Figure 2. Cross validation of all fossil and phylogeographic constraints.

Figure 2

The dashed black line indicates the prior, as specified in all BEAST runs including this constraint. The solid black line shows the marginal densities of BPPs for each node when its constraint is relaxed and its date estimated based on all other constraints. At this stage, only five out of ten (B, G, H, I, J) nodes showed a good fit between prior and posterior. A new BEAST analysis (‘-ACDEF’) was conducted, using only constraints B, G, H, I, and J. Results of this analysis (solid grey line) showed a good fit between prior and posterior for node C, therefore node C was reincluded in a final BEAST run (‘-ADEF’; dashed grey line).
