Data from: The demographic history of populations experiencing asymmetric gene flow: combining simulated and empirical data.

Ivan Paz Viñas, Erwan Quéméré, Lounès Chikhi, Géraldine Loot & Simon Blanchet
Population structure can significantly affect genetic-based demographic inferences, generating spurious bottleneck-like signals. Previous studies have typically assumed island or stepping-stone models, which are characterized by symmetric gene flow. However, many organisms are characterized by asymmetric gene flow. Here, we combined simulated and empirical data to test whether asymmetric gene flow affects the inference of past demographic changes. Through the analysis of simulated genetic data with three methods (i.e. bottleneck, M-ratio and msvar), we demonstrated that...

Data from: Migration and dispersal may drive to high genetic variation and significant genetic mixing: the case of two agriculturally important, continental hoverflies (Episyrphus balteatus and Sphaerophoria scripta)

Lucie Raymond, Manuel Plantegenest & Aude Vialatte
Population structure of pests and beneficial species is an important issue when designing management strategies to optimize ecosystem services. In this study, we investigated for the first time the population structure at a continental scale of two migratory species of hoverflies providing both pest regulation and pollination services [Episyrphus balteatus and Sphaerophoria scripta (Diptera: Syrphidae)]. To achieve this objective, we used two sets of 12 species-specific microsatellite markers on a large-scale sampling from all over...

Data from: ‘Becoming a species by becoming a pest’ or how two maize pests of the genus Ostrinia possibly evolved through parallel ecological speciation events

Denis Bourguet, Sergine Ponsard, Rejane Streiff, Serge Meusnier, Philippe Audiot, Jing Li & Zhen-Ying Wang
New agricultural pest species attacking introduced crops may evolve from pre-existing local herbivores by ecological speciation, thereby becoming a species by becoming a pest. We compare the evolutionary pathways by which two maize pests (the Asian and the European corn borers, ACB and ECB) in the genus Ostrinia (Lepidoptera, Crambidae) probably diverged from an ancestral species close to the current Adzuki bean borer (ABB). We typed larval Ostrinia populations collected on maize and dicotyledons across...
