| Abstract: | Geographic variation in the Black-throated Laughingthrush (Garrulax chinensis) is examined to infer the influence of Pleistocene glacial oscillations on the genetic diversity of its subspecies. Mitochondrial evidence suggests that the endemic Hainan Island taxon, G. c. monachus, is monophyletic, whereas its closest continental relatives, G. c. chinensis and G. c. lochmius, are not. Multilocus coalescent analysis based on two mitochondrial and two nuclear intron loci indicates inter-subspecific genetic differentiation during the Pleistocene and substantial post-divergence genetic introgression from G. c. chinensis into G. c. lochmius. In contrast, G. c. monachus experienced no post-divergence gene flow despite occasional land-bridge contact with its continental relatives, suggesting its isolation may have been imposed by ecology as well as geography. It is probably reproductively isolated and should be treated as a distinct species. |
