1 furthermore indicates that the outcome of competition between populations of consumers may also apply to distributions of species occupying a habitat. If the resource points shown in Fig. Coexistence is immediately possible if the invading asexuals have a smaller inhibitory effect on the exploitative abilities of the sexuals than the sexuals have on themselves. Above this threshold, it is self-regulation of asexuals through intraspecific competition that halts their population growth before extinction of the sexual population. We therefore conclude that the twofold cost of males to the growth capacity of the sexual population does not automatically pose a threat to the survival of the sexual strategy.
Males are less costly to species with high growth capacities.
Strong intraspecific competition favours coexistence after an asexual invasion, giving the sexual strategy more time than was previously thought 29 in which to express its well known evolutionary advantages over asex.
