The feeding habits of the Mazama pocket gopher in the pine region of South-Central Oregon

Creator:: Burton, Douglas Harlow
Abstract:: The objective of this study was to determine the feeding habits of the Mazama pocket gopher (Thomomys mazama Merriam) in the pine region of south-central Oregon. Damage caused by pocket gophers to conifer regeneration was a major incentive for this research. A permanent reference collection, consisting of epithelial tissue from...

Relation of the northern pocket gopher to forest habitats in south-central Oregon

Creator:: Anderson, R. J.
Abstract:: Reduction of pocket gopher damage to conifer seedlings is important to successful reforestation in many regions of the Pacific Northwest. The objective of this study was to determine the factors that influence the local distribution of the northern pocket gopher (Thomomys talpoides Richardson) in a forested region of south-central Oregon....

The response of animals to herbicide-induced habitat changes

Creator:: Borrecco, John Edward
Abstract:: The objectives of this investigation were to examine the changes in vegetation resulting from application of herbicides, and to study the effects of these vegetative changes on the abundance and composition of small-mammal populations, and on deer usage of treated and untreated plots. Three areas in western Oregon were selected...

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 role of ascorbic acid on discoloration of strawberry juice and concentrate

Creator:: Poei, Metty Soek-Kioen
Abstract:: The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate. The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...

Analysis of waves in the near-field of wave energy converter arrays through image processing

Creator:: Black, Colleen
Abstract:: Oregon State University conducted a series of laboratory experiments to measure and quantify the near-field wave effects caused within arrays of Wave Energy Converters (WEC). As the waves and WECs interact, the WECs generate radiated waves; these effects vary with the location within the array. Analyzing the near-field waves will...

An analysis of a population of snowshoe hares, Lepus americanus washingtonii Baird, in western Oregon

Creator:: Black, Hugh C., 1941-
Abstract:: The ecology of a population of snowshoe hares, Lepus americanus washingtonii, was studied in western Oregon from 1960 to 1962. Objectives were to obtain information to control hares, which frequently cause damage to coniferous reproduction in the region, and to compare the life history of this little-studied subspecies with others....

The role of body size in the foraging strategies and management of avian herbivores : a comparison of dusky Canada geese (Branta canadensis occidentalis) and cackling geese (B. hutchinsii minima) wintering in the Willamette Valley of Oregon

Creator:: Mini, Anne E.
Abstract:: Body size explains much of the interspecific variation in the physiology, behavior, and morphology of birds, such as metabolic rate, diet selection, intake rate, gut size, and bill size. Based on mass-specific metabolic requirements and relative energetic costs of activities, being a certain body size has both advantages and disadvantages....
