摘要
本文以晶体干重法鉴定黄胸鼠的年龄,分析其种群年龄组成,并与其他年龄鉴定方法如体重法、体长法,臼齿磨损法进行了比较。
In this paper, the Buff-breasted rat Rattus flavipectus was collected from the Hangzhou city, Zhejiang province. We used the lens weight to divide 893 speciemens into 4 groups, juvenile, subadult, adult and senior. The age structures of the population in October, 1983 and 1988 were analysed. Several characters such as teeth wear, body weight and body length were also used to estimate the ages and were compared with lens weight.
