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(Lacertavivipara)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。In this paper,we study the effect of pregnancy on thermoregulation in the common lizard Lacerta vivipara population of Xiaoxing＇anling,Heilongjiang Province through the methods of wild capture and laboratory feeding in the June and September of 2008.The results show that the common lizard could make their own body temperature increase through the heat source thermostat under a low temperature （18℃）.Pregnancy affects a lot on the thermoregulation of Lacerta vivipara.Pregnant females,not like males and non-pregnant females increasing their temperatures to a high level （33℃ or so）,choose an appropriate temperature （31℃ or so）,which is the tradeoff between its own optimum temperature and optimum temperature for embryonic development.
