Fig. 6 in Disporella guada sp. nov., an erect-ramose rectangulate cyclostome (Bryozoa, Stenolaemata) from the Caribbean Sea: convergent evolution in bryozoan colony morphology
Fig. 6. Bayesian analysis of the concatenated 18S + 28S rDNA dataset constructed using MrBayes ver. 3.6.2 under the GTR + I + G model of nucleotide evolution. The analysis was run for 10 million generations; 7 million generations were discarded as burn-in. Posterior probabilities are given at the nodes. All nodes with <0.95 posterior probabilities have been collapsed. The branch length scale bar indicates number of substitutions per site. Higher level classification is given at the right-hand side. Emboldened terminals indicate newly generated data.
