摘要：

于2008年6月和9月，通过野外捕捉、实验室饲养的方法，对黑龙江省小兴安岭的胎生蜥蜴(Lacerta vivipara)种群进行研究，分析怀孕对雌性胎生蜥蜴体温选择的影响。结果表明：在较低的实验温度下(18℃)，胎生蜥蜴可以在热源下进行调温使自身的体温升高；怀孕对胎生蜥蜴的体温调节影响显著，但怀孕的雌性并没有像雄性和非怀孕期个体那样把体温调定到很高的温度(33℃左右)，而是选择了一个适当的温度(31℃左右)，这是胎生蜥蜴在自身最适温度和胚胎发育最适温度之间权衡的结果。

Abstract:

In this paper, we study the effect of pregnancy on thermoregulaton in the common lizard Lacerta vivipara population of Xiaoxing'anling, Heilongjiang Province through the methods of wild caught and laboratory rearing in June and September 2008. The results showed that the common lizard could make their own body temperature increased at low temperature (18℃) through the heat source thermostat. Pregnancy significantly affected on thermoregulation in the common in this study, while pregnant females not like the male and non-pregnant individuals to very high temperatures (33℃ or so) but chose an appropriate temperature (31℃ or so). The results from this study show that gravid females regulate their body temperatures trade-off between its own optimum temperature and optimum temperature for embryonic development.
