Global view of genomic differentiation of plankton populations. A Distributions of the 113 taxa’s pairwise FST matrices. In red, pairwise FST of populations belonging to the same basin; in blue to different basins. B Pairwise FST matrix between basins. The values represent the mean of all the median-FST between stations regrouped according to the basin they belonged to. C Distributions of the taxa’s median pairwise FST, according to their size fractions. Black diamonds correspond to the mean of the distributions. The bars on the top correspond to the comparisons done by pairwise Wilcoxon tests (p-values: * < 0.05, ** < 0.01, *** < 0.001, **** < 0.0001) D Distributions of the taxa’s median pairwise FST, according to their taxonomic group. Black diamonds correspond to the mean of the distributions. Each bar corresponds to taxonomic groups displaying no significant differences. E Scatter plot, each dot is a taxon. The size of each dot reflects the global median FST of the taxa’s FST distribution (i.e., FST computed over all the populations of a taxon)
