ESSs with two types of players II (intra- and interspecific competition between haploid species)

The investigation of strategy evolution resulting from animal behavior is continued using a new approach to multispecies evolutionary games. A different interpretation of the known result that contestants in asymetrical games choose pure strategies is proven. This leads to a classification of all evolutionarily stable strategies (ESS) when there is no selection from interspecific competitions. In case the dimension of the strategy space is restricted as in a diallelic haploid model, the phase portrait of the evolutionary dynamics is illustrated. The results are then compared with the previous approach and to models of sex dependent selection in randomly mating diploid species.
