Putting Together the Pieces to Prevent Tiger Extinction

Two hundred years ago, over 60,000 tigers lived in India. This figure has since decreased by 90 percent. Today, fewer than 3,500 tigers remain in the wild, and only seven percent of the historic tiger habitat remains. These habitats, mostly scattered across India, are becoming increasingly isolated as the country continues to urbanize. Dr. Uma Ramakrishnan, a population geneticist and biodiversity ecologist at India's National Centre for Biological Sciences, uses genetic information from tigers and landscape modeling of India to help curtail this disturbing trend.
