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.

Glad to share our new paper in Nat Ecol Evol, where we present the world’s most accurate model for predicting bird occurrences.

www.nature.com/articles/s41...

Using digital twinning and HPC, we show how even participants without bird ID skills can contribute to real-time biodiversity forecasting.

Metsien terve ihmispelko pitää säilyttää: kaataa puut ja möyriä maa niiden alta 60 vuoden välein. Muuten BIODIVERSITEETTI pääsee valloilleen. Kääpä kasvaa käävällä ja elättää kaikenlaista öttiäistä, jotka taas elättävät kaikkea muuta joutavaa elonkirjoa, hömötiaiset ja kuukkelitkin hyppivät nenille!

Suomen Akatemian jättirahoituksen saanut tutkijayhteisö haluaa kääntää katseet suolle - huippuyksikkö aloitti jo työt Planeetan hiilestä noin kolmannes on sitoutuneena soihin. Ilmastonmuutoksesta on tähän asti keskusteltu paljon metsien ja merten kautta. On tullut suon vuoro.

YLE uutisoi 5 milj. € rahoituksen saaneen Suot, ilmastonmuutos ja ennallistaminen -huippuyksikön työn käynnistymisestä.

Merkittävä tunnustus ja mahdollisuus suomalaiselle suotutkimukselle.

70 tutkijan ryhmää johtaa prof. Eeva-Stiina Tuittila Itä-Suomen yliopistosta.
