通过对采集于巴拿马运河区巴罗科罗拉多岛的512只鬣蜥的胃进行3个时期的观察,研究了鬣蜥Anolis limifrons的季节性食性。频率和长度的猎物和捕食者的长度进行了测定。从落叶层和低植被样品中获得不同大小类的潜在猎物的频率分布。蜥蜴会选择体型较大的潜在猎物。所有大小类的捕食者捕获较小的猎物,但较大的猎物采取了较大的捕食者。雌性蜥蜴比雄性蜥蜴胃里有更多的食物。在胃中发现的食物的频率没有湿季-旱季差异。
The seasonal food habits of Anolis limifrons, an iguanid lizard, were studied by examining the stomachs of 512 individuals collected on Barro Colorado Island, Panama Canal Zone, during three periods. Frequency and length of prey and length of predators were determined. Frequency distributions of different size classes of potential prey were obtained from leaf litter and low vegetation samples. The lizards selected larger size classes of potential prey. All size classes of predators captured the smaller size classes of prey, but the larger prey were taken by larger predators. More female than male lizards had food in their stomachs. There was no wet season—dry season difference in frequency of food found in the stomachs.
