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...

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...

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...

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...

The Role of Seagrass Traits in Mediating Zostera noltei Vulnerability to Mesograzers

Creator:: Martínez-Crego, Begoña, Arteaga, Pedro, Tomas, Fiona, and Santos, Rui
Abstract:: Understanding how intra-specific differences in plant traits mediate vulnerability to herbivores of relevant habitat-forming plants is vital to attain a better knowledge on the drivers of the structure and functioning of ecosystems. Such studies, however, are rare in seagrass-mesograzer systems despite the increasingly recognized relevance of mesograzers as seagrass consumers....

The tropicalization of temperate marine ecosystems: climate-mediated changes in herbivory and community phase shifts

Creator:: Vergés, Adriana, Steinberg, Peter D., Hay, Mark E., Poore, Alistair G. B., Campbell, Alexandra H., Ballesteros, Enric, Heck, Kenneth L., Booth, David J., Coleman, Melinda A., Feary, David A., Figueira, Will, Langlois, Tim, Marzinelli, Ezequiel M., Mizerek, Toni, Mumby, Peter J., Nakamura, Yohei, Roughan, Moninya, van Sebile, Erik, Sen Gupta, Alex, Smale, Dan A., Tomas, Fiona, Wernberg, Thomas, and Wilson, Shaun K.
Abstract:: Climate-driven changes in biotic interactions can profoundly alter ecological communities, particularly when they impact foundation species. In marine systems, changes in herbivory and the consequent loss of dominant habitat forming species can result in dramatic community phase shifts, such as from coral to macroalgal dominance when tropical fish herbivory decreases,...

Metagenomics and metatranscriptomics of the leaf- and root-associated microbiomes of Zostera marina and Zostera japonica

Creator:: Wojahn, John Michael Adrian
Abstract:: A great deal of research has been focused on the microbiomes of terrestrial angiosperms (flowering plants), but much less research has been performed on the microbiomes of aquatic angiosperms (Turner et al. 2013). Eelgrass beds are extremely productive ecosystems that provide habitat for many marine organisms, such as fish, shellfish,...

Professional Development Training in Ocean Acidification: A Case Study of Marine Resource Managers

Creator:: Moses, Michael L.
Abstract:: Ocean acidification (OA) is the result of increasing concentrations of anthropogenic carbon dioxide (CO₂) emissions, leading to a suite of alterations to specific parameters of ocean chemistry, which can negatively impact many marine organisms and ecosystems. Understanding how to measure and monitor the chemistry of OA will require specialized education...
