032 Duplicitous Dendrobatids

Frogs come in loads of crazy colours - but the reasons why can be quite complicated. We try to get to grips with some fascinating new research which suggests frogs can be both cryptic and shockingly obvious. Of course we have an amphibian Species of the Bi-Week. FULL REFERENCE LIST AVAILABLE AT: herphighlights.podbean.com Main Paper References: Barnett, JB, C Michalis, NE Scott-Samuel, and IC Cuthill. 2018. “Distance-Dependent Defensive Coloration in the Poison Frog Dendrobates Tinctorius , Dendrobatidae.” Proceedings of the National Academy of Sciences, 201800826.
