Results of parameter estimation with fastsimcoal2 under three alternative models. Composite maximum likelihood estimates of: effective population sizes (N) are presented as the number of individuals per population; divergence times (T) are presented as the number of generations (i.e., number of years ago, as 1 generation = 1 year); and migration rates (m) are presented as 2Nm. See Figure 2 to determine where each parameter maps onto the respective model. 95% confidence intervals were calculated from 100 parametric bootstrap replicates
