Rising above the noise: the influence of population dynamics on the evolution of acoustic signaling

Journal of Physics: Complexity
Acoustic signaling is employed by many sexually reproducing species to select for mates and enhance fitness. However, signaling in dense populations can create an auditory background, or chorus, which may interfere with a signal receiver’s phonotactic ...
