Article: New insights to the molecular phylogenetics and generic assessment in the Rhacophoridae (Amphibia: Anura) based on five nuclear and three mitochondrial genes, with comments on the evolution of reproduction.[show abstract] [hide abstract]
ABSTRACT: The phylogenetic relationships among 12 genera of treefrogs (Family, Rhacophoridae), were investigated based on a large sequence data set, including five nuclear (brain-derived neurotrophic factor, proopiomelanocortin, recombination activating gene 1, tyrosinase, rhodopsin) and three mitochondrial (partial 12S and 16S ribosomal RNA and the complete valine t-RNA) genes. Phylogenetic analysis of the nuclear gene sequences resolved three major clades. The first group included Philautus, Pseudophilautus, Kurixalus, Gracixalus, and Theloderma moloch; Pseudophilautus and Kurixalus were sister taxa. The second group consisted of Nyctixalus and Theloderma. The third group contained Feihyla, Polypedates, Rhacophorus, and Chiromantis vittatus; Polypedates and Feihyla were sister taxa. Analyses of the nuclear and mitochondrial genes supported the following results: (1) Genus Liuixalus formed the sister group of all other rhacophorines. (2) Philautus, Theloderma, and Chiromantis were not resolved as monophyletic genera. Four groups, including Philautus ocellatus and P. hainanus, P. longchuanensis and P. gryllus, P. banaensis, and P. quyeti nested well within the genera Liuixalus, Pseudophilautus, Kurixalus, and Gracixalus, respectively. (3) Theloderma moloch and Chiromantis vittatus did not cluster with other species of Theloderma and Chiromantis, respectively. Foam nesting evolved only once, as did laying eggs in a jelly-like matrix containing some bubbles. Terrestrial direct development evolved twice in the Rhacophoridae.Molecular Phylogenetics and Evolution 08/2009; 53(2):509-22. · 3.61 Impact Factor

ABSTRACT: Phylogenetic relationships among representative species of the subfamily Raninae were investigated using approximately 2000 base pairs of DNA sequences from two mitochondrial (12S rRNA, 16S rRNA) and two nuclear (tyrosinase, rhodopsin) genes. Phylogenetic trees were reconstructed using maximum parsimony, Bayesian, and maximum likelihood analyses. Comparison between the nuclear and mitochondrial findings suggested that our final combined data has higher resolving power than the separate data sets. The tribes Stauroini and Ranini formed a sistergroup relationship, and within Ranini, ten major clades were consistently resolved among all analyses based on the final combined data, although the phylogenetic relationships among the ten clades were not well resolved. Our result refuted several previous taxonomic divisions: the genus Pseudoamolops was invalid, and the monophyly of the genera Amolops and Rana were not supported. We suggest elevating Raninae to familial status, and recognizing within the family, at least twelve genera including Staurois, Meristogenys, Clinotarsus, Amolops, Hylarana, Babina, Odorrana, Pseudorana, Rana, Lithobates, Glandirana, and Pelophylax. A broader sampling of species and data from more molecular markers are needed to confidently resolve the phylogenetic relationships among Ranidae.Molecular Phylogenetics and Evolution 05/2007; 43(1):1-13. · 3.61 Impact Factor
Article: Molecular phylogeny of the Chinese ranids inferred from nuclear and mitochondrial DNA sequences[show abstract] [hide abstract]
ABSTRACT: The phylogeny of representative species of Chinese ranids was reconstructed using two nuclear (tyrosinase and rhodopsin) and two mitochondrial (12S rRNA, 16S rRNA) DNA fragments. Maximum parsimony, Bayesian, and maximum likelihood analyses were employed. In comparison with the results from nuclear and mitochondrial data, we used nuclear gene data as our preferred phylogenetic hypothesis. We proposed two families (Ranidae, Dicroglossidae) for Chinese ranids, with the exception of genus Ingerana. Within Dicroglossidae, four tribes were supported including Dicroglossini, Paini, Limnonectini, and Occidozygini. A broader sampling strategy and evidence from additional molecular markers are required to decisively evaluate the evolutionary history of Chinese ranids.Biochemical Systematics and Ecology.
