Identify the ecologist from the given hints. 
(i) He carried out long-term ecosystem experiments using outdoor plots.
(ii) In his experiments, he showed that increased diversity contributed to higher productivity.

A

Ahmed Khan

B

David Tilman

C

Stanley Cohen

D

Earnest Chain

E

Herbert Boyer

Answer

George David Tilman is an American ecologist. It is said that a stable community should not show too much variation in productivity from year to year; it must be either resistant or resilient to occasional disturbances (natural or man-made), and it must also be resistant to invasions by alien species. David Tilman’s long term ecosystem experiments using outdoor plots show how these attributes are linked to species richness in a community. Tilman found that plots with more species showed less year-to-year variation in total biomass. He also showed that in his experiments, increased diversity contributed to higher productivity. 
So, the correct answer is 'David Tilman'.
