Impact of Hunting Pressure on Adult Male White-tailed Deer Behavior

Hunting pressure can lead to drastic changes in white-tailed deer (Odocoileus virginianus) behavior, though previous studies have focused mainly on females and juvenile males. Adult male white-tailed deer have not been studied in the context of hunting pressure since the advent of GPS technology. During 2006-2007, we deployed GPS collars on nine adult (≥2.5 years old) male white-tailed deer to examine changes in home range (95% fixed kernel) and core area (50% fixed kernel) size, shifts in home range and core area, movement, activity, and vulnerability to harvest during Maryland's two-week...

Effects of GPS Sampling Intensity on Home Range Analyses

The two most common methods for determining home ranges, minimum convex polygon (MCP) and kernel analyses, can be affected by sampling intensity. Despite prior research, it remains unclear how high-intensity sampling regimes affect home range estimations. We used datasets from 14 GPS-collared, white-tailed deer (Odocoileus virginianus) to describe the size and location accuracy of home range estimates calculated from different sampling regimes. We compared monthly home range estimates from seven sub-samples (480, 360, 180, 90, 60, 30, and 15 locations) to the home range estimates of...

White-tailed Deer Use of Clover Patches and Soybean Fields in an Agricultural Area

To effectively manage a white-tailed deer (Odocoileus virginianus) population in an agricultural area, information regarding habitat use and selection is needed to aid in reducing crop damage. We gathered data on deer use of clover (Trifolium repens) and soybean (Glycine max [L.]) fields at Chesapeake Farms, Maryland. We surveyed soybean and clover fields to test the hypothesis that deer distribute themselves proportionally to availability of soybeans and clover fields. Clover patch height and mass were also measured to quantify the amount of use by deer. Deer density in clover fields was...
