Abstract
inhabiting the Arctic Ocean whose evolutionary origin involved a freshwater to marine environmental transition. Crossing the salinity barrier is thought to rarely occur in bacterial evolution. However, given the ongoing freshening of the Arctic Ocean, our results suggest that these relative newcomers to the ocean microbiome increase in abundance and, therefore, ecological significance in a near-future Arctic Ocean.
