  • Prescribed fire in Eastern Oregon ponderosa pine forests : relationships between soil fertility and ecology

    Creator:
    Grossmann, Emilie B.
    Abstract:
    I conducted two separate studies, both related to the impacts of spring and fall prescribed fire on ponderosa pine (Pinus ponderosa Dougl. ex Loud.) forest soils in Eastern Oregon. The studies were either conducted at or linked to four stands of ponderosa pine, in the Malheur National Forest. Each stand...

  • Assessment of the vulnerability of Oregon and Washington's natural areas to climate change

    Creator:
    Margaret, Massie H.
    Abstract:
    There are currently more than 580 natural areas in Oregon and Washington managed by 20 federal, state, local, and private agencies and organizations. The natural areas network is unparalleled in its representation of diverse ecosystems found in the region and may be an excellent collection of sites for monitoring long-term...

  • The role of the plasminogen activator system in the etiology of ovarian follicular cysts in dairy cattle

    Creator:
    McNeel, Anthony Kent
    Abstract:
    Cystic ovarian disease (COD) is an anovulatory condition in cattle that afflicts between 6-18% of all dairy cows in the US. Ovulation is dependent on the plasminogen activator (PA) family of proteases and protease inhibitor for proteolysis, culminating in follicular rupture. Failure of the follicle to ovulate suggests an aberration...

  • Studies on roles of lactic acid bacteria and yeast in the flavor of bakery products

    Creator:
    Yamada, Masahiko
    Abstract:
    Roles of lactic acid bacteria in flour pre-ferment and white bread were investigated. Volatile compounds produced by the organisms were identified using gas-liquid chromatography (GLC). Lactic acid bacteria were isolated from domestic commercial compressed yeast and active dry yeast. Numbers per gram of sample were 10⁸ to 10⁹ in compressed...

  • Disease invasion dynamics : brucellosis and tuberculosis in African buffalo (Syncerus caffer)

    Creator:
    Gorsich, Erin E.
    Abstract:
    Emerging infectious diseases in wild animals threaten global biodiversity as well as domestic animal and human health. Their unprecedented increase in conjunction with anthropogenically induced range shifts of endemic pathogens exposes hosts to novel parasite combinations, lending urgency to research on disease dynamics in wildlife systems. In natural populations, hosts...

  • An appraisal of risks and benefits in the provision of selenium for beef cattle

    Creator:
    Hathaway, Ronald L.
    Abstract:
    Three experimental grazing trials were conducted to explore the hypothesis that in the Klamath Basin, a higher level of selenium supplementation is necessary than those proven adequate elsewhere. Two forage species were investigated: Festuca arundinaeca and Agropyron repens, in 0.61 hectare plots, both grown in a selenium deficient soil area....

  • Mycorrhizal status of post-fire Pezizales

    Creator:
    Fujimura, Kei E.
    Abstract:
    Post-fire Pezizales often fruit seasonally approximately six weeks after a fire in successional groups over the course of two years. Two methods, pure culture synthesis and PCR-based identification, were used to determine if some of these species were mycorrhizal. Eleven fungal isolates, Anthracobia melaloma, Gyromitra infula, Helvella compressa, Morchella sp.,...

  • Comparison and analysis of small area estimation methods for improving estimates of selected forest attributes

    Creator:
    Goerndt, Michael E.
    Abstract:
    One of the most common practices regarding estimation of forest attributes is the partitioning of large forested subpopulations into smaller areas of interest to coincide with specific objectives of present and future forest management. New estimators are needed to improve estimation of selected forest attributes in small areas where the...

  • Biological oxidation of sorbitol

    Creator:
    Cummins, Joseph Thomas
    Abstract:
    The oxidation of sorbitol by soluble extracts of A. suboxydans proceeds by two pathways depending upon which pyridine nucleotide is present. In the presence of TPN, sorbose is formed. In the presence of DPN fructose is produced. Both products of the oxidation of sorbitol have been identified by paper chromatography,...
