Schematic representation of the level of gene flow between American (orange coloration; left hand side) and European eels (blue coloration; right hand side). Arrows depict directionality of the migration parameter m from either eel species scaled by the mutation rate (m = M/μ, with M being the migration rate per generation per gene copy, and µ being the mutation rate). Thickness of arrows indicates strength of gene flow, and are to scale with median values from Table 3.
