Exercise 12

Communities in different areas may be organized in different ways. For instance, C. Ralph (1985) found that in Patagonia in Argentina, as foliage height diversity increases, bird species diversity decreases. This result is exactly the opposite of the pattern observed by MacArthur (1958) and others reviewed in chapter 16. Design a study aimed at determining the environmental factors determining variation in bird species diversity across Ralph's Patagonian study sites.
