In the United States, studying the territoriality of nonnative ants such as the red fire ant, a species native to South America, may seem unlikely to yield generalizable results-but it does have distinct advantages. Most importantly, whereas the fire ant shares habitat with many ant competitors in South America, its communities in the United States are much simpler. Colonizable landscape is blanketed almost continuously with fire ant territories, so all territorial boundaries are with other fire ant colonies. We can study the complexities of territoriality in almost pure, continuous populations of a single species, without the complicating influences of other competitors. Furthermore, the high densities of many fire ant populations ensure that interactions among competing colonies will be intense and obvious.
