I've been observing the habits and populations of imported fire ants in
my part of central Texas over the past 8 years, and they seem to be
settling down, reaching an equilibrium. Species which had been driven
out by the ants are beginning to come back, and the ants' population
seems to have stabilized at a level lower than peak levels which occured
several years ago. I would expect the imported fire ant (and other
introduced species) to eventually evolve into sub species and even
separate species in the course of adapting to their new environments, as
their new environments simultaneously adapt to their presence.
