Finally back home after #ESEB2025. I saw so many inspiring talk last week, and want to once again thank @jevbio.bsky.social for inviting me to speak in the Stearns Prize symposium

A special thanks 💗 to @jevbio.bsky.social @eseb.bsky.social for supporting our attendance and in-person gatherings 🤝, and the Equal Opportunity Initiative @annecharmantier.bsky.social for all their efforts to disseminate and increase #diversity, #inclusivity and #equity in science 🌈

In continued #InverteFest published paper catchup: Sometimes I work on inverts that are not snails or spiders! Like here, where I used my Computer Swearer-At skills to help a friend analyse an experiment with aphids attacked by parasitoid wasps, to see when aphid symbionts help protect them vs not

Well I guess we actually started day 2 #eseb2025 with @evonicki.bsky.social reminding us about the excellent work of the society and how publishing in @jevbio.bsky.social supports this, so win win by publishing in our super society journal.

🧬 Today starts the most relevant event in evolutionary biology: the European Society for Evolutionary Biology (ESEB) Congress (@eseb2025.bsky.social @eseb.bsky.social). 🔝 #IRBBarcelona's group leader @tonigabaldon.bsky.social is the chair of this major event that will gather +1900 participants. 👇

I'm missing #eseb2025 but the lab is well-represented 🤩 📊 Kenneth Aase: genomic prediction of crossover rates (Mon S03) 🎤 Lisa Ammer: sex-differences in CO landscape (Thu 11.30am S28) 📊 Gina Henderson: (no) selection on immunity (Thu S48) 📊 Marie Raynaud: recombination hotspot variation (Thu S02)

And Chedhawat Chokechaipaisarn, whose poster "The consequences of constrained sex allocation under local mate competition" (P02.036) is in Tuesday's session. This is based on his recent paper in Journal of Evolutionary Biology: doi.org/10.1093/jeb/... @jevbio.bsky.social @eseb2025.bsky.social

What you eat when you eat matters! Diet during development vs adulthood affects survival, fertility, and stress resistance — differently in male & female fruit flies. Same calories, different outcomes. Chandrakanth et al.: doi.org/10.1093/jeb/...

New study by Kemlein et al. examines stability of a natural protective symbiosis in the nematode C. elegans: high symbiont colonisation rates are key for immune-protection of the host, even if the symbiont evolves without pathogen selection: doi.org/10.1093/jeb/... @lena-peters.bsky.social

Delighted to have our work on the joint emergence of dioecy and sexual dimorphism be part of this wonderful special issue! I will be presenting this at @eseb2025.bsky.social in a couple of weeks, poster P02.385 on Aug 19th. Feel free to pop by! ☺️

NEW SPECIAL ISSUE JUST RELEASED! Sex unfolded: sex, asex, sexes. Read the introductory editorial by Guest Editors D. Roze, S Glemin, @thomaslenormand.bsky.social & K. Van Doninck here: academic.oup.com/jeb/issue/38/7 Fantastic cover art by Caroline Blanc.

An evolutionary arms race between protective symbionts and parasitoid wasps is taking place inside aphids. But what determines the aphids’ fate? We explore how the origins of symbionts and wasps shape parasitism success: doi.org/10.1093/jeb/... @youn-henry.drosophila.social.ap.brid.gy et al.

Clo et al.’s new review on mating system evo was a great excuse to let me dig into some underexplored ideas in the field: roles of interspecies interactions doi.org/10.1093/jeb/...

The 1st author is here too: follow @tom-is-kean.bsky.social ! His clever idea was to highlight similarities between meiotic drive and inbreeding's "automatic transmission advantage". We ask: given structurally identical(ish) problems, why is what is viewed as paradoxical so different between fields?

Comparative study reports that sex differences in dispersal predict sex differences in cooperation across cooperative birds and mammals. Dispersal likely impacts sex-specific direct benefits or costs of cooperation: doi.org/10.1093/jeb/... Fenner et al. @andyyoung.bsky.social

Why do yeast #de_novo genes have so many transmembrane domains? It's because the genomic regions from which they evolved are super enriched in stretches of A's and T's ! Our work with @timothyfuqua.bsky.social is now published in @jevbio.bsky.social doi.org/10.1093/jeb/...
