Winter Sleep, A

Synopsis: There is more to hibernation than just ‘sleeping off the winter’. Observations of the Canadian ground squirrel have shown that the animal can control its sleep, even at body temperatures close to freezing. Dr Keraig Heller of Stanford University explains how hibernation might have evolved.

At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
