Webdata. This index is often referred to as the mean pairwise distance (MPD) between species (Webb et al. 2002), in which the average of the dissimilarities in trait values between all pairs of species is computed. This index is often referred to as the “unweighted MPD” because it gives the same weight to the dissimilarity between all pairs of ... WebAbbreviations: MPD, mean pairwise distance; MNTD, mean nearest taxon distance; SES, standardized effect size. The numbers of clustered (SES < 0) or overdispersed (SES > 0) assemblages are shown (based on MPD/MNTD), with the numbers in parentheses indicating significantly clustered/overdispersed assemblages. davis tartan bow tie
