Constraints on percussive seismic signals in a noisy environment by European fiddler crabs, Afruca tangeri.

ABSTRACT: Many animals communicate using seismic vibrations. Signaller morphology, signal production method and environmental factors impose interacting constraints that may be impossible to replicate in the laboratory, making it essential to study seismic communication in situ. Here, we focused on the constraints on percussive seismic signals in European fiddler crabs (Afruca tangeri), recording a large dataset of percussive seismic signals in situ, and testing for waveform differences as a function of signaller morphology and behaviour. In addition, we aimed to characterise signal degradation and interference by seismic noise from wind and vibrated vegetation in the natural environment. We obtained over 8000 percussive seismic signal recordings, and found that although the length, rhythm and loudn
