A simple translation from indices of species diversity to indices of phylogenetic diversity

Measures of phylogenetic diversity have two main objectives: first disentangling the processes that drive species assemblages and second defining priorities of conservation while considering how much each species might contribute to biodiversity. A now widely used approach for measuring phylogenetic diversity consists in summing branch lengths on phylogenetic trees. Thanks to this approach, a change of perspective has been done since the 90s in...
