Chapter 45 (part 2): Community Ecology

  1. Know the difference between the four types of species interactions: competition, consumption, mutualism, commensalism. Give examples of each.
  2. What is the difference between intraspecific and interspecific competition.
  3. What happens to intraspecific competition as the population density increases?
  4. What is the niche model of speciation.
  5. What is the competitive exclusion principle.
  6. What is the difference between asymmetric and symmetric competition?
  7. What is the difference between a fundamental and a realized niche?
  8. The niche differentiation hypothesis suggests that natural selection favors what?
  9. List three types of consumption.
  10. What are some defenses against consumption?
  11. What is the purpose of mimicry?
  12. What in the world is pseudocopulation mimicry?
  13. Be able to explain the coevolutionary arms race. What traits do predators tend to evolve? What traits do prey tend to evolve?
  14. What is the difference between top-down vs. bottom-up hypothesis of herbirvore control?
  15. What are some examples of mutualisms?
  16. What is an ecological disturbance?
  17. What is a disturbance regime?
  18. What factors affect a disturbance regime?
  19. What is ecological succession?
  20. What is difference between primary and secondary succession?
  21. What do early successional communities composed of?
  22. What characteristics do r-selected species share? What adaptations do r-selected species have?
  23. What characteristics to K-selected species share? What adaptations to K-selected species have?
  24. What is a climax community?
  25. What did Clements hypothesize about climax communities?
  26. What predictions do the theory of island biogeography propose?
