Low impact of Zostera marina meadows on sediment and water microbiota under brackish conditions.

Background: Zostera marina is an important ecosystem engineer influencing shallow water environments and possibly shaping the microbiota in surrounding sediments and water. Z. marina is typically found in marine systems, but it can also proliferate under brackish conditions.

Temperature, sediment resuspension, and salinity drive the prevalence of in the coastal Baltic Sea.

Unlabelled: The number of -related infections in humans, e.g., by , has increased along the coasts of the Baltic Sea.
