Classes of evolutionary scenarios under comparison using ABC analyses. Pi, Pj, Pk and Pl represent the four sampled populations. Within each class different scenarios were obtained by permuting the four sampled populations at branch tips (Px) (see Table 4). Pu stands for an unsampled population. The ‘ancestral population’, with an effective population size of N, is represented in black. At time TO, it gave rise to diverging source populations in the endemic area with an effective population size of NO. (dark gray). At time TF., primary foundations occurred, that is, the source populations contaminated plantations (light gray) through a genetic bottleneck (of intensity NB., thin light-gray lines). Class II to Class VI scenarios involve secondary foundation events, where recently founded populations contaminated new localities, at time TS.; N. holds for the effective population sizes of sampled populations. ra stands for the admixture rate in the scenario Class III (see Table 1 for details).
