  • Foraging ecology of barred owls where they are outcompeting the threatened northern spotted owl

    Creator:
    Baumbusch, Ryan C.
    Abstract:
    Following European-American colonization of North America and associated landscape changes, barred owls (Strix varia) underwent a dramatic expansion of their historical range. The barred owl expanded across the previously tree-less Great Plains that had limited their distribution, and into the forests along the west coast. In these western forests they...

  • The Evolution of Scleractinian Microbial Symbionts

    Creator:
    McMinds, Ryan C.
    Abstract:
    The modern world has presented many threats to the health and stability of ecosystems worldwide. One of the most biodiverse ecosystems, coral reefs, faces particularly strong pressures, and is already declining rapidly in complexity and area. Although the stressors that affect reefs are diverse, ranging from nutrient pollution to overfishing,...

  • Breeding qualitative and quantitative traits for potatoes in the Columbia Basin

    Creator:
    Graebner, Ryan C.
    Abstract:
    The cultivated potato (Solanum tuberosum L.) is one of the world’s most important staple crops, ranked fourth after maize, rice, and wheat. While the potato’s success is due largely to its high yield, it also benefits from its broad global acceptance, and its ability to be used by the consumer...

  • Germplasm design, gene discovery, and variety release: breeding barley for the Pacific Northwest

    Creator:
    Graebner, Ryan C.
    Abstract:
    This thesis consists of three manuscripts addressing separate components of barley breeding, plus an introduction and a conclusion summarizing the status of barley in the Pacific Northwest, plus the implications of the research presented in this thesis. In the first manuscript, a package written for the statistical software "R" that...

  • Suitability of diverse composts as soil amendments for highbush blueberry (Vaccinium corymbosum L.)

    Creator:
    Costello, Ryan C.
    Abstract:
    Highbush blueberry (Vaccinium corymbosum L.) is adapted to soils with high organic matter and acidic pH. Composts provide organic matter and nutrients for growing blueberry in mineral soils, but many composts are high in pH and soluble salts. Acidification with elemental sulfur (S°) can remedy high pH, but the process...

  • Characterization of the onset of charged particle equilibrium for photon dose to skin

    Creator:
    Ryan, Michael C.
    Abstract:
    In the U.S., the Nuclear Regulatory Commission (NRC) is responsible for setting annual dose limits. For cases of hot particle contamination these limits are set at depths in skin of 7 mg/cm², 300 mg/cm², and 1000 mg/cm². However, at such shallow depths, the lack of charged particle equilibrium (CPE) precludes...

  • Molecular characterization and genetic recombination of snakehead rhabdovirus

    Creator:
    Johnson, Marc C.
    Abstract:
    The complete genome of snakehead rhabdovirus (SHRV) was cloned and molecularly characterized. This was initially accomplished through the sequence determination of its glycoprotein gene and the phylogenetic analysis of this gene with orthologous genes from other rhabdoviruses. The phylogenetic analysis revealed that SHRV groups with viruses of the genus Novirhabdovirus....

  • Vitamin E with the addition of flaxseed to create designer eggs

    Creator:
    Johnson, Rebecca C.
    Abstract:
    Two experiments were conducted to determine the effect of various levels of vitamin E on egg yolk. A diet of corn-flax-soybean meal was fed to layers and α-tocopherol content in eggs, egg production, and egg quality were evaluated. In experiment 2, vitamin E toxicity was also determined. In experiment 1,...

  • Benchmarking in foodservice operations

    Creator:
    Johnson, Bonnie C.
    Abstract:
    The objective of this study was to identify usage of foodservice performance measures, important activities in foodservice benchmarking, and benchmarking attitudes, beliefs, and practices by foodservice directors. The design of this study included two parts: (1) eleven expert panelists involved in a Delphi technique to identify and rate importance of...

    Johnson, Robert C. (Robert Carl)
    Abstract:
    This paper is devoted to the study of families of tangent lines to curves in Euclidean three dimensional space by the medium of a particular representation for lines. First, a ring of elements called dual numbers is described, and a vector space over this ring, whose elements are called dual...
