Karst caves in the Ukrainian Carpathians are not numerous due to the limited extent of karst rocks in the region. Most known caves are concentrated in the Uhlja karst district, associated with the Marmarosh Klippen Zone. The known cavities are relics/fragments of ancient, probably Pre-Quaternary, hypogenic karst aquifer systems, partly destroyed an...
Article
The Crimean Mountains are well known from the abundance of Middle and Late Palaeolithic sites and palaeontological remains recovered from cultural layers in caves and rockshelters. The fossil-bearing deposits of Emine-Bair-Khosar Cave, located at the elevation of 1000 m on the Chatyrdag Plateau, yielded a very diverse and numerous vertebrate remain...
Article
The Emine-Bair-Khosar Cave (EBK), situated on the northern edge of the Lower Plateau of the Chatyrdag Massif (Crimean Mountains) is rich in palaeontological material accumulated over most of the Pleistocene. mtDNA was isolated from bones of three specimens of red deer (Cervus elaphus) dated to the late Pleistocene (MIS 3). These are the first ancie...

A letter submitted to the journal Science in reply to a letter by some ‘western’ scientists - Holdren et al.. “Let’s not abandon Russian scientists” (2022). We wrote because we detected a degree of detachment and aloofness in the original letter, and we found this unfortunate. And rather upsetting given that most of us are, or were, residents of Ky...
Article
The present phylogeographic pattern of red deer in Eurasia is not only a result of the contraction of their distribution range into glacial refugia and postglacial expansion, but probably also an effect of replacement of some red deer s.l. mtDNA lineages by others during the last 50 000 years. To better recognize this process, we analysed 501 seque...

Grey voles (subgenus Microtus) represent a complex of at least seven closely related and partly cryptic species. The range of these species extends from the Atlantic to the Altai Mountains, but most of them occur east of the Black Sea. Using ancient DNA analyses of the Late Pleistocene specimens, we identified a new mtDNA line-age of grey voles in...

Aim: The Expansion-Contraction model has been used to explain the responses of species to climatic changes. During periods of unfavourable climatic conditions, species retreat to refugia from where they may later expand. This paper focuses on the palaeoecology of red deer over the past 54 ka across Europe and the Urals, to reveal patterns of change...
