Relative abundance and habitat associations of small mammals in two forest types in southern Oregon

Creator:: Johnston, Aaron N.
Abstract:: I studied small-mammal communities and their response to grazing in mixed-conifer forests and oak woodlands in the Cascade-Siskiyou National Monument in southern Oregon. My objectives were to (1) compare small-mammal communities among forest types and grazing intensities, (2) identify riparian affiliated species, and (3) describe microhabitat associations. Over two years,...

Juvenile survival and birth-site selection of Rocky Mountain elk in northeastern Oregon

Creator:: Rearden, Spencer N.
Abstract:: With declining populations and low calf recruitment in northeastern Oregon, much interest has been generated to study the survival rates and causes of mortality of Rocky Mountain elk (Cervus elaphus nelsoni). I investigated the causes of elk calf mortality and the effects of predation risk on birth-site selection by cow...

Breeding chronology, habitat utilization and nest-site selection of the long-billed curlew in northcentral Oregon

Creator:: Pampush, Geoffrey J.
Abstract:: Breeding ecology of long-billed curlews in Umatilla and Morrow Counties, Oregon, was studied during the spring and summer of 1978 and 1979. The first curlews were observed in the study areas on 16 and 19 March of 1978 and 1979, respectively. Earliest clutch completion and onset of incubation was on...

Survival, movements and habitat selection of pygmy rabbits (Brachylagus idahoensis) on the Great Basin of southeastern Oregon and northwestern Nevada

Creator:: Crawford, Justin A.
Abstract:: I investigated survival, movements, home range sizes, and habitat selection of pygmy rabbits (Brachylagus idahoensis) in southeastern Oregon and northwestern Nevada from June 2005 to June 2007. I trapped 298 rabbits on four sites and fitted each with radio transmitters. More than 13,000 locations of telemetered rabbits were recorded. I...

Movements and habitat asociations of northern flying squirrels in the Central Oregon Cascades

Creator:: Martin, Karl J.
Abstract:: We used radio-telemetry techniques to estimate home range size, movements, den sites, and habitat selection of 39 northern flying squirrels (Glaucomys sabrinus) in 2 old- and 2 second-growth stands in the central Oregon Cascades. Sampling periods were at night during summer and fall of 1991-92. Home ranges were smaller for...

Small-mammal herpetofauna abundance in riparian and upslope areas of five forest conditions

Creator:: Gomez, Douglas M.
Abstract:: I compared species composition and relative abundance of'small mammals and herpetofauna between riparian and upslope habitats among 5 forest types. Riparian- and upslope- associated species were identified based on capture frequency. Small mammal species richness was similar between stream and upslope habitats and among the 5 forest types. There were...

Movements, habitat associations, and survival of Columbian white-tailed deer in western Oregon

Creator:: Ricca, Mark A.
Abstract:: Columbian white-tailed deer (Odocoileus virginianus leucurus, CWTD) are a geographically isolated and federally endangered sub-species for which there is a paucity of recent ecological information. I described and examined sources of variation in spatial use patterns (i.e. home range, areas of concentrated use, and movements), habitat associations, and survival for...

Habitat use and densities of cavity-nesting birds in the Oregon Coast Range

Creator:: Nelson, S. Kim
Abstract:: I studied abundance patterns and habitat use of eight cavitynesting bird species in the Coast Ranges of Western Oregon during the spring and summer of 1985 and 1986. Three age classes of unmanaged Douglas-fir (Pseudotsuga menziesii) stands were selected for study: young (40-80 yrs), mature (80-200 yrs), and old-growth (>200...

Influence of limited access roads on Roosevelt elk in the Oregon Coast Range

Creator:: Cole, Eric K.
Abstract:: No studies have evaluated the effects of limited vehicle access on movements, survival and habitat use of Roosevelt elk (Cervus elaphus roosevelti) . We installed twenty gates, restricting motorized vehicle access by the public in seven discrete Road Management Areas (RMAs), comprising 35% of the study area. We radio-tracked 31...
