A recently introduced, ecologically dominant, exotic ant species, Nylanderia fulva, is invading the Southeastern United States and Texas. We evaluate how this invader impacts diversity and abundance of co-occurring ants and other arthropods in two grasslands. N. fulva rapidly attains densities up to 2 orders of magnitude greater than the combined abundance of all other ants. Overall ant biomass increases in invaded habitat, indicating that N. fulva exploits resources not fully utilized by the… 

Sugar is an ant’s best friend? Testing food web theory predictions about trophic position and abundance in an invasive ant (Nylanderia fulva)

Classical food web theory predicts that species at the base of food webs will be more abundant than those at the top. Likewise, it’s hypothesized that feeding at lower trophic positions (e.g.,

Widespread Chemical Detoxification of Alkaloid Venom by Formicine Ants

Widespread venom detoxification among ants in the subfamily Formicinae is reported, indicating that alkaloid venoms are targets of detoxification grooming and influences ant-assemblages through a variety of ecological pathways.

Behavioral responses to numerical differences when two invasive ants meet: the case of Lasius neglectus and Linepithema humile

Two of the world’s most invasive ants, Linepithema humile and Lasius neglectus, are destined to overlap in range as they continue to spread throughout Europe. Although L. humile arrived first, and is

The global spread and invasion capacities of alien ants

Quantifying the impacts of symbiotic interactions between two invasive species: the tawny crazy ant (Nylanderia fulva) tending the sorghum aphid (Melanaphis sorghi)

The establishment of new symbiotic interactions between introduced species may facilitate invasion success. For instance, tawny crazy ant (Nylanderia fulva Mayr) is known to be an opportunistic

Supercolonial structure of invasive populations of the tawny crazy ant Nylanderia fulva in the US

This study investigated the population genetics, colony structure and levels of aggression in the tawny crazy ant, Nylanderia fulva, which was recently introduced into the United States from South America and found that this species experienced a genetic bottleneck during its invasion lowering its genetic diversity by 60%.

Tunneling Performance Increases at Lower Temperatures for Solenopsis invicta (Buren) but not for Nylanderia fulva (Mayr)

The hypothesis that N. fulva is capable of tunneling in temperatures as low as 15.0 °C is supported, confirming that this ant can also perform a behavior that is used by other ants for cold avoidance.

Esterase in Imported Fire Ants, Solenopsis invicta and S. richteri (Hymenoptera: Formicidae): Activity, Kinetics and Variation

Esterases play a crucial role in toxic tolerance of insects and it is hypothesized that the more invasive S. invicta would have a higher esterase activity than S. richteri, a more successful invasive species.



Imported fire ants near the edge of their range: disturbance and moisture determine prevalence and impact of an invasive social insect.

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.

The worldwide transfer of ants: geographical distribution and ecological invasions

AimThis is the first comprehensive account of the biogeography of ants transferred and at least temporarily established outside their native habitat.

Plant-based food resources, trophic interactions among alien species, and the abundance of an invasive ant

The study shows that the distribution and abundance of different plant species could have important effects on the abundance of S. invicta through their effect on the ants’ food resources, and is consistent with the hypothesis that the emergence of novel trophic interactions among invasive species can promote the abundances of invasive ants.

Metatranscriptomics and Pyrosequencing Facilitate Discovery of Potential Viral Natural Enemies of the Invasive Caribbean Crazy Ant, Nylanderia pubens

Pyrosequencing the transcriptome of field-collected samples of N. pubens has identified at least three sequences that are likely of viral origin and, in which, N. pubs serves as host, which is especially important at this early stage of developing a knowledgebase for this new pest.

The Causes and Consequences of Ant Invasions

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