Argentine ants are limited dispersers. In their native range, they form multi-queen supercolonies that are large, but constrained by competition with neighboring supercolonies. Recently one supercolony has been able to invade the Mediterranean climates of North America, Australia and the actual Mediterranean. Members of this giant supercolony do not fight each other. However, this large-scale cooperation should break down over time, decreasing the invasion success of this species. Our project will develop an agent-based model to explore how, where and over what timeframe this might this happen.
