Dyck was widely respected for working alongside indigenous groups as he studied polar bears on their ancestral lands.

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.

Plant species officially reported to be lost are in fact persevering in the wild, in seed banks or botanical gardens, or as other species now recognized to be taxonomic synonyms.

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.
