Researchers challenge Hibernation concepts



 Science Daily reports that Researchers from Tel Aviv University, have new research that will change the standard concepts of hibernation. Hibernation is thought to occur only in colder temperatures to allow some mammalian species to experience a period of dormancy and undergo physiological changes such as lower heart rates and body temperature. This allows the animal to conserve energy and be able to survive cold winters. 

The Middle East experiences temperate winters and has been thought to be an unlikely environment for hibernation. Researchers have discovered two species of the mouse-tailed bat (Rhinopoma microphyllum and R. Cystops) hibernating at constant temperatures of 68⁰ F, which is considered unusually warm. The bats were found to be semi-conscious and breathing once every 15-30 minutes.

This research shows that animals do not need to lower their body temperatures in order to lower their energy expenditures.
