(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

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...

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. 🎊
