Terrestrial toadlets use chemosignals to recognize conspecifics, locate mates and strategically adjust calling behaviour
Among anuran amphibians evidence for chemical communication is scarce. We carried out three experiments to evaluate whether chemosignals influence the sexual behaviour of an Australian terrestrial toadlet, Pseudophryne bibronii. Substrate choice trials (experiment 1) revealed that females preferred to associate with substrate marked by either sex rather than an unmarked substrate and that males preferred substrate marked by females, but avoided substrate marked by other males.
