Figure 2

Character history and phylotype identification as inferred by PhyloType (MP reconstruction, ACCTRAN optimization). The topology used is from the ML analysis. Only significant phylotypes (whose sizes have a p- value ≤ 0.05) are indicated (filled circles at nodes with identifying numbers refer to phylotype identification in Table 1). A) Evolution of ancestral areas and phylotypes associated with this character, aphid species names are indicated as leaves of the tree. B) Evolution of host use and associated phylotypes, host species are indicated as leaves of the tree, N = not applicable. C) Evolution of feeding sites and associated phylotypes: aphid species names are indicated as leaves of the tree. Branches are coloured according to MP reconstruction (legends on the figure), and the root node identifiers of phylotypes are provided and refer to Table 1.
