Estimates of effective population size (Ne) and dispersal rate (m) from temporal samples of two populations from the Volta basin using three different methods: (1) maximum likelihood temporal method to jointly estimate Ne_open and migration m [36], (2) pseudo-likelihood temporal method to estimate Ne_closed [38], and (3) point-estimate Linkage-Disequilibrium based method LD-Ne [37] averaged over the different temporal samples (KpM2 (n = 13) was excluded from the calculations).
