Black bear population ecology

Creator:: Lindzey, Frederick Grier
Abstract:: Despite relatively mild weather, black bears (Ursus americanus) in southwestern Washington entered dens and remained for an average of 126 days. Bears entered their dens during a 5-week period which began on 21 October. A significant difference (P < 0.05) was found among the average dates of den entrance of...

The effects of sewage on the distribution and abundance of benthic animals in a Puget Sound bay

Creator:: Shapeero, William L.
Abstract:: The effects of discharged sewage on physico-chemical conditions and the distribution and abundance of marine benthic animals were studied in Shilshole Bay, a part of Puget Sound, off Seattle, Washington. For over 50 years prior to 1965, when this study was initiated, 87,300 pounds (32,400 pounds BOD) per day of...

Evaluation of baits and baiting techniques for Belding's ground squirrels

Creator:: Sullins, George Lamont
Abstract:: Quantitative data concerning bait preference and bait application were collected for Belding's ground squirrels (Spermophilus beldingi) during February-July 1975. Bait materials tested for preference were crimped oats, oatgroats, whole wheat, barley, rolled wheat, rye, chopped lettuce, chopped apple, oatgroats + Rhodamine B dye, oatgroats + starch paste, oatgroats + Rhoplex...

Relative resistances of three transferrin genotypes of coho salmon (Oncorhynchus kisutch) and their hematological responses to bacterial kidney disease

Creator:: Suzumoto, Bruce Kazuo
Abstract:: Juvenile coho salmon (Oncorhynchus kisutch) of three transferrin genotypes (AA, AC and CC) were experimentally infected with the causative agent of bacterial kidney disease (BKD) and mortalities observed. Six experimental and control groups were used: (1) bacteria-infected + no Fe⁺³ ; (2) bacteria-infected + low Fe⁺³ levels; (3) bacteria-infected +...

Evaluation of shrimp and crab processing waste as a feed supplement for mink (Mustela vison)

Creator:: Watkins, Bruce Ellsworth
Abstract:: Three products derived from shrimp processing waste (Pandalus jordani) and a protein concentrate extracted from king crab waste (Paralithodes camschatica) were evaluated as feed supplements for standard dark and sapphire pelter mink (Mustela vison) replacing approximately 10 and/or 20 percent of the protein in a standard wet diet (33 percent...

Transferrin polymorphism in a population of Nuttall's cottontail in central Oregon

Creator:: Skalski, John Raymond
Abstract:: Temporal changes in gene frequencies and genotype frequencies, monthly densities, survival rates, growth rates, trap susceptibility and home ranges were evaluated from 291 Nuttall's cottontails (Sylvilagus nuttallii) captured 950 times by livetrapping and 53 cottontails collected by shooting. Electrophoretic analyses of sera revealed protein polymorphism at the transferrin locus in...

A mendelian study of Crassostrea gigas

Creator:: Smoker, Janet Van Dusen
Abstract:: The genotype frequencies of one-year-old oyster spat (Crassostrea gigas) from parents of known genotype, are compared to the frequencies expected with Mendelian inheritance. The genotypes are characterized at three enzyme loci, Aspartate amino-transferase (AAT), Phosphohexose isomerase (PHI) and Leucine aminopeptidase (LAP), and a general protein locus. In this study expression...

Production, nest site selection, and food habits of ospreys on Deschutes National Forest, Oregon

Creator:: Lind, Gordon S.
Abstract:: A study of population trends, nest site selection, and food habits of ospreys (Pandion haliaetus carolinensis) nesting on the Bend District of the Deschutes National Forest, Oregon, was conducted during 1970 and 1971. Intensive observations were made of 95 nesting attempts of ospreys. Energy demands of the population were estimated...

Growth and survival of juvenile hatchery and wild steelhead trout, Salmo gairdneri, in streams

Creator:: Reisenbichler, Reginald R.
Abstract:: Relative growth and survival of offspring from matings of hatchery and wild Deschutes River (Oregon) summer steelhead trout, Salmo gairdneri, were monitored to determine if hatchery fish differ genetically from wild fish in traits which can affect the stock-recruitment relationship of wild populations. Four natural streams and a hatchery pond...

Seasonal properties of the coyote scent station index

Creator:: Griffith, Dennis Bradley
Abstract:: Six standard coyote scent station index lines and one scentless control line were repeatedly sampled from May through October, 1974, on a 400 square mile study area in Central Oregon. The scent station index remained relatively constant at a mean value of 0.025 from May through mid-August; increased to a...

Sulfobromophthalein disposition in rainbow trout (Salmo gairdneri) as influenced by carbon tetrachloride intoxication

Creator:: Gingerich, William H.
Abstract:: Clinical methods to diagnose specific organ dysfunction have not been evaluated in fishes. To determine if an accepted clinical test of mammalian liver function could be applied to fishes, the hepatic disposition of the organic anion sulfobromophthalein (BSP) was studied in rainbow trout (Salmo gairdneri) treated with a model hepatotoxicant....

An assessment of environmentally related variation in the recruitment of the California Current stock of Pacific mackerel (Scomber japonicus) and its implications for management

Creator:: Parrish, Richard Henry
Abstract:: Long-term oceanographic and meteorological data were used to develop models that describe the observed variation in the recruitment of Pacific mackerel (Scomber japonicus) in the California Current region. The models that were found to best describe recruitment included both density-dependent factors and environmental factors. Models incorporating only density-dependent factors accounted...

DDT and reproductive success of bluebirds and house wrens in Northeastern Oregon

Creator:: McCluskey, D. Cal
Resource Type:: Masters Thesis

Sediment characteristics and the trophic status of four Oregon lakes

Creator:: Meyerhoff, Roger Dean
Abstract:: There is evidence that recent ecological changes in lakes and their watersheds can be detected from analysis of lake sediments. This study was initiated to correlate changes in some sediment characteristics of four Oregon lakes with past cultural developments of the lakes and their watersheds. The lakes chosen for this...

Effects of chlorinated biologically stabilized kraft mill effluent on the mortality and growth of Coho salmon

Creator:: Steil, Deborah L.
Abstract:: Ninety-six hour acute toxicity bioassays were employed to determine the tolerance of juvenile coho salmon to chlorinated stabilized kraft mill effluent (SKME). In addition the effect of chlorinated SKME on the growth of juvenile coho salmon in six and ten day experiments was studied. Results of the acute toxicity tests...
