In phylogenetic trees the addition and removal of taxa has large effects on tree topology, hence measures of branch support and tree stability should account for taxonomic composition. Currently no comprehensive system of composition-dependent parameters exists in any cladistic or phenetic strategy. We introduce several values and indices based on a modification of the original jackknife resampling. Their advantage is a complete evaluation and optimization of taxon composition in phylogenetic data. While related to the Jackknife Monophyly Index (JMI), our system of support measures expands beyond parsimony analyses, and includes indices estimating support for the entire phylogenetic tree based on individual branch supports.
