  • Nearshore wave predictions along the Oregon and southwest Washington coast

    Creator:
    García-Medina, Gabriel
    Abstract:
    This thesis contains a manuscript describing the implementation of a high resolution wave forecasting model for the coasts of Washington and Oregon. The purpose of this project was to advance the wave predictive capabilities of the states of Oregon and the southwest part of Washington by including the effects of...

  • 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...

  • The Effects of Road Noise on Pacific Chorus Frog Communication

    Creator:
    Nelson, Danielle V.
    Abstract:
    Amphibians are experiencing global population declines and are one of the most threatened groups of vertebrates. This can be attributed to multiple environmental stressors such as habitat loss, disease, invasive species, and climate change. For vocal amphibian species, loss of acoustic habitat due to anthropogenic noise may be yet another...

  • Post-breeding habitat selection by songbirds in the headwaters of the Trask River, northwestern Oregon

    Creator:
    Jenkins, Stephanie R.
    Abstract:
    Little is known on the importance of riparian areas to birds near small headwater streams in mesic forests. Progress towards understanding limiting factors that affect bird populations has been difficult because of lack of information beyond the breeding period. I compared bird assemblages between headwater riparian and upland areas throughout...

  • The feasibility of applying air photo interpretation to the locating, analyzing and development of wind power sites

    Creator:
    Maule, Peter Anthony
    Abstract:
    If wind power is to become a viable energy alternative, a rapid and reliable cost effective methodology must be established, whereby large areas can be surveyed for windy sites and those sites can be evaluated. Based primarily on locating wind deformed vegetation, this paper establishes the feasibility of using air...

  • Environmental contaminants and breeding biology of great blue herons in the Columbia River Basin

    Creator:
    Thomas, Carmen M.
    Abstract:
    Great blue heron (Ardea herodias) eggs and prey items were collected from six colonies on the Columbia and Willamette rivers and Puget Sound during 1994-95. Contaminant concentrations, reproductive success, and biomagnification factors (BMFs) were determined and effects of residue levels were measured by H4IIE rat hepatoma and ethoxyresorufin-O-dealkylase (EROD) bioassays....

  • Spatial and Temporal Dynamics of Broad-scale Predictive Models : Influences of Scale

    Creator:
    Hooper, Samuel
    Abstract:
    Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...

  • Climate warming effects on the life cycle of the parasite Ceratomyxa shasta in salmon of the Pacific Northwest

    Creator:
    Chiaramonte, Luciano V.
    Abstract:
    Aquatic ecosystems continue to be increasingly affected by climate warming. For salmonids in the Pacific Northwest of North America, increasing temperatures pose tighter thermal constraints on their habitat use as well as aspects of their individual performance, such as disease resistance. This thesis examines the effect of temperature on the...

  • Demography and habitat selection of northern spotted owls in post-fire landscapes of southwestern Oregon

    Creator:
    Clark, Darren A.
    Abstract:
    Several large wildfires in southwestern Oregon during the summers of 2001 and 2002 provided the opportunity to investigate the impacts of wildfire on northern spotted owls (Strix occidentalis caurina). I used radio-telemetry and demographic surveys to describe demographic performance and habitat selection of spotted owls in the areas burned by...

  • Uncovering the mechanism of IL-4-mediated T cell survival

    Creator:
    Moscibrocki, Cathleen M.
    Abstract:
    Although IL-4 is a well-characterized multi-functional cytokine, its role as a survival factor in T cells is not completely understood. In an attempt to uncover IL-4-mediated survival, we studied caspase activation in primary mouse T lymphocytes undergoing death by neglect, activation-induced or steroid-induced cell death. Here, we identify the executioner...
