number, No is number of captures, Po is persistence on grid in days, A is area of the home range in m2 for
juveniles (Aj) and adults (AA).

 Seventy-one home ranges for 62 animals who fit the above criteria are shown in
Figure 3. Home ranges for adult males frequently overlapped, but those of females did not;
two Smith Lake females who appear to overlap in 1988 actually were separated temporally.
This separation of home ranges, similar to that observed on grids, suggests intra-sexual
territoriality. Home ranges varied in size from 210 m2 (for Smith Lake female 26, captured
at a single burrow 6 times in 1987) to 11007 m2 (for Smith Lake male 11 in 1986). The
average home range size for 35 females was 2601 m2 (SD = 1315.1) and for 40 males was
4042 m2 (SD = 2269.4); home ranges of the two sexes differed significantly (Mann-Whitney
U = 2.95, p = 0.01). For the Smith Lake data I also compared areas in 1983-1985 with
those of 1986-1988 to see whether home range size changed after the prescribed bum in
1985, but I found no significant difference.
 Capture data for 75 adults are shown on Table 5. Females 86, 94, and 97 (1987)
were from Anderson-Cue; the remaining animals were on Smith Lake. Each animal was
trapped from 5 to 22 times during the year in question, and almost all mice utilized more
than one burrow (mean number of burrows = 3.8). Estimates of persistence (the number of
days between first and last captures) are minimal estimates of persistence on the sandhill;
they are not comparable across years because trapping effort varied each year, nor do they
represent longevity because captures of juveniles and subadults (or captures as adults in
years other than those shown) are excluded.
