Aquatic predators affect carbon-storing plant life
Species at top of freshwater food web can indirectly limit buildup of carbon dioxide in the atmosphere

In ecosystems around the world, big guys eat littler guys, who in turn eat plants and other organisms at the base of the food web. A study now finds that removing top predators in freshwater environments allows their prey to flourish — and overgraze on plants and algae. The result of the missing plant matter: a 93 percent reduction in uptake and storage of carbon dioxide.
Several research teams have explored the importance of predators in protecting organisms that store carbon, notes ecolog...
