Polyandry and fitness in the western harvester ant, Pogonomyrmex occidentalis - Mol Ecol, Vol 13, Issue 6, pp. 1601-1606 (Abstract) Detailed view on the sociogenetics of single P. occidentalis nests: these western harvester ants have multiple mated queens. Moreover, the results of Wiernasz et al. again are an indication in this species for a fitness benefit for multi-colored colonies: those which had a rich spectrum of genetic patrilines accumulated (and therefore a low relatedness among nest members) were the fastest growing colonies.
