Comparative genetic and demographic responses to climate change in three peatland butterflies in the Jura massif

Climate is a main driver of species distributions, but all species are not equally affected by climate change, and the differential responses of species to similar climatic constraints might dramatically affect the local species composition. In the context of climate warming, a better knowledge of the ability of dispersal-limited and habitat specialist species to track climate change at local scale is urgently needed. Comparing the population genetic and demographic impacts of past climate cycles in multiple co-distributed species with similar ecological requirements can help predicting their future response to climate warming, but such comparative studies remain rare. Here, we studied the relationship between population demographic history and past changes in spatial distribution of three protected peatbog butterfly species (Boloria aquilonaris, Coenonympha tullia, Lycaena helle) in the Jura massif (France), using a genomic approach (ddRAD sequencing) and species distribution modeling ..., , , # Data from: Comparative genetic and demographic responses to climate change in three peatland butterflies in the Jura massif Three VCF files containing SNP genotypes of sampled (1) *Boloria aquilonaris*, (2) *Coenonympha tullia* and, (3) *Lycaena helle* individuals in Franche-Comté, France. Snps genotypes were obtained through a ddRAD sequencing procedure and the STACKS de novo pipeline. ## Description of the data and file structure INFO columns of the VCF files are blank. Data were filtered as described in the article. ## Sharing/Access information In accordance with the French regulation regarding protected species (article L.124-4 of the environment code), sample names do not give any clue on their precise localization.
