Primate Distribution

Primates are found primarily in tropical regions in 92 countries around the world

Neotropics:

New World monkeys

Madagascar:

Lemurs (prosimian)

Asia:

Lorises (prosimian) Tarsiers (prosimian) Old World monkeys Gibbons/siamangs (lesser apes) Orangutans (great apes)

Africa:

Galagos (prosimian) Pottos (prosimian) Old World monkeys Gorillas (great ape) Chimps/bonobos (great ape)

Early prosimians

Primates – General Characteristics

The following apply to most primates:

• Opposable first digit on hands and feet • Social animals • Arboreal part or all of the time • Color vision • Omnivorous

DeBrazza’s guenons

Primates – General Characteristics

• Forward-facing eyes for stereoscopic vision (ability to judge distance) • Five digits on each limb, usually with nails • Longer gestation, reduced number of offspring • Increased complexity of brain

Prosimians

(

Includes:

lemurs (Madagascar), lorises (Asia), tarsiers (Asia), pottos and bushbabies/galagos (Africa) • Primarily nocturnal • Excellent sense of smell • Smaller brains than other primates

Monkeys

Includes

(among others): marmosets, tamarins, macaques, howler monkeys, capuchins, baboons, colobus monkeys, mandrills, spider monkeys • Primarily diurnal • Have some form of tail • Fore and hindlegs similar in length

Old World & New World Monkeys

New World

• Inhabit neotropics in Mexico and South and Central America • Some have prehensile tails • Wide, sideways-facing nostrils

Old World

• Native to Africa and Asia • Do not have prehensile tails • Nostrils close together • Toughened rump patches

PRIMATES Social Structure and Behavior

Social Behavior of Primates

Primates are social animals • Only a few species are more solitary (orangutans, tarsiers, galagos)

Social Behavior of Primates

Strong mother-infant bond throughout the slow maturation period, during which significant learning occurs

Social Strategies of Primates

Social organization is complex and dynamic, influenced by: - age, gender, kinship, dominance ranking - short- and long-term alliances

Social Strategies of Primates

Social strategies of prosimian and monkey species at Woodland Park Zoo: •

Prosimians

Red ruffed lemurs

– social structure variable: ♀ + ♂ , or multi ♀ + multi ♂ , 5 to 16 in group – diurnal, little sexual dimorphism, ♂ dominant over ♀♀ groups – nocturnal lemurs are more solitary than diurnal lemurs

Monkeys

Tamarins

: only dominant ♀ breeds, ♂ dominant to ♀ , 5 to 8 in group •

Macaques

: ♂ + multi ♀ or ♂♂ +multi ♀ , 4 to 30 in group •

Patas monkeys

: ♂ +multi ♀ , 5 to 34 in group, ♀♀ boundary disputes but ♂ do not join in, engage in ♀ remain with group but disperse, allomothering ♂ •

Colobus monkeys

: ♂ +multi ♀ (males have short tenure – 2 years), 7 to 11 in group, allomothering common

Primates – Communication

Social interactions require a variety of modes of communication: • Olfactory – scent marking, pheromones for sexual interaction • Tactile – grooming, touching • Visual – facial expression, tail position, body posture, piloerection, hand gestures • Auditory – calls and vocalizations

Primates – Tool Use

• A tool is an object that can be manipulated to complete a task • Apes are capable of altering objects to facilitate a task (tool making) • All of the great apes have been observed using tools in the wild; bonobos, chimpanzees and orangutans have been observed making tools

Primates – Culture

• Culture is considered to be a set of behavioral traits passed on through learning • Culture in apes is reflected through variations between populations of apes in: – Hunting behaviors – Tool-making and tool use • Juveniles often learn behaviors from adults, observing and practicing over a long period of time

Threats to Primates

• Deforestation • Hunted for meat and skins • Captured for pet trade • Killed in retribution for raiding crops • Susceptible to human diseases • Parts used in traditional medicine

More to learn!

• New species are being discovered and new information is uncovered about primate behavior every year.

• This understanding can inspire deeper appreciation and protection for the world’s primates.
