We describe genetic structure at microgeographical scales in two social forms of the introduced fire ant Solenopsis invicta using nuclear and mitochondrial markers. Fire ant populations in northern Georgia, U.S.A. are structured in fundamentally different ways at the two genomes. Virtually all nuclear genetic variation resides within sampling sites; no differentiation was apparent between the social forms and only minimal differentiation was found among sites in only one social form (the… 

Population Genetics of the Invasive Fire Ant Solenopsis invicta (Hymenoptera: Formicidae) in the United States

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.

A TEST OF QUEEN RECRUITMENT MODELS USING NUCLEAR AND MITOCHONDRIAL MARKERS IN THE FIRE ANT SOLENOPSIS INVICTA

The results suggest that nonnestmate queen recruitment occurs at a high frequency in introduced populations of this species and kin selection models that rely on the recruitment of only nestmate queens to explain the persistence of polygyny in ants do not apply to polygyne S. invicta in its introduced range.

Mitochondrial markers in the ant Leptothorax rugatulus reveal the population genetic consequences of female philopatry at different hierarchical levels

It is found significant population viscosity (isolation‐by‐distance) at the mitochondrial level in only the predominantly polygynous population, which supports the theoretical prediction that female philopatry leads to mtDNA‐specific population structure.

Distribution of the Two Social Forms of the Fire Ant Solenopsis invicta (Hymenoptera: Formicidae) in the Native South American Range

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.

Population genetic structure of the red imported fire ant, Solenopsis invicta, in Taiwan

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.

Patterns of population subdivision and gene flow in the ant Nothomyrmecia macrops reflected in microsatellite and mitochondrial DNA markers

The Australian endemic ant Nothomyrmecia macrops is renowned for having retained a large proportion of ‘primitive’ morphological and behavioural characters. Another less studied peculiarity of this

RESTRICTED EFFECTIVE QUEEN DISPERSAL AT A MICROGEOGRAPHIC SCALE IN POLYGYNOUS POPULATIONS OF THE ANT FORMICA EXSECTA

Investigation of the microgeographic genetic structure of mitochondrial haplotypes in polygynous populations of the ant Formica exsecta shows that effective queen dispersal is extremely restricted even at a small geographical scale, consistent with the idea that ecological constraints are an important selective force leading to the evolution and maintenance of polygyny.

PHYLOGEOGRAPHIC STRUCTURE OF THE FIRE ANT SOLENOPSIS INVICTA IN ITS NATIVE SOUTH AMERICAN RANGE: ROLES OF NATURAL BARRIERS AND HABITAT CONNECTIVITY

A major genetic break between S. invicta mtDNA haplotypes that coincides with the Mesopotamia wetlands region of South America, resulting in two higher level nested clade groupings is revealed and contrasting patterns of genetic differentiation within these two major groups are identified.

Sympatry of Polygyne and Monogyne Colonies of the Fire Ant Solenopsis invicta (Hymenoptera: Formicidae)

Thepolygyne region in northcentral Florida is more accurately described as an area where relatively high frequencies of polygyne colonies are interdispersed with single queen colonies.

Extended family structure in the ant Formica paralugubris: the role of the breeding system

It was estimated that about 99.8% of the reproducing queens and males originated from within the nest, or from a nearby nest, and contrast with the common view that unicoloniality is coupled with unrestricted gene flow among nests.

AN UNUSUAL PATTERN OF GENE FLOW BETWEEN THE TWO SOCIAL FORMS OF THE FIRE ANT SOLENOPSIS INVICTA

Allele and genotype frequencies at 12 neutral polymorphic protein markers, as well as the numbers of alleles at the sex‐determining locus (loci), are shown here to be consistent with significant ongoing gene flow between two geographically adjacent populations of Solenopsis invicta that differ in colony queen number.

Effects of social organization on gene flow in the fire ant Solenopsis invicta

Variation in mito-chondrial DNA and two unique nuclear genes are examined to demonstrate that gene flow between sympatric social forms of the fire ant Solenopsis invicta is restricted to only one of four possible routes, demonstrating the potential for social selection to generate significant barriers to gene flow and to initiate reproductive isolation.

COMPLEX COLONY STRUCTURE IN SOCIAL INSECTS: I. ECOLOGICAL DETERMINANTS AND GENETIC CONSEQUENCES

Combined data from seasonal censuses, allozyme electrophoresis, and worker hostility tests showed that a population of M. punctiventris in Vermont was strictly monogynous and seasonally polydomous, but in New York, the population genetic structure reflected microgeographic subdivision and inbreeding.

Evolution of social organization can be important in generating intrinsic selective regimes that channel subsequent social evolution and in initiating the development of significant population genetic structure, including barriers to gene flow important in cladogenesis.

Effect of a founder event on variation in the genetic sex-determining system of the fire ant Solenopsis invicta.

It is concluded that diploid males have increased in frequency in introduced populations because of a loss of allelic diversity at the sex-determining locus (loci) of S. invicta, which has generated a substantial increase in the estimated segregational genetic load associated with production of sterile diploids males in introducing populations over the load in native populations.

The amount of gene flow and population viscosity were studied in two red ant species, Myrmica ruginodis and M. rubra, and suggest that new nests are commonly founded close to the mother nest, most probably by division of existing nests.
