ABOUT THE SUBMERGED VEGETATION TRANSFORMATION DURING EUTROPHICATION AT THE SOUTH URAL SMALL LAKES
For the first time the role of the submerged high water vegetation under monitoring of two hypertrophic phytoplankton lakes has been considered in Chelyabinsk Region. It has been determined that water vegetation assemblages unification process occurred as a result of two initially different-type lakes biogenic saturation and decreasing water transparency. The two initially different-type lakes regarding morphometry, trophic nature, high water vegetation development level have been transformed to one phytoplankton type. The lakes trophic status corresponds to the hypertrophy level.
