Table 5. Posterior parameter distribution (median and 95% confidence interval) for the most likely demographic scenario in each region (scenario 3 with an LGM bottleneck in Benin, West Cameroon and São Tomé and scenario 4 with a bottleneck during the penultimate glacial in South Cameroon and Gabon).

Abbreviation: LGM, last glacial maximum.

Current and bottleneck population sizes, N_e and N_BTN, and time of beginning t_a and end t_b of bottleneck are given, scaled by mutation rate μ.
