From the story on Wired.com:
An Alaskan bay bitterly contested by fishermen and miners has become the site of a landmark study on population dynamics -- and the findings favor the fish. Published June 2 in Nature, the analysis of Bristol Bay salmon quantifies a common-sense tenet of population dynamics: Diversity produces resilience. Had the proposed Pebble Mine been built in earlier decades, it's possible the bay's sockeye salmon fishery -- the world's largest, worth more than $100 million annually -- might not exist today. "The long-term maintenance of the Bristol Bay sockeye fishery has sometimes been almost totally dependent on the Kvichak watershed," where the mine would be located, said University of Washington biologist Ray Hilborn. "If the entire Kvichak watershed was made nonproductive, then historically, that would have been totally disastrous."
