黄喉貂群体演化及环境适应机制

物种形成与适应性进化机制一直是进化生物学领域的研究焦点，而群体水平上的物种动态演化历程及不同生境下的适应机制研究是全面解析物种形成和适应性进化机制必不可少的组成部分。黄喉貂作为分布区纬度跨度大，适应不同生境海拔的中小型兽类，其群体演化历程及对不同环境的适应机制尚不明确。因此，对黄喉貂的研究有利于我们理解冰期循环与黄喉貂群体动态演化的作用关系，完善冰期循环对黄喉貂群体演化的影响及了解环境因子驱动的群体间表型适应的分子演化机制。本项目拟以黄喉貂为研究对象，通过基因组和群体基因组学的理论和方法，从微进化的角度探讨黄喉貂的群体演化动态和寒冷、高原环境下的适应性进化机制，以期为人们全面理解气候变迁背景下广布物种的群体演化动态及适应机制提供良好的研究范例，也为合理制定黄喉貂群体的科学保护与管理规划提供坚实的理论依据。

The mechanisms of speciation and adaptive evolution have been the focus of evolutionary biology for a long period of time. Exploring the dynamic evolution of certain populations and their adaptation mechanism under different habitats are essential parts in analyzing the mechanism of speciation and adaptive evolution comprehensively. Yellow-throated Marten (Martes flavigula) is a small to medium animal with distribution area of large latitude, which has adapted to different altitude habitats. However, its demographic history and the adaptation mechanism to different environments are still unclear. Therefore, the study on the Yellow-throated Marten is conducive for us to understand the relationship between glacial cycle and population dynamic evolution; make sense of the effect of glacial cycle on population evolution and comprehend the molecular evolution mechanism of inter-population phenotypic adaptation driven by environmental factors. The project plan todiscuss the dynamic group evolution of Yellow-throated Marten and mechanisms of adaptive evolution to cold and plateau environment through the theory and methods of genome and population genomics based on the perspective of micro evolution.. We hope to provide a good research example for people to fully understand the population evolution dynamics and adaptation mechanism of widespread species in the context of climate change. It can also provide a solid theoretical basis for scientific protection and management plan of Yellow-throated Marten.
