Summary

Two new population genetics studies provide sobering news for efforts to protect endangered species. The minimum number of individuals needed to provide a genetically robust population capable of long-term survival may be as high as 10,000. Previous estimates had put the figure at 500, and many endangered species are down to just a few dozen individuals.
