  • Ontogenetic Shifts in Disease Response in Native and Invasive Anuran Species

    Creator:
    Urbina Gonzalez, Jenny Cecilia
    Abstract:
    This dissertation presents a different approach to understanding how amphibians are responding to disease through ontogeny. Although numerous efforts have been conducted to understand host responses to the fungus Batrachochytrium dendrobatidis (Bd), studies have been restricted to distinct developmental stages. This dissertation provides information on host response to Bd across...

  • Disentangling the Biotic and Abiotic Drivers of the Amphibian Disease Chytridiomycosis

    Creator:
    Bradley, Paul W.
    Abstract:
    The ongoing worldwide loss of biodiversity has been described as a "biodiversity crisis," "the Anthropocene defaunation," and alternatively "an extinction spasm." More recently, many scientists have come to the conclusion that we are witnesses to Earth's sixth major mass extinction event, which has the potential to fundamentally alter basic ecological...

  • The ecology of parasite interactions within Chinook salmon

    Creator:
    Hurst, Charlene N.
    Abstract:
    The within-host interactions that can occur as a result of mixed infections in wildlife likely influence the outcome of an infection. We investigated the infection frequency and outcome as well as the potential mechanisms regulating mixed infections with two Ceratonova shasta genotypes within the Chinook salmon host. Previous research in...

  • All hosts are not created equal : variation in amphibian responses to an emerging fungal pathogen and why it matters

    Creator:
    Gervasi, Stephanie S.
    Abstract:
    Emerging infectious diseases are increasing globally and are a threat to human, wildlife, and ecosystem health. The emerging fungal pathogen, Batrachochytrium dendrobatidis (Bd), or amphibian chytrid fungus, is associated with worldwide amphibian population declines and extinctions. Bd has been found on every continent where amphibians exist and has been documented...
