Foraging in response to predators in minnows.

Minnow populations from high-predation and low-predation areas respond differently to a predator.

Gwynedd minnows (from a low-predation site in Wales) totally ceased foraging and eating in the presence of a predator.

Dorset minnows (from a high-predation site in England) curtailed their foraging activity, but not nearly to the extent of Gwynedd minnows.
