Local biological diversity, also known as alpha diversity, has three different components: the number of species in a given area (taxonomic diversity), the number of distinct traits that these species have (functional diversity) and their evolutionary distinctiveness (phylogenetic diversity). The relationships among these components of diversity vary across geography reflecting the differences in eco-evolutionary processes among distant regions.

This study was motivated by the fact that different components of biological diversity have been shown to vary slightly in their geographical distribution: while species richness, phylogenetic diversity and functional diversity are broadly correlated, there are some regions where one measure of diversity is higher or lower than expected based on the others.
