Make like a tree

Charlie Heck introduces a video discussing how different tree species in southwestern Colorado adapt to drought conditions. The University of Washington researchers studied the ponderosa pine and trembling aspen, revealing their distinct survival strategies. The ponderosa pine conserves water by closing leaf openings, while the aspen continues to grow, risking vulnerability to prolonged droughts. These adaptations may reshape forest ecosystems, and researchers aim to identify vulnerable tree life stages. The video concludes with a humorous exchange about weather metaphors.

What is the main analogy used to describe how different tree species handle drought conditions?

• Comparing trees to fish in a pond

• Comparing trees to animals in the wild

• Comparing trees to machines in a factory

• Comparing trees to people handling bad weather

Which tree species uses a strategy of drought avoidance by conserving water?

• Maple Tree

• Trembling Aspen

• Oak Tree

• Ponderosa Pine

How does the Trembling Aspen respond to drought conditions?

• It stops growing completely

• It continues to grow with no change in water conservation

• It increases its water conservation

• It sheds its leaves

What might be a consequence of the Trembling Aspen's drought strategy?

• Its range may expand

• It may become more vulnerable to prolonged drought

• It becomes more resilient to drought

• It will grow faster

What do researchers aim to identify regarding tree life stages?

• The stages that are most resistant to pests

• The stages that produce the most oxygen

• The stages that grow the fastest

• The stages most vulnerable to drought
