Mason, M.J. & Narins, P.M. (2010) Seismic sensitivity and communication in subterranean mammals. In: The Use of Vibrations in Communication: Properties, Mechanisms and Function across Taxa, pp.121-139. O'Connell-Rodwell, C.E. (ed). Kerala: Transworld Research Network.
In this chapter, we discuss the latest findings relating to seismic sensitivity in three groups of subterranean mammals, the spalacid mole-rats, the bathyergid mole-rats and the golden moles. As well as reviewing the literature, we develop some new hypotheses, among them the idea that the use of foot-drumming as a communication method might have evolved in a monophyletic clade containing the central/southern African bathyergid mole-rats (Batherygus, Georychus, Cryptomys and Fukomys), to the exclusion of Heterocephalus and Heliophobius. The chapter also includes the first published photomicrograph of the (very delicate!) middle ear apparatus of Eremitalpa .

I later examined the ear of spalacid mole-rats in more detail, expanding on some of the themes
The chapter subheadings are:
1. Introduction
2. Seismic communication and echolocation in spalacid mole-rats
2.1 Audition or somatosensation?
2.2 Somatosensory receptors in Spalax ehrenbergi
3. Seismic communication in bathyergid mole-rats
3.1 Potential mechanisms for seismic sensitivity in bathyergids
4. Seismic prey-detection in golden moles
4.1 The role of the middle ear in chrysochlorid seismic sensitivity
4.2 Ossicular hypertrophy in other species
5. Discussion
