The study of the Late Neopleistocene and Holocene molluscs from caves of the Southern Urals demonstrated that, despite the fact that the complexes in different periods are represented by similar species of molluscs, the predominance of some species over others and mollusc shells numbers make it possible to reconstruct the palaeoecological environments of the past. It was discovered that molluscs during Tabulda time (MIS 3) inhabited forest biotopes in a temperate climate and moderate humidity; in some places on the slopes, there were steppe and arid areas; in the Kudashevo time (MIS 2), molluscs lived in a moderately cold climate among shrubs, in woodlands, on open slopes. During the early Holocene, in a temperate climate, molluscs were predominantly found in open spaces — on the rocks of southern slopes and in woodlands with arid or slightly humid conditions; open spaces were widespread in the Middle Holocene; molluscs lived in meadows, valley forests and rocky slopes covered with light forests, the climate was temperate. In the Late Holocene, under conditions of a temperate and humid climate, molluscs inhabited mainly stony slopes with woodlands and open meadows, where conditions were more arid, less often they were found among shrubs and in woodlands under conditions of high humidity. Malacofaunistic data on the reconstruction of the habitat in the Late Pleistocene and Holocene are confirmed by palynological studies.
