| the banded karyotypes of macaca fuscata compared with cercocebus aterrimus. | the karyotypes of macaca fuscata and cercocebus aterrimus are compared after g, c and agnor banding. although it is often assumed that the 42-chromosome monkeys (species of the genera macaca, papio, and cercocebus) are identical at the chromosomal level, a number of clear and consistent differences between the karyotypes of these two taxa are described. these differences include one pericentric inversion and differences in staining intensity, particularly in centromeric and pericentromeric areas ... | 1983 | 6654268 |
| mutations in ccr5-coding sequences are not associated with siv carrier status in african nonhuman primates. | african monkeys can be naturally infected with siv but do not progress to aids. since mutations in the human ccr5 gene have been shown to influence susceptibility to hiv infection and disease progression, we have now investigated whether mutations in ccr5-coding sequences in african nonhuman primates can explain species-specific differences in susceptibility to lentiviral infection. the animals studied comprise chronically infected monkeys corresponding to four natural hosts of siv (cercopithecu ... | 1999 | 10408730 |
| a novel simian immunodeficiency virus from black mangabey (lophocebus aterrimus) in the democratic republic of congo. | in order to understand primate lentivirus evolution, characterization of additional simian immunodeficiency virus (siv) strains is essential. here, an siv from a black mangabey (lophocebus aterrimus) originating from the democratic republic of congo was analysed phylogenetically. the monkey had cross-reactive antibodies against human immunodeficiency virus type 1 (hiv-1) and hiv-2. the viral pol region sequence was amplified by nested pcr and sequence analysis confirmed that it was related to kn ... | 2005 | 15958675 |
| evidence for the consumption of arboreal, diurnal primates by bonobos (pan paniscus). | we present evidence for the consumption of a diurnal, arboreal, group living primate by bonobos. the digit of an immature black mangabey (lophocebus aterrimus) was found in the fresh feces of a bonobo (pan paniscus) at the lui kotale study site, democratic republic of congo. in close proximity to the fecal sample containing the remains of the digit, we also found a large part of the pelt of a black mangabey. evidence suggests that the lui kotale bonobos consume more meat than other bonobo popula ... | 2009 | 19058132 |
| surgical treatment of recurrent rectal prolapse in an adult female black-crested mangabey (lophocebus aterrimus) by colopexy. | a 13-y-old, multiparous female black-crested mangabey (lophocebus aterrimus) underwent surgical treatment for chronically recurring rectal prolapse by laparotomy and subsequent colopexy. initially, a laparoscopic approach was attempted but was converted to an open approach after intraabdominal adhesions were noted. the colopexy was performed through a ventral midline incision, with no complications intraoperatively or postoperatively. the predisposing factors responsible for the development of t ... | 2018 | 29460725 |
| assessment and preservation of liquid and frozen-thawed black crested mangabey (lophocebus aterrimus) spermatozoa obtained by transrectal ultrasonic-guided massage of the accessory sex glands and electroejaculation. | the black crested mangabey (lophocebus aterrimus) is an african monkey listed as near threatened by the iucn and in captivity the population is limited to 34 males. the aim of this study was to evaluate two black crested mangabey males, maintained in captivity in a zoological garden and suspected of infertility, with a complete examination of their genital tract using ultrasonography, followed by recovery of semen using transrectal ultrasonic massage of the accessory sexual glands (tumasg) and e ... | 2019 | 31635773 |
| the socioecology of the black mangabey (cercocebus aterrimus) near lake tumba, zaire. | socioecological data were gathered in a two-year study of black mangabey monkeys in a secondary forest on the west bank of lake tumba, zaire. the mangabeys of the study area lived in multi-male, multi-female groups numbering between 14 and 19 individuals. they were completely arboreal, fed mostly on fruit and nuts, and frequently were associated with other species of arboreal monkeys. their predators were human hunters and the crowned hawk-eagle. the primary vocalizations of black mangabeys were ... | 1987 | 31973502 |
| taxonomic assessment of the allopatric gray-cheeked mangabey (cercocebus albigena) and black mangabey (c. aterrimus): comparative socioecological data and the species concept. | a brief review of past taxonomic assessments of the allopatric gray-cheeked mangabey (cercocebus albigena) and the black mangabey (cercocebus aterrimus) is presented. on the basis of pelage, cranial, and biomolecular morphology, aterrimus and albigena have been lumped together in the same species-group, superspecies, subgenus, or species by various systematists over the years. a comparison of the available socioecological data on the two forms supports their close taxonomic association, as they ... | 1987 | 31973509 |
| census, habitat preference, and polyspecific associations of six monkeys in the lomako forest, zaire. | this paper reports preliminary data on a number of poorly known cercopithecids inhabiting the lomako forest, zaire. data include those on density, biomass, group size, the relationship between group type (mono vs. polyspecific) and forest type (mixed primary, secondary, monodominant primary, and swamp), and vertical stratification. species examined are colobus angolensis, cercocebus aterrimus, cercopithecus wolfi, cercopithecus ascanius, cercopithecus neglectus, and allenopithecus nigroviridis. ... | 1994 | 31936961 |

| bringing up baby: developmental simulation of the adult cranial morphology of rungwecebus kipunji. | rungwecebus kipunji is a recently discovered, critically endangered primate endemic to southern tanzania. although phenetically similar to mangabeys, molecular analyses suggest it is more closely related to papio or possibly descended from an ancient population of baboon-mangabey hybrids. at present, only a single kipunji specimen, an m1-stage juvenile male, is available for study; thus, the cranial morphology of the adult kipunji is unknown. in this study, we used developmental simulation to es ... | 2010 | 19967768 |
| brief communication: enamel thickness and durophagy in mangabeys revisited. | the documentation of enamel thickness variation across primates is important because enamel thickness has both taxonomic and functional relevance. the old world monkeys commonly referred to as mangabeys have figured prominently in investigations of feeding ecology and enamel thickness. in this article, we report enamel thickness values for four mangabey taxa (cercocebus atys, cercocebus torquatus, lophocebus aterrimus, and lophocebus albigena), offer revised interpretation of the significance of ... | 2011 | 22101774 |
| direct inoculation of simian immunodeficiency virus from sooty mangabeys in black mangabeys (lophocebus aterrimus): first evidence of aids in a heterologous african species and different pathologic outcomes of experimental infection. | a unique opportunity for the study of the role of serial passage and cross-species transmission was offered by a series of experiments carried out at the tulane national primate research center in 1990. to develop an animal model for leprosy, three black mangabeys (bkms) (lophocebus aterrimus) were inoculated with lepromatous tissue that had been serially passaged in four sooty mangabeys (sms) (cercocebus atys). all three bkms became infected with simian immunodeficiency virus from sms (sivsm) b ... | 2004 | 15479792 |
