  • Implementation of Distributed Localized Communications

    Creator:
    Snyder, Thomas
    Abstract:
    Artificial collectives are useful for accomplishing tasks that require teamwork from multiple simple robots. Multiple robot and collective testbeds have been developed, yet none stay committed to leverage the local interactions, group size, and imperfect information assumptions that strengthen biological collectives. A review of the collective and multiple robot literature,...

  • Specificity of quantitatively expressed host resistance to Mycosphaerella graminicola

    Creator:
    Krenz, Jennifer E.
    Abstract:
    The specificity of quantitative host resistance to plant disease has long been a controversial issue. We examined interactions between wheat (Triticum aestivum) and Mycosphaerella graminicola, causal agent of Septoria tritici blotch, to determine whether specific interactions occur between host and pathogen genotypes that could be involved in eroding quantitatively expressed...

  • Relative heat sensitivities and the potential for soil solarization to remediate nursery beds infested with Phytophthora spp.

    Creator:
    Weidman, Clara Suzanne
    Abstract:
    Infestations of container nursery beds by Phytophthora spp. can be persistent and costly. One method of disinfestation that does not require the use of chemicals is soil solarization, which captures energy from the sun to heat soil and thermally inactivate target pathogens. In laboratory temperature gradient experiments, I investigated the...

  • The effects of Phytophthora ramorum stem inoculation on aspects of tanoak physiology and xylem function in saplings and seedlings

    Creator:
    Stamm, Elizabeth A.
    Abstract:
    Phytophthora ramorum, an oomycete plant pathogen, is the causal agent of sudden oak death, a serious disease of Fagaceous trees in California and Oregon over the last decade. Tanoak (Notholithocarpus densiflorus) is one of the most susceptible host species, but the cause of host mortality is poorly understood. Previous research...

  • Evaluation of Fusarium proliferatum Mycotoxin Profiles in Infected Garlic Cloves

    Creator:
    Rossi, Francesca
    Abstract:
    Fusarium proliferatum is a fungus found in soils which produces the mycotoxin group known as fumonisins. Of human concern due to hepato-, nephro- and neurotoxicity, the threat of fumonisins lies within several food items, including corn, wheat sorghum, asparagus and, more recently, garlic. Manifesting as ““garlic rot”,” F. proliferatum infection...

    Creator:
    Gallagher, Scott V.
    Abstract:
    The six stories within, "Still and Silent," "Cold Comfort," "The King of Porn," "Miscuts," "In Between," and "Renovations," are part of a work in progress. They attempt to show how the characters, although they may seem to struggle for independence from the family unit, are in fact strengthening the bonds...

  • Potential susceptibility of tanoak associated and rare ericaceous plant species of southwestern Oregon to Phytophthora ramorum

    Creator:
    Zanzot, James W.
    Abstract:
    The sudden oak death pathogen, Phytophthora ramorum, is present in southwestern Oregon, and while an eradication effort is underway, the potential impact of the polyphagous pathogen on surrounding vegetation is unknown. Plant communities in the area are substantially different from those affected in California, although tanoak (Lithocarpus densiflorus), evergreen huckleberry...

  • Viability and infective potential of Phytophthora pini zoospores in a recirculating irrigation system

    Creator:
    Shay, Sarah D.
    Abstract:
    Phytophthora pini Leonian, recently re-established from P. citricola I, is a pathogen with a wide range of forest and nursery hosts. It causes foliar infections in horticultural nurseries in Oregon, where recirculating irrigation systems are common. Increased use of recirculating irrigation systems may contribute to disease caused by waterborne plant...

  • Phytophthora ramorum within an Oregon tanoak forest : quantifying inoculum within canopy throughfall vs. soil splash

    Creator:
    Benemann, Silvia, E.
    Abstract:
    Phytophthora ramorum continues to cause extensive mortality of tanoaks in southwestern Oregon. Rain readily washes inoculum down through the canopy, causing new infections on the lower parts of the tree and neighboring host plants. Although this aspect of dispersal is well understood, the relative importance of infested soil and leaf...

  • Pathways of infection of Phytophthora ramorum in rhododendron

    Creator:
    Lewis, Carrie D.
    Abstract:
    Phytophthora ramorum, a plant pathogen, is the cause of sudden oak death and ramorum blight and shoot die-back. It has a wide host range including many native forest species and common nursery plants. The lack of knowledge regarding infection biology of P. ramorum limits our understanding of its ecology and...
