  1. Models of transitions in sexual system across the best scoring ML estimation of Notostraca phylogeny compared using the ML implementation of BayesMultistate. lnL = log-likelihood of model, q GA  = transition rate from gonochorism to androdioecy, q AG  = transition rate from androdioecy to gonochorism, p = p-value for D with 1 degree of freedom comparing the restricted models to the unrestricted model.
