Stress and Learning in Larval Zebrafish (Danio rerio)

Creator:: Moussaoui, Bushra
Abstract:: In this study, we characterize the behavioral response of larval zebrafish (Danio rerio) to the noxious chemical allyl isothiocyanate (AITC), an agonist of the nociceptive TRPA1 ion channel, and utilize AITC as an aversive stimulus in an associative learning paradigm. We find that larvae exposed to AITC in both a...

Persistence of Populations in Environments with an Interface

Creator:: Rekow, James A.
Abstract:: We model a fish population in a spatial region comprising a marine protected area and a fishing ground separated by an interface. The model assumes conservation of biomass density and takes the form of a reaction diffusion equation with a logistic reaction term. At the interface, in addition to continuity...

Navigating food and foes in the savanna : nutrition, infections and spatial ecology in African buffalo

Creator:: Combrink, Hendrik J.
Abstract:: The intricate relationship between wildlife health and the quality of their environment is well established, with technological advances increasing our understanding and aiding the unraveling of underlying mechanisms. Large herbivores require forage of sufficient quality to maintain their condition to reproduce and survive, all while warding off parasites and predators...

From Microbes to Megafauna: The Ecology of Gut Microbiomes in Wild Herbivores

Creator:: Couch, Claire E.
Abstract:: All mammals host communities of commensal microbes in and on their bodies. Recent technological advances, combined with experimental studies in laboratory animals, are beginning to reveal the ubiquitous links between the gut microbiome and host disease, metabolism, immunity, and numerous other host functions. A new challenge of microbiome research is...

Perceptions of a Changing Ocean: Resilience and Oregon's Commercial Fishing Community

Creator:: Haugen, Brianna I.
Abstract:: The complex challenges that Oregon’s commercial fishing community faces are mainly driven by four sources of change: climate change, change in management regulations, societal shifts, and market trends. Challenges include increasing competition for ocean use, management decisions that prioritize economic efficiency over community values, and an increasingly uncertain environment. The...

Combining Disparate Data Sources with Ecosystem and Integrated Models: Case Studies for Improving Management of Protected Species

Creator:: Chasco, Brandon E.
Abstract:: Globally, the number of threatened species is increasing and conserving them is a high priority to the scientific community. Assessing the status of these protected species is challenging due to missing, contested, and or contradictory data streams. Integrated models (IMs) provide a statistical framework for combining disparate data sources to...

Impacts of Policy and Environmental Change: Understanding Factors of Vulnerability and Resilience in the Face of Change in Oregon Fishing Communities

Creator:: Strawn, Astrea
Abstract:: Commercial fisheries are coupled human-natural systems that cross state borders and integrate private, public, academic sectors and interests. These systems integrate complicated relationships between coastal socioeconomics, resource management and environmental realms. Previous findings from West Coast-based studies have identified aging trends in commercial fisheries participation, commonly referred to as the...

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...

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...

Effects of Diversity on Emerging Infectious Diseases of Amphibians

Creator:: Snyder, Paul W.
Abstract:: Species declines and extinctions have been recorded across taxa as evidence of an ongoing global biodiversity crisis. Amphibians are at the forefront of these declines with nearly one third of amphibian species estimated to be at risk of extinction. While many factors contribute to population declines and extinctions, the role...
