Study Notes
Hibernation
- Hibernation is a deep sleep animals enter during harsh winter weather, helping them survive lacking food and extreme cold.
- Animals prepare for hibernation by eating large amounts of food in the fall to gain weight and energy reserves.
- Their metabolisms slow down to conserve energy.
- Hibernation is crucial for survival in environments where food becomes scarce in winter and temperatures plummet.
- Many plants stop producing food sources, and prey animals may also hibernate, reducing food availability.
- Animals with thin fur or no ability to warm up risk freezing without hibernation.
Importance of Hibernation
- Hibernation allows animals to avoid the constant struggle for food and cold weather survival.
- Animals find safe shelters to sleep during winter.
- Animals' bodies enter a state where they conserve energy by slowing heart rate and lowering body temperature.
Animals During Hibernation
- Hibernating animals include bears, ground squirrels, groundhogs, hedgehogs, rodents, mice, raccoons, bats, wood frogs, woodchucks, turtles, and some insects.
- Animals have an instinctive response and prepare for hibernation by eating a lot of food before winter.
- Bears, for instance, can gain significant weight—up to 30 pounds per week.
- Animals' bodies regulate by slowing heart rate, breathing, and dropping body temperature during hibernation.
- Woodchucks' heart rate and breathing decrease dramatically during hibernation.
- Hibernation involves lowering body temperature to near freezing to further decrease energy use.
- Animals like woodchucks may briefly wake to shiver and raise their body temperature when it drops too low.
- Hibernation ends when spring arrives, and the weather warms.
- Examples of how each animal can be impacted vary. Bears have slower heart rates. Ground squirrels have slower heart rates.
