BAMM outputs. Phylorate plots (2a) and speciation rate through time curve for Convolvuleae (2b). Additional file 2a represents the distinct shift configurations that account for 95% of the probability of the data (f-values denote the posterior probability of each shift configuration). Branches are scale colour-coded to indicate rate variation from red (acceleration) to blue (deceleration). Circles indicate the location of core rate shifts and are similarly colour-coded, with circle size proportional to the marginal probability of a shift. Additional file 2b represents a speciation rate through time curve (red) for Convolvuleae. Blue shading represents the confidence on speciation rate at any point in time. (ZIP 474 kb
