| Abstract |
|
Sexual size dimorphism and the growth and maturation patterns were studied in the Mediterranean Spur-thighed Tortoise (Testudo g. graeca), in the central Jbilets mountains (western Morocco). The number and width of scute growth annuli were respectively used as indicators of age at sexual maturity and of juvenile growth rates. Males reach their sexual maturity earlier than females but juvenile growth rates do not differ between sexes. Thence, when reaching sexual maturity males are smaller than females. However, important age and size inter-individual variations were observed at maturity. In both sexes, precocious individuals show high juvenile growth rates but reach a smaller body size at maturity than late individuals. Therefore, sexual maturity depends on juvenile growth rates. The important individual variations in age and size at maturity could reflect the plasticity of individual growth and maturation in response to changing environmental conditions.
