Diversity type Diversity index Description
TD Species Richness Number of species per community
FD FDiv (Functional Divergence) Degree of functional dissimilarity within the community weighted by abundance (Villéger et al. 2008).
FEve (Functional Evenness) Regularity of distribution of species abundances in functional space as a measure of resource utilization (Villéger et al., 2008).
PD MPD (Mean Pairwise Distance) Average nodal distance on a phylogenetic tree between species of a community (Webb, 2000). High values indicate species in the community are distributed across a wide range of clades, while low values mean the species in the community are clustered.
sesMPD (standard effect size Mean Pairwise Distance) MPD adjusted for species richness. Positive sesMPD values indicate communities with higher MPD than expected (overdispersed), and the opposite for negative values (clustered).
