Habitat classification and characteristics of small mammal and amphibian communities in beaver-pond habitats of the Oregon Coast Range

Creator:: Suzuki, Nobuya
Abstract:: During 1988-1989, stream habitat variables were compared between beaver-dam sites and unoccupied-stream sites to identify variables that may have been important for beaver (Castor canadensis) in selecting dam sites in the streams of the Drift Creek basin, Lincoln County, Oregon. Increasing valley floor width and grass/sedge cover and decreasing stream...

Habitat associations of small mammals and amphibians in the central Oregon Coast Range

Creator:: Martin, Karl J.
Abstract:: One of the goals of ecosystem management is to integrate management of many species and processes across a range of temporal and spatial scales. I investigated the relationship between small mammals and amphibians at 3 spatial scales. My objective was to identify, habitat associations of forest floor vertebrates at the...

Distribution, habitat associations, and conservation status of Pacific fisher (Pekania pennanti) in Oregon.

Creator:: Barry, Brent R.
Abstract:: Fishers (Pekania pennanti) are medium sized mustelids endemic to North America. Two fisher populations persist in Oregon: an indigenous population in southwestern Oregon, and a reintroduced population in the southern Cascade Mountains. Despite candidacy for listing under the Endangered Species Act, current information on fisher populations in Oregon is scarce....

The effects of thinning on forest-floor small mammals in the Coast Range of Oregon

Creator:: Larson, David J.
Abstract:: Thinning of young Douglas-fir forests has the potential to enhance structural diversity and improve habitat for wildlife. I examined the effects of thinning and thinning intensity on abundance and demographic characteristics of forest-floor small mammals in the Coast Range of Oregon 5 and 6 years after thinning had occurred. Thinning...

Small mammal distribution, abundance and habitat selection in managed riparian habitats of Bear Valley, eastern Oregon

Creator:: Tomas, Walfrido Moraes
Abstract:: Riparian zones are critical habitats for management because of their importance for both cattle production and wildlife, and a high potential for resource conflicts. Riparian management should address habitat and microhabitat features that sustain both livestock production and wildlife diversity. I conducted a study to determine how small mammal distributions...

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...

Small mammal micro- and macrohabitat selection in streamside ecosystems

Creator:: Doyle, Arlene T.
Abstract:: During summer and fall of 1981 to 1983, mark-recapture was conducted in riparian and upland habitats within old-growth and mature forests in the Cascade Range of Oregon. Number of individuals and species richness were greater in riparian than upland habitat. For most species, the mean adult weights and the percentages...

An analysis of a small mammal population census

Creator:: Schamberger, Melvin
Abstract:: During the spring of 1963 and 1964 an investigation of a small mammal community was made in McDonald Forest, near Corvallis, Oregon. The revised North American Census of Small Mammals procedure was used, and from this census the species composition of the community was determined. The relationships of several genera...

Causes of death and pathological findings in marine mammals stranded along the Oregon coast

Creator:: Stroud, Richard K.
Abstract:: Fifty-seven stranded marine mammals representing seven species were examined over a period of three years. The primary cause of death along with contributing factors, incidental pathology and parasites is reported for each animal examined. Gunshot wounds directly or indirectly caused the death of 14 of 44 seals and sea lions...
