  • Elevational differences in UV-B response by the long-toed salamander (Ambystoma macrodactylum)

    Creator:
    Thurman, Lindsey L.
    Abstract:
    Global amphibian declines have been attributed to numerous and often synergistic causes, such as invasive species, pathogens, and ultraviolet-B (UV-B) radiation. The effects of these stressors are context dependent and can vary with location, species, and populations. As sensitivity to UV-B has shown inconsistencies across amphibian taxa, it can be...

  • Invasive bullfrog use of novel ephemeral habitats in the Pacific Northwest

    Creator:
    Cook, Megan Tetsuko
    Abstract:
    Invasive species are a major threat to global biodiversity. Understanding the mechanisms underlying successful invasions is imperative for developing effective management strategies. Plasticity in physiological, morphological, and behavioral traits could be an indicator of invasion potential in non-native species. The invasive American bullfrog (Lithobates catesbeianus) has recently been observed breeding...

  • Patterns in responses of an amphibian assemblage to wetland restoration

    Creator:
    Rowe, Jennifer C.
    Abstract:
    Wetland restoration success in attaining wildlife conservation goals can be confounded by the presence of multiple biological invaders. Wetland management activities typically target invasive plants, but bottom-up responses of higher trophic levels in novel communities are difficult to predict. We surveyed plant and amphibian assemblages at 26 sites enrolled in...

  • Amphibian communities and climate change : Where ecological processes meet evolutionary interactions

    Creator:
    Thurman, Lindsey L.
    Abstract:
    Forecasts of the impacts of climate change have traditionally focused on individual species and their phenotypes, phenology, or distribution. However, shifts in species distributions and the resulting reorganization of community composition represent an important violation to the assumption of species acting in isolation. Whereas species may respond individualistically to climate...

  • Jumping in with Both Feet: Exploring Factors that Shape Juvenile Amphibian Movement

    Creator:
    Bredeweg, Evan M.
    Abstract:
    Investigation into how animals move within the landscape is important for both understanding of ecological processes and conservation management. Animal movement is important in shaping life history transitions, demographics, individual fitness, and species distributions. However, as landscapes become increasingly affected by human activities, movement becomes important as species navigate landscapes...

  • Microhabitat associations and behavioral dynamics of co-occurring native Pacifastacus leniusculus and invasive Procambarus clarkii crayfish in Oregon's southern Willamette Valley

    Creator:
    Hanshew, Brett Alan
    Abstract:
    Biological invasions are the second largest threat to biodiversity following habitat loss, and studying invasions has been a focus of ecological the past two decades. Despite the intense research, many basic questions remain empirically unanswered, particularly in the realm of behavior. The purpose of this research was to explore the...

  • Agricultural impacts on amphibian survival, growth, and distributions

    Creator:
    Baker, Nick J.
    Abstract:
    The potential impact of chemical contaminants and conservation practices on amphibians in agricultural landscapes is a key research topic globally. Amphibians represent a common group in many freshwater systems and are currently experiencing worldwide population declines. Global amphibian declines may be attributed to a number of causes, including habitat loss,...
