“…However, if plants exert a preponderant influence on the rhizomicrobiota in natural contexts, the anthropogenic impact becomes the leading factor in shaping the urban soil microbial communities. Human activities such as building and road construction, industrial production, waste management, transport use, and the introduction of new plant and animal species reshape the urban environment and, consequently, the soil as its main component, ultimately affecting the urban soil microbial composition [112].…”

“…Such climatic alteration (due to the loss of tree cover, soil sealing that reduces evapotranspiration, and albedo reduction) can lead to the adaptation of certain microbial species to higher temperatures, affecting the overall urban soil microbial community composition. Moreover, the increased tolerance to high temperatures can favor the emergence of new opportunistic pathogens (such as Candida auris), with potential implications for human health [112,113]. In addition to the correlation with human health, changes in urban soil biodiversity owed to human disturbance lead to modifications in the structure and functioning of the food web.…”

“…This influences soil microbiota by affecting soil moisture levels and water infiltration rates, leading to water stress in bacteria. On the other hand, due to the widespread soil sealing in metropolitan areas, flooding is also common in urban soils [112]. Flooding can result in anoxic conditions that drive shifts in microbial community composition due to changes in available electron acceptors and altered chemical and physical soil properties.…”

The urbanization process, which began with the Industrial Revolution, has undergone a considerable increase over the past few decades. Urbanization strongly affects ecological processes, often deleteriously, because it is associated with a decrease in green spaces (areas of land covered by vegetation), loss of natural habitats, increased rates of species extinction, a greater prevalence of invasive and exotic species, and anthropogenic pollutant accumulation. In urban environments, green spaces play a key role by providing many ecological benefits and contributing to human psychophysical well-being. It is known that interactions between plants and microorganisms that occur in the rhizosphere are of paramount importance for plant health, soil fertility, and the correct functioning of plant ecosystems. The growing diffusion of DNA sequencing technologies and “omics” analyses has provided increasing information about the composition, structure, and function of the rhizomicrobiota. However, despite the considerable amount of data on rhizosphere communities and their interactions with plants in natural/rural contexts, current knowledge on microbial communities associated with plant roots in urban soils is still very scarce. The present review discusses both plant–microbe dynamics and factors that drive the composition of the rhizomicrobiota in poorly investigated urban settings and the potential use of beneficial microbes as an innovative biological tool to face the challenges that anthropized environments and climate change impose. Unravelling urban biodiversity will contribute to green space management, preservation, and development and, ultimately, to public health and safety.

“…Bioindication helps to determine the nature and extent of anthropogenic impact on the soil cover in the early stages of the degradation process development (Abramyan, 1992; Badiane, Chotte, Pate, Masse, & Rouland, 2001; Gorovtsov, Rajput, Gorbov, & Vasilchenko, 2017). An assessment of the biological activity of soils can be used to quickly diagnose the intensity of soil processes and the nature of their changes, which is especially important for revealing the functional role of soils in the biosphere (Marfenina, Karavayko, & Ivanova, 1996; Huot et al, 2017).…”

Enzyme activity of soils in urban landscapes of the lower Don area, Southern Russia

Soils are the main component of the urban ecosystem and they perform environment‐forming and protective functions. The dynamics of the organic matter and enzymatic activity is an early diagnostic indicator of negative changes in urban pedogenesis. However, the features of the enzymatic activity of urban soils of the Chernozem zone are poorly studied, and the available research focuses on the upper humus‐accumulative horizons or the urbic horizons. The study aimed to reveal the regularities of the enzymatic activity distribution through 200 cm in the profile of urban soils and to show their relationship with the content of the main soil components. Urbic Technosols Molic, Ekranic Technosols, Urbic Technosols, Technic Chernozems (caChernozems of fallow and virgin areas of the Rostov Agglomeration were studied. Soil samples were taken down to a depth of 200 cm. The activity of extracellular enzymes was determined by the fluorescence method. Soil organic matter content was determined by the high‐temperature combustion method on a TOC analyzer. А number of patterns in the distribution of the enzymatic activity have been identified. Most of the Urbic Technosols were characterized by a low enzymatic activity. Factor analysis showed a negative correlation of oxidative and hydrolytic enzymes in natural soil. A positive correlation of oxidases with hydrolases was shown in urbanized horizons. We found that the longer the time of sealing, the stronger the inhibition of enzymatic activity. We conclude that enzymatic activity can be used as an indicator in biodiagnostics, biomonitoring, and bioindication of the urban soils.

“…This has helped to reveal the certain regularities of urban soils and to outline the approaches for using them with a bioindicatory purpose. The search for bioindicators which make it possible to simultaneously assess a whole complex of ecologically significant factors in urban conditions, is being conducted by scientists among different groups of organisms (Meuser, 2010;Stankovic et al, 2013;Bessolitsyna et al, 2013;Gorovtsov et al, 2017).…”

In assessing the ecological conditions and classification of urban soils, data about soil biota should be taken into account. The environment of urban territories is characterized by significant changes compared to their surrounding environments. It is established that the algal flora of urban soils lose their zonal features and features associated with the edification influence of higher plants. Specific biotopes with a definite species structure are formed in urboecosystems. Fifty 50 algae species have been recorded in the soils of the Henichesk urboecosystems (Kherson region, Ukraine): Cyanoprocaryota – 21, Chlorophyta – 13, Charophyta – 2, Eustigmatophyta – 1, Xanthophyta – 11, Bacillariophyta – 2. Among dominant and subdominant species were Cyanoprocaryota and Chlorophyta. The other phyla were represented by Klebsormidium dissectum, K. flaccidum, Hantzschia amphioxys, Eustigmatos magnus, Botrydiopsis eriensis. Compared with the surrounding environment, the urbanized flora of Henichesk has a low species richness, and is characterized by prevalence of Cyanoprocaryota and Chlorophyta species. The coefficient that takes into account the percentage of preservation of species richness in a particular urban area compared to the background indicators of species richness can be used to evaluate the urban transformation of soil biota. The degree of degradatory changes in the composition of living organisms and the direction of these changes depends on the specificity and intensity of exploitation of the territory of the urban ecosystem. The most diverse composition of algae species within the the city of Henichesk was noted in the recreational, residential, and transport zones, in comparison with the industrial zone and the zone of special use. Different functional areas of the city are distinguished not only by the algae species richness, but also by the composition of dominants. Among the dominants and subdominants of the recreational and transport zones were species of different phyla. The dominants and subdominants of the residential and industrial zones were Cyanoprocaryota species, in the zone of special use – representatives of Chlorophyta. The distribution of species richness of algae along the soil profile in the city acquires an atypical character. The species richness increases not in the most superficial layers of soil, but in the lower, aphotic parts of the soil profile. The soil biota, on the one hand, depends on the ecological conditions of soil, and on the other as a result of its life activity, changes the ecological functions of the soil, strengthening or weakening them. The reduction in the species richness of the soil algae of the urboecosystem Henichesk shows the limitations of ecological functions of urban soils. It is established that changes in the composition of algae in soils of urban ecosystems are one of the indicators of the presence and severity of transformation processes. These processes occur with the soil biota and soil as a whole under the conditions of urban ecosystems and can be used as indicators in the environmental assessment of urban soils, in the development and subsequent examination of ways to reduce negative expression of urbanization.
