Ontogenetic Shifts of Morphology and Food Habits in the Oriental Garden Lizard, Calotes versicolor ( Aga midae) QIU Qing2Bo MA Xiao2Mei J I Xiang ( School of Life Sciences, Hangzhou Normal College, Hangzhou 310036, China) Abstract : Males and females of the oriental garden lizard ( Calotes versicolor) from a population in Tong2 shi, Hainan, southern China, differ in head size at hatchlings, with males having larger heads than fe2 males. This sexual dimorphism is slightly more pro2 nounced in adults than in hatchlings. Embryos of C1 versicolor allocate relatively more resources to the growth of ecologically significant morphological charac2 ters than do characters less directly tied to early survival and growth of hatchlings. As a consequence of this al2 location pattern, hatchlings have larger heads but shorter tails relative to snout2vent length (SVL) than do juveniles and adults. Adults do not show a sexual di2 morphism in SVL, but male adults attain longer tails than do female ones at the same SVL. An isometric growth pattern with SVL s increase is showed in the head length of both sexes and the head width of females during ontogeny. However, an allometric growth pat2 tern with SVL s increase is showed in the head width of males, which the growth rate becomes increasingly fast with the ontogeny. The food niche width and overlap differ in the different age and sex groups to a certain ex2 tent. However, no direct evidence has been found to show a noticeable contribution of the divergence in head size to the food niche segregation between males and fe2 males.
