Postnatal Development of Thermoregulation in Altricial Mammals

CHI Qing-Sheng~(①②) WANG De-Hua~(①)(① Institute of Zoology,Chinese Academy of Sciences,Beijing 100080;② Graduate School of Chinese Academy of Sciences,Beijing 100049,China)  
Mammalian neonates can be divided into three categories,namely precocial,altricial,and immature,mainly according to their establishment of successful thermoregulation.The altricial mammals are often born naked with poor insulation and weak thermogenic abilities.So they cannot thermoregulate efficiently in their early lives.When ambient temperature falls below the thermal neutral zone,isolated young cannot maintain high constant body temperatures.However,the newborns can increase thermogenesis when cold exposed,which is different from poikilotherms.The altricial mammals often show careful parental care and the young can huddle together to prevent heat loss.Thus,even newborns can maintain their body temperatures at a relatively high level in the nest.The deficiency of physiological heat production in the early stages of altricial mammals can be regarded as advantageous for development because it can promote growth and development by decreasing the energy allocation to thermoregulation.Finally the possible research trends of this field are proposed.
