In this report, a conservation priority scenario for endemic birds of China's Mainland is proposed from a phylogenetic perspective. By utilizing and comparing seven phylogenetic diversity (PD) indices, the study shows that the top ifve endemic birds with high conservation priority are Ar-borophila ardens, A. gingica, A. ruifpectus, Lophophorus lhuysii and Alectoris magna respectively. The ranking of species, based on the IUCN Red List and PD indices, were compared by means of a Wilcox signed rank test and Pearson’s correlation, drawing the inference that the PD ranking of endemic birds for China's Mainland shows a distinct and statistically signiifcant difference from the IUCN rank-ing. Therefore, the ranking of conservation priority for endemic birds of China using PD indices might offer new insights on species conservation from an evolutionary-heritage perspective, serving as a complement to the IUCN ranking. 展开更多
