Herlemann, Daniel P R Delgado, Luis F Riedinger, David J Fernández-Juárez, Víctor Andersson, Anders F Pansch, Christian Riemann, Lasse Bengtsson, Mia M Gyraitė, Greta Kataržytė, Marija Kisand, Veljo Kube, Sandra Martin, Georg Piwosz, Kasia Rakowski, Marcin Labrenz, Matthias 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. Changes in salinity generally have a strong impact on the biota, especially at the salty divide between salinity 6 and 9. To better understand the impact of the salty divide on the interaction between Z. marina and the surrounding sediment and water microbiota, we investigated the effects of Z. marina meadows on the surrounding microbiota across a salinity range of 6-15 in the Baltic Sea during the summer using 16S and 18S rRNA gene amplicon sequencing. Salinity was the most important factor for structuring the microbiota within both water and sediment. The presence of Z. marina affected the composition of the bacterial and eukaryotic community and bacterial alpha diversity in the sediment. However, this effect was confined to alpha-mesohaline conditions (salinity 9-15). The impact of Z. marina below salinity 9 on water and sediment microbiota was insignificant. Increasing salinity was associated with a longer leaf length of Z. marina, causing an increased canopy height, which affects the sediment microbiota through reduced water velocity. Hence, we propose that the canopy effect may be the major predictor explaining Z. marina's interactions with the surrounding microbiota at salinity 9-15. These findings emphasize the importance of the physical effects of Z. marina meadow ecosystem services and have important implications for Z. marina management under brackish conditions in a changing climate. |
