According to Alexander von Humboldt
Options
- ASpecies richness increases with increasing area,but only up to limit
- BThere is no relationship between species richness and area explored
- CSpecies richness goes on increasing with increasing area of exploration
- DSpecies richness decreases with increasing area of exploration
Correct answer
A. Species richness increases with increasing area,but only up to limit
Step-by-step solution
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 (Figure 15.2).
