Основы биологической продуктивности Черного моря

The book is a comprehensive summary of all the data obtained by Soviet, Bulgarian Rumanian and other scientists who were engaged in studying biology and productivity of the Black Sea. The description of the sea ecosystem biological elements is preceded by three chapters dealing with characteristics of hydrological, optical and hydrochemical conditions in the sea. The following sections are devoted to a detailed consideration of phytoplankton, micro- and macrophytobenthos, their taxonomic composition, distribution, amount and their primary production. All the categories of consumers: zooplankton, zoobenthos, fishes as well as bacteria, both those inhabiting water strata and contained in the bottom ground, are discussed in the same way. A special chapter deals with ecological and physiological processes occurring in-animal organisms which determine the rates of energy flow and energy conversion in populations. In conclusion an attempt is made to develop a mathematical analogue of the Black Sea pelagic ecosystem.
