Values with the highest posterior probabilities for the parameters investigated for the popABC analysis, with comparisons between regions one, two and four (R1, R2 and R4).

Parameters investigated are average mutation of the sequence (AvMutS), migration into each population (mig1 and mig2), effective population size of the ancestral population (NeA1) and time of population splitting (t1). Effective population size of each population (Ne1 and Ne2) were omitted from the table due to lack of convergence.
