Blackwell Synergy - Oikos, Vol 103, Issue 3, pp. 469-478: Colonisation by a dominant ant facilitated by anthropogenic disturbance: effects on ant assemblage composition, biomass and resource use (Abstract): "In areas with Iridomyrmex purpureus, seeds were removed more rapidly from rock, but not vegetation, indicating that resources on rock may be under-exploited by other species. Regulation of invaded ant assemblages by this dominant ant is thus limited to functionally similar species, and this may be due to its use of resources that are unexploited in its absence."
