Conservationists have helped to save North America’s largest bird from extinction, but it’s still important to give every chick a chance to fly free.

The fungus that causes white-nose syndrome continues its deadly spread west — but a meeting of bat researchers reveals cause for hope.

The key to saving elephants and other species may lie in the DNA contained in their droppings, says conservation biologist Samuel Wasser.

The “extinction capital of the world” could start losing unique plant species in as little as a month if funding disappears.
