Diversification analyses. Results of the MEDUSA analyses obtained using 1000 posterior trees randomly sampled from the BEAST posterior: A, angio-140, B, angio-200. Topologies are the maximum clade credibility tree of 1000 randomly selected trees (phylogenetic relationships between A and B are identical). Names of terminals refer to compartments defined in the Methods sections and detailed in Additional file 5. Branch colors illustrate the mean net diversification rate (r). Red dots denote significant shifts in r, their size being proportional to their frequency among the 1000 trees tested. Numbered shifts in Figure 2A: 1, crown node of the clade of Piperaceae and Saururaceae; 2, crown node of the clade of Piperaceae excluding Verhuellia; 3, crown node of Calycanthaceae; 4, crown node of the clade of Himantandraceae and Degeneriaceae; 5, crown node of the clade of Miliuseae and Monocarpia. The diagram in the top-right corner represents the frequency of the different model sizes (number of shifts) in the 1000-model collections for the two analyses (angio-140 and angio-200). Abbreviations: sp., species; Myr, million years.
