Figure 5. Results from ancestral state reconstructions of biogeography against the total evidence phylogenetic tree.

(A) Continuous trait geocoordinates-based reconstruction—dotted loops around Pan- and crown Sirenia indicate 68% confidence ellipses of nodal reconstructions. (B) Discrete trait zone-based reconstruction—pie charts summarize marginal likelihoods of trait states at each node and numbers that follow tip names correspond to map IDs from Table S2.
