Guenons, encompassing a variety of species within the tribe Cercopithecini, represent one of the most diverse and colorful groups of African monkeys. Found across sub-Saharan Africa, these primates exhibit a wide range of adaptations that enable them to thrive in various habitats, from rainforests to savannas.

The social structures of guenons are predominantly characterized by single-male/multi-female groups, where a dominant male leads and protects a group of females and their offspring from rival males and predators. This social organization facilitates the control of resources and ensures the dominant male’s reproductive success. However, exceptions to this rule exist, as seen in species like the African green monkey (Chlorocebus aethiops) and De Brazza’s monkey (Cercopithecus neglectus), which exhibit more flexible social systems, including multi-male groups or solitary behaviors.

Many guenon species possess long, often brightly colored tails that serve more than just aesthetic purposes. These tails are equipped with a specialized network of veins and arteries, a unique adaptation that helps regulate body temperature by mitigating heat loss in colder environments. This physiological adaptation underscores the guenons’ ability to adapt to varying climatic conditions across Africa.

Infanticide, the killing of infants within the group, is a distressing behavior observed in many Cercopithecus species. This behavior is often driven by incoming males who take over a group and seek to eliminate the offspring of their predecessors to bring the females back into estrus sooner. This grim reality can impact the population dynamics and growth of guenon groups.

Furthermore, the susceptibility to diseases varies significantly among guenon species, affecting their conservation status and management. Understanding these differences is crucial for developing effective conservation strategies that address each species’ specific health threats.
