Pakhomov O. Biogeocenotic role of mammals in soil forming processes in steppe forest of Ukraine

The object of research are mammals and them environment formiing activity in conditions of steppe woods of Pridneprovje. The purpose of research are to establish a role of mammals in the processes of soiil formation, in formation of homeostasis mechanisms and formation of processes selfcleaning of wood systems. The methods of research are comparative, direct calculation, variational statistics. In the work the experimental data are correlated, regularities of forming environment as a result of mammals activity in transformation of physico-chemical and biological soil regimes are determined. It is shown the role of various functional manifestation of mammals in soil processes, in forming mechanisms of soil selfcleaning from technogenic pollution and in systems optimisation. Measures on using environment forming activity of mammals in biotechnological methods of biodiversity conservation, environmental protection and construction of soils and forests under conditions of steppe zone and technogenic landsc apes hane been developed. Main results of the work are introduced in nature protection and environmental organisation, scientific and educational processes.
