摘　　要：In this brief report,time-varying(including both gradual and abrupt change)and time-constant diversification models are fitted on a phylogeny of endemic birds of China's Mainland to test the diversification patterns of endemic birds in the region.The results show that phylogeny of endemic birds is best quantified by a constant-rate diversification model through model comparison.Limitations of the study are discussed.In particular,ignorance of non-endemic taxa and the limited sampling of endemic taxa could influence the conclusions of the study.
