Interactions Between Airborne Sound and Substrate Vibration in Animal Communication

摘要: Airborne sound and substrate vibrations are communication channels inextricably linked through commonalities in signal production, propagation, reception. Bimodal recordings of acoustic calls reveal that components one modality often excite energy the other can thus be propagated to receivers via either channel. While studies airborne have proceeded largely independently another, frequency at which these modalities co-occur number sensitive both kinds underscore broad potential importance interactions between two channels. Nevertheless, only a handful species known use bimodal signals. This chapter summarizes what is about substrate-borne components, discusses how may shape evolution signals, identifies outstanding issues field along with promising avenues for future study.
