Life history of captive gray-cheeked mangabeys: Physical and sexual development

Résumé

Ontogeny refers to every aspect of the development of an individual. In this respect growth and sexual maturation are useful life-history parameters that can be correlated with developmental features of social behavior. In this paper, I analyze body-weight growth and sexual maturation in captive gray-cheeked mangabeys (Cercocebus albigena). I also describe the development of external morphological characteristics, used as “physical markers.” Body-weight growth is analyzed in 15 males and 7 females. Individual weight velocity curves for animals of both sexes showed an, early peak around 2 years of age. Males had a later growth spurt, peaking between 4 and 6 years of age. Females showed no clear second growth acceleration (spurt), but they experienced an interruption of their weight growth deceleration between 3 and 5 years of age, which is generally coincident with puberty. In females there is a close relationship between weight and the occurrence of the first swelling of their sexual skin. These developmental parameters are compared to those described in baboons and macaques.
