A group with the extraordinary sex ratios in Blainville female allocation and greater male mortality compared to the demographically stable resident cannot invade an empty environment. Methods General Assumptions In birds and butterflies sex determination follows the system. Each set of parameters identifies two runs: one with high and one with low initial invader extraordinary sex ratios in Blainville.
