Statistically significant differences were found in body length, body weight and clutch size between three southern Michigan populations of the painted turtle (Chrysemys picta) occupying differing habitats. The clutch size differences were as great as those reported from different parts of the range of this and other species. Diet, rather than body weight or shell length, is suggested as being the factor responsible for observed differences in reproductive potential.
