Distinct bacterial and protist plankton diversity dynamics uncovered through DNA-based monitoring in the Baltic Sea area
Planktonic microorganisms in coastal waters form the base of food webs and biogeochemical cycles. The Baltic Sea area, with its pronounced environmental gradients, serves as a model coastal environmen...

The latest preprint in my PhD just went through a major internal revision. More focused and less confounded, it deserves re-introduction.
Highlight still the same: Bacteria are ecologically more sensitive to salinity than protists.

And just when you thought things were settling down, the enigmatic Asgard archaea have another surprise in store! Cell cycle/life cycle stage-specific internal compartments with almost no eukaryote-derived clues as to how they might function.
Beautiful tomography and microscopy - congrats all 🤩
