This Tuesday, we had a successful fieldwork day with sunny weather and an amazing autumn atmosphere in the forest. Thanks to Jim Zonneveld for his help, to the Marie Skłodowska-Curie Actions for funding & IBED at University of Amsterdam for hosting me. Hopefully, I can share some results soon. 🥳

1/4 I had a blast at the international conference of the IUSSI in Freiburg this week. 🥳😊 I've learned many new things 🐝🐜, met peers and friends, talked to a bunch of new people, chatted about science and non-scientific things, got ideas about future projects and collaborations, and had also too ...

Still 31 °C (ca 88 ° Fahrenheit) at 9 pm in Amsterdam 🇳🇱. Granted, it is 7 to 8 degrees cooler than it was during the day and still cooler than in other major European cities, but still 🥵 We need to increase our actions against the climate crisis!

After a quite stressful morning (glitch in the camera, and I needed to be at uni earlier than planned to fix it), I am having a coffee now on the balcony. ☕☀️

A few days late, but we started field work in the Netherlands this week. Using red wood ants, we assess phenotypic plasticity of stress responses over the season using ants collected in the field and their acclimation to warmer climates in the lab. @uva.nl #marie-skladowska-curie-actions #msca

A big shout out to my amazing collaborators in this project, Patrick Heidbreder, Marjolein Bruijning, Patrick G. Meirmans, Sean Stankowski, and especially to Jonna Kulmuni ☺️🎉 Please share widely. 😃 @biorxiv-evobio.bsky.social #insects #ants #hybrids #climatechange #genomics #expansion

(3) Hybrids have also expanded 200 km northwards coinciding with the expansion of climatic conditions suitable for hybrids. Our results suggest that hybrids perform better under warming climates than their cold-adapted parent, and that recent climatic changes can lead to range expansion of hybrids.

(2) Hybrids have a higher genomic diversity & are active earlier in the season than its cold-adapted parent. Further, hybrid offspring emerge earlier in the season. Hybrids also withstand acute heat better than F. aquilonia. These results suggest a competitive advantage of hybrids over F. aquilonia.

At the moment, I am mainly doing fieldwork. Below, I share some impressions from fieldwork across various European countries

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

Last day of #eseb2025 will kick off in a few moments with the plenary talk by Prof. Johanna Mappes from @helsinki.fi "Signals of Survival: The Genetics and Ecology of Looking Dangerous"

Are you interested in ants 🐜 and/or hybridisation 🧬 and/or the impact of climate change on them? Then come to my talk this afternoon at 15:15, room 120-121 in S30 - Genomic insights into evolutionary adaptation and species movements in a changing climate.

#ESEB2025 just started in Barcelona. I am looking forward to many interesting talks and research, to meeting friends and connecting with new people. 🤗

Every day, I read to many bad news. I now decised to post something postive here every (other) day. I came across this beautiful meadow with daffodils and cherry blossoms last Saturday.
