Technoecosystem of the cooling pond of the South Ukrainian Nuclear Power Plant: group dynamics and transformation

The results of long-term complex hydrobiological studies of the cooling pond of the South Ukrainian Nuclear Power Plant (SU NPP) are presented. The abundance of zoo- and phytoplankton increased until 1984–1985, and then in the summer of 1986, against a background of extremely high temperatures in th...
