Offspring Protection by Male Mandrills, Mandrillus Sphinx
Most mammals are characterized by a lack of parental care by the male sex. This is particularly true in highly polygynous, sexually selected species and species in which fathers remain only weakly associated with their offspring. Here we report observations suggesting the existence of male parental care in the mandrill (Mandrillus sphinx, Primates: Cercopithecinae), one of the most sexually dim...
متن کاملGenetic diversity and reproductive success in mandrills (Mandrillus sphinx).
Recent studies of wild animal populations have shown that estimators of neutral genetic diversity, such as mean heterozygosity, are often correlated with various fitness traits, such as survival, disease susceptibility, or reproductive success. We used two estimators of genetic diversity to explore the relationship between heterozygosity and reproductive success in male and female mandrills (Ma...
متن کاملSocial Structure of a Semi-Free Ranging Group of Mandrills (Mandrillus sphinx): A Social Network Analysis
The difficulty involved in following mandrills in the wild means that very little is known about social structure in this species. Most studies initially considered mandrill groups to be an aggregation of one-male/multifemale units, with males occupying central positions in a structure similar to those observed in the majority of baboon species. However, a recent study hypothesized that mandril...
متن کاملLife history in male mandrills (Mandrillus sphinx): physical development, dominance rank, and group association.
We assess life history from birth to death in male mandrills (Mandrillus sphinx) living in a semifree-ranging colony in Gabon, using data collected for 82 males that attained at least the age of puberty, including 33 that reached adulthood and 25 that died, yielding data for their entire lifespan. We describe patterns of mortality and injuries, dominance rank, group association, growth and stat...
متن کاملPrimary simian immunodeficiency virus SIVmnd-2 infection in mandrills (Mandrillus sphinx).
Mandrills are the only nonhuman primate (NHP) naturally infected by two types of simian immunodeficiency virus (SIV): SIVmnd-1 and SIVmnd-2. We have already reported that the high SIVmnd-1 replication during primary infection contrasts with only transient changes in CD4+ and CD8+ cell counts. Since early virus-host interactions predict viral control and disease progression in human immunodefici...
