Question

Species area relationship curve had been proposed by

• B. Edward Wilson
• C. Paul Ehlrich
• D. Von Humboldt.

Answer 1

Answer: (D)

Von Humboldt.

Answer 2

German naturalist and geographer Alexander von Humboldt while exploring the wilderness of South American jungles found that within a region the species richness increased with increasing area but upto a certain limit. On this basis, he proposed species area relationship curve. The relationship between species richness and area turned out to be rectangular hyperbola for a wide variety of taxa whether they are birds, bats, freshwater fish or flowering plants. On a logarithmic scale, it is a straight line. log S = log C + Z log A Here S is species richness, Z is slope of line or regression coefficient, C is Y intercept and A is area.
