Comparison of trapping effort on unburned and burned sandhills, where TN is the total number of trapnights and trapping effort is expressed as trapnights/capture/ha.

All mice were captured four or more times on grids. I calculated the home range area using the Exclusive Boundary Strip Method, in which a boundary is plotted as half the distance between adjacent traps (Stickel 1954). Home range data are summarized in Tables 3 and 4. Three animals were marked on the grids as juveniles (gray pelage) and died or dispersed off the grid at approximately 60 days of age. Two more animals (female 26 and male 54 at Smith Lake) marked as juveniles did not leave the grid. The male shifted his home range, but I could not distinguish between juvenile and adult home ranges for female 26, who subsequently appeared to have an activity area larger than that of other females. Generally, ranges of males and females overlapped, but ranges of adult females did not (except occasionally with juveniles or young adults), a pattern which suggests intra-sexual territoriality (Kaufmann 1983). A female juvenile overlapped with the ranges of an adult of each sex. Female 26, the one with the unusually large range, overlapped somewhat with another adult female in September 1987. Seventeen adults trapped on the Smith Lake grid and one Anderson-Cue grid had an average home range of 804 m2. In general, males (mean = 910 m2) appeared to have larger home ranges than females (mean = 683 m2), but the difference was not significant (Mann-Whitney test atp = 0.01). I also estimated home ranges of adults trapped more than four times in a year at burrows on Anderson-Cue and Smith Lake, using the exclusive boundary method (Stickel 1954) as I did for grids. The boundary was set as equal to half the distance between burrows, and for burrows on the perimeter of the study site, I plotted a boundary of 10 m (a conservative estimate of distance moved beyond the burrow). All capture points were weighted equally, but in a few instances I omitted points that suggested unusual forays outside the usual home range of the animal.
