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...

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...

Mark-recapture estimates of population parameters for selected species of small mammals

Creator:: Hammond, Ellen L.
Abstract:: I used program CAPTURE to analyze 1,535 data sets for 33 North American species of small mammals for sources of variation in capture probabilities and to characterize species-specific responses to markrecapture trapping. CAPTURE incorporates seven models to account for all possible combinations of heterogeneity (h), behavioral response (b), and time...

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...

Foraging strategies of Glaucous-winged Gulls : influences of sea otter predation

Creator:: Irons, David B
Abstract:: Diets and foraging strategies of Glaucous-winged Gulls were studied in areas with and without sea otters in the western Aleutian Islands, Alaska. Gulls foraged on invertebrates (e.g., sea urchins, limpets, chitons, mussels, and others) in the rocky intertidal community and on fish at sea; this study was conducted on gulls...

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...

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,...

Roosevelt elk habitat use in the Oregon Coast Range

Creator:: Pope, Michael D. (Michael Dickens)
Abstract:: Few studies have evaluated non-migratory Roosevelt elk (Cervus elaphus roosevelti) interactions and habitat use on lands undergoing extensive timber removal. We captured and radio-tracked for 14 months representatives from 29 different bands of elk across a 37,000 ha area of Oregon's Coast Range. We identified 6 habitat variables within individual...

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...
