Table 5 Marginal populations’ demographic history estimation statistics (mean, median, mode) of the posterior distribution for the parameters ancestral effective population size (Nanc), and the effective population size (Ne) after a bottleneck event at time 1 (t1), including their 95% CI under the best model (Scenario 1). Values interpreted and discussed in the paper are those of the mode (bold)

  1. aAbsolute time (in years before present) was calculated by multiplying the mode of t1 with the generation time of the species set at 8 years [35] and/or 6–10 years (in parenthesis) according to [34]. Upper and lower CIs were multiplied by 8 years
