How did David Tillman show that the “Stability of a community depends on its species richness”? Explain.
The stability of a community depends on its species richness. David Tilman’s long-term ecosystem experiments using outdoor plots provided the answer for species richness. Tilman found that plots with more species showed less year-to-year variations in total biomass. He also showed that increased diversity contributed to higher productivity. Thus he established that the stability of a community depends on its species richness.
