Table 1. Posterior probabilities of the SC scenario and timing of secondary contacts.
Mean (bold) relative posterior probability of the secondary contact scenario and standard deviation (round brackets). Median (bold) and 95% confidence intervals (square brackets) for both the inferred ratio between divergence time (TSPLIT) and time of the secondary contact (TSC) and the secondary contact ‘expressed in number of years) after setting TSPLIT to 10 million years (the upper bound for the divergence of this species complex, Hipp et al. 2018). More details are given in Tables S2 & S3.
