Natural Cycles: Hibernation and Estivation

The video explains how animals like salamanders and frogs hibernate in cold climates, using adaptations such as antifreeze-like substances in their tissues to survive freezing temperatures. It also discusses how some plants, particularly in hot and dry climates like California, enter a state of dormancy called aestivation during the summer, appearing dead but reviving with rainfall in cooler seasons.

What is the term used for the resting state that some living things enter during hot and dry summers?
