Abstract:
We assessed the seasonality of bacterial settlement pressure, defense against microsettlers and concentrations of a previously identified defense compound, Rosmarinic acid, on surfaces of the eelgrass Zostera marina, sampled monthly at four plots in the Kiel Fjord (SW Baltic Sea). Water temperature, salinity, nutrient concentrations in water and light intensity were also measured, as well as photosynthetically active radiation.
