摘要
目的探索板齿鼠种群年龄鉴定划分标准。方法对捕获的板齿鼠体重、体长、尾长、耳长和后足长测量统计。结果根据体重的频次划分,将板齿鼠划分成4个年龄组:幼年组(♂<159.0 g,♀<140.0g),亚成年组(♂∶159.0~290.9 g,♀∶140.0~289.9 g),成年Ⅰ组(♂∶291.0~389.9 g,♀∶290.0~409.9g),成年Ⅱ组(♂≥390.0 g,♀≥410.0 g)。结论体重法可用于板齿鼠的年龄鉴定。
Objective To study the age structure of Bandicota indica . Methods Measuring the body weight, body length, tail length, ear length, hind leg length of Bandicota indica. Results According to the frequency distribution of weight ,the Bandicota indica could be divided into four age groups :juvenile( ♂ 〈 159.0 g , ♀ 〈 140.0 g) , subaduh( ♂:159.0 -290.9 g, ♀: 140.0 -289.9 g) ,aduh ] ( ♂ :291.0 -389.9 g, ♀:290.0 -409.9 g) ,aduhH ( ♂ ≥ 390.0 g, ♀≥ 410.0 g). Conclusion The results show that the weighting method can be used as the identification of the age.
