Abstract
Trophic cascades are the time-honored focal point of food-web dynamics. The y are the best loved example of indirect effects in undergraduate ecology t extbooks and they represent a potentially useful application of theory. Res earchers have found them from the Arctic to the tropics. But, can we agree on what they are? Here, we seek to clarify the terminology of trophic casca des and call for a consensus on how to quantify cascading effects in the fu ture.
