#Paper_Alert! Did you ever wonder why there is such a large morphological diversity in #shell-bearing #amoebae and what is the #function of shells anyway? It was long assumed shells are for #defense, well let me try to convince you that their purpose is #attack! A thread🧵👇
Following up on my last post, here is a glimpse into the culture room, where our protists are now growing and awaiting exploration. Excited to see everything fully operational! As you see, there is still a lot of shelf space to fill - one step at a time. Now back to proposal writing 🫡 #protists

The molecular lab, culture and microscopy rooms, and bioinformatic server, are now fully set up! I’m very grateful for my new position 🎉 We’re already generating results and insights in Koblenz, and I’m looking forward to the years ahead! Now, I "just" need to get the proposals funded 🫡 #protists

In case anyone’s wondering how things are going in my new position at the University of Koblenz - I think this picture makes it pretty clear we’re in great spirits! 😄 Julia and I are out sampling #cyanobacteria and #protistsonsky on local lakes :)

New logo for my new workgroup :) Yes, it's abstract, but I have the feeling it draws attention #protistsonsky

A bit late to the #skyparty but I was really glad to co-chair our special symposium on protist traits at #ICOP2025 organized by #ISOP in Seoul 🇰🇷
Grateful for the inspiring talks, engaging discussions, and the chance to reconnect with old friends and colleagues from around the world.

Today is the last day of #ICOP-ISOP2025! It was a blast, I enjoyed it a lot, feel very motivated, met and talked with plenty of fellow scientists, but also regret I couldn't discuss with even more people! Until next time :) #protistsonsky

Here you will find a great overview of genomic tools and their application on protists. Figure 3 is crazy interesting for everybody who wonders about what kinds of protist genomes are available, their sizes and why there aren't more. Take a look! Glad I could contribute :)
Happy to have contributed to this great article: #Protist genomics: key to understanding eukaryotic evolution. Congrats Alexandra Schoenle et al. #ProtistsOnSky

Glissomonads (Cercozoa, Rhizaria) are always in for a surprise! Saprotrophic, sucking up bacteria lysate. Axenic culture! #ProtistsOnSky
First post on Bluesky!
Our paper on previously uncultured Group-TE Glissomonad protists has been published. Video teaser below.

Big thanks to #OpenAI and #ChatGPT -not for helping me write my manuscript, but for clearly writing one of the reviewer's entire review!😂 Never thought I’d get peer-reviewed by a Large Language Model with imposter syndrome. Some recommendations are hilarious😅 #protists #ProtistsOnSky #nonamedropping

Evidence for #recombination, and maybe #meiosis, in free-living #Rhizaria! I wish the results were clearer. As so often we raised more questions than we could answer :) If you are into #sex and the #meiosis-toolkit, this is an important read! #ProtistsOnSky link.springer.com/article/10.1...

Very proud to announce that my first (shared) doctoral student, Dr. Jule Freudenthal, finished her doctoral studies! 🎉 She did amazing work! I know my recent shift to a professorship is for certain parts due to her work. We both align very well which is why I am happy that she is now my postdoc :) 🎊

🧠🦠🚨 New preprint alert! We’ve built the first trait database for Amoebozoa, and showcase ecological insights and evolutionary patterns. If you're into protists, soil ecology, or functional biodiversity - this is for you! #ProtistsOnSky #MicroSky 🧵👇

🚨New preprint out! We show that Arcella spp., a shell-bearing amoeba, controls the abundance of the filamentous bacterium Ca. Microthrix parvicella, the main culprit behind sludge bulking in wastewater treatment plants. Interested in applicability of protists? Read along! #protistsonsky #microsky

I'm starting my research group in Koblenz on April 1st (no April Fools' joke!) and will soon advertise two postdoc positions in #protist #ecology and/or #genomics. If you're a (soon-to-be?) postdoc-level #protistologist looking for a job, get in touch! One position on wastewater, the other flexible!
