Figure 2

Behavioural interactions of Argentine ants within sites. Frequency of aggressive and non-aggressive behavioural interactions between nestmates and non-nestmates within each site. The frequency represents the total number of interactions (aggressive and non-aggressive) of all three nests within a site for within and between nest interactions observed over 10 minutes. Levels of significance shown by (ns) p > 0.05 and (***) P < 0.001 (Chi-Square test). Locality abbreviations: Elim = Elim, Port = Porterville, Cal = Caledon, Stell = Stellenbosch, SW = Somerset West, Jonk = Jonkershoek, Bell = Bellville, and Bred = Bredasdorp.
