The role of endosymbionts in the evolution of haploid-male genetic systems in scale insects (Coccoidea) [PDF]
, 2012 There is an extraordinary diversity in genetic systems across species, but this variation remains poorly understood. In part, this is because the mechanisms responsible for transitions between systems are often unknown.

Restricted Gene Flow among Lineages of Thrips tabaci Supports Genetic Divergence Among Cryptic Species Groups. [PDF]
PLoS ONE, 2016 Knowledge of the relative influence of population- versus species-level genetic variation is important to understand patterns of phenotypic variation and ecological relationships that exist among and within morphologically indistinguishable cryptic ...

Does Wolbachia infection affect Trichogramma atopovirilia behaviour? [PDF]
Unisexual Trichogramma forms have attracted much attention due to their potential advantages as biocontrol agents. Fitness studies have been performed and understanding the cost that Wolbachia may inflict on their hosts will help in deciding if Wolbachia

Alternative reproductive strategies: a queen perspective in ants [PDF]
, 2000 Ant colonies are commonly thought to have a stable and simple family structure, with one or a few egg-laying queens and their worker daughters. However, recent genetic studies reveal that the identity of breeding queens can vary over time within colonies.
