When you don’t know if you have much of a future, you focus more on the now—there’s no point in biding your time and waiting when you could die any day.

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.
