Climate Change and Species Adaptation

The video discusses the overwhelming evidence of climate change's damaging effects on the environment, focusing on the increased incidence of weather extremes and their impact on species. It highlights the challenges faced by species like koalas and butterflies in adapting to rapid climate changes, emphasizing the importance of biodiversity and synchronization among species. The video also addresses the critical role of host plants in species survival and the broader implications of global climate change.

What is one of the main concerns about climate change discussed in the first section?

• The melting of polar ice caps

• The increase in average global temperatures

• The rise in sea levels

• The increasing incidence of weather extremes

What is the threshold temperature above which mass extinction events occur for certain species?

• 37 degrees

• 42 degrees

• 32 degrees

• 47 degrees

What is causing species in Canada to shift northward?

• Increased human activity

• Changes in predator populations

• Rapidly warming temperatures

• Decreasing food supply

What is a potential mechanism for range loss at the southern boundaries of species?

• Increasing intensity of extreme weather events

• Decreased predator presence

• Increased food availability

• Improved habitat conditions

Why are koalas struggling to adapt to climate change?

• They have a varied diet

• They can regulate their body temperature easily

• They have limited mobility

• They are highly mobile

How far can a male koala typically travel if leaving its home range?

• 20 kilometers

• 30 kilometers

• 10 kilometers

• 5 kilometers

What is a significant issue for pollinators and flowering plants due to climate change?

• Increased competition for resources

• Increased plant growth

• Mismatch in timing of emergence

• Decreased pollinator populations

What do organisms use to decide when to go into diapause or hibernate?

• Predator presence

• Environmental cues

• Social interactions

• Food availability

What is one of the broader implications of climate change mentioned in the last section?

• Stabilization of weather patterns

• Increased agricultural productivity

• Decreased global temperatures

• Ocean acidification

What is the rate of species loss compared to historical events?

• Unrelated to the age of the dinosaurs

• Slower than the age of the dinosaurs

• Similar to the age of the dinosaurs

• Faster than the age of the dinosaurs
