Sexual dimorphism of the second-to-fourth digit length ratio (2D : 4D) in the Strawberry Poison Dart Frog (Oophaga pumilio) in Costa Rica
(2008)
The second-to-fourth digit ratio (2D : 4D) is a well-studied sexual dimorphism that likely arises as a result of prenatal androgenic effects on homeobox gene expression. This dimorphism has been found to exhibit interesting ...
Dietary specialization predicts toxicity in recently diverged lineages of poison frogs
(UniandesMaestría en Ciencias BiológicasFacultad de CienciasDepartamento de Biología, 2010)
Bright colourations allow dart-poison frogs to advertise bad taste and reduce predation. Several studies have proposed that skin alkaloids of poison frogs come from dietary sources, namely arthropods such as ants and mites. ...

Discrimination of offspring by indirect recognition in an egg-feeding dendrobatid frog, Oophaga pumilio
(2009)
Offspring discrimination, the differential treatment of offspring and unrelated young, functions in numerous animal taxa to ensure that vital and costly parental care behaviours are appropriately directed. Discrimination ...
