Orientation and homing of the brush rabbit

Creator:: Chapman, Joseph A.
Abstract:: A study of orientation and homing in brush rabbits, Sylvilagus bachmani ubericolor (Miller), was conducted on the E. E. Wilson Game Management Area 7 miles north of Corvallis, Oregon, between July 1967 and April 1969. Sixty-seven individual rabbits were fitted with radio-transmitters and returned to the field. Home ranges were...

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...

Dynamics of a population of mountain cottontail rabbits in central Oregon

Creator:: McKay, Donald Oren
Abstract:: Data from 186 mountain cottontail rabbits (Sylvilaus nuttallii) captured 455 times by livetrapping and from 46 rabbits collected by shooting were evaluated to determine monthly densities, survival rates, extent of movements, dispersion in relation to habitat types, and criteria for determining ages of mountain cottontails. Estimates of density computed for...

Changes in plasma cortisol concentration of juvenile salmonids during stress

Creator:: Strange, Richard Jackson
Abstract:: I investigated changes in plasma cortisol concentration over time in juvenile salmonids subjected to various stressors that might be encountered in their normal life cycle. This work was directed at finding a general indicator for stress in fish that could be used be used to aid fisheries research and management....

Resistance of coho salmon (Oncorhynchus kisutch) and steelhead trout (Salmo gairdneri) stocks and transferrin genotypes to bacterial kidney disease and vibriosis

Creator:: Winter, Gary Wayne
Abstract:: Juvenile coho salmon (Oncorhynchus kisutch) and steelhead trout (Salmo gairdneri) of different stocks and three transferrin genotypes (AA, AC, and CC), all reared in identical or similar environments, were experimentally infected with the causative agent of bacterial kidney disease (BKD) or Vibrio anguillarum. Mortality due to the pathogens was compared...

Racial identification of chinook salmon (Oncorhynchus tshawytscha) and juvenile steelhead trout (Salmo gairdneri)

Creator:: Martin, James T.
Abstract:: Efforts to manage stocks of salmonids in Pacific Northwest stream systems are complicated by the occurrence of several runs of a species thought to represent races rearing sympatrically as juveniles. In order to collect the population statistics needed to properly manage these stocks, managers need a method of identifying juvenile...
