Abstract:Vocalizations play a major role in communication of mammals with subterranean lifestyles since other senses are dramatically restricted in the environment of below ground burrows. In our study, we recorded vocalizations of 10 adult males and 10 adult females of a social bathyergid, the Mashona mole-rat (Fukomys darlingi) in different behavioural contexts. Vocalizations were divided into four categories according to behavioural contexts. Similar to other subterranean mammals, the range of Mashona mole-rat calls is shifted towards lower frequencies. We described 10 types of true vocal signals and 2 mechanical sounds. The vocal repertoire of the Mashona mole-rat is less rich compared to other social mole-rats, corresponding with its low mean family size. Interestingly, this species has a higher diversity in contact and distress calls, while using a relatively low number of aggressive signals.
