Primate hibernation more common than previously thought
Date:5/2/2013

DURHAM, N.C. -- Until recently, the only primate known to hibernate as a survival strategy was a creature called the western fat-tailed dwarf lemur, a tropical tree-dweller from the African island of Madagascar.

But it turns out this hibernating lemur isn't alone. In a study appearing May 2 in the journal Scientific Reports, researchers report that two other little-known lemurs -- Crossley's dwarf lemur and Sibree's dwarf lemur -- burrow into the soft, spongy rainforest floor in the eastern part of Madagascar, curl up and spend the next three to seven months snoozing underground.

By comparing the hibernation habits of eastern dwarf lemurs and their western counterparts, researchers hope to shed light on what sends hibernating animals into standby mode, and whether lemurs -- our closest genetic relatives known to hibernate -- do it differently from other hibernating animals.

"Exactly what triggers hibernation is still an open question," said lead author Marina Blanco a postdoctoral researcher at the Duke Lemur Center.

Unlike animals such as bears and ground squirrels, which hibernate to survive the cold, western dwarf lemurs hibernate to survive during western Madagascar's long dry season -- a time when temperatures top 85 degrees, trees drop their leaves and food and water are in short supply.

But the hibernation habits of Madagascar's eastern dwarf lemurs, whose homes include high-altitude forests where winter temperatures occasionally dip below freezing, were poorly known.

"It's a very different environment," Blanco said.

To find out more, Blanco and her colleagues trapped and fitted the squirrel-sized animals with temperature-sensitive radio collars before the start of the hibernation season, allowing them to find the lemurs' underground burrows and monitor their body temperature once hibernation began.
