Darrel R. Frost,Taran Grant,Taran Grant,Julián Faivovich,Julián Faivovich,Raoul H. Bain,Alexander Haas,Célio F. B. Haddad,Rafael O. de Sá,Alan Channing,Mark Wilkinson,Stephen C. Donnellan,Christopher J. Raxworthy,Jonathan A. Campbell,Boris L. Blotto,Paul E. Moler,Robert C. Drewes,Ronald A. Nussbaum,John D. Lynch,David M. Green,Ward C. Wheeler +20 more
TL;DR: A new taxonomy of living amphibians is proposed to correct the deficiencies of the old one, based on the largest phylogenetic analysis of living Amphibia so far accomplished, and many subsidiary taxa are demonstrated to be nonmonophyletic.
Journal ArticleDOI
Systematics of the Neotropical Genus Leptodactylus Fitzinger, 1826 (Anura: Leptodactylidae): Phylogeny, the Relevance of Non-molecular Evidence, and Species Accounts
Rafael O. de Sá,Taran Grant,Arley Camargo,Arley Camargo,W. Ronald Heyer,María Laura Ponssa,Edward L. Stanley,Edward L. Stanley +7 more
TL;DR: The phylogeny of the species-rich clade of the Neotropical frog genus Leptodactylus sensu stricto is presented on the basis of a total evidence analysis of molecular and non-molecular evidence sampled from > 80% of the 75 currently recognized species.
Journal ArticleDOI
Xenopus Laevis as a Model Organism
TL;DR: In this article, comparative and evolutionary studies of Xenopus laevis and its relatives have been conducted and it has been shown that Xenopus is monophyletic and that Silurana is its sister group.

Molecular phylogeny of microhylid frogs (Anura: Microhylidae) with emphasis on relationships among New World genera
Rafael O. de Sá,Jeffrey W. Streicher,Relebohile Sekonyela,Mauricio C. Forlani,Simon P. Loader,Eli Greenbaum,Stephen Richards,Célio F. B. Haddad +7 more
TL;DR: Based on a divergence analysis calibrated with hypotheses from previous studies and fossil data, it appears that microhylid genera inhabiting the New World originated during a period of gradual cooling from the late Oligocene to mid Miocene.
