THE TROPHIC CASCADE HYPOTHESIS In 1979, Paine combined his own results with those of others, including Estes and Palmisano, to propose the idea of trophic cascades, in which direct and indirect effects from a species at or near the top of the food chain propagate down and regulate the species and population sizes in the rest of the community.3.

Trophic cascades occur when predators reduce the abundance or change the activity of their prey, thereby allowing species in the next trophic level to increase in number. These indirect effects by the predator can trickle down (or cascade) to many lower levels of the food chain.
