Figure 3. A in Phylogenetic relationships and biogeographic range evolution in cat-eyed snakes, Boiga (Serpentes: Colubridae)

Figure 3. A, BioGeoBEARS geographic range evolution of Boiga under the highest supported model scheme (biogeographic model = DIVALIKE+J, dispersal direction = unconstrained and dispersal rates = faunal similarity). Pie charts at internal nodes indicate the posterior estimate of ancestral geographic distributions and rectangles at tips indicate modern geographic distributions. B, model scheme AIC score (red bar) and corresponding null distribution of AIC scores (grey bars) for each of the five model schemes with biogeographic model = DIVALIKE+J (dispersal rate multipliers either: all equal, random or proportional to faunal similarity; dispersal direction either: constrained or unconstrained). Null AIC distributions and P-values are from permutation tests of dispersal rate multipliers; P <0.05 indicates significantly better model fit under the alternative model scheme compared to permutation set of model schemes; see Supporting Information, Figures S1–5 for results under the other biogeographic models.
