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...

The first ever pictures of the Horton Plains slender loris, a rare and endangered breed of primate that had long been thought extinct, have been captured by scientists at the Zoological Society of London (ZSL), according to a Monday press release from the conservation organization. According to the ZSL, there were only four sightings of this loris subspecies from 1939 through 2002, which led many scientists to believe that they had all died out. However, as part of the ZSL's "Edge of...

Global warming may present a threat to animal and plant life even in biodiversity hot spots once thought less likely to suffer from climate change, according to a new study from Rice University. Research by Amy Dunham, a Rice assistant professor of ecology and evolutionary biology, detailed for the first time a direct correlation between the frequency of El Niño and a threat to life in Madagascar, a tropical island that acts as a refuge for many unique species that exist...

Political and social chaos and a lack of international protections have put several species of rosewood trees in Madagascar in danger of becoming extinct from illegal logging, according to a policy forum paper in the latest issue of Science. "Forty-seven of Madagascar's 48 species of rosewood (Dalbergia) are found nowhere else in the world," said Duke University graduate student Meredith Barrett, the lead author on the May 27 article. Madagascar's military-backed change in leadership last...

GALVESTON, Texas, April 14 /PRNewswire-USNewswire/ -- Moody Gardens is proud to introduce pygmy slow loris twins born on March 22. Breeding of this species is often challenging and largely rare in captivity. In fact, this is only one of five pygmy slow loris births in captivity in North America over the past year. (Photo: http://www.newscom.com/cgi-bin/prnh/20100414/DC85838 ) "This is such an exciting event," said Paula Kolvig, assistant curator at Moody Gardens. "We have been...

A fossil that was celebrated last year as a possible "missing link" between humans and early primates is actually a forebearer of modern-day lemurs and lorises, according to two papers by scientists at The University of Texas at Austin, Duke University and the University of Chicago. In an article now available online in the Journal of Human Evolution, four scientists present evidence that the 47-million-year-old Darwinius masillae is not a haplorhine primate like humans, apes and monkeys, as...

Mankind's closest living relatives -- apes, monkeys, gorillas, and other primates -- are among the world's most endangered species and are on the brink of extinction unless urgent measures are taken to protect them, according to a Thursday report by conservation groups. Researchers from all over the world participated to create the top 25 most endangered primate species list. In all, nearly half of the 634 known primate species are considered to be threatened to some degree, said the...

A new model for primate origins is presented in Zoologica Scripta, published by the Norwegian Academy of Science and Letters and The Royal Swedish Academy of Sciences. The paper argues that the distributions of the major primate groups are correlated with Mesozoic tectonic features and that their respective ranges are congruent with each evolving locally from a widespread ancestor on the supercontinent of Pangea about 185 million years ago. Michael Heads, a Research Associate of the Buffalo...

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...

'Passive' mate guarding influenced evolution of lemur sizeWhen it comes to investigating mysteries, Sherlock Holmes has nothing on Rice University biologist Amy Dunham. In a newly published paper, Dunham offers a new theory for one of primatology's long-standing mysteries: Why are male and female lemurs the same size? In most primate species, males have evolved to be much larger than females. Size is an advantage for males that guard females to keep other males from mating with them, and...

Randrianasolo's Sportive Lemur, Lepilemur randrianasoloi
2012-08-08 09:32:17

Randrianasolo's sportive lemur (Lepilemur randrianasoloi) is also known as Bemaraha sportive lemur, and is native to western areas of Madagascar. The full extent of its range is not yet known, because this species is one of fifteen described in 2006, so more research is needed to define the boundaries of its range. It occurs in dry deciduous forests. Randrianasolo's sportive lemur can reach an average body length of up to 1.8 feet, including the tail. Because this lemur has only recently...

Sahamalaza Sportive Lemur, Lepilemur sahamalazensis
2012-08-08 09:26:25

The Sahamalaza sportive lemur (Lepilemur sahamalazensis) is native to the island of Madagascar, where its range is limited to the Sahamalaza Peninsula found in northwestern Madagascar. Because this area is a converging point for two types of habitats, including arid deciduous forests, this lemur resides in both primary and secondary forests. The Sahamalaza sportive lemur is a newly discovered species, along with 14 other members in the Lepilemur genus. Because of this, its taxonomic status...

Crowned Sifaka, Propithecus coronatus
2012-08-08 08:43:18

The crowned sifaka (Propithecus coronatus) is native to Madagascar, with a range that extends to the Mahavavy River in the southwest. The northeastern border of this range is the Betsiboka River. It has been reported that the crowned sifaka occurs in south and southeast Madagascar, which may broaden its range. It prefers to reside in arid deciduous forests in western Madagascar. The crowned sifaka can reach an average body length of 3.3 feet, with a tail length between 1.5 and 1.8 feet....

Aye-aye, Daubentonia madagascariensis

The aye-aye (Daubentonia madagascariensis) is a species of lemur that is native only to the island of Madagascar. This species is the only remaining member in the Daubentonia genus. Its range is slightly fragmented in some areas. It derives its scientific name from Louis-Jean-Marie Daubenton, a French naturalist, and from the island on which it was first discovered. Aye-ayes prefer a habitat within deciduous forests or rainforests, with most occurring in rainforests, but can inhabit...
