Supplementary Text S1 Examples of literature discussing relationship between Feature Diversity and Phylogenetic Distance. "For any phylogenetic estimation, the relative branch length is assumed to predict the relative number of novel features that have arisen in a given line of descent." (Barker, 2002)p. 165. "Hence PD allows for the identification of assemblages of organisms that are likely to represent the broadest array of diversity. Because time is a measure of independent evolution, it is not focused on any particular suite of phenotypic characters but should be correlated with them all." (Soutullo et al., 2005) p. 249 "PD therefore identifies sets of taxa that maximize the accumulation of 'feature diversity'" (Forest et al., 2007) 757-760 "Maximising the preservation of PD will also tend to maximise the preservation of feature diversity, including unmeasured but ecologically important traits." (Cadotte & Jonathan Davies, 2010)p. 376. "Phylogenetic distinctiveness (PD) is a compound metric of all forms of genetypic, phenotypic ("feature" or "character" diversity) and functional diversity, both measurable and unmeasurable, so maximising PD thereby provides biological systems with the most options to respond to a changing world". (Collen et al., 2011)p. 2611. "We can say that any subset of species that has greater PD will be expected to have greater feature diversity." (Faith, 2013) p. 69-89. Other people wondering if it's a good thing to test: "It has long been assumed, and sometimes demonstrated, that within a habitat type the amount of ecological differentiation amongst species is proportional to the amount of evolutionary and genetic divergence." (Cadotte et al., 2008)p. 17012 "If species with high EDGE scores are generally odd, where we define odd as absolute distance from the average phenotype,…" (Redding et al., 2008) p. 606. Barker, G.M.
