The Effects of Cold Acclimation on Thermogenesis in Tree Shrews (Tupaia belangeri)

The resting metabolic rate (RMR),maximal nonshivering thermogenesis (NSTmax),cold induced resting metabolic rate (CIRMR),body mass,body temperature of the tree shrews were measured.The results showed that the body mass and the capacity of heat production in the coldacclimated groups were higher,and body temperature was lower than that in the control.The increase of RMR and CIRMR during cold acclimation was the main pattern of heat production in tree shrews.
