摘　　要：为了分析和比较怀孕和断尾对雌性黑龙江草蜥(Takydromus amurensis)体温选择的影响,于2012年6月和8月,通过野外捕捉和实验室饲养的方法,对黑龙江省尚志市和辽宁省宽甸县的2个黑龙江草蜥种群进行体温调节实验。结果表明:在外界环境温度较低的情况下(20℃),黑龙江草蜥可以自行通过热源来进行体温调节;非妊娠期,雌性黑龙江草蜥的平均体温为(32.49±0.705)℃,妊娠期时,雌性黑龙江草蜥的平均体温为(33.90±0.674)℃,即怀孕后雌性黑龙江草蜥的体温明显升高(F1,61=65.600,P<0.001)。不论在妊娠期还是在非妊娠期,黑龙江草蜥尚志种群雌性的平均体温(33.39±0.909)℃明显高于宽甸种群雌性的平均体温(32.91±1.021)℃,这说明纬度较高地区的种群,体温调节的能力较强。断尾后,宽甸种群雌性的平均体温为(31.94±0.590)℃,尚志种群雌性的平均体温为(31.60±1.268)℃,两个种群的平均体温差异不显著(F1,18=0.591,P>0.05),但显著低于完整尾个体的平均体温(F1,18=9.854,P<0.05),表明尾部对体温调节具有一定作用。In order to analysis and compare the effect of pregnancy and amputation of tail on temperature choice in the female of Takydromus amurensis, the study was conducted in June and August of 2012. Two populations of Takydromus amurensis respectively from Shangzhi （Heilongjiang Province） and Kuandian （Liaoning Province） were studied by the method of field capturing and laboratory feeding. Our results showed that the Heilongjiang population of T. amurensis could make their own body temperature increase through the heat source thermostat, when the temperature of the external environment was low （20℃）. The mean temperature of the females were （32.49±0.705）℃ in the non-gestation period. However, in the pregnancy period, the mean temperature of the females were （33.90±0.674）℃, they were significantly higher after the pregnancy （F1,16=65.600, P〈0.℃001）. No matter the pregnancy period or the non-gestation period, the mean temperature of the females T. amurensis from Shangzhi （33.39 ± 0.909）℃ were significantly higher than the females from Kuandian （32.91 ±1.021）℃higher latitude. The mean temperature of the females from Kuandian were（31.91±1.021）℃.It showed that the ability of thermoregulatory was stronger in the area of 94±0.590）℃, and that fromShangzhi were （31.60 ± 1.268）℃ after amputation of tail. The difference was not obvious between the two populations （F1,18=0.591, P〉0.05）, but the mean temperature was obviously lower than the individual which has the complete tail （F1,18=9.854, P〈0.05）. The results showed that tail has influence on the thermoregulatory.
