Chromosomal inversions are both engines of repeatability and innovation. They drive parallel genetic divergence between snail ecotypes across Europe, while also harbouring local variants that contribute to site-specific trait variations and adaptation: doi.org/10.1093/jeb/... Pajot et al 2026

Two years later, an updated graph: It's still very bad for young women and maths in France, due to a structural reform of high schools. Source: Mélanie Guenais on LinkedIn www.linkedin.com/posts/melani...
numbers of high school students, men and women, in math class in France in the "general" path. About the same numbers since 2000 (initially a bit more men),  an increase from 2010, then in 2019 a reform, with numbers crashings; men's recover at their 2000 level, while women remain much lower

New results on Littorina fabalis ecotypes! 🐌 Inversions aren't just enabling parallel adaptation to wave exposure in France & Sweden, they're also hotspots for site-specific differences, including a striking color QTL associated with one inversion but only in France. www.biorxiv.org/content/10.6...

It is with joy and exhaustion I'd like to announce the release of Harpy v2 🎆. What's different? Uh, almost everything. The changelog is so long that even I don't want to read it. BUT. IT WORKS WITH WGS DATA. AND MOST LINKED READ TECH. it just works 🙂 github.com/pdimens/harpy

GitHub - pdimens/harpy: Process linked-read data, from raw sequences to phased haplotypes, batteries included. Works with WGS too!

Short insertions and deletions are abundant but are they useful markers in genome scans for divergent selection? Hybrid zones in Littorina suggest they can add to information from SNPs, despite stronger purifying selection: doi.org/10.1093/jeb/... Perini, Butlin and @anjamwestram.bsky.social

Abstract. Polymorphic short insertions and deletions (INDELs ≤ 50 bp) are abundant, although less common than single nucleotide polymorphisms (SNPs). Evide

Great work by Ambre Ribardière, Thomas Broquet and co' on mosaic hybrid zones between two species of marine isopodes linking reproductive isolation to sex chromosomes and chromosomal fissions / fusions / translocations www.biorxiv.org/content/10.1...

Sex chromosomes and chromosomal rearrangements are key to behavioural sexual isolation in Jaera albifrons marine isopods
The lack of sexual attraction between individuals from different populations is a direct barrier to gene flow between these populations. Here we focus on the evolution of this class of isolating mecha...
