  • 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...

  • The economics of a research program : knowledge production, cost, and technical efficiency

    Creator:
    Qin, Lin
    Abstract:
    Calls continually are made to provide economic assessments of research program achievements and efficiency. Yet little effort has been given to develop an assessment framework that would focus on the research discovery itself, treating the research manager as a producer and the research technology as a knowledge production function. The...

  • Predictability and constraints on the structure of ecological communities in the context of climate change

    Creator:
    Barner, Allison K.
    Abstract:
    Ecologists must increasingly balance the need for accurate predictions about how ecosystems will be affected by climate change, against the fact that making such predictions at the ecosystem-level may be infeasible. Although information about responses of individual species to a changing environment is increasing, scaling such information to the community...

  • Habitat characteristics associated with abundance of band-tailed pigeons and use of mineral sites in the Pacific Northwest

    Creator:
    Overton, Cory T.
    Abstract:
    Index counts for the Pacific Coast race of the band-tailed pigeon (Columba fasciata monilis) have declined by -2% per year since survey efforts began in the 1950's and 60's. Mineral sites, important resources with high ion concentrations, are regularly visited by band-tailed pigeons which nest in surrounding forest lands. I...

  • The importance of egg size for the diversity of salmonids

    Creator:
    Leblanc, Camille A.
    Abstract:
    Understanding the origin and nature of intra specific biodiversity enables us to better conserve and manage animal populations. Biological diversity is seen at different scales and for different traits such as behavior, morphology, physiology, and life history. Behavior is especially important since behavioral changes are believed to precede changes in...

  • Exploration of statistical methods for synthesizing the effects of variable-retention harvesting on multiple taxa

    Creator:
    Lam, Tzeng Yih
    Abstract:
    Variable-retention harvesting was proposed to reduce loss of biodiversity and ecosystem processes associated with late-seral Douglas-fir (Pseudotsuga menziesii) forests in the Pacific Northwest. The Demonstration of Ecosystem Management Options experiment was established to test this hypothesis. Analysis presents various challenges to drawing statistical inferences about treatment effects. This dissertation explored...
