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...

Roosevelt elk habitat use in the Oregon Coast Range

Creator:: Witmer, Gary William
Abstract:: Daily and seasonal habitat use by Roosevelt elk was investigated in the Oregon Coast Range on managed, public forestland. Over 3,700 locations of 6 radio-collared cow elk were recorded during 12 consecutive months. Two elk formed part of a north band and 4 elk were part of a south band....

Comparative behavior of the progeny of hatchery and wild steelhead trout (Salmo gairdneri)

Creator:: Bieber, Glen F.
Abstract:: The objectives of this study were to determine whether changes in the selective pressures which occur in a hatchery could cause inherited modifications in the behavior of steelhead trout (Salmo gairdneri) that would affect their survival in the wild. Environmental effects on the behavior of the offspring of hatchery and...

Characterizing coal and mineral mines as a regional source of stress to stream fish assemblages

Creator:: Daniel, Wesley M., Infante, Dana M., Hughes, Robert M., Tsang, Yin-Phan, Esselman, Peter C., Wieferich, Daniel, Herreman, Kyle, Cooper, Arthur R., Wang, Lizhu, and Taylor, William W.
Abstract:: Mining impacts on stream systems have historically been studied over small spatial scales, yet investigations over large areas may be useful for characterizing mining as a regional source of stress to stream fishes. The associations between co-occurring stream fish assemblages and densities of various “classes” of mining occurring in the...

Prey availability overrides cover in determining growth and abundance of stream-dwelling cutthroat trout

Creator:: Wilzbach, Margaret A.
Abstract:: The abundance and biomass of cutthroat trout (Salmo clarki) have been found to be greater in logged than in forested streams of the Oregon Cascades. Although certain prey taxa increase in abundance following logging, habitat stability generally decreases and cover structures are removed. Research was conducted to examine the manner...

Environmental contaminants and ecology of bald eagles in southcentral Oregon

Creator:: Frenzel, Richard Wilmarth
Abstract:: Food habits and levels of organochlorine compounds, lead, and mercury in resident and wintering bald eagles were studied in southcentral Oregon and California, 1979-83. Food habits were assessed by examination of castings from winter communal roosts, identification of 2938 prey items found at nest sites and foraging areas, and observations...

Elemental Markers in Elasmobranchs: Effects of Environmental History and Growth on Vertebral Chemistry

Creator:: Smith, Wade D., Miller, Jessica A., and Heppell, Selina S.
Abstract:: Differences in the chemical composition of calcified skeletal structures (e.g. shells, otoliths) have proven useful for reconstructing the environmental history of many marine species. However, the extent to which ambient environmental conditions can be inferred from the elemental signatures within the vertebrae of elasmobranchs (sharks, skates, rays) has not been...

A hierarchical stream habitat classification system: development and demonstration

Creator:: Frissell, Christopher A.
Abstract:: Classification of Streams and stream habitats is useful for research involving establishment of monitoring stations, determining local impacts of land use practices, generalization from site-specific data, and assessment of basin-wide, cumulative impacts of human activities on streams and their biota. This thesis presents a framework for a hierarchical classification system,...
