| 摘 要： | 基于113个标本的吻肛长频次数据,初步划分吐鲁番沙虎(Teratoscincus roborowskii)的年龄组,各年龄组共选取54例个体,分别截取第2右前趾骨第3趾节,用常规石蜡切片法进行了骨龄学鉴定。同时,根据野外标记重捕方法获得个体的形态学生长指标来验证年龄组划分的合理性。结果表明,吐鲁番沙虎雌雄个体间吻肛长差异不显著,可以合并进行年龄鉴定;吐鲁番沙虎的吻肛长和骨龄间有显著的相关性;对于小于6龄的个体,骨龄学的方法适用于吐鲁番沙虎年龄的鉴定。

| Abstract: | Based on snout-vent length ( SVL) frequency data 113 specimens of Teratoscincus roborowskii were preliminarily divided into six age classes. Then,age determination was evaluated by skeletochronology of 54 samples of the 3rd section on the 2nd fore-right phalanges selected from the six age classes. The result of age determination was evaluated by individual growth index measured from mark-recapture samples. Results indicated that there was no significant difference in SVL between male and female individuals,... |
