Abstract |
Kinosternon scorpioides Sexual dimorphism of a population of the turtle Kinosternon scorpioides was evaluated at Palo Verde National Park, Costa Rica. Curved width (C.W.) and curved length (C.L.) of carapace, straight length of plastron (L.S.P.) and weight were measured in the dry season. Average (ñ standard deviation) C.L. was similar in both sexes: 18.72 ñ 1.16 cm (males) and 18.84 ñ 0.79 cm (females). Average C.W. for males and females was 18.83 ñ 1.39 cm and 20.90 ñ 0.94 cm respectively (P ó 0.05). Average L.S.P. was 15.43 ñ 1.09 cm (male) and 16.2 ñ 0.84 cm (females, P ó 0.05). Average weight was 611.4 ñ 103.4 g (males) and 755.8 ñ 113.3 g (females, P ó 0.05). Additionally, carapace and plastron morphometry, size, pigmentation of head, tail length, concavity of plastron and development of the beack (upper jaw) differed between sexes. Sexual dimorphism of C.W. and weight suggests sex related selective pressure Added by: Admin Last edited by: Beate Pfau |
