A study yields insights into how predator-prey dynamics may shift with climate change, but many questions remain.

The behavior is the first example of a mammal mimicking a more-dangerous species.

Mongolian rodents join the ranks of earthworms and beavers as known ecosystem engineers.

Moving collectively on the water surface could help protect schools of fish from being eaten by predatory birds.

When observed under a microscope, guard hairs from mice resemble optical sensors used in thermal cameras to detect heat, according to a new study.

The Scientist speaks with organismal biologist Xavier Glaudas about possible reasons for his recent finding that male Montpellier snakes cannibalize female conspecifics.

In areas where gray wolf populations have grown, motorists have fewer collisions with deer, likely due to the predators keeping deer away from roadways.

As they close in for the kill, the flying mammals use quieter echolocation to focus on the chase.

As some conservationists and researchers begin to return large carnivores to areas where they once roamed, scientists intensify efforts to study the ecological roles of predators.

A global decline of large carnivores has motivated scientists to understand the animals’ ecological roles, and consider whether reintroducing them can help restore ecosystems.

The release of gray wolves in Yellowstone decades ago still stands as one of the few examples of a predator reintroduction, and the lessons learned continue to be debated. New projects aim to do it again.

The invertebrate predators prey on and lay their eggs near emerging tadpoles, potentially threatening the conservation of endangered frogs, researchers find.

Eastern gray squirrels appear to ease up on vigilance behavior when the birds sound calm.

The bioluminescent Anomalops katoptron can coordinate its schooling behavior after dark. 

Nest predation of shorebirds that raise young in the Arctic are up threefold since the mid-20th century, and climate change may be to blame, according to a study.

The bombardier beetle forced its devourer to vomit it out by releasing explosive, toxic chemicals.
