I will have a look into that. Thanks.

Thanks for the input. I will have a look into this as it seems to be the most flexible and low budget option!

Thanks, that may also work.

That is a great idea, thanks

Thanks. I was thinking about them. They are slightly too expensive for the project, I fear.

For a project, I want to film ants 🐜 each hour over several days, but only for about ten seconds. I would want to watch the videos later on.
Now I need your help BlueSky community: Is there any setup/blueprint that we could use to build it ourselves or is there a company with low-budget solutions?

(3) ... highlighting how sociality and haplodiploidy may influence speciation. Although key drivers of diversification have been examined, important gaps remain in understanding reproductive isolating mechanisms.

(2) ... behaviour, and genomics, many studies do not explicitly link their findings to broader theories of speciation & reproductive isolation.
In this review, we integrate microevolutionary studies of reproductive isolation & hybridisation with macroevolutionary research on ant diversification, ...

Ants are ecologically diverse and abundant organisms with strong potential to advance the study of speciation. Despite extensive research on their taxonomy, ...

(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...

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

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. 🤗
