Community composition in lakes and reservoirs along a trophic gradient

Microbes show a recurrent structure in which a relatively small number of abundant bacteria coexist with the "rare" biosphere. Abundant taxa are dynamic over time and space and reactive to local conditions. Dispersal limitation could have a strong influence on the community composition. During a monitoring program in 2016 (April- September), we investigated the microbial community composition in four Croatian freshwater lakes with different origin and trophic status: Lake Visovac -mesotrophic karst lake located in the Krka National Park ; Lake Prošće - an oligo- to mesotrophic karst lake located in the Plitvice Lakes National Park ; Lake Jarun - a mesotrophic, anthropogenic lake formed 30 year ago in the city of Zagreb ; and Lake Sakadaš - an eutrophic floodplain lake in the Danubian valley of the Kopački Rit Nature Park. Lake Sakadaš showed the most even microbial community composition, with various Beta- and Gammaproteobacteria, Actinobacteria and Verrucomicrobia co- occurring. Microbial communities in Lakes Visovac and Jarun were strongly dominated by the actinobacterial genus Ca. Planktophila, a representative of the yet uncultivated acI lineage, frequently detected as the most numerous taxon among total freshwater bacterioplankton. Interestingly, Actinobacteria were not as dominant in Lake Prošće. Instead, various Comamonadaceae- and Burkolderiaceae- related Betaproteobacteria occurred in similar frequencies. Notably, stark shifts in the dominant community members were observed in Lake Prošće during our sampling, indicating a less stable microbial core community.
