Microflora Danica: What can you learn from collecting and sequencing 10,000+ samples from a single country? Check out our new paper in @nature.com to find out. Incredible work led by Caitlin Singleton, Thomas B. N. Jensen, and Mads Albertsen from @aau.dk. 🦠🧫🧬

The Microflora Danica atlas of Danish environmental microbiomes - Nature
Microflora Danica—an atlas of Danish environmental microbiomes—reveals that although human-disturbed habitats have high alpha diversity, species reoccur, revealing hidden homogeneity.

Those interested in performing maximum likelihood phylogenomic analysis on data sets made up of eukaryotic nuclear genes using site heterogeneous mixture models like C60, I suggest you use the ELM model in IQ-TREE instead of the LG model /1

Aha, I realized that I forgot to add #ProtistsOnSky and #SymbioSky to this thread highlighting our recent respiratory endosymbiont paper.
Respiratory endosymbionts, that allow their ciliate hosts to breathe nitrate instead of (or in addition to) oxygen are frequent members of the wastewater microbiome. 🦠 🖥️🧬
Great to see this work by @louison-nicolas.bsky.social published in ISME coummuncations!

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).

Are you very busy but still want to learn what Aphelids are and why they are important to understand the evolution of Fungi?

Amazing several millimeters diameter single* celled acantharian. It is huge.
*presumably it is multi-nucleated and has hundreds of symbionts, but still! Way bigger than the ones I see locally. Only one set of spikes!

This is what I’m really here for :) These are the radiolarians we have been finding. Chock full of photosynthetic symbionts in a very interesting pattern- but no idea on the species. Doing some oxygen experiments and will sequence! #oceanography #zooplankton #christmasatsea ❤️🌊 #microsky

Excited to share the lab's 1rst preprint! Rapid high-res immunofluorescence is now possible in cultured & environmental diatoms thanks to 4-fold expansion microscopy. A step-change for comparative cell biology in one of the most important phytoplankton groups on the planet 🥳

This paper was much needed to highlight again the fact that protists make (almost) all main branches of the eukaryote tree of life, yet they continue to be dramatically understudied. Genomics is one example of this. Cite it!!! #protistsonsky

Looking for a postdoc on bacterial-insect symbiosis, combining evolution and molecular mechanisms? I'll have one open in my lab starting Sept 2025. If interested contact me (or find me at the GRC on Animal-microbe symbiosis if you'll be there). #SymbioSky

fourth and final chapter of my PhD is out! 🚨 We used single cell metabarcode sequencing to describe the diversity of organisms associated with polycystine radiolarians near Bermuda. we found that polycystines associate with a really wide diversity of phytoplankton, compared to other radiolarians! 🤩
