Ant communities are thought to consist of a competitive hierarchy of interacting species, with an assemblage of subordinate species being structured by a dominant species. Mensurative and behavioral studies suggest a significant role for competition in structuring ant communities, although there are few experimental studies to support this contention. We examined the effect of the dominant ant Iridomyrmex purpureus on the ant fauna of sandstone outcrops in southeastern Australia. We conducted a…

Field tests of interspecific competition in ant assemblages: revisiting the dominant red wood ants.

It is recommended that long-term large-scale experiments be considered essential if they are to distinguish between competing hypotheses in community ecology and found differences in community composition were not owing to differences in measured habitat variables.

Do Dominant Ants Affect Secondary Productivity, Behavior and Diversity in a Guild of Woodland Ants?

The study suggests the negative effects of dominant ant species on non-dominant species may be offset by mechanisms promoting coexistence, and examines the relationship between the richness of non-Dominant ant species and the abundance of a dominant antspecies among forest ant assemblages in the eastern US.

Although the relative importance of competition varied with habitat type, the study demonstrated that in some habitats, dominant ants can control species richness at the assemblage level.

The effect of a dominant ant, Iridomyrmex purpureus, on resource use by ant assemblages depends on microhabitat and resource type

Findings indicate that the dominant ant affects the success of other ants at baits, particularly the ecologically similar Iridomyrmex, however, effects of I. purpureus on other taxa differ between habitats differing in complexity and resources differing in composition and defensibility.

Ant community structure on a small Pacific island: only one native species living with the invaders

Ant assemblages in each habitat had a different ecologically dominant species, and a dominant species in one habitat could be non-dominant and less abundant in another, while on Surprise Island the sole native species dominates in some habitats when confronted by invasive species.

Dominance and species co-occurrence in highly diverse ant communities: a test of the interstitial hypothesis and discovery of a three-tiered competition cascade

It is suggested that dominant species actually promote species richness by neutralizing the effects of subdominant species on subordinate species, and proposes a “competition cascade” where the interactions are through a competition rather than trophic hierarchy.

Strong influences of a dominant, ground‐nesting ant on recruitment, and establishment of ant colonies and communities

The results from the first experimental period, followed by survey results after the decline in P. synanthropica densities suggest that dominant ants can drive community assembly via both recruitment and establishment of colonies within the community.

Constraint and Competition in Assemblages: A Cross‐Continental and Modeling Approach for Ants

The results draw attention to the significance of regional processes in structuring ant assemblages and show that the ascending part of the relationship is largely constrained to take this form not simply as a consequence of stress but also as a result of the shape of abundance frequency distributions.

Patterns of co-occurrence and body size overlap among ants in Florida's upland ecosystems

While competition between species may result in character displacement between similar species, it does not appear to form competition hierarchies at the local scale at which ants actually interact.

An Ant Mosaic Revisited: Dominant Ant Species Disassemble Arboreal Ant Communities but Co‐Occur Randomly

Surprisingly, the suite of five dominant species showed random co-occurrence patterns, suggesting that interspecific competition did not shape their distribution among cocoa trees, and the often complex nature of interactions that structure species-rich tropical arboreal ant assemblages is highlighted.



Colonisation by a dominant ant facilitated by anthropogenic disturbance: effects on ant assemblage composition, biomass and resource use

In areas with I. purpureus, seeds were removed more rapidly from rock, but not vegetation, indicating that resources on rock may be under-exploited by other species, and Regulation of invaded ant assemblages by this dominant ant is thus limited to functionally similar species.

Is the assembly of ant communities mediated by parasitoids

A general framework for integrating the roles of competition and parasitism in the assembly of ant communities is developed and invasions by the red imported fire ant and the Argentine ant are used to show how this new framework can be used to develop testable hypotheses regarding the ecological success (or failure) of invasive ant species.

Ant communities in taiga clearcuts: habitat effects and species interactions

Overall, species interactions seemed to have induced considerable determinism in ant-community succession in young forests by alleviating the effects of nest-site competition and slavemaking.

Niche differentiation of ant species within territories of the wood ant Formica polyctena

This work tested expected interactions among ant species on the basis of a linear competition hierarchy concept consisting of three levels: territorial (top competitors), encounter (aggressive but nonterritorial) and submissive (nonaggressive) species, and focussed on resource partitioning by space and shifts in use of vertical layers of the habitat in presence of the territorial species.

Meat ants as dominant members of Australian ant communities: an experimental test of their influence on the foraging success and forager abundance of other species

Fencing had no effect on pitfall catches of species other than the meat ant, indicating that the effect of meat ants at baits was directly due to interference with foraging workers, and not regulation of general forager abundance.

Patterns of ant community organization in mesic southeastern Australia

The results suggest that ant communities in mesic regions of Australia are less tightly structured than those in the arid zone, and that interspecific competition is a less important factor influencing community organization.

A competition hierarchy among boreal ants: impact on resource partitioning and community structure

Expectations for the nest-distribution pattern of ant species in the late successional habitats of the boreal taiga biome are tested with bait experiments and nest mapping, and the results are modelled by multiway contingency tables.

I report observations on exceptionally diverse ant communities in the seasonally arid tropics of northern Australia that indicate that interference competition from dominant species regulates the

Ant assemblages in the taiga biome: testing the role of territorial wood ants

It is concluded that in the taiga biome territorial wood ants are, after adjusting for physical vicissitudes of the environment, the major structuring force of ant species assemblages.

Interference and Exploitation in a Guild of Woodland Ants

An inverse correlation was found between exploitative and interference ability, which enabled the subordinate species to obtain resources, and in most cases, the speed of bait location was no correlated with distance of the bait from the colony.
