Diel Activity Patterns of Adult Bobcats in Central Mississippi

We monitored 13 (6 female, 7 male) adult bobcats (Lynx rufus) using radiotelemetry and examined seasonal activity patterns using 9,217 observations from August 1989 - August 1990. Female bobcats were active 49% and males were active 60% of the diel period. Mean percentage activity during winter of males (x = 71%,SE = 4.0%) was greater (P < 0.01) than that of females (x + 44%, SE + 5%). Bobcats exhibited greatest activity during crepuscular and nocturnal periods. We detected a less defined bimodal crepuscular activity than previous studies. High diurnal activity makes bobcats susceptible...

Predation Rates on Wild Turkey Hens in a Hardwood Bottomland Forest and a Mixed Forest in Mississippi

Concern has arisen about effects of predation on wild turkey (Meleagris gallopavo) populations because of increases in predator abundance. We examined differences in canid (Canis spp.) and bobcat (Felis rufus) predation of adult wild turkey hens between a hardwood bottomland forest and a mixed forest in Mississippi. Daily mortality rate from canids and bobcats was higher on the hardwood bottomland forest (0.002) than on the mixed forest (0.0006), but overall daily survival rates were similar. A higher predation rate on the hardwood bottomland forest from large predators may have been...
