“…In spring after snowmelt and relatively low intensity of evaporation of moisture from the soil surface, the soil moisture content is significantly higher than in autumn [33,63]. The low precipitation in late summer and early spring, which is superimposed on the considerable intensity of moisture evaporation from the soil surface during the warm season, leads to a drastic reduction of its reserves in the soil [13,64]. These processes explain the differences in soil penetration resistance between spring and autumn, as there is an inverse relationship between the soil moisture content and its penetration resistance.…”

“…Human trampling of the soil causes most of the impacts that recreation has on soil and vegetation [11]. All soil components (mineral matter, air, water, dead organic matter and living organisms) are disturbed by trampling [12,13] short-term and long-term trampling reduced vegetation cover, plant height and species density, although the long-term impact was more pronounced than the short-term impact. Leaf litter biomass decreases and soil density increases with trampling intensity.…”

Recreation affects various components of ecosystems. A significant transformation occurs in the soil cover in urban parks. The physical properties of soil are sensitive indicators of the level of anthropogenic transformation, and also allow to assess the state of soil as a habitat for plants and soil animals. The question of quantitative patterns of soil properties variability under the influence of recreation is not solved. There is also little information on the spatial aspect of the variability of soil physical properties in urban ecosystems. The aim of our study is to test the hypothesis that the recreational loads cause the formation of spatial patterns of soil properties, which by their extent greatly exceed the zone of direct influence. The spontaneous walkways within an urban park were investigated as an example of recreational loading. The physical soil properties were measured on a regular grid. The distance to the walkway was treated as a proxy variable that indicates recreational load. The application of multivariate statistical methods allowed to reveal the components of the variation of soil properties of different nature. The effect of recreational load is superimposed on the natural variability of properties. The peculiarity of the influence of recreation consists in sharp increase of soil penetration resistance in the upper soil layers and decrease of this index in the lower layers. The recreational load affects the physical properties of the soil. The soil compaction is the main direction of transformation. This effect gradually attenuates with distance from the source of exposure while occupying a significant portion of the space. The variation of soil properties affects the redistribution of soil moisture and soil air, which significantly affects the living conditions of soil biota.

“…The broad-scale component may be generated by microrelief features, which are formed as a result of flooding [64]. The micro-relief features are places of concentration of forest litter and moisture [65,66]. These conditions are favorable for epigean soil animals and become foci of their development.…”

Soil fauna is an important functional component of terrestrial ecosystems. Several hierarchical levels of spatial organization of pedobionts communities can be distinguished: point level, ecosystem level and landscape level. Of particular importance is the ecosystem level of spatial organization where the results of interaction between soil animals and soil and plant environmental factors, as well as the results of the influence of factors of neutral nature are expressed to the greatest extent. The aim of the work is to test the hypothesis that the spatial patterns of soil macrofauna at the ecosystem level can be explained by ecomorphs. Soil animals were sampled in floodplain ecosystems in the Dnieper River valley. Animals were sampled according to a regular grid with recording of local coordinates of sampling points. At the same points, soil properties were measured and geobotanical descriptions of vegetation were made. Phytoindication assessment of environmental factors was carried out on the basis of vegetation descriptions. The soil animal community is represented by high taxonomic and ecological diversity. The spatial distribution of soil macrofauna is not random and is a consequence of environmental factors and causes of a neutral nature. The ratio of these factors varies depending on the scale level. The fine-scale level is represented by factors of neutral nature. Medium- and broad-scale components are determined by soil and vegetation factors. The main spatial patterns of variation in the soil animal community correlate with the ecomorphic features of the animals. The ecomorphic approach allows interpreting the information on the spatial organization of pedobionts communities.

An ecomorph reveals the relationship between organisms and the environment and reflects the level of their adaptation to the most important elements of the biogeocenosis. The eco-morphic approach to the analysis of ecological systems is a component of the concept of ecomorphic matrices. The ecomorphic matrices consist of blocks comprising the synecological properties of the soil animal community, each reflecting a particular aspect of its ecological features. The systemic combination of these characteristics is able to provide a comprehensive reflection of the diversity and functional state of the community. As a result of research on the territory of green areas in the city of Dnieper and Melitopol revealed 53 species or taxon species level representatives of soil macrofauna of the 48 genera and 32 families, 13 orders, 7 classes and 3 types. The article presents the biological and ecological characteristics of macrofauna species. Analysis of the ecomorphic structure of communities of soil macrofauna showed that in the cenomorphic structure prevail syl-vants, which represent 44.2% of the species richness of the community. Differences between com-munities Melitopol and Dnieper on cenomorphic structure statistically not reliable. Saprophages and predators prevail in trophic structure of soil macrofauna communities. Topomorphic structure of communities is dominated by epigeic forms (65.4%) and considerably exceeded by endogean forms (32.7%) Only one species represents burrowing soil animals – D. nassonovi. The community is dominated by mesophiles, which is typical for forest cenoses. Megatrophocenomorphs predomi-nate in the trophocenomorphic structure of the community. Aerophiles (48.1%) and subaerophiles (34.6%) predominate in the communities. The dominance of aeromorphs sensitive to the provision of air for breathing, indicates a satisfactory air regime in the soil green areas of public use. Carbon-atophiles are most represented in the community. Communities of soil macrofauna of public green spaces has features of amphicenosis, in which steppe and meadow components are significantly represented against the background of predominance of forest component. Tree plantations in a city park form a common forest environment, although they do not form a stable forest monocenosis. Recreation and other forms of anthropogenic influence do not allow the formation of a forest mono-cenosis or pseudomonocenosis. The trophic aspect of the structure deciphers the importance in the community of the cenotic components. The trophic structure of sylvants repeats the trophic structure of the community as a whole and this allows us to consider sylvants as the functional basis of the soil fauna community. Phytophages prevail among sylvanians, which fully corresponds to typical trophic structure of steppe zonal communities. This peculiarity taking into account proportional representation of zoophages and saprophages allows to estimate as functionally stable structure of the steppe community.
