Abstract
Simulation models are described that examine the effect of a patchy population structure on the evolution of competition strategies. The results of the models suggest that a patchy population structure will make the evolution of scramble competition strategies more likely than in a single undivided population. The outcome of the models depends on the details of the population structure, in particular the number of individuals that found patches, the number of generations of competition within a patch, and the point at which founding females mate can all affect the evolutionary outcome. The results of the models are compared to those of previous models examining the effects of a structured population on the evolution of female-biased sex ratios, and altruistic behavior. The results of the model may help to explain the patterns of larval competition strategies observed in bruchid beetles.
