Animal Adaptations in a Changing Climate

The video explores how animals are adapting to climate change through three case studies: lizards in the Caribbean adapting to stronger hurricanes, Humboldt squid in the Gulf of California responding to marine heat waves, and dove keys in the Arctic adjusting their feeding patterns due to retreating ice flows. These adaptations highlight the concept of plasticity and natural selection in real-time, emphasizing the urgency of understanding which species can adapt and which are at risk. The video concludes by suggesting that human behavior can also change in response to climate change.

What is one of the unexpected effects of climate change on animals?

• Animals are migrating to colder regions.

• Animals are evolving at a slower pace.

• Animals are changing faster than anticipated.

• Animals are unaffected by climate change.

What physical trait helped Anole lizards survive hurricanes?

• Smaller front legs

• Larger toe pads

• Thicker skin

• Longer back legs

How did Colin Donahue test the lizards' ability to withstand hurricane-force winds?

• By using a wind tunnel

• By observing them during a real hurricane

• By simulating a hurricane in a lab

• By aiming a leaf blower at them

What change was observed in the Humboldt squid due to marine heat waves?

• They grew larger in size.

• They reduced in size by 50% or more.

• They migrated to colder waters.

• They stopped reproducing.

What is plasticity in the context of animal adaptation?

• The ability to adapt behaviorally or physically to environmental changes

• The ability to change color

• The ability to reproduce rapidly

• The ability to migrate long distances

How did the little auk adapt to the retreating ice flows?

• By increasing their flight speed

• By hibernating during the winter

• By finding a new food source closer to their breeding grounds

• By migrating to warmer regions

What was the new feeding strategy of the little auk?

• Feeding at the mouth of the fjord where meltwater meets ocean currents

• Feeding on fish instead of plankton

• Feeding on land instead of in the water

• Feeding during the night instead of the day

What is the significance of studying animal adaptations to climate change?

• To predict future weather patterns

• To identify which species are more resilient and allocate resources accordingly

• To develop new technologies for human use

• To find new species for scientific research

Which species was the first confirmed mammal casualty of climate change?

• The polar bear

• The little auk

• The bramble key melomys

• The Humboldt squid

What lesson can humans learn from animal adaptations to climate change?

• To ignore climate change as it only affects animals

• To change behaviors contributing to climate change

• To relocate to different regions

• To focus solely on technological solutions
