Trofische Cascade

Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when a trophic level in a food web is suppressed. For example, a top-down cascade will occur if predators are effective enough in predation to reduce the abundance, or alter the behavior, of their prey , thereby releasing the next lower trophic level from predation (or herbivory if the intermediate trophic level is a herbivore).
