This thesis focuses upon whether stressful aspects of an organism's environment are reflected by that organism's shape. It presents an application of the powerful thin-plate spline and relative warp methods from morphometric analysis to demonstrate the overall utility of morphometrics in detecting environmental stress in an estuarine flatfish, the English...
Mimeographed copy of a report, presumably to the Oregon State Game Commission. Includes maps and original b+w photographs of Rogue River dams, fishways, and fishing in the late 1920s. The author was extremely frank about the issues of the day, particularly law enforcement issues.
This report consists of tables summarizing data regarding streams receiving hatchery-reared rainbow trout since 1952. It includes data such as sources, sizes of fish, and water temperatures at the planting sites. It also averages data from creel reports from 1965-1972.
The spatial and dynamic pattern of landscape changes has a profound effect on the supply of environmental services, including the provision of habitat for fish and wildlife. Spatial heterogeneity is a common feature of landscapes in the Pacific Northwest, most notably in areas important to the production of salmonid fish...
This document contains a result of a study to determine the role of hatchery-reared winter steelhead in steelhead fisheries. The study examines the contribution of these salmon ‘with respect to’ angling intensity, number of fish stocked, contribution of native stocks, and several other factors. It also investigates survival of hatchery-reared...
Much of the Columbia River Basin has been cultivated for agriculture, which has reduced and fragmented the native shrub-steppe habitats. As a result, the range of the Washington ground squirrel (Spermophilus washingtoni) has been significantly reduced, prompting the states of Washington and Oregon to review their status. Consequently, I investigated...
Ten species of bats occur in the Oregon Coast Range and are hypothesized to be
associated with late-successional forests. The development of characteristics of late-successional
forests in young forest stands can be accelerated through silvicultural
practices such as thinning I examined the effects of thinning on the use of forests...
