Closest relatives of Baltic Sea plankton are found in brackish North American waters

The first large-scale mapping of genomes of bacterial plankton in the Baltic Sea shows that the bacterias' closest relatives are not found in oceans or freshwater lakes, but in other brackish environments. The genomes may not yet answer where these plankton came from, but they will help scientists to better understand brackish, or briny, ecosystems.
