  • Diet and nutrition of female sage grouse during the pre-laying period

    Creator:
    Barnett, Jenny K.
    Abstract:
    Nutrition effects productivity of grouse. Females that obtain high nutrient diets in spring produce larger clutches and larger, more viable chicks than hens on less nutritious diets. Grouse select high nutrient foods to help ensure proper nutrition. Reduced productivity accounted for the decline of sage grouse (Centrocercus urophasianus) populations in...

  • Characteristics of forests at spotted owl nest sites in the Pacific Northwest

    Creator:
    Hershey, Kit
    Abstract:
    This study describes the composition and structure of forests within the immediate vicinity of Northern spotted owl (Strix occidentalis caurina) nest sites in the Klamath, Coast, and Cascade provinces of western Oregon and the Olympic province, Washington. I compared forest stand data collected at 105 nest sites with data from...

  • Habitat associations of woodpeckers at multiple scales in managed forests of the Southern Oregon Cascades

    Creator:
    Brett, Tiffany A.
    Abstract:
    I studied nest-site characteristics and habitat relationships for three species ofprimary cavity-nesting birds--hairy woodpecker (Picoides villosus), northern flicker (Colaptes auratus), and red-breasted sapsucker (Sphyrapicus ruber)-- over spatially heterogeneous landscapes in managed forests of the Southern Oregon Cascades during 1995 and 1996. The study was conducted on the Diamond Lake Ranger...

  • Control and biology of feral goats on Aldabra Atoll, Republic of Seychelles

    Creator:
    Rainbolt, Raymond E.
    Abstract:
    The control of feral goats (Capra hircus) and relevant aspects of their biology were studied on Aldabra Atoll, Republic of Seychelles, from October 1993 - May 1994 and November 1994 - May 1995. A total of 832 goats were killed on Aldabra using both the Judas goat technique and traditional...

  • Landscape composition around northern spotted owl nests, central Cascade Mountains, Oregon

    Creator:
    Swindle, Keith A.
    Abstract:
    This study describes the composition of forest landscapes surrounding northern spotted owl (Strix occidentalis caurina) nests in the central Cascade Mountains of Oregon. I compared forest composition around 126 owl nests in 70 pair territories with forest composition around 119 points drawn randomly from all terrestrial cover-types, and around 104...

  • Detection of deforestation and land conversion and estimation of atmosperic emissions and elemental pool losses from biomass burning in Rondônia, Brazil

    Creator:
    Guild, Liane S.
    Abstract:
    Biomass burning associated with deforestation and land use in the Amazon, greatly contributes to emissions as well as depletion of elemental pools. We identified deforestation and pasture formation and quantified resultant burning emissions and terrestrial aboveground elemental pool losses during a period of early colonization in the vicinity of Jamari,...

  • 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...

  • Behavioral responses of Rocky Mountain Elk (Cervus elaphus) to recreational disturbance

    Creator:
    Naylor, Leslie M.
    Abstract:
    I measured responses of free-ranging Rocky Mountain elk (Cervus elaphus) to recreational disturbance at Starkey Experimental Forest and Range, Oregon from April to October, 2003 and 2004. Resting, feeding, and travel activities of 13 cow elk were recorded at 5-minute intervals using Actiwatch™ motion sensors. Elk were subjected to four...

  • 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...

  • Human impacts on the ecology of bald eagles in interior Alaska

    Creator:
    Steidl, Robert J.
    Abstract:
    To assess the consequences of increased recreational activity on bald eagles (Haliaeetus leucocephalus), we studied factors that influenced their behavior and reproductive success in the Gulkana River basin, Alaska, from 1989 to 1993. Both extrinsic and intrinsic factors were associated with reproductive success. Productivity averaged 0.86 young fledged per occupied...
