Salinity Negatively Impacts Protistan and Fungal Community Stability and Shapes Assembly Processes in Freshwater Ecosystems

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 5, October 2025.
We investigated the spatiotemporal and biogeographical patterns of protistan and fungal communities in the water column of two different lake systems in Croatia through almost 2 years. Salinity has a strong influence on both communities. ABSTRACT In freshwater lakes, protistan and fungal communities play crucial roles in the microbial loop as ...
