Previous research on semifree-ranging mandrills has shown that the degree of secondary sexual development differs among adult males. Whilst some males were social, brightly colored, had large testes and high levels of plasma testosterone; other males...

Reproductive parameters and maternal investment in mandrills (Mandrillus sphinx). (2002)
Journal Article

14 years of reproductive data are reported for semifree-ranging mandrills (Mandrillus sphinx) in Gabon. Relationships between female rank, age and parity and reproductive strategies are explored. Most births (61% of 132) occurred during the wet seaso... Read More about Reproductive parameters and maternal investment in mandrills (Mandrillus sphinx)..

Two semifree-ranging mandrill groups, inhabiting large, naturally rainforested enclosures in Gabon, were studied to measure morphological, endocrine, and behavioral changes that occurred when adult males rose, or fell, in dominance rank. Gaining alph... Read More about Changes in the secondary sexual adornments of male mandrills (Mandrillus sphinx) are associated with gain and loss of alpha status..

Previous studies of semifree-ranging mandrills identified two morphological and social variants of the adult male, based on behavioral and secondary sexual characteristics. Fatted males are social, with highly developed sex skin coloration, large tes...

We present body mass (N = 419) and crown-rump length (CRL, N = 210) measurements from 38 male and 49 female mandrills born into a semifree-ranging colony in order to describe growth from birth to adulthood, and to investigate maternal influences upon...

Male mandrills (Mandrillus sphinx) have spectacular secondary sexual adornments. These include red and blue sexual skin on the face, rump, and genitalia; a sternal scent-marking gland; and a "fatted" rump. Mandrills are seasonal breeders, and in othe...
