摘要
The method of Estabrook, McMorris, and Meacham (1985, Syst. Zool. 34:193-200) to measure the similarity of two phylogenetic trees for the same collection of evolutionary units (EUs) has been generalized to include an evaluation of the similarity of the placement of individual EUs. These measures do not vary when the direction of evolutionary change along the individual branches is changed in either of the two trees being compared. Thus, these measures depend only on the convexity of various groups of EUs on the two trees. These measures are also applicable to phylogenetic trees that are only partially resolved. These concepts are illustrated with previously published pairs of estimates of the phylogenetic tree for genera of rodents and for genera of ducks.
