Pooled whole genome sequence data for Lycaeides butterflies
We used pooled whole-genome sequence data from more than 20 populations representing three nominal species and multiple admixed or taxonomically ambiguous populations, we show that widespread admixture in Lycaeides butterflies has resulted in distinct evolutionary histories within and among chromosomes, with the most notable differences between the autosomes and the Z sex chromosome. This is part of a larger project analyzing evolution in this butterfly group across space and over time.
