Gandzyura V. Biosystems productivity in toxic environment

In the thesis on the basis of methodology of the productive-energetic approach, the questions of biosystems (organisms, populations and communities) productivity under conditions of water environment pollution by heavy metals are considered for the first time. The following interconnections were revealed: the general laws of environment pollution influence by Cr6+, Ni2+, Pb2+on specific growth rate and accumulation of energy; efficiency of substance and energy transformation; size of the energy, saved in biomass, on unit of its accessible flow; ratio between sizes of the energy, saved in biomass, and level of breath. Is also shown, that even the insignificant increase of heavy metals' level in water causes essential fluctuations of meaning of all bioproductive parameters of biosystems. The general laws of these fluctuations were investigated at a different level of water pollution. The essential infringements of biosystems' energetic balance structure and phosphorus balance in toxic environment, infringements of matter-energetic processes in conditions of heavy metals environment pollution were revealed. It is offered the new method of ecosystems classification with a different pollution level
