Hi Folks ! Just a few more days to register for the POPGROUP meeting (deadline = this Monday 10/11/2025). Join us in the beautiful city of #Lille just across the Channel for three exciting days of science and more ! www.hautsdefrancetourism.com/destinations... --> populationgeneticsgroup.org.uk

Only a few days left to register and join us in Lille for this first ever French edition of PopGroup!

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...

Autopolyploid establishment under gametophytic self-incompatibility: the impact of self-fertilization and pollen limitation doi.org/10.1101/2025...

Out now! From Jarrod Hadfield and Manas Geeta Arun: How to estimate the additive genetic variance for relative fitness from changes in allele frequency: academic.oup.com/genetics/adv...

Excited to share my first PhD project with my mentor, @johriparul.bsky.social! We examine how Hill–Robertson interference (HRI) in highly selfing species biases estimates of the distribution of fitness effects of new mutations (DFE). doi.org/10.1093/evol... @journal-evo.bsky.social #popgen #evobio

If you like genomics, speciation, and primates, this PhD position is for you! Unraveling the genomic architecture of speciation and gene flow in guenons, a diverse group of African monkeys. Funding through DTP. Do reach out with questions! #genomics #genome_assembly evol.mcmaster.ca/brian/evoldi...

A new free piece released. The Trump "harsh" sanctions on Russia last night were anything but. They actually provide protection for Russia's biggest oil customers to transact business for at least the next 4 weeks--and have no automatic sanction after that. open.substack.com/pub/phillips...

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

Ahahaha

New paper alert! In my second first-author paper from my work on the Isle of Rum Red Deer Project @rumdeerresearch.bsky.social we show, for only the second time in a wild population, that parasites mediate inbreeding depression. www.nature.com/articles/s41...

Coming December 16!

Very happy to announce that the next POPGROUP meeting will take place in Lille on 7-9 January ! Follow ‪@popgroup2026.bsky.social for all updates. 📢 Please share widely ! 📢‬

Exciting news! The next #PopGroup meeting will take place in Lille 🍟, France, 7–9 January 2026 – just 1 hour by train from London, Brussels, and Paris. This year, PopGroup will also host ALPHY, the annual meeting of Evolutionary Genomics. More info: populationgeneticsgroup.org.uk See you there !

C. elegans is a real animal and we set out to understand how it comes to have its distinctive biogeography. Its ancestral center of diversity is in the higher elevation forests of Hawaii. Its closest relatives are spread across east Asia. Did they travel from Asia? [Preprint 🧵]

Check out this cool work from @crouxevo.bsky.social and others, congrats!!! 🥳 Rapid establishment of species barriers in plants compared with that in animals | Science www.science.org/doi/10.1126/...

I forgot to mention it here, my last PhD chapter (Wolbachia in Culex) is now published in @molbioevol.bsky.social I think it's a cool study, give it a try 😌 Includes: wPip cid repertoires from all around the world (Nanopore seq. of PCR products), crosses, stability + toxicity tests in cell lines.

I'm very happy to share that our paper describing the evolution of sex chromosomes in brown algae is out!🎉 This project was a long journey, but it came together into a nice story 🧬 🌊 Grateful to everyone who helped along the way!

How does stochasticity in learning impact the accumulation of knowledge and the evolution of learning? https://www.biorxiv.org/content/10.1101/2025.08.26.672373v1

Pre-print now out on bioRxiv! If you saw my talk at #eseb and want more info, here it is:

I'll be presenting poster 327 at #ESEB2025 today - come have a look if you're interested in the evolution of sex and haploid-diploid life cycles!

If you’d like to chat about deleterious hitchhiking under balancing selection, come and check my poster number 231 this afternoon! #ESEB2025

If you like cooperation, dispersal, modelling, or you just want to have a chat, come to see me poster P03.050 #ESEB2050

Will be presenting this work today at #eseb2025 poster P02.184, come by if interested about whether we should expect recombination suppression on sex chromosomes should evolve through modifiers on the X or the Y

Does selfing allow or even lead to massive genome reshuffling, expansion and sky high homozygousity? Come and find out at posters 29 and 42 this afternoon, only at #eseb2025 and learn about an organism whose genome looks like it went through a blender and came out high repetitive and homozygous.

My poster P02.385 is now up on its board! Come say hi if you want to learn about the role of sexual conflict in transitions from combined to separate sexes is plants! 🌱 #ESEB2025

After 10 years of work, a complete telomere-to-telomere gap-free genome for C. elegans finally exists: it has 106 Mb rather than the textbook 100.3 Mb, and up to 366 additional genes. genome.cshlp.org/content/35/8...
