微尾鼩冬季肥满度的初步研究

Study on Relative Fatness of Anourosorex squamipes in Winter

对野外捕获 2 2 2号微尾标本进行肥满度研究。结果表明 ,不同生境肥满度差异不显著 ,雌雄微尾肥满度之间无显著差异 ,不同年龄组间肥满度差异显著 ,未成年个体肥满度明显高于成年个体 ;冬季各月份肥满度与种群数量呈负相关 ,r =- 0 96 4 6 <0 ,P <0 0 1。

The relative fatness of Anourosorex squamipes in winter was studied during December, 2003 to February, 2004. The result showed that there were no significant differences between different habitats and sexual difference with respect to relative fatness. The relative fatness changed significantly in different age groups, and it was significantly higher in sub-adult individuals than that in adult ones. In winter, the monthly relative fatness negatively correlated with its monthly population size (r=-0.9646<0, P<0.01).
