Clonal reproduction by males and females in the little fire ant
TLDR
Findings show that the haplodiploid sex-determination system provides grounds for the evolution of extraordinary genetic systems and new types of sexual conflict in the little fire ant Wasmannia auropunctata. Expand
Influence of queen phenotype, investment and maternity apportionment on the outcome of fights in cooperative foundations of the ant Lasius niger
TLDR
Consider pleometrotic associations in L. niger as a ‘best of a bad job’, whereby the benefits of joint founding and the probability of surviving the conflict might be sufficient for smaller queens to embark on cooperative foundations. Expand
Sex and clonality in the little fire ant.
TLDR
This work found that traditional sexual populations occurred in W. auropunctata and are likely the recent source of neighboring clonal populations, and investigates the origins of female parthenogenesis and male clonality. Expand
Genetic Structure, Nestmate Recognition and Behaviour of Two Cryptic Species of the Invasive Big-Headed Ant Pheidole megacephala
TLDR
This study shows that populations of P. megacephala in Cameroon adopt a unicolonial social structure, like invasive populations in Australia, however, the size of the supercolonies appears several orders of magnitude smaller in Africa, which implies competition between African supercolony and explains why they persist over evolutionary time scales.

Significant reproductive skew in the facultatively polygynous ant Pheidole pallidula
TLDR
This study investigated how queens share parentage in polygynous (multiple queen) colonies of the Mediterranean ant Pheidole pallidula and revealed for the first time a trade‐off in the relative contribution of nestmate queens to gyne and worker production. Expand
Characterization and PCR multiplexing of polymorphic microsatellite loci for the invasive ant Wasmannia auropunctata
TLDR
Twelve polymorphic microsatellite loci are isolated and characterized in the invasive ant Wasmannia auropunctata and experimental conditions for PCR multiplexing and simultaneously genotyping these loci in two sets of five and seven markers are described. Expand
Investigation of the population genetic structure and mating system in the ant Pheidole pallidula
TLDR
It is demonstrated, through analysis of mother–offspring combinations and the use of direct sperm typing, that each queen is inseminated by a single male, and it is indicated that colonies are genetically differentiated and form a population exhibiting significant isolation‐by‐distance, suggesting that some colonies originate through budding. Expand
Genetic diversity, worker size polymorphism and division of labour in the polyandrous ant Cataglyphis cursor
TLDR
The hypothesis that multiple mating is favoured because increased genetic diversity within colonies translates into more polymorphic workers and facilitates genetic polyethism in eusocial Hymenoptera is not supported. Expand
Population genetic structure, worker reproduction and thelytokous parthenogenesis in the desert ant Cataglyphis sabulosa
TLDR
Analysis of population genetic structure, mating system, worker reproduction and parthenogenesis in the desert ant Cataglyphis sabulosa indicated that colonies are genetically differentiated and form a population exhibiting no isolation-by-distance pattern, consistent with the independent foundation of new colonies. Expand
Facultative asexual reproduction and genetic diversity of populations in the humivorous termite Cavitermes tuberosus
TLDR
Another candidate species, Cavitermes tuberosus, is investigated, and data add to the phylogenetical dispersion and diversity of modalities of AQS in termites, supporting a multiple evolutionary origin of this process. Expand
