Discovery of organized, 3-D grid lays the groundwork for future investigations How do you build a brain? In the March 30 issue of Science a team of investigators presents a surprising answer, reporting their discovery of a remarkably simple organizational structure in the brains of humans and other primates. Employing sophisticated mathematical analysis of advanced imaging data, they found that the pathways carrying neural signals through the brain are arranged not in a disorganized tangle...

Studies in monkeys are unlikely to provide reliable evidence for links between social status and heart disease in humans Studies in monkeys are unlikely to provide reliable evidence for links between social status and heart disease in humans, according to the first ever systematic review of the relevant research. The study, published in PLoS ONE, concludes that although such studies are cited frequently in human health research the evidence is often "cherry picked" and generalisation of...

As large, carnivorous mammals, spotted hyenas are well known for their competitive nature; however, recent work suggests that their clan structure has similarities to some primate social systems such as those of the baboon and macaque. San Diego Zoo Global researchers have documented relatedness between individuals and how this factor appears to influence their social behaviors. "Understanding how animal social systems work is an important part of learning what we need to know to conserve...

Endangered African Monkey's DNA Suggests Troubles From Warming Climate
2012-03-01 04:47:35

University of Oregon scientist says drill face increasing threats from both climate change and hunters A rare and endangered monkey in an African equatorial rainforest is providing a look into our climatic future through its DNA. Its genes show that wild drills (Mandrillus leucophaeus), already an overhunted species, may see a dramatic population decline if the forest dries out and vegetation becomes sparser amid warming temperatures, researchers report. Looking for clues amid 2,076...

Philippine Tarsier Has Bat-Like Pitch
2012-02-08 10:19:09

One of the world´s smallest primates, the Philippine Tarsier (Tarsius syrichta), has the world´s highest pitched vocalization of any primate ever documented, according to a study published Wednesday. That call, however, is so high-pitched that it is inaudible to human ears. It is a big voice for such a small creature, no bigger than the size of a man´s hand. It shrieks out the vocalization as a warning of danger or a call to dinner. “Tarsiers are among only a...

'Extinct' Monkey Found In Borneo

[ Watch the Video ] Scientists report that they have rediscovered a species of primate in Borneo that was believed to be extinct or on the verge of extinction. The team has confirmed that Miller's Grizzled Langur, or Presbytis hosei canicrus, still exists and lives in an area where it was previously not known to inhabit. "Concern that the species may have gone extinct was first raised in 2004, and a search for the monkey during another expedition in 2008 supported the assertion that...

Why are the faces of primates so dramatically different from one another? UCLA biologists working as "evolutionary detectives" studied the faces of 129 adult male primates from Central and South America, and they offer some answers in research published today, Jan. 11, in the early online edition of the journal Proceedings of the Royal Society B. The faces they studied evolved over at least 24 million years, they report. "If you look at New World primates, you're immediately struck by...

Celebrities are channeling a distant relative with what Harper´s Bazaar describes as the latest trend in nail fashion for 2012: claws. But this may not be the first time primates traded their nails for claws. A new study co-authored by a University of Florida researcher examines the first extinct North American primate with a toe bone showing features associated with the presence of both nails and a grooming claw, indicating our primate ancestors may have traded their flat nails for...

Study Finds Macaques Value Friendship Over Family Bonds
2012-01-11 14:32:54

The bonds of friendship are stronger than the bonds of blood for crested macaque monkeys, according to a new study published online in the journal Animal Behaviour. The research, which was conducted by Jerome Micheletta and Dr. Bridget Waller of the University of Portsmouth's Department of Psychology, looked at gaze following -- the act of looking where a companion is looking -- among the primates. According to BBC News Science Reporter Victoria Gill, gaze following is highly valued in...

Image 1 - Pigeons Have Numerical Abilities Just Like Primates
2011-12-23 09:21:47

Researchers at University of Otago in New Zealand have found that pigeons are able to learn abstract rules about numbers, an ability that until now had been demonstrated only in primates. Scientists had trained rhesus monkeys in the 1990s to look at groups of items on a screen and rank them from lowest number of items to highest. It has already been known that pigeons know how to count, just like many other animals, including bees and other species of birds. In a study, published in the...

Brown Spider Monkey, Ateles hybridus
2014-04-28 09:58:59

Brown Spider Monkeys have long and thin limbs with their forelimbs being longer than their hind limbs. They also have a distinctive 75 centimeter long flexible and thin prehensile tail which at times acts like a fifth limb. The tip is hairless with ridged skin for better grip. All of these features of their body make it possible for them to climb trees and high elevations, hang and swing from one tree to another without having to lower themselves to the ground frequently. Their hands are...

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...
