Local mountain lions, which typically steer clear of human-populated areas, took notice, expanding their ranges closer to urban areas, the study found.

The Scientist spoke with study author Chris Wilmers, a wildlife ecologist at the University of California, Santa Cruz, about this work, and what the findings suggest about how ecosystem dynamics can shift in the face of widespread changes in human behavior.
