Book excerpt: 本论文以分布于云南西部横断山地区的绒鼠和高山姬鼠为研究对象,从基因水平及个体表型水平进行研究,为该地区小型哺乳动物适应特征提供一些基础材料。云南剑川地区的绒鼠和高山姬鼠在基因水平上与其它地区的个体都存在显著差异,绒鼠种群之间基因流较弱。剑川地区的绒鼠应为E. fidelis,且可将其视为一独立的物种。绒鼠的遗传多样性小于姬鼠,这可能是绒鼠主要分布于横断山地区,而姬鼠分布更广的一个重要原因。不同地区高山姬鼠头骨形态和各器官比较中的差异与其生活习性,栖息生境等因素有关,且横断山地区海拔高度的垂直变化中氧压的变化对动物的适应有重要影响。为了更好的适应横断山地区特殊的环境特征,剑川地区的该两种动物都出现了比分类地位相近的物种消化能低,消化率高,推测此两种动物通过较高的能量吸收率来获得消化能以维持较高的代谢率水平,有利于对低纬度高海拔地区环境的适应。
