Local and Regional Patterns in Eelgrass (Zostera marina L.) Communities Along an Upwelling-Productivity Gradient in Oregon Estuaries, USA

Creator:: Motley, Jennifer
Abstract:: In this thesis, I investigate the organization of eelgrass (Zostera marina L.) and mesograzer communities across local and regional scales in three upwelling- influenced estuaries located along the Oregon coast, USA. Eelgrass ecosystems are an important source of primary production in estuarine systems, providing numerous ecosystem services, including nursery habitat...

Of Mysid and Menidia: Sublethal Effects of Micro and Nanoplastics on Estuarine Indicator Species

Creator:: Dickens, John
Abstract:: Microplastics are widely distributed in aquatic environments. The term ‘microplastics’ encompasses a wide array of particles with unique polymer constituents, morphologies, and sources, such as automobile tire tread. Tire wear particles (TWP) can end up in waterways near densely populated municipalities, where they can interact with aquatic biota. Studying the...

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...

On the Edge : Assessing Fish Habitat Use Across the Boundary between Pacific Oyster Aquaculture and Eelgrass in Willapa Bay, WA

Creator:: Muething, Kelly A.
Abstract:: Estuaries are an important ecological link between terrestrial, freshwater, and marine systems, but are also subject to a variety of human pressures. Along the West Coast of the United States, shellfish aquaculture is one extensive use of estuarine tidelands. Specifically, Pacific oyster (Crassostrea gigas) aquaculture has been practiced for almost...

Effects of Anthropogenic Stressors on Seagrass and Coral Microbiomes

Creator:: Wang, Lu
Abstract:: Seagrasses and coral reefs play important roles in nutrient cycling, coastal protection, and maintaining marine biodiversity. However, these coastal marine organisms are declining globally due to anthropogenic stressors, such as rising ocean temperatures, ocean acidification, and eutrophication. These organisms live in close association with their microbiomes, which can be beneficial...

Juvenile Pacific Oyster Growth and Food Resources in Eelgrass Habitats of Variable Shoot Density in Tillamook Bay, OR: Ecosystem Interactions for Management Consideration

Creator:: Merrill, Julianne
Abstract:: As the global demand for seafood increases each year, there is a growing need to expand sustainable aquaculture in the interests of food security and resilience of coastal communities. Pacific oysters, Crassostrea gigas, are grown in West coast estuaries - where cultures often overlap with the federally protected native eelgrass,...

Amphibian communities and climate change : Where ecological processes meet evolutionary interactions

Creator:: Thurman, Lindsey L.
Abstract:: Forecasts of the impacts of climate change have traditionally focused on individual species and their phenotypes, phenology, or distribution. However, shifts in species distributions and the resulting reorganization of community composition represent an important violation to the assumption of species acting in isolation. Whereas species may respond individualistically to climate...

Function of Oregon Estuaries to Juvenile Fishes, with Focus on Juvenile Rockfishes (Sebastes spp.) in Yaquina Bay, Oregon

Creator:: Schwartzkopf, Brittany D.
Abstract:: The role that anthropogenic and natural habitats in estuaries play in long-term population trends for Oregon’s nearshore marine fishes is poorly understood, in part due to limited temporal sampling. One important nearshore marine group is northeastern Pacific rockfishes (Sebastes spp.), which are highly diverse, with around 96 documented species, and...

Evidence for regional‐scale controls on eelgrass (Zostera marina) and mesograzer community structure in upwelling‐influenced estuaries

Creator:: Hayduk, Jennifer L., Hacker, Sally D., Henderson, Jeremy S., and Tomas, Fiona
Abstract:: Community structure and function in ecosystems are dependent on top‐down and bottom‐up factors, which vary across local, regional, and temporal scales. In estuaries of the U.S. Pacific Northwest coast, eelgrass (Zostera marina) ecosystems are exposed to latitudinally varying oceanographic inputs in the form of ocean upwelling. Previous research suggests that...

Spatial Variation in Ecosystem Carbon Stocks and Emissions Resulting from Land-use Conversion: Two Studies in Mangrove Forests of the Dominican Republic

Creator:: Giovannoni, Leila R.
Abstract:: Mangrove forests store more organic carbon across ecosystem carbon pools than most other coastal and forested ecosystems, and are subject to high global rates of deforestation. For these reasons, they are recognized as prime candidates for inclusion in climate change mitigation strategies. However, the ecological drivers of regional and micro-scale...
