Various scenarios for shifts in three Saxifraga clades under pure birth (PB) and birth-death (BD) processes were tested. Asterisks indicate scenarios in which selected clades were constrained to have the same net diversification rates. Log marginal likelihoods (LogL) and results from Bayes factor (BF) tests are given for analyses with minimum and maximum species
