  • 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...

  • The Behavioral Responses of Western Toad (Anaxyrus boreas) Larvae to Simultaneous Stressors

    Creator:
    Reynolds, Emily R.
    Abstract:
    Animals can be naturally exposed simultaneously to multiple stressors. These include habitat changes, contaminants, diseases, invasive species, parasitism, and predation. Exposure to various combinations of biotic and abiotic stressors may induce behavioral changes that affect the way an individual interacts within its environment.Like other groups of organisms, amphibians are exposed...

  • 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...

  • Individual Host to Population Scale Dynamics of Parasite Assemblages in African Buffalo of Kruger National Park, South Africa

    Creator:
    Glidden, Caroline K.
    Abstract:
    The last century has experienced a marked increase in emerging infectious disease (EID, hereafter) – jeopardizing human, domestic animal, and wildlife health. EIDs are commonly associated with spillover from one host species into a novel host species, with many destructive diseases, for both livestock and wildlife, emerging at the wildlife-livestock...

  • 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...

  • 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...

  • Orbiting the Genus of False Units: Dynamics of Phage Genomes and Nematode Microbiomes Associated with Pseudomonas spp.

    Creator:
    Ha, Anh D.
    Abstract:
    Pseudomonas is a diverse, ubiquitous, and widely studied genus of bacteria. As Pseudomonas species occupy a wide range of niches in the ecosystem, they have made remarkable biological impacts. Better understanding of Pseudomonas biology, genetic diversity, and functional interactions with other organisms and the environment will provide valuable insights into...

  • The Role of Algal Cellular Physiology on the Onset and Maintenance of a Model Cnidarian-Algal Symbiosis

    Creator:
    Maruyama, Shumpei
    Abstract:
    Coral reefs form vast ecosystems in tropical oceans that are hotspots for biodiversity and are economically valuable. The ecological success of coral reefs is made possible by the symbiotic relationship between corals and dinoflagellate algae from the family Symbiodiniaceae. In this symbiosis, the algae are found within host gastrodermal cells...

  • Life in a Rapidly Changing Environment: The Thermal Biology of the Red-sided Garter Snake (Thamnophis sirtalis parietalis)

    Creator:
    Hubert, David L.
    Abstract:
    At a time when environmental conditions are rapidly changing, understanding how thermal extremes impact wildlife is imperative to fully understanding the consequences of climate change in natural ecosystems. While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...

  • Emergent Properties of Animal Social Networks: Five Stories in Five Systems

    Creator:
    Devan-Song, E. Anne
    Abstract:
    Animals aggregate and interact in nonuniform and nonrandom patterns, which lead to group level characteristics that have important evolutionary and ecological consequences. Network analysis provides a useful conceptual framework for linking animal interactions at all scales from dyads to communities, to populations and ecosystems. Despite exciting theoretical and applied advances...
