This study was conducted to delineate the cause or causes of
winter deaths in deer and to provide information from which emergency
feed could be formulated. Deer were shot at monthly intervals through
the winter in Wallowa County, Oregon. Samples from the rumen, liver,
mandible, blood and feces were taken...
Most of the nutritionally related difficulties of winter feeding
deer apparently result from either poor acceptability of artificial
rations or digestive disturbances that result from feeding starved
animals feeds to which they are not accustomed. Reported in this
thesis are studies conducted with both captive and wild deer concerning
acceptability...
Preliminary studies with a dog (Canis familiaris) and a coyote
(Canis latrans) showed that these carnivores can serve as definitive
hosts in the life cycle of Sarcocystis fusiformis of cattle (Bos
taurus) and a microscopic Sarcocystis of mule deer (Odocoileus
hemionus hemionus). Preliminary studies to determine effects of the
cervine...
An important segment of outdoor recreational activity in
eastern Oregon is based on the harvest of deer. The deer population
can be altered in two ways. Rangeland, which provides feed and
cover for deer, can be improved through public or private investments
or hunting regulations can be changed. This study...
Natality of black-tailed deer in McDonald State Forest was determined by examination of 147 reproductive tracts. Yearlings collected from November of 1968 to May of 1970 had an average of 0.79 corpora lutea per doe, and adults 1.76 corpora lutea per doe. Yearlings collected during the spring in 1969 and...
Field studies were conducted during January, February and March of
1976 and 1977 to evaluate the effects of a prescribed burning program on
mule deer at Lava Beds National Monument. Visual observation, radio-telemetry
and pellet-group plots were utilized to investigate deer distribution,
food habits, movement patterns and behavioral responses to...
Rates of defecation of black-tailed deer in the Tillamook Burn of western Oregon were estimated using counts of groups of fecal
pellets in 1959 and 1960. A 340-acre enclosure was divided into eight range types on the basis of depth of soil, aspect, and elevation. The estimated rates of defecation...
A population of Columbian white-tailed deer (CWTD) was studied on a
refuge (790 ha) in southwestern Washington during 1972-77. Quality of
habitat was considered good for these deer and total population size remained
between 164-230 as determined by mark-recapture methods during
November. Population size declined significantly between the winters of...
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...
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...
