  • Effects of environmental stress on intertidal mussel reproduction

    Creator:
    Petes, Laura E.
    Abstract:
    Environmental stress can negatively affect the ability of organisms to reproduce. Energetic trade-offs exist in all organisms, and under stress, energy may be allocated away from reproduction and towards physiological defense and repair mechanisms. The rocky intertidal environment is ideal for investigating the influence of environmental stress, as organisms are...

  • Three-dimensional motion of the center of mass and energetic cost across a variety of walking speeds : a comparison between adults with and without Down syndrome

    Creator:
    Agiovlasitis, Stamatis
    Abstract:
    It has been previously suggested that the walking pattern of individuals with Down syndrome is inefficient. This is thought to result from increased instability, particularly in the medio-lateral direction, due to the characteristic joint laxity and muscle hypotonia of individuals with DS. Therefore, this work was an attempt to gain...

  • Indirect effects of fishing on predators and their prey

    Creator:
    Stallings, Christopher Derek
    Abstract:
    Predators are fundamentally important for regulating and driving prey population dynamics as well as structuring ecological communities. Over-exploitation of marine resources has caused dramatic depletions of predatory fish species and shifts in marine community composition, with attendant declines in productivity and diversity of marine ecosystems. Despite the important ramifications of...

  • The marine geomorphology of American Samoa : shapes and distributions of deep sea volcanics

    Creator:
    Roberts, Jed T.
    Abstract:
    The geologic processes at work in American Samoa have long been a point of scientific debate. Of its numerous volcanic formations, few breach sea level, leaving an enormous proportion of their mass unavailable to traditional observation. This study aims to describe the deep sea geomorphology of American Samoa through compilation,...

  • 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...

  • Fire severity and vegetation response to fire in riparian areas of the Biscuit and B&B Complex Fires, Oregon

    Creator:
    Halofsky, Jessica E.
    Abstract:
    Fire is the dominant disturbance process in western U.S. forests, and although effects of fire in upland forests are relatively well-studied, there is little information about fire effects on riparian forests, critical areas of the landscape for both habitat and water quality. This dissertation examines different aspects of fire effects...

  • Advancing marine reserve science : from field experiments to marine conservation planning tools

    Creator:
    Leslie, Heather M.
    Abstract:
    This dissertation focuses on science relevant to the design and implementation of marine reserves. The chapters explore a range of topics related to among-site variation in population, community, and ecosystem dynamics. My results demonstrate the value and feasibility of integrating this knowledge into more comprehensive conservation and management approaches. While...

  • Ultraviolet radiation as an environmental stressor of amphibians

    Creator:
    Bancroft, Betsy A.
    Abstract:
    My thesis explored the effects of and potential mediating mechanisms for an important environmental stressor, ultraviolet-B (UVB) radiation. UVB radiation has negative effects on organisms in both terrestrial and aquatic systems. I used meta-analysis to quantify the effects of UVB radiation on a diversity of aquatic organisms (Chapter 2). UVB...
