Therefore, we propose the following definition (see Box 2 for related terms): ' Trophic cascades are indirect species interactions that originate with predators and spread downward through food webs'. This definition is consistent with Paine's original conception of nested sets of species interactions [5].We conclude that trophic cascades and top-down community regulation as envisioned by trophic-level theories are relatively uncommon in nature.
