Question 4 Multiple Choice (Single Answer)

Which of the following is NOT a consequence of the species-area relationship?

  1. Larger islands have more species than smaller islands
  2. Smaller islands have higher extinction rates than larger islands
  3. Island species are more likely to be endemic than mainland species
  4. Island species are more likely to be generalists than mainland species
Question 5 Multiple Choice (Single Answer)

The equilibrium theory of island biogeography predicts that:

  1. The number of species on an island will increase over time
  2. The number of species on an island will decrease over time
  3. The number of species on an island will remain constant over time
  4. The number of species on an island will fluctuate over time
Question 6 Multiple Choice (Single Answer)

Which of the following is NOT a conservation implication of the species-area relationship?

  1. Larger islands should be prioritized for conservation
  2. Habitat corridors should be created to connect fragmented habitats
  3. Invasive species should be controlled to prevent extinctions
  4. Climate change should be mitigated to reduce the impacts on island ecosystems
Question 7 Multiple Choice (Single Answer)

Which of the following is NOT a factor that affects the rate of species extinction on an island?

  1. Island size
  2. Distance from the mainland
  3. Habitat diversity

Question 8 Multiple Choice (Single Answer)

The species-area relationship can be expressed mathematically as:

  1. $$S = cA^z$$
  2. $$S = cA^{1/2}$$
  3. $$S = cA^{1/4}$$
  4. $$S = cA^{3/4}$$
