  • The Role of Emerging Pathogens in Amphibian Population Declines : Experimental Evidence

    Creator:
    Hambalek, Natalie M.
    Abstract:
    Rapid rates of biodiversity loss have supported the notion that Earth is experiencing a sixth major extinction event. The causes of worldwide biodiversity loss are multifaceted and context dependent. One of the most prominent groups experiencing population declines and extinctions are amphibians. Several pathogens and their associated diseases are especially...

  • The effects of predation on anuran metamorphosis

    Creator:
    DeVito, Jill
    Abstract:
    Many organisms with complex life cycles undergo transition periods associated with increased vulnerability to predation. Several evolutionary adaptations have been proposed as antipredator defenses for organisms during risky transition periods. These include: shortening of the transition period, parental care, cryptic coloration, and synchrony of risky transitions with large numbers of...

  • Kin recognition in Townsend's chipmunks (Tamias townsendii)

    Creator:
    Fuller, Claire A.
    Abstract:
    Juvenile T. townsendii were tested at 55-62 days of age to determine whether 1) they could distinguish kin from non-kin and 2) whether this ability was based on familiarity or on genetic relatedness. Seventy-three pups were observed in 68 pairwise tests. The frequencies and durations of 8 behaviors as well...

  • Effects of pesticides on amphibians with special reference to the pyrethroidinsecticide, cypermethrin

    Creator:
    Biga, Lindsay M.
    Abstract:
    Pollution by pesticides is a ubiquitous concern for wildlife. The effects of pesticides are especially concerning in aquatic environments, which are particularly vulnerable as they have several exposure routes for the influx of chemicals. These effects are of particular concern as biodiversity loss reaches unprecedented rates. This includes recent declines...

  • 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...

  • The effects of an emerging pathogen on amphibian host behaviors and interactions

    Creator:
    Han, Barbara A.
    Abstract:
    Contemporary environmental change encompasses massive biodiversity loss and increasing numbers of emerging diseases worldwide. As part of a global biodiversity crisis, amphibians are disappearing at unprecedented rates. Batrachochytrium dendrobatidis is an emerging infectious pathogen prominently associated with many declines. Chapter 1 reviews the past decade of research on this system...

  • The effects of pathogens, UV-B radiation, and introduced species on amphibians in the Pacific Northwest

    Creator:
    Kiesecker, Joseph Michael
    Abstract:
    I examined two amphibian communities to assess factors that may impact amphibian biodiversity. The results suggest that the potential factors which influence the maintenance of amphibian biodiversity are multi-faceted and thus, attempts to understand these factors must reflect these complexities. I investigated factors that influenced the susceptibility of western toad...

  • The effects of multiple pathogens on amphibians in the Pacific Northwest

    Creator:
    Romansic, John M.
    Abstract:
    The earth is undergoing a “biodiversity crisis” characterized by loss of populations, species, genetic diversity, and ecosystem services. Part of this crisis consists of population declines, extinctions, and increased incidence of deformities in amphibians. It is unknown whether deformities contribute to these declines. Many cases of population declines in amphibians...

  • Host-pathogen dynamics in a changing environment : susceptibility of amphibians to an emerging infectious disease

    Creator:
    Searle, Catherine L.
    Abstract:
    Infectious diseases are a growing concern for both humans and wildlife. The negative effects of infectious disease have been exemplified by the recent global amphibian population declines associated with disease outbreaks. Although multiple pathogens and factors play a role in these declines, the aquatic fungal pathogen, Batrachochytrium dendrobatidis (Bd), has...
