Experience influences aggressive behaviour in the Argentine ant.
All animals interact with conspecifics during their life, and nearly all also display some form of aggression. An enduring challenge, however, is to understand how the experiences of an individual animal influence its later behaviours. Several studies have shown that prior winning experience increases the probability of initiating fights in later encounters. Using behavioural assays in the labo...
متن کاملIntraspecific competition influences the symmetry and intensity of aggression in the Argentine ant
Cooperative social groups rely on the ability to distinguish members from nonmembers. Accordingly, social insects have evolved a variety of systems that allow discrimination of nest mates from non–nest mates. In this study, we show that experience can modify patterns of intraspecific aggression in Argentine ants (Linepithema humile). In laboratory experiments, we found that aggression between c...
متن کاملThe worldwide expansion of the Argentine ant
Biological invasions by non-indigenous species are widely recognized as a significant component of human-caused global environmental change, often resulting in a significant loss in the economic value, biological diversity and function of invaded ecosystems (Elton, 1958; D’Antonio & Vitousek, 1992; Lodge, 1993; Vitousek et al., 1996, 1997). Studies of the phylogeographic structure (Stone & Sunn...
متن کاملGenetic structure, behaviour and invasion history of the Argentine ant supercolony in Australia
Biological invasions have significant ecological, evolutionary and economic consequences. Ants are exemplary invaders and their invasion success is frequently attributed to a shift in social structure between native and introduced populations. Here, we use a multidisciplinary approach to determine the social structure, origin and expansion of the invasive Argentine ant, Linepithema humile, in A...
متن کاملGeographical variation in Argentine ant aggression behaviour mediated by environmentally derived nestmate recognition cues
Social insects use a complex of recognition cues when discriminating nestmates from non-nestmate conspecifics. In the Argentine ant, Linepithema humile, recognition cues can be derived from exogenous sources, and L. humile acquires prey-derived hydrocarbons that are used in nestmate discrimination. We studied Argentine ant population-level distinctions in response to external recognition cues. ...
