Evolutionary biologist at CNRS focused on ecotype diversification and speciation across intertidal ecological gradients.

We are offering a fully funded two-year postdoctoral position focused on sex chromosome evolution and speciation in the *Jaera albifrons* species complex. Please find the advertisement attached. We welcome applications from interested candidates. Join us :-)

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...

Inversions support both parallel and location-specific adaptations in snail ecotypes

Replicated hybrid zones between ecotypes established over within shore environmental gradients provide an opportunity to study the genomic architecture of barriers to gene flow. The marine snail Litto...

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

Short INDELs and SNPs as markers of evolutionary processes in hybrid zones

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

Our collection 🔍 phase was not a fiasco🎉! Thanks to many passionate collaborators🤝, we sampled more than a thousand snails from 23 sites and visited lovely places, labs, and colleagues♥️. We’re looking forward to the next steps and unveiling these 🌊🐚🐌 secrets! Updates here: rb.gy/givc52
