Phylogenetic Diversity and the Sustainable Use of Biodiversity

摘要: Sustainable use of biodiversity requires the in a way that does not foreclose benefits for future generations. Biodiversity option values reflect this capacity to provide are often unanticipated. The phylogenetic diversity measure, PD, quantifies represented by different sets species. PD can be interpreted as counting-up features This allows species-level ecological indices converted indices, including complementarity and endemism, integrated into systematic conservation planning. PD’s power law relationship with species counts supports findings initial losses may retain high PD. suggests occasional loss current-use might reduce overall However, if currently useful society concentrated particular clades on phylogeny, then their imply high-PD loss. Conservation maintain values. planning results suggest phylogenetically clumped species, within given budget, produce tipping point which collapses.
