  abstract = {{A}nts figure prominently among the worst invasive species because of their enormous ecological and economic impacts. {H}owever, it remains to be investigated which species would be behaviourally dominant when confronted with another invasive ant species, should two species be introduced in the same area. {I}n the future, many regions might have suitable environmental conditions for several invasive ant species, as predicted under climate change scenarios. {H}ere, we explored interactions among several highly invasive ant species, which have been shown to have overlapping suitable areas. {T}he aim of this study was to evaluate the performance in interference competition of seven of the world's worst invasive ant species ({A}noplolepis gracilipes, {P}aratrechina longicornis, {M}yrmica rubra, {L}inepithema humile, {L}asius neglectus, {W}asmannia auropunctata and {P}heidole megacephala). {W}e conducted pairwise confrontations, testing the behaviour of each species against each of the six other species (in total 21 dyadic confrontations). {W}e used single worker confrontations and group interactions of 10 versus 10 individuals to establish a dominance hierarchy among these invasive ant species. {W}e discovered two different behavioural strategies among these invasive ants: three species displayed evasive or indifferent behaviour when individuals or groups were confronted ({A}. gracilipes, {P}a. longicornis, {M}. rubra), while the four remaining species were highly aggressive during encounters and formed a linear dominance hierarchy. {T}hese findings contrast with the widespread view that invasive ants form a homogeneous group of species displaying the 'invasive syndrome', which includes generally aggressive behaviour. {T}he dominance hierarchy among the four aggressive species may be used to predict the outcome of future competitive interactions under some circumstances. {Y}et, the existence of several behavioural strategies renders such a prediction less straightforward.},
