Trophic cascade - Wikipedia

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).

WebAny action or influence that species have on each other is considered a biological interaction. These interactions between species can be considered in several ways. One such way is to depict interactions in the form of a network, which identifies the members and the patterns that connect them. WebSep 1, 2024 · Facilitation occurs when a tree species ameliorates abiotic stress, caused, for example, by limited nutrient supply, drought, harsh microclimatic conditions, or strong radiation, for a neighbouring tree ( Fig. 1 B). As a result, the performance (e.g. growth and survival) of the facilitated tree species is enhanced when growing in mixture.
