An amazing six week field campaign to the Southern Indian Ocean and the Terres australes et antarctiques françaises as part of the OBS Austral MD249 and the Themisto team has come to an end. Fantastic sampling of krill for climate adaptation research and great new friends and colleagues!

We have 🐟 herring pre print! Our new study reveals that ancient gene flow between Pacific and Atlantic herring played a key role in helping Atlantic herring adapt to the brackish waters of the Baltic Sea. www.biorxiv.org/content/10.1...

Field work friends: recommend a dissection microscope that is suitable for field work focused on determining small invertebrate species! Needs good optics, portability and sturdiness. I have used Wild Heerbrugg M5A and M8 before, which are great but long in the tooth. Any modern alternatives?

@cemeb.bsky.social Our wonderful night and #CeMEB2025 conference dinner at venerable Gästrike-Hälsinge nation was perfected by an amazing performance Sånggripen, the ÖG nation choir.

And we're off! The #CLUPEA project, with researchers from Uppsala and Stockholm universities, has started! We will do advanced genetic research to understand the molecular mechanisms that enabled the herring to adapt to the Baltic Sea and that may be key for their resilience to climate change.

Such an exciting diversity and quality of presentations related to the evolution of vision and opsins at #ESEB2025! I regret we did not organize an associated symposium on these topics. To make up for it, please pop by my poster today (035) and we can have a mini symposium right here!

Tomorrow, on campuses across Europe, perplexed researchers will wonder, where did our evolutionary biologist colleagues go? Well it seems to me that we all went to #ESEB2025!

I am announcing an open PhD position involving bioinformatics, genomics and machine learning to work on functional prediction of adaptive genetic variation in krill and herring! www.uu.se/en/about-uu/... Going to #ESEB2025 @eseb.bsky.social ? Find me in poster session 1 for a chat!

How does a plankton-eating fish evolve into a fast-growing, fish-eating predator? 🐟🤔 We are excited to share our new study in Nature Communications and answer this question! 1/n
