Researchers have discovered the oldest known example of a predator-prey “arms race,” based on their study of ancient fossils. This ancient predator-prey relationship took place 517 million years ago ...

Animal survival depends on effective attack and defense strategies, yet how these behaviors arise remains unclear. Addressing ...

I am responding to Greg Hanscom’s editorial referring to the lofty ideal that the mission for wildlife biologists is to work themselves out of a job (HCN, 3/31/03: Dear Friends). It seems to me that ...

In a new study, two species of bacteria grown in a lab reversed their predator-prey relationship after one species was grown at a lower temperature. In a new study, two species of bacteria grown in a ...

A rare example of the reversal of a bacterial predator–prey relationship suggests that such species interactions are more complex than was realized. This is a rare example of the reversal of a ...

A new mathematical model is turning the conventional notion of predator-prey relationships on its head. David Brown and colleagues at the University of California, Davis, have shown that prey ...

Reaction-diffusion systems provide a mathematical framework for describing the interplay between local reactive processes and diffusive transport across space. In ecological settings, these models ...

To better understand the complex interactions between nature’s hunters and hunted, researchers gathered at the the Éco-Laurentides park near Val-Morin, Que., for a game of predator-prey.

The predatory bacterium Myxococcus xanthus (left) slaughtering its prey (right). Black dots are predator aggregates called fruiting bodies and the rippling waves in the contact zone are characteristic ...
