Ecology and the environment

Answer the following in your own words:
1) Describe the equal chance hypothesis in your own words (2 pts)
2) Explain why, according to the intermediate disturbance hypothesis, diversity declines when disturbance occurs too frequently or not frequently enough (2 pts)
3) Describe the methods presented for testing the niche-diversification hypothesis, and the potential limitations (2 pts).
4) Is it possible that more than one hypothesis is correct? Why? (2 pts)
5) Describe how the intermediate hypothesis applies to coral reefs and tropical forests. (2 pts).
6) What are other hypotheses for why there is greater diversity in tropical rainforests and coral reefs? (2 pts)
7) Explain the importance of the “edges” of disturbance. How do the species on the edges contribute to recovery from a disturbance? (2 pts)
8) Do you think Connell’s hypotheses apply to less diverse ecosystems such as the Arctic or deep ocean? Explain. (2 pts)
9) Which of these hypotheses, if any, can be applied to motile (non-sessile) organisms? How would the ability to move affect the overall diversity? (2 pts).
10) Write out the citation for this journal article using the format of the journal Ecology (2 pts).
