Investigation of hop downy mildew through association mapping and observations of the oospore

Creator:: Parker, Thomas B.
Abstract:: Hop downy mildew is a devastating disease affecting hop requiring expensive fungicide applications throughout the growing season. Plant resistance is highly desirable and theorized as being decidedly quantitative with dominance and epistasis involved in resistance. An association mapping approach using a mixed-model was used to identify AFLP markers associated with...

Habitat use and productivity of Rio Grande wild turkey hens in southwestern Oregon

Creator:: Keegan, Thomas W.
Abstract:: Wild turkey (Meleagris gallopavo) ecology has been examined within its native range, but knowledge of extralimital populations of Rio Grande wild turkeys (M. g. intermedia) is lacking. I investigated habitat use, characteristics of activity sites, home ranges and movements, productivity, and survival of Rio Grande turkey hens from 1989 through...

The economic impacts of sagebrush steppe wildfires on an eastern Oregon ranch

Creator:: Maher, Anna T.
Abstract:: The relative success of restoration practices on cheatgrass infested sagebrush steppe lands in the Great Basin can affect the probability of crossing an ecological threshold and have economic effects on cattle ranches using federal rangelands. Cheatgrass invasion implies an increase in the risk of fire, which in turn increases the...

Inner-shelf circulation off the central Oregon Coast

Creator:: Kirincich, Anthony R.
Abstract:: Inner-shelf circulation and mechanisms of across-shelf transport of water masses were examined using seven years of observations collected by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) program, a long-term monitoring effort along the central Oregon coast. Since 1998, moored velocity and hydrographic measurements have been obtained during the...

Systems evaluation of the Guatemalan eye care project – Enfoque Ixcan : barriers and avenues for providing eye care services to rural Guatemala

Creator:: Terhes, Amanda Foshay
Abstract:: This thesis evaluates the programs, activities, and relationships of Enfoque Ixcan, a non-profit eye care project providing services to a rural area of Guatemala. I conducted ethnographic interviews with key stakeholders of the organization and carried out participant observation in the Ixcan region of Guatemala in February 2006. The research...

Toxic politics at 64N, 171W : addressing military contaminants on St. Lawrence Island, Alaska

Creator:: Henifin, Kai A.
Abstract:: St. Lawrence Island, Alaska is home to two Formerly Used Defense Sites (FUDS) under remediation by the U.S. Army Corps of Engineers since 1985. After more than two decades the local residents continue to be concerned about inadequate site characterization and cleanup. During the summer of 2005, I collected ethnographic...

Economic and social impacts of restoration : a case study of the Great Basin Region

Creator:: Satyal, Vijayanand H.
Abstract:: The last five decades of research in arid land ecology cites Invasive species as a source of imbalances in biodiversity through habitat destruction and reductions of native species through ecosystem alterations in favor of non-native species. Invasive species are known to damage not only the surrounding ecosystem but also cause...

Coastal ocean response to alongshore variations in topography and wind forcing

Creator:: Castelao, Renato Menezes
Abstract:: The effects of alongshore variability in topography (banks and capes) and spatial variability in the wind forcing, including the wind-stress curl, on coastal ocean circulation are studied using a combination of observations and model simulations. Satellite sea surface temperature observations are used to describe the seasonal evolution of temperature fronts...

Integration of oceanographic information off the Washington and Oregon coasts into west coast groundfish ecology and fisheries management

Creator:: Juan Jorda, Maria Jose
Abstract:: To date, the use of oceanographic data in fisheries management has been limited by the scarcity and the difficulty of accessing complete oceanographic datasets. Consequently, fish stocks are managed with limited knowledge about the habitat where fish live and incomplete understanding of what oceanographic conditions affect their populations. With the...
