ABSTRACT. Analysis of 40 years of monitoring studies of the Carabidae complex in the 'Yamskaya Step' area of the Belogorye State Nature Reserve and adjacent territories provides a generalised list of ground beetle species recorded in the study area. This list includes 169 species, 24 of which have not been recorded in the last 20 years. The total list of ground beetle species of the 'Yamskaya Step' location for the 40-years period of research includes 148 species, including 11 species recorded for the reserve area for the first time. 45 species are constantly noted in the protected area. An analysis of the ratio of species recorded in the 'Yamskaya Step' location according to hygropreferendum and of the changes in the dominant group showed that after a period of mesophilization, observed in 2006–2009, there is currently a shift in the structure of the ground beetle community towards xerophilization. The previously noted ending to the changes of the biocenosis of the virgin meadow steppe of the 'Yamskaya Step' protected area in the surrounding biocenoses is currently not expressed. The upland plain area of the steppe is characterized by the uniqueness and originality of the species composition of ground beetles. Meadow-steppe mesoxerophiles such as Carabus estreicheri Fischer von Waldheim, 1820 and Carabus hungaricus Fabricius, 1792 continue to be a specific feature of the protected area, the number of which has noticeably increased here in the last few years.
KEY WORDS: fauna, insect, ground beetle, protected area, south of the Central Russian Upland, anthropogenic impact, climate influence.
