High alkalinity reduces growth of the invasive microalga Gonyostomum semen (Raphidophyceae)
The unicellular Gonyostomum semen (class Raphidophyceae) is an invasive microalga which can dominate phytoplankton communities during blooms, with economic and ecological consequences. Its abundance in European freshwaters has been mainly explained by water temperature, colour, and acidity. While low pH and brown colour are common features of lakes containing the species, it has also been found in
