    The subterranean environment has strongly influenced the evolution of the sensory biology of subterranean rodents. While dark and monotonous tunnels have led to reductions in the visual capabilities of some species, other senses appear to be highly developed in contrast. Among them, the emission of acoustic and seismic signals plays a major role in communication and alertness of subterranean mammals. In this chapter, the ecological and evolutionary conditions that influence the characteristics of vibrational communication in subterranean rodents are reviewed. First, the characteristics of rodents’ burrows and how they dictate the methods used to study subterranean communication are discussed. Second, the properties and roles of vocalizations and seismic signals in subterranean species are examined, including the main hypotheses about the evolution of these signals. Third, what is understood about social and vocal complexity in subterranean rodents is summarized and the similarities and differences in the vocal repertoires of social and solitary groups are analyzed. The chapter ends with a short summary and a consideration of future challenges in the field of subterranean acoustic communication in rodents.Fil: Schleich, Cristian.
