  • Individual and demographic responses of the gray-tailed Vole (Microtus canicaudus) to an endocrine disruptor

    Creator:
    Caslin, Tracie M.
    Abstract:
    In an experimental field study, populations of gray-tailed voles (Microtus canicaudus) were exposed to a commercial formulation of vinclozolin, a fungicide effective for disease control on ornamental plants, turf grasses, and fruits and vegetables. Vinclozolin has been shown in laboratory experiments to behave as an androgen antagonist, impairing the reproductive...

  • Parental care of peregrine falcons in interior Alaska and the effects of low-altitude jet overflights

    Creator:
    Palmer, Angela G.
    Abstract:
    To assess the impact of low-altitude jet overflights on parental care, we examined nest attendance, time-activity budgets, and provisioning rates of 21 Peregrine Falcon (Falco peregrinus) pairs breeding along the Tanana River, Alaska in 1995 and 1996. Several intrinsic and extrinsic factors influenced attributes of nesting behavior. Female nest attendance...

  • Untangling the complexity of nearshore ecosystems : examining issues of scaling and variability in benthic communities

    Creator:
    Schoch, G. Carl
    Abstract:
    The objective of this research was to improve our understanding of how changes in the environment affect ecological processes. Change detection is often confounded by the large variation found in ecological data due to the difficulty of finding replicates in nature. Intertidal communities were chosen for studies of biophysical interactions...

  • Daily activity patterns, survival, and movements of red tree voles (Arborimus longicaudus) in western Oregon

    Creator:
    Swingle, James Kerr
    Abstract:
    We radiocollared a sample of 61 red tree voles in Douglas County, Oregon and monitored their movements to determine daily, seasonal, and sexual differences in behavior and home range attributes. We also collected information on nest attributes, survival, and dispersal of the radiocollared voles. Individual voles were monitored for periods...

  • Evaluation of cold in-place recycling of asphalt conrete pavements in Oregon

    Creator:
    Scholz, Todd
    Abstract:
    Significant use of cold in-place recycling (CIR) has occurred in Oregon since 1984 as an alternative to other rehabilitation techniques or to the reconstruction of distressed asphalt concrete (AC) pavements. Due to the initial success of the projects cold recycled during 1984-85, the Oregon Department of Transportation (ODOT) and Oregon...

  • Whale Cove (35LNC60) : an archaeological investigation on the central Oregon coast

    Creator:
    Rogers, Ann Bennett
    Abstract:
    The Whale Cove Site, 35LNC60, is a shell midden, showing occupations from 3010 B.P. to 330 B.P., spanning the Early and Late Littoral Periods. Analysis of mammalian faunal remains, bone and antler tools, lithics and discriptions of recovered shellfish artifacts allows for chronological refinement of the previously mentioned archeologically defined...

  • Developing models to predict favorable environments for rice blast

    Creator:
    Calvero, Silvino B.
    Abstract:
    Statistical analyses were used to develop predictive models of rice blast and to relate the favorability of environment to disease incidence and severity on different rice cultivars at five sites in Asia. The WINDOW PANE program was used to search for weather factors highly correlated with blast. Stepwise and r-square...

    Abstract:
    The purpose of this study was to investigate the relationship of family size, birth order, socioeconomic status, and parent-child relationships to young children's intellectual development. Seventy-four children, 39 boys and 35 girls, with a mean age of 4 years-8 months, and their parents (mothers and fathers), selected from 9 preschool...

    Abstract:
    Careful analysis and thoughtful synthesis will be necessary for expanding the envelope of ecological understanding. This work is my attempt at communicating both of these, in relation to three questions about our understanding of the structure and dynamics of biological diversity. These questions focus on a) advancing our understanding of...

  • Sensory and chemical analysis of 1997 Oregon Pinot noir enzyme treated wines

    Creator:
    Goldberg, Naomi
    Abstract:
    Pinot noir has a reputation for lower color stability than other red wine varieties. Because it has relatively low anthocyanin and phenolic content and lacks acylated anthocyanin pigments compared to other red vinifera varieties, color extraction and stability are particularly important. Varying the processing during fermentation of red wine can...
