摘要: 本文报道以牙齿生长发育及臼齿磨损度鉴定长尾黄鼠年龄的方法,探讨了长尾黄鼠年龄与休重、体长及繁殖力的相互关系。将824只黄鼠划分为5个年龄段,分析表明.除幼体组外,其他各组的体重、体长及繁殖力和产仔数均与年龄无关。

Abstract: The study of age determination and age structure of population of the suslik,Citellus undulatus,was carried out.Based on dental development and worn degree on the surface of molar teeth,the observations in 824 specimens, the suslik could be divided into 5 age groups I—V(Fig.2).By statistical comparison we found that except the youngs(I),there wasno relationship between the age and body weight,bodylength litter size.
