Abstract
In the subarctic regions of Krasnoyarsk Krai in 2022-2023, the population of ground beetles (Coleoptera, Carabidae) was studied at different distances from sources of anthropogenic impact. In the vicinity of Norilsk, the impact of metallurgical enterprises was studied; near Dudinka, the change in the ground beetle population along the urbanization gradient was studied; in the south of the Gydan Peninsula, the impact of gas condensate fields was assessed. The least impact on the ground beetle population was noted in the area of the fields. Urbanogenic impact in the vicinity of Dudinka affected ground beetle communities at a distance of up to 2-3 km. The complex impact of Norilsk facilities (industrial enterprises, urban infrastructure, etc.) on ground beetle communities was traced at a distance of up to 10-15 km. Near sources of anthropogenic impact, the number of ground beetle species in communities, their overall dynamic density, and the density of individual genera and species of ground beetles decrease: especially large-sized representatives (genus Carabus) and specialized arctic species of the subgenus Cryobius from the genus Pterostichus, associated with moss-lichen cover. These parameters can be used as indicators of environmental disturbance.
