Additional file 22 of Pattern and timing of diversification in the African freshwater fish genus Distichodus (Characiformes: Distichodontidae)

Additional file 22: Table S1. Probabilities of ancestral states/ranges at each node of the spatiotemporal reconstruction of Distichodus range evolution presented in Fig. 7. Columns indicate ancestral areas, represented by all unique combinations for all possible group sizes for the six ichthyofaunal provinces. Rows indicate nodes, with numbering following the typical R phylo format, i.e., 1 is the first tip taxon/area, beginning at the bottom. After the last tip value, the numbering begins at the root, and moves tipward. Ichthyofaunal provinces abbreviated as in Fig. 1.附加文件22：表S1。本表格收录了图7所示的双齿鱼属（Distichodus）分布演化时空重建各节点的祖先状态/分布范围概率。其中，列代表祖先分布区，由6个鱼类区系省（ichthyofaunal provinces）所有可能分组规模对应的全部唯一组合构成；行代表节点，编号遵循标准R语言phylo格式：编号1为首个末端分类单元/分布区，从系统发育树的底部开始计数。在最后一个末端编号之后，编号从根节点出发，并向末端方向依次递增。鱼类区系省的缩写方式与图1一致。
