Abstract

Copulation in South Dakota ornate box turtles (Terrapene ornata) was observed from April through September, with oviposition of 2–5 (  =  4.3) eggs in June. Growth was rapid during the first few years of life but slowed thereafter, with adult females attaining significantly larger (p < 0.001) carapace (  =  117.8 mm) and plastron (  =  123.9 mm) lengths (CL and PL, respectively) than did adult males ( CL  =  114.5 mm, PL  =  118.1 mm). Both sexes can mature by age nine, with our smallest adult female (CL  =  112.1 mm, PL  =  115.5 mm) larger than our smallest adult male (CL  =  107.9 mm, PL  =  110.4 mm).
