Refer to figure 22.5 , which MacArthur and Wilson (1963) used to show how isolation affects species richness on islands. Find a detailed map of the Pacific Ocean and locate New Guinea. Next locate as many of the "near," "intermediate," and "far" islands on the map as you can. This will give you a better sense of the distances represented by the islands. How do the numbers of species on near, intermediate, and far islands support the hypothesis that island isolation tends to reduce species richness
