The flavopilosa group was proposed by Wheeler and colleagues in 1962. In taxonomic terms, it seems to be a monophyletic group, belonging to virilis-repleta radiation of the Drosophila subgenus. However, the exact position ...

Rapid evolutionary radiations are difficult to resolve because divergence events are nearly synchronous and gene flow among nascent species can be high, resulting in a phylogenetic “bush”. Large datasets composed of sequence ...

Organisms rapidly diversifying across unstable environments such as mountain tops provide substantial challenges for resolving evolutionary histories and delimiting species. The Liolaemus leopardinus clade is a group of ...

Background Genetic exchange in Trypanosoma cruzi is controversial not only in relation to its frequency, but also to its mechanism. Parasexual genetic exchange has been proposed based on laboratory hybrids, but population ...

The taxonomic identification of octocorals is based on morphological characters, known for their high plasticity with the environment. This hinders the delimitation and identification of species, which translates in biases ...
