Tracking predators to protect Southern Ocean Ecosystems
n a rapidly changing world, we need to know which areas warrant protection from current and forthcoming threats. This is hard to do objectively in the vast Southern Ocean. However, identifying where predators go also tells us where their prey can be found. If multiple predator species and their dive...
