Habitat structure drives the evolution of animal vocal signals

Evidence

The acoustic adaptation hypothesis (AAH) states that the environment is an important cause of modification and alteration of acoustic signals. Dominant frequencies and other long-distance calls are the result of interaction between the animals and their environment to maximize the efficiency of the emitted sounds. Frequency and structure of acoustic repertoire are plastic traits that can be modified according to environmental constraints. — Almo Farina, Soundscape Ecology, 494
