The 'Paradox' of Poisonous Frog Resistance against Their Own Toxins Explained

Caption

The little devil poison frog [Dendrobates (Oophaga) sylvaticus] is found in humid subtropical forests across southwestern Colombia and northwestern Ecuador. This species is heavily trafficked for the pet trade and its home range is rapidly degrading because of logging and development in the region. Photographed in Santo Domingo Province, Ecuador in September 2014. This material relates to a paper that appeared in the Sept. 22, 2017, issue of Science, published by AAAS. The paper, by R.D. Tarvin at University of Texas at Austin in Austin, Texas, and colleagues was titled, "Interacting amino acid replacements allow poison frogs to evolve epibatidine resistance."
