Calculated values for the four scenarios provided in Figure 1 using the six presence-absence weighted metrics used in the article.

Further the original phylogeny (λ = 1) was lambda transformed [24] four times to produce phylogenies that were increasingly ‘tippy’ ending with a ‘star’ phylogeny where all species are equally related. This simplified example highlights the similarity or redundancy of some of the phylogenetic beta diversity metrics utilized. It also shows that the metrics converge as the phylogeny becomes more ‘star-like’ at which point very little phylogenetic information is available.
