Ecological Effects of Reservoir Water Level Management and Implications for Juvenile Chinook Salmon

Creator:: Murphy, Christina A.
Abstract:: Large dams and their respective reservoirs can provide renewable energy and water security, but also profoundly alter riverine ecosystems. In the Pacific Northwest, dams and reservoirs cause discontinuities in river networks that have been particularly problematic for anadromous fishes. As barriers to the upstream and downstream migration of anadromous fishes,...

Honey Bees and Apple Trees : Hood River, Oregon as a Case Study for the Creation of the Honey Bee Pollination Industry

Creator:: Kellar, Brenda M.
Abstract:: The use of honey bees to pollinate apple orchards seems natural, even inevitable. This dissertation examines the relationship of beekeeping and apple growing in Hood River, Oregon in the mid-nineteenth to the mid-twentieth centuries, as a case study in the development of commercial pollination service. Within this time period the...

Feeding Ecology and Growth of Juvenile Chinook Salmon (Oncorhynchus tshawytscha) During Early Marine Residence

Creator:: Litz, Marisa Norma Chantal
Abstract:: The early marine phase following freshwater emigration has been identified as a critical period in salmonid (Oncorhynchus spp.) life history, characterized by high but variable mortality. Consistent with the “growth-mortality” and “bigger-is-better” hypotheses, at least some of the mortality during the critical period appears to be size-dependent – with smaller...

Distribution, Abundance, and Settlement of Slope-spawning Flatfish during Early Life Stages in the Eastern Bering Sea

Creator:: Sohn, Dongwha
Abstract:: Changes in environmental conditions in marine ecosystems could directly or indirectly influence distribution, abundance, settlement, and size at settlement of flatfish. Understanding species-specific and age-specific responses to environmental variability is important for managing commercially important flatfish stocks. Slope-spawning flatfish whose offspring rely on extensive drift from the slope (spawning) to...

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...

Genomics of migration : from marine distributions of salmonids to mechanisms of olfactory and magnetic cue perception for natal homing

Creator:: Bellinger, M. Renee
Abstract:: Substantial scientific investment has been directed towards understanding factors that influence distribution patterns and animals' remarkable ability for precise orientation and navigation, yet fundamental gaps in our knowledge remain. In my dissertation, I applied emerging genetic technologies to conduct a top-down and bottom-up investigation of animal movement and cue perception....

Personalizing machine learning systems with explanatory debugging

Creator:: Kulesza, Todd
Abstract:: How can end users efficiently influence the predictions that machine learning systems make on their behalf? Traditional systems rely on users to provide examples of how they want the learning system to behave, but this is not always practical for the user, nor efficient for the learning system. This dissertation...

Bioenergetics and behavior of the krill Euphausia pacifica in the California Current System off the Oregon coast

Creator:: Lindsey, Brie J.
Abstract:: Euphausia pacifica, the North Pacific krill, is a key grazer in the California Current System and an important prey item for consumers such as salmon, seabirds, and whales. As a crucial link between phytoplankton and higher trophic levels, it is essential to understand both the behavior and bioenergetics of this...

Sandy beach surf zones : what is their role in the early life history of Chinook salmon (Oncorhynchus tshawytscha)?

Creator:: Marin Jarrin, Jose R.
Abstract:: Early life stages of many marine and diadromous fish species use sandy beach surf zones, which occur along >50% of the world's marine coastlines. This extensive habitat can provide juvenile fishes with an abundant supply of potential prey and the ability to hide from predators in its shallow turbid waters....

Beyond the paired-catchment approach : isotope tracing to illuminate stocks, flows, transit time, and scaling

Creator:: Hale, V. Cody
Abstract:: This dissertation integrates a process-based hydrological investigation with an ongoing paired-catchment study to better understand how forest harvest impacts catchment function at multiple scales. We do this by addressing fundamental questions related to the stocks, flows and transit times of water. Isotope tracers are used within a top-down catchment intercomparison...
