摘要
对捕获的150只鼢鼠亚科动物具有代表性的12个性状变异进行分析,结果表明体重变异系数最大,为32.37%,其次为眶间宽,变异系数为16.29%,颅基长的变异系数最小,仅为7.56%;测定的4个外部性状及8个头骨性状指标彼此之间都存在极显著正相关关系;甘肃鼢鼠与其他4种鼢鼠关系较远,单独聚为一类,斯氏鼢鼠与罗氏鼢鼠亲缘关系最近。
Twelve important morphological characters of Zokors in Gansu Province were measured and analyzed. The result showed that the variation in body weight was the greatest and its coefficient variation （CV） reached 32.37%. That in inter orbital width was the second and it＇s CV was 16.29%. The smallest variation was in the skull basilar length and it＇ s CV was 7.56 %. Four external characters significantly correlated with 8 skull characters. The distance sequence among 5 species showed as follows： the relation between M. cansus and the others was distant and M. smithi had the closest relation with M. rothschildi
