Barker, G.M. 2002. Phylogenetic diversity: a quantitative framework for measurement of priority and achievement in biodiversity conservation. Biological Journal of the Linnean Society 76: 165–194.
Biodiversity option value can be equated with richness of features expressed by species. Feature diversity of communities can be predicted by the phylogenetic relationships among species. The ‘Phylogenetic Diversity’ measure (PD) estimates the relative feature diversity of any nominated set of species by the patristic or path-length distances. This study reviews and expands on some of the properties of PD, and develops simple modifications of the measure to enable capture of both the phylogenetic relatedness of species and their abundances. The application of PD concepts to a range of conservation and resource management issues is demonstrated using New Zealand avian case studies.
