Summary

Providence, Rhode Island—In a puzzle dating back to the time of Darwin, ecologists have wondered about diversity's effect on an ecosystem's health. Does it make ecosystems more productive and stable, as some think, or are less diverse ecosystems better off? Recently, however, results produced both in field studies and in mathematical models have been tilting the balance toward the former view. The findings have implications for the management of forests, grazing lands, and other ecosystems.
