Influence of the Environment and Morphology on Physiological and Genomic Homeostasis in a Temperate Cnidarian-microbe Symbiosis

Creator:: Koch, Jack C.
Abstract:: Climate change and other anthropogenic impacts are threatening the existence of millions of species around the globe. On western continental boundaries, the large-scale secondary process of upwelling, which brings low pH, deoxygenated, high nutrient seawater to the surface, is compounded by climate change, that together could drive some species to...

Carbon storage in U.S. Pacific Northwest coastal dunes : the role of invasive beachgrasses and sand supply

Creator:: Stepanek, John
Abstract:: As global atmospheric carbon emissions continue to rise, scientists and land managers are increasingly looking to natural ecosystems to sequester and store carbon to buffer the impacts of climate change. Despite their small geographic size, many coastal ecosystems such as salt marshes, seagrass meadows, and mangroves sequester large amounts of...

Investigating the Role of Dune Grasses, Carbon Storage, and Marine Nutrient Subsidies to the Functions and Services of U.S. Central Atlantic Coastal Dune Ecosystems

Creator:: Jay, Katya R.
Abstract:: Sandy beaches and dunes cover approximately one-third of the world’s ice-free coastlines and provide ecosystem services including coastal protection, recreation, wildlife habitat, and carbon sequestration. These dynamic interface habitats are variably shaped by wind, waves, sedimentary processes, and vegetation feedbacks. Positive biophysical feedbacks lead to the formation of vegetated coastal...

Ecosystem Functions of Pacific Northwest Estuaries: The Role of Ocean and Watershed Drivers in Eelgrass and Coho Salmon Dynamics

Creator:: Magel, Caitlin L.
Abstract:: Interest is expanding for the potential role of estuaries, particularly seagrass and salt marsh habitats, to sequester carbon, mitigate ocean acidification, and support abundant fisheries. The important functions of estuaries are part of a broader set of ecosystem services, or benefits to humans, which are regulated by ocean and watershed...

Grazer-resource Behavior, Interactions, and Feedbacks Control Kelp-forest Dynamics and Stability

Creator:: Randell, Zachary H.
Abstract:: How the direct and indirect effects of species interactions cascade to affect community structure, functioning, and stability is a fundamental question in ecology. In temperate kelp forests, species interactions, in conjunction with environmental processes, produce rich spatiotemporal dynamics. Arguably the most dramatic of these are abrupt shifts in community state,...

Coastal Dunes as Meta-Ecosystems: Connecting Marine Subsidies to Dune Ecosystem Functions on the U.S. Pacific Northwest Coast

Creator:: Constant, Vanessa
Abstract:: Ecological communities are connected in space and time through the transfer of energy, materials, and organisms, together known as ecological subsidies. These ecological subsidies can have substantial effects on community structure, function, and services, especially when the connections are between communities with contrasting productivity. At the ocean-land interface, low productivity...

Scale and Pattern: Delineating the Effects of Local to Regional Processes and Species Identity in Producing Multi-scale Responses of Macroalgae

Creator:: Spiecker, Barbara J.
Abstract:: Understanding and predicting how regional to global scale processes affect macroalgal populations and communities requires elucidating the mechanisms underlying observed patterns. This dissertation identifies some of the underlying mechanisms that produce complex multi-scale responses of macroalgae across space and time by delineating the role of key local environmental drivers and...

The Roles of Recruitment, Species Interactions, and Oceanographic Context in Structuring Rocky Intertidal Communities of the Pacific Northwest and Atlantic Canada

Creator:: Meunier, Zechariah D.
Abstract:: Long-term, large-scale studies of meta-ecosystems provide critical information about how global change influences communities. In my dissertation, I analyzed data from studies encompassing 18 years (2006 – 2023) and over 1,000 km of coastline to investigate drivers of rocky intertidal community structure and dynamics. Specifically, I explored the roles of...

Hybridization of Non-Native Dune-Building Beachgrasses on the U.S. Pacific Northwest Coast: Characterization of Functional Morphology, Hybrid Swarm Composition, and Ecological Consequences of Ammophila arenaria × A. breviligulata

Creator:: Mostow, Rebecca S.
Abstract:: The rates of biological introductions and invasions are increasing, driving up the associated harms to ecosystems and economies. The spread and effects of invasive organisms depend on the specifics of the introduction, the character of the invaded ecosystem, and multiple traits of the invasive organism itself. One mechanism by which...

Genetic Structure, Diversity, and Mating System of Leptasterias: Potential for Local Adaptation?

Creator:: Boring, Emily L.
Abstract:: Understanding of gene flow, connectivity, and diversity is critical to predict the stability of key marine species. The Oregon coast of the U.S.A. shows fine-scale levels of geographic variation in environmental stressors such as temperature, pH, and oxygen levels, prompting questions about the potential for local adaptation. In this thesis,...
