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

lower their body temperature, becoming inactive for days at a time. Dwarf lemurs are no exception.

"To the casual observer, it looks for all the world as if the animals are dead. Their bodies are cold, they are utterly still and they take a breath only once every several minutes or so," said co-author Anne Yoder, director of the Duke Lemur Center.

Western dwarf lemurs hibernate in drafty tree holes, where their body temperature fluctuates by as much as 20 degrees with the outside air. But the researchers found that eastern dwarf lemurs keep their body temperatures more constant in cozy underground burrows.

The research suggests that lemur hibernation -- and therefore primate hibernation -- may not be so different after all. "Maybe these lemurs, though they live in the tropics, look more like temperate hibernators than we thought," Blanco said.
