| Abstract |
|
The reproductive ecology of Terrapene carolina carolina (Eastern Box Turtle) was studied in an 11-ha woods in Lynchburg, VA. Estimated population demographics included a population size of 176 turtles with a 1:1 male to female sex ratio, population density of 16 turtles/ha, mean clutch size of 3.15 eggs, and a proportion of adult females gravid per year of 0.405. Reproductive output was 112 eggs per year. A positive significant relationship existed between female carapace width and clutch size, as well as female shell height and clutch size. However, no significant relationship existed between female carapace length (CL) and clutch size. When mean clutch size was compared to those of other investigators of T. c. carolina, a slight positive correlation with latitude was indicated, though it was not statistically significant. Mean female CL and clutch size in a Long Island population were both significantly larger than the means from the Virginia population.
