Реликтовые группировки наземных членистоногих (Arthropoda) на территории юга Среднерусской возвышенности и перспективы их охраны

Abstract

Geohistorically formed relict groups from the fauna of terrestrial arthropods of the southern of Central Russian Plateau contain more than 200 species, making 12 % of the total number of species known from this region. About 30 % of these have been recorded from denuded cretaceous slopes; 9.5 %, from primary oak- forests; and 8 %, from wetlands. Remaining 50 % occur in steppe meadows, also being often found in forest clearings and cretaceous areas. Extrazonal relicts and zonal (inside the plateau) anthropogenic steppe residues are the most sensitive to anthropogenic pressure, which must be accordingly given high priority when making a regional list of endangered species and defining strictly protected reserve areas.
