  • Evaluating space use and pesticide exposure risk for burrowing owls in an agricultural environment

    Creator:
    Gervais, Jennifer A.
    Abstract:
    Large burrowing owl (Aihene cunicularia) populations exist in areas of intensive agriculture in California, and pesticide exposure has been identified as a potential threat to population persistence. I evaluated breeding season use of agricultural fields by adult male owls using radio telemetry, and examined egg contaminant residues to estimate population-level...

  • Demography and habitat selection of northern spotted owls in post-fire landscapes of southwestern Oregon

    Creator:
    Clark, Darren A.
    Abstract:
    Several large wildfires in southwestern Oregon during the summers of 2001 and 2002 provided the opportunity to investigate the impacts of wildfire on northern spotted owls (Strix occidentalis caurina). I used radio-telemetry and demographic surveys to describe demographic performance and habitat selection of spotted owls in the areas burned by...

  • Short-tailed weasel space use in managed forests of western Oregon

    Creator:
    Linnell, Mark A.
    Abstract:
    Although short-tailed weasels (Mustela erminea) are important predators of small mammals, little is known about their space use, habitat selection, or vulnerability to predation in North America. To evaluate the effects of forest management and social structure on home range size and habitat selection of short-tailed weasels, I conducted a...
