To study daily rhythms of body temperature, metabolic rates and evaporative water loss of Tupaia belangeri, we took measurements on body temperature (Tb) for 24 h by implanting thermometer into their body. We also measured rest metabolic rate (RMR), nonshivering thermogenesis (NST) and evaporative water loss (EWL) in 4 periods of 05:00-07:00, 11:00-13:00, 17:00-19:00 and 23:00-01:00 within 24 h. The body temperature showed a change in circadian rhythm with a maximum and minimum value of 39.45±0.26℃ and 36.34±0.24℃ at 11:00 and 03:00, respectively. The value of NST, RMR and EWL taken in the four periods within 24 h also significantly varied and exhibited a circadian rhythm. The minimum value of RMR_TNZ was 2.28±0.09 ml/(g·h) at 11:00-13:00 and maximum value was 2.58±0.04 ml/(g·h) occurred at 23:00-01:00; the highest value of NST occurred at 05:00-07:00 valued at 3.08±0.14 ml/(g·h) and the lowest value was 2.69±0.06 ml/(g·h) exhibited at period of 11:00-13:00; The maximum value of EWL was taken at 17:00-19:00 with 3.60±0.31 mg/(g·h). The body temperature variation was varied with change of ambient temperature and with the activeness of the animal in the different period in the 24 h rhythm. The RMR and NST was increase in the night when the ambient temperature was decrease. The animal adjusted their body temperature by increasing EWL in the day.
