横断山区大绒鼠生态分化及其对不同生态环境适应机制的研究

在生物进化过程中，对环境的适应是其重要的方面，而动物的生理生态特征是长期进化的结果。本研究拟采用基因组学、动物生理生态学和形态学方法，对横断山区大绒鼠的生态分化及适应机制等进行研究。研究内容包括（1）测定横断山不同地区大绒鼠不同种群的遗传多样性特征和遗传分化程度；（2）测定不同地区大绒鼠种群的表型分化及其与生态环境之间的关系；（3）测定不同地区大绒鼠对环境的适应机制。整合大绒鼠的基因组学、动物生理生态学和形态学特征，阐明大绒鼠对横断山区的适应对策；大绒鼠在不同的地理环境中是否出现表型分化或者生态分化，这些分化到底是环境影响较大，还是遗传差异所导致的。最终来深入理解和揭示大绒鼠对横断山区不同生态的环境的生存适应机理和进化意义。

In the process of biological evolution, adaptation to the environment is a necessary condition for evolution, the physiological and ecological characteristics of animals are the result of long-term evolution. This study intends to use genomics, animal physiological ecology and morphological methods, study ecological differentiation and its adaptation mechanism of Eothenomys miletus from Hengduan mountain region. The research contents include (1) determination the genetic diversities of characteristics and genetic differentiation of E. miletus in different regions; (2) determining the relationship between phenotypic differentiation and ecological environment in E. miletus from different areas; (3) determination of adaptation mechanism in different regions of E. miletus. The integration of genomics, animal physiological ecology and morphology, clarify the countermeasures to adapt to the Hengduan Mountains in E. miletus; whether E. miletus appeared phenotypic differentiation or ecological differentiation in the special geographical environment, the differentiation in the end is the environment influence, or caused by genetic differences. Finally to understand and reveal the survival adaptation mechanism and evolutionary significance of E. miletus from Hengduan mountain region.
