Invasion and predation in aquatic ecosystems
This article reviews biological invasions in which predation (or its absence) plays a major role in the success of the invader. Examples are described in which the invader out-competes native species for the same food, and cases in which the invader consumes valued native species. In many instances,...

Examples are described in which the invader out-competes native species for the same food, and cases in which the invader consumes valued native species.
