Factors Affecting the Number of Fetuses in a White-tailed Deer Herd

Data were taken on 1,103 pregnant white-tailed deer (Odocoileus virginianus) harvested from the Savannah River Plant in South Carolina from 1965-1985 to describe temporal, age specific, and habitat effects on fetal number. Time periods were thought to represent periods of high and low population density. Age was the most significant factor in altering fetal number both with and without the data from the fawns included. Low fetal numbers per doe in 0.5- and 1.5-year-old deer and a high incidence of twinning in the older deer was responsible for this effect. Mean number of fetuses per doe...

Age, Condition, and Genetic Effects on Incidence of Spike Bucks

Data were taken from 3,721 male white-tailed deer (Odocoileus virginianus) harvested from the Savannah River Plant in South Carolina for the years 1977 to 1982 to document the incidence of spike bucks relative to habitat differences, harvest methodology, body weight, condition, and genetic variability. Of the 1.5-year-old bucks harvested, 33.1% had spike antlers. The incidence of spike or non-spike antlers was significantly correlated with age (r =0.29) and body weight (r =0.37). Significant differences in the incidence of spike bucks were observed between swamp and upland habitat types....

Reproductive Patterns, Productivity And Genetic Variability In Adjacent White-Tailed Deer Populations

White-tailed deer (Odocoileus virginianus) were collected from swamp and upland areas on the Savannah River Plant in South Carolina; the genetic variability of females was 9.8 and 8.5%, respectively, for the 2 areas. Reproductive rates (92-93 fawns/ 100 females) were essentially the same in the 2 areas. Deer in both populations, age> 2 yr, bred earlier and showed less variance in conception dates than younger deer, and swamp deer bred earlier than upland deer. In the swamp. deer with 2 fetuses had significantly higher levels of genetic variability than those with I fetus, and the trend...

Prenatal Selection In White-Tailed Deer

White-tailed deer (Odocoileus virginianus) (N = 1341) were collected from 7 locations in Georgia and South Carolina. Sorbitol dehydrogenase (SDH) activity was analyzed using starch-gel electrophoresis. Four types of prenatal selection, Female Gametic Selection, Random Mating, Male Reproductive Selection and Female Sexual Selection, were analyzed for this locus using genotype frequency data including mothers and offspring. Spatial and temporal heterog;eneity were analyzed for the Savannah River Plant (SRP) herd. Pooled genotype frequencies for SDH were essentially the same over 3 years but...

Starch Gel Electrophoresis for the Study of Population Genetics in White-Tailed Deer

Methods for the collection, preparation and extraction of tissues of white-tailed deer (Odocoileus drginianus) are given, Electrophoretic technique, buffers, gel preparation and banding patterns for 27 proteins encoded by 28 stnlctura) loci are described. In a survey of 400 deer from the Savannah River Plant, nine loci were shown to be polymorphic. The potential use ofpopulation genetics information for wildlife management programs is discussed.
