The predominant trend had been that people thought that fish have a powerful effect on their environment, and they drive the changes in everything else. What we've seen is the reverse, that fish are responding to a change in their habitat. We think that a lot of fish communities are fundamentally changed by fishing. Our study is really nice in that we are working on populations that have never been fished, so their population dynamics can be seen being driven by natural processes.
