The 'Paradox' of Poisonous Frog Resistance against Their Own Toxins Explained (7 of 16)

Caption

Recently described in 2008, the Nariño poison frog (Epipedobates narinensis) inhabits humid subtropical forests of southwestern Colombia. Like the little devil poison frog, it is threatened by habitat destruction. Photographed in the Reserva Natural Biotopo Selva Húmeda, Nariño Department, Colombia in September 2016. 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."
