| [vocal behavior of adult males and superspecific organization in polyspecific troops of monkeys]. | analysis of the vocal behaviour of adult males from different species of cercopithecus monkeys in a polyspecific troop shows important species differences, which suggest a superspecific organization upon which the extraordinary stability of certain polyspecific associations can depend. in the community studied, the male cercopithecus pogonias generally controlled the formation and disbanding of polyspecific troops, coordinated their movements and the spacing between troops, while cercopithecus c ... | 1983 | 6684083 |
| note on drill (mandrillus leucophaeus) ecology and conservation status in korup national park, southwest cameroon. | we report preliminary findings on drill population ecology, feeding ecology, primate associations and conservation status in korup national park, cameroon, based on analysis of data collected during 1,346 km (620 field hours) of trail patrols from february to june 2006. we encountered drills on 25 occasions and collected 304 fecal samples. group size was estimated on four occasions (> or =25, > or =40, > or =67, > or =77), and multiple males were heard emitting the characteristic two-phase grunt ... | 2008 | 17922527 |
| extensive survey on the prevalence and genetic diversity of sivs in primate bushmeat provides insights into risks for potential new cross-species transmissions. | to evaluate the risk of cross-species transmissions of sivs from non-human primates to humans at the primate/hunter interface, a total of 2586 samples, derived from primate bushmeat representing 11 different primate species, were collected at 6 distinct remote forest sites in southeastern cameroon and in yaoundé, the capital city. siv prevalences were estimated with an updated siv lineage specific gp41 peptide elisa covering the major part of the siv diversity. siv positive samples were confirme ... | 2010 | 19393772 |
| [cytogenetic study of cercopithecus wolfi, cercopithecus erythrotis and a hybrid cercopithecus ascanius x cercopithecus pogonias grayi]. | the karyotypes of two species of cercopithecus, c. wolfi and c. erythrotis, as well as that of a hybrid c. ascanius x c. pogonias grayi, are described and compared. the karyotype of c. erythrotis is similar to that of c. ascanius and c. cephus described previously. the karyotypes of c. wolfi and c. p. grayi differ by a single inversion. the karyotype of the hybrid shows that the two parental species differ by five rearrangements, three fissions and two inversions, an observation in agreement wit ... | 1985 | 3876066 |
| cytogenetic study of cercopithecus pogonias grayi x cercopithecus ascanius katangae hybrids. | the g-banded karyotypes of a male and a female hybrid born of the cross between a cercopithecus pogonias grayi (2 n = 72 xy) and a c. ascanius katangae (2 n = 66 xx) are reported. the constant chromosome number 2 n = 69 of both the male and female hybrids equals the arithmetic mean of the parental chromosome. a correlation between the hybrid karyotypes and those of their parents is proposed. the typical acrocentric autosomes of c. pogonias grayi are found again in the offspring. | 1982 | 7129256 |
| cytogenetic study of a cercopithecus pogonias grayi x cercopithecus mona mona hybrid. | the g- and c-banded karyotypes of hybrid born of the cross between a male cercopithecus pogonias grayi (2 n = 72 xy) and a female c. mona mona (2 n = 68 xx) are reported. the chromosome number is 2 n = 70 and equals half the total number of parental chromosomes. a correlation between the hybrid karyotype and those of its parents is proposed. the typical autosomes of c. pogonia grayi are again found in the young hybrids. | 1982 | 7095658 |
| the targeted sequencing of alpha satellite dna in cercopithecus pogonias provides new insight into the diversity and dynamics of centromeric repeats in old world monkeys. | alpha satellite is the major repeated dna element of primate centromeres. specific evolutionary mechanisms have led to a great diversity of sequence families with peculiar genomic organization and distribution, which have till now been studied mostly in great apes. using high throughput sequencing of alpha satellite monomers obtained by enzymatic digestion followed by computational and cytogenetic analysis, we compare here the diversity and genomic distribution of alpha satellite dna in two rela ... | 2018 | 29860303 |
