The article combines a modelling approach with an extensive survey of known data to show that in most prey, male-biased predation will have a stabilizing effect on the predator-prey dynamics (that is, such predation may lead to a predator-prey equilibrium), while female-biased predation will usually be destabilizing and may lead to extinction of the populations. This ecological viewpoint might provide an alternative or supplementary explanation, other than sexual selection, as to why male-biased predation prevails in nature.
