When more than one equally parsimonious tree is found during the constrained search for trees lacking the node of interest, averaging PBS for each data set across these trees can conceal conflict, and PBS should ideally be examined for each constrained tree. Similarly, when multiple most parsimonious trees (MPTs) are generated during analysis of the combined data, PBS is usually calculated on the consensus tree. However, extra information can be obtained if PBS is calculated on each of the MPTs or even suboptimal trees.enIncongruencePartitioned Bremer supportSimultaneous analysisJournal article002002069010.1111/j.1096-0031.2002.tb00159.x0001780318000042-s2.0-003670547560228
