This is the product of great discussions 💬 and writing sessions 📝 with the amazing @mjamy.bsky.social & @lusantof.bsky.social 💪 With the fervent support of @fonamental.bsky.social, @daniel-vaulot.bsky.social and our other co-authors 🙏

Our roadmap includes: 1️⃣ Building a standardized ontology of protist traits and modalities 2️⃣ Populating a trait database following this ontology and using the existing literature 3️⃣ Integrating this database into the larger framework of tools routinely used in protistology Reach out if interested! 🫵

Hello there 🦋 Happy to share our piece "Towards a trait-based framework for protist ecology and evolution" in @cp-trendsmicrobiol.bsky.social Let's build a unified trait 📏 database to unlock transformative insights into protist 🔬 ecology 🌍 and evolution ⏳ ▶️ doi.org/10.1016/j.ti... #protistsonsky

New paper is out! We have studied the cute tiny Discocelia plataet sp. n. to obtain the first molecular data of the order Discocelida and clarify its cell structure. All this for a better understanding of the evolution of Cercozoa. onlinelibrary.wiley.com/doi/epdf/10....

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.

This is a great way to put an end to this academic year and start my vacation 😬 Thanks, Blanca, for leading this effort! 💪 We are having a lot of fun working together, so more #bryozoan #microbiome collabs will be happening soon 😊

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. 🌊🧫 🧵⬇️

That’s all for our acid-loving protist of the week. It truly exemplifies everything heavy metal is about: the power of friendship (or in other words, holobionts). Gather with us for the next #MidweekMicrobe, just like microbes in biofilms! lml 🦠 🍄 🧫

Notably, an isolate from an AMD site in Canada was found to boost its tolerance to low pH by associating with an antibiotic-producing fungus and an acidophilic bacterium — forming a truly heavy-metal holobiont known as the FAB (fungus, alga, bacterium) consortium.

Some of the mechanisms this alga uses to cope with heavy metals include supplementation of chlorophyll with other divalent cations (in place of Mg²⁺), and internal compartmentalization via precipitation or granule formation. 📷 Adapted from Brake et al.

In addition to being a bioindicator for AMD, E. mutabilis has been reported to grow in biofilms that trap contaminants and help precipitate them into iron-rich stromatolites, limiting their spread downstream. 📷 Adapted from Brake et al.

E. mutabilis is an acidophile that thrives in acid mine drainage (AMD), with optimal growth between pH 3.4 and 5.4. Like other euglenoids, this organism is photosynthetic and has a characteristic red eyespot.

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

We are looking for a new @thembauk.bsky.social Anne Warner Research Fellow (5 year post) to develop an independent research group in the area of cell and molecular biology of marine organisms here in #Plymouth 🔬🦠🧫🧬 mymba.mba.ac.uk/job-listing....
