tramp ant

The occurrence of highly invasive (tramp) ants (Passera 1994) is of concern, and Saks and Carroll (1980) showed that tramp ants could become abundant in disturbed areas while remaining uncommon in nearby undisturbed forests. Exotic tramp ant species have been found to produce major changes in abundance and diversity of invertebrate species in other regions (Lubin 1984; Zenner-Polania 1994).
