|
Explain species richness, diversity index and rank-abundance diagrams and compare what each measures.
|
TBD
|
|
|
What is the paradox of enrichment, and how can the paradox be resolved?
|
TBD
|
|
|
Explain, with examples, the contrasting effects that predation can have on species richness.
|
TBD
|
|
|
Researchers have reported a variety of hump-shaped patterns in species richness, with peaks of richness occurring at intermediate levels of productivity, predation pressure, disturbance and depth in the ocean. Review the evidence and consider whether these patterns have any underlying mechanisms in common.
|
TBD
|
|
|
Why is it so difficult to identify 'harsh' environments?
|
TBD
|
|
|
Explain the intermediate disturbance hypothesis.
|
TBD
|
|
|
Islands need not be islands of land in an ocean of water. Compile a list of other types of habitat islands over as wide a rnage of spatial scales as possible.
|
TBD
|
|
|
An experiment was carried out to try to separate the effects if habitat diversity and area on arthropod species richness on some small mangrove islands in the Bay of Florida. (See problem, page 356 in text)
|
TBD
|
|
|
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?
|
TBD
|
|
|
Describe how theories of species richness that have been derived on ecological time scales can also be applied to paterns observed in the fossil record.
|
TBD
