Pass the chips and hand over the remote. In a study involving the first-ever daily energy expenditure measurements in apes, a researcher from Washington University in St. Louis and his team have determined that orangutans living in a large indoor/outdoor habitat used less energy, relative to body mass, than nearly any eutherian mammal ever measured, including sedentary humans. All this despite activity levels similar to orangutans in the wild. "It's like finding a sloth in your family tree,"...

Hormonal contraceptives change the ways captive ring-tailed lemurs relate to one another both socially and sexually, according to a Duke University study that combined analyses of hormones, genes, scent chemicals and behavior. Contraception alters the chemical cues these scent-reliant animals use to determine genetic fitness, relatedness and individuality. And, as a sort of double whammy to birth-control efforts, male lemurs were shown to be less interested in females that were treated with...

Scientists have examined the fossilized remains of a small, extinct monkey that were recovered from an underwater cave in the Dominican Republic. Researchers believe the fossil is about 3,000 years old, but say the species itself could be very ancient. The find reveals clues about the origin of primates in the region. Dr Alfred Rosenberger from Brooklyn College in New York, led the examination of the monkey's bones. The results of the assessment are published in the Royal Society of...

Predatory trickery documented for the first time in wild felids in Americas In a fascinating example of vocal mimicry, researchers from the Wildlife Conservation Society (WCS) and UFAM (Federal University of Amazonas) have documented a wild cat species imitating the call of its intended victim: a small, squirrel-sized monkey known as a pied tamarin. This is the first recorded instance of a wild cat species in the Americas mimicking the calls of its prey. The extraordinary behavior was...

Using experiments involving a mechanical shaker and a robotic frog, researchers reporting online on May 20th in Current Biology, a Cell Press publication, have found new evidence that male red-eyed treefrogs communicate with one another in aggressive contests by using vibrations they send through their plant perches. The findings open the door to further study of what has been a neglected channel for vertebrate communication. "In the case of red-eyed treefrogs, tremulation displays in which...

Male physical competition, not attraction, was central in winning mates among human ancestors, according to a Penn State anthropologist. "There is sexual competition in many species, including humans," said David A. Puts, assistant professor of biological anthropology. Many researchers have considered mate choice the main operator in human sexual selection. They thought that people's mating success was mainly determined by attractiveness; but for men, it appears that physical competition...

Previously unknown species complicates understanding of African evolution It's in the teeth. An odd mosaic of dental features recently unearthed in northern Egypt reveals a previously undocumented, highly-specialized primate called Nosmips aenigmaticus that lived in Africa nearly 37 million years ago. Because it is only known from its teeth, the paleontologists who discovered it don't know what its body looked like, but the find likely represents an ancient African lineage whose discovery...

Regular exercise speeds learning and improves blood flow to the brain, according to a new study led by researchers from the University of Pittsburgh School of Medicine that is the first to examine these relationships in a non-human primate model. The findings are available in the journal Neuroscience. While there is ample evidence of the beneficial effects of exercise on cognition in other animal models, such as the rat, it has been unclear whether the same holds true for people, said senior...

DURHAM, N.C. -- A group of scientists who have studied the life history of primates for decades got to thinking about their own life histories and decided they had better do something to preserve their work for posterity. The conversation started after University of Wisconsin-Madison anthropologist Karen Strier experienced the unexpected deaths of two friends and academic colleagues "“ one a UW-Madison professor, the other a Brazilian graduate student. She approached Susan Alberts, a...

The fifth Howler Monkey census at the Smithsonian's Barro Colorado Island research station in Panama, organized by Katie Milton, professor in the department of Environmental Science, Policy & Management at the University of California, Berkeley, revealed that monkey numbers have not changed significantly since the first census 33 years ago. Long before dawn on March 19 and 20, Katie Milton and a group of stalwart volunteers, each armed with flashlight and compass, spread out into 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...

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...
