Figure 4 in Multilocus phylogeny, natural history traits and classification of natricine snakes (Serpentes: Natricinae)

Figure 4. Best shift configuration sampled by Bayesian analysis of macroevolutionary mixtures (BAMM) for the natricine phylogeny. Colours along the branches represent instantaneous rates of speciation, and the red circles represent shifts in the diversification regimes. These shifts are on branches leading to the North and Central American group (upper red circle) and one of the major Asian clades (lower red circle). For complete phylogeny, see Figure 2. For complete geographical distribution information, see Figure 6.
