Human-driven habitat fragmentation and loss influence population properties (population size, density, immigration patterns, recruitment, etc.) that have a direct effect on the strength of social interactions. The latter, in turn, condition animal communication, which regulates information exchanges between homo and heterospecifics. This paper reviews studies that have shown an impact of habitat fragmentation on communication systems, either on innate signals (such as communication in amphibians) or socially learned (birdsong). This type ofanthropogenic disturbance can determine a shift in communication systems in different habitat types (forest, scrub and steppeland, agricultural and urban habitats), with examples in every continent. In some cases, animals responded adaptatively to the new conditions imposed by humans, while in other cases, negative effects on individuals and populations are predicted, generating potential conservation problems.
