The article describes a new association of meso-xerophylous forests in the South of the European part of Russia Poo nemoralis–Quercetum roboris ass. nov. hoc loco, its differentiation from analogous syntaxa is discussed, and new data on the distribution of communities of the alliance Scutellario altissimae–Quercion roboris Goncharenko et al. 2020 on the Russian Plain are done. Vegetation classification was carried out by J. Braun-Blanquet approach based on 470 relevés of forest vegetation, collected by the author in 2007–2021 in the northern and central parts of Rostov, Voronezh and Volgograd Regions. In addition, the analysis included 777 relevés from the phytocenary made by G. M. Zozulin in the same regions in 1960–1980s. Based on the studies carried out, the current area of the alliance can be expanded to the lower reaches of the Don River. For a more adequate reflection of the floristic, ecological and geographical features of its communities, it was proposed to change the composition of the diagnostic species of the alliance and it was recommended to amend the current definition of the order Quercetalia pubescenti-petraeae, expanding its area to Eastern Europe.

The article presents the results of long-term research of ravine oak forests of the Rostov region.The term ‘bayrack’ (ravine) forest is associated with the growing of forests of this type on the slopes of ravines in the forest-steppe zone. The conducted ecological and floral classification showed a high syntaxonomic diversity of ravine oak forests of the region. Forest communities are represented by 6 associations: Scorzonero ensifoliae–Quercetum Sokolova ex Semenishchenkov 2020; Vicio pisiformis–Quercetum roboris Semenishchenkov 2012; Pyro pyrastri– Quercetum roboris Poluyanov 2012; Chamaecytiso ruthenici–Quercetum roboris Poluyanov 2012; Fritillario ruthenici-Quercetum roboris Onyschenko, Dyakova et Karpenko ex Goncharenko in Goncharenko et al. 2020, Melico pictae-Ulmetum minoris ass. nov. prov. from 2 classes: Carpino–Fagetea, Quercetea pubescentis and 2 unions: Aceri campestris-Quercion roboris and Scutellario altissimae-Quercion roboris. There are 67 rare plant species listed in the Red Books of the Rostov [1], Volgograd [2] and Voronezh [3] regions in the communities of these associations. Oak forests in the south of the European part of Russia significantly increase the biological diversity not only of the Don region, but also of the entire steppe zone of the country.

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.

The paper presents the results of geoinformation mapping of burned areas in zonal landscapes of the Astrakhan, Volgograd regions and the Republic of Kalmykia for 1998-2019. In total, over the studied period, more than 6 million hectares were covered by fire, more than 15 thousand fires were identified. The total burnt area, excluding recurrence, is more than 15 million hectares. Some areas have burned out up to 11-14 times in 20 years.

Introduction. When evaluating mudflow danger level and developing hydroengineering anti-mudflow measures, a great meaning is obtained by mudflow basin cadastres that are widely used as reference sources by water-economic project establishments, scientists, specialists of federal and local authorities. The cadastres influence the made decisions on development of the anti-mudflow measures and protective hydroengineering facilities, since the cadastres include basic dedicated data on mudflow basin locations, geophysical (geomorphometric, hydrological) characteristic and expected mudflow parameters. Materials and methods. The article uses known and proven methods of analysis of mudflow basin cadastres. The analytical methods are based on a comparative assessment of the presented results with basic geophysical data of primary sources (cadastres published earlier) and on-site investigations as well as compliance of the suggested empirical formulae on determination of mudflow carrying out volumes and indicators of territorial mudflow striking with mathematical and physical conditions of development of the real mudflow phenomena. Results. Critical analysis of the contents of the Cadastre of Mudflow Danger of the South of the European Part of Russia published in 2015 allows revealing multiple distortions and substitutions of basic geophysical data of mudflow basins. There is an inaccuracy (up to 3,000 to 4,000 % and even higher) of the empirical formulae used in the cadastre for determination of volumes of modflow carrying out. The analysis reveals a hydrogeographical error connected with unfounded substitution of the concept “river length” with the value of the “total length of the main course and all its inflows” that multiply overrates the calculated riverbed length and multiply underrates value of a riverbed bias. Also the study emphasizes unacceptability of definition of the mudflow danger territory by the principle “the water-collecting area of the mudflow course is totally mudflow-threatened" owing to which the absolutely safe natural landscapes are unreasonably declared mudflow-threatened territories. Conclusions. The stated analysis shows a discrepancy of the considered cadastre to the status of scientific and research work. In this connection, the cadastre cannot be recommended for use both in scientific researches and in practical ones. Recommendations on improvement of the mudflow basin cadastres are provided.

Demographic Processes

The paper presents the results of the demographic processes analyses study in the South of European part of Russia in comparison with national outcomes. The research is based on a GIS monitoring concept and reveals the main characteristics of population size dynamic pattern with the influence of prevailing reproduction processes. The main sources of data are the office for national statistics and various regional statistics sources. ESRI ArcGIS Spatial Analyst software platform is used as a primary analytical framework. The study case covers the time frame from 1959 to 2018. Developing map models of the population’s natural reproduction brings out the depopulation speed and direction as a primary trend in Russia’s demographic development. At the beginning of the XXI century’s third decade, there is a significant reduction in the number of regions with positive natural population growth. The regions with decreasing in population have prevailed. The positive natural population growth preserves mainly in national territorial subdivisions with an unfinished demographic transition. The demographic picture in the south of European part of Russia looks relatively propitious. Negative demographic trends arise with a delay and have not reached the critical levels yet. The obvious polarization of demographic space in the south of Russia has educed — there are two areas with unequal trends of population growth: South-East area with a sustainable increase in the population and a migration outflow, the North-West area with a natural decline in the population and an erratic positive migration balance. Though the area with a sustainable increase in the population is reducing, showing positive trends in Krasnodar Krai and Republic of Adygea. The ethnic republic’s migration outflow is stable.
