Reproduction systems are controlling the creation of new genetic variants as well how natural selection can operate on these variants. Therefore, they had historically been one main foci evolutionary biology studies. The little fire ant, Wasmannia auropunctata, has found to display an extraordinary reproduction system, in which both males and female queens produced clonally. So far, native sexual populations W. auropunctata have not identified. Our goals were identify such investigate...

A unique reproductive system has previously been described in Wasmannia auropunctata, a widespread invasive ant species, where males are produced clonally, female queens parthenogens, and workers sexually. However, these findings were mostly based on samples originating from only limited part of the native range species South America. We used microsatellite markers to uncover modes displayed by large number nests collected various W. auropunctata populations introduced 40 years ago into New...

Background Direct oral anticoagulants (DOACs) account for an increasing proportion of prescriptions in patients with non-valvular atrial fibrillation (NVAF) primary care. Inappropriate dosing DOACs is a common problem, under-dosing being particular issue. However, conflicting results have been reported about the factors independently associated inappropriate dosing. Aim To describe among CACAO French nationwide general practice cohort, and to identify DOAC doses. Design setting...
