Level of connectivity. Arrows indicate the demographic signal recovered with the ABC-skyline plot for each population based on model CHG1 (Fig. S1). The mode of the estimated Nm under the most supported metapopulation model (either model FIM or SST) is reported in parentheses. Up-arrow: demographic expansion; down-arrow: demographic reduction; right-arrow: constant population size. Population acronyms are reported in Table S1
