Population of Ground Beetles (Coleoptera, Carabidae) and Their Bioindicative Value in the Subarctic Regions of Siberia (Norilsk Industrial Region and the Left Bank of the Yenisei)
摘要
In 2022–2023, the population of ground beetles (Coleoptera, Carabidae) was studied in the subarctic regions of Krasnoyarsk krai at different distances from sources of anthropogenic impact. The impact of metallurgical enterprises was studied in the vicinity of Norilsk, the change in the ground beetle population along the urbanization gradient was studied near Dudinka, and the impact of gas condensate fields was assessed in the south of the Gydan Peninsula. The least impact on the ground beetle population was noted in the area of fields. The urbanogenic impact in the vicinity of Dudinka affects ground beetle communities at a distance of up to 2–3 km. The cumulative impact of Norilsk facilities (industrial enterprises, urban infrastructure, etc.) on ground beetle communities is traced at a distance of up to 10–15 km. Numbers of ground beetle species in communities, their overall dynamic density, and the density of individual genera and species decrease near sources of anthropogenic impact, in particular, large-sized representatives (genus Carabus) and specialized arctic species of the subgenus Cryobius from the genus Pterostichus, associated with the moss–lichen cover. These parameters can be used as indicators of environmental disturbance.
