Problem 1
Explain species richness, diversity index and rank-abundance diagrams and compare what each measures.
Problem 2
What is the paradox of enrichment, and how can the paradox be resolved?
Problem 3
Explain, with examples, the contrasting effects that predation can have on species richness.
Problem 6
Explain the intermediate disturbance hypothesis.
Problem 9
A cascade effect is sometimes proposed to explain the increase in species richness during a community succession. How might a similar cascade concept apply to the commonly observed gradient of species richness with latitude?
Problem 10
Describe how theories of species richness that have been derived on ecological time scales can also be applied to patterns observed in the fossil record.
