MicroSEA (Microbial Sea Eukaryotes) course is a one-week, field-based summer school to train early-career researchers in the diversity, ecology, and single-cell biology of marine protists. MicroSEA course integrates lectures, field sampling, and lab-based practicals in advanced techniques, such as flow cytometry, microscopy, culturing, and molecular analysis. The main objectives of MicroSEA course are: Fostering a deep understanding of marine protist diversity, ecology and biology; Providing hands-on training in advanced single-cell methods that are not commonly available in university programs; Building participants' confidence in designing and conducting research projects from field to data analysis; Promoting international collaborations and peer networking among students and speakers/trainers. The course will take place at the Station Biologique de Roscoff - SBR (France) - 7th to 12th of June, 2026 (arrival on the 6th, departure on the 13th). 20 participants will be selected, including 10 from EuroMarine member institutes. https://opbc.sciencesconf.org/

New preprint out! Using ~75k environmental OTUs + 77 fossil calibrations, we reconstructed a Proterozoic timeline of eukaryote evolution. Our results show crown eukaryotes were already diversifying >1.6 Ga, long before the first undisputed fossils (~1.05 Ga).

From short to long reads: enhanced protist diversity profiling via Nanopore metabarcoding In the last decades, environmental metabarcoding has revolutionised biodiversity research, particularly for microbial organisms such as protists, enabling large-scale assessments of diversity and ecol...

Researchers present the BaNaNA (Barcoding Nanopore Neat Annotator) pipeline and display the effectiveness of long-read Nanopore sequencing for protist biodiversity, ecology and evolution research.

Thank you so much to the amazing LoRe crew for giving me this wonderful opportunity ! It’s been a great time spent chatting together and an honor to get this series of podcasts started 🤩🙏. #protistonsky

Despite 150+ years of Radiolaria diversity research, we have just scratched the surface. Nearly half of Radiolaria diversity might be naked hiding in plain sight! We unveiled the diversity and evolution of Radiolaria beyond "the stars of the ocean"

Congratulations Miguel !!

Extant diversity, biogeography, and evolutionary history of Radiolaria Sandin et al. reveal a vast, overlooked molecular diversity of Radiolaria, likely skeleton-less, contrasting the traditional view of their star-shaped skeleton. Such comprehensive Radiolaria diversity...

Congrats @sandinmm.bsky.social et al, very nice paper: www.cell.com/current-biol... #protistsonsky

Why do some planktonic protists develop a gelatinous matrix? We suggest that this original adaptation is a strategy to cope with ocean oligotrophy: doi.org/10.1111/1462...
Led by @n-llopis-m.bsky.social, and thanks to all co-authors, I'm very happy to finally see it out!

Congratulations Camille ! All the best for the next adventures

Stoked about this manuscript, many years in the making. We present an original resource of ~700 highly curated plastid MAGs of marine pelagic algae. Among these we found a novel deep branching group of plastid genomes; we informally call them leptophytes

La Station Biologique de Roscoff vous souhaite une très belle année 2025 !
Pour cette Année de la Mer, la préservation, la recherche et le partage des connaissances sur l'Océan seront au coeur de nos engagements.

Next Monday 13 we have the 6th session of The Life of Retaria Seminar Series!
Join us at 08h00 (CET) and discover symbiosis in these wonderful protists with Caroline Juery and @filiphusnik.bsky.social
