Abstract	— A study of the Formicidae community of littoral backdunes at Campo dell'Oro (Ajaccio, Corsica) and of the competition between two invasive taxa: Linepithema humile (Mayr, 1868) and Tapinoma nigerrimum (Nylander, 1856).— The Corsican Formicidae community suffers today from important changes affecting coastal backdunes environments. These changes are linked to the recent expansion of two invasive species: the alien species Linepithema humile (Mayr, 1868) and Tapinoma nigerrimum (Nylander, 1856), considered as a native species. This study explores for the first time the organization of Formicidae community in a typical site of coastal backdunes in Corsica (Campo dell'Oro at Ajaccio), as well as the effects of the combined presence of L. humile and T. nigerrimum on the local myrmecofauna. In this context, different sampling techniques have been used (e.g. nest recording, workers trapping) in order to analyse several parameters that may affect Formicidae communities: species diversity, taxa distribution, habitats and nests and workers densities. These analyses highlight the important effects of several biotic and abiotic factors (e.g. vegetation type, organic matter, humidity) on the distribution and organization of ants from Corsican beaches. The data also show a clear spatial exclusion between L. humile and T. nigerrimum due to competition between the two species. Finally, unlike the native species, L. humile seems unable to coexist with high diversity of species in the coastal backdunes.
