Genetic variability of charophyte algae in the Baltic Sea area
Abstract The Baltic Sea, a young habitat in geological terms, is characterised by strong climatic and salinity gradients that determine species distribution and trigger adaptation processes. The aim here was to test the hypothesis that Baltic Sea charophytes which originate from large freshwater pop...
