摘 要 ：研究变色树蜥（Calotes versicolor）的选择体温、热耐受性、温度对食物同化的影响。结果显示：① 幼体的选择体温、临界高温和临界低温的平均值分别为32.6、41.7℃和 7.7℃；成体的选择体温、临界高温和临界低温的平均值分别为33.1、42.0℃和8.2℃。② 环境温度在26~34℃时，对变色树蜥食物通过时间和摄入能有显著的影响；对表观消化系数（ADC）和同化效率（AE）无显著的影响；在28~34℃时食物通过时间随温度升高而缩短；在26、28℃和30℃时，摄入能小于更高温度的对应值。

Abstract:Selected body temperature (Tsel), critical thermal minimum (CTMin), critical thermal maximum (CTMax), and influence of temperature on food assimilation were studied in the Oriental Garden Lizard, Calotes versicolor (Agamidae), from a population in Wuzhishan, Hainan, southern China. Tsel, CTMin and CTMax of juveniles averaged 32.6, 7.7℃ and 41.7℃, respectively. Tsel, CTMin and CTMax of adults averaged 33.1, 8.2℃ and 42.0℃, respectively. Temperature significantly affected food passage time, energy intake but not apparent digestive coefficient (ADC), assimilation efficiency (AE) of lizards. The food passage time decreased with increase in temperature from 28 to 34℃. Energy intake was lower at 26, 28 and 30℃ than at higher temperatures.
