Aim. A study of the prevalence of West Nile virus (WNV) genetic lineages and genovariants in the south of European Russia between 2010 and 2019.Materials and methods. The study was carried out on 311 WNV containing biological samples from patients, vectors and reservoirs of infection. WNV typing was carried out using reverse transcription and real-time polymerase chain reaction with designed three pairs of primers and three probes and by the sequencing of the 277 bp WNV genome region corresponding to the 5'-untranslated region and locus of the polyprotein gene encoding the capsid protein C. Sequencing results were analyzed using the Nucleotide BLAST software (NCBI).Results. As a result of typing, out of 311 WNV RNA isolates taken for the study, 15 (4.82%) were assigned to lineage 1 (from Astrakhan and Volgograd regions, Krasnodar and Stavropol Territories, Republic of Tatarstan), 285 (91.64%) to lineage 2 (from Astrakhan, Volgograd, Voronezh, Kursk, Lipetsk, Penza, Rostov and Saratov regions, Krasnodar and Stavropol Territories, Republics of Kalmykia and Crimea), and 11 (3.54%) to lineage 4 (from the Volgograd region, Republics of Kalmykia and Crimea). The predominance of viral lineage 2 was demonstrated. The identified isolates of the viral lineage 1 belonged to the «Astrakhan» variant, isolates of lineage 2 belonged to «Russian» and «European» variants. Previously uncommon WNV variants of lineages 1 and 4 were also found.Conclusion. Lineage 2 of WNV prevailed in the south of European Russia in the last decade. The «Russian» variant is most common and its area is expanding. The circulation of various WNV genetic lineages in Russia indicates the need for further study of their spread and improving diagnostic methods and test systems for identifying and differentiating pathogen strains.

The remains of “early” mammoths from a number of localities of the late Middle—early Late Pleistocene on the territory of the South of European Russia (the basin of the Don River, Rostov Region) are described. The description of the teeth and bones of a postcranial skeleton is given. Teeth characteristics (number of plates, lamellar frequency and enamel thickness) allow determining the finds as Mammuthus intermedius, described from the territory of France but known from other regions of Western Europe and Western Siberia as well. In Eastern Europe, this form was a typical representative of the Khazarian theriocomplex and existed during the MIS 5–7 interval. This mammoth taxon differs noticeably from the typical woolly mammoth M. primigenius, which appeared in continental Europe during MIS 4.

A Promyialges pari Fain, 1965 (Analgoidea: Epidermoptidae) feather mite was found on the louse fly Ornithomya avicularia L., 1758 (Diptera: Hippoboscidae), recovered from Eurasian rook, Corvus frugillegus L., 1758 (Passeriformes: Corvidae), in the south of European Russia. This is the first record of P. pari in Russia and on the aforementioned bird host.

Changes in the characteristics of spring-summer droughts in the south of European Russia (twelve regions) in the period 1901-2018 were studied using the Standardized Precipitation Index (SPI) and analyzed in the periods of increasing/decreasing humidifying estimated by the Aridity Index (AI). In each studied region, the trends of aridization for centrury and more are not found. In the meantime, long-term interdecadal periods of increasing and decreasing aridization are detected. They are characterized by significant variation of frequency and intensity of spring-summer droughts. Decreasing aridization in the early 20th century over most of the south of European Russia has been replaced by aridization increase in 1930s. The period of increasing humidifying of the whole investigated area from 1960s to the end of 20th century changed to the period of increasing aridization. During dry periods, frequency of drought increases in 1.5 times, while drought intensity growth is insignificant. In actual dry period, beginning with the early 21th century, spring-summer droughts have emerged earlier in eastern part of South of European Russia; however, in western part drought are observed more often.

New data on 22 species of bees of the family Megachilidae from the North Caucasus and the south of European Russia are reported. Six species are new to Russia: Hoplitis curvipes (Morawitz, 1871), Osmia cinerea Warncke, 1988, O. ligurica Morawitz, 1868, O. cyanoxantha Pérez, 1879, Protosmia glutinosa (Giraud, 1871), and Coelioxys mielbergi Morawitz, 1880. Hoplitis turcestanica (Dalla Torre, 1896), sp. resurr. is treated as a distinct species, not a junior synonym of H. caularis (Morawitz, 1875). Megachile albocristata Smith, 1853 and M. alborufa Friese, 1911 are listed instead of previously recorded M. lefebvrei (Lepeletier de Saint-Fargeau, 1841) and M. pyrenaica (Lepeletier de Saint-Fargeau, 1841), respectively. Fourteen new regional records are reported: seven species are new to the North Caucasus, five ones are new to the south of European Russia, and two species are new to the European part of Russia as a whole. The numbers of megachilid bee species currently known in Russia, the North Caucasus, and the south of European Russia are 217, 130, and 71, respectively. The lectotype of Osmia proxima Morawitz, 1875 is designated.

Zoya Ilyinichna Glezer is the largest Russian micropaleontologist, a specialist in siliceous microfossils — Cenozoic diatoms and silicoflagellates. Since the 1960s, she systematically studied Paleogene siliceous microfossils from various regions of the country and therefore was an indispensable participant in the development of unified stratigraphic schemes for Paleogene siliceous plankton of various regions of the USSR. She made a great contribution to the creation of the newest Paleogene schemes in the south of European Russia and Western Siberia, to the correlations of the Paleogene deposits of the Kara Sea.
