【Abstract】 Reproductive characteristics of seven grass lizard (Takydromus septentrionalis) populations from different geographic locations was compared by using cluster analysis with clutch size, egg size (egg length and egg width), egg mass and clutch mass as indices. The analysis indicates that the seven populations could be divided into two groups according to their reproductive characteristics. One group includes the lizard T.septentrionalis from Ningde county in Fujian Province, Dongtou Island and Lishui County in Zhejiang Province. The other one includes T.septentrionalis from Chuzhou County in Anhui Province, Beiji Island, Dongyang County and Hanghzou City in Zhejiang Province. Especially, the reproductive characteristics of the lizards from Beiji Island in Zhejiang Province is quite similar to those of the lizards from Chuzhou County in Anhui Province.更多还原
