Functional Comparison of Longline Oyster Aquaculture and Eelgrass (Zostera marina L.) Habitats Among Pacific Northwest Estuaries, USA

Creator:: Clarke, Larissa M.
Abstract:: Understanding the ecological role of Pacific oyster aquaculture (Crassostrea gigas) and eelgrass (Zostera marina L.) as important habitats in US Pacific Northwest estuaries is critical for management and regulatory decisions. The oyster aquaculture industry is currently restricted by regulations concerning impacts of their activities on Z. marina. This seagrass is...

Spatial Association of Humpback Whales (Megaptera novaeangliae) and their Prey in the Southern Gulf of Maine, USA

Creator:: Kirchner, Theresa
Abstract:: Efficient foraging strategies result in a predator spatially overlapping with its prey, foraging in the most profitable patches, and minimizing the time transiting between patches. Previous studies investigating baleen whale foraging strategies have generally focused on investigating spatial overlap with prey patches, patch profitability or movement within feeding grounds. The...

The Soundcheck of the Sea : Comparing Marine Soundscapes on a Continental Scale

Creator:: Haver, Samara M.
Abstract:: Monitoring marine ambient sound using standardized methods supports assessments of ocean sound levels across widespread ecosystems. This thesis quantifies differences among coastal and deep-water marine soundscapes in the Atlantic and Pacific oceans. The sources of sound in a soundscape are compartmentalized into three components and compared over time and among...

The Behavioral Responses of Western Toad (Anaxyrus boreas) Larvae to Simultaneous Stressors

Creator:: Reynolds, Emily R.
Abstract:: Animals can be naturally exposed simultaneously to multiple stressors. These include habitat changes, contaminants, diseases, invasive species, parasitism, and predation. Exposure to various combinations of biotic and abiotic stressors may induce behavioral changes that affect the way an individual interacts within its environment.Like other groups of organisms, amphibians are exposed...

The Effects of Host and Pathogen Variation on Infection Dynamics in the Amphibian-Chytrid System

Creator:: Dang, Trang D.
Abstract:: This dissertation uses manipulative experiments to explore amphibian-Bd infection dynamics. Although there has been almost two decades research since the discovery of Bd, many questions still remain regarding what conditions mediate chytridiomycosis virulence. My research shows how certain host and pathogen factors can influence disease virulence. Identifying how host and...

The role of oxygen and other environmental variables on survivorship, abundance, and community structure of invertebrate meroplankton of Oregon nearshore coastal waters

Creator:: Eerkes-Medrano, Dafne I.
Abstract:: The high productivity of Eastern Boundary Upwelling Ecosystems (EBUE), some of the most productive ecosystems in the globe, is attributed to the nutrient rich waters brought up through upwelling. Climate change scenarios for coastal upwelling systems, predict an intensification of coastal upwelling winds. Associated with intensification in upwelling are biogeochemical...

Host-pathogen Interactions of Respiratory RNA Viruses and the Application of Recombinase Polymerase Amplification for Viral Diagnostics

Creator:: Prescott, Meagan A.
Abstract:: Humans and viral disease are inextricably intertwined. Viral disease plays an immeasurable role in human life, from the disease and economic burden associated with every facet of contending with human viral disease, to managing the consequences of viral disease in organisms important to our food supply, economy, and entertainment. The...

Movement Patterns of Rockfishes at the Redfish Rocks Marine Reserve, Oregon

Creator:: Calvanese, Thomas P.
Abstract:: The effects of Marine protected areas (MPAs) on adult fish populations depend on the degree of protection provided, which is partly a function of MPA size and the spatial extent of fish movements. The Redfish Rocks Marine Reserve (RRMR) and MPA, located on the south coast of Oregon near Port...

Effects of Elevated CO₂ on Speckled Sanddab (Citharichthys stigmaeus) Behavior

Creator:: Andrade, Jessica F.
Abstract:: The direct and indirect effects of ocean acidification (OA) are a growing concern, particularly in areas already experiencing elevated levels of oceanic CO₂. Studies with marine fishes suggest that elevated CO₂ levels may affect behavior by interfering with an important brain neurotransmitter. Studies examining the effects of OA fish behavior...

An Integrated Approach to the Investigation of Age, Growth and Population Dynamics of Burrowing Thalassinidean Shrimps in a U.S. West Coast Estuary

Creator:: Bosley, Katelyn Marie
Abstract:: Two indigenous species of burrowing shrimp inhabit and often dominate the intertidal zone of estuaries along the US West Coast, the ghost shrimp, Neotrypaea californiensis, and the blue mud shrimp, Upogebia pugettensis. Both species are considered ecosystem engineers and play a role in maintaining estuarine health and ecosystem function. They...
