The analysis of the level and long-term dynamics of the incidence of ixodic tick-borne borreliosis, the population's appeal for tick bites and the infection of mites with Borrelia burgdorferi sl. in the Moscow, Ryazan and Tula regions. An annual increase in the incidence of Lyme disease in the direction from the south to the north, from the forest-steppe to the southern taiga, was determined, due to the frequency of contacts of the population with Ixodes persulcatus Shulze 1930 and I. ricinus L. 1758. At the same time, a statistically significant relationship between the incidence of mites infection and the incidence of Lyme disease in The studied regions are not observed. The obtained results testify to a tense epidemic situation in the center of the European part of Russia and the need to implement all components of surveillance for the natural foci of the Lyme disease.

Epidemiological Characteristics

Ixodes tick-borne borrelioses occupy one of the leading places in terms of morbidity and socio-economic damage among the natural foci of zoonotic infections in our country. Expansion of the range distribution of pathogens Lyme disease along with the widespread increase in the size of the main vectors of infection (ticks) determines the relevance of the study of the epidemiological characteristics of Lyme disease in areas that until recently were considered safe from the disease. This study was conducted to identify the level, dynamics and disease distribution patterns of Ixodes tick-born borreliosis in areas of Сentral European part of Russia, located in different climatic zones. Based on statistical data and reports from the Russian Federal Service for Oversight of Consumer Protection and Welfare- Rospotrebnadzor and Center of Hygiene and Epidemiology in Moscow, Ryazan and Tula regions for the 1992-2015 years, it has been shown that the incidence of Lyme disease increases moving from south to north as well as from the forest-steppe natural-climatic zone to the southern Taiga zone. The most epidemiologically disadvantaged region by Ixodes tick-born borreliosis amongst the studied regions was Moscow region, where the average annual incidence rate was 2,6 per 100 000 population. In all three areas, despite the differences in the species composition of mites and their degree of infection, there is an annual increase in morbidity due to Lyme borreliosis. The findings confirm the need for preventive measures against Ixodes tick-born borreliosis, the most significant being territorial coverage with acaricidal treatments.

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.

The Difference

Currently, the principle of sustainable use of forests is a fundamental direction in the management of natural resources. Solving the problems of sustainable development of forestry in the European North involves ensuring the quality reproduction of forest resources. The main parts of silvicultural production are procurement and preparation of seeds; growing planting stock, creation of new stands and agricultural tending of them. The goal of the federal project “Forest Conservation” is to ensure the balance of forest felling and reproduction in the ratio of 100 % by 2024. The emphasis is on the use of ball-rooted planting stock for artificial reforestation. Information gap on the long-term prospects of its use, as well as the lack of data on the results of long-term observations of growth and condition of forest crops created by seedlings with a lump of substrate, and comparison of such seedlings with traditional planting stock, especially in northern conditions, update the topic of research. The research purpose is to identify conditions for obtaining high-quality planting stock, as well as to assess the possibility of successful restoration of pine on felling sites in the north of the European part of Russia by creating forest crops using regional intensive technologies, based on the results of long-term technologies. The main objects of observations are nurseries of the region, the procedures used in them and the experimental planting of pine trees in the Kargopol and Arkhangelsk forestries in 2000–2001. Preservation, diameter, height, and volume were determined in dynamics in the areas of crops created from various types of planting stock (seedlings, plantlet, ball-rooted planting stock). The counts were carried out with several repetitions and dividing plants into healthy, weak and dry. Wood flaws of pine trunks were also noted and natural regeneration was recorded. Based on the research materials, the possibility of successful restoration of pine trees on felling sites in the north of the European part of Russia is shown using regional intensive technologies for the production of various planting stock and the creation of forest crops. This will reduce the period of transfer of young trees to natural conditions and increase the productivity of plantations. Comparison of average diameters and heights for all accounting periods indicates the influence of the type of planting stock and density of planting on the growth and development of trees. During the observation period, plantlets lead in all respects. Their height and diameter is 20–44 % higher than that of yearling seedlings, and in terms of stem volume the difference with other types of planting stock reaches 1.9–2.9 times.

The paper describes the methodology and presents the results of the calculation of the spectral characteristics of the terrain for the territory of the Bolshezemelskaya and Malozemelskaya Tundra (the north of the European part of Russia). There are nine terrain clusters, differing in the topographic dissection pattern. Their geomorphological interpretation is given. Three clusters characterize mountainous and coarsely hilly terrain with the depth of dissection from 150 m and more. The others are low and elevated terrains with much lower depths of dissection (up to 50 m) and different patterns of interposition of landforms.

The spatio-temporal variability of the average values of temperature indices of climate extremity in the territory of the European part of Russia (ER) in 1980-2019 is presented. To calculate the extremeness indices, we used hourly data on the maximum and minimum temperatures obtained using the ERA5 reanalysis on a 1°´1° spatial grid. Statistical processing of the index values revealed an increase in the temperature indices TNX, TNN, TXN, TXX, associated with the minimum and maximum temperatures, with the exception of the north and southeast of the region. An increase in the number of sunny days and a decrease in the number of frosty days were also revealed.

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.

ABSTRACTThis article focuses on radiocarbon (14C) dating of the organic matter (OM) of natural-anthropogenic objects—the cultural layers (CLs) of archaeological sites. Using examples from three ancient sites located within the European part of Russia, in southern taiga and forest-steppe natural zones, we demonstrate approaches to the interpretation of 14C dating of OM derived from the organomineral material of the CLs studied. We use the term “archaeological humus” as defined as the OM formed within the CL from “anthropogenic matter” (i.e., organic residues that were produced during the past human occupation of the site) without or with negligible contribution of OM inherited from pre-anthropogenic stages of pedogenesis. The archaeological humus is formed within closed or semi-closed systems by the processes of humification and physical stabilization of OM. The use of hierarchical (from macro- to submicro-) morphological investigations at one of the sites (Gnezdovo) combined with 14C dating allowed conclusions to be drawn about the age of formation of different OM components in CLs.
