Mountain lions living in Greater Los Angeles could be at risk of extinction within the next 50 years if the population remains isolated by freeways and other forms of human development, UCLA and National Park Service wildlife ecologists are warning.

About 15 pumas survive in the Santa Monica Mountains, cut off from the rest of their species by a host of man-made obstructions.
