![]() Among the sources of anthropogenic impact, acoustic pollution is increasingly becoming a threat for natural communities worldwide 4. chemical, noise and light pollution 1, 2 is one of the major causes of the global biodiversity crisis 3. Our study demonstrates a clear negative effect of anthropogenic vibrations on anuran communication, and the urgent need for further investigation in this area.Įnvironmental pollution (e.g. Since females of several species prefer males with higher call rates, our results suggest that anthropogenically derived substrate-borne vibrations could reduce individual reproductive success. Our results showed a significant call rate reduction by males of Alytes obstetricans in response to both seismic sources, whereas other parameters remained stable. In their natural habitat, a buried tactile sound transducer was used to emit simulated traffic and wind turbine vibrations, and changes in the toads’ acoustic responses were analyzed by measuring parameters important for reproductive success: call rate, call duration and dominant frequency. ![]() Playback tests were used to assess the effects of substrate vibrations produced by two sources of anthropogenic activity– road traffic and wind turbines– on the calling activity of a naïve population of terrestrial toads. Amphibians comprise the terrestrial vertebrates most sensitive to vibrations, and since communication is crucial to their survival and reproduction, they are a suitable model for investigating this timely subject. Nevertheless, the role of anthropogenic substrate vibrations in disrupting animal behavior is poorly understood. ![]() Anthropogenic disturbance is a major cause of the biodiversity crisis. ![]()
