摘要
本文所获达乌尔黄鼠均采自泰来县东方红林场、平洋乡、大兴乡和汤池乡.从所获标本中随机抽出样本97只,其中,雄鼠52只、雌鼠45只,共分3个年龄组.我们对其头骨、阴茎骨、胎仔数(即子宫斑数)、睾丸长轴和短轴分别进行了列表测量,从中找出其与年龄划分的相关性,从而有助于了解泰来地区达乌尔黄鼠的种群结构和繁殖指数,也可以为分类学的研究和年龄鉴定提供重要依据.
The Daur spermophiles studied in this psper were all gathered from the East -is -red Forestry Centre, Ping Yang Village, Daxing Village, Tangchi Village of Tailai County. 97 samples are taken out of the specimens gathered, among which 52 are male and 45 female, divided into three groups. We' ve measured their head bones, penis bones, foetus number, the long axis and short axis of the testis and arranged the results into tables so as to find out the interrelations of them with the age division. Therefore it helps people to know the species structure and index number of breed of the Daur spermophiles in Tailai County. And it may also provide an important basis for the study of taxology and age appraisal
