Past Influences On Biodiversity In Madagascar
2012-07-25 10:35:30

Brett Smith for redOrbit.com - Your Universe Online While human activity is usually identified as the primary threat to biodiversity through the loss of species, a new study published in the journal Proceedings of the Natural Academy of Sciences (PNAS) focused on identifying pre-human causes of pressures that threaten endangered species. The latest research focused on Madagascar, which is world-renowned for its biodiversity and has been plagued by deforestation and the destruction of...

Madagascar Lemurs Threatened With Extinction
2012-07-13 09:14:08

Lawrence LeBlond for redOrbit.com - Your Universe Online More than a hundred species of lemur are found on Madagascar, a small island in the Indian Ocean just southeast of the African mainland, and a new study suggests that many of these social primates are on their way out. According to the conservation group International Union for the Conservation of Nature (IUCN), as many as 90 percent of the 103 species of lemur found on Madagascar should be listed on the Red List of Threatened...

Extinctions Drive Ongoing 'Ecological Retreat' By Surviving Species
2012-05-26 04:51:51

Brett Smith for Redorbit.com A new study on the extinctions of species suggests that the disappearance of one species does not necessarily allow remaining competitor species to thrive by filling in the vacuum. University of Cincinnati researchers studying lemur extinctions over the past 2,000 years, found that changes in inter-species dynamics via extinction can force that remaining species to go into a so-called “ecological retreat” that may not be suited to the extant...

Image 1 - Scratching The Surface Of Social Interaction
2012-03-26 02:28:28

It can be difficult to uncover the behavior of small, shy, nocturnal primates like the brown mouse lemur (Microcebus rufus), especially in the dense rainforests of Madagascar where this lemur lives. New research published in BioMed Central's open access journal BMC Ecology shows that the social interactions of brown mouse lemurs can be monitored by mapping the transfer of tagged lice. Brown mouse lemurs are the only known host of the parasitic louse Lemurpediculus verruculosus. The lice...

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...

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...

Madagascar Wildlife Facing Threat Of Illegal Hunting
2011-12-16 05:48:26

Researchers have found that illegal hunting of protected species in Madagascar could cause an urgent threat to the country's globally important biodiversity. The scientists said that hunting of protected species in eastern Madagascar is increasing due to rapid social change. "Our observations suggest that young men have more available cash and leisure time due to the transition from subsistence farming to panning for gold, and they spend more time in local bars, eating fried meat snacks...

From hot pink to traditional French and Lady Gaga's sophisticated designs, manicured nails have become the grammar of fashion. But they are not just pretty "” when nails appeared on all fingers and toes in modern primates about 55 million years ago, they led to the development of critical functions, including finger pads that allow for sensitive touch and the ability to grasp, whether it's a nail polish brush or remover to prepare for the next trend. In a new study co-authored by...

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 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...
