Dans Annual Review of Ecology, Evolution, and Systematics (45 2014)

Hill numbers or the effective number of species are increasingly used to quantify species diversity of an assemblage. Hill numbers were recently extended to phylogenetic diversity, which incorporates species evolutionary history, as well as to f[...]
