Invertebrate animals – inhabitants of the soil layer (earthworms, mollusks, centipedes, arachnids, insects) in the process of their vital activity maintain the "health" of urban soils. They contribute to loosening and aeration of the soil, its enrichment with chemicals, participate in the decomposition of plant litter, and regulate microbiological activity.
The abundance and taxonomic composition of invertebrates reflect the state of urban soils and the ecosystem of the city as a whole, and the diversity of life forms and the ratio of adult and larval stages in specific habitats are good indicators of the influence of various anthropogenic factors.
The study of the soil population allows:
- to diagnose the condition of the soil cover as the main component of ecosystems and identify negative changes at an early stage, since invertebrates are sensitive both to the direct effects of various factors of the urban environment and to indirect changes in soil properties under the influence of these factors.;
- to assess the sustainability of urban soils and "green zones" and identify potential threats that may be caused by both high anthropogenic stress and isolation of these zones from natural communities.;
- to recommend urban soil sanitation measures to preserve the diversity and abundance of soil animals involved in self-purification and improvement of the soil and the urban environment as a whole.
At the master class, you will get acquainted with the main taxonomic and ecological groups of invertebrates living in urban soils and the principles of soil and zoological diagnostics; practice methods of accounting and recording invertebrates, analyzing zoological material from soil traps installed in urban "green zones"; you will be able to independently diagnose the state of the soil environment and the influence of negative factors.
