Incorporation of phylogeny in biological diversity measurement: Drawbacks of extensively used indices, and advantages of quadratic entropy

Abstract

Using the indices δ+ and δ* for assessing phylogenetic diversity may lead to spurious results and interpretations; it can bias recommendations for conservation and lead to inappropriate management decisions. Therefore these indices should be avoided and other indices based on quadratic entropy (Qδ+ and Q) should be used instead. © 2011 WILEY Periodicals, Inc.
