Historical gene flow and effective population sizes (Ne) in Isle Royale lake trout. Migration estimates (Ne*m) for historical gene flow greater than 2.5 are shown, as well as the value of theta (Θ = 4Ne*μ generations) for each water depth group (as calculated using MIGRATE 3.03 [72, 73]. The thickness of arrows corresponds to the relative strength of migration within each analysis
