Abstract: From November to December, 2010, the selected body temperature (T_sel), critical thermal maximum (T_CTMax), the diel variation in body temperature,post-prandial selected body temperature of Japalura splendida were measured under laboratory conditions. The T_sel and T_CTMax of J. splendida were (26.22±0.65) ℃ and (42.35±0.41) ℃, respectively. In a gradient of 15~30 ℃, the body temperature (T_b) was positively correlated with ambient temperature (T_e): T_b=0.663T_e+7.193. In the environment without thermal gradients, diel variation in body temperature was not significantly affected by environment temperatures (T₁₁=0.643,P=0.534). There were no significant differences in T_sel between fasted and fed lizards(F_{2, 104}=0.997, P=0.372). The results indicated that:(1)The body temperature of J.splendida changed with environment temperature. (2)J. splendida could conduct its body temperature by physiological thermoregulation. (3) The diffences of T_CTMax among J. splendida and other lizards may be related to their geographical distribution. (4)T_sel of J. splendida did not vary significantly between fasted and fed, while may be related to its food.

Key words: Japalura splendida, thermoregulation, selected body temperature, critical thermal maximum
