By Roseli Pellens, Philippe Grandcolas

This booklet is set phylogenetic variety as an method of decrease biodiversity losses during this interval of mass extinction. Chapters within the first part take care of questions corresponding to the best way we worth phylogenetic variety between different standards for biodiversity conservation; the alternative of measures; the lack of phylogenetic variety with extinction; the significance of organisms which are deeply branched within the tree of lifestyles, and the position of relict species. the second one part consists by means of contributions exploring methodological facets, reminiscent of tips to care for abundance, sampling attempt, or conflicting timber in research of phylogenetic range. The final part is dedicated to functions, exhibiting how phylogenetic range could be built-in in systematic conservation making plans, in aspect and HEDGE reviews. This broad assurance makes the publication a reference for teachers, coverage makers and stakeholders facing biodiversity conservation.

2012) argue that phylogeny largely determines interactions among species, and so could help predict the cascade of extinctions through ecological networks and hence the way in which those extinctions impact ecosystem function. So, on this account, phylogenetic diversity is at least a surrogate for ecosystem function. Forest et al. (2007) find a stronger correlation between phylogenetic diversity and feature diversity than between species diversity and feature diversity. So they recommend that we employ phylogenetic diversity, rather than species diversity, as a surrogate for feature diversity.

That said, we noted in section “A maze of measures” that there are many measures of phylogenetic diversity. If conserving phylogeny is justified as a means of hedging our bets against uncertainty, this may help us to wrangle the current diversity in measures of phylogenetic diversity discussed earlier. Variety in topological measures of phylogenetic diversity reflects the fact that phylogeny is complex. Species do not always bifurcate cleanly. Lineages reticulate and so on (Dagan and Martin 2006).
