“…New-Euxinian regression was in LGM (about 25 -15 kya) but it the final stage ended about 9 kya. Later, during the Atlantic, sea level gradually increased but was below modern and Crimea remained part of mainland (Ivanov et al, 2018). Former steppes were forested what caused the disintegration of the Common hamster range and isolated Crimean populations from mainland.…”

“…The Phanagorian regression that took place about 2500 years ago (Semikolennykh et al, 2018) may be a suitable time for it. Then the sea level fell by about 5 m, which led to the disappearance of the shallow parts of the Sea of Azov, including the Sivash channels (Ivanov et al, 2018;Mishchenko et al, 2018;Semikolennykh et al, 2018). In any case the presence in Crimea E0 phylogenetic lineages (either native or invasive) only suggests that Eastern and South-Eastern parts of Ukraine, from Southern Sumy province to Dnieper mouth, is populated by E0 phylogroup hamsters.…”

The Common hamster (Cricetus cricetus) is the rodent with one of the largest range (6 million km 2). There were four phylogenetic lineages earlier recovered in Western Europe, Ukraine and Bryansk Province of Russia: "North", "Рannonia", E1 and E0. E1 was previously reported from SouthEastern Poland and Western Ukraine and never been found in sympatry with "Pannonia" although the closest distance between them was estimated as 20 km. The question is whether the sympatry of E1 and E0 phylogroups exists? Special survey was arranged across Moscow, Tula, Bryansk, Oryol, Kursk, Voronezh and Lipetsk provinces to get the answer. Sequence analysis of the mtDNA control region and the cyt b gene from the tissue samples was carried out in the common hamsters captured in these areas and their belonging to a certain phylogroup was determined. For the first time a case of sympatry was revealed-in the city of Mtsensk vicinity (Oryol province). Here we discovered hamsters the both lineages-E0 and E1 at the same habitat. Hypothetically E1/E0 ranges boundary runs from Ukrainian Sumy province to NorthEast by line dividing the Russian Kursk and Oryol provinces. The existence of subclades within both E1 and E0 phylogroups suggests that diversification of phylogenetic lineages of the Common hamster in Eastern Europe may result from not single but multiple climatic events during the second half of Late Pleistocene. The phylogeographic structure of the species in Eastern Europe may be more complex than it currently known.

The article discusses the results of seismoacoustic studies of the shelf of the southeastern part of Crimea, carried out in 2020–2023 by employees of the P.P. Shirshov Institute of Oceanology RAS an seismoacoustic profiler. The obtained data made it possible to refine the position of the paleovalleys, to perform a seismostratigraphic reference of the reflecting horizons with the identification of the main seismic complexes in the pleistocene-holocene part of the section. Seismic facies analysis of the wave field made it possible to clarify the paleogeographic conditions for the formation of paleovalleys.
