Role of reliability factors in adaptation of natural populations of hydrobionts to antropogenic effect

Investigation of antropogenic effect on water ecosystems and creation of evaluation techniques of their safety become the central problem in biology. Genetic processes in hydrobiout populations at their adaptation to the effect of heavy metals and radiation are studied. Antropogenic effect is shown to cause the increase of mutation and recombination modification and selection of stable genotypes and elimination of nonviable ones. These processes provide for population adaptation to new ecological conditions and increase their stability and safety
