Comparison of nodal support between MrBayes and maximum likelihood methodologies. Shown is a scatter plot comparing the differences in MrBayes posterior probabilities (Pp) and maximum likelihood (ML) bootstrap support (BS) for identical nodes (Figure 3). Open circles represent Pp support for discordant nodes present in MrBayes and absent in ML. Open triangles represent BS values for discordant nodes present in ML and absent in MrBayes. Note that MrBayes exhibits heightened overall node support as compared to ML.
