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 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.
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.
