板齿鼠肥满度季节变化的特征分析

Seasonal change of relative fatness of Bandicota indica

目的阐明不同性别、年龄组板齿鼠肥满度的变化以及季节差异。方法计算肥满度和差异性检验。结果板齿鼠的平均肥满度为(2.96±0.60)g/cm3,两性间肥满度差异极显著。结论对板齿鼠肥满度进行研究,可揭示其种群生态学方面的规律。

Objective To understand the relative fatness of Bandicota indica. Methods The fatness was calcu- lated and analyzed the remarkable difference. Results The results showed that the average relative fatness of Bandicota indica was （2.96 ＋ 0.60） g/cm3. The differences of relative fatness between the males and females were significant. Conclusion The analysis of relative fatness of Bandicota indica would be helpful in unveiling the law of population ecology.
