Status and habitat preference of California bighorn sheep on Sheldon National Wildlife Refuge, Nevada

Creator:: Hansen, Michael Charles
Abstract:: A herd of California bighorn sheep (Ovis canadensis californiana), re-introduced to the area of Hell Creek on the Sheldon National Wildlife Refuge in northwestern Nevada, was studied from 15 June 1978 to 20 August 1980. Major vegetation and physiographic types were delineated and described. Habitat preferences were determined from field...

Exposure of coho salmon (Oncorhynchus lisutch) to petroleum hydrocarbons : effect on lipid metabolism and aryl hydrocarbon hydroxylase activity

Creator:: Caldarone, Elaine Marie
Abstract:: Coho salmon (Oncorhynchus kisutch) were exposed to sublethal levels of a water-soluble fraction (WSF) of Cook Inlet crude oil for periods ranging from 18 to 31 days, at four acclimation temperatures. The fatty acid composition of phospholipids extracted from muscle, gill, liver, and brain tissues, and, at three of the...

Quantitative genetics of chum salmon, Oncorhynchus keta (Walbaum)

Creator:: Smoker, William Williams
Abstract:: Chum salmon from different stocks were bred together in two experiments. Three stocks contributed gametes to one experiment, two stocks to another. Sibling groups of eggs, alevins, and fry were maintained in a common environment. Variability of development rates, rearing performance, susceptibility to disease, and behavioral traits was partitioned into...

The development and maintenance of stream community structure and organization

Creator:: Wevers, Mary Jo
Abstract:: The goal of this study was to better understand stream communities through a perspective that might make their structure, organization, and development more understandable. This goal was approached through the following objectives: 1. To determine the assemblages of stream organisms and define subsystems within a stream community. 2. To explain...

Ecology of aquatic habitats associated with stream margins

Creator:: Moore, Kelly M. S.
Abstract:: The morphology and ecological importance of habitats associated with the margin of third-order stream channels in the Oregon Cascades were studied in streams in three different riparian types: 450-year-old conifers, 40-year-old alder, and an open, herbaceous-dominated clearcut. Margins, backwaters, and side channels in streams create important habitat for fry of...

Winter ecology of juvenile coho salmon (Oncorhynchus kisutch) in modified and unmodified sections of a coastal stream

Creator:: Phillips, Stephen H. (Stephen Homes), 1957-
Abstract:: Natural and gabion modified habitats containing coho salmon (Oncorhynchus kisutch) were observed and measured seasonally in East Fork Lobster Creek, a fifth order stream in western Oregon. Coho salmon usually inhabited backwater and secondary channel pools in winter. Large wood debris complexes and undercut banks were the primary sources of...

Cortisol and the immune system of juvenile Pacific salmon during stress and development

Creator:: Maule, Alec G.
Abstract:: Plasma concentrations of cortisol, a glucocorticoid hormone that is immunosuppressive in mammals, increase during stress and smoltification of salmonids. There was a reduction in the ability of lymphocytes to generate antibody producing cells (APC) in vivo concurrent with increased plasma cortisol titers during smoltification of coho salmon (Oncorhvnchus kisutch). Cortisol...

Systematics and ecology of chubs (Gila : Cyprinidae) of the Alvord Basin, Oregon and Nevada

Creator:: Williams, Jack Edward
Abstract:: Seventeen populations of Gila Baird and Girard are identified from the Alvord Basin of southeastern Oregon and northwestern Nevada. Gila in the Alvord Basin occupy a wide range of habitats, including warm springs, cool springs, creeks, reservoirs, and a thermal lake. These populations became isolated in remnant habitats when waters...
