Characterization and PCR multiplexing of polymorphic microsatellite loci for the invasive ant Wasmannia auropunctata Inra
Fournier, D.; Foucaud, J.; Loiseau, A.; Cros-Arteil, S.; Jourdan, H.; Orivel, J.; Le Breton, J.; Chazeau, J.; Dejean, A.; Keller, L.; Estoup, A..
Highly polymorphic genetic markers provide a useful tool for estimating genetic parametersin studies of the evolution of sociality in insects. We isolated and characterized 12 polymorphicmicrosatellite loci in the invasive ant, Wasmannia auropunctata, and described experimental conditions for PCR (polymerase chain reaction) multiplexing and simultaneously genotyping these loci in two sets of five and seven markers. The number of alleles per locus ranged from two to 14 and the observed heterozygosity ranged from 0.233 to 0.967. Moreover, results of cross-species amplification tests are reported in three other species of Wasmannia and in two species of the genus Allomerus

Ecologically heterogeneous populations of the invasive ant Wasmannia auropunctata within its native and introduced ranges Inra
Orivel, J.; Grangier, J.; Foucaud, J.; Le Breton, J.; Andrès, F.X.; Jourdan, H.; Delabie, J.H.C.; Fournier, D.; Cerdan, P.; Facon, B.; Estoup, A.; Dejean, A..
The biology of most invasive species in their native geographical areas remains largely unknown. Such studies are, however, crucial in shedding light on the ecological and evolutionary processes underlying biological invasions.The present study focuses on the little fire ant 2. Wasmannia auropunctata, a species native to Central and South America that has been widely introduced and which has become invasive throughout the tropics. We characterise and compare several ecological traits of native populations in French Guiana with those in one of its introduced ranges, New Caledonia.We found ecologically heterogeneous populations of 3. W. auropunctata coexisting in the species’ native geographical area. First, we found populations restricted to naturally...

Reproductive system, social organization, human disturbance and ecological dominance in native populations of the little fire ant, Wasmannia auropunctata Inra
Foucaud, J.; Orivel, J.; Fournier, D.; Delabie, J.H.C.; Loiseau, A.; Le Breton, J.; Cerdans, P.; Estoup, A..
The invasive ant species Wasmannia auropunctata displays both ecologically dominant and non-dominant populations within its native range. Three factors could theoretically explain the ecological dominance of some native populations of W. auropunctata: (i) its clonal reproductive system, through demographic and ⁄ or adaptive advantages; (ii) its unicolonial social organization, through lower intraspecific and efficient interspecific competition; (iii) the human disturbance of its native range, through the modification of biotic and abiotic environmental conditions. We used microsatellite markers and behavioural tests to uncover the reproductive modes and social organization of dominant and non-dominant native populations in natural and human-modified...

Sex and clonality in the little fire ant Inra
Foucaud, J.; Fournier, D.; Orivel, J.; Delabie, J.H.C.; Loiseau, A.; Le Breton, J.; Kergoat, G.; Estoup, A..
Reproduction systems are controlling the creation of new genetic variants as well as how natural selection can operate on these variants. Therefore, they had historically been one of the main foci of evolutionary biology studies. The little fire ant, Wasmannia auropunctata, has been found to display an extraordinary reproduction system, in which both males and female queens are produced clonally. So far, native sexual populations of W. auropunctata have not been identified. Our goals were to identify such sexual populations and investigate the origins of female parthenogenesis and male clonality. Using mitochondrial DNA and microsatellite markers in 17 native populations, we found that traditional sexual populations occurred in W. auropunctata and are...

Worldwide invasion by the little fire ant: routes of introduction and eco-evolutionary pathways Inra
Foucaud, J.; Orivel, J.; Loiseau, A.; Delabie, J.H.C.; Jourdan, H.; Konghouleux, D.; Vonshak, M.; Tindo, M.; Mercier, J.L.; Fresneau, D.; Mikissa, J.B.; McGlynn, T.; Mikheyev, A.S.; Oettler, J.; Estoup, A..
Biological invasions are generally thought to occur after human aided migration to a new range. However, human activities prior to migration may also play a role. We studied here the evolutionary genetics of introduced populations of the invasive ant Wasmannia auropunctata at a worldwide scale. Using microsatellite markers, we reconstructed the main routes of introduction of the species. We found three main routes of introduction, each of them strongly associated to human history and trading routes. We also demonstrate the overwhelming occurrence of male and female clonality in introduced populations of W. auropunctata, and suggest that this particular reproduction system is under selection in human-modified habitats. Together with previous researches...
