You Are Studying a Type of Tree That Grows in Dense

question 72

Essay

You are studying a type of tree that grows in dense groups made up of many individuals. These groups are generally separated by quite some distance, so each group is relatively isolated from the others. What are three possible factors that might cause this patchy distribution, and what kinds of data would you collect to determine the factor that is responsible for the dispersion you observe?
