[Evolutionary conditioning of response to changes in ionic composition of water in hydrobionts: an example of freshwater zooplankton].
The situation in Karelian water bodies polluted with mining waste has been analyzed. As a result of technogenic wastewater discharge, the total ion content in lake waters has increased tens of times, and the concentration of potassium ions (the main component of wastewater), hundreds of times. Pollution tolerance of hydrobiont populations depends on the historically developed adaptation potential of species. The lowest tolerance to mineral pollution is characteristic of crustaceans representing mesolimnic families Polyphemidae, Sididae, Leptodoridae, Holopedidae, Diaptomidae, and Temoridae. Representatives of paleolimnic cristacean families Daphniidae, Bosminidae, and Cycopidae as well rotifer (Rotatoria) species of freshwater origin are highly tolerant of changes in the ionic composition of water.
