Mortality Patterns of Female White-tailed Deer in Southwest Florida

Eleven of 66 radio-collared white-tailed deer (Odocoileus virginianus) in southwest Florida were killed by bobcats (Felis rufus) and 4 by Florida panthers {Felis concolor coryi). Average doe home range size was 194 ha, and 2 bucks ranged from 454-1,560 ha. There were no differences (P = 0.336) in doe survival rates among seasons. The average annual survival rate for does was 0.813 (95% CI- 0.68, 0.94) and 64% of the annual mortality was attributable to predation. Average neonate mortality rate was 37.8% ±16.1 and appeared to increase with surface water levels. Human hunting activities had...


Day Beds, Natal Dens, and Activity of Florida Panthers

Day rest sites and natal dens of Florida panthers (Felis concolor coryi) studied from January 1986 to August 1989 were dominated by dense vegetation, especially saw palmetto (Serenoa repens). Activity peaked around sunrise and sunset for both denning females and solitary panthers; however, solitary panthers exhibited greater extremes in activity and inactivity. Females were most likely to be at the den during daylight and spent about 50% of the denning period at the den. Day beds and den sites are important habitat features and should be considerations in panther management.
