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.
Conservation biologist John Ewen discusses the recent reintroduction of Tasmanian devils to mainland Australia after a 3,000-year absence and issues that need to be considered when bringing long-departed animals back into an area.
Buzzfeed uncovers trophy hunters among the ranks of the International Union for Conservation of Nature, which, critics say, may be impeding wildlife protection.
They’ve survived volcanic eruptions, but one Caribbean island’s mountain chicken frogs might need help from scientists to escape the lethal chytrid fungus.
Population reductions in species such as sparrows and blackbirds reflect a concerning pattern of declining biodiversity across the continent, researchers find.
