  • The relationship between income and food insecurity : the role of social support in rural and urban Oregonians

    Creator:
    De Marco, Molly M.
    Abstract:
    Millions of U.S. households experienced hunger in 2005 and millions more experienced food insecurity. Previous research indicates that low-wage work and little social support contribute to food insecurity. Research also suggests that individuals cope by finding alternate food sources and drawing on social support. Further, researchers have found that rural...

  • Glyphosate-resistance in Italian ryegrass (Lolium multiflorum): evaluation and investigation of the mechanisms of resistance

    Creator:
    Perez-Jones, Alejandro
    Abstract:
    A suspected glyphosate-resistant Italian ryegrass (Lolium multiflorum) (OR) population was collected from a filbert (Corylus avellana L.) orchard near Portland, OR. Based on the dose-response experiments conducted in the greenhouse, it was found that the suspected glyphosate-resistant population was approximately fivefold more resistant to glyphosate than the susceptible (S) population....

  • Effects of environmental stress on intertidal mussel reproduction

    Creator:
    Petes, Laura E.
    Abstract:
    Environmental stress can negatively affect the ability of organisms to reproduce. Energetic trade-offs exist in all organisms, and under stress, energy may be allocated away from reproduction and towards physiological defense and repair mechanisms. The rocky intertidal environment is ideal for investigating the influence of environmental stress, as organisms are...

  • Advances in expression of heterologous protein products by Streptococcus gordonii

    Creator:
    Warren, Travis Kent
    Abstract:
    Streptococcus gordonii is a bacterial species that naturally colonizes the oral cavity of most healthy humans. It resides in the mouth as an adherent to dental surfaces and, with few exceptions, does not cause disease in individuals it inhabits. It possesses qualities that encourage its use as a vector to...

  • Tidal influence on downstream fining in gravel-bed rivers

    Creator:
    Coles, Derron Rafiq
    Abstract:
    This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

  • Community gradients of Arctic macrolichens in relation to succession, grazing and the environment

    Creator:
    Holt, Emily A.
    Abstract:
    The purpose of this dissertation was to define macrolichen community gradients in relation to succession, grazing and the environment. First, species scores indicating when macrolichen species appeared following disturbance were derived from the literature. Weighted averaging of these data with a community matrix created a successional score for each sample...

  • Using rootstocks to manipulate vine physiological performance and mediate changes in fruit and wine composition

    Creator:
    Sampaio, Tiago Luís Barros
    Abstract:
    A rootstock trial was established in 1997 at the OSU Woodhall vineyard, located in the Southern Willamette Valley, which included two experiments. The first experiment was a factorial of four varieties grafted on to 9 rootstocks, and also as ungrafted vines (a split-plot design). The second experiment was a randomized...

  • Quantitative resistance to Puccinia striiformis f. sp. hordei in barley near-isogenic (BISON) lines

    Creator:
    Richardson, Kelley L.
    Abstract:
    Quantitative resistance (QR) to disease is usually more durable than qualitative resistance, but its genetic basis is not well understood. We used the barley/barley stripe rust pathosystem as a model for the characterization of the QR phenotype and associated genomic regions. As an intermediate step in the preparation of near-isogenic...

  • The aging endoplasmic reticulum

    Creator:
    Dixon, Brian M.
    Abstract:
    Hallmarks of aging include the accumulation of aberrant proteins and a lower resistance to stresses. Because the endoplasmic reticulum (ER) functions to fold proteins and possesses unique stress sensing pathways, the central hypothesis of this dissertation is that the ER is a target of cellular aging and significantly underlies these...

    Fluharty, Suzanne M.
    Abstract:
    This dissertation looks at one landscape component of the Coquille Indian Tribe's ancestral lands in order to understand the place meaning created and assigned to Euphoria Ridge, Oregon. I focus on three cultural overlays across time that together with the unique biophysical components, generate an importance for the locale to...
