英文摘要	Sexual dimorphism between males and females is a common pattern observed in the natural world and has become one of the main focuses of evolutionary biology. Amphibian head size and shape are important factors that may influence food acquisition, but knowledge about the sexual differences between amphibian head size and shape is relatively scant. Here, intersexual differences in the head size and shape of Rana kukunoris, which is a high-elevation frog from the Qinghai-Tibet Plateau, were investigated. Significant differences were found in the head shape but not the head size between sexes. prey size and head size. However, these correlations disappeared when individual body size was controlled, suggesting that body size but not food size was the main factor resulting in intersexual differences in head size/shape. The results suggested sexual dimorphism of head shape among these frogs.
