Competition and coexistence in an insular ant community, a manipulation experiment (Hymenoptera: Formicidae)

Abstract: Colonies of the red wood ant Formica truncorum were transferred to offshore islets in the Gulf of Finland previously lacking this or other sg. Formica species. The result of this ecological manipulation experiment shows that F. truncorum by weakening populations of Lasius niger may at the same lime boost the nest numbers of Lasius jlavus and Leptothorax sp. The findings confirming previous notions of stable competition between L. niger and L. flavus indicate that Leptothorax sp. may also be involved in the competitive network. Such findings as the hostility between F. truncorum and L. niger are discussed.
