It doesn’t take much for a predator to terrify their prey. No tricks. No treats. Just good old-fashioned fear of being eaten. A predator could just be exploring and wandering around — perhaps not even ...

A new study reports on the diverse ways that aquatic predators, such as sharks and alligators, can impact ecosystems and also benefit human society. The study shows how these important ecological ...

A Colorado State University experiment spanning more than two decades has found that removal of apex predators from an ecosystem can create lasting changes that are not reversed after they return—at ...

Restoration of wolves to Yellowstone National Park has allowed vegetation to recover from over-browsing by elk (left photo taken in 1997, right in 2001). Photos courtesy of W. Ripple. The decline of ...

Biological diversity, or "biodiversity," refers to variability found at all levels of biology. Biodiversity is commonly broken down into three levels or types: genetic diversity, species diversity, ...

The susceptibility of ecosystems to disruption depends on a lot of factors that can't all be grasped. A new method provides good results with only limited information about the properties of predators ...

An important goal in ecology is developing general theory on how the species composition of ecosystems is related to ecosystem properties and functions. Progress on this front is limited partly ...
