  1. Shown are the number of model parameters (P) and coefficients for range expansion (dispersal, D), contraction (extinction, E), and founder events (jump, j). Coefficients based on our phylogeny should not be compared with other studies because of our relative time calibration. Extinction coefficients of approximately zero indicate estimates at parameter bound of the model. We ranked the models according to the difference of model-fit in comparison to the best model (ΔAICc). The two best models do not differ substantially in their support (ΔAICc < 2) and showed similar ancestral habitat estimates
