Male age and reproductive behaviour in sooty mangabeys, Cercocebus torquatus atys
Animal Behaviour, 1991Abstract The aim of this study was to quantify and characterize copulatory behaviour in sooty mangabeys and to assess differences based on male age. Sexual behaviour, maked by penile erection, intromission and thrusting, began before 1 year of age and the frequency of this behaviur was highest in adolescent males. In fact, these males (1–4 years old)

The accuracy and precision of sexual swellings and fecal steroids as measures of ovarian function and the periovulatory period were compared in 4 sexually mature, individually housed, sooty mangabey females. Fecal samples were collected daily over a 10-week period during the normal breeding season.

Affiliative behavior of adult female sooty mangabeys (Cercocebus atys)
American Journal of Primatology, 1988AbstractA 14‐month study of 30 adult female members of a captive group of sooty mangabeys investigated their affiliative interactions with group members of varying age and sex. The adult females preferentially affiliated with other adults and interacted less than expected with immature group members.

The absence of a matrilineally based dominance system in sooty mangabeys, Cercocebus torquatus atys
Animal Behaviour, 1994Abstract Abstract. Sooty mangabeys, Cercocebus torquatus atys, exhibit a dominance hierarchy that is unrelated to matrilineal kinship except during the first years of life. A cross-sectional analysis showed that young mangabeys, from infancy to approximately 3 years of age, rank just below their mothers, although thereafter generally attain higher ...

Spontaneous gastric carcinomas in sooty mangabeys (Cercocebus atys).
Comparative medicine, 2012Sooty mangabeys (Cercocebus atys) are native to West Africa and are a natural host of SIV, which is implicated in the origin of HIV2. They have been used in studies of AIDS pathogenesis, leprosy, immune responses, reproductive biology, and behavior. Spontaneous tumors have rarely been reported in this species.

Single cortical units with narrow spectral sensitivity in monkey (Cercocebus torquatus atys)
Vision Research, 1962Abstract The narrow spectral sensitivity curves of single units in the area of central retinal representation in monkey cortex are described. Responses to about 60 to 100 mμ were usual. There were hardly any responses to white. The responses were with one or two spikes whose latency and change in latency with intensity were different for units ...

Experimental leprosy in the mangabey (Cercocebus atys): necropsy findings.
International journal of leprosy and other mycobacterial diseases : official organ of the International Leprosy Association, 1985A mangabey monkey (Cercocebus atys) was inoculated intravenously and intracutaneously with acid-fast bacilli (AFB) from a mangabey with spontaneously acquired leprosy. It developed generalized lepromatous leprosy and died 46 months after inoculation.

Infanticide risk and infant defence in multi-male free-ranging sooty mangabeys, Cercocebus atys
Behavioural Processes, 2010For years, infanticide by males was thought to be unlikely in multi-male primate species. Recent studies have, however, presented evidence of infanticide in such species and a recent model by Broom and colleagues predicts that males' age and rank influence the occurrence of infanticide: youngest and highest-ranking immigrant males are more likely to ...

Cerebral amyloid angiopathy in an aged sooty mangabey (Cercocebus atys).
Comparative medicine, 2014A 26-y-old male sooty mangabey (Cercocebus atys) was found at necropsy to have a moderate degree of cerebral amyloid β (Aβ) angiopathy in superficial and parenchymal blood vessels of the brain. Senile (Aβ) plaques were absent, as were neurofibrillary tangles and other signs of neurodegeneration.
