In the West-Siberian northern taiga (the Yamal-Nenetz Autonomous District, vicinities of Noyabrsk city), 54 carabidae species  (Coleoptera) have been found.  The fauna of natural landscapes (forests, bogs, river flood-plains) contains a larger number of tundra-taiga species than the fauna of anthropogenous landscapes (sand quarries and burned-out forests) in which more taiga west-paleoarctic elements are represented. The carabidae population of natural biotopes is poorer and lower in numbers than that of anthropogenous biotopes, and they differ both at the level of species and genera.  Distinguished are complexes of stenobiont species of inconstant small lakes, flood plains, permafrost swamps; oligibiont species  of swamps, forests, open dry habitats; a wide eurybiont Carabus canaliculatus Ad.  Although biotopes with destroyed soil cover become populated by carabidae already the next year, this is not a fauna typical of northern taiga, but rather prevalent widespread species. Such an unstable structure is conserved for no less than 20 years, and it is only in a few decades that the structure approaches the natural one.
