Brushnivs’ka L. The structure of spider (Araneae) communities as an indicator of technogenic air pollution of urboecosystems (on the example of the city of Chernivtsi)

The dissertation research deals with the study of structural organization of spider communities of ecosystems with different levels of technogenic air pollution of the city of Chernivtsi. For the first time it has been distinguished the qualitative and quantitative characteristics of assemblages which inhabit both premises and green areas of 10 industrial enterprises of the city of Chernivtsi. It has been established that the species richness of spiders-herpetobionts communities of soil surface decreases with the increase of hemerob ecosystem level.Theoretical generalization of coenotic reactions of spiders-herpetobionts communities of the industrial zones has been highlighted. We have singled out synecological indices as well as spider species whose presence testifies of the level of technogenic air pollution of the territory.
