A study by MIT researchers explores how rising salinity caused by climate change could impact microbial ecosystems in rivers, estuaries, and coastal waters. As seawater intrudes into freshwater systems, the research finds that microbial diversity declines because faster-growing strains dominate. However, despite this loss of diversity, the overall growth rate and biomass production of the microbial communities remain largely unaffected. This has implications for the carbon cycle and decomposition processes in these environments. The study used samples from various salinity levels, including the Charles River, Boston Harbor, and a Massachusetts beach, and tested them under different salinity conditions.
