摘    要:为探讨横断山区小型哺乳动物体温调节和产热特征的日节律,对横断山区固有种大绒鼠(Eothenomys mile-tus)在24h中4个时间段(05:00—07:00、11:00—13:00、17:00—19:00、23:00—01:00)的体温、基础代谢率、非颤抖性产热进行了测定。结果显示大绒鼠的体温、基础代谢率、非颤抖性产热在24h内具有节律性波动,且变化趋势基本同步;各生理参数的最高值和最低值都分别出现在05:00—07:00和11:00—13:00时间段。结果表明,横断山区大绒鼠的基础代谢率、非颤抖性产热在其体温调节的日节律中起到了重要作用,同时,大绒鼠其夜间体温调节、产热特征显著高于白天,以适应横断山日温差大、食物资源丰富的特征。

关 键 词:大绒鼠(Eothenomys  miletus)  体温调节  产热特征  日节律

Abstract:Eothenomys miletus is a small mammal inhabiting in Hengduan mountains region.To better understand daily rhythms of thermoregulatory and thermogenic properties in small mammals inhabiting in Hengduan mountains region,body temperature(Tb),nonshivering thermogenesis(NST),basal metabolic rate(BMR) were measured during courses of one day(05:00-07:00,11:00-13:00,17:00-19:00,and 23:00-01:00) in E.miletus.E.miletus manifested clear circadian rhythms of Tb,BMR,NST,and these oscillations were similar.Moreover,the max...
Keywords:Eothenomys miletus  thermoregulatory  thermogenic propertie  daily rhythms
