Range-use estimation and encounter probability for juvenile Steller sea lions (Eumetopias jubatus) in the Prince William Sound-Kenai Fjords region of Alaska

Creator:: Meck, Stephen R.
Abstract:: Range, areas of concentrated activity, and dispersal characteristics for juvenile Steller sea lions Eumetopias jubatus in the endangered western population (west of 144° W in the Gulf of Alaska) are poorly understood. This study quantified space use by analyzing post-release telemetric tracking data from satellite transmitters externally attached to n...

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...

Age-fecundity relationships in the striped seaperch Embiotoca lateralis from Yaquina Bay, Oregon

Creator:: Swedberg, Stephen Ernferd
Abstract:: A study was conducted at Yaquina Bay, Oregon, to determine the age-fecundity relationships in the striped seaperch Embiotoca lateralis. A questionnaire was sent to California, Oregon, and Washington to ascertain what regulations were in effect, and the value of the family Embiotocidae with regard to the sport and commercial harvest....

Seasonal life history of Oncorhynchus mykiss in the South Fork John Day River Basin, Oregon

Creator:: Tattam, Ian A.
Abstract:: Understanding seasonal changes in growth, survival, and movement rates is crucial to salmonid management. These life history characteristics provide a context for evaluation of management actions. We evaluated the life history of individually marked Oncorhynchus mykiss gairdneri in the South Fork John Day River basin in Northeastern Oregon. This thesis...

Characteristics of pools used by adult summer steelhead (Oncorhynchus mykiss) in the Steamboat Creek Basin, North Umpqua River, Oregon

Creator:: Baigun, Claudio Rafael Mariano
Abstract:: This study examined features of deep pool (>0.8 m mean depth) used by adult summer steelhead in Steamboat Creek (1991-1992). Steamboat Creek had a heterogenous thermal profile, with some segments exceeding preferred temperature of steelhead. Deep pools were scarce (4% of the total habitat units) and 39% of them were...

The Influence of Scale in a Structured Decision Making Framework for Chinook Salmon Management

Creator:: McDonnell, Kevin N.
Abstract:: The goal of my dissertation was to explore how scale influences stream restoration prioritization strategies for an anadromous species and identify influential uncertainties that exist at different scales. My objectives were to (1) produce a comprehensive review of the Chinook salmon management challenges in California’s Central Valley and identify the...

Total and available nutrients in manures for pond aquaculture

Creator:: Nath, Shree S.
Abstract:: The total amount of nitrogen and phosphorus in animal manures, and the proportion of this amount that becomes available as dissolved inorganic nitrogen and phosphorus within a month after manures are added to water were examined in the context of fertilization guidelines for pond aquaculture. A literature study was conducted...

Rare, endangered, and recently extirpated mammals in Oregon

Creator:: Olterman, James Howard
Abstract:: This paper lists, and gives individual accounts of, those Oregon mammals that at some time have been referred to as being of a status other than common. Although rare and endangered wildlife species were listed on a national level in the United States, the large areas of land included in...

Effects of Hypoxia on Consumption, Growth, and RNA:DNA Ratios of Young Yellow Perch

Creator:: Roberts, James J., Brandt, Stephen B., Fanslow, David, Ludsin, Stuart A., Pothoven, Steven A., Scavia, Donald, and Höök, Tomas O.
Abstract:: As in various freshwater and coastal marine ecosystems worldwide, seasonal bottom water hypoxia is a recurring phenomenon in Lake Erie's central basin. While bottom hypoxia can strongly affect sessile benthic animals, its effects on mobile organisms such as fish are less understood. We evaluated the potential for bottom hypoxia to...

Genetic patterns of demography and diversity in eastern North Pacific rockfishes (genus Sebastes)

Creator:: Johansson, Mattias L.
Abstract:: The 100 North Pacific rockfish species in the genus Sebastes are highly diverse. Rockfishes fertilize their eggs internally and release swimming larvae. Complex courting behaviors may allow female rockfish to be selective about their mates and may promote and maintain speciation. In this study, I applied genetic techniques to survey...
