Evidence for climate-mediated range expansion of hybrid wood ants
Climate change challenges many species. To persist, species can shift ranges, respond plastically, and adapt. Yet, these responses require variation - often limited in natural populations. While hybri...

A little late, but I still want to share the good news 🎊: I recently started my #MSCA postdoctoral fellowship. I will assess the impact of climate change on wood ants🐜 & their hybrids 🧬. My project is based at the Uni #Amsterdam with Jonna Kulmuni & @dickmerrill.bsky.social @lmumuenchen.bsky.social

Gestern habe ich Europas 1. Solar-Radweg besucht. Er steht in Freiburg, ist auf 300m mit 900 PV-Modulen überdacht, liefert Strom für rund 180 Menschen und schützt Radfahrer. Ein tolles Vorzeigeprojekt, dass Verkehrs- & Energiewende vereint. Ich hoffe, er wird vielen Kommunen zur Inspiration dienen❤️

🧪 I want to set up a teaching unit in a genetics course where we use sourdough starters to learn about evolution, sequencing, and diversity. Has anyone done that and can share experience, pitfalls, materials? The genetics undergrad course spans a full semester, we have a bit of time for culture!

I made a starter pack of speciation researchers. Please let me know if you or someone you know would like to be added. I am particularly sad that so far there are not many speciation researchers from the Global South represented.
