Data from: Evolutionary history of Scinax treefrogs on land-bridge islands in south-eastern Brazil

Rayna C. Bell, Cinthia A. Brasileiro, Celio F. B. Haddad & Kelly R. Zamudio
AIM: We investigated how Pleistocene refugia and recent (~12,000 years ago) sea level incursions shaped genetic differentiation in mainland and island populations of the Scinax perpusillus treefrog group. LOCATION: Brazilian Atlantic Forest, São Paulo state, southeastern Brazil. METHODS: Using mitochondrial and microsatellite loci, we surveyed population structure and genetic diversity in Scinax from five mainland populations and three land-bridge islands to understand the roles of Pleistocene forest fragmentation and sea level incursions on genetic differentiation....

Data from: Molecular phylogeny of Aphyocharacinae (Characiformes, Characidae) with morphological diagnoses for the subfamily and recognized genera

Victor A. Tagliacollo, Rosana Souza-Lima, Ricardo C. Benine & Claudio Oliveira
The subfamily Aphyocharacinae was recently redefined to comprise eight genera: Aphyocharax, Prionobrama, Paragoniates, Phenagoniates, Leptagoniates, Xenagoniates, Rachoviscus and Inpaichthys. This new composition, however, is partly incongruent with results of published molecular studies especially with regards to the positions of Rachoviscus and Inpaichthys. Our goal was to investigate the monophyly of Aphyocharacinae and its interrelationships using three distinct phylogenetic methodologies: Maximum–likelihood and Bayesian analyses of molecular data, and also Parsimony analysis of a concatenated molecular and...

Data from: Humidity levels drive reproductive modes and phylogenetic diversity of amphibians in the Brazilian Atlantic Forest

Fernando Rodrigues Silva, Mário Almeida-Neto, Vitor Hugo Mendonça Do Prado, Célio Fernando Baptista Haddad & Denise De Cerqueira Rossa-Feres
AIM: The diversity of reproductive modes among amphibians provides a striking example of how differences in the biology of species furnish can provide important explanations for species distribution patterns on a broad scale. We hypothesized that sites with a higher humidity level will support more different modes of reproduction than drier sites and will consequently exhibit a higher phylogenetic diversity. Furthermore, we predict that if there is a gradient in the tolerance of reproductive modes...

Data from: Seed dispersal anachronisms: rethinking the fruits extinct megafauna ate

Mauro Galetti, , Pedro Jordano & Paulo R. Guimarães
BACKGROUND: Some neotropical, fleshy-fruited plants have fruits structurally similar to paleotropical fruits dispersed by megafauna (mammals >103 kg), yet these dispersers were extinct in South America 10–15 Kyr BP. Anachronic dispersal systems are best explained by interactions with extinct animals and show impaired dispersal resulting in altered seed dispersal dynamics. METHODOLOGY/PRINCIPAL FINDINGS: We introduce an operational definition of megafaunal fruits and perform a comparative analysis of 103 Neotropical fruit species fitting this dispersal mode. We...
