Abstract: Pond lives A study of ponds in a nature sanctuary in Florida shows how species interactions can lead to ecological cascades that spill over from one habitat to another. Four of the eight ponds contain predatory fish that eat dragonfly larvae. Fewer adult dragonflies emerge, and as they would normally eat the insects that pollinate plants around the ponds, the plants near ponds occupied by fish benefit from higher pollinator densities than those around ponds without fish: QED.
