Abstract: Males of the Malaysian bushcricket species Mecopoda elongata synchronize or alternate their cyclically occurring song elements (chirps) in a duet. The acoustic interaction of males interacting in a duet was successfully simulated by means of mutually coupled song oscillators, which respond to a disturbance by a phase shift which is known from the phase response curves (PRCs) of real males. However, little is known about the acoustic interaction of males in a complex chorus situation. Therefore, the aim of the current study was to extend the duet model to a chorus taking into account an inhomogeneous spacing of agents and a natural variability of oscillator properties. This chorus model was used to study oscillator coupling in a chorus consisting of 15 agents. Since such a computer model allows one to simulate chorus manipulations that far exceed the possibilities of behaviour experiments, the following scenarios were simulated: modification of chorus density, sensory bias during sound production, selective attention to only a subset of neighbors and males joining or leaving a chorus. Simulation results allow one to draw conclusions about the chorusing behavior of males in a real chorus and about signaler and receiver aspects influencing chorusing formation and mate choice.
