We analyzed the role of direct olfactory investigation in relation to seasonality, sex, and female rank via of a longitudinal study on 16 adult ring-tailed lemurs living in two groups at the Pistoia Zoo (Tuscany, Italy). The observations took place from May 1997 to March 1999 and lasted >1,500 h. Males were olfactorily more active than females except for skin licking, which also appeared to be associated with affiliative behaviors. Both sexes had peak frequency of direct olfactory monitoring during the reproductive season; contrarily, skin licking showed apparently random fluctuations. There is a significant positive correlation between rank and sniffing genitals performed by females on other females and a significant negative correlation between rank and sniffing genitals received: high-ranking females are mostly actors, while low-ranking females are mostly receivers. The continuous follow-up of the reproductive conditions of potential competitors suggests that sniffing genitals might play a role in female reproductive strategies.
