I am pleased to share a preprint: Chilling injury to algal symbionts induces host starvation and metabolic reorganization in a temperate cnidarian www.biorxiv.org/content/10.6... #SymbioSky #MicroSky #internationslwomensday @agencerecherche.bsky.social @pure-ocean.bsky.social

How specific are heritable symbioses? And what can we learn from swapping obligate symbionts across host species? We address this in our latest, led by @inespons.bsky.social & in our collaboration w/ @microbiome.bsky.social 🦠🪲 Out today in @natcomms.nature.com! 1/n www.nature.com/articles/s41...

Antarctica isn’t one big tipping point. New research maps 18 separate ice basins, each with its own threshold. Some in West Antarctica may tip at just ~1–2C warming (i.e close to today’s levels). Cross the line, and you commit to m’s of sea-level rise over centuries www.nature.com/articles/s41...

🦠 Studying the biology and symbiotic relationships of holobionts living in extreme environments, such as the deep sea, is challenging. However, uncovering the strategies of these organisms to overcome harsh environmental constraints offers crucial insights into ecology and evolution of marine life.

New preprint! We explore how gutless marine worms and their bacterial symbionts use organosulfur compounds like DMSP and DMS - key molecules in marine sulfur cycling. Our results show that these compounds support carbon and energy metabolism in the Olavius algarvensis symbiosis.

New preprint: 🚀🧬 Starship in the genome of the lichen fungus Xanthoria. Discovery of giant transposons Starships challenged what we thought we knew about fungal genomes. But what about Starships in #lichen fungi? Let us present Tangerine! 🖥️ 🧪 🦠 🧫 #SymbioSky doi.org/10.1101/2025...

Fascinating hologenome study of a deep-sea black coral and their microbial symbionts 🪸

A couple of days left to submit your abstract for the upcoming EMBO/EMBL Symposium on the Molecular Basis of Symbiosis ! Great line up of speakers :) #ProtistsOnSky #SymbioSky

Here, we show that deep below, corals and feather stars don’t just share space – they share microbes. Endozoicomonadaceae + Nitrosopumilaceae inhabit both hosts in a “promiscuous” symbiosis that may fuel nitrogen cycling in the deep sea. doi.org/10.1186/s401... 🌊🪸🧪 #Bioinformatics 🧬💻 #SymbioSky

Happy weekend, symbiosis friends #SymbioSky #MicroSky

This got to me. Haunting and beautifully written. news.mongabay.com/2025/10/in-m...

Bleaching: more than just a coral problem.

🌟 New book chapter alert! 🪸 Coral reefs are threatened by climate change, especially by mass ‘bleaching’ events. Bleaching is caused by the loss of photosymbionts under stress, resulting in a white – ‘bleached’ - phenotype. link.springer.com/chapter/10.1... #SymbioSky #MicroSky

My first dive into Raman microscopy! 🔬 Our latest heat stress experiments on Aiptasia raised more questions than answers — until a few days of Raman spectroscopy with Dr. Peter Mojzeš at @charlesuni.cuni.cz helped connect the dots. Grateful for the collaboration and excited about what’s ahead!

I just returned from my holiday in Finland. While we were looking for bears, wolves and co, one of my personal favorites were these green-alga bearing freshwater sponges. Photosymbiosis is everywhere if you look close enough. Maybe it‘s time for some freshwater work at @hifmb.de?
