“…Ecosystem engineers influence the rate of decomposition of dead plant residues through their fragmentation and subsequent dispersion in the terrestrial ecosystem (Sjursen et al, 2005), and, therefore, the rate of matter turnover and the release of ash chemical elements. These are, first of all, such representatives of the mesofauna as typical saprophages, e.g., earthworms (Lavelle et al, 2007;Berke, 2010;Kitz et al, 2015), two-legged centipedes (Gudym, 2016), lice (Striganova, 1980;Toth et al , 2016), as well as particular representatives of the microfauna like oribatid mites (Smrž, 2004;Gormsen et al, 2006). Their activity is mainly connected to the provision of such ecosystem services as increasing soil fertility and participation in nutrient turnover.…”

Earthworms (Oligochaeta: Lumbricidae) are typical representatives of the functional group of ecosystem engineers. They actively participate in formation and stabilisation of soil fertility through their effect on its buffer capacity. Buffer capacity defines in many aspects soil potential, supports immobilisation and mobilisation of certain elements of fertility, and first of all mineral elements essential for plants, productive moisture, heat energy of soil, gas composition of soil air, etc. Park soils within megapolises territory are megapolises' integral components, and this feature defines conditions of growth and development for green plants. To evaluate the contribution of earthworm coprolites into acidic-base (pH) buffer capacity of two categories of soil within the city, i.e., urban soils and urban grounds (urbanozems) of the park zones within the plots planted with Norway maple (Acer platanoides L.) trees on the territory of two parks Zeleny Gai and Pisarzhevsky Park (city Environmental Research, Engineering and Management 2019/75/1Dnipro, Ukraine), soil and coprolites samples were collected. Buffer capacity of coprolites and anthropogenically transformed soils (urban soils) was evaluated according to the Arrhenius method after "a buffer area". It was established that acid-base buffer capacity of coprolites (earthworm excretes), which are new formations of zoogenic origin in soil, was statistically significantly higher than for the initial type soil within city parks. For urban soil with the upper humified layer of calcic chernozem within the acidic diapason of external load, it was 22.9% higher, which, on average, accordingly was 22.9 and 18.7 convectional units; within alkaline, it was 18.4% higher and was, accordingly, 24.2 and 20.4 convectional units; and in sum (acidic-alkaline), it was 20.6% higher and was 47.1 and 39.1 convectional units. For urban ground (urbanozem) within the acidic diapason of external load, it was 44.9% higher and acidic-alkaline buffering capacity, on average, accordingly, was 25.5 and 17.6 convectional units; in sum (acidic-alkaline), it was 20.6% higher and was 42.8 and 35.4 convectional units, accordingly. Thus, soil saprophages, such as earthworms, in the conditions of magapolises in the recreation zones within the territories of city parks' green plantations are one of the natural factors of ecological rehabilitation of urban soils. This, in general, improves the ecological state of green plantations on urban soils within park areas and recreation zone edaphotope revitalisation as well as supports optimisation of human living and recreation environment.

“…Among the soil invertebrates-saprophages, one of such representatives are millipedes (Myriapoda: Diplopoda). They play a key role in the primary decomposition of plant litter, the processes of soil formation and in soil biogeochemical cycle (Striganova, 1980;Gudym, 2016). They interact with fresh, recently fallen leaf-litter in the soil and mechanically grind it, improving the accessibility for treatment by microorganisms (Masse et al, 2018).…”

Diplopoda play an important role in the processes of creating and maintaining soil fertility by implementing leaf litter destruction at its initial stages. Recently, in Ukraine the problem of soil fertility restoration has acquired a great urgency due to climate changes (aridity and temperature rising) and constantly increasing anthropogenic impact on natural biotopes, which often have Diplopoda as its element. The aim of this study was to evaluate the integrity of linear morphological characteristics of experimental animal Rossiulus kessleri (Lohmander, 1927) in different forest biotopes within semi-arid climate of the steppe zone. To determine the interrelation of morphological features, the method of correlation pleiades was used. It is established that 14 studied morphological characteristics of R. kessleri form the most powerful correlation pleiades with relative intensity values 0.64 and 0.93, within natural subwatereshed-ravine landscape and terrace flood plain forest conditions respectively. However, weakened one with 0.07 relative intensity value is observed within standing forest. Generally, the integrity of morphological characteristics of millipedes is increasingly prominent in the natural forest biotopes and extremely low in forest stands. Morphological variability of diplopods identified sylvatization degree of julidae's habitat. Relative potency value of correlation pleiades can be used for diagnostics of forest stands naturalization within the steppe zone of Ukraine.

“…An important role among the animal population in transformation of dead plant material belongs to ecosystem engineers -animal environment-creators Grimaldi et al, 2016, which contribute to soil structure formation at the most important stage -biochemical process of humification, as the result of their pedoturbation and trophic activity, which ultimately leads to transformation of forest ecosystems on recultivated plots. First of all, such representatives of mezofauna -typical saprophages as earth worms should be mentioned (Eisenhauer, 2010;Jouquet et al, 2014;Kitz et al, 2015;Cunha et al, 2016;Amossé et al, 2015), millipedes (Gudym, 2016;Pokhylenko et al, 2019), woodlice (Zimmer & Topp, 1998;Toth et al, 2016), and particularly important representatives of microfauna -oribatid mites (Smrž & Norton, 2004;Gormsen et al, 2006;Wehner et al, 2018). Their activity is connected mainly with provision of such important ecosystem services as increase of soil formation and nutrient turnover.…”

The study of morpho-ecological organization of oribatid mite communities (Acariformes, Oribatida) inhabiting forest litter of recultivated areas in steppe zone conditions of Ukraine was performed. The role of the forest and forest floor litter in optimization of the ecological situation on degraded lands was demonstrated. The function of environment creation by oribatids, as primary destructors of dead plant matter, supporting such ecosystem services as soil fertility improvement and nutrients turnover was highlighted. The research was performed within different stratigraphic types of bulk edaphotops in the recultivated plot of “Pavlogradskaya” colliery (Pavlograd, Dnipropetrovsk region, Ukraine) planted with red juniper (Juniperus virginiana L.). Withdrawal and collection of mites was performed with thermoeclector. For determination of the domination structure in the mite communities, the Engelmann scale was used. Adaptive (morpho-ecological) groups of oribatid mites were diagnosed by Krivolutsky. It was established that the number of species of oribatid mites in the forest litter of the studied red juniper plantation varied from 16 to 25. Average density of oribatid mites varied from 4,720 to 25,327 ind./m2. Among such morpho-ecological groups as soil surface inhabitants, small soil pore inhabitants, deep soil forms, floor litter inhabitants and unspecified forms, identified in the coniferous litter, the share of unspecified forms increased from loess-like loam type (21% of total amount) to Calcic Chernozem types with different stratigraphy (41.0%, 70.0% and 70.4% accordingly). Deep soil forms in the forest floor litter of the studied red juniper plots were not identified for any of recultivation types. The obtained results expand our understanding of the role of oribatid mites in the processes of ecological rehabilitation of disturbed ecosystems in the conditions of modern nature management.
