  • 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,...

  • Advances in Camelid Theriogenology

    Creator:
    McAllister, Anna
    Abstract:
    Reproductive physiology of South American camelids is unique, especially in comparison to other domestic animals. For example, mating occurs in a recumbent position over a period of approximately 30 minutes. Males are dribble ejaculators, and the camelid ejaculate is highly viscous making it nearly impossible to work with in vitro....

  • Cellular Recognition, Division, and Proliferation in the Cnidarian-Dinoflagellate Symbiosis

    Creator:
    Tivey, Trevor R.
    Abstract:
    Cnidarians and their symbiotic dinoflagellates form a productive mutualism that shapes marine environments. In this symbiosis, dinoflagellate species from the family Symbiodiniacea reside within cnidarian host gastrodermal cells and provide the host with photosynthetically fixed carbon in exchange for host metabolites. This nutritional exchange allows both partners to thrive in...

  • 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,...

  • Explorations Into Who is Doing Freshwater Science and How We are Altering Waterscapes

    Creator:
    Abernethy, Erin F.
    Abstract:
    The United States of America and the world are faced with three massive intertwining challenges at this time: COVID-19, racial inequity, and climate change. As a species, humans must come together and collectively address these challenges to preserve our humanity and make our world a more just and livable place...

  • The Influence of Prey Predictability on the Foraging Behavior and Movement of Intertidal Predators

    Creator:
    Hennessey, Shannon M.
    Abstract:
    Fluctuations and spatial heterogeneity of habitat and resources is thought to underlie niche variation in animal populations, with intraspecific differences serving to produce or maintain population-, community-, or ecosystem-level patterns. Individual diet variation, defined as individual variation in food resource use within a population that is consistent over time, is...

  • Drivers of Kelp Forest Responses to Global Change: From Populations to Policies

    Creator:
    Hamilton, Sara L.
    Abstract:
    Kelps are large brown algae in the order Laminariales and are foundation species that form the basis of kelp forests. Present across a quarter of the world’s coastlines, kelp forests provide diverse services to coastal communities, as habitat for commercially and culturally important species, as a food source for humans...
