第四纪冰期气候变化对北半球动物的影响及其机制是探讨动物演变的重要科学问题。综合运用分子谱系地理学和物种分布模型方法开展气候变化对动物的影响及其机制研究，已成为了解珍稀濒危动物受胁机制与保护对策的一个重要方向。我国珍稀特有雉科鸟类白冠长尾雉分布在秦岭—大巴山（神农架）—大别山区域，近期分布区缩小且片段化严重，因此探讨气候变化对白冠长尾雉遗传多样性和分布区的影响对于全面了解该物种受胁原因具有重要意义，但相关研究尚未开展。本研究拟综合利用多基因分子标记和多模型集成的物种分布模拟方法，探讨气候变化对白冠长尾雉遗传多样性和分布区的影响，阐明白冠长尾雉的濒危机制，以期更准确、更有针对性地对白冠长尾雉进行保护。同时，也为深入了解秦岭—大巴山（神农架）—大别山区域的物种进化历史和多样性维持机制提供案例。

Towards the end of the Quaternary, climate has been a major driver of population change in the North Hemisphere. Coupling phylogeography and species distribution models to examine the response of endangered animals to the Quaternary climate, has become an important developing direction of conservation. However, the response of genetic signatures and geographical distribution areas of the Syrmaticus reevesii, which distributed across the regions in the Qinling, Dabashan (Shennongjia) and Dabie Mountains and the surrounding areas, to climate change is still unknown. By coupling species distributed models and multi-locus molecular data, we aim to investigate how climate changes affected species dynamics at distribution and genetic scales of Syrmaticus reevesii. It woud be helpful to protect the species more accurately and effectively. In addition, we will provide case of the evolutionaly pattern and related mechanism of species across these studied areas.
