Biogeocenology is the science dealing with interrelated and interacting complexes of living and inert nature (biogeocenosis) and their planetary aggregate (the biogeosphere). The term “biogeocenology” arose in geobotany but has subsequently developed as a common subject of biological and geographical sciences, reflecting the interdisciplinary level of the study of living nature .

The founder of biogeocenology was V. N. Sukachev (Photo1). In a number of works beginning in 1940 he defined the basic concepts of biogeocenology, its theoretical and practical tasks, its ties with other sciences, and the program and direction of research.
An important role in the development of modern biogeocenology was played by the works of the Russian scientists V. V. Dokuchaev, G. F. Morozov, and R. I. Abolin, who established the idea of the interconnected quality of the phenomena of nature, and by V. I. Vernadsky, who discovered the enormous planetary significance of organisms (living matter) (Photo 2-3) .

The questions under investigation in biogeocenology include research on the structure, properties, and functions of the components of the biogeocenosis and the transcription of the mechanism of their relationships; study of the flows of matter and energy in them, as well as the proportion and form of the participation of their components in the material and energy metabolism of the entire complex, and particularly in its biological productivity; study of the transformation by some components of the states, properties, and functioning of other components; determination of their role in the change and dynamics of the biogeocenosis; determination of the reaction of the components and the biogeocenosis as a whole to spontaneous changes and the economic activities of man; study of the stability of biogeocenosis and their regulatory mechanisms; and research on the relationships and interactions both between adjacent biogeocenosis and between the more remote ones, which provide the unity of the biogeosphere and its major parts.
These problems can be solved only with the participation of a broad range of specialists (botanists, zoologists, physiologists, microbiologists, soil scientists, climatologists, biochemists, and others) in research. These problems require extended periods of research, the use of experimentation (both under natural conditions and on models), the extensive application of quantitative methods of study, and the use of mathematical analysis and statistical processing of the data.
A successful solution to the problems of biogeocenology determines the possible accuracy of the prediction of the consequences of man’s interference in the course of natural processes, the possibility of directed regulation of the relationships and interactions of the components in the biogeocenosis in order to obtain the greatest and most generally beneficial economic effect (chiefly a rise in biological productivity), and the choice of ways for the economic use of the material and energy resources of the biogeosphere and its parts. The significance of biogeocenology is particularly great for forestry and agricultural practice. It is also of high methodological significance for the study of man’s environment on the earth and for space science, the protection of industrial articles, food products, and feed from damage by the biological components of the biosphere, the conservation of nature, and so on. Biogeocenology is closely related to landscape science, soil science, climatology, biocenology, microbiology, and biogeochemistry .

Objectivity of information
Biogeocenosis is an interrelated complex of living and inert components associated with each other by material and energy exchange; one of the most complex systems in nature.
Among the living components of the biogeocenosis are autotrophic organisms (photosynthesizing green plants and chemosynthesizing microorganisms) and heterotrophic organisms (animals, fungi, many bacteria, and viruses), and among the inert components are the atmosphere layer around the earth, with its gas and thermal resources and solar energy; and the soil, with its water and mineral resources and, in part, the weathering crust (water in the case of an aquatic biogeocenosis).
Each biogeocenosis maintains both uniformity (homogeneous, or more often mosaically homogeneous) of the composition and structure of its components and the character of the material and energy exchange between them.
The higher and lower green plants, which provide the basic mass of living matter, play a particularly important role in biogeocenosis. They produce the primary organic materials – the matter and energy that are used by the plants themselves and are transmitted along food chains to all heterotrophic organisms.
The role of chemotrophic microorganisms in the biogeocenosis is less significant. In terms of the specific features of their activities, heterotrophs in a biogeocenosis can be divided into consumers, which transform and partially break down the organic matter of living organisms, and decomposers or destroyers (fungi, bacteria), which decompose compound organic substances in dead organisms or their parts to simple mineral compounds.
In the functioning of a biogeocenosis, a great role is played by soil organisms such as saprophages, which feed on the organic remains of dead plants; and also soil microorganisms (fungi and bacteria), which decompose and mineralize these remains. To a significant degree, the structure of the soil, the formation of humus, the content of nitrogen in the soil, the conversion of a number of mineral substances, and many other soil properties depend upon their activity.
Without the heterotrophs, the completion of the biological circulation of matter, the existence of autotrophs, and the biogeocenosis itself would not be possible. The inert components of the biogeocenosis serve as a source of energy and primary materials (gases, water, and minerals).
The boundaries of a biogeocenosis can be traced from many of its components, but more often they coincide with the boundaries of the plant communities (phytocenosis). The mass of the biogeocenosis is not homogeneous either in terms of composition or the state of its components or in terms of the conditions and results of their biogeocenotic activity. This mass is differentiated into the aboveground, underground, and underwater parts which in turn are divided into elementary vertical structures—biogeohorizons, which are very specific in terms of composition, structure, and the state of the living and inert components.
The concept of a biogeocenosis was introduced by V. N. Sukachev (1940). This was the logical development of the ideas of the Russian scientists V. V. Dokuchaev, G. F. Morozov, G. N. Vysotsky, and others concerning the relationships of living and inert bodies of nature, as well as the ideas of V. I. Vernadsky concerning the planetary role of living organisms.
According to V. N. Sukachev, a biogeocenosis is close to the ecosystem of the English phytocenologist A. Tansley but differs by the definition of its content .

Biogeocenology is a scientific discipline that explores the structure and functioning of ecosystems, industry knowledge at the interface of biology (ecology) and geography. Biogeocenology grew out of geobotany, but subsequently developed at the junction of biological and geographical Sciences, reflecting the integrated study of living nature. Every year the relevance of the biogeocenotic increases due to rapidly changing environmental conditions, increased anthropogenic factor and the need to use a scientific approach in the organization of environmental activities.
