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, ...

A new peer-reviewed study reports that claims of a “world-leading” trophic cascade in Yellowstone National Park are not supported, citing problems with the methods used in earlier research. A newly pu ...

Trait evolution in predator–prey systems can feed back to the dynamics of interacting species as well as cascade to impact the dynamics of indirectly linked species (eco-evolutionary trophic cascades; ...

In Yellowstone National Park — where gray wolves were reintroduced starting in 1995 — researchers have gone back and forth on whether the restoration of wolves has impacted the ecosystem. The idea is ...

Trophic cascades : what they are, how they work, and why they matter / John Terborgh, Robert D. Holt, and James A. Estes -- Food chain dynamics and trophic cascades in intertidal habitats / Robert T.

So the discussion over trophic cascades is understandably nuanced, complex and controversial. “We think it’s more accurate to represent this as a multi-predator, density-mediated trophic cascade,” ...

Bromeliad ecosystems represent unique, naturally occurring microcosms that accumulate water and detritus within their rosettes, providing essential aquatic habitats in tropical forests. These ...
