“… Efimov et al (2008) determined the nucleotide sequences of mitochondrial genome fragments containing the genes coding for cytochrome oxidase subunit III and 12S ribosomal RNA of common European viper and Nikolsky's viper from various habitats. According to the sequencing data, the samples clustered into two groups.…”

“…According to the sequencing data, the samples clustered into two groups. One group comprised V. nikolskii from Saratov oblast and the other, V. berus from the Chuvash Republic, Republic of Mordovia, and Samara and Penza oblasts ( Efimov et al, 2008 ). Vipera berus nikolskii ( Vedmederja et al, 1986 ) snakes are distinguished both by lepidotic and coloration traits.…”

“…On the other hand, there are only few comparative molecular biological studies of the species [ 39 , 40 , 41 , 42 ]. Cytogenetic studies of the Vipera genus were carried out mainly on mitotic metaphase chromosomes or the preparation of meiocytes using light microscopy [ 43 , 44 , 45 , 46 , 47 , 48 ].…”

Vipera berus is the species with the largest range of snakes on Earth and one of the largest among reptiles in general. It is also the only snake species found in the Arctic Circle. Vipera berus is the most involved species of the genus Vipera in the process of interspecific hybridization in nature. The taxonomy of the genus Vipera is based on molecular markers and morphology and requires clarification using SC-karyotyping. This work is a detailed comparative study of the somatic and meiotic karyotypes of V. berus, with special attention to DNA and protein markers associated with synaptonemal complexes. The karyotype of V. berus is a remarkable example of a bimodal karyotype containing both 16 large macrochromosomes and 20 microchromosomes. We traced the stages of the asynchronous assembly of both types of bivalents. The number of crossing-over sites per pachytene nucleus, the localization of the nucleolar organizer, and the unique heterochromatin block on the autosomal bivalent 6—an important marker—were determined. Our results show that the average number of crossing-over sites per pachytene nucleus is 49.5, and the number of MLH1 sites per bivalent 1 reached 11, which is comparable to several species of agamas.

The Volga basin is one of the most industrially-developed regions of Russia with a high degree of anthropogenic impact on natural ecosystems. Human influence negatively affects the species diversity and number of animals, including reptiles. There are no endemic species in the reptile fauna of the Volga basin. The herpetofauna of the region makes up 25% of the reptile fauna of Russia (Dunaev and Orlova 2017). We began to study the fauna of reptiles and their distribution in the Volga basin in 1988. Although we registered 20 reptile species in the Volga basin to date, apparently this is not a complete list of species in the region (Bakiev et al. 2004, Bakiev et al. 2009a, Bakiev et al. 2015, Kirillov et al. 2020). The distribution of reptiles in this region is not fully understood. Our dataset contains information on reptile occurrences in the Volga River basin. The dataset is based on original research by the staff of the Laboratory of Herpetology and Toxinology and Laboratory of Population Ecology of the Institute of Ecology of the Volga River basin of the Russian Academy of Sciences and Joint Directorate of the Mordovia State Nature Reserve and National Park “Smolny”. A total of 5,086 occurrences of 20 species are published for the first time with georeferencing. Many of these reptiles are listed in regional Red Data Lists. The European Pond Turtle Emys orbicularis (Linnaeus, 1758) is included in the IUCN Red List with the category “Near Threatened”.
