Abstract

The influence of urban roads on the trophic structure of ground invertebrate communities was studied. Urbanization of the territory, the constant increase in the intensity of urban transport is inevitably accompanied by a chain of negative phenomena, and, above all, the excessive accumulation of various gas and dust-like pollution in the atmosphere, which leads to irreversible destruction of the surrounding landscape and the biosphere as a whole. Determining the degree of anthropogenic impact was carried out by methods of biological indication using soil mesofauna as test objects. For 10 study sites located within the city of Orenburg, vegetation and car load are described. The highest density of traffic was observed at the town of Vishnevaya – the Caspian Sea forest belt (40 aut./min.) And in the roadside territory of the bypass road (39 aut./min.). The smallest load of motor transport is recorded on the roadside area at Kushkul - 22 buses / min. It has been established that the representatives of the taxa Carabidae (Ground beetles), Silphidae (Mert-eaters) and Dermestidae (Crosheds) are numerically dominating near the highways. The representatives of these families are not fastidious to environmental conditions and are predators without much specialization. It was established that the Park of the 50th Anniversary of the USSR belongs to the most disturbed zone among the territories located at a distance from the road.
