New Caledonia must be considered as a very old Darwinian island, a concept that offers many more fascinating opportunities of study, as it is contradicted by geological evidence indicating long Palaeocene and Eocene submersions and by recent biogeographic and phylogenetic studies.
Clonal reproduction by males and females in the little fire ant
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.

Age estimates reveal an origin after the Triassic-Jurassic mass extinction (older than previously thought), followed by the diversification of major lineages during Pangaean and Gondwanan breakups, and it is hypothesized that this pattern is better explained by the concomitant reduction of arid environments starting in the mid-Cretaceous.

The evolutionary genetics of introduced populations of the invasive ant Wasmannia auropunctata at a worldwide scale are studied, and it is suggested that invasive clonal populations may have evolved within human modified habitats in the native range, and spread further from there.
Threats on Pacific islands: the spread of the Tramp Ant Wasmannia auropunctata (Hymenoptera: Formicidae)

Invasions are not an abnormality in the evolutionary process, but an increase in their rate could lead to a dramatic homogenization of fauna and flora.
Immediate impacts of invasion by Wasmannia auropunctata (Hymenoptera: Formicidae) on native litter ant fauna in a New Caledonian rainforest
Wasmannia auropunctata appears to be a highly competitive ant that dominates the litter by eliminating native ants in New Caledonia and reinforces the idea of common evolutionary traits leading to higher competitiveness in a new environment.
Higher level molecular phylogeny of darkling beetles (Coleoptera: Tenebrionidae)
This study reconstructs the first higher level phylogeny based on DNA sequence data for the species‐rich darkling beetles, and investigates the evolutionary history of Tenebrionidae using multiple phylogenetic inference methods to analyse a dataset consisting of eight gene fragments across 404 taxa.
Characterization and PCR multiplexing of polymorphic microsatellite loci for the invasive ant Wasmannia auropunctata
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.

A dominance hierarchy among four of the most problematic invasive ants (Linepithema humile, Lasius neglectus, Wasmannia auropunctata, Pheidole megacephala) that may be able to arrive and establish in the same areas in the future is established.
