Individual body odour is known to provide information to conspecifics about both the identity
of the donor and its biological state (eg reproductive condition, age, diet). It is not clear
whether information related to individuality and biological state is evaluated collectively or
separately. To gain insight into this subject, we examined the effect of a change in diet on
conspecific recognition of individual chemical signatures in mound-building mice, Mus
spicilegus. The diet change consisted of the addition of an aromatic concentrate to the …
