摘要
为探讨栖息于横断山地区高山姬鼠(Apodemus chevrieri)身体状况与环境之间的适应关系,对野外和实验室条件下高山姬鼠的身体能值进行了测定。结果表明,高山姬鼠身体能值存在季节性变化,6月最高,9月次之,11月开始下降,到次年3月达到最低。冷驯化条件下,其身体能值显著降低。高山姬鼠的身体能值在不同季节和冷驯化条件下表现出的变化模式,与其低纬度高海拔、年平均温度较低的生存环境有关,反映了横断山区小型哺乳动物在季节性环境中的生存机制和适应对策。
The energy contents of Apodemus chevrieri in field and in laboratory were measured. Our results showed that the body energy contents of A. chevrieri had seasonal variations.The energy contents were the largest in June, and the smallest in March. In cold-acclimation, the energy contents had significant decrease. The change pattern of the body energy contents in A. chevrieri was related to the macroenviroment such as low latitude, high elevation, and lower average ambient temperature. It had reflected survival mechanisms and the adaptive strategies of small mammals in Hengduan Mountainou Region.
