摘要
目的探索海南屋顶鼠种群年龄鉴定划分标准。方法对捕获的海南屋顶鼠体重、体长、尾长测量,采用t检验的方法对数据进行统计分析。结果通过研究可将海南屋顶鼠划分成4个年龄组:幼年组(Ⅰ)(<85.0g),亚成年组(Ⅱ)(85.0～124.9g),成年组(Ⅲ)(125.0～174.9g),老年组(Ⅳ)(175.0g以上),对比不同年龄组体重的变化,各年龄组之间差异极显著。结论体重法可用于海南屋顶鼠的年龄鉴定。统计学意义。
Objective To explore the age determination standard of Rattus rattus hainanus.Method Capturing the Rattus rattus hainanus and measuring the body weight,body length and tail length.The results carried out statistical analysis by t-test.Results According to weight frequency distribution,the Rattus rattus hainanus were divided into 4 age groups,they were juvenile group（85.0g）,subadult group（85.0-124.9g）,adult group（125.0~174.9g）,elder group（≥175.0g）,there were statistical significance between weights of different groups.Conclusions Body weight method was suitable for Rattus rattus hainanus age determination
