Oryctulagus cuniculus sp. geographical distribution and ERV segregation profiles. Hierarchical clustering and heatmap (Dataset S4) illustrating presence or absence of ERV insertion junctions among O. cuniculus sp., sequenced as pooled DNA sampled from wild populations across the Iberian Peninsula, southern France, and the Porto Santo Island, as well as from domestic rabbits (13). The heatmap and cladogram show pairwise differences among individual groups: domestic (green), wild French (red), and wild Iberian (blue). The two subspecies O. c. cuniculus and O. c. algirus are indicated, as well as rabbit populations sampled from a hybrid zone on the Iberian Peninsula (12, 13).
