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.

Results of a syntaxonomical study of the plant com­munities of the large lake Syndor (North-East of the European part of Russia) are presented. The diversity of hydrophytic vegetation has been classified into 2 classes (Potametea and Phragmito-Magnocaricetea), 3 orders (Potametalia, Phragmitetalia, Magnocaricetalia), 4 alliances, 11 associations, 7 variants and 2 communities. Association Nupharetum spenne­rianae is new. Floristic peculiarities of the lake Syndor macrophytic communities are shown. They differ from the similar communities in other regions of Russia by the absence of pleustophytic species.

The paper presents the results of the research on the growth, development, and biochemical evaluation of introduced Pyrethrum majus plants in the middle taiga subzone of the Komi Republic. It is established that in the conditions of culture the species is characterized by a high stability and winter hardiness. The phenology and dynamics of plant growth were studied. Morphological parameters of vegetative and generative shoots were determined. The yield of essential oil from the aboveground phytomass of P. majus and its component composition were studied. It was found that the content of essential oil of flowering plants varied over the years of research from 0,25 to 1,41% and depended on the weather conditions of the growing season. More than 190 components were found in the essential oil of P. majus plants using the method of GLC analysis, 48 of them were identified. The main terpenoids in the essential oil were S-(+) carvone (5465%), -tuyon (610%), TRANS-and CIS-p-Menta-2,8-dienols (2,32,8%), 1,8-Cineol (1,42,9%), CIS Menta-1(7)8-Dien-2ol (1,52,1%), germacrene d (1,21,8%) -cadinol (0,51,5%), -muurolol (0,22,6%). It was found that the component composition of the essential oil from perennial plants P. majus corresponds to the carvone-Tuyon chemotype and did not change significantly due to the meteorological conditions of the environment. Taking into account a high adaptation of plants of this species to the conditions of the middle taiga subzone of the Komi Republic, high indicators of aboveground phytomass with a sufficient content of essential oil, P. majus can be successfully cultivated in the North as a promising spicy-aromatic medicinal and ornamental plant.

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.

Abstract Background The peculiarity of Siberian fir ( Abies sibirica Ledeb.) growth in the territory of the North-East of the European part of Russia is that its habitats are confined to certain types of landscapes, namely floodplains of streams and rivers, slopes, and watersheds. In the structure of plant communities formed in such areas, fir is generally the predominant species. The purpose of this study is to find out causes why fir tree have been successful in colonizing specific types of landscapes. The study was conducted in the Komi Republic, Russia. The objects of the study were chosen two forest phytocoenoses with fir dominance, one of which grows on a slope and the other — on a floodplain terrace. A comparative analysis of the complex of factors determining the growth and development of these forest communities was made.Results Orographic conditions have been recognized as the main factor determining the species structure of phytocoenoses in the considered landscape types. The relief features of the areas where the forest stands under consideration are located contribute to the development of periodic water flows that have a significant impact on the species structure formation. Comparison of morphological and phenological features of the main forest-forming species of the Komi Republic has shown that the fir has a number of advantages contributing to its success under the conditions of a specific hydrological regime. Conclusions The formation of spatial patterns with Siberian fir dominating on slopes and floodplains is a consequence of fir adaptability to the influence of periodic water flow due to the relief features.
