Interspecific and intraspecific views of color signals in the strawberry poison frog Dendrobates pumilio
The results indicate that the colors displayed by the various color morphs of D. pumilio are effective signals both to conspecifics and to a model predator. Expand
Amazonian Amphibian Diversity Is Primarily Derived from Late Miocene Andean Lineages
This work reconstructed the biogeography of the poison frog clade (Dendrobatidae) using a novel method of ancestral area reconstruction and relaxed Bayesian clock analyses, and rejected an Amazonian center-of-origin in favor of a complex connectivity model expanding over the Neotropics. Expand
Visual mate choice in poison frogs
Results indicate that female D. pumilio use visual cues in mate choice, and suggest that colour may be the visual cue they use. Expand
Variation in Spectral Reflectance Among Populations of Dendrobates Pumilio, the Strawberry Poison Frog, in the Bocas Del Toro Archipelago, Panamá
It is argued that variation in coloration may have been enhanced by sexual selection, and there is some evidence for clinal variation in colour and pattern across some mainland populations. Expand
A taxonomic revision of the Neotropical poison frog genus Ranitomeya (Amphibia: Dendrobatidae)
The Neotropical poison frog genus Ranitomeya is revised, resulting in one new genus, one new species, five synonymies and one species classified as nomen dubium. We present an expanded molecularExpand
A Key Ecological Trait Drove the Evolution of Biparental Care and Monogamy in an Amphibian
Evidence is provided from comparative analyses that an ecological factor (breeding pool size) is associated with the evolution of parental care across all frogs and that biparental care is essential to tadpole survival in small (but not large) pools. Expand

Comparative analysis of the evolutionary relationships among representative species of poison frogs indicated a significant correlation between the evolution of toxicity and coloration across this family, consistent with the hypothesis that coloration in this group is aposematic. Expand
Genetic structure is correlated with phenotypic divergence rather than geographic isolation in the highly polymorphic strawberry poison‐dart frog
The results show that phenotypic differences can result in sexual and natural selection against non‐native phenotypes, and these forces lead to genetic isolation between different colour morphs in the wild, presenting a potential case of incipient speciation through selection. Expand
Molecular phylogenetic evidence for a mimetic radiation in Peruvian poison frogs supports a Müllerian mimicry hypothesis
This work presents molecular phylogenetic evidence that the poison frog Dendrobates imitator mimics three different poison frogs in different geographical regions in Peru, providing the first evidence for a Müllerian mimetic radiation in amphibians. Expand
