The facultative enslaver Formica sanguinea Latr. uses as slaves F. fusca L. and other species of the subgenus Serviformica For. Earlier observations have shown or suggested that strong territorial wood-ant species, by defending their own territories, interfere with raids by F. sanguinea such that colonies of potential slave species gain protection against raids. At the population level, such protection should be visible as higher nest densities of F. fusca within than outside wood-ant territories, when both areas are within raiding distance of F. sanguinea. Here we tested this hypothesis by mapping nest densities of F. fusca. As expected, nest densities of F. fusca were higher within than outside wood-ant territories. In contrast, nest densities of two aggressive species, Lasius platythorax Seifert and L. niger (L.), unsuitable as slaves, were as expected lower within than outside wood-ant territories. Our results concur with earlier studies based on pitfall trapping, baiting experiments, and in situ observations on raids. The results also show that the positive impact of indirect protection provided by wood ants against raids may outweigh the direct negative impact of wood ants on F. fusca nesting within their territories. We discuss the geographic and habitat cooccurrences of wood ants, enslavers and potential slave species, and coverage of efficient indirect protection of potential slaves against raids.

By protecting their territory against all territorial ants, Formica rufa L. indirectly protected F. fusca L., nesting within their territory, against F. sanguinea Latr. raids. The permanent costs to F. fusca caused by highly aggressive F. rufa within their territories were outweighed by the benefits obtained by F. rufa’s protection against periodic raids of F. sanguinea. We interprete our findings in the light of the hierarchy competitive framework as follows.

The wood ant Formica polyctena Först, is a territorial species, a regular top dominant of ant communities in forests. Its colonies defend their whole foraging areas (territories) against other territorial ants, including F. sanguinea Latr., a common facultative slave-maker. The most frequent ‘victim’ ol F. sanguinea is F. fusca L., a ubiquitous submissive ant species. On the basis of some earlier observations, the presumption was made that F. polyctena, when defending its own territories, would indirectly protect F. fusca colonies, which nest within these territories, from F. sanguinea raids. It was expected that F. fusca should be more abundant in F. polyctena territories, than in F. sanguinea territories, while other subordinate ants, which are not potential slaves of F. sanguinea, should not show such difference. This hypothesis was supported by the results of the baiting experiments carried out in the Białowieża Forest, NE Poland. The findings are discussed in the context of interspecific competition hierarchy in ants.

The species composition, nest density, structure and ecological profile of an ant community were studied within a transect encompassing the forest interior, forest edge and a belt-shaped clearing in a moist mixed pine forest habitat (Querco roboris-Pinetum) in the Kampinos Forest (Central Poland) in the context of direct and indirect human impact and the bioindicator importance of ants. Altogether, 19 ant species were found; the most abundant ones (in respect of number of nests) in the entire habitat under study were Temnothorax crassispinus (Karav.) and Myrmica rubra (L.). All analysed parameters of individual subcommunities, except for nest density (highest on the forest edge, lowest in the cleared belt), showed a gradient pattern of variability, with species richness and the index of general diversity increasing and the dominance index decreasing within the transect from the forest interior to the cleared belt. Differences between the two subcommunities from the forested area (forest interior and forest edge), both highly dominated by T. crassispinus, were, in every way, much smaller than those between either of them and the subcommunity from the cleared area, where M. rubra prevailed.

The paper presents four cases of territorial ant colonies interfering in the course of Formica sanguinea Latr. raids against slave species which nest next to or in their territories. In three cases, Formica rufa L., when protecting its own territory, forced out (one case) or held (two cases) a raiding column of F. sanguinea, thus “saving” local Formica fusca L. nests from danger. In one case, Lasius fuliginosus (Latr.) did not let a F. sanguinea column pass its territory; to reach its target (a colony of Formica cinerea Mayr), the column had to by-pass the foreign territory.

Formica fusca L. slaves from colonies of Polyergus rufescens (Latr.) tend to establish small homospecific satellite nests close to a main nest. P. rufescens maintains the integrity of a mixed colony by means of peculiar integration raids (Czechowski 2005). The present paper describes the history of a group of such satellite nests, temporarily separated from the main nest by a foraging route of Formica polyctena Först. impassable to P. rufescens. The ex-slaves had managed to adopt F. fusca gynes and raised some homospecific worker pupae before the F. polyctena route disappeared and P. rufescens started to raid their nests. During the raids, the mutual attitude of the slave-makers and the ex-slaves quickly evolved from hostility to friendly relations.
