Tree files for the Bayesian analysis (NEXUS format). All Bayesian analysis were conducted in BEAST v. 1.8. This is described in section 2.4 of the paper (2.4 Phylogenetic reconstruction). The files were generated using the software associated with BEAST: LogCombiner and TreeAnnotator as described in section 2.4. The LogCombiner files contain all trees generated from 3 independent runs with burn-in removed for each analysis (i.e. 27,000 trees); here called ‘LogC’ files. The TreeAnnotator files contain a single consensus topology generated from these 27,000 trees (a maximum clade credibility tree, keeping target node heights); here called ‘TAn’ files. ‘P’ in the file name simply stands for ‘partitioned’; however all phylogenetic analyses with more than one locus were partitioned whether this is stated in the file name or not.
