What is the relationship between species richness and area for different taxa, according to Alexander von Humboldt's observations?
  1. Species richness decreases with increasing area
  2. Species richness remains constant with increasing area
  3. Species richness increases with increasing area, but only up to a limit
  4. Species richness decreases logarithmically with increasing area

Solution

During his explorations in the wilderness of South American jungles, Alexander von Humboldt observed that within a region, species richness increases with increasing explored area, but only up to a limit. The relationship between species richness and area for a wide variety of taxa turns out to be a rectangular hyperbola.
