Olfactory discrimination learning in small nocturnal primates (Microcebus murinus and M. lehilahytsara)



Olfactory communication is of high significance especially for nocturnal animals. The arboreal mouse lemurs, which are endemic to Madagascar, are predestinated for this kind of communication due to their dispersed lifestyle. Marking behaviour was described in different situations: sleeping sites are marked when the animals leave at the beginning of the night to ensure this resource, females show marking behaviour much more frequently during oestrus to advertise their reproductive state to possible mates and intraspecific dominance is probably communicated by urine marks. The urine of male M. lehilahytsara and M. murinus was recently tested for its protein content in cooperation with the working group of Prof. Rob Beynon from the University of Liverpool.  This collaboration revealed a so far unknown Protein (WFDC12), which is excreted from males of both species, but not from all males and only in the breeding season. The function of this protein is still unknown. It is, however, largely unknown, what kind of urinary signatures of mouse lemurs are indeed detected and discriminated by other mouse lemurs. Therefore the aim of my project is to investigate the olfactory learning capabilities of mouse lemurs and to test whether they are able to discriminate between urine samples containing different signatures.
