  • In search of ecological advantages : Mycorrhizal facilitation of big huckleberry Vaccinium membranaceum (Doug.)

    Creator:
    Stocking, Peter
    Abstract:
    Temperate evergreen forests of the Pacific Northwest support big huckleberries (Vaccinium membranaceum) despite their nutrient impoverished soils. Acquisition of nitrogen and phosphorous are the major nutrients limiting V. membranaceum. The plant’s access to these resources is linked to their mycorrhizal symbiosis. To learn more about the symbionts of eriaceous plants...

  • The Distribution and Abundance of a Non-native Eelgrass, Zostera japonica, in Oregon Estuaries

    Creator:
    Dudoit, Chana Makale’a
    Abstract:
    Biological introductions may considerably alter the composition and community dynamics of invaded areas thereby changing many ecosystem processes including productivity, decomposition, nutrient cycling and hydrology. The effects on native species may be obscured by a lack of information on distribution and abundance patterns. The Japanese eelgrass, Zostera japonica, was introduced...

  • Patterns of age and growth in young-of-year rockfish, sebastes spp., along the Oregon coast

    Creator:
    Young, Thomas
    Abstract:
    Rockfish of the genus Sebastes are important components of Oregon reef communities. I examined patterns of age and growth in young-of-year rockfish across two nested spatial scales – local and regional – along the Oregon coast. Using otolith microstructural examination, I examined the relative importance of local versus regional factors...

  • Cool hideaways: use of temperature refuges by juvenile coho salmon in the West Fork Smith River

    Creator:
    Raskauskas, Nancy
    Abstract:
    The West Fork Smith River, a 69 km2 watershed in the Coast Range of Oregon, is prone to short periods of very high water temperature in mid-summer due to a combination of human and natural influences. In the summers of 2003 and 2004 more than 400 juvenile coho salmon regularly...

  • 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...

  • Perceptual thresholds for foot slipping in animated characters

    Creator:
    Strawn, Jordan J.
    Abstract:
    The computer game industry continues to progress toward realistic-looking character motion. However, even in state-of-the-art games, the use of motion capture data in character animation may result in errors such as “foot slipping,” where the feet do not match up with the floor properly during translation. Various algorithms have been...

  • A critical analysis of the globalization of English in the U.S. and abroad

    Creator:
    De Lora, Emily
    Abstract:
    Although thousands of volunteers from the United States go abroad each year to teach English, many are unprepared for their experiences. Undergraduate students teaching in a foreign country seem to lack training in educational methodology or foreign relations that would prepare them for teaching and living abroad. This project was...

  • Entrapment of Micro-Algae in Modified Alginate Beads for Oxygen and Nutrient Source

    Creator:
    Hughson, Jason D.
    Abstract:
    Presented here is an investigation and comparison of two entrapment methods of algae. Conventional calcium alginate bead entrapment is compared to a recently described modified bead entrapment method, utilizing poly(ethylene glycol) and calcium alginate, which results in void or capillary formation within the beads. It is shown that algal growth...

  • Militant and nonviolent social movements

    Robinson, Blake
    Abstract:
    While much has been written about why people join social movements in general, little has been written about why people specifically join either militant or nonviolent social movements. Using the Black Panther Party as an example of a militant social movement and the mainstream Civil Rights Movement as an example...

  • Beyond free will: an empirical case for a capacity model of human agency

    Creator:
    Helzer, Erik G.
    Abstract:
    Although the question of free will has persisted throughout the history of philosophy as an important metaphysical consideration, rarely does the inquiry include empirical evidence from other disciplines concerned with human behavior. In this interdisciplinary paper, I combine the wisdom of psychologists, metaphysicians, and philosophers of science to comment on...
