These direct and indirect effects of starfish, sea otters, and other so-called keystone species describe a phenomenon known as a trophic cascade.

A trophic cascade occurs when predators limit the density and/or behavior of their prey and thereby enhance the survival of the next lower trophic level. I explain to my students that it is like a domino effect- once one part of the food web gets disrupted, everyone else ...What the authors describe is called a “trophic cascade” in which higher-order consumers significantly affect how organisms interact at three or more lower trophic levels of the food web. The Casini et al. study illustrates and reaffirms three important points: ( i) Apex predators can affect large pelagic marine ecosystems.Trophic cascades in ecological communities are defined as the propagation of indirect effects between nonadjacent trophic levels in a food chain or food web. Typically, cascades are driven by predation from the top-down, with altered herbivore densities mediating the ultimate effects on the biomass of primary producers. ...

There have been several attempts to come up with a proper definition for the term trophic cascade and its theory. Still, it refers to 'the interaction of different intermediary species via an indirect manner, spreading downward in a top-down forcing through food web that originated with predators.'question seems so simple, yet the answer has been exasperatingly elusive. But in the answer lies the key to how nature works, so the answer matters enormously, both as a matter of scientific understanding and as a point of departure for how to ensure the survival of biodiversity on earth.A key concern with the impacts of overfishing is not exclusive to the methods of extraction. The loss of keystone species can result in potential disruption to trophic structures and alter benthic diversity. Studies variously link the loss of predators (Ruppert et al., 2013) and herbivores (Hughes, 1994) to observable shifts in reef systems.Exploring Trophic Cascades: HHMI Click and Learn Go to the website: - trophic-cascades 1.
