A changing climate, growing human populations and widespread fires contributed to the last major extinction event − can we prevent another?

New findings from the La Brea Tar Pits in southern California suggest human-caused wildfires in the region, along with a warming climate, led to the loss of most of the area’s large mammals.

Forensic evidence suggests Paleo-Americans hunted mastodons, mammoths and other megafauna in eastern North America 13,000 years ago

How did ancient moa survive the ice age – and what can they teach us about modern climate change?

DNA from ancient eastern moa bones is unlocking the secrets of their survival during the last ice age, and providing lessons for today’s threatened species.

Connecting fragmented wolverine habitat is essential for their conservation

The key to protecting wolverines around the world is to reduce trapping, minimize predator control pressures, and to protect and connect large blocks of intact habitat they need to survive.
