[Show abstract] [Hide abstract] ABSTRACT: Computing the phylogenetic diversity of a set of species is an important part of many ecological case studies. More specifically, let \(\mathcal {T}\) be a phylogenetic tree, and let R be a subset of its leaves representing the species under study. Specialists in ecology want to evaluate a function \(f(\mathcal {T},R)\) (a phylogenetic measure) that quantifies the evolutionary distance between the elements in R.
