  • Evaluating microbial indicators of environmental condition in Oregon rivers

    Creator:
    Pennington, Alan Travis
    Abstract:
    Traditional public health bacterial indicators of water quality and the Biolog® system were evaluated to compare their response to other indicators of stream condition with the state of Oregon and between ecoregions (Coast Range, Willamette Valley, Cascades, and Eastern Oregon). Forty-three randomly selected Oregon rivers were sampled during the summer...

  • Western juniper encroachment into aspen communities in the Northwest Great Basin

    Creator:
    Wall, Travis G.
    Abstract:
    In the Northwest Great Basin, aspen (Populus tremuloides) communities uniquely contribute to the biodiversity of a semi-arid, sagebrush-dominated landscape. In this same region, western juniper (Juniperus occidentalis) is encroaching into aspen stands. This study determined the timing, extent, and some of the effects of this expansion. Aspen stands below 2,133...

  • Marker development, genome mapping, and cloning of candidate disease resistance genes in sunflower, Helianthus annuus L

    Creator:
    Gedil, Melaku Ayele
    Abstract:
    The level of polymorphisms of many biochemical and DNA markers are low in cultivated sunflower (Helianthus annuus L.). The number of mapped public DNA markers is limited. Molecular markers have not been developed for the most important diseases of sunflower, such as downy mildew. The objectives of this study were...

  • Taxonomy and evolution of the Orthotyline genus Lopidea (Heteroptera: miridae)

    Creator:
    Asquith, Adam
    Abstract:
    The genus Lopidea Uhler is revised for America north of Mexico. The relationship of Lopidea to other orthotyline genera is discussed and it is proposed that the genus Ilnacora Reuter is the sister group of Lopidea. Forty-eight species of Lopidea are recognized in North America, one of which is described...

  • Women's perceptions of their children's experiences in domestic violence

    Creator:
    Wood, Barbara L.
    Abstract:
    Ten female survivors of physically assaultive domestic violence were interviewed three times each in a feminist, qualitative study designed to access their perceptions about their children's experiences in domestic violence. All participants had children living with them at the time of the abuse and were one to five years out...

  • Flux Sampling Errors for Aircraft and Towers

    Creator:
    Mahrt, L.
    Abstract:
    Various errors and influences leading to differences between tower- and aircraft-measured fluxes are surveyed. This survey is motivated by reports in the literature that aircraft fluxes are sometimes smaller than tower-measured fluxes. Both tower and aircraft flux errors are larger with surface heterogeneity due to several independent effects. Surface heterogeneity...

  • Valuing urban wetlands : a property pricing approach

    Creator:
    Mahan, Brent L
    Abstract:
    Wetlands play an important role in our social and economic well being. Many services wetlands provide, such as wildlife habitat, recreation, and aesthetics, are collective goods. Because these services are not represented in a market, an over supply of wetlands converted to other uses and an under supply of protected...

  • Effects of jet aircraft overflights and other potential disturbances on behavioral responses and productivity of nesting peregrine falcons

    Creator:
    Nordmeyer, Dana L.
    Abstract:
    In order to examine the potential impact of military jet overflights and other disturbances on productivity of peregrine falcons (Falco peregrinus), we observed behavioral reactions of peregrines to disturbances at nests along the Tanana River, Alaska during the 1995-1997 breeding seasons. Military jets conducted low-altitude flights over a sample of...

  • A paradigmatic framework for flight safety

    Creator:
    Routledge, Garry L.
    Abstract:
    Statistically, travel by air is one of the safest forms of transportation. Yet we continue to experience aviation tragedies. Do we fully understand flight safety or is there another way of looking at the problem? In this work a new way of approaching the question of flight safety is developed,...

  • Fescue taxonomy in the Pacific coast states

    Creator:
    Wilson, Barbara L.
    Abstract:
    Accurate taxonomy is essential to preservation and management of native grasses. Four problems in fescue taxonomy were investigated: the identity of the native fescue that dominates western Oregon and Washington prairies, the relationship of native Festuca roemeri to closely related grasses, the status of F. howellii and F. washingtonica, and...
