  • Habitat Use of Female Columbian Black-tailed Deer in Western Oregon

    Creator:
    Schrautemeier, Timothy J.
    Abstract:
    Columbian black-tailed deer (Odocoileus hemionus columbianus) are important economically, ecologically, and culturally as an indigenous species in western Oregon. Oregon Department of Fish and Wildlife (ODFW) observed declines in black-tailed deer populations since the late 1980’s and attributes these declines to reduction in quality and availability of habitat, following the...

  • Comparative epidemiology of Phytophthora diseases of Rhododendron

    Creator:
    Taylor, Clare Rebecca
    Abstract:
    Rhododendron species are host to many Phytophthora species and are an important crop in the nursery industry. The foliar epidemiology of twelve Phytophthora diseases on Rhododendron was studied in field and growth chamber experiments on two Rhododendron cultivars. The relative aggressiveness of Phytophthora spp. was assessed using disease incidence, severity,...

  • Effect of plant date on subsequent seedling field performance

    Creator:
    Taylor, Michael Monroe
    Abstract:
    Douglas-fir (Psudotsuga menziesii (Mirb.) Franco) seedlings were outplanted on eight dates (every three weeks from mid-August 2005 through mid-January 2006). On each plant date, seedlings from a conventional dormancy (CONV) induction treatment, including moisture and nutrient stress, and a shortened daylength (SD) treatment were outplanted on three western Oregon sites...

  • A Political Ecology Lens for the Nutrition Transition in Rural, Kedougou, Senegal

    Creator:
    Lucey, Taylor K.
    Abstract:
    The nutrition transition is a global phenomenon in which populations move from low socioeconomic status (SES) to high SES and from high physical activity to low physical activity. Rising rates of urbanization and non-communicable diseases in West Africa may indicate an advanced phase of the nutrition transition; however, through a...

  • Stable Isotope Constraints on Carbon Dioxide and Nitrous Oxide Variations at the Onset of the Last Glacial Period: New Ice Cores from Taylor Glacier, Antarctica

    Creator:
    Menking, James A.
    Abstract:
    New ice cores retrieved from the Taylor Glacier (Antarctica) blue ice area contain ice and air spanning the Marine Isotope Stage (MIS) 5/4 transition, a period of global cooling and ice sheet expansion. Chronologies were determined for the ice and air bubbles in the new ice cores by visually matching...

  • Natural enemies of native bumble bees (Hymenoptera: Apidae) in western Oregon

    Creator:
    Maxfield-Taylor, Sarah A.
    Abstract:
    Bumble bees (Hymenoptera: Apidae) are important native pollinators in wild and agricultural systems, and are one of the few groups of native bees commercially bred for use in the pollination of a range of crops. In recent years, declines in bumble bees have been reported globally. One factor implicated in...

  • Onset of symbiosis in a cnidarian-dinoflagellate association

    Creator:
    deBoer, Melissa L.
    Abstract:
    Scleractinian corals, like many other cnidarians, engage in intracellular symbiosis with dinoflagellates belonging to the genus Symbiodinium. This association makes invaluable structural and energetic contributions to the marine environment and to the coral reef ecosystem in particular. While many aspects of the cnidarian-dinoflagellate relationship have been well studied, nothing is...

  • Protein Disorder in the Evolution of Dynein Regulation

    Creator:
    Jie, Jing
    Abstract:
    Intrinsically disordered proteins (IDP) are a class of proteins that lack a three-dimensional structure and their prevalence and diverse functions in the cell have only been discovered relatively recently. The intermediate chain (IC) subunit of the microtubule motor protein complex dynein contains an N-terminal disordered region, N-IC, which is central...

  • The ecology of parasite interactions within Chinook salmon

    Creator:
    Hurst, Charlene N.
    Abstract:
    The within-host interactions that can occur as a result of mixed infections in wildlife likely influence the outcome of an infection. We investigated the infection frequency and outcome as well as the potential mechanisms regulating mixed infections with two Ceratonova shasta genotypes within the Chinook salmon host. Previous research in...
