A predator’s mere potential presence shapes the behavior of an entire ecosystem.

Evidence

We saw neither hide nor hair of him, but his personality pervaded the wilderness; no living beast forgot his potential presence, for the price of unwariness was death. No deer rounded a bush, or stopped to nibble pods under a mesquite tree, without a premonitory sniff for el tigre. No campfire died without talk of him. — Aldo Leopold, A Sand County Almanac, 507
