Eukaryotes in the Baltic Sea differ across environments and salinity gradients. a Counts of observed eukaryotic groups detected in the Baltic Sea across different environment. LMO samples were obtained at the Linnaeus Microbial Observatory near Öland, Sweden. Transect samples were obtained from 9 different geographic locations across the Baltic Sea. Redox samples were obtained from the redoxcline. Dark-colored bars indicate the number of samples from a given environment that contain at least one species belonging to the eukaryotic subgroup. Light-colored bars indicate the number of samples that do not contain a given eukaryotic subgroup. b The mean salinity of samples where eukaryotic species were detected. Bars indicate 1 standard deviation. Only species detected in 3 or more samples were included
