Abstract
An increase in technogenic impact and the need to conserve biodiversity has set us the task of assessing the baseline biodiversity in mining areas. The aim of this work is to investigate the state of mesofauna of invertebrate animals in the litter and topsoil of typical biotopes of the Middle and Southern taiga. This study is the first in the Perm Krai. The vegetation characteristics of the survey sites are based on field geobotanical descriptions, soil sampling method was used to collect invertebrates, and soil properties were studied using conventional methods. Taxonomic diversity and population structure of soil invertebrates was evaluated, vegetation was described, morphological and physical-chemical analysis of soils as well as correlation analysis of quantitative indicators of soil mesofauna with chemical properties of soils of surveyed sites was performed for the first time on 10 survey sites. All surveyed biotopes have typical for the Ural taiga zone floristic composition and fauna of litter and soil invertebrates. At the same time, vegetation synanthropization is pronounced in all studied forest and meadow phytocenoses. The composition, structure and abundance of invertebrate mesofauna in all studied biotopes depend on the phytocenosis type, litter composition and thickness, the degree of soil and litter moisture. Correlation analysis revealed a relationship between soil acidity level and quantitative indicators of Lumbricidae and Oniscidea. The natural communities studied are affected by anthropogenic factors such as land reclamation, changes in soil composition and structure caused by mechanical disturbances during road construction, etc.
