Trophic cascades are powerful indirect interactions that can control entire ecosystems. Trophic cascades occur when predators limit the density and/or behavior of their prey and thereby enhance ...

Wolves culled the elk. Fewer elk means more aspens can grow. More beavers are attracted to the trees. It's called a trophic ...

This type of change is the result of a really cool phenomenon known as a trophic cascade. It’s an indirect effect predators have that extends downwards through the food web. In this context ...

The release of gray wolves in Yellowstone decades ago still stands as one of the few examples of a predator reintroduction, and the lessons learned continue to be debated. New projects aim to do it ...

Three decades after their reintroduction, Yellowstone’s wolves have transformed the park. What’s next for the ecosystem and ...

British Columbia was a classic example of the domino effect, which ecologists call a trophic cascade, that comes with reintroducing a keystone species: otters eat urchins, so kelp can regrow.

We have shown for instance, that in clay-turbid conditions, top-down regulation may not work in a manner predicted by the trophic cascade hypothesis. This is because turbidity has differential effects ...

Trophic cascades are powerful indirect interactions that can control entire ecosystems. Trophic cascades occur when predators limit the density and/or behavior of their prey and thereby enhance ...

As some conservationists and researchers begin to return large carnivores to areas where they once roamed, scientists intensify efforts to study the ecological roles of predators. On March 7, ...
