Conservation genomics of sibling grouse in boreal forests reveals introgression and adaptive population differentiation in genes controlling epigenetic variation

摘要

The Chinese Grouse(Tetrastes sewerzowi) and Hazel Grouse(T. bonasia) are sibling species that are well-adapted to harsh high-altitude and latitude habitats. In the current study, we sampled and sequenced 29 Chinese Grouse(n=16) and Hazel Grouse(n=13) from eight locations in China, Sweden,Germany, and northeast Poland to analyze population genetic diversity and structure, introgression, and local adaptation.
