Experimental studies and research focused on the native range ecology of invasive ants will be especially valuable contributions to this field of study.

Using microsatellite markers, it is shown that a population bottleneck has reduced the genetic diversity of introduced populations, and this loss is associated with reduced intraspecific aggression among spatially separate nests, and leads to the formation of interspecifically dominant supercolonies.
Patterns of spread in biological invasions dominated by long-distance jump dispersal: Insights from Argentine ants.

The invasion history of the Argentine ant (Linepithema humile), a widespread invasive species, is reconstructed at three spatial scales using a combination of literature review, museum records, and personal surveys to improve the predictive power of future modeling efforts.
COMPETITIVE MECHANISMS UNDERLYING THE DISPLACEMENT OF NATIVE ANTS BY THE INVASIVE ARGENTINE ANT

The findings imply that Argentine ants secure a majority of available food resources where this species comes into contact with native ants, and may be able to break the competitive trade-off constraining native ants because of their unique colony structure and because they have escaped their natural enemies.
ROLE OF ABIOTIC FACTORS IN GOVERNING SUSCEPTIBILITY TO INVASION: A TEST WITH ARGENTINE ANTS
Experimental data demonstrate how the abiotic environment impinges on both colony-level activity and colony growth in the Argentine ant and provide a general explanation for the patterns observed at the community level.
Effect of Argentine ant invasions on ground-dwelling arthropods in northern California riparian woodlands

It is suggested that Argentine ants and the native ants they displace interact with the ground-dwelling arthropods of these habitats in a similar manner.
Factors governing rate of invasion: a natural experiment using Argentine ants
- D. Holway
- Environmental ScienceOecologia
- 1 June 1998
It is suggested that abiotic suitability is of paramount importance in determining rate of invasion for the Argentine ant, a widespread invasive species of northern California.
Behavioral and Genetic Differentiation Between Native and Introduced Populations of the Argentine Ant

Results identify a possible mechanism for the widespread success of the Argentine ant in its introduced range by comparing the genetic diversity, behavior, and ecology of Argentine ants in their native range to introduced populations.
Trophic ecology of invasive Argentine ants in their native and introduced ranges
- C. Tillberg, D. Holway, E. LeBrun, A. Suarez
- Environmental ScienceProceedings of the National Academy of Sciences
- 26 December 2007
The hypothesis that Argentine ants shift their diet after establishment as a result of resource depletion and increasing reliance on plant-based resources, especially honeydew-producing Hemiptera is supported.
The role of opportunity in the unintentional introduction of nonnative ants.

- 22 November 2005
An extensive database of ant species unintentionally transported to the continental United States is developed and data is used to test how opportunity and species-level ecological attributes affect the probability of establishment.
