Fig. 4From: Multiple independent origins of auto-pollination in tropical orchids (Bulbophyllum) in light of the hypothesis of selfing as an evolutionary dead endFrequency distributions of diversification and transition rates. a Speciation rates, (b) extinction rates, (c) character transition rates, and (d) net diversification rates for outcrossing (subscript ‘O’) and selfing (‘S’) lineages estimated under the full (six-parameter) BiSSE model across 1,000 dated Beast trees using maximum likelihood procedures. The 95 % credible intervals of parameter values are shown along the x-axesBack to article page
