Obiettivo The problem of estimating the state of the Earth's water resources and then managing them has global importance and urgently needs new, effective, and relatively inexpensive methodological approaches. In the World's ocean, the main biomass accretion is carried out by the microplankton (organisms This proposal focuses on studying the community structure, the biochemical characteristics and the energy flows of the different microplankton size categories under various ecological conditions, together with developing the concept and application of the heterotrophic-photoautotrophic (HP) index of the quality of the aquatic environment, measured by novel indices.Microplankton fractionation into size categories, achieved by using filters and nets, will be accompanied by its biochemical partition into heterotrophic and autotrophic parts. The size fractions ratio, which reveals the typical proportions of the biochemical components and the morphometric indices provides important information on the microplankton size structure and reflects the community response to environmental changes.Microscopy of autotrophic and heterotrophic parts of the community will support calculations of the HP index by biomass estimations and biochemical measurements; it will also help in the estimation of the levels of the diversity of the community species. Microcalorimetry of the microplankton size categories will provide complementary information on the processes of microbial interactions, and on the material and energy flows and fluxes dependent on the quality of the living environment.Comparative studies of the microplankton will develop generalized data data sets for the field of heterotrophic-photoautotrophic interaction in the lowest trophic part of the aquatic ecosystem. Such a triad of methods (microscopy, biochemistry, and microcalorimetry) for estimating the relative representations of the HP index will provide a more objective criterion of water environmental quality, giving a basis for forecasting the effects of change while warning of the need for countermeasures.Besides its fundamental importance to the world ocean, increasing the knowledge of microplankton size spectra has social significance and prospects for generating new approaches to control water quality in reservoirs.
