The world's largest land mammal could help us end cancer. The fastest bird is showing us how to solve a century-old engineering mystery. The oldest tree is giving us insights into climate change. The loudest whale is offering clues about the impact of solar storms. For a long time, scientists ignored superlative life forms as outliers. Increasingly, though, researchers are coming to see great value in studying plants and animals that exist on the outermost edges of the bell curve.

Several years ago, ecologist Lauren E. Oakes set out from California for Alaska's old-growth forests to hunt for a dying tree: the yellow-cedar. With climate change as the culprit, the death of this species meant loss for many Alaskans. Oakes and her research team wanted to chronicle how plants and people could cope with their rapidly changing world. Amidst the standing dead, she discovered the resiliency of forgotten forests, flourishing again in the wake of destruction, and a diverse community of people who persevered to create new relationships with the emerging environment.
