WASSMER ET AL.: SOUTH-CENTRAL FLORIDA BOBCAT ECOLOGY they averaged more intensive use of it. Both sexes tended to use open canopy xeric pine-oak habitats less frequently than other natural habitats. Among man-modified habitats, adult males used improved pastures more heavily than did females, but the difference was not significant (U5,7 = 7,p > 0.05, 2-tailed). Most of such utilization involved crossing pastures at night when traveling between areas of natural vegetation. With the exception of semi-tame female F1 who was frequently located in the vicinity of the dwelling where she was fed, females were associated with man-occupied habitats less than males. Juveniles showed more intensive use of certain habitat types than did adults. For example, only one adult (M6) had a ratio over three for use of any habitat, whereas four out of the five juveniles had one or more ratios of habitat use ranging from 3.04 to 12.65. Two (M4, F5) of the four juveniles showed unusually intense association with man-occupied habitats. These were kittens of the semi-tame female, and their high use of the man-occupied category reflects visitations of the family group to the dwelling until the kittens were about 8 months of age. Although F6 was also a member of this litter, her relatively lower association with man-modified habitats is explained by the fact that she was the last of the three siblings captured and thus a greater proportion of the data on her movements was obtained when the young were older and less frequently accompanied the mother to the dwelling. Progulske (1982) presented data on habitat utilization by several bobcats in northeastern Florida. In his study area, habitats with medium to dense understories were utilized more than habitats with open understories, and bottomland hardwoods were the most preferred vegetation association. Bobcats tended to avoid meadows and other open man-modified habitats but not pine plantations, which comprised a small fraction (8%) of the study area. All known den sites of females with young in this study were in natural vegetation associations, usually thick patches of saw palmetto and dense shrub thickets. Winegarner (1985b) also recorded 1-month-old young going in and out of a gopher tortoise (Gophents polyphemus) burrow. Adults without young also preferred dense palmettos or shrubs for rest sites. In Louisiana, Hall (1973) also found a preference for heavy cover as rest sites. In the present study, offspring of females other than F1 apparently were not exposed to man-modified habitats until about 2 months of age, when they began following the mother to different rest areas within her range. Although radiotracking alone was seldom accurate enough to delineate the exact travel routes of individuals being monitored, a combination of radiotracking, tracking on foot, the placement of scats and scrapes, and occasional visual observations indicated that bobcats generally moved about their home ranges along firelanes, roads, footpaths, animal trails, or railroad tracks or followed natural openings through the vegetation rather than bushwacking through dense cover. For example, within the home range of
