Question

1) What are the differences between interdependent community and the independent community perspectives of Frederic Clements and Henry Gleason? (Ch. 18)

2) Given that the distributions of many animals are determined by the species composition of the plant community, what might you predict about the diversity of animals in an ecotone? (Ch. 18)

3) How did Robert Whittaker’s data on plant species composition along gradients of temperature and moisture in mountains provide evidence against the idea of interdependent communities? (Ch. 18)

4) Explain why ecologists use both species richness and species evenness when they quantify species diversity. (Ch. 18)

5) Why does and increase in total resources or number of added resources commonly lead to declines in species diversity? (Ch. 18)

6) What does it mean when a community is said to exhibit top-down control vs. bottom-up control? (Ch. 18)

Explanation / Answer

1). The species of interdependent community does not interact with the surrounding communities, but there is interaction between the independent communities and neighbouring communities. In case of species belonging to the interdependent communities, they depend on one another for survival, but this is not true for independent communities.
