Trophic cascade | Definition, Importance, Examples | Britannica Trophic cascade, an ecological phenomenon triggered by the addition or removal of top predators and involving reciprocal changes in the relative populations of predator and prey through a food chain A trophic cascade often results in dramatic changes in ecosystem structure and nutrient cycling
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
What is a Trophic Cascade? - Oregon State University We propose that trophic cascades specify the effects of predators that propagate downward thorough food webs across multiple trophic levels Trophic cascades can be triggered by consumptiveinteractionsbetweenpre-dators and prey and nonconsumptive effects due to perceived predation risk by prey
19. 3: Trophic Cascades - Biology LibreTexts Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when a trophic level in a food web is suppressed
What is Trophic Cascade? Various Types, Effects and Examples A trophic cascade is a side-effect when a trophic level (species) of the ecosystem is reduced or removed This triggers a cascade (series of events effects on other species) that changes the balance of the entire ecosystem
Trophic Cascades Across Diverse Plant Ecosystems When the impact of a predator on its prey's ecology trickles down one more feeding level to affect the density and or behavior of the prey's prey, ecologists term this interaction a feeding, or
Trophic Cascades: How One Species Can Reshape an Ecosystem Trophic cascades refer to the ecological process where changes in the population or behaviour of one species, often a top predator, cause a series of changes at lower levels in the food web This can lead to significant alterations in the abundance and diversity of species throughout the ecosystem
What Is a Trophic Cascade: Key Examples A trophic cascade occurs when changes in one species trigger a series of effects throughout an ecosystem This phenomenon highlights the importance of strongly influencing predator-prey relationships
