摘要
地理变异是蛇类中较为常见的现象。颈槽蛇Rhabdophis nuchalis在中国具有广泛的地理分布,是研究地理变异的理想物种。统计分析采自中国各地的61号颈槽蛇标本外部形态特征,对其地理变异模式进行了研究。结果表明:来自云南省高黎贡山的种群与其他种群在眶后鳞数、腹鳞数、上唇鳞黑纹的数量和后颔片间是否有小鳞等形态特征上的差异有统计学意义。
Geographic variation (GV) is widely spread in snakes. Rhabdophis nuchalis, which is one of the colubrid snakes with broadly geographical distribution in China, provides ideal taxa to explore GV. Based on multivariate statistical analyses of external morphological characters recorded from 61 specimens of China, we examined GV patterns for this species. The results showed that the specimens from Gaoligong Mountains were significantly different from those from other populations in the number of postocular scales, ventral scales, black stripes in the supralabial and the small scales between the posterior chin-shields.
