摘要： 夏武平等(1963)以东北红背(鼠平)(Clethrionomys rutilus)为对象,首次提出用鱼类学上表示鱼类生活状况的肥满度应用于鼠类对环境适应情况的形态——生理指标,发现秋季肥满度对次年夏季种群数量有一定的影响;他们(1964)还对大林姬鼠(Apodemus speciosus peninsulae)进行了探讨。近来,秦耀亮(1981)对南方黄毛鼠(Rattus rattoides exiguus)肥满度进行了比较研究。
Abstract: From 1973-1980, a total of 3,571 house mice were captured from various habitats and of all seasons in Taxihe, Manas county, Xinjiang Uygur Autonomous Region. Measurements of length and weight of body were taken for studying the relative fatness of the mice.The auther calculated it by means of the following formula which was introduced into small mammal's investigation by Hsia et al (1963) from ichthological study:K= 100W/L3,where K represents the relative fatness, W the weight in gram, L the length of head and body in cm.The results show that the relative fatness of house mice has the following features :There are no obvious differences in sex or in various groups of age (Table1 ) .The difference of relative fatness between various habitats is evident especially in October (Table 2 ) .There are obvious seasonal fluctuations. It is medium in spring (K = 3.19), the lowest in summer (K = 3.11 ), the highest in the middle of october (K = 3.38 ), but before winter coming, it drops evidently and keeps the valus until next spring (K=3.14 ) (Table 3, Fig. 1 ) .
