A critique from a team led by Utah State University ecologist Dan MacNulty and published in Forest Ecology and Management has prompted a formal correction to a high-profile study on aspen recovery ...

Over the last three decades, Yellowstone National Park has undergone an ecological cascade. As elk numbers fell, aspen and willow trees thrived. This, in turn, allowed beaver numbers to increase, ...

The commonly held claim that wolves reintroduced into Yellowstone National Park in the mid-1990s spearheaded a "trophic cascade" of ecological restoration, as some studies indicated, is unfounded, ...
