The opposed forces of differentiation and admixture across glacial cycles in the butterfly Aglais urticae
Abstract Glacial cycles lead to periodic population interbreeding and isolation in warm‐adapted species, which impact genetic structure and evolution. However, the effects of these processes on highly mobile and more cold‐tolerant species are not well understood. This study aims to shed light on the...

Abstract Glacial cycles lead to periodic population interbreeding and isolation in warm‐adapted species, which impact genetic structure and evolution. However, the effects of these processes on highly mobile and more cold‐tolerant species are not well understood. This study aims to shed light on the phylogeographic history of Aglais urticae , a butterfly species with considerable dispersal ability, and a wide Palearctic distribution reaching the Arctic. Through the analysis of genomic data, four main genetic lineages are identified: European, Sierra Nevada, Sicily/Calabria/Peloponnese, and Eastern. The results indicate that the Sardo‐Corsican endemic taxon ichnusa is a distinct species. The split between the relict lineages in southern Europe and the main European lineage is estimated to have happened 400–450 thousand years ago, with admixture observed during the Quaternary glacial cycles, and still ongoing, albeit to a much smaller extent.
