The paper uses CARD-FISH and sequencing to study microbial food web dynamics in the Baltic Sea, finding that omnivorous and predatory HNF dominate during phytoplankton blooms.

The paper investigates how freshwater ciliate communities respond to top-down and bottom-up manipulations in spring and summer, revealing season-specific trophic interactions and community shifts.

The paper investigates depth-dependent protist community dynamics in a freshwater reservoir during spring, revealing distinct community structures at different depths.
