Hibernation and Climate Change Effects

The video explores hibernation, a state of reduced metabolic activity used by animals to survive harsh winters. It discusses the evolutionary history of hibernation, adaptations animals make to endure winter, and specific hibernation behaviors of various species. The video also covers estivation, a similar process for hot climates, and torpor, a short-term energy conservation state. Finally, it examines how climate change affects hibernation patterns and animal survival.

What is the primary purpose of hibernation in mammals?

• To find more food

• To increase metabolic activity

• To migrate to warmer areas

• To survive harsh winter conditions

Which of the following animals is not a true hibernator?

• Bats

• Hedgehogs

• Bears

• Marmots

How do smaller animals typically prepare for hibernation?

• By staying active throughout winter

• By increasing their body temperature

• By stockpiling food

• By migrating to warmer areas

Which bird species is known to hibernate?

• Sparrow

• Common poorwill

• Eagle

• Penguin

What is estivation?

• A process of increased activity

• A process similar to hibernation for escaping heat

• A process of migration

• A process similar to hibernation for escaping cold

What is torpor?

• A long-term hibernation state

• A short-term energy conservation state

• A migration strategy

• A state of increased metabolic activity

How does climate change affect hibernating animals?

• It makes winters colder

• It increases food availability

• It shortens or lengthens hibernation periods

• It has no effect

What happens to hibernators if they emerge prematurely due to climate change?

• They find more food

• They increase their fat reserves

• They may face food shortages

• They migrate to other areas

Which factor serves as a cue for yellow-bellied marmots to emerge from hibernation?

• Presence of predators

• Availability of food

• Temperature of the air

• Length of daylight

What is a potential consequence of warmer winters on the environment?

• Growth of harmful infections

• More hibernating animals

• Delayed blooming of flowers

• Increased food supply
