摘要
The perception and response of environmental temperatures are vital for the survival,fitness and reproduction of all animal species.As a critical variable that affects the rate and nature of all biological and chemical reactions of the body,temperature has dramatic effect on animal physiology and behaviors.Homeotherms such as mammals maintain a relatively constant core body temperature despite of ambient temperature;changes of body temperature of transgenic mice greatly affect their energy efficiency and life span(Clos et al,1993).However,Poikilotherms such as C.
