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...

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....

Forest Successional and Disturbance Dynamics in the Southern Blue Mountains of Eastern Oregon

Creator:: Johnston, James D.
Abstract:: The application of modern land management practices beginning at the turn of the 20th century is widely believed to have dramatically transformed forest landscapes of the inland Pacific Northwest. Restoring historical conditions to make forests resilient to future climate and disturbance regimes is a major goal of federal forest managers....

The ascorbic acid requirements of older adolescents

Creator:: Davey, Bessie Louise
Abstract:: The concentration of ascorbic acid in the plasma was determined on four levels of ascorbic acid intake for seven day periods in 1946-47 and on three levels of ascorbic acid intake for ten day periods in 1947-48. The subjects, eight girls and eight boys, were 16 to 19 year old...

Effectiveness of a fluidized bed in filtration of airborne particulate of submicron size

Creator:: Black, Charles Hartgraves
Abstract:: Submicron particulate (mean size of 0.52 microns) was filtered from air at substantially atmospheric temperature and pressure by passing air up through a bed of fluidized glass shot in a two inch column. Removal efficiency, defined as the percentage removal of particulate from the air stream, was essentially constant during...

Structural and functional dissection of the vaccinia virus thymidine kinase enzyme

Creator:: Black, Margaret E.
Abstract:: Thymidine kinase is a key enzyme in the nucleotide salvage pathway, catalyzing the production of dTMP from thymidine and ATP. In order to identify the structural features of the TK protein and/or primary amino acid sequences which contribute to the catalytic and regulatory activities of this enzyme, an in vitro...

Seasonal and short-term nitrogen cycling in Populus

Creator:: Black, Brent L.
Abstract:: Poplar Bark Storage Proteins (BSP) are important in storing nitrogen (N) recovered from autumn-senescent leaves, and supply N for spring growth. Plants of Populus tremula x P. alba were transformed with a poplar BSP antisense cDNA fused to a double 35S promoter. Regenerated lines were screened for reduced BSP accumulation...
