Data from: Cryptic differences in colour among Müllerian mimics: how can the visual capacities of predators and prey shape the evolution of wing colours?

Violaine Llaurens, Mathieu Joron & Marc Théry
Antagonistic interactions between predators and prey often lead to co-evolution. In the case of toxic prey, aposematic colours act as warning signals for predators and play a protective role. Evolutionary convergence in colour patterns among toxic prey evolves due to positive density-dependent selection and the benefits of mutual resemblance in spreading the mortality cost of educating predators over a larger prey assemblage. Comimetic species evolve highly similar colour patterns, but such convergence may interfere with...

Data from: Genetic architecture of sensory exploitation: QTL mapping of female and male receiver traits in an acoustic moth

Sylvain Alem, Réjane Streiff, Brigitte Courtois, Saliha Zenboudji, Denis Limousin & Michael D. Greenfield
The evolution of extravagant sexual traits by sensory exploitation occurs if males incidentally evolve features that stimulate females owing to a pre-existing environmental response that arose in the context of natural selection. The sensory exploitation process is thus expected to leave a specific genetic imprint, a pleiotropic control of the original environmental response and the novel sexual response in females. However, females may be subsequently selected to improve their discrimination of environmental and sexual stimuli....

Data from: A genetic polymorphism affecting reliance on personal versus public information in a spatial learning task in Drosophila melanogaster

Julien Foucaud, Anne-Sophie Philippe, Celine Moreno & Frederic Mery
Organisms that face behavioural challenges can use different types of information to guide their decisions. First, they can use the personal information they sample in their environment. Second, they can use the inadvertent social information provided by the behaviour of conspecifics or heterospecifics (i.e. public information). Currently, little is known about the interaction between genetic variation and the use of personal versus public information in natural populations. Here, we investigated whether a natural genetic polymorphism...

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...
