Network topology of F. spiralis and F. vesiculosus individuals + simulated hybrids with the SAD. Only links with value smaller than or equal to the threshold values are present. Nodes representing individuals are circles for F. spiralis and squares for F. vesiculosus. Nodes representing hybrids are triangles. Colors correspond to geographical regions.
