Chapter 58, Problem 3TY

Which evidence suggests that more diverse communities are more stable than less diverse communities?

  1. a. Agricultural land, with fewer species, undergoes less frequent pest outbreaks than natural prairies containing more species.
  2. b. In Australia, introduced rabbits frequently assume pest proportions. In Europe, coevolved predators such as foxes prevent rabbit populations from reaching pest proportions.
  3. c. Long-term studies of American grasslands show fields with high numbers of plant species vary less in biomass from year to year.
  4. d. Both a and b are correct.
  5. e. Both b and c are correct.

Communities with fewer feeding relationships are less resilient to change. d. Native ants have a higher relative abundance compared to the invasive red ant.
