Climate change has long been dismissed as a significant stress to New Zealand's native wildlife, but research shows it exacerbates existing threats such as introduced predators and habitat loss.
Millions of miles of fences crisscross the Earth's surface. They divide ecosystems and affect wild species in ways that often are harmful, but are virtually unstudied.
To understand the barriers endangered species face when trying to traverse their habitat, it helps to think of their environment like an electrical circuit board.
Roads and traffic are causing massive mortality of wild animals worldwide and the road network is rapidly expanding. Can the wildlife death toll be stopped?
At current rates, the rattlesnake population in British Columbia could be severely depleted by 2060.
A new study forecasts that thousands of miles of new road construction will cut through tiger habitat across Asia by 2050. Planning can make these projects more tiger-friendly.
Doug Ford's government is undercutting the environment by giving business and development the upper hand.
Expanding cities and farmland have created many small, often isolated patches of vegetation. Long seen as having limited ecological value, a new study shows these are vital for endangered species.
