What a morning view in Amsterdam

I am re-posting this, in case you have missed it 😀

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. 😃

(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.

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...

(1) So happy to share our recent work on Finish wood ants 🐜🧬🥳

Funded PhD position available 🎉 Come and work with me in Helsinki to uncover the pathways producing colourful tiger moth wings. Lots of options for genomics, CRISPR, fieldwork, behaviour experiments… Email with questions! jobs.helsinki.fi/job/Helsinki...

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

One mother for two species via obligate cross-species cloning in ants - Nature In a case of obligate cross-species cloning, female ants of Messor ibericus need to clone males of Messor structor to obtain sperm for producing the worker caste, resulting in males from the same moth...

You may have missed this #ant poster at #ESEB2025, but be sure not to miss the article just published in #openacess in @nature.com: www.nature.com/articles/s41...

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"

Last #eseb2025 poster session has just started 🎊

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.

Are you interested in the impact of climate change on hybrids, come to my talk on Thursday, 21.08, at 15:15 (S30), meeting room 120-121.

"Implications of expanding hybrid wood ant populations on heat tolerance and phenology under climate change"

Thanks to #MSCA and #EU for funding my project. 🎊

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

Sunset behind the trees

Sunrise in Utrecht

What a beautiful morning in Amsterdam it was

A picture of the kingsday (Koningsdag) festivities (the birthday of the king) celebrated on Saturday in the Netherlands

Spring meadow in Austria with spring flower Crocus

Spring is now also approaching at higher elevations in Austria ☀️

Spring meadow with daffodils. in the back of the picurre, there are cherry trees with cherrry blossoms agains a blue sky.

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.

Photo of a small crab from NOAA’s social media. It’s covered in spikes

Just making sure that everyone is aware of this crab that NOAA scientists found

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!

36th Entomologendag 2024 from the Dutch Entomological Society in Ede just started.

Diagram showing how tree species diversity can influence understory plants through changes in microclimate which in turn affects phenology and nectar and pollen quantity and quality. This may affect pollinator visits and plant fitness

📣 Fully funded PhD project supervised by me & @philstevenson.bsky.social within @treesdla.bsky.social on effects of forest diversity on floral reward production for pollinators. Nice mix of fieldwork in Finland & pollen and nectar chemistry 🐝🌼🌳🌲 🧪🌍 Apply by 20 Jan www.trees-dla.ac.uk/projects/eff...

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.
