Figure 2From: Genetic flow directionality and geographical segregation in a Cymodocea nodosa genetic diversity networkGenetic 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.Back to article page
