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… Expand

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
A TEST OF QUEEN RECRUITMENT MODELS USING NUCLEAR AND MITOCHONDRIAL MARKERS IN THE FIRE ANT SOLENOPSIS INVICTA
  • M. Goodisman, K. Ross
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1998
TLDR
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. Expand
Mitochondrial markers in the ant Leptothorax rugatulus reveal the population genetic consequences of female philopatry at different hierarchical levels
TLDR
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. 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
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
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 thisExpand
RESTRICTED EFFECTIVE QUEEN DISPERSAL AT A MICROGEOGRAPHIC SCALE IN POLYGYNOUS POPULATIONS OF THE ANT FORMICA EXSECTA
TLDR
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. Expand
Population genetics of the socially polymorphic ant Formica podzolica
TLDR
It is found that there is no significant differentiation between the sympatric social forms of F. podzolica, nor did differentiation among populations appear to be affected by colony social organization, and unexpected patterns of genetic structure may have resulted from differences either in the spatial distribution of the social forms or in their social flexibility. Expand
PHYLOGEOGRAPHIC STRUCTURE OF THE FIRE ANT SOLENOPSIS INVICTA IN ITS NATIVE SOUTH AMERICAN RANGE: ROLES OF NATURAL BARRIERS AND HABITAT CONNECTIVITY
TLDR
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. Expand
Sympatry of Polygyne and Monogyne Colonies of the Fire Ant Solenopsis invicta (Hymenoptera: Formicidae)
TLDR
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. Expand

AN UNUSUAL PATTERN OF GENE FLOW BETWEEN THE TWO SOCIAL FORMS OF THE FIRE ANT SOLENOPSIS INVICTA
  • K. Ross, D. Shoemaker
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1993
TLDR
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
TLDR
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.

  • 1997
TLDR
Evidence is presented that selection acting independently on Pgm-3 and Gp-9, in conjunction with gene flow from the alternate, "monogyne" social form of this species, may explain the origin of disequilibrium between the two loci in polygyne fire ants. Expand
COMPLEX COLONY STRUCTURE IN SOCIAL INSECTS: I. ECOLOGICAL DETERMINANTS AND GENETIC CONSEQUENCES
TLDR
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.

ECOLOGY AND EVOLUTION OF SOCIAL ORGANIZATION: Insights from Fire Ants and Other Highly Eusocial Insects
TLDR
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. Expand
Effect of a founder event on variation in the genetic sex-determining system of the fire ant Solenopsis invicta.
TLDR
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.

Estimates of heterozygosity in two social insects using a large number of electrophoretic markers
An extensive electrophoretic survey of enzyme and protein markers was conducted for a haplodiploid eusocial insect, the red imported fire ant (Solenopsis invicta), and for a diploid communal insect,Expand

TLDR
Highly divergent haplotypes coexist in this population of toque macaques and are maintained between social groups that exchange male migrants, and thus nuclear genes, frequently, suggesting that they may be spatially segregated even on this micro‐geographic scale. Expand

It is reported that several important elements of social organization in multiple-queen nests differ consistently and dramatically between ants in Argentina and the United States. Expand

TLDR
If these populations are at a drift-migration equilibrium, the chloroplast DNA restriction fragment length polymorphism data and previous mitochondrial frequency data from the same individuals are consistent with gene flow that is differential through seeds and pollen, according to theoretical predictions.
