Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

Looking forward to speaking @dzg2025berlin.bsky.social in Berlin on Anthropocene Biology in Eastern Europe and Beyond. I will talk about the implications of #war on wildlife. Sadly, science meets reality when my departure to Berlin was delayed due a #drone attack in Poland.

Absolutely stunning story! I'll just drop this line here: "Clonal males may thus be regarded as organelles at the superorganism level, resulting from the integration of this alien genome into a colony that directly replicates it."

Why do males and females often differ in traits? The expected answer: selection. But our new paper in GENETICS shows that genetic drift alone can generate sexual dimorphism — even when male & female optima are the same

Do ectotherms age more strongly in warm environments? And if so, does it mean reduced fitness and population viability in a warmer world? We investigated these questions in a recent study based on an experiment with Daphnia magna (1/7) @t-ergon.bsky.social @biovitenskap.bsky.social

@cnrsecologie.bsky.social regrette profondément l'adoption de cette loi à la vision court-termiste & ses conséquences graves sur l’environnement, qui méprise santé & bien-être de la population & le rôle des espèces sauvages dans la prod. agricole. La communauté scientifique n'a pas été entendue.

In 2010 (SMBE Lyon) I gave a talk about the impact of GC-biased gene conversion (gBGC) on functional sequence evolution. I argued that, because gBGC promotes G and C alleles irrespective of their fitness effect, it should generate some genetic load. 1/5

Our preprint on the statistical analysis of reaction norms and plasticity is recommended by @peercommunityin.bsky.social Evolutionary Biology, and will soon be published in the @peercomjournal.bsky.social! Check out nice thread by previous postdoc (and now great PI!) @pdevillemereuil.bsky.social 👇
