  • Population ecology of the Columbian white-tailed deer

    Creator:
    Gavin, Thomas Alan
    Abstract:
    A population of Columbian white-tailed deer (CWTD) was studied on a refuge (790 ha) in southwestern Washington during 1972-77. Quality of habitat was considered good for these deer and total population size remained between 164-230 as determined by mark-recapture methods during November. Population size declined significantly between the winters of...

  • Nesting and foraging ecology of band-tailed pigeons in western Oregon

    Creator:
    Leonard, Jerome Patrick
    Abstract:
    Pacific Coast band-tailed pigeons (Columba fasciata) have declined markedly during the past several decades. Despite implementation of increasingly restrictive hunting regulations, populations have shown minimal signs of recovery. I radio-marked 127 adult band-tailed pigeons in the central Oregon Coast Range in April-May of 1993-95 to document nesting chronology and productivity,...

  • Ecology of female northern pintails during winter in the San Joaquin Valley, California

    Creator:
    Fleskes, Joseph P.
    Abstract:
    I radio-tagged 191 Hatch-Year (HY) and After-Hatch-Year (AHY) female northern pintails (Anas acuta) in the San Joaquin Valley (SJV), California and studied their movements, habitat use and survival during August March, 1991-94. Overall, 94.3% wintered in central California; the highest percentage left during the 1991 drought. Tulare Basin and Mendota...

  • Foraging ecology of prairie falcons in northern California

    Creator:
    Haak, Bruce A.
    Abstract:
    Nine Prairie Falcons (Falco mexicanus) were radio-tagged in northern California during the spring and summer of 1976 and 1977 to study foraging behavior. The mean home range size for 3 males was 227.8 km²; largest portions of the home range were used during the incubation period. Shifts in foraging areas...

  • Improving Projections of Tidal Marsh Persistence under Climate Change with Remote Sensing and Site-Specific Data

    Creator:
    Buffington, Kevin J.
    Abstract:
    Tidal marshes are dynamic ecosystems that are threatened by climate change and sea-level rise. To characterize baseline condition and historic climate sensitivities, and improve projections into the future, new methods are required that integrate data from the field and remote sensing platforms. Marsh elevation response models can be calibrated with...

  • California condors in the Pacific Northwest : integrating history, molecular ecology, and spatial modeling for reintroduction planning

    Creator:
    D'Elia, Jesse
    Abstract:
    Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...
