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'. |
