Estimates of divergence times (τ) for three transisthmian Alpheus species pairs (A. wonkimi/ A. malleator (WM), A. estuariensis/ A. colombiensis (EC), A. panamensis/ A. formosus (PF)) across datasets, scaled by the substitution rate (µ). Error bars indicate 95% Bayesian credible intervals across all replicate runs. A Datasets that varied in species composition and the minimum number of individuals (m) or species (s) recovered at a locus, modeled with a constant mutation rate across loci and no migration. Parameter values for each dataset are listed in Additional file 1: Table 1. a and b triplet datasets include the focal species pair plus one outgroup species. B The Am4s2r dataset, modeled with either constant μ across loci and no migration (Regular), variable μ across loci (VarMut), or variable μ and migration allowed between A. panemensis/A. formosus (PFmigVarMut)
