Effects of Temperature on Organ Masses and Digestive Tract Morphology in Apodemus chevrieri from Hengduan Mountain Region

In order to investigate the changes of plasticity of visceral organs and digestive tract morphology in Apodemus chevrieri which inhabit in Hengduan mountain region, the organ masses and digestive tract which include the changes of heart, lung, liver , spleen and kidney as well as the length and weight of stomach, small intestine, large intestine and cecum were measured during cold and warm acclimation. The results showed that the weight of heart and liver of cold acclimation group were obviously higher than that of warm acclimation group. The weight and length of small intestine showed significant differences between two groups. All of the results indicated that A. chevrieri maintain their normal life activities by increasing the weight of related organ masses and adjusting the weight and length of small intestine under cold temperature.
