Hemeroby is an integrated indicator for measuring human impacts on environmental systems. Hemeroby has a complex nature and a variety of mechanisms to affect ecosystems. Hemeroby is often used to assess disturbances in different vegetation types but this concept has seldom been evaluated for animals. The role of the hemeroby gradient in structuring the soil macrofauna community was investigated. The experimental polygon was located in Botanical Garden of the Oles Honchar Dnipro National University (Dnipro City, Ukraine). There were 20 sites within the polygon. On each of them at 105 points samples of soil macrofauna were taken, soil penetration resistance, electrical conductivity of soil, depth of litter, height of grasses were measured. Within each site, a description of the vegetation cover was made. Based on the description of the vegetation, an indication of the level of ecosystem hemeroby within the polygons was conducted. In total, 48,457 invertebrate (Annelida, Arthropoda, and Mollusca) individuals of 6 classes, 13 orders, 50 families and 83 species or parataxonomic units were recorded. Phytoindication reveals that the level of hemeroby within the studied polygons varies from 34.9 to 67.2. The model V and VI from the HOFJO-list were the most optimal model of the species response to hemeroby gradient. The weighted average factor value was used to assess the optimal factor level for the species in a symmetrical bell-shaped response model. The optimal factor level of the hemeroby for the soil macrofauna species ranges from 34.9 to 66.0. Species also differ in degree of specialization to the factor of hemeroby. There was a regular change in the soil macrofauna community size and diversity in the hemeroby gradient. The limiting influence of anthropogenic transformation of the environment on the abundance of soil macrofauna community is clearly marked at the level of hemeroby above average. Species diversity of the community is greatest at moderate hemeroby level. Both relatively little transformed habitats and strongly transformed ones are characterized by lower species richness of the soil macrofauna community. The Shannon index shows a clear upward trend with increasing hemeroby. The Pielou index indicates that the main reason for this trend is an increase in community evenness with increasing hemeroby. The intermediate disturbance hypothesis was fully supported with respect to species richness. For the number of species, there is indeed a certain level of heterogeneity at which the number of species is highest. For another aspect of diversity, evenness, this pattern is not true. The evenness increases with increasing habitat disturbance. This result is due to a decrease in the abundance of dominant species.

This study established features of the animal population of artificial soil-like bodies – technosols in terms of ecomorphic analysis. The survey was conducted at the research station of the Dnipro State Agricultural University in the city Pokrov in 2012–2014. The experimental polygons were laid within four technosol types: pedozems, sod loess-like lithogenic soils on loam, grey-green clay and red-brown clay. The polygon consisted of 15 transects and each transect was composed of seven test sites. The distance between rows in the polygon was 3 m. Each test site was a square with size 3 × 3 m. The manual sorting of the soil-zoological samples was conducted within each site for areas 0.25 × 0.25 m to the depth where animals were found. Samples were taken in late April or early May. In general, for each period of counting for each polygon 105 soil-zoological samples were taken 123 species of invertebrates were found in the soil macrofauna community of the technosols. These communities are a steppe monoceonosis with a tendency to transformations into pseudoomonoceonosis on account of increased share of pratants. The soil macrofauna of sod lithogenic soils on grey-green clay and loam on loes-like clays is most adapted to xerophilous condition. Animal communities in pedozems and sod-lithogenic soils or on red-brown clay have a more mesophilic character. The trophoceonomorphic structure of the soil macrofauna community indicates a significant potential of the fertility of artificial soil. The aeromorphs’ structure reveals a significant ability of technosols to create cracks and pores, which can lead to hyperaeration. The dominant part of the of soil macrofauna community was hypercarbonatophils. Against the background of the steppe character, the soil macrofauna community had a topomorphic structure that is unusual for natural steppe black soil biogeocenoses on loess-like loam. The trophomorph structure was greatly dominated by phytophages, which indicates the prevalence of processes of mineralization of plant residues under the humification process. The phoromorphic spectrum of soil animal communities was dominated by ecological groups which move without the active construction of tunnels.
