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...

Determinants of public opinion on renewable energy : the case of wave energy development in Oregon

Creator:: Stefanovich Petrova, Maria A.
Abstract:: Renewable energy resources, such as wind, solar, and wave, have a number of advantages compared to traditional fossil fuels. Numerous studies attest to the physical potential for wave energy development in Oregon. In transitioning from conventional fossil fuel to alternative energy provision, citizen understanding of the global energy problems and...

Identification of optimal broodstock for Pacific Northwest oysters

Creator:: Stick, David A.
Abstract:: The United States Pacific Northwest is well known for its shellfish farming. Historically, commercial harvests were dominated by the native Olympia oyster, Ostrea lurida, but over-exploitation, habitat degradation, and competition and predation by non-native species has drastically depleted their densities and extirpated many local populations. As a result, shellfish aquaculture...

Anthropogenic activities associated with the status of salmon stocks in Pacific Northwest watersheds

Creator:: Mrakovcich, Karina Lorenz
Abstract:: Stocks of salmon are declining in the Pacific Northwest. Based on region-wide studies that list and categorize the status of salmon stocks (Nehlsen et al., 1991; Huntington et al., 1994; and Nawa, 1995), I analyze the watersheds where stocks of salmon spawn for several anthropogenic variables, most of which are...

Humpback Whale (Megaptera novaeangliae) Calling Behavior In Southeast Alaska : A Study In Acoustic Ecology And Noise

Creator:: Fournet, Michelle E. H.
Abstract:: Humpback whales (Megaptera novaeangliae) are a widely distributed baleen whale species, well known for their diverse acoustic behavior. On high-latitude foraging grounds, humpback whales produce a suite of non-song vocalizations (“calls”) in concert with foraging and social behavior. In this dissertation I investigated the role of calls in the acoustic...

Ecophysiology of Marine Bivalves : Physiological Rate Processes in Dynamic Environments

Creator:: Gray, Matthew W.
Abstract:: Marine bivalves are globally recognized as ecologically and commercially valuable species and, for over a century, researchers have been studying their feeding, digestion and other related physiological processes. These studies have shown that marine bivalves have complex feeding and particle processing behaviors to maximize growth in dynamic environmental conditions. Additionally,...

Sedimentary organic matter : distribution and alteration processes in the coastal upwelling region off Peru

Creator:: Reimers, Clare E.
Abstract:: Recent organic-rich deposits on the Peru continental margin occur along the upper slope (100-450 m) between about ll°S and 16°S and along the lower continental slope (>2000 m). The upper slope deposits reflect high biological production in response to coastal upwelling, but preservation of organic matter is enhanced by the...

Structure and Dynamics of Northeastern Pacific Demersal Fish Assemblages

Creator:: Gabriel, Wendy Louise
Abstract:: Regions of similar species composition and groups of demersal fish species with similar distribution patterns from Cape Flattery, Washington to Point Hueneme from 50-250 fm (93-460 rn) were defined based on results of an agglomerative cluster analysis of National Marine Fisheries Service Rockfish Survey data taken during the summer of...

Sea urchin-kelp forest communities in marine reserves and areas of exploitation : community interactions, populations, and metapopulation analyses

Creator:: Moctezuma, Gabriela Montaño
Abstract:: Marine ecosystems can be exposed to natural and anthropogenic disturbances that can lead to ecological failures. Marine reserves have been lately suggested to protect marine populations and communities that have been affected by habitat destruction and harvest. This research evaluates the potential role of two marine reserves established in Oregon...

Bioeconomic Simulation Modeling of Fisheries : Three Essays

Creator:: Cusack, Christopher Inju
Abstract:: Researchers rely on bioeconomic models to guide research and generate fishery management advice for commercial fisheries. Due partly to a paradigm shift towards ecosystem based fishery management, increasing complexity in the characteristics of the problems has meant that bioeconomic simulation models are becoming more prevalent in the fisheries literature. However...
