Reef fish interactions and ecosystem function

A study that combined behavioral experiments on French Polynesian coral reef fishes with decision-making models indicates that the tendency of reef fish to feed on algae or flee from predators is influenced by the density and actions of other fish in the area, and that this behavior influenced algal consumption by the fish, suggesting that social interactions can affect the flow of energy and material through ecosystems. - Read at PNAS
