Notes: Analyses were conducted using the ultrametric tree obtained in BEAST. All outgroups and intermittent taxa were pruned to obtain the ingroup clades A and B. Abbreviations: Pb – pure birth; Bd – birth-death; DDX – exponential density dependent; DDL – logistic density dependent; Yule2rate – Yule with 2 rates; Yule3rate – Yule with 3 rates; LH – log-likelihood; r1/r2/r3 – net diversification rates; a – extinction fraction; xp – rate change parameter DDX model; k – carrying capacity parameter DDL model; st1/st2 – timing of rate shift (mya); AIC – Akaike information criterion; ΔAICrc  =  difference between the best rate constant and rate variable models.
