| Abstract | The Painted turtle (Chrysemys picta) is a widespread North American species, and its subspecies found in Ohio is the Midland Painted turtle (Chrysemys picta marginata). While it is generally a widespread species and less at risk than other freshwater turtle species, understanding different local populations of the species can help us better understand the species as a whole, as well as factors that may play a role in conserving other freshwater turtle species. I conducted a mark-recapture study over the course of two separate study periods to assess the Midland Painted population in Conrad Balliet Family Nature Preserve’s Pond, a local pond in Clark County, Ohio. Of the turtles recorded, 28 individual turtles were captured, and there was a 1.33:1 ratio of male turtles to female turtles and a 0.19:1 ratio of juveniles to adult turtles. Males tended to be in higher abundance in traps when there were few females and accounted for more recaptures than females. The estimated population size for the pond is 30 Midland Painted turtles. Males were smaller in size than females, in carapace length and width, plastron length and width, shell height, and weight. This information, and further studies on the pond’s population, can serve to inform conservation methods for this species and other applicable freshwater turtle species as is relevant. |
