Evaluating phylogenetic tree shape: two modifications to Fusco and Cronk's method.
Measurement of the degree of asymmetry in phylogenetic trees is important because a tree's shape reflects the process by which it has grown. For example, highly asymmetric trees are evidence that species have had different potential for diversification. Of the tree shape measures in the literature, that proposed by Fusco and Cronk (J. theor. Biol.175, 235-243) appears to be particularly useful, because it does not require fully-resolved trees whose terminals are of equal taxonomic rank. The v...Expand abstract
