Examines those animals that cannot migrate and are forced to remain in a habitat that is inhospitable, and consequently sleep deeply for weeks or months. This unique trait, known as hibernation for winter sleep and estivation for its summer equivalent, involves many special behaviours - how do such animals prepare for sleep? Where do they sleep? How do they store energy? How do they wake up? The book provides a thorough guide, perfect for understanding the behaviour and biodiversity of a fascinating and unusual group of animals. "Hibernation" provides thorough coverage of the animals that have this unusual behaviour, including: mammals of the temperate zones, that can raise their temperature when in danger of freezing; cold-blooded fish, amphibians, and reptiles that have no control over their body temperature, and therefore cannot raise it to avoid being frozen; northern bears, the only animals to raise their young while hibernating; and the animals that live in semi-arid regions which encase themselves in a waterproof membrane to avoid drying out.
"This title has been reviewed jointly with Nocturnal Animals and Hibernation, both by Clive Roots.....These three titles fill a niche. Most available books on flightless birds, nocturnal animals, and hibernation are for a juvenile audience, or they focus narrowly on particular animals (e.g., penguins) rather than giving a broad overview. Undergraduates in zoology will find these books useful. Recommended. Lower-/upper-level undergraduates, two-year technical program students, and general readers." -
