  abstract = {{A}nts are among the most problematic invasive species. {T}hey displace numerous native species, alter ecosystem processes, and can have negative impacts on agriculture and human health. {I}n part, their success might stem from a departure from the discovery-dominance trade-off that can promote co-existence in native ant communities, that is, invasive ants are thought to be at the same time behaviorally dominant and faster discoverers of resources, compared to native species. {H}owever, it has not yet been tested whether similar asymmetries in behavioral dominance, exploration, and recruitment abilities also exist among invasive species. {H}ere, we establish a dominance hierarchy among four of the most problematic invasive ants ({L}inepithema humile, {L}asius neglectus, {W}asmannia auropunctata, {P}heidole megacephala) that may be able to arrive and establish in the same areas in the future. {T}o assess behavioral dominance, we used confrontation experiments, testing the aggressiveness in individual and group interactions between all species pairs. {I}n addition, to compare discovery efficiency, we tested the species' capacity to locate a food resource in a maze, and the capacity to recruit nestmates to exploit a food resource. {T}he four species differed greatly in their capacity to discover resources and to recruit nestmates and to dominate the other species. {O}ur results are consistent with a discovery-dominance trade-off. {T}he species that showed the highest level of interspecific aggressiveness and dominance during dyadic interactions.},
