Likelihood scores, harmonic means and Bayes factors approximated under Tracer for each partitioning strategy of the MrBayes 3.1.2 analyses for the gene trees.

<p>The Bayes factors are given for each possible comparison of strategies in the three last columns of the table. The analyses with the partitioning strategies ‘12v3’ are the best analyses for both genes (COI and EF1-α). The analysis with the partitioning strategy ‘BySix’ is the best analysis for the combined dataset, and is chosen for the dating analyses as a tree prior.
