Maternal Care in Free-Ranging Arboreal Grey-Cheeked Mangabeys (Lophocebus albigena johnstoni) in Kibale National Park, Uganda.

Abstract : Maternal styles have been intensively studied in a variety of terrestrial species of primates, but far less in arboreal species. However, to have a balanced view of the evolution of maternal care, it is necessary to investigate this behaviour in the context of habitat. Here, we investigate whether the mother’s parity, age and dominance rank, as well as the infant’s age and sex, influence maternal care and mother-infant proximity in arboreal grey-cheeked mangabeys (Lophocebus albigena). We observed 13 mother-infant dyads in four free-ranging groups for 6 months. Our main finding is that maternal care is a dynamic process affected by a mix of mothers’ and infants’ characteristics. We found that first-time mothers spent more time watching their infants than multiparous mothers, who carried, groomed and protected their infants more often. We also found that low-ranking mothers prevented their infants from leaving them more often than did high-ranking mothers. Moreover, mothers adjusted their care as infants became older. They groomed and protected female infants more than male infants, behaviours common in female-bonded species. Our study shows the ever-changing dynamics of maternal care related to infant age and highlights the role of the mother’s parity and rank in this process.
