why do some organisms hibernate in deserts?
Answers
Answer:
It is actually called Asteivation.
The reason is same as that of hibernation, for conserving energy.
Winter is a time of magic in the animal world. Species as diverse as bears and beetles disappear from the landscape, with hibernation on their minds. Most do not travel far. They venture into caves and dens, descend from mountains, burrow deep underground, or simply dig under rocks or logs. During this self-imposed exodus, they may rely on extra fat or cached food. Some curl up alone. Others group together for warmth. The winter adaptations – practiced by reptiles, invertebrates, amphibians, mammals and birds – can be likened to Ponce de Leon’s Fountain of Youth. Hibernation helps animals cheat winter’s potential death grip and prolong their lives.
Although it is often viewed as a phenomenon of colder climates, hibernation also occurs in the desert. A classic hibernator is the desert tortoise, which heads underground into burrows with the onset of cold. In a suspended state, it drastically reduces its metabolic rate, digestion, urination and defecation. Although some move only slightly during winter, others may take advantage of warm days and head out to bask in the sun. Hibernation can last from October to March.
