How single-cell genomics is unmasking the hidden diversity of protists From giant kelp forests to the microscopic parasites in a single drop of water, protists represent the vast bulk of eukaryotic phylogenetic diversity.

From working on the Darwin #TreeofLife project to improving isolation and #sequencing methods, Dr Sally Warring is studying the diversity of #protists from natural environments to generate large-scale data for lineages underrepresented in the tree of life.

Huge news ๐ŸŒ๐Ÿงฌ
The Protist 10,000 Genomes Project is joining the Earth BioGenome Project.
Protists may represent the majority of eukaryotic diversity โ€” yet only a tiny fraction have reference genomes.
Time to change that. ๐Ÿš€โœจ

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.

Weltmeere: Hitzewellen in den Ozeanen Die Meere erwรคrmen sich immer schneller, Nord- und Ostsee ganz besonders. Das geht aus dem Statusbericht des Copernicus Marine Service hervor.

Die Meere heizen sich auf, verlieren Sauerstoff und versauern, der Meeresspiegel steigt, die Meeresรถkosysteme sind immer stรคrker unter Druck.
Wir leben auf einem Ozeanplaneten, und was mit unseren Meeren geschieht, wirkt sich bereits auf uns an Land aus.
