  • UVB Radiation Affects the Quality of the Female Sexual Attractiveness Pheromone of the Red-Sided Garter Snake

    Creator:
    Vigeland, Anna E.
    Abstract:
    In this study, pheromone and skin lipid samples collected from red-sided garter snakes (Thamnophis sirtalis parietalis) were exposed directly to either full-spectrum light or full-spectrum plus UVB light. In addition, female and male snakes were exposed to daily doses of either full-spectrum or full-spectrum and UVB light, after which the...

    Abstract:
    Data from the southern Cascade Mountains of Oregon has been collected for application in computer analysis of snowfields. Vegetation type, canopy cover, slope, aspect, insolation, and snowfield ground truth delineation are given consideration. In addition, a procedure for transferral of data onto Landsat imagery was derived.

  • Inter-relationships of vegetation, hydrology and micro-climate in a young, Douglas-fir forest

    Creator:
    Barnard, Holly Rene
    Abstract:
    The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...

  • Involvement of PP6 in Dephosphorylation of Bcl11b, a Tumor Suppressor Transcription Factor

    Creator:
    Parker, Chelsea R.
    Abstract:
    The purpose of this honors thesis research project is to investigate the molecular causes of childhood and infant T-cell acute lymphoblastic leukemias. T-cells are the work horses of the immune system, and like any organ, must develop properly to be fully functional. Improper development of thymocytes into T-cells can lead...

  • Activation, modification and suppression of sex pheromone production in garter snakes

    Creator:
    Parker, M. Rockwell
    Abstract:
    Vertebrates communicate with one another and coordinate intraspecific reproduction by using a variety of sexually dimorphic signals, such as plumage, ornaments, sounds, and/or scents. These sexual dimorphisms are maintained by physiological factors, typically sex-specific hormones (though see Chapter 3 for an exception). The purpose of the research in this dissertation...

  • The effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin on T cell activation

    Creator:
    Shepherd, David M.
    Abstract:
    The immune system has been identified as a very sensitive target for the toxic effects of 2,3,7,S-tetrachlorodibenzo-p-dioxin (TCDD). Exposure to TCDD has been shown to disrupt the generation of both cell-mediated and humoral T cell-dependent immunity in laboratory animals; however, the mechanism remains unknown. In this dissertation, the hypothesis is...

  • Sexual dimorphism and seasonal changes in the Harderian gland of the red-sided garter snake, Thamnophis sirtalis parietalis

    Creator:
    Erickson, Sten M.
    Abstract:
    The Harderian gland (HG) of the red-sided garter snake, Thamnophis sirtalis parietalis, is a secretory structure that plays a role in the vomeronasal system by solubilizing semiochemicals such as prey chemoattractants and the female sexual attractiveness pheromone. The HG produces secretions containing pheromone-binding proteins that form a complex with pheromone...

  • Effects of Forest Harvest, Floods, and Wildfire on Bedload Export from Headwater Catchments in the H.J. Andrews Experimental Forest, 1957 – 2022

    Creator:
    Wright, Charles M.
    Abstract:
    This study examined how annual bedload export volume and bedload characteristics were related to disturbances including logging, floods, debris slides, and wildfires over 48 to 65-year periods in small, steep catchments in conifer forests of the western Cascade Range, Oregon. Bedload – the material rolling, sliding, or saltating along the...

    Parker, Andrew M. and Weller, Joshua A.
    Abstract:
    Decision-making competence reflects individual differences in the susceptibility to committing decision-making errors, measured using tasks common from behavioral decision research (e.g., framing effects, under/overconfidence, following decision rules). Prior research demonstrates that those with higher decision-making competence report lower incidence of health-risking and antisocial behaviors, but there has been less focus...
