The role of dominance in the social and sexual behavior of infrahuman primates. Dunbar RIM. These large groupings can be determined by various ecological needs such as predation avoidance, optimal habitat use and foraging, male mate defense and infanticide avoidance (Dunbar, 1983).

Geladas and baboons are closely related primates living in socially complex groups that differ dramatically in group size—geladas routinely associate with more than 10 … The male's relationship with his females. Like the less social primates, many of these mammals live in small groups or have fission–fusion type social systems (the default way to defuse social stresses), but a few (elephants, dolphins, equids) have primate-like bonded social systems and some of these are multilevel societies like those of the gelada and chimpanzees (Hill et al., 2008). DeVore (ed. But now, his reign is under siege. Gelada baboon social structure is also especially interesting because it contrasts sharply with a closely related species of baboon — the hamadryas baboon. In:Primate Behavior,I. Genet. ), Holt, Rinehart, & Winston, New York, pp. Males also form bachelor groups consisting of about 15 individuals. The Gelada baboon are only found in the high grassland of the central Ethiopian plateau, which is the only place they can be hunted. A key difference is that gelada males form long-term bonds with the 2–12 females in their harem-like reproductive unit, while chacma males primarily form temporary consortships with females. The leader of a harem is usually older than nine years old and can be overthrown by another male baboon through a fight that can sometimes last up to three days. Gelada baboon social structure is also especially interesting because it contrasts sharply with a closely related species of baboon — the hamadryas baboon. In fact Gelada social studies have been of great relevance in analyzing the evolution of human social behavior.

Adult male and female olive baboons had close social interaction among each other. We use this common name for all the monkeys from the family of primates called Cercopithecidae. To determine the group structure, once gelada monkey group was spotted, they were categorized based on social organization and classified into OMUs, AMUs, and bands (Zewdu et al.

Although most gelada social interactions occur within the reproductive units, a band of geladas travels, eats, and sleeps together, thus making them a suitable model system for investigating the effects of social interactions on the microbiome within the larger context of an animal society. Here, we explore whether dominance rank and kinship predict female social bonds in a wild population of geladas ( Theropithecus gelada ), a species that differs from other cercopithecines in that the individuals have 1) an unusual modular social system, 2) low food competition, and 3) extraordinarily high levels of social tolerance.

To better understand the function of vocal complexity within primates, we compared two closely related primates (chacma baboons and geladas) that differ in their ecology and social structures. Particle size in gelada is similar to that for zebra, larger than that for cattle and smaller than Collier-MacMillan, London. There is a large troop of Gelada baboons here at Edinburgh Zoo and, like many primates, they have a complex social structure. The following communicative sets were found: (1) “female-sexual releasing”, (2) “greeting and approaching releasing” versus “groom releasing”, (3) “austostimulation releasing” versus “male-sexual releasing”, (4) “fight releasing”, and (5) “conflict”.
