The Information Content of Consensus Trees
Phylogenetic Information Content, a class of measures of the information provided by consensus trees based on the number of permitted resolutions of the consensus, is introduced. A formula for the number of permitted resolutions of Adams consensus trees is derived and a proof given. We argue that maximising PIC measures provides a sensible criterion for choosing among alternative consensus trees and we illustrate this for consensus trees of cladograms.
