Happy to highlight an essay I wrote together with @marcdemanuel.bsky.social, @natanaels.bsky.social and Anastasia Stolyarova, trying to think through what sets the mutation rate of a cell type in an animal species: www.biorxiv.org/content/10.6... 1/n

New preprint from the lab on bioRxiv, led by Grace Zhang! Quick summary: Lots of studies have examined costs and benefits associated with resistance. Most focus on a single stressor, leaving unclear how resistance shapes fitness and evolution under multiple interacting stresses.

J'ai été interviewé dans l'émission Soyons Nature sur radio campus Montpellier pour expliquer comment l'analyse de l'ADN révèle l'impact des activités humaines sur la biodiversité et l'évolution des espèces marines. www.radiocampusmontpellier.fr/podcast/soyo...

"les cellules buissonnières" now translated into English with the title "Hidden Guests". I loved this reading and I offered 5 to friends and family for christmas last year, a suggestion for you folks.

Does anyone here know about Hi-C heatmaps? What do you think of this one? I feel like the patterns of the first and last five chromosomes are different. Would you agree? What do you think that is? Asking for a friend.

Improving two-step cancer treatment strategies based on evolutionary models, but above all a nice evolutionary rescue model that should be of interest to everyone. #PopGen #CanEcoEvo

Now free to read in Genetics (@genetics-gsa.bsky.social): "Preventing evolutionary rescue in cancer using two-strike therapy" #mathonco study by @srishtipatil.bsky.social, @armaanahmed.bsky.social, Yannick Viossat and me, determining the optimal time to switch treatments. doi.org/10.1093/gene...

We are excited to share our recent work on the surprising robustness of Ancestral Recombination Graph (ARG) inference tools to computational phasing errors, now available on BioRxiv: biorxiv.org/content/10.1.... This work is co-advised by @yundeng.bsky.social and Rasmus Nielsen. 1/7

Roussel, Suh, @fjruizruano.bsky.social & @amdioncote.bsky.social characterized TE content in naturally occurring killifish hybrids, finding higher TE load and accumulation of Neptune subfamilies in hybrids. 🔗 doi.org/10.1093/molbev/msaf266 #evobio #molbio #TEsky

Amanda Sabatino, @jpjahner.bsky.social and I have a new paper on @biorxiv-evobio.bsky.social. Amanda, in her undergraduate thesis work, found variation in Colias colour phenotypes is associated with different metrics of urbanization in Toronto. www.biorxiv.org/content/10.1...

Seeking a postdoc position? ​Balancing selection is a fascinating process: malaria resistance, self-incompatibility,etc. Yet, countless examples remain hidden in genomes! ​If this question intrigues you, the project led by Laure Segurel and Violaine Llaurens (Paris + Lyon) is perfect! urlr.me/Huj2De

Save the date! On behalf of the Society, I’m delighted to announce that the next International Society for Evolution, Ecology and Cancer conference will be taking place in Hersonissos, Crete, on May 21-24, 2026. Abstract submissions will open soon. More details: www.evocancer.com

We have another publication out! 🎉🎉🎉 “Hybrids along a natural–anthropogenic gradient: improving policy and management across all levels of biodiversity.” We explore how to deal with hybrids in conservation — scientifically and practically. A thread 🧵 conbio.onlinelibrary.wiley.com/doi/10.1111/...

Il reste encore des places pour notre formation @ephe-psl.bsky.social à R (27 janvier au 5 février à Paris), avec une focalisation complète sur le traitement de données (pas de statistiques). Il y a un module pour chaque niveau et chaque besoin ! 👇 #rstats #formationcontinue

Do you know the ‘a-prize-every-time’ genome scan method? You should. Popular in the mol ecol literature. Take beasts, stress them in the lab, sequence stressed and unstressed, make filters that anyway retains a list of SNPs or genes, look at their functions, claim selection and unfold your story 🍾

The disappearance (much better word than extinction) of the Neanderthals could be attributed solely to admixture and an asymmetrical demographic wave. The hypothesis takes the form of equations and receives support in this interesting article. www.nature.com/articles/s41...

New paper published together with John Welch on hybrid fitness and how it depends on ploidy and # of distinct ancestries, incl some remarkable fits of data & theory 😶. Keen to hear any thoughts/comments/questions! doi.org/10.1093/gene... Thanks to the team @ Genetics for the smooth experience :)

Again in Roscoff 🤩

Reminder: we still welcome applications! 📩

The second Ph.D. chapter of Diane's thesis is out as a preprint. She studied the joint evolution of autopolyploidy and self-fertilization under a gametophytic self-incompatibility context. Feel free to comment, and congratulations, Diane! www.biorxiv.org/content/10.1...

🧪🌎 We have a conceptually similar method, RDAforest, just published with @kristinaleilani.bsky.social - only it is about predicting genetic adaptation across unsampled landscape doi.org/10.1111/1755...

Proud of the latest edition of my free intro biostats book. gitrepo: github.com/ybrandvain/b... book: ybrandvain.github.io/biostats/ Not complete but at a good point to take a break, and I think its quite usable dm me with comments , ideas etc

Hey Yaniv Brandvain is not on Bluesky but his most recent biostats ebook is live ybrandvain.github.io/biostats/. His stats resources have been so helpful to me as I develop my own stats course, so check it out. Github repo here: github.com/ybrandvain/b...

Microchimerism is one of the most fascinating biological phenomena I've ever studied. But what do we actually know & what do we not know? Our new paper brings together microchimerism researchers to ask the key questions driving the field forward 🧬 advanced.onlinelibrary.wiley.com/doi/10.1002/...

Second day at the Speciation Jacques Monod conference #cjm25, it goes so fast, amazing talks about the biogeography of speciation and hybridization

What a nice start to the Jacques Monod conference #cjm25 on speciation in Roscoff, Britany. What an inspiring lineup of talks and scientists. Even the weather is remarkably welcoming, for now, at least. 🤩

What a nice start and amazing first day of Jacques Monod conference on bridging the micro macroevolution gap #cjm25 plenty of fascinating talks and posters Didn't react quickly enough to illustrate all of them, just catch a few

Good morning Roscoff #cjm25

Just took my breakfast at the #cjm25 speciation conference and around me in a 50m2 breakfast room were seated Nick Barton, Craig Moritz, Amaury Lambert, Maud tenaillon, Ludovic Orlando, Stuart Baird, John Welch, Daniel Matute etc... This density of 🤯🤯🤯 !

Arrived at Roscoff in Brittany for the conference Jacques Monod on #speciation. What a view ! Do we have a hashtag? #cjm25? First plenary lecture was tonight on our (in)hability to predict diversification rates from microevolutionary processes.

We're excited to be recruiting an NIH funded postdoc to work in the Coop lab at UC Davis. We're specifically interested in candidates who are want to work at the intersection of human genetics, GWAS, and population genetics modeling. Please RT

Cross-species cloning in ants 🐜 These two males belong to different species—but share the same mother. How? Why? To celebrate the print release of our last paper in this week’s @nature.com (issue 8084), here’s a thread summarizing the results. Why? Let’s dive in🧵👇 www.nature.com/articles/s41...

Wow 🤩 new bivalve transmissible cancer #TransCan study by the amazing @metzgerm.bsky.social lab on the progression of the disease over long periods.

#fieldwork Again in ports to sample dock mussels that stayed encaged after reciprocal transplants. #MusselsAreCool #UrbanEvolution #MarEvol #PopGen

As every year, I will soon teach an online workshop on DNA methylation and its bioinformatic analysis, using short reads (BS-seq) and long reads (ONT and PacBio) approaches. It will be October 27th-29th (european afternoons and US mornings). Mor info here instats.org/seminar/anal...

Sujet de stage M2 sur la "dock mussel", cet écotype de moules hybrides qui habite dans les ports. L'objectif est de tester si la dock mussel s’est adaptée grâce à sa variance génétique d’admixture ou si l’admixture n’est que le corolaire du contact secondaire entre les deux espèces parentales.

Thanks to @cjgiaimo.bsky.social for this nice article in @nytimes.com (www.nytimes.com/2025/09/15/s...) about our last study (www.nature.com/articles/s41...)

If you’ve heard about our study on ants producing two different species but are still confused about how it works (and don’t have time to read the paper), this 10-minute video made by @bengthomas.bsky.social is very informative: www.youtube.com/watch?v=Z-O4... Paper: www.nature.com/articles/s41...
