Freshwater salinization poses global challenges for aquatic organisms inhabiting urban streams, impacting their physiology and ecology. However, current salinization research predominantly focuses on ... salinity (Euryhalinity) [ 36 ]. Even landlocked freshwater populations of stickleback, which have been separated from the marine environment for thousands of years, possess the osmoregulatory machinery
