The article offers information on hibernating animals, such as bears and bats, chipmunks and woodchucks. True hibernation is considered to be different than sleeping. It is a state in which the body changes dramatically, with a significant slowing down of the whole metabolism. Scientists debate whether these animals are really hybernating, or just sleeping a lot during cold weather.

The hibernation rituals of mammals such as squirrels are mentioned. The amount of energy which possums use while...

    Hibernation is the sleep-like state that some animals go in during the winter months. Animals hibernate to protect themselves against the cold and to reduce their need for food. In cold weather, animals lose body heat more quickly than in warmer weather. In preparation for hibernation, the...

    Currently, it is believed that toad oocyte maturation is dependent on the physiological conditions of winter hibernation. Previous antibody-blocking experiments have demonstrated that toad ubiquitin carboxyl-terminal hydrolase L1 (tUCHL1) is necessary for germinal vesicle breakdown during toad...
