摘要/Abstract

摘要： 2010年11-12月,测定丽纹攀蜥Japalura splendida实验室条件下的选择体温、临界高温、昼夜体温和摄食后的选择体温等热生物学指标。结果显示:丽纹攀蜥的选择体温T_sel和临界高温T_CTMax分别为(26.22±0.65) ℃和(42.35±0.41) ℃;在环境温度为15~35 ℃的实验条件下,丽纹攀蜥的体温T_b与环境温度T_e存在线性关系(T_b=0.663T_e+7.193;);在缺乏温度梯度热环境下,环境温度与丽纹攀蜥的活动体温差异不显著(T₁₁=0.643,P=0.534);摄食前后丽纹攀蜥的选择体温不存在显著差异(F_{2, 104}=0.997, P=0.372)。结果表明:(1)丽纹攀蜥的体温随环境温度的变化而变化,显示了外温动物的体温特点;(2)丽纹攀蜥具有一定的生理调节体温的能力;(3)丽纹攀蜥与其他蜥蜴在临界高温上的差异可能与其地理分布有关;(4)摄食前后丽纹攀蜥选择体温差异不显著可能与其摄入的食物有关。

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
