The patas monkey (Erythrocebus patas), also known as the wadi monkey or hussar monkey, is a ground-dwelling monkey distributed over semi-arid areas of West Africa, and into East Africa. It is the only species classified in the genus Erythrocebus. Recent phylogenetic evidence[citation needed] indicates that it is the closest relative of the vervet monkey (Chlorocebus aethiops), suggesting nomenclatural revision.[verification needed]

Taxonomy
There is some confusion surrounding the number of valid subspecies, with some listing four,[3] and others listing two; the western Erythrocebus patas patas (Common patas; with a black nose) and the eastern Erythrocebus patas pyrrhonotus (Nisnas; with a white nose). Others, however, have suggested that at least some of the features used to separate these subspecies are merely variations in the female's facial pattern during pregnancy.[1] On the other hand, the change in the nose during pregnancy occurs only in the West African populations.
Physical description
The patas monkey grows to 85 cm (33 in) in length, excluding the tail, which measures 75 cm (30 in). Adult males are considerably larger than adult females. Reaching speeds of 55 km/h (34 mph), it is the fastest runner among the primates.[4]
Behavior
The patas monkey lives in multi-female groups of up to 60 individuals (although much larger aggregations have been reported). The group contains just one adult male for most of the year.[5] During the breeding season, there are multi-male influxes into the group. Once juvenile males reach sexual maturity (around the age of four years) they leave the group, usually joining all-male groups. The adult females in the group initiate movement of the group with the male following their lead.[5]
Female social organization
Variation in the female social structure of patas monkeys has been observed across different populations. This variation may be dependent on food resources, as conflict between individuals is often a result of competition for limited resources. Higher rates of conflict over dense, but limited, food, such as fruit bushes, is associated with more stable, well defined dominance hierarchies than habitats with more diffuse resources, such as insects. Variation in the availability of these resources has been associated with variation in dominance hierarchies among females.
Conflict among females has also shown the presence of recognition among matrilineal relatives. It has been observed that, shortly after conflicts among two females, patas monkeys often act differently toward each other than if they had not been in conflict. Females often “reconcile” with each other by activities such as sitting together and grooming. While this reconciliatory behavior is observed even between unrelated individuals, it is most common among matrilineal relatives. Dominance structure has relatively little effect on the probability of reconciliation occurring, except that the alpha-female is the least reconciliatory of the females. Affiliation toward matrilineal relatives is common in other primates as well, such as vervet monkeys.
Male social organization
Mating in patas monkeys is seasonal and occurs during the wet season.[citation needed] During periods when females are not receptive, relatively stable groups with one adult resident male and several females are the norm. This leaves an excess of males that either form all male groups or live on their own. During the mating season, resident males may be chased away by invading solitary males. This usually results in the formation of multi-male, multi-female groups shortly thereafter, as more males invade a group. The new resident male does not chase away subordinate invading males, but rather focuses of mating with females. At the end of the mating season, one-male, multi-female groups stabilize. One male remains as the resident male and chases other males away. In some instances, submissive males are tolerated by the resident male for short periods of time; however, they rarely remain in the group for more than several days.
Young males have been observed to leave their natal groups anywhere from two to four years of age. However, one study showed that most juveniles left before they were three, which is before most males reach sexual maturity. This contrasts with an earlier study in which juveniles were observed to leave later, at sexual maturity, indicating that there may be variation between groups. The reason young males leave their natal group is also contested. Dominant males have been observed to act aggressively toward younger males in captivity. However, observations of wild patas monkeys has shown young males leaving the group in which they were born without any aggressive behavior from the adult male. The juveniles, in the time shortly before they leave, spend increasingly less and less time with the adult females in the group. However, juvenile males do not change the amount of time they spend near the adult male. This may indicate weakening of matrilineal ties, rather than male aggression, as the main reason juveniles disperse from their natal group.
Alarm calls
Patas monkeys have several distinct alarm calls that warn members in the group of predators. Different alarm calls are given by different group members (i.e. adult females, adult males, juveniles, etc.) and certain alarm calls are distinctive of different types of predators. Unlike other primates, patas monkeys rarely take refuge from predators in trees. This is most likely the due to the relatively sparse tree cover in patas monkey habitats. While patas monkeys usually run on the ground away from predators, individuals have been observed to attack predators such as jackals and wildcats. This behavior has been observed in both males and females.
Habitat
The patas monkey avoids dense woodlands and lives in more open savanna and semi-deserts. The patas monkey has a remarkably high reproductive rate, perhaps as an evolutionary response to the high adult mortality rates associated with this strongly terrestrial lifestyle.[11]
Diet
The patas monkey feeds on insects, gum, seeds, and tubers, a diet more characteristic of much smaller primates.[12]
