  • Black bear population ecology

    Creator:
    Lindzey, Frederick Grier
    Abstract:
    Despite relatively mild weather, black bears (Ursus americanus) in southwestern Washington entered dens and remained for an average of 126 days. Bears entered their dens during a 5-week period which began on 21 October. A significant difference (P < 0.05) was found among the average dates of den entrance of...

  • The ecology of Mountain Quail in Oregon

    Creator:
    Pope, Michael D. (Michael Dickens)
    Abstract:
    Mountain Quail (Oreortyx pictus) populations have declined in many areas of the western Great Basin during the past century. Yet the life history of this species is little known. From 1997 to 2000, I studied radio-marked Mountain Quail in Hell's Canyon in northeastern Oregon, in the Cascade Mountains of southwestern...

  • Ecology of feral pigs on Santa Catalina Island

    Creator:
    Baber, Daniel W.
    Abstract:
    A feral pig population on Santa Catalina Island, California, was studied for 17 months beginning in July 1980. Density was estimated to be 21 to 34 pigs/km² (95% confidence interval) using capture-recapture techniques. Dry season home ranges determined from radio-telemetry data were small and differed significantly between boars and sows....

  • Ecology of Great Basin Canada goose broods in southcentral Washington

    Creator:
    Eberhardt, Lester E.
    Abstract:
    The ecology of female Great Basin Canada geese (Branta canadensis moffitti) and their broods was studied during the rearing seasons of 1983 and 1984 on the Columbia River in southcentral Washington. The movements and activities of 41 adult female geese, marked with radio-transmitters, and their broods were monitored. Adult female...

  • Giant gartersnake spatial ecology in agricultural and constructed wetlands

    Creator:
    Valcarcel, Patricia M.
    Abstract:
    The spatial ecology of a species is a vital component of informed management and restoration plans, yet little is known about how animals use restored or constructed habitat. We assessed home ranges, core areas, and habitat selection of the federally threatened Giant Gartersnake (Thamnophis gigas) using rice agricultural habitat and...

  • Beaver ecology on the west Copper River Delta, Alaska

    Creator:
    Cooper, Erin E.
    Abstract:
    Since the 1964 earthquake and geologic uplift, beavers (Castor canadensis) have expanded their historic range from the inland (outwash plain) Copper River Delta, Alaska to the once tidally influenced areas of the outer area (uplifted marsh). The uplift presents a unique opportunity to observe beaver expansion, habitat selection and influence...

  • Ecology of Columbian black-tailed deer fawns in western Oregon

    Creator:
    Pamplin, Nathan P.
    Abstract:
    Little is known about Columbian black-tailed deer (Odocoileus hemionus columbianus) because of their elusive nature and the logistical difficulty of studying them in densely forested and mountainous terrain. The Oregon Department of Fish and Wildlife has identified fawn survival as an important gap in the current knowledge of demography and...

  • Atlantic Puffin (Fratercula arctica) Foraging Ecology During Marine Heatwave Conditions

    Creator:
    Kennerley, William L.
    Abstract:
    Marine heatwaves (“MHWs”) are discrete periods of anomalously warm ocean conditions that can lead to shifts in the distribution and abundance of marine organisms. Low-trophic level, pelagic forage species are frequently among those affected by MHWs, often resulting in considerable impacts upon their predators. In the North Atlantic Ocean, Atlantic...
