  • Physiological and organism level endpoints in the beetle pterostichus oblongopunctatus (Coleoptera: Carabidae), inhabiting a gradient of heavy metal pollution

    Creator:
    Stone, David
    Abstract:
    Pollutant body burdens, ability to tolerate supplementary stressors, and biomarkers of physiological stress were investigated in the ground beetle, Pterostichus oblongopunctatus (Coleoptera: Carabidae), inhabiting a gradient of heavy metal contamination in Poland. The central question was to determine if beetles inhabiting polluted habitats incurred costs compared with beetles in less...

  • Genetic Structure in Populations of the Douglas-fir Swiss Needle Cast Fungus Nothophaeocryptopus gaeumannii

    Creator:
    Bennett, Patrick I.
    Abstract:
    The fungus Nothophaeocryptopus gaeumannii is the causative agent of Swiss needle cast (SNC), a foliar disease of Douglas-fir. Disease is characterized by premature loss of foliage and reduced growth resulting from the inhibition of photosynthesis due to the occlusion of stomata by the ascocarps of N. gaeumannii. Although the disease...

  • Identification of optimal broodstock for Pacific Northwest oysters

    Creator:
    Stick, David A.
    Abstract:
    The United States Pacific Northwest is well known for its shellfish farming. Historically, commercial harvests were dominated by the native Olympia oyster, Ostrea lurida, but over-exploitation, habitat degradation, and competition and predation by non-native species has drastically depleted their densities and extirpated many local populations. As a result, shellfish aquaculture...

  • Human Exposure to PAHs in Air, Water, and Crayfish

    Creator:
    Paulik, L. Blair
    Abstract:
    There are many links between exposure to environmental pollution and risks to human health. While advances in the fields of toxicology, exposure science, and environmental chemistry have shown light on many of these links, many more research challenges remain. One major challenge is how to accurately characterize the toxicity of...

  • Essays on behavioral economics

    Creator:
    Cao, Zheng
    Abstract:
    This dissertation consists of two essays that address behavioral economics issues. In first chapter we analyze the effects of psychological pressure on performance using National Basketball Association (NBA) free throw data from the 2002-2003 through 2009-2010 seasons. We find evidence that players choke under pressure – they shoot on average...

  • A design framework for identifying automation opportunities

    Creator:
    Nagel, Robert Lewis, 1982-
    Abstract:
    Since the Industrial Revolution, automated systems have increasingly become a part of everyday life. Automated systems range in scale and scope from simple assists to complete robotic replacements. Inexpensive integrated circuits, sensors and microprocessors have allowed automated systems to become smaller, cheaper and more prevalent. Identifying appropriate opportunities for automation,...

  • Development, evaluation and application of a mixed-family selective breeding method for the Pacific oyster (Crassostrea gigas)

    Creator:
    Matson, Sean Erik
    Abstract:
    This dissertation develops mixed family selection for Pacific oysters using marker-based pedigree reconstruction. It focuses on improving the efficiency of parentage assignment, determining the optimum life stage to mix oyster families for rearing and selection, comparing mixed-family and separate-family selective breeding in the field, and applying the mixed method to...

    Creator:
    Bair, Zolton J.
    Abstract:
    Whitebark pine (Pinus albicaulis) is an iconic North American high-elevation tree species currently threatened by climate change, mountain pine beetle, and white pine blister rust (WPBR), a lethal disease caused by the non-native fungal pathogen Cronartium ribicola. In collaboration with the USDA Forest Service Dorena Genetic Resource Center, germplasm was...

  • Characterization of Fungal Communities in Selected Wood Species by Field Exposure Tests

    Creator:
    Torres-Andrade, Paola A.
    Abstract:
    Fungi are the primary biological agents of wood deterioration and cause major economic losses of wood products globally. Wood in outdoor applications tends to remain wet for extended time periods, making it susceptible to fungal attack. Understanding the factors involved in fungal colonization of wood is important for developing improved...
