For lemurs, genetic diversity and scent complexity go hand in hand during the breeding season, say researchers from Duke University and the Centre d'écologie fonctionnelle et évolutive (CNRS / Universités Montpellier 1, 2 and 3 / ENSA Montpellier / CIRAD / École pratique des hautes études de Paris).
Male lemurs are able to signal their genetic quality through an olfactory cue. The perfume attracts females and provides the basis for their choice of reproductive partner.
Olfaction, little studied in primates until now (1), is a significant means of communication in certain monkeys, and especially in lemurs. These mammals, which live almost exclusively in Madagascar, include more than thirty species. One of the best known is the ring-tailed lemur, Lemur catta, a highly social species that lives in small, female-dominated groups. In this species, olfactory communication plays an essential role in social relations.
