Wolves are vertebrates because:

  1. they are warm-blooded
  2. they have fur
  3. they have four legs
  4. they have a cranium that protects the brain
  5. none of the above

 

What was the focus of the study?

  1. increasing beaver population due to wolf reintroduction
  2. how wolves influence the diversity of ecosystems
  3. how wolves impact songbird dynamics
  4. how wolves affect micro content of soil
  5. sapling survival of willow trees

 

What was the ecosystem response to wolf extirpation at Yellowstone?

  1. significant increase in elk, in response to lack of predation
  2. decrease in ecosystem diversity
  3. decrease in beaver populations
  4. all of the above
  5. none of the above

 

What was the ecosystem response to wolf reintroduction at Yellowstone?

  1. increase in beaver colonies
  2. taller trees and plants
  3. decrease in elk
  4. overall, major increase in ecosystem diversity
  5. all of the above

 

Wolves are a keystone species at Yellowstone because:

  1. the ecosystem collapses without them
  2. they are a top predator
  3. they affect beaver populations
  4. they aren’t a keystone species
  5. they affect trees
