Spatial and temporal dynamics of sediment and wood in headwater streams in the central Oregon Coast Range

Creator:: May, Christine L.
Abstract:: Channels that were scoured to bedrock by debris flows provided unique opportunities to calculate the rate of sediment and wood accumulation, to make inferences about processes associated with input and transport of sediment, and to gain insight into the temporal succession of channel morphology following disturbance. In an intensive investigation...

Quantitative Tools for Monitoring Strategy Evaluation and Assessment of Sea Turtle Populations

Creator:: Piacenza, Susan E. H.
Abstract:: Green sea turtles, Chelonia mydas, have endangered and threatened populations globally, but several populations show signs of population recovery. In Hawaii, nesting female green turtles have increased 5.7% year⁻¹ since 1973, but wide fluctuations in census counts of nesting females make recovery diagnosis difficult. For effective management planning, it is...

Mark-recapture estimates of population parameters for selected species of small mammals

Creator:: Hammond, Ellen L.
Abstract:: I used program CAPTURE to analyze 1,535 data sets for 33 North American species of small mammals for sources of variation in capture probabilities and to characterize species-specific responses to markrecapture trapping. CAPTURE incorporates seven models to account for all possible combinations of heterogeneity (h), behavioral response (b), and time...

Breeding chronology, habitat utilization and nest-site selection of the long-billed curlew in northcentral Oregon

Creator:: Pampush, Geoffrey J.
Abstract:: Breeding ecology of long-billed curlews in Umatilla and Morrow Counties, Oregon, was studied during the spring and summer of 1978 and 1979. The first curlews were observed in the study areas on 16 and 19 March of 1978 and 1979, respectively. Earliest clutch completion and onset of incubation was on...

Mate choice of wild spawning coho salmon (Oncorhynchus kisutch) in the Umpqua River, Oregon

Creator:: Whitcomb, Amelia C.
Abstract:: Evidence for reduced reproductive success (RS) of wild spawning hatchery-reared fish invites serious consideration with regard to the detrimental effects on subsequent generations of wild populations. Mate choice was evaluated as a potential mechanism contributing to these observed RS differences using a previous pedigree of wild spawning hatchery-reared and wild...

Electrofishing mark-recapture and depletion methodologies evoke behavioral and physiological changes in cutthroat trout (Oncorhynchus clarki)

Creator:: Mesa, Matthew G.
Abstract:: We examined the behavioral and physiological responses of wild and hatchery-reared cutthroat trout Oncorhynchus clarki subjected to a single electroshock, electroshock plus marking, and multiple electroshocking in natural and artificial streams. In a natural stream, trout released after capture by electrofishing and marking showed distinct behavioral changes: fish immediately sought...

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...

A review of the Gadopsidae, with a description of a new species from Tasmania

Creator:: Parrish, Richard H.
Abstract:: The taxonomic placement of Gadopsidae is discussed and an evaluation of its osteological relationships with related families is given. Similarities to the more primitive genera of the trachinoids, notothenioids, and uranoscopoids are noted and the inclusion of Gadopsidae in the Trachinoidae is recommended. A description of the geological history of...

An Evaluation of the Effects of Hatchery and Management Practices on Geomagnetic Orientation Behavior in Juvenile Pacific Steelhead Trout (Oncorhynchus mykiss)

Creator:: Scanlan, Michelle M.
Abstract:: Numerous populations of salmon and trout undergo extensive migrations, migrating from freshwater to the sea and throughout ocean basins. Years later they return to their natal streams with remarkable accuracy and precision. The outward migration is accomplished without the benefit of following experienced migrants or prior individual experience. Evidence suggests...
