Robust and accurate Bayesian inference of genome-wide genealogies for hundreds of genomes - Nature Genetics SINGER is a method for creating ancestral recombination graphs to understand the genealogical history of genomes. The method has increased speed, and thus scalability, without sacrificing accuracy.

SINGER, our ARG inference method, is finally published and freely available online:

It was a long journey – 16 months from initial submission to acceptance. Is it just me, or has peer review gotten more arduous lately? 4+ rounds of review isn't so unusual these days...

#ornithology

Why do males and females often differ in traits?
The expected answer: selection.
But our new paper in GENETICS shows that genetic drift alone can generate sexual dimorphism — even when male & female optima are the same

Super cool Fede! Felicidades!

I gave a symposium talk at the European Society for Evolutionary Biology 2025 (#eseb2025) meeting last week and this was my title slide showcasing how I was speaking as an independent scientist because @dalhousieu.bsky.social @dalhousie.bsky.social has locked us out.

Interested in eukaryotic algal evolution, metagenomics, new plastid diversity, and more? Check out my poster (P175) today at #eseb2025 ! #protistsonsky

If you're at #ESEB2025 drop by my poster today and let's chat about Birds-of-Paradise and their potential ring-like speciation history!

MEME alumni (www.evobio.eu) at #ESEB2025! We span so many generations now, from the first cohort (graduated in 2012) to those who are still studying, with master students, PhD students, postdocs, and PIs among us! So happy to get together in every ESEB 🤩

Sex-biased Migration and Demographic History of the Big European Firefly Lampyris noctiluca Abstract. Differential dispersion between the sexes can impact the colonization process and demographic history of a species. Here, we explored the demogra

This work shows the first overview on the population genetics and demographic history of the big European firefly, **Lampyris noctiluca**. Feeling very happy this work is out :) academic.oup.com/mbe/article/...

Is there an independent role of epigenetic variation in speciation? We looked for answers in the crow hybrid zone.
In brief: DNA seems to be in the driving seat.

Congrats Justin! This was a long journey.

Reconstructing NOD-like receptor alleles with high internal conservation in Podospora anserina using long-read sequencing NOD-like receptors (NLRs) are intracellular immune receptors that detect pathogen-associated cues and trigger defence mechanisms, including regulated cell death. In filamentous fungi, some NLRs mediat...

Absolutely stunning new preprint on centromere mutation from ‪@labschneeberger.bsky.social‬ @plantevolution.bsky.social ‪@jurriaanton.bsky.social‬ @lisasmith @plantylisasmith.bsky.social‬ & colleagues

Awesome new work from @labschneeberger.bsky.social (with a small contribution from the Weigel lab). Experimentally observed mutational patterns in centromeres underpin a model that recapitulates intra-specific centromere divergence!
