Humans rely on the ocean for food, jobs and other resources, but these systems are being stressed to the brink.
One of the most damaging invasive species in the oceans has breached a major barrier – the Amazon-Orinoco river plume – and is spreading along Brazil’s coast. Scientists are trying to catch up.
New research sheds light on why predators don’t evolve to become so aggressive that they eat all their prey – and then go extinct themselves.
The lionfish has few natural predators, and its venomous spines deter potential predators. But there may still be ways to naturally control the growth of this invader’s population.
