This project will use ancient DNA from permafrost-preserved Steppe bison bones and bovid exome capture systems to build a detailed record of the genomic impacts of rapid climate and environmental change at the end of the Pleistocene (30 to 11 kyr). The project will analyse how ancestral genetic diversity is distributed amongst surviving bison populations, and the role of nuclear loci under selection and drift. It will create a novel temporal dataset of genomic adaptation and evolution, and will generate critical data for studies of evolutionary processes such as extinctions, speciation and conservation biology and management.

该项目将使用来自永久冻土保存的草原野牛骨骼和牛科动物外显子组捕获系统的古老DNA，建立更新世末（30至11 kyr）快速气候和环境变化对基因组影响的详细记录。该项目将分析祖先遗传多样性如何在幸存的野牛种群中分布，以及核基因座在选择和漂移中的作用。它将创建一个新的基因组适应和进化的时间数据集，并将为进化过程的研究，如进化，物种形成和保护生物学和管理产生关键数据。
