cialized predators.

The results are the first to show that the presence or absence of otters influences a terrestrial animal, and that the complex food web linkages can reach as far as five different food chain levels: from sea otters to sea urchins, kelp, marine fish and finally bald eagles.

"Top-down linkages can be very distant from their origin," says Anthony. "The effects of top predators can ripple throughout the ecosystem in ways we're just beginning to understand."
