When conservationists relocate species, they don’t always account for the pathogens hitching a ride, and the consequences of introducing them to a new environment.

His career was dedicated to understanding and protecting frog populations.

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

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.

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.
