Does sociality imply a complex vocal communication system? A case study for Fukomys micklemi (Bathyergidae, Rodentia)

To integrate individuals into a social group, communication is necessary. In this study, we examined vocalizations of a social bathyergid, Fukomys micklemi , in order to investigate the relationship between sociality and communication.

Because of its social organization and subterranean lifestyle, we expected this species to have an extensive vocal repertoire. Fifteen different adult specific call-types and four juvenile specific call-types could be recognized, similar to those in other social species. A new call-category, linked to submissive behaviour, is described.
