From: Genetic structuring and migration patterns of Atlantic bigeye tuna, Thunnus obesus(Lowe, 1839)
Estimates of gene flow for bigeye tuna populations among ocean basins based on Bayesian inferences of migration rates and population sizes. Dots are the maximum posterior values, and the lines show the 95% credibility intervals. (A) Mutation scaled immigration rate, M, between ocean basins. M is the ratio of immigration rate and mutation rate. (B) Number of immigrants per generation, Nm. 95% confidence intervals are shown.
