- Arrows specify the direction of introgression. Ln(mL) are the log marginal-likelihoods estimated using the Bezier approximation. Log Bayes factors (LBF) are calculated by comparing Model x with the Model x − 1
- Sp—S. perrico, Sr—S. rubroviolaceus, Sg—S. ghobban
- a Models 3, 4, and 6 include a constant low migration parameter (M = 0.001) to meet the assumptions of connectivity among all populations. Italic text indicates the best fitting model = Model 6
