Abstract We generated mitochondrial DNA (mtDNA) sequence data from 402 individuals of the fire ant Solenopsis invicta collected from 11 native populations and analyzed these data using a combination of demographic, phylogenetic, and phylogeographic methods to infer features of the evolutionary history of this species. Prior expectations regarding high levels of genetic structure and isolation by distance among populations were supported by the data, but we also discovered several unanticipated… Expand
Genetic variation and structure in native populations of the fire ant Solenopsis invicta: evolutionary and demographic implications
TLDR
It is concluded that nominal S. invicta in its native range comprises multiple entities that are sufficiently genetically isolated and diverged to have embarked on independent evolutionary paths and to have come into secondary contact without regaining the capacity to freely interbreed. Expand
Evolutionary history of the little fire ant Wasmannia auropunctata before global invasion: inferring dispersal patterns, niche requirements and past and present distribution within its native range
TLDR
The Bayesian phylogeographic analysis suggests that the common ancestor of the two main clades of W. auropunctata occurred in central Brazil during the Pliocene, which is concordant with the adaptation of this originally tropical ant species to temperate climates prior to its successful establishment in the Mediterranean region. Expand
Putative native source of the invasive fire ant Solenopsis invicta in the USA
TLDR
This attempt to identify the source(s) of the red imported fire ant (Solenopsis invicta) in the southern USA utilizing data from three classes of genetic markers and employing Bayesian clustering simulations, assignment and exclusion tests, and phylogenetic and population genetic analyses concludes that the Mesopotamia flood plain near Formosa, Argentina represents the most probable source region.

Population Genetics of the Invasive Fire Ant Solenopsis invicta (Hymenoptera: Formicidae) in the United States
TLDR
Bayesian analyses showed that study populations most distant from the claimed site of entry, Mobile, AL, have diverged most from the hypothetical founder population, consistent with an invasion scenario in which the ants spread outward from Mobile through repeated subfounder events. Expand
Pliocene and Pleistocene events shaping the genetic diversity within the central corridor of the Brazilian Atlantic Forest
TLDR
It is argued that, for some Atlantic forest endemic species, especially those resistant to very small fragments of forest, such as D. lucida, the small putative refuges were as important as, or even more important than, larger and stableRefuges for the creation and maintenance of diversity, adding another piece to the puzzle of the mechanisms underlying local endemism. Expand
Species delimitation in native South American fire ants
TLDR
The discovery of genetically distinct populations within both S. invicta and S. richteri suggests the presence of previously unrecognized (cryptic) species, implying that the group is actively radiating species and that morphological divergence generally does not keep pace with the development of reproductive isolation and neutral genetic divergence in this process.

Population genetic structure of the red imported fire ant, Solenopsis invicta, in Taiwan
TLDR
This is the first study to investigate the population and colony structure of fire ants in Taiwan and results represent an important contribution to the ongoing efforts aimed at eradicating this invasive pest. Expand
Molecular characterization of fire ants, Solenopsis spp., from Brazil based on analysis of mtDNA gene cytochrome oxidase I

Molecular phylogeny of fire ants of the Solenopsis saevissima species-group based on mtDNA sequences.
The systematics of South American fire ants (Solenopsis saevissima species-group) has been plagued by difficulties in recognizing species and their relationships on the basis of morphologicalExpand
Introduction Pathway Analysis Into New Zealand Highlights a Source Population 'Hotspot' in the Native Range of the Red Imported Fire Ant (Solenopsis invicta)
TLDR
There was no single introduction pathway for this invasive ant in New Zealand that can be specifically targeted by biosecurity authorities, and sequence data suggested that the New Zealand nests ultimately originated in north east and north central Argentine. Expand

TLDR
A detailed history of how a widespread terrestrial vertebrate responded to episodic Pleistocene glacial events in North America is provided and illustrates how complementary methods of data analysis can be used to disentangle recent and ancient effects on the genetic structure of a species. Expand

TLDR
This study confirmed the existence of five major evolutionary lineages that evolved in geographic isolation during the Pleistocene and have remained largely allopatric since then and provided evidence for the role of biological factors in addition to that of physical isolation in limiting introgressive hybridization among major trout lineages.

TLDR
Genetic incompatibilities generally may be insufficient to create effective postzygotic barriers to interspecific gene flow in this group of ants, given that hybrids between these species in the United States suffer little apparent loss of fitness. Expand
Distribution of the Two Social Forms of the Fire Ant Solenopsis invicta (Hymenoptera: Formicidae) in the Native South American Range
TLDR
It is found that polygyny occurs in a mosaic pattern with respect to the more common monogyne (single queen) social form in the fire ant Solenopsis invicta Buren, a pattern superficially similar to that seen in the introduced range in the United States. Expand
Limited phylogeographical structure across Eurasia in two red wood ant species Formica pratensis and F. lugubris (Hymenoptera, Formicidae)
TLDR
Contraction of the distribution range of each species to a single refugial area at different times during the late Pleistocene and a subsequent population expansion seem to be an explanation for the lack of phylogeographical structure across most of Eurasia in species that are ecologically associated with the boreal forest.

Isolation by distance and sharp discontinuities in gene frequencies: implications for the phylogeography of an alpine insect species, Carabus solieri
TLDR
This study highlights strongly the possible confounding contribution of barriers to gene flow to IBD pattern and emphasizes the utility of the model‐based clustering analysis to identify such barriers. Expand
Phylogeography of subterranean and surface populations of water lice Asellus aquaticus (Crustacea: Isopoda)
TLDR
By superimposing the subterranean mode of life on the phylogeographical pattern, three independent cave colonizations could be inferred within a distance of < 100 km, suggesting caves were invaded after the ancestral surface populations became isolated through vicariant fragmentation. Expand
Separating population structure from population history: a cladistic analysis of the geographical distribution of mitochondrial DNA haplotypes in the tiger salamander, Ambystoma tigrinum.
TLDR
This paper shows how a nested cladistic analysis of geographical distances can be used to test the null hypothesis of no geographical association of haplotypes, test the hypothesis that significant associations are due to restricted gene flow, and identify patterns of significant association that is due to historical events. Expand
Phylogeography of Cerastoderma glaucum (Bivalvia: Cardiidae) across Europe: a major break in the Eastern Mediterranean
TLDR
The results imply a long-term isolation of populations in parts of the Eastern Mediterranean or Black Sea basins through the Pleistocene, and patterns of shallower, star-phylogeny type diversity within the Ponto-Caspian phylogroup and in the Baltic Sea area may represent more recent, post-glacial generation of variation.
