Monkey species will become "Ëœincreasingly at risk of extinction' because of global warming, according to new research. It reveals that populations of monkeys and apes in Africa that depend largely on a diet of leaves may be wiped out by a rise in annual temperatures of two degrees Celsius. The study by researchers from Bournemouth University, Roehampton University and the University of Oxford suggests that the species most at risk are the already endangered gorillas and colobine...

The teeth of some apes are formed primarily to handle the most stressful times when food is scarce, according to new research performed at the National Institute of Standards and Technology (NIST). The findings imply that if humanity is serious about protecting its close evolutionary cousins, the food apes eat during these tough periods"”and where they find it"”must be included in conservation efforts. The interdisciplinary team, which brought together anthropologists from George...

Chemical identifiers secreted from the genital glands of lemurs, allow them to avoid incest and also to engage in nepotism. Researchers writing in the open access journal BMC Evolutionary Biology have identified the smells used by both male and female ring-tailed lemurs to advertise their family ties. Christine Drea from Duke University, North Carolina, USA, worked with Marylne Boulet and Marie Charpentier from the same university to study the primate's scent secretions. She said, "We sampled...

The world's largest species of monkey 'chooses' mates with genes that are different from their own to guarantee healthy and strong offspring, according to a new research study. The results obtained from mandrills, a species closely related to humans, support the disputed theory that humans are attracted to those with a dissimilar genetic make up to maintain genetic diversity. Female mandrills are more likely to reproduce with males whose genes are complementary, possibly because they 'smell...

Most of the linguistic functions in humans are controlled by the left cerebral hemisphere. A study of captive chimpanzees at the Yerkes National Primate Research Center (Atlanta, Georgia), reported in the January 2010 issue of Elsevier's Cortex (http://www.elsevier.com/locate/cortex), suggests that this "hemispheric lateralization" for language may have its evolutionary roots in the gestural communication of our common ancestors. A large majority of the chimpanzees in the study showed a...

Results may help to set conservation priorities for this critically endangered species The most extensive DNA study to-date of Africa's rarest monkey reveals that the species had an intriguing sexual past. Of the last two remaining populations of the recently discovered kipunji, one population shows evidence of past mating with baboons while the other does not, says a new study in Biology Letters. The results may help to set conservation priorities for this critically endangered species,...

Two Penn State University researchers have carried out one of the first-ever analyses of the effects of global warming on endangered primates. This innovative work by Graduate Student Ruscena Wiederholt and Associate Professor of Biology Eric Post examined how El Niño warming affected the abundance of four New World monkeys over decades. The research will be published on 28 October 2009 in the Royal Society journal Biology Letters, a fast-track journal of the Royal...

Music serves as a natural and non-invasive intervention for patients with severe neurological disorders to promote long-term memory, social interaction and communication. However, there is currently no plausible explanation of its neural basis for why and how music affects physical and psychosocial responses. Origins of music perception in humans may have their foundation in animal communication calls, as evidenced here in non-human primates. Many speech sounds and animal vocalizations, for...

U.S. evolutionary anthropologists say they've discovered spotted hyenas outperform primates on cooperative problem-solving tests. Duke University scientists led by Associate Professor Christine Drea said captive pairs of spotted hyenas (Crocuta crocuta) that needed to tug two ropes in unison to earn a food reward cooperated successfully and learned the maneuvers quickly with no training. And the researchers discovered experienced hyenas even helped inexperienced partners do the trick. When...

Spotted hyenas may not be smarter than chimpanzees, but a new study shows that they outperform the primates on cooperative problem-solving tests. Captive pairs of spotted hyenas (Crocuta crocuta) that needed to tug two ropes in unison to earn a food reward cooperated successfully and learned the maneuvers quickly with no training. Experienced hyenas even helped inexperienced partners do the trick. When confronted with a similar task, chimpanzees and other primates often require extensive...

Northern Muriqui, Brachyteles hypoxanthus
2014-04-17 13:48:56

The Northern Muriqui (Brachyteles hypoxanthus) is an endangered muriqui, meaning woolly spider monkey, species that is endemic to Brazil. It is rare among primates in that it shows egaliterian social relationships. It can be found in the Atlantic forest region of the Brazilian states of Espirito Santo, Minas Gerais, Bahia, and Rio de Janeiro. Muriquis are the biggest species of New World monkeys. The northern muriqui can grow up to 4.3 feet tall. This species feeds mostly on leaves and twigs,...

Sunda Slow Loris, Nycticebus coucang
2014-04-16 11:22:42

The Sunda slow loris (Nycticebus coucang), also known as the greater slow loris, is a primate that can be found in Singapore, western areas of Malaysia, southern areas of Thailand, and Indonesia. This species prefers to reside in tropical rainforests but can be found in other habitats. It was first discovered in 1770 by Dutchman Arnout Vosmaer, who described it as a sloth, and was later classified with all other known lorises as a single species. Today, the Sunda slow loris is one of nine...

Gray Langurs

Gray langurs, also known as Hanuman langurs, are members of the Semnopithecus genus, which contains seven species of Old World monkeys. Members of this genus can be found in a large range on the Indian subcontinent, preferring to reside in forested areas or semi-wooded areas at low or moderate elevations, although some species can be found as high as 13,000 feet above sea level. Until 2001, Semnopithecus entellus was the only species classified within this genus. When it was separated into...

Yellow-Tailed Woolly Monkey, Oreonax flavicauda
2014-04-10 14:40:56

The Yellow-Tailed Woolly Monkey (Oreonax flavicauda) is a New World monkey that is native to Peru. It is a rare primate species that is found only in the Peruvian Andes, in the departments of Amaxonas and San Martin, along with the bordering areas of La Libertad, Huanuco, and Loreto. This woolly monkey was, at first, under the Lagothrix genera with other woolly monkeys, but because of debatable primary sources, they have been placed under the Oreonax genera. This genus has been suggested to...

Primatology

Primatology is the study of primates that focuses on their behaviors and possible evolution. Those who practice this science, known as primatologists, focus on primates in the wild and in laboratory settings. There are many different sub-divisions of primatology that differ based on methodology and theory, but the two major branches are Western primatology and Japanese primatology. There share basic principles, but differ culturally and in many other regards. Western primatology originated...
