摘要
目的:通过研究花鼠的肥满度,为花鼠的监测和防治工作提供理论依据。方法:以M3颊齿的生长及磨损作为年龄划分的标准,划分出花鼠种群各年各月的年龄组成进行肥满度的研究。结果:花鼠的肥满度从亚成年组以后,随年龄的增长而增大。在年龄Ⅱ组和Ⅳ组中,肥满度均值在性别间的差异是十分显著的,而在年龄Ⅰ组和Ⅲ组中则差异不显著。结论:不同性别的花鼠肥满度随季节变化不同,在繁殖季节因产仔雌鼠肥满度低于雄鼠。
Objective To provide a theoretical basis for the monitoring and prevention of Eutamias sibiricus, it was studied of its fatness. Methods It was divided of the chipmunk population every year each month of age composition to study the fatness with the growth of M3 cheek teeth and wear as the standard age division. Results The fatness of the chipmunk fi＇om the sub adult group, increased with the age. In the age of Ⅱ group and Ⅳ group, the difference between the mean and the gender was significant, but there were no significant differences in I group and Ⅲ group. Conclusion There was a change of different sex chipmunk fatness in different seasons. However, during the breeding season, the fatness of female rats was litter than in the male rats.
