Stream habitat utilization and behavior of sympatric and allopatric wild cutthroat trout (Salmo clarki) and hatchery coho salmon (Oncorhynchus kitsutch)

Creator:: Jacobs, Steven Edward
Abstract:: The behavior and stream habitat utilization of juvenile hatchery-reared coho salmon (Ovicozihynchus kisutch) and wild cutthroat trout (Salmo clarki) were examined to assess the nature of interactions between the species potentially resulting from introductions of hatchery coho salmon in streams. Habitat utilization was monitored in Mill Creek, Polk Co., Oregon...

Neritic reef fishes off central Oregon : aspects of life histories and the recreational fishery

Creator:: McClure, Robert Edward
Abstract:: Recreational angling pressure has recently increased in the neritic reef areas off the central Oregon coast. This study describes weight-length and age-length relationships as well as ages at sexual maturity of the black, blue, canary, yelloweye, and yellowtail rockfish (Sebastes melanops, S. mystinus, S. pinniger, S. ruberrimus, and S. flavidus,...

Occurrence and relative abundance of small mammals associated with riparian and upland habitats along the Columbia River

Creator:: Hinschberger, Mark Steven
Abstract:: A small mammal inventory of occurrence and relative abundance was conducted in riparian and upland habitats in six segments along the lower Columbia River from the river mouth to McNary Dam (river mile 292) during 1974 and 1975 by removal trapping on standardized trap lines. Analysis of variance was used...

Towards an Integrated Decision Tool for Managing Wildlife with Visitor Restrictions in Glacier Bay National Park

Creator:: Whitlock, Steven L.
Abstract:: The National Park Service has a dual mission of providing public access to exceptional natural resources, but in a manner such that these resources are left “unimpaired for the enjoyment of future generations.” Human activities in parks undoubtedly affect wildlife, but the degree to which such activities cause impairment is...

Home range and habitat use by Roosevelt elk in Olympic National Park, Washington

Creator:: Jenkins, Kurt Jeffrey
Abstract:: This research provides information on the distribution of an unexploited Roosevelt elk population in unaltered habitat in Olympic National Park. Radio-telemetry was used to document home range and habitat use by 11 adult cow elk in the Hoh Valley during March 1978, from 10 June-15 September 1978, and from 1...

Effects of maternal age on reproductive success in black rockfish, Sebastes melanops

Creator:: Bobko, Stephen J.
Abstract:: From 1996 through 1998 I collected mature female black rockfish off Oregon and examined ovaries and otoliths to estimate weekly, age-specific larval production. In all reproductive seasons, older black rockfish extruded larvae earlier in the season, followed by progressively younger fish. Each year, beginning in May, I collected young-of-the-year (YOY)...

Greater Sage-Grouse movements and habitat use during winter in central Oregon

Creator:: Bruce, Jennifer R., Robinson, W. Douglas, Petersen, Steven L., and Miller, Richard F.
Abstract:: Greater Sage-Grouse (Centrocercus urophasianus) depend on sagebrush habitat for food and cover during winter, yet few sage-grouse winter ecology studies have been conducted. During January and February 2007, we monitored 22 radio-collared sage-grouse (7 females and 15 males) in central Oregon to characterize winter habitat use and movement patterns. We...

The effects of prescribed burning on small mammal communities in Lava Beds National Monument, California

Creator:: Frenzel, Richard Wilmarth
Abstract:: The effects of prescribed burning on the abundance, species composition, and reproduction of small mammals were studied over a one year period. Two burn areas were studied, one in sagebrush/ bunchgrass and one in cheatgrass. The short-term effects were studied using monthly mark-recapture trapping on two treatment and two control...

River-dependent bird species as potential indicators of ecosystem response to removal of dams on the Elwha River, Washington

Creator:: Blackie, Barbara
Abstract:: If two dams on the Elwha River are removed, the ecosystem will be open to the downstream flow of sediments and the upstream flow of marine nutrients in the form of anadromous fish. Nutrient enrichment may influence trophic dynamics of the entire ecosystem, extending beyond the aquatic boundary. I assessed...
