Extensive collections of land molluscs from the many sections of Middle and Late Pleistocene deposits in the region of the Middle Dniester River were made by Professor Mykola Kunytsia (1925–2002). These collections, now at the Natural Museum, Yuriy Fedkovych Chernivtsi National University, were for the most part analysed, but remained partially unpublished. M. Kunytsia used them for regional reconstructions of palaeolandscapes during various stages of the Pleistocene. In our study, we used these collections to assess the land snail diversity in the region during consecutive stages of the Middle and Late Pleistocene. Our analysis of faunas of cold and warm stages showed that the latter were more diverse. While all or most of the cold stages had many species in common, the faunas of the warm stages were more heterogeneous. Such a feature may play an essential role in Quaternary biostratigraphy.

Mykola Kunytsia教授（1925年至2002年）从中德涅斯特河中部地区的中更新世晚期和晚期更新世沉积物的许多部分中广泛收集了陆地软体动物。这些收藏品目前在尤里·费德科维奇·切尔诺夫策国立大学自然博物馆中进行了大部分分析，但部分未出版。Kunytsia先生在更新世的各个阶段将它们用于古地理景观的区域重建。在我们的研究中，我们使用这些采集来评估中，更新世连续阶段该地区的蜗牛多样性。我们对冷热阶段动物区系的分析表明，后者的多样性更高。尽管所有或大多数寒冷阶段都有许多共同的物种，但温暖阶段的动物群却更加异质。
