Кормовое поведение самцов и самок большого пёстрого дятла (БПД) Dendrocopus major исследовано в Ставропольском крае в период 2013-2021 гг. В целом, зарегистрировано 58 посещений дятлами 12 видов кормовых деревьев. Выявлено предпочтение БПД следующих видов деревьев: дуб (22%), граб (20%), ясень (17%). Проведено сравнение кормовых предпочтений самцов и самок БПД в различные сезоны года. В холодный период БПД предпочитали разыскивать корм на стволах и толстых ветвях деревьев, где было больше шансов обнаружить зимующих беспозвоночных. Выявлены различия в кормовых методах, используемых самцами и самками БПД. We studied the feeding behavior of males and females of the Great Spotted Woodpecker (GSW) Dendrocopos major in the Stavropol Region over 2013-2021. In general, 58 woodpeckers’ visits to 12 forage tree species were recorded. The preference of GSW of the tree species was as following: oak (22% of visits), hornbeam (20%), ash (17%). A comparison of the feeding preferences of males and females of GSW in different seasons revealed that in the cold period the GSW preferred to search for food on the trunks and thick branches of trees, where it was more likely to find wintering invertebrates.

Despite the key role played by soil organisms in the functioning of terrestrial ecosystems and provisioning of ecosystem services (Barrios 2007, Bardgett and Putten 2014), available open data on soil biodiversity are incongruously scarce (Eisenhauer 2017, Cameron 2018). This is especially true for Russia, but contrasts long traditions of soil zoological research and large volumes of data that were collected during the second half of the 20th century for the territory of the former USSR. Last year, 41,928 georeferenced occurrences of soil-dwelling arthropods Collembola were digitised and published through GBIF.org. This work continues these activities. The article combines descriptions of three new sampling-event datasets about the various types of anthropogenic load on the diversity and the abundance of Collembola, small arthropods involved in the destruction of organic residues in the soil: Collembola of winter wheat fields in the Kaluga Region: conservation treatment versus conventional one (Kuznetsova et al. 2020). The following variants were studied: 1) treatment with organic fertilisers and tillage, without mineral fertilisers and pesticides, 2) the same, but without tillage, only discing; 3) with mineral fertilisers, pesticides and tillage. Special multi-scale sampling design was used. The material was collected on 24-26 July 2019 in Kaluga Region, European part of Russia. Data on 2226 records on 7302 specimens of 32 species in six fields in 486 soil cores are presented. Collembola of broadleaved forests along gradient of urbanisation in Moscow (Kuznetsova and Ageeva 2020). Sampling plots were placed in oak and lime forests located at different distances from the centre of Moscow. The material was collected in different seasons of 1990–1991. Data on 1737 records on 6873 specimens of 64 species (17 series of sampling, 720 soil cores) are presented. Collembola in clear cutting areas of Arkhangelsk Region: spatial and temporal series of the data (Kuznetsova and Klyueva 2020). Sampling plots were in birch forests of different ages with spruce underbrush and in old spruce forest. The study was carried out in July of 1970–1971 and 1984 in Arkhangelsk Region, European part of Russia. In 1970, cores were taken at sites where the forest was restored 15, 30 and 80 years after clear cuttings, as well as in a 180-year-old spruce forest. In 1984, sampling was repeated in two plots. Data on 1468 records on 18788 specimens of 47 species (seven series of sampling, 720 soil cores) are presented.

Data on 1468 records on 18788 specimens of 47 species (seven series of sampling, 720 soil cores) are presented. These datasets contribute to filling gaps in the global biodiversity distribution of the Collembola. All datasets present new information about effects of agricultural treatments, urbanisation and clear cutting on springtail diversity and abundance in ecosystems of the European part of Russia.

Abstract Phenotypic and genotypic diversity of populations of species of the yellow wagtails in the space of their ranges in a wide sympatry reflects the mechanisms of reproductive isolation of species and forms of subspecies rank and features of microevolution group - polytypic complex Motacilla flava Linnaeus, 1758. The distribution of species of the yellow wagtails in the European part of Russia is sympatric. The purpose of this study was to investigate whether sympatric settlement led to any genetic separation between the populations of these species. 20 blood samples and 2 samples of eggs collected in areas geographically representing the MID and the southern Russian breeding populations of these species, including all juvenile ringed in 2012, were used. After the polymerase chain reaction (PCR) 4 types of the yellow wagtails group Motacilla flava L., 1758; M. feldegg Michahelles, 1830; M. lutea (S. G. Gmelin, 1774); M. cilreola Pallas, 1776 (Passeriformes, Motacillidae) were sequenced. After aligning the sequences of the gene cytochrome oxidase I, based on the comparison of genetic distances between these species phylogenetic tree of genus Motacilla was constructed. These results suggest that, despite the broad sympatry in nesting places, there is a selective mating between males and females of each species studied in spite of the free crossing and insulating mechanisms in populations.

Sera of inhabitants of the European part of Russia, collected in 2010-2013 were studied with the use of ELISA and neutralization test. Antibodies to West Nile virus were detected in 19.6% of cases in the Astrakhan region, 4.5% - in the Krasnodar region, 0.9% - in the Saratov region and 5.4% - in the Stavropol region. The coincidence of the results of the examination of sera in ELISA-IgG and neutralization test accounted of 80.7% in the Astrakhan region, 72.2% - in the Krasnodar region and 69.2% - in the Saratov region. The presented results correlate with the incidence and duration of known epidemiological activity of West Nile fever in the territories of these regions. Analysis of our data, as well as statistics of the morbidity rate of West Nile fever in the Volgograd and Rostov regions and Dagestan confirm endemic and expanding foci of this infection in the southern regions of Russia, currently including Astrakhan, Volgograd, Rostov, Saratov, Krasnodar and Stavropol regions and Dagestan. The most active and stable foci are located on the territory of Astrakhan, Volgograd and Rostov regions.

On the basis of author's graphical analysis method, the typification of lake ecosystems transformation scenarios depending on the size of lakes was carried out. It was confirmed that the type of transformation depends not only on size of the lake, but also on the landscape and climatic region in which it is located. The distinctive features of lake ecosystems transformation types in the European part of Russia and in Western Siberia were analyzed and compared.

The results of a sintaxonomical study of plant communities of the Yamozero lake (the North-East of the European part of Russia) are presented. The diversity of the aquatic and helophytic vegetation of the Yamozero lake consists of 16 associations and 2 communities of 6 unions, 4 orders and 2 classes of the floristic classification: Potamogetonetea (7 associations, 2 communities), Phragmito-Magnocaricetea (9 associations). Many of described associations are widely distributed in the Central and the Eastern Europe. Some associations have the boundaries of their ranges. Some communities include 2 rare species of regional level: Isoetes setacea and Sagittaria natans.

The results of a syntaxonomical study of plant communities of the large lake Donty (North-East of the European part of Russia) are presented. The diversity of hydrophytic vegetation has been classified into 3 classes (Lemnetea, Potametea and Phragmito-Magnocaricetea), 5 orders, 8 alliances, 20 associations and 1 community. Subasso­ciation Scolochloetum festucaceae caricetosum aquatilis is new. Communities of associations Caricetum aquatilis, Equisetetum fluviatilis, Potamo—Nupharetum luteae, Potametum perfo­liati are mostly wide distributed, while these of Phragmitetum communis, Scolochloetum festucaceae ones are relatively rare as well as Lemno—Spirodeletum polyrchizae, Elodeo—Potametum alpini, Potamo—Nupharetum pumilae, Potametum praelongi and Scirpetum lacustris are very rare. Some communities contain 2 regional rare species: Scolochloa festucacea and Ranunculus lingua.
