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.

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!

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

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

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.

🦠 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.

🧱 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

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.

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.

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.
