Removal of predators is often hypothesized to alter community structure through trophic cascades. However, despite recent advances in our understanding of trophic cascades, evidence is often ...

Purpose: To introduce the idea of indirect effects of predator on prey by changing prey behavior, and of trophic cascades - effects of predators on primary producers; to construct a flow diagram of ...

Across North America, mountain lions, bears, and gray wolves have made a remarkable comeback over the last 50 years. Once nearly exterminated, these ...

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 ...

A new analysis challenges one of the most publicized claims about Yellowstone's wolves. In a detailed comment published in Global Ecology and Conservation, researchers from Utah State University and ...

Trophic cascades can determine the structure of aquatic food webs, a role often used to manage water quality in lakes. However, trophic cascades are subject to multiple interacting drivers of ...

It’s an environmental success story that feels like a parable—the reintroduction of wolves in Yellowstone National Park in the mid-1990s triggered a cascade of effects that ultimately restored the ...

If you want a glowing example of how interwoven ecosystem elements are, take a look at Yellowstone National Park. A recent study revealed that even wolves and willow trees depend on one another there.

Purpose: To practice interpreting graphical data; to use the data to address the question of why browsing by elk in Yellowstone was so intense during the 20th century. Why was elk browsing on ...
