“Biospherics” approach for studies of natural and artificial ecosystems Original Research Article

The main unifying feature of natural and artificial ecosystems is their biotic turnover (cycling) of substances which is induced with energy fluxes. A new integrating scientific discipline – Biospherics – studies biotic cycles (both in experiments and in mathematical models) of different degree of closure and complexity. By its origin, Biospherics is to be connected with extensive studies of Biosphere by Russian academician Vladimir Vernadsky. He developed and used “empirical generalizations” based on innumerous observations, comparisons and reflections. His “bio-geo-chemical principles” of Biosphere and ecosystems development have more qualitative than quantitative nature. Quantitative criteria to evaluate the efficiency of natural and artificial ecosystems are to take into account energy fluxes and their use in ecosystems of different types. At least, three of them are of value for estimation of natural and artificial ecosystems’ functional activities. Energy principle of extensive development (EPED), energy principle of intensive development (EPID) and main universal (generalized) criterion (MUC). The last criterion (Principle) characterizes the specific cycling rate of limiting chemical elements in multi-organism systems, developing under external energy fluxes. Its value can be a quantitative measure of effectiveness for every ecosystem functioning, including our global Biosphere. Different examples of these (above-mentioned) integrated criteria actions are presented and analyzed in the paper.
