Genetic flow network for Cymodocea nodosa at growing values of the distance threshold. Clusters that appear when linking populations with a JSD distance smaller than a distance threshold T, for increasing values of T approaching from below the percolation threshold. (a) $T=0.57$. (b) $T=0.89$. (c) $T=0.95$. (d) $T=0.97$, just below the percolation threshold. The cluster colors are the same as in Figure 1.
