Fear of predators may be a bigger killer than the predators themselves

When biologists consider the effects that predators have on their
prey, they shouldn't just count the number of individuals consumed.
According to a University of Rhode Island ecologist, they must also
examine the effects of fear.
URI Assistant Professor Evan Preisser said that fear of being eaten
can reduce population densities as much or even more than the actual
quantities of individuals killed by predators.
"Prey are far from helpless victims of predators," said Preisser.
"They employ a wide array of defensive strategies to protect
themselves. But the costs of these strategies may have a larger impact
on their population than the direct effect of being eaten."

This effect reminds me of how in the US fear of terrorism is causing
much, much, more damage than any actual incidents of terrorism.
