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. 🌊🧫

Morphology wise, P. noduliferae has an overlall flattened shape, transverse surface folds and a flagellar apparatus, which is located at the apical end of the cell and contains two flagella (anterior and posterior) that move in a whip-like motion.

The Platyproteum genus had been formerly assigned to the Apicomplexa, but was later demostrated by Mathur and colleagues that it actually branched off from the base of the chrompodellid taxa and apicomplexan clade. P. noduliferae is sister to P. vivax (Yokouchi et al 2022).

👏🏼👏🏼👏🏼 Lucky to have @fonamental.bsky.social as our PI!!😊
It is an honor to receive the #ISOP Hutner Award to a researcher within 15 years of his PhD who has made outstanding contributions in protistology 😊

I would like to thank my mentors (Ramon Massana, @multicellgenome.bsky.social, @pjkeelinglab.bsky.social) and my past and present students 🙏

Last week we attended the Jornades de Biologia Evolutiva, organized by the @scb.iec.cat 🧫

@matteoagazzi.bsky.social and @rociomozo.bsky.social did a great job presenting their advances on their coral HMW and HiC data generation and Suessiales de novo transcriptomics projects🧬🤩

Keep it up folks!☺️

Hey you, hurry up! You're just in time for a trip to the Late Cretaceous🌍 🦖
Sea levels are high and dinosaurs rule the Earth… but we’re here for a different kind of dino.

This #MidweekMicrobe, meet the fossil dinoflagellate Desmocysta hadra!🦠 ⛏️

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 🇯🇵

🧬 rrn operon phylogeny revealed this parasite to be closely related to apicomplexans of marine fish 🐟 (ichthyocolids) and corals 🪸(corallicolids), while organelle phylogenetics hint at a closer relationship with Eleutheroschizon, an apicomplexan associated with a marine Polychaete 🪱

Eleutheroschizon duboscqi is a marine protococcidian that parasites the polychaete Scoloplos arminger🪱 . It grows epicellularly, enclosed in a two-membrane parasitophorous sac derived from the host cell, that ends in a protein-rich tail #Midweekmicrobe

What a week, huh? For those who missed it, the Iberian Peninsula experienced a power outage this Monday that lasted 12 hours!
Luckily for us, this #MidweekMicrobe brings in an expert in alternative energy generation: the foraminifera Hauerina diversa🌿 ☀️

🌟 Taken together, we suggest fireworms are a reservoir and potential vector for corallicolids, moving parasites between coral hosts via feces 🪱💩🪸. This deepens our understanding of coral reef host-parasite interactions and reveals exciting new corallicolid ecology!
