  • Systematic studies of the genus Siphateles (Ostariophysi: Cyprinidae) from western North America

    Creator:
    Harris, Phillip M.
    Abstract:
    The minnow genus Siphateles is distributed throughout the Great Basin and adjacent drainages of western North America. Three species are currently recognized in the genus: S. alvordensis, Alvord chub, S. boraxobius, Borax Lake chub, and S. bicolor, the tui chub. S. bicolor has long been recognized as a widespread species...

  • Shrub epiphyte communities in relation to stand management in forests of western Oregon

    Creator:
    Rosso, Abbey L.
    Abstract:
    This dissertation describes the epiphyte communities on tall shrubs in forests of western Oregon, with a focus on potential effects of management practices on these communities. Shrubs and other hardwoods have recently gained recognition as hotspots of diversity for epiphytes in young conifer forests of the region. Yet little is...

  • The development and analysis of future agricultural landscapes

    Creator:
    Berger, Patricia A.
    Abstract:
    Alternative futures studies provide a way for policy-makers and stakeholders to investigate the future impacts of different management strategies by providing representations of possible outcomes. An alternative futures study was undertaken by the Pacific Northwest-Ecosystem Research Consortium for the Willamette River Basin, Oregon, USA, to determine how this regional system...

  • Analyses of noncanonical DNA structures

    Creator:
    Khuu, Patricia A.
    Abstract:
    The structural polymorphic nature of DNA has been long been recognized since the model of the right-handed B-DNA duplex proposed by James Watson and Francis Crick was accepted. Its malleability is thought to be critical in protein recognition and manipulation. In particular, it can form Holliday junctions, four-way DNA structural...

  • Population viability analysis of endangered plant species : an evaluation of stochastic methods and an application to a rare prairie plant

    Creator:
    Kaye, Thomas N.
    Abstract:
    Transition matrix models are one of the most widely used tools for assessing population viability. The technique allows inclusion of environmental variability, thereby permitting estimation of probabilistic events, such as extinction. However, few studies use the technique to compare the effects of management treatments on population viability, and fewer still...

  • Ecological subsidies to rocky shore communities : setting the stage for community dynamics in the Northeast Pacific

    Creator:
    Krenz, Christopher
    Abstract:
    This dissertation focuses on the importance of pelagic subsidies in the Northeast Pacific to rocky shore community regulation. My results document the patterns of pelagic subsidy supply, determine if those subsidies are correlated with community structure, and examine if community regulation differs between areas of high- and low-subsidies. Understanding how...

  • Lichen response to the environment and forest structure in the western Cascades of Oregon

    Creator:
    Martin, Erin P.
    Abstract:
    Lichens are an important part of the biota in western Oregon forests, where they perform valuable ecological roles and contribute significantly to biodiversity. Lichens in western Oregon are threatened by a number of factors including air pollution and land use practices. If we wish to maintain the persistence of lichens...

  • Seconds to hour scale photosynthetic responses in marine microalgae

    Creator:
    Laney, Samuel R.
    Abstract:
    Our view of phytoplankton has historically revolved around their inability to control their location in space. The term phytoplankton itself underscores this particular difference between phytoplankton and their sessile terrestrial counterparts. Yet there are other differences between land plants and the phytoplankton that are perhaps equally important, beyond this sessile-planktonic...

  • The great fires : Indian burning and catastrophic forest fire patterns of the Oregon Coast Range, 1491-1951

    Creator:
    Zybach, Bob
    Abstract:
    The purpose of this study is to examine the relationship between land management practices of Indian communities prior to contact with Europeans and the nature or character of subsequent catastrophic forest fires in the Oregon Coast Range. The research focus is spatial and temporal patterns of Indian burning across the...

  • Biological insertion of nanostructured germanium and titanium oxides into diatom biosilica

    Creator:
    Jeffryes, Clayton S.
    Abstract:
    There is significant interest in titanium oxide and germanium-silicon oxide nanocomposites for optoelectronic, photocatalytic, and solar cell applications. The ability of the marine diatom Pinnularia sp. to uptake soluble metal oxides from cell culture medium, and incorporate them into the micro- and nano-structure of their amorphous silica cell walls, called...
