One of the most fascinating concepts in ecology is the which shows how a single species can physically reshape an entire landscape.
Elk stopped hanging out in open valleys and gorges where they were easy targets.
The classic example is the . It wasn't just about wolves eating elk; it triggered a chain reaction:
