Aim The strawberry poison frog, Oophaga pumilio, has undergone a remarkable radiation of colour morphs in the Bocas del Toro archipelago in Panama. This species shows extreme variation in colour and pattern between populations ...
Female preferences for aposematic signal components in a polymorphic poison frog

Maan, Martine E.; Cummings, Molly E.; Mappes, J. (2008)

Aposematic signals may be subject to conflicting selective pressures frompredators and conspecifics.We studied female preferences for different components of aposematic coloration in the polymorphic poison frog Oophaga ...

Sexual dimorphism and directional sexual selection on aposematic signals in a poison frog
