Today at the @iec.cat , @matteoagazzi.bsky.social gave an update on our coral reference genomes project🪸, part or the @catbiogenoma.bsky.social. It was great to see what everyone is working on within the @catbiogenoma.bsky.social effort! #corals #genomes

[email protected] is officially a PhD student in our lab! Her thesis project will explore the evolutionary history of Suessiales and the origin of symbiosis in the group🦠 Welcome!!🥳 #protists #corals #symbiosis #protistsonsky

We had a great time last week at @same18-bcn.bsky.social in Barcelona!

Your students arrive in Curaçao earlier than you and say: We are bored. Can we do that extra diel cycle sampling that we talked about 🤔 ? Your only answer as a PI: Sure 😬 The outcome? Sleep-deprived students and an excellent work on the #coral holobiont rhythmicity 🪸🦠⏰ #symbiosis #microbiome

This effort was a 'tour de force' only made possible by my incredible lab @ambonacolta.bsky.social and @fonamental.bsky.social. Absolutely thrilled to get this part of my Ph.D. dissertation out, thank you everyone involved!

Lastly, we explored microbiome structure 🦠 through time. Broadly, the microbial composition is largely stable through time, with notable taxon-specific changes through day/night light cycles. During the day carbohydrate catabolizers show enrichment, while night hours feature methylotrophs.

Similar to the host, the symbiont Breviolum showed diel regulated transcription, although more subtle. Time-specific functions were recovered, showing metabolite transfer and nitrogen/carbohydrate metabolism through daytime, while cellular division and reorganization/turnover during the dark hours.

In the coral host, we observed dawn as a molecular surge in RNA metabolism 🧬, midday exhibits high phosphate regulation 🔋, dusk reflects lipid & amino acid metabolism ♻️, and midnight shows mRNA catabolism & mitochondrial reorganization 🗂️. Most striking, we recovered ~30% transcripts as rhythmic.

🚨New Preprint Alert🚨 P. strigosa, a reef-building coral shows tightly regulated transcriptional control over natural diel cycles. #CoralReefs #Symbiosky #bioinformatics #marinemicrobes #protistsonsky www.biorxiv.org/content/10.1...

9/ Bryozoans are key habitat-formers, yet often overlooked in climate research. Our work shows they’re at risk under future ocean conditions. 🌊 We need more long-term, multi-stressor studies in natural settings. Stay tuned for the ongoing HOLOCHANGE and MedAcidWarm projects!

8/ This is the first study to document long-term microbiome and skeletal responses to combined ocean acidification & warming in bryozoans in the wild. We reveal: ✅ Complex, species-specific strategies ⚠️ Signs of vulnerability under future ocean conditions

7/ What about long-term effects? We monitored Pentapora populations over 5 years: 📉 Bryozoan cover declined ☠️ Necrosis increased 🌡️ Warming & acidification together accelerated mortality

6/ But not all are good news... We also observed: 📉 Loss of key microbial genera ☠️Rise of opportunists & anaerobes These microbial shifts may signal early dysbiosis — an early warning of declining host health.

5/ 🦠 Microbial communities: We found species-specific core microbiomes, conserved across both pH conditions. This stability suggests potential acclimatization capacity in both species despite environmental stress.

4/ 🧱 Mineral & skeletal structure: The two species showed opposing strategies to low pH. 🦪 P. ottomuelleriana reduced Mg-calcite & zooid volume 🪸 M. truncata thickened its skeleton → Different energy trade-offs to maintain calcification under stress

3/ We focused on two species: 🦪 Pentapora ottomuelleriana (fast-growing, encrusting) 🪸 Myriapora truncata (slow-growing, erect) They naturally occur inside & outside a Mediterranean CO₂ vent. 🌋 We also used 3D micro-CT scans to visualize how their skeletons change.

2/ Why bryozoans? 🪸 They build reef-like structures 🌍 They're widespread + ecologically important 🦠 But largely understudied—especially their microbiomes! We studied them at a volcanic CO₂ vent & a control site in Ischia Island, a "time machine" for future oceans.

1/ Our new paper is out today in @commsbio.nature.com @natureportfolio.nature.com 🚨 🔗https://www.nature.com/articles/s42003-025-08524-8 We studied how two Mediterranean bryozoan species respond to ocean acidification & warming using a natural underwater CO₂ vent as a climate change lab. 🌊🧫 🧵⬇️

Has it lost its mind? Can it see or is it blind? Don’t worry — we’re not judging anyone. We’re just amazed by the protagonist of this week’s #MidweekMicrobe. Make some noise for a true Ironman: the euglenozoan Euglena mutabilis! 🤘 🦠 📷 Gerd Guenther

𝘈𝘱𝘰𝘴𝘵𝘪𝘤𝘩𝘰𝘤𝘺𝘴𝘵𝘪𝘴 is named for its host (𝘈𝘱𝘰𝘴𝘵𝘪𝘤𝘩𝘰𝘱𝘶𝘴 𝘫𝘢𝘱𝘰𝘯𝘪𝘤𝘶𝘴), while the species epithet 𝘨𝘶𝘥𝘦𝘵𝘢𝘮𝘢 draws from the Japanese pop icon Gudetama, a lazy egg, highlighting the parasite’s link to the ovaries. The name captures both ecological context and cultural ties to Japan 🇯🇵

🌊 𝘈𝘱𝘰𝘴𝘵𝘪𝘤𝘩𝘰𝘤𝘺𝘴𝘵𝘪𝘴 𝘨𝘶𝘥𝘦𝘵𝘢𝘮𝘢’s close relationship to these marine host–associated clades has interesting implications for apicoplast evolution, which we hope to explore further in the future ☀️
