प्रश्न
Write the inference drawn by Alexander von Humboldt after his extensive explorations of South American jungle.
उत्तर
Alexander von Humboldt observed that within a region species richness increased with increasing explored area, but only up to a limit. In fact, the relation between species richness and area for a wide variety of taxa (angiosperm plants, birds, bats, freshwater fishes) turns out to be a rectangular hyperbola.
