Predator–prey interactions underpin the structure and function of freshwater and marine communities by regulating population sizes, driving species coexistence and shaping energy flows. Top-down ...

Predators are typically larger, faster, and more powerful than the animals they hunt. Yet in nature, most attacks fail. A new study published in the Proceedings of the National Academy of Sciences, by ...

Researchers used computational simulations to demonstrate how simple sensing and movement rules—such as detection of distance and speed changes—constrain predator–prey interactions. In a simplified ...

The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume?

It doesn’t begin with a fight. It begins with opportunity. A prey animal moves through an area. Tracks appear. Scent lingers just long enough to be noticed. But more than one predator is watching. Not ...

A grey wolf prowls through Yellowstone National Park near Mammoth Hot Springs in Montana. A group of 66 wolves was reintroduced to Idaho and Yellowstone in the late 1990s. They now total 2,800 ...
