A study of the life history, population dynamics, and ecological relationships of the Columbian white-tailed deer (Odocoileus virginiarius leucurus) was conducted on the
Washington mainland, Columbian White-tailed Deer National Wildlife Refuge during 1972-1973 to provide information for management of this endangered subspecies. A total of 18,077 observations of deer recorded...
Within A rtemisia tridentata ssp. wyomingensis Nutt. (Wyoming big sagebrush)
communities of the Great Basin, lands dominated by the exotic annual grass Bromus
tectorum L. (cheatgrass) are increasing at an alarming rate. Carbon applications, which
reduce plant-available soil N, have been suggested as a way to give native vegetation a...
The specific objectives of the study were to determine the
sociological and economic considerations of the private landowners
and managers in Grant County, Oregon regarding their tolerances
of mule deer (Odocoileus hemionus)and deer hunters on their properties,
determine the attitudes of hunters who hunted deer in Grant
County in 1973...
Sagebrush steppe ecosystems are one of the most widespread but endangered ecosystems in North America. A diverse array of human-related stressors has gradually compromised these ecosystems' resilience to disturbance and invasion by Bromus tectorum (cheatgrass). The role of the foundational shrub Artemisia as a driver of herbaceous community structure and...
Transferrin of Columbian black-tailed deer (Odocoileus
hemionus columbianus) displayed two types of polymorphism. One
type involved differences in sialic acid content. The nature of the
other polymorphism is not known. A hypothesis for three codominant
alleles at a common locus was proposed and tested by using the
Hardy-Weinberg Principle. The...
Relative use by pronghorns (Antilocapra americana) of 16 range sites was studied during summer and fall of 1971 and 1972 on Hart Mountain National Antelope Refuge, an area of high desert
rangeland in south central Oregon. A Relative Use Index was developed based upon 1533 observations of pronghorns located on...
Concentrations of selenium (Se), manganese (Mn), zinc (Zn), cadmium (Cd), lead (Pb) and arsenic (As) were measured in the water column, sediment and biota, in conjunction with selected physicochemical data, from representative wetland types at a mining site within Salt Lake County, Utah, USA. The selected field sites included Oolitic...
The purpose of this study was to characterize glenohumeral joint laxity and
stiffness using instrumented arthrometry. To evaluate the validity of an instrumented
measurement system we compared cutaneous and bone-pinned measures of laxity and
stiffness that replicate previously reported in vivo methodology. Characterization of
capsular laxity was achieved through determination...
Objective: To determine the effectiveness of moderate pre-exercise warm-up, static stretching, or a combination of both on muscular force production and hamstring extensibility of the lower extremity. Design and Setting: This experiment was a counterbalanced repeated measures design of four treatment conditions. Subjects participated in warm-up, static stretching, combined warm-up...
The semi-parametric approach to the analysis of proportional hazards survival data
is relatively new, having been initiated in 1972 by Sir David Cox, who restricted its use
to hypothesis tests and confidence intervals for fixed effects in a regression setting.
Practitioners have begun to diversify applications of this model, constructing...
