The ring-tailed lemur (Lemur catta), perhaps the most well-known of Madagascar’s endemic animals, is facing a “very high” risk of extinction in the wild. The Madagascar Section of the IUCN Primate Specialist Group reassessed the Red List status of ring-tailed lemurs and upgraded the species from Near-Threatened (2008) to Endangered (2012). Ring-tailed lemurs are facing […]

Like ancient humans, some lemurs slumber in caves
After playing, feeding, and socializing in trees all day, some ring-tailed lemurs (Lemur catta) take their nightly respite in caves, according to a new study in Madagascar Conservation and Development. The findings are important because this is the first time scientists have ever recorded primates regularly using caves (see video below). “The remarkable thing about […]
Review: Bird Sense: What it’s Like to be a Bird, by Tim Birkhead
Who’d be a bird anyway? Chickens have bi-focal vision: one eye for the close-up work of pecking seed; one for the fox on the horizon or the hawk in the sky. Peregrine falcons don’t swoop directly on prey – as the crow flies, to coin a phrase – but in a wide arc, using the […]
Scientists identify 137 protected areas most important for preserving biodiversity
Want to save the world’s biodiversity from mass extinction? Then make certain to safeguard the 74 sites identified today in a new study in Science. Evaluating 173,000 terrestrial protected areas, scientists pulled out the most important ones for global biodiversity based on the number of threatened mammals, birds, and amphibians found in the parks. In […]
The evolution of cooperation: communal nests are best for ruffed lemurs
Raising young lemurs in communal crèches benefits both mothers and offspring, a new study has found. Andrea Baden and colleagues, of Yale University, studied a group of black-and-white ruffed lemurs (Varecia variegata) in Ranomafana National Park, Madagascar. This is the first study to examine the consequences of different parenting strategies in the ruffed lemur. By […]
World’s rarest duck’s best friend: a pair of socks!
A critically endangered duck is being rescued from extinction by British and Malagasy conservationists with the help of a pair of socks. The Madagascar pochard was thought to be extinct until 2006, when a pocket of just 22 survivors was discovered at a single remote lake in northern Madagascar. The Wildfowl & Wetlands Trust and […]
Does size matter (for lemur smarts, that is)?
Does size matter? When referring to primate brain size and its relation to social intelligence, scientists at Duke University do not think the answer is a simple yes or no. In the past, scientists have correlated large brain size to large group size. However, in a new study published in PLoS ONE, scientists at Duke […]
Population of newly discovered lemur in Madagascar down to last 50 individuals (photo)
Researchers have discovered a new — and critically endangered — species of lemur on the island of Madagascar. The primate is formally described in the journal Molecular Phylogenetics and Evolution. The Lavasoa Dwarf Lemur (Cheirogaleus lavasoensis) inhabits three isolated forest fragments in the Lavasoa Mountains in southern Madagascar. Like other dwarf lemurs, the species is […]
