Maximal metabolic rate in Apodemus chevrieri born in current year
当年生高山姬鼠最大代谢率

The cold-induced Maximal Metabolic Rate(MMR) and locomotion-induced MMR of Apodemus Chevrieri born in current year and in past years are measured with the open-respiratory analyzer. Cold-induced MMR and locomotion-induced MMR of Apodemus Chevrieri born in current year are (7.25±0.25)mLO2/(g?h) and (9.22±0.27)mLO2/(g?h) respectively.There was no significant difference between males and females in cold-induced MMR, whereas locomotion-induced MMR in males was higher than females obviously. Cold-induced MMR of animals born in current year was lower than those born in past years, but Locomotion-induced MMR is the opposite. The results suggested that: the cold-induced MMR of males and females born in current year are almost the same, but lower than those born in past years because of the adaptation to the lower annual average temperature in Heng-duan mountain region. Locomotion-induced MMR in males was higher than that in females, it is possibly the result of long time adaptation in natural dispersing process after maturation to avoid inbreeding and competition.
