  • 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...

  • Environmental contaminants and breeding biology of great blue herons in the Columbia River Basin

    Creator:
    Thomas, Carmen M.
    Abstract:
    Great blue heron (Ardea herodias) eggs and prey items were collected from six colonies on the Columbia and Willamette rivers and Puget Sound during 1994-95. Contaminant concentrations, reproductive success, and biomagnification factors (BMFs) were determined and effects of residue levels were measured by H4IIE rat hepatoma and ethoxyresorufin-O-dealkylase (EROD) bioassays....

  • Agricultural impacts on amphibian survival, growth, and distributions

    Creator:
    Baker, Nick J.
    Abstract:
    The potential impact of chemical contaminants and conservation practices on amphibians in agricultural landscapes is a key research topic globally. Amphibians represent a common group in many freshwater systems and are currently experiencing worldwide population declines. Global amphibian declines may be attributed to a number of causes, including habitat loss,...
