To the question of the relationship between the diversity index and the saprobity index in algae and invertebrates

Abstract

A description is given of the process of creating an empirical model of the functioning of aquatic ecosystems, its indicators, and the limits of the parameters related to progressive succession stages when considering the effects of pollution. In addition to the previously used data for autotrophs, the parameters of the diversity of consumers are included in the model. The overestimation of impact assessments based on the second trophic level is discussed. Based on the data of the private allotment of water bodies of Ukraine, a conclusion is drawn on the conformity of estimates regardless of the geographical location of water bodies and on the suitability of interpretations for water ecosystems of a wide ecological spectrum.
