Using Phylogenetic Diversity Measures to Set Priorities in Conservation: an Example from Southern

摘要: Phylogenetic diversity measures rank areas for biodiversity conservation priorities based on infor- mation encoded in phylogenies (cladograms). The goal of these ranks is to consider as many factors possible that provide additional taxic information, such taxa richness, distributional pat- terns, area endemicity, and complementarity between areas. At present there are con- sider phylogenetic including node-based, genetic-distance, feature-based measures. We de- vised a modified node-based index we call "taxonomic endemicity standardized weight," which considers not only the taxonomic distinctness inhabit given but their endemic- ity well. Once weight identifies highest priority, can be used identify second so on. this priority southern South America, compared results our rankings other indexes. Our identified Santiago district, Central Chile province, conservation, followed by Maule, Malvinas, districts Subantarctic prov- ince. Malvinas exhibits greater relative than Maule does, however, ranked priority.
