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...
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...
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...
