Is the response of a Neotropical poison frog (Ranitomeya variabilis) to larval chemical cues influenced by relatedness?
Offspring recognition via chemical cues is widely known among vertebrates. In order to test this capacity in the poison frog Ranitomeya variabilis, we analysed whether parental frogs deposit their tadpoles with closely related rather than unrelated tadpoles. We conducted poolchoice experiments with one pool presenting chemical cues of a tadpole previously found at the same location. Tadpoles were most frequently deposited in pools without tadpole cues and results of genetic analyses did not lead to the conclusion that frogs consider relatedness when choosing where to deposit tadpoles. We suppose that frogs discriminate possible tadpole deposition sites by location rather than by offspring recognition.

More about this publication?
- The Herpetological Journal is an international scientific journal that publishes papers on the natural history of amphibians and reptiles. Experimental, observational and theoretical studies are published along with reviews and book reviews. Faunistic lists, letters and results of general surveys are not published unless they shed light on herpetological problems of wider significance.
