Data from: Hybridization promotes color polymorphism in the aposematic harlequin poison frog, Oophaga histrionica

Iliana Medina, Ian J. Wang, Camilo Salazar & Adolfo Amezquita
Whether hybridization can be a mechanism that drives phenotypic diversity is a widely debated topic in evolutionary biology. In poison frogs (Dendrobatidae), assortative mating has been invoked to explain how new color morphs persist despite the expected homogenizing effects of natural selection. Here, we tested the complementary hypothesis that new morphs arise through hybridization between different color morphs. Specifically, we (1) reconstructed the phylogenetic relationships among the studied populations of a dart-poison frog to provide...

Data from: Genome-wide evidence for speciation with gene flow in Heliconius butterflies

Simon H. Martin, Kanchon K. Dasmahapatra, Nicola J. Nadeau, Camilo Salazar, James R. Walters, Fraser Simpson, Mark Blaxter, Andrea Manica, James Mallet & Chris D. Jiggins
Most speciation events probably occur gradually, without complete and immediate reproductive isolation, but the full extent of gene flow between diverging species has rarely been characterized on a genome-wide scale. Documenting the extent and timing of admixture between diverging species can clarify the role of geographic isolation in speciation. Here we use new methodology to quantify admixture at different stages of divergence in Heliconius butterflies, based on whole genome sequences of 31 individuals. Comparisons between...
