Wild turkey population dynamics in southwestern Wisconsin
Article Abstract:
Wild turkey populations may be affected by either-sex hunting, while severe winter weather can also reduce numbers. A new study investigates the population dynamics of a northern wild turkey population in Wisconsin over an eight-year period. Annual estimates of survival, reproduction and population size are combined with a stochastic population model to estimate the population's finite rate of increase. The model suggests that wild turkey recruitment in southwestern Wisconsin between 1989 and 1992 was insufficient to maintain wild turkey numbers, with unfavourable weather being one of the influencing factors.

Survival of wild turkey hens in southwestern Wisconsin
Article Abstract:
Predators caused the biggest mortality of wild turkey hen in the experimental management zone in western Vernon County, Wisconsin. Predators were either canids or avians and predation occurred mostly during nesting and rearing periods. Spring harvest were within regulation, while most causes of losses during recruitment were not established. The survival rate and causes of mortality in the study area are similar to other areas previously studied. Deep snow and cold temperatures can cause significant loss, especially when food sources are scarce.

Reproductive ecology of eastern wild turkeys in southwestern Wisconsin
Article Abstract:
The population dynamics of wild turkeys must be understood if sound harvesting strategies are to be developed. A new study investigates the reproductive ecology of wild turkeys in western Wisconsin during a four-year period. It is shown that reproductive success for adults is higher than subadults, although no age factors were evident for renesting rates. The main factor affecting nest success was mammalian predation. It is suggested that more conservative harvest levels are required to ensure population viability.
