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...

(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

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...

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...

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. 🎊

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.

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

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!
