摘　　要：As the only mammalian group capable of powered flight,bats have many unique biological traits.Previous comparative genomic studies in bats have focused on long-term evolution.However,the microevolutionary processes driving recent evolution are largely under-explored.Using resequencing data from 50 black flying foxes(Pteropus alecto),one of the model species for bats,we find that black flying fox has much higher genetic diversity and lower levels of linkage disequilibrium than most of the mammalian species.Demographic inference reveals strong population fluctuations(>100 fold)coinciding with multiple historical events including the last glacial change and Toba super eruption,suggesting that the black flying fox is a very resilient species with strong recovery abilities.While long-term adaptation in the black flying fox is enriched in metabolic genes,recent adaptation in the black flying fox has a unique landscape where recently selected genes are not strongly enriched in any functional category.The demographic history and mode of adaptation suggest that black flying fox might be a well-adapted species with strong evolutionary resilience.Taken together,this study unravels a vibrant landscape of recent evolution for the black flying fox and sheds light on several unique evolutionary processes for bats comparing to other mammalian groups.
