Figure 3From: Behavioural and chemical evidence for multiple colonisation of the Argentine ant, Linepithema humile, in the Western Cape, South AfricaBehavioural interactions of Argentine ants from different sites. Non-metric Multidimensional Scaling (MDS) plot showing all aggressive and non-aggressive behavioural interactions for paired nests between sites. Analyses were conducted using the categories aggression and non-aggression. The separation incorporated colony interactions that included Elim 3 and those that did not. All interactions that included Elim 3 ("green triangle") and those that excluded Elim 3 ("blue trianlgle") grouped separately indicating a distinct boundary between Elim and all other sites.Back to article page
