1. The fire ant, Solenopsis invicta, is a globally distributed invasive ant that is largely restricted to disturbed habitats in its introduced range. For more than half a century, biologists have believed its success results from superior competitive abilities relative to native ant species, as well as an escape from their natural enemies. 2. [...] Key Result We used large volumes of hot water to kill fire ant colonies, and only fire ant colonies, on experimental plots in pastures, and found that populations and diversity of co-occurring ants did not subsequently increase. 3. These results are contrary to classical predictions and indicate that S. invicta is not a superior competitor that suppresses native ants, and that the low diversity and abundance of native ants in degraded ecosystems does not result from interaction with fire ants. Instead…Expand
Ecological dominance of the red imported fire ant, Solenopsis invicta, in its native range
TLDR
It is revealed that the red imported fire ant ecologically dominated other terrestrial ants in its native range; however, other species were able to be numerically dominant or co-dominant in its presence. Expand
Ant community and habitat limit colony establishment by the fire ant, Solenopsis invicta
TLDR
The results suggest that ant community assembly proceeds primarily by queen habitat choice and secondarily by filtering and competition, and that by landing in disturbed habitat with its reduced native ant population, newly mated fire ants queens increase their chances of successful colony establishment. Expand
Experimental evidence that human impacts drive fire ant invasions and ecological change
TLDR
It is shown that human activity, not biological invasion, is the primary driver of negative effects on native communities and of the process of invasion itself, and it is proposed that fire ants may be representative of other invasive species that would be better described as disturbance specialists. Expand
The Role of Habitat in the Persistence of Fire Ant Populations
TLDR
Observations and experiments show that S. invicta colonies rarely persist in the native habitat of these pine forests, probably because they are not replaced when they die. Expand
Introduced fire ants can exclude native ants from critical mutualist-provided resources
TLDR
The results provide the first experimental evidence that introduced ants compete for access to mutualist-provided carbohydrates with native ants and that these carbohydrates represent critical resources for both introduced and native ants. Expand
The effects of disturbance on the red imported fire ant (Solenopsis invicta) and the native ant community
TLDR
Pre-treatment differences in ant community assemblage between blocks suggest that past disturbance may have more of an effect on the distribution of ant species, but this observation is not associated with historical soil disturbance. Expand
The fire ant Solenopsis saevissima and habitat disturbance alter ant communities
TLDR
Ant species richness was significantly lower in the presence of S. saevissima in the riparian forest, forest edges and meadows, illustrating that this ant species has a negative impact on the ant communities in addition to the impact of natural- and man-made disturbances. Expand
Traits allowing some ant species to nest syntopically with the fire ant Solenopsis saevissima in its native range
TLDR
It is likely that over the course of evolution each of these ant species acquired the capacity to live syntopically with S. saevissima through its own set of traits, where colony size, cuticular compounds which do not trigger aggressiveness and submissive behaviors complement each other. Expand
Mechanisms of Competitive Displacement of Native Ant Fauna by Invading Myrmica rubra (Hymenoptera: Formicidae) Populations
TLDR
Results indicate competitive superiority by M. rubra with respect to native ant communities of the northeastern North America and suggest direct aggression and competitive exclusion at food resources can lead to local native displacement. Expand
Imported fire ants near the edge of their range: disturbance and moisture determine prevalence and impact of an invasive social insect.
TLDR
Habitat disturbance and species invasions interact in natural systems, making it difficult to isolate the primary cause of ecosystem degradation, andalyses of co-occurrence indicate that reduced species density in wet-undisturbed sites arises from negative species interactions between native ants and S. invicta, but these same data suggest that the high native species density at sites in dry-disturbed environments does not result from facilitation.

LONG-TERM IMPACTS OF AN ARTHROPOD-COMMUNITY INVASION BY THE IMPORTED FIRE ANT, SOLENOPSIS INVICTA
TLDR
The results of this study indicate that the impact of such invasive ants may be greatest during and shortly after the initial phase of an invasion. Expand
Invasion of Polygyne Fire Ants Decimates Native Ants and Disrupts Arthropod Community
TLDR
The ecological impacts of a polygyne fire ant invasion on ants and other surface—active arthropods at a field station in central Texas indicate that polygyn fire ants pose a substantial threat to the biodiversity of native arthropod communities. Expand
Invasion of red imported fire ants (Hymenoptera: Formicidae): microgeography of competitive replacement
The invasion of Brackenridge Field Laboratory, Austin, Texas, by the multiple-queen form of the red imported fire ant, Solenopsis invicta Buren, was monitored for 3 yr. This invasion provides a rareExpand
Interaction of Hybrid Imported Fire Ants (Solenopsis invicta × S. richteri) with Native Ants at Baits in Southeastern Tennessee
TLDR
The results suggest that, like the red imported fire ant, Solenopsis invicta, the hybrid fire ant outcompetes native ants in disturbed habitats. Expand
Positive Association Between Densities of the Red Imported Fire Ant, Solenopsis invicta (Hymenoptera: Formicidae), and Generalized Ant and Arthropod Diversity
TLDR
Results suggest that S. invicta densities as well as the diversities of other ants and arthropods are regulated by common factors (e.g., productivity). Expand
The Causes and Consequences of Ant Invasions
TLDR
Experimental studies and research focused on the native range ecology of invasive ants will be especially valuable contributions to this field of study. Expand
Conservation of biodiversity in an area impacted by the red imported fire ant, Solenopsis invicta (Hymenoptera: Formicidae)

TLDR
A conservation study was conducted at Camp Swift, Bastrop County, Texasto to determine if the red imported fire ant, Solenopsisinvicta, could be selectively managed to protect endemic ant diversity, and resulted in significantly higher ant diversity in the area where S. invicta was managed by prescription bait treatments.

COMPETITIVE MECHANISMS UNDERLYING THE DISPLACEMENT OF NATIVE ANTS BY THE INVASIVE ARGENTINE ANT
TLDR
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.

Impact of Solenopsis invicta Buren Suppression on Arthropod Ground Predators and Pest Species in Soybean
TLDR
Ground arthropods were monitored in soybean using pitfall traps in the 2000 and 2001 growing seasons to determine their response to selected fire ant controls, and reduced fire ant density plus chemical treatment impacted the abundance of certain ground predators. Expand
Invasion, competitive dominance, and resource use by exotic and native California grassland species
TLDR
Native species reinvaded exotic grasslands across experimentally imposed nitrogen, water, and disturbance gradients and revealed that native perennial species were strong competitors, and exotic annuals are not superior competitors but rather may dominate because of prior disturbance and the low dispersal abilities and extreme current rarity of native perennials.
