Features of insect species diversityin the forest plantings disturbed by anthropogenic impact

Abstract

Insects are universal objects for monitoring biogeocenoses. Wide distribution, close connection with various components of the environment and the abundance of individual species in disturbed ecosystems, the variety of responses to anthropogenic impacts, quick response to changes in the quality of the environment, as well as there is a clear correlation between the level of exposure and the degree of manifestation of the response time they make it possible to use insects as indicators. Green spaces are an important environmental protection and environmental-forming factor of the urban environment, which determines changes in the composition and structure of entomological complexes. At the same time, plantings of different types and environmental categories are in different conditions in relation to air pollution, that what determines the features of biodiversity and the balance of the population structure. Among the most significant among them are the exhaust gases of motor vehicles, various chemicals used to combat icing of the roadway in winter, as well as the selective destruction of weed vegetation within the decorative design of highways, etc. The need to study the responses to environmental pollution, manifested in changes in the composition and structure of entomofauna, the dynamics of the number and the change in the role of individual species in the transformed territories determines the direction of this study. The analysis of insect responses at the species level allows us to identify the consequences of the transformation of biocenoses, changes in faunal abundance, the structure of dominance and, as a result, determines the stability of ecosystems.
