| an empirical comparison of character-based and coalescent-based approaches to species delimitation in a young avian complex. | the process of discovering species is a fundamental responsibility of systematics. recently, there has been a growing interest in coalescent-based methods of species delimitation aimed at objectively identifying species early in the divergence process. however, few empirical studies have compared these new methods with character-based approaches for discovering species. in this study, we applied both a character-based and a coalescent-based approaches to delimit species in a closely related avia ... | 2013 | 24073650 |
