Ecology. The lion and the lamb find closure.
Interactions between enemies and their victims are found in all ecological communities. But what has puzzled ecologists is how victims and enemies coexist together for long periods of time without all of the victims being killed off. In a Perspective, Hastings explains a new model (Keeling et al.), which shows that variation in the distribution of victim and enemy species acts as a stabilizing factor in interactions between them.
