Abstract: The average daily metabolic rate (ADMR) of root voles ( Microtus oeconomus Pallas) were measured at several ambient temperatures(Ta), 10℃ -30℃ at the Research Station of Alpine Meadow Ecosystem at Menyuan, Qinghai (3200M elevation).Three measurements were taken during the year: Green up period (May), Exuberance period (July-Aug.) and Withering period (Sept. -Oct.).The results showed that the ADMR increased while the Ta decreased below 25℃ Ta . The ADMR was the highest in the Withering period (5.31mlO2/g·h) and the lowest in the Green upperiod(4.46mlO2/g·h).In the Exuberance period it was 4.58mlO2/g·h.The animals'average daily energy requirement estimated by ADMR was approximately 0.513kcal/g.day in the Green up period, 0.527 kcal/g·day in the Exuberance period, and 0.611 kcal/g.day in Withering period.

摘要: 结合中国科学院西北高原生物研究所的“高寒草甸生态系统的结构功能和生物生产力的研究”工作,我们于1983年5—10月,对海北定位站地区的小型啮齿动物——根田鼠的能量代谢进行了研究。
