  • Improving Pacific oyster (Crassostrea gigas) production through selective breeding

    Creator:
    Evans, Sanford, 1968-
    Abstract:
    Shellfish growers have expressed interest in developing high-yielding oyster strains through selective breeding. This dissertation has three objectives to help determine the effects of genetic and environmental variation on production traits (body weight, survival, and yield) of Pacific oysters grown in the Pacific Northwest. Objective 1: Determine if relative family...

  • Fraternity men's diversity experiences and degree of gender role conflict

    Creator:
    Schalewski, Lucas L.
    Abstract:
    Gender role conflict has been found to be a psychological condition that produces negative outcomes for men as they negotiate the tensions between who they truly are and who they feel they must be based on social expectations (O'Neil, Helms, Gable, David, & Wrightsman, 1986). Recent studies on college men's...

  • In Defense of the "Ringding Mukta" : The Later Work of J.D. Salinger

    Creator:
    Herb, Danielle Kristine
    Abstract:
    My thesis explores the later work of author J.D. Salinger, including two narratives featured in Nine Stories, "A Perfect Day for Bananafish," and "Teddy," and Franny and Zooey, "Raise High the Roof Beam, Carpenters," and "Seymour: an Introduction." Through my analysis I argue that the religious nature of Salinger's fiction...

  • Bridging environmental physiology and community ecology : temperature effects at the community level

    Creator:
    Iles, Alison C.
    Abstract:
    Most climate change predictions focus on the response of individual species to changing local conditions and ignore species interactions, largely due to the lack of a sound theoretical foundation for how interactions are expected to change with climate and how to incorporate them into climate change models. Much of the...

  • Belowground carbon storage and soil organic matter quality following fertilizer and herbicide applications in ponderosa pine plantations along a site-quality gradient in northern California

    Creator:
    McFarlane, Karis J., 1979-
    Abstract:
    Belowground carbon (C) storage and quality of soil organic matter (SOM) in forest soils have implications for sustainable forest management and C sequestration, but how these pools change in response to management is poorly understood. I investigated whether fertilization and competing vegetation control, applied alone or in combination early in...

  • Estimating the Influence of the Urban Heat Island Effect on Housing Prices

    Creator:
    Hossain, Lima
    Abstract:
    Using summertime housing transactions data of 3,309 parcels from multiple years in Eugene-Springfield, OR, we present a hedonic price model to estimate the influence of the urban heat island (UHI) effect on housing prices in this metropolitan area. By taking advantage of the inherent random nature of summertime weather observations,...

  • Natural Products Discovery from Unique Microbial Habitats

    Creator:
    Gallegos, David A.
    Abstract:
    Marine natural products possess an abundance of diverse chemical scaffolds with unique biological activities. By targeting unusual or unique microbial environments within varying marine ecologies we can continue to discover novel chemistry with potentially new molecular targets. The research presented here is focused on exploring unusual chemical ecologies and the...

    Abstract:
    Street children are a significant presence in Hue, Viet Nam's tourist center, where they eat, sleep, work, and play. Utilizing ethnographic methods, this study examines how tourism impacts the lives of street children involved in the industry. The street children have generally been compelled to leave home because of adverse...

  • Drivers of plant community dynamics in sagebrush steppe ecosystems : cattle grazing, heat and water stress

    Creator:
    Reisner, Michael D.
    Abstract:
    Sagebrush steppe ecosystems are one of the most widespread but endangered ecosystems in North America. A diverse array of human-related stressors has gradually compromised these ecosystems' resilience to disturbance and invasion by Bromus tectorum (cheatgrass). The role of the foundational shrub Artemisia as a driver of herbaceous community structure and...

  • Limitations to Seedling Regeneration on Tropical Forest Restoration Plantations in Northern Thailand

    Creator:
    Sangsupan, Hathai A.
    Abstract:
    This dissertation investigated potential ecological limitations to seedling regeneration in young, seasonally dry, evergreen forest restoration plantations in northern Thailand. We explored whether recruitment of colonizing tree species in the restoration plantations can be attributed to seed dispersal mode (i.e. abiotic or animal dispersal) and seed size. We did this...
