquatic and wetland vascular plants are effective inhibitors of cyanobacterial metabolism and growth and may be useful as control agents for mitigating cyanoHABs....

Greater sage-grouse movements and habitat use during winter in central Oregon

Creator:: Bruce, Jennifer R.
Abstract:: Greater sage-grouse (Centrocercus urophasianus), a sagebrush obligate species, has contracted in extent by nearly half its original distribution. This is primarily due to habitat loss and degradation over the past 150 years. During winter, sage-grouse depend completely on sagebrush habitat for food and cover, yet sage-grouse winter ecology has been...

An Archaeological Analysis of the Architectural Artifacts and Features at the Robert Newell Homestead Site (35MA41)

Creator:: Modelski, Emily
Abstract:: This thesis will explore the architectural material culture excavated at the Robert Newell Homestead (35MA41), currently located in Champoeg, Oregon. Specifically, the research focuses on the vernacular architecture or the features and construction methods used that both reflect the environment and the cultural traditions of the dwellings occupants. The Robert...

Early maturing males in a partially migratory population of anadromous and resident rainbow trout Oncorhynchus mykiss: influences of individual condition and stream temperature

Creator:: McMillan, John R.
Abstract:: Alternative male phenotypes in salmonine fishes arise from individuals that mature as either larger and older anadromous marine-migrants or as smaller and younger freshwater residents. Variability in age and size of males at maturity is hypothesized to be preceded by early differences in growth in size and lipid storage. Water...

Changing pastoral lifeways in the land where the horse was king : the effects of China's Grassland Contract Policy on Mongolian herders' attitudes towards grassland management and cooperation

Creator:: Conte, Thomas J.
Abstract:: This thesis explore the effects of China's Grassland Contract policy on sedentary and mobile Inner Mongolian pastoralists' attitudes towards cooperation, current grassland management practices, and the future viability of livestock herding in New Barag Right Banner, Inner Mongolia. Semi-structured interviews, a scaled survey instrument, and participant observation were carried out...
