Figure 7. WPGMA tree performed on axes 2 and 3 of the genetic landscape PCA. Only clusters supports ≤ 95% are reported above nodes. Approximately Unbiased (AU) are in red (left) and Bootstrap Probability (BP) are in green (right). Red squares represent clusters supported by an AU > 95%. Species labelled as in Supplementary Material 7. Mean genetic landscapes were computed for the main cluster groups (large, noted A to I) and for the clusters supported by AU > 95% as well as the sister nodes of main cluster groups (small). They were calculated as the mean of all genetic landscapes in their respective cluster (minus the multispecies landscape if present). The root corresponds to the multispecies landscape. Upper right: projection of the species labels from the genetic landscapes PCA axes 2 and 3, coloured according to WPGMA main cluster groups.
