We have studied changes in flora, humus content, peroxidase activity and polyphenoloxidase in ordinary black soils in natural succession of different-age deposits. We have also selected stage successions in uneven deposits
Negative impact of oil on biological properties of soils right after pollution is shown in the article. Eventually, there is their restoration. However, even in some years after pollution, the biological properties of soils aren't restored completely
Hydrothermal conditions have a significant effect on catalase activity of soils of the South of Russia. The linear dependence of catalase activity in the upper horizons soils from average annual rainfall, aridity index of de Martonne and the coefficient of moisture of Mezentseva. In terms of catalase activity of the
entire humus profile we revealed that the maximum activity has leached black soil, located in the medial climate conditions of the South of Russia
Large agricultural load on the steppe landscapes
leads to the transformation of ecosystems and effect
on all their components. Transformation of lands into
laylands leads to a gradual restoration of
anthropogenically disturbed steppe ecosystems.
Studies that focus on the research of comprehensive
processes in the territory of laylands are extremely
relevant today. Herpetobiont fauna is one of the
important characteristics of ecology and biology of
soils. Herpetobiont Coleoptera can serve as
indicators in the study of processes occurring in
postagrogenic soils.The article presents the results of
the study of changes in mesofauna, composition and
structure of complexes of the gerpetobiont
Coleoptera of ordinary black soils in natural
succession series of different-age laylands. We also
evaluated the degree of faunistic similarity of plots
of laylands and allocated dominant species.
Carabidae and Tenebrionidae are the basis of
complex Coleoptera in the investigated laylands. The
article shows that such indicators as the number of
individuals, species, families of beetles and their
dynamic density are depended on the age of the
layland. In addition, the indices of biodiversity
(Margalef and Shannon) and dominance (Simpson)
are also connected with the age of plots of laylands
