The model with the smallest AIC in the demographic modeling for Acheilognathus longipinnis and the estimated parameters with a 95% confidence interval. Tm: time point at which migration among the populations stopped; T1, time point at which the Nobi and Toyama populations differentiated; T2, time point at which the Osaka population and the ancestral population of the Nobi and Toyama populations differentiated; NN, Ne of the Nobi population; NT, Ne of the Toyama population; NO, Ne of the Osaka population; NAncNT, Ne of the ancestral population of the Nobi and Toyama populations; NAncONT, Ne of the ancestral population of the three local populations; MIG1–8, migration rate among the three local populations or the ancestral population of the Nobi and Toyama populations
