  • Nesting ecology of mallards in the Willamette Valley of Oregon

    Creator:
    Rickerson, Eric V.
    Abstract:
    Although widely studied in many portions of North America, little is known about the specific habitat requirements of mallard ducks (Anas platyrhynchos) during the breeding season in western Oregon. I radio-marked 72 female mallards in the Willamette Valley of Oregon in March-April 1995-96 to document wetland habitat selection during pre-nesting...

  • Cross-cultural sweetness preferences for a sports drink

    Creator:
    Chung, Seo-Jin
    Abstract:
    Asian countries have become one of the largest export markets for US food developers during the past decade. Understanding consumer expectations and needs in a cross-cultural framework has gained importance for new products to succeed in the international markets. A sports-drink, which is a functional drink for athletes, has been...

  • Range-wide abundance and fluctuating asymmetry patterns of sagebrush-obligate passerine birds

    Creator:
    Krissman, Cortnie M.
    Abstract:
    North American sagebrush (Artemisia spp.) ecosystems are suffering from reductions in habitat extent and quality. Only about 50% of sagebrush remains from pre-settlement conditions, and much of the remaining habitat is fragmented or degraded by invasive species, fire suppression and overgrazing. Sagebrush-obligate species are experiencing population declines as a result...

  • A simulation tool for evaluating sensory data analysis methods

    Creator:
    Naini, Shuo
    Abstract:
    In cross-cultural studies, respondents from specific cultures may have different product preferences and scale usage. Combining data from different cultures will result in departures from the basic assumptions of analysis of variance (ANOVA) and loss of power in testing capability of finding product and culture differences. However, the result of...

  • Local weather, regional climate, and population dynamics of northern spotted owls in Washington and Oregon

    Creator:
    Glenn, Elizabeth M.
    Abstract:
    Since the early 1990s, declines in northern spotted owl (Strix occidentalis caurina) populations have been documented through extensive field surveys and range-wide demographic analyses. Although loss of late-successional forest has been credited as the primary cause for spotted owl population declines, environmental variation has also been shown to influence vital...

  • Habitat selection, reproductive success, and site fidelity of burrowing owls in a grassland ecosystem

    Creator:
    Ronan, Noelle A.
    Abstract:
    I used a comparative and experimental approach to examine nest habitat selection, reproductive success, and nest site fidelity of burrowing owls (Athene cunicularia) in a large, non-fragmented grassland in southwest California. In 1999, I compared habitat characteristics between nest sites (n = 31) and randomly selected, unoccupied burrows (n =...
