Figure 1From: Travelling in time with networks: Revealing present day hybridization versus ancestral polymorphism between two species of brown algae, Fucus vesiculosus and F. spiralisNetwork topology of F. spiralis and F. vesiculosus individuals with the Rozenfeld Distance (RD). Only links with value smaller than or equal to the percolation distance Dp = 7.15 are present. Nodes representing individuals are circles for F. spiralis and squares for F. vesiculosus. Colors correspond to geographical regions. One can identify 2 clusters, one for F. spiralis individuals and the other for F. vesiculosus.Back to article page
