摘　　要：用3个恒定温度(27、30、33℃)和波动温度(14.0～37.5℃)孵化山地麻蜥(Eremias brenchleyi)卵。结果表明,各温度处理下卵孵化成功率差异不显著,但温度对孵化期、孵出幼体表型特征及疾跑速度有显著影响;27、30℃和波动温度下孵出幼体的SVL、重量及躯干干重比33℃的要大,33℃孵出幼体的运动能力比其他3个温度处理弱。波动温度处理下山地麻蜥卵虽短期经历潜在致死的极端温度,但对孵化成功率、孵出幼体表型特征和运动表现均无负效应。Eggs of Eremias brenchleyi were incubated at three constant（27,30 and 33℃） and one naturally fluctuating temperatures to assess the influence of incubation temperature on hatching success,hatchling traits and locomotor performance.The duration of incubation and sprint speed differed considerably among temperature treatments,whereas hatching success did not.Hatchling incubated at 33℃ were smaller in SVL and lighter in body mass and carcass dry mass but lighter in residual yolk dry mass than those at 27,30℃ and fluctuating temperatures.Similarly,the sprint speed of the hatchlings from 33℃ were also smaller than those from 27,30℃ and fluctuating temperatures.Eggs incubated at the fluctuating temperatures may experience extreme temperatures for brief periods,however,these temperatures does not have detectable adverse effects on hatching success,hatchlings phenotypic traits and sprint speed in E.brenchleyi.
