λ, speciation rates; μ, extinction rates; q, transition rates; d.f., degrees of freedom. The coding of photosynthetic pathways follows Coding Scheme 1 (S1): C₃ and C₃ – CAM intermediate are coded as “0”; strong CAM as “1.” Sorted from best-fit model from top to bottom (according to the lowest AIC value) with the best-fit and the full models highlighted in bold.
