Pleistocene divergence and long-term population decline in three endemic <em>Euphorbia</em> species of high conservation concern from the south-western Alps and the mountains of Corsica and Sardinia

In this study, we integrate genomic data (ddRADseq) with species distribution models to investigate the evolutionary and demographic history of three narrow-ranged endemic Euphorbia species (E. gayi, E. valliniana and E. variabilis) restricted to the south-western Alps, Corsica, and Sardinia. Using coalescent-based approaches, we infer divergence times and reconstruct long-term demographic trends, while also examining population structure and connectivity. This data archive contains genomic data derived from ddRADseq. For each analysis, the most relevant input and results files that should allow replication of the workflow are included. , , # Data from: Pleistocene divergence and long-term population decline in three endemic *Euphorbia* species of high conservation concern from the south-western Alps and the mountains of Corsica and Sardinia This data archive contains genomic data derived from ddRADseq.
