Cryo-preservation of viable fish sperm

Creator:: Graybill, James Roger
Abstract:: Fishery researchers have attempted to preserve viable fish sperm for extended periods of time. Only limited success has been achieved with storage of spermatozoa from salmonids. The principal accomplishments of this investigation during the fiscal year 1966-1967 were the development of standard methods for the collection and evaluation of fish...

Assemblages of groundfish caught using commercial fishing strategies off the coasts of Oregon and Washington from 1985-1987

Creator:: Rogers, Jean Beyer
Abstract:: The groundfish trawl fishery operating off the coasts of Oregon and Washington 1985-1987 caught six major assemblages of species which could be treated as units in developing mixed-species management plans. Eighty-one percent of the tows observed on commercial vessels were consistently placed in one of the assemblage designations using three...

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...

The reproductive biology of the mountain cottontail rabbit in Oregon

Creator:: Powers, Roger Alan
Abstract:: The reproductive characteristics of the mountain cottontail rabbit, Sylvilagus nuttalli (Bachman), were investigated from 269 specimens collected in central Oregon between 28 May 1968 and 28 August 1969. Male rabbits were in breeding condition between mid-February and 3 July 1969. Nearly 77% of the females bore four litters between 7...

Intraperitoneal implantation of life-long telemetry transmitters in otariids

Creator:: Horning, Markus, Haulena, Martin, Tuomi, Pamela A, and Mellish, Jo-Ann E.
Abstract:: Background: Pinnipeds, including many endangered and declining species, are inaccessible and difficult to monitor for extended periods using externally attached telemetry devices that are shed during the annual molt. Archival satellite transmitters were implanted intraperitoneally into four rehabilitated California sea lions (Zalophus californianus) and 15 wild juvenile Steller sea lions...

Development of a progeny marker for steelhead

Creator:: Shippentower, Gene E.
Abstract:: This study was undertaken to determine if strontium chloride could be used to create a trans-generational otolith mark in steelhead (Oncorhynchus mykiss). I completed two strontium injection trials and a survey of juvenile steelhead from various steelhead hatcheries. The two trials measured Sr:Ca ratios in otoliths in response to injections...

Relationships between fish species distribution and habitat in the Willamette River drainage in western Oregon

Creator:: Kruse, Amy Ellen
Abstract:: The objectives of this study were to (1) describe physical environmental conditions and species composition at several sites along an Upstream/downstream gradient in a number of tributaries of the Willamette River in western Oregon; and (2) identify possible relationships between species distributional patterns and physical habitat parameters using detrended correspondence...

Age-specific variation in apparent survival rates of male lesser-prairie-chickens

Creator:: Hagen, Christian A., Pitman, James C., Sandercock, Brett K., Robel, Robert J., and Applegate, Roger D.
Abstract:: We used mark-recapture methods to estimate age-specific apparent survival rates for male Lesser Prairie-Chickens (Tympanuchus pallidicinctus), a gamebird of conservation concern. A total of 311 male prairie-chickens (135 yearlings, 176 adults) were captured and banded during a 5-year study in southwest Kansas. Time-since-marking models were used to estimate apparent survival...

Lesser prairie-chicken brood habitat in sand sagebrush: invertebrate biomass and vegetation

Creator:: Hagen, Christian A., Salter, G. Curran, Pitman, James C., Robel, Robert J., and Applegate, Roger D.
Abstract:: Invertebrates are an important food source for grouse chicks, especially within the first 2 weeks of life. Invertebrate abundance is highly patchy and dependent upon herbaceous cover and vegetation structure. We examined the relationship between invertebrate biomass (from sweepnet samples) and habitat structure at lesser prairie-chicken (Tympanuchus pallidicinctus) brood-use and...
