Sean Carroll and Bob Paine on a film shoot in January 2016.
We are sad to report that Bob Paine, pioneering ecologist who coined the terms "keystone species" and "trophic cascade," passed away on June 13, 2016.
We are very grateful to have had the opportunity to work with Bob on a film about his work. A terrific person and mentor, he will be missed by many.
