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...

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...

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...

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...

California condors in the Pacific Northwest : integrating history, molecular ecology, and spatial modeling for reintroduction planning

Creator:: D'Elia, Jesse
Abstract:: Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...

Evaluating space use and pesticide exposure risk for burrowing owls in an agricultural environment

Creator:: Gervais, Jennifer A.
Abstract:: Large burrowing owl (Aihene cunicularia) populations exist in areas of intensive agriculture in California, and pesticide exposure has been identified as a potential threat to population persistence. I evaluated breeding season use of agricultural fields by adult male owls using radio telemetry, and examined egg contaminant residues to estimate population-level...
