Questions

Community Ecology

1. De?ne competition, exploitative interactions, mutualism, amensalism and cominensalism.

2. Explain the relationship between competitive exclusion and realized and fundamental niches.

3. How do resource partitioning and character displacement a?'ect competitive interactions. Does either one of these response to competition involve a populationfgenetic change? What evidence would you need to observe to determine if populations are evolving in response to competition (rather than simply changing their behavior or phenotype)?

4. Compare the lethality and intimacy of parasites, parasitoids, grazers, and predators Twith respect to their prey/hosts.

5. List the main types of predator and herbivore escape mentioned

6. Describe Mullerian and Batesian mimicry. When would you expect to see each type of mimicry evolve?

7. What is me difference between an obligate and a facultative mutualism?

8. How might "cheating" affect a mutualistic relationship between species?

9. Explain how indirect interactions and multi-trophic interactions can in?uence species in a community.

10. List and describe the three main types of food webs (connectedness, energy flow, and functional).

11. Compare top down and bottem up regulation of community diversity

12. Distinguish between keystone and dominant (foundation) species and explain how they can affect food webs and diversity.

13. De?ne and outline the various succession concepts: primary vs secondary succession, allogenic vs autogenic succession, and monoclimax vs polyclimax vs climax pattern.

14. Explain the relationship between species richness, species evenness, and species diversity.

15. Describe what is meant by alpha, beta, and gamma, diversity.

16. How and why do habitat heterogeneity, geographic area, disturbance, and latitudinal gradients lead to differences in species diversity.
