How is hibornation different fron estivation?

Hibernation and estivation are both forms of dormancy but occur in different environmental conditions. Hibernation is a state of reduced metabolic activity that many animals enter during cold winter months to conserve energy when food is scarce. In contrast, estivation is a similar state that animals enter during extremely hot and dry conditions, allowing them to avoid desiccation and conserve resources. Both strategies help organisms survive adverse environmental conditions, but they are triggered by different seasonal changes.
