本研究拟以自然状态下的达乌尔鼠兔家群为研究对象，采用标志重捕和动物标签及无线电遥测跟踪方法，利用社群网络分析鼠兔家群的分群-聚群的社群行为模式；采用微卫星技术分析达乌尔鼠兔家群个体之间的遗传亲近度，分析野外条件下鼠兔家群成员间的亲缘关系对其社群行为与扩散模式的影响，从分子、个体和社群三个层面研究达乌尔鼠家群的社群网络结构与基因流在维持其家群遗传多样性的作用与机制。利用达乌尔鼠兔所具有的秋季集群储草习性，采用行为摄像技术研究和生态学调查测定各家群个体的秋季平均储草量。通过比较分析不同亲缘关系的达乌尔鼠兔家群的平均储草量大小的差异，结合各社群的亲缘关系来验证和揭示达乌尔鼠兔在群居性进化中的模式作用；从理论上为小哺乳动物群居性进化机制提供重要的依据。

The research is aim to study the Daurian pika family structure and its seasonal pattern through the Capture-Mark-Recapture method, to detect the individual relatedness by means of microsatellite DNA analysis, and to analyse the effect of the individual relatedness within Daurian pika colony on social behavior and dispersal, so as to illustrate the mechanism of social behavior and gene flow on maintaining the pika population genetic diversity at term of molecular, individual, population levels. We record Daurian pika behavior of caching food using camera in autumn, comparing the amount of hay piles and the weight of caching food among different relatedness colony, to reveal the role of relatedness in the evolution of sociality in Daurian pika population, as well as to the small mammals.
