Who are fittest:☀️‘summer specialists’ that maximize growth season gains, or❄️‘winter specialists’ that minimize overwintering risk? We investigated this in temperate #lepidoptera, now out in Nature Communications Both work but cause different pop. dynamics. 🧵⬇️ doi.org/10.1038/s41467…

Curious how butterflies evolve across Europe? Me too!!! Let's join forces in sampling butterflies and moths across Europe, studying their evolution across latitudes and through seasons. Help start LepEU, the European Lepidopteran Population Genomics Consortia #LepEU 1/n

Hey BoB #LepEU curious people, let’s try a quick LepEU meeting at next coffee break, at 16:00 outside Room ZI to start talking face to face. Spread the word!!

We're continuing the Phenotypic Plasticity session with two very cool talks from Matthew Nielsen and Rachel Steward focusing on diapause in butterflies and how it is related to melanism and genetic diversity #BoB2023

Congratulations to Kalle Tunström for successfully nailing his thesis titled "Understanding evolutionary novelty through female-limited polymorphisms". The PhD defence will be on the 8th of September!

This is now out in Cell Reports! cell.com/cell-reports/f… It's accompanied by this very kind preview: cell.com/cell-reports/f… by Kronforst and Sheikh, which also looks at really cool work by Nishida et al on a convergently-evolved green liquid wing pigment (!?!?)

Looking for a postdoc, interested in butterfly population genomics? I'm looking for someone to write a grant with me, applying for a 2 year postdoc analyzing a wide assortment of genomic data from diverse species. Interested? email soon, I'm ready to write!

Congratulations to Alexandre Rêgo for successfully defending his thesis titled "Quo vadis? Insights into the determinants of evolutionary dynamics". Many thanks to the opponent Dmitri Petrov and the examining committee Martin Lind, Tanja Slotte and Jonas Warringer! Stelkens Lab

Please RT. I have an opportunity for a master project to study functional morphology of Odonata wing. Please see attached ad for details. If untested, please DM me your CV and a statement about your research interest and previous experience.

Our paper on alternative splicing in facultative diapause is out in Heredity rdcu.be/dxBV1. We build on previous results showing strong signatures of selection in plastically spliced genes. Much thanks to coauthors Peter Pruisscher Christopher Wheat and diapause expert Kevin Roberts

Genes diff. spliced in diapause have lower pi and pN/pS than other genes. Against predictions, the effect was stronger in univoltine (not plastic) than in multivoltine (plastic) populations of P. napi, suggesting negative/purifying selection maintains diapause splicing patterns

PSA, since I've now seen problems arising from this: As of Sept 2023, GATK no longer makes missing genotypes explicit in VCFs (i.e. "./." as in the VCF spec). Missing genotypes are instead coded as "0/0" with a DP=0 format field. See attached for examples.

Glad to share my last thesis chapter! We show that a 22nt micro-RNA controls melanic wing patterns in Lepidoptera biorxiv.org/content/10.110…

Delighted that our work on chromosome evolution in Lepidoptera is published today! ✨🦋

I’m so excited! My first-first author paper AND the first chapter of my PhD is now out in Current Biology : ‘Translocated wild birds are predisposed to learn songs of their ancestral population’: doi.org/10.1016/j.cub.… 1/📖 Read on for a short description:

Quantifying temperature’s effect on #diapause #termination requires fitting #TPCs to binary biological data. In our new paper, out now in #PNAS, we show how to do this, revealing the sequential nature of diapause termination and post-diapause development. doi.org/10.1073/pnas.2…

Supercool work on how butterflies terminate diapause! Potentially also explaining how they synchronize their emergance in spring! 🦋 🐛
