We studied tussock communities with Eriophorum vaginatum attributed to the class Oxycocco-Sphagnetea Br.-Bl. et Tx. ex Westhoff et al. 1946 and predefined class Carici arctisibiricae–Hylocomietea alaskani class. prov. (Matveyeva & Lavrinenko 2021) Two new associations – Ledo decumbentis–Eriophoretum vaginati Lapshina ass. nov. (with 3 variants) and Pleurozio schreberi–Eriophoretum vaginati Lavrinenko et Lavrinenko ass. nov. (with subassociations typicum, shagnetosum lenenses, and sphagnetosum russowii) have been described in the bog class. The first association is confined to the southern tundra subzone of the West Siberian sector of the Arctic, while the second one to the East European sector of the Arctic, where the subassociations alternate along a gradient from the north of the typical tundra subzone to the south of the southern tundra subzone. The new association Arctagrostio latifoliae–Eriophoretum vaginati Lavrinenko O. et Lapshina ass. nov. has been categorized as zonal tundra vegetation. We compared these associations with syntaxa of the communities with Eriophorum vaginatum that were previously described in bog and zonal positions in the Siberian Arctic and Alaska.

The development of the seed-cones of Taxus canadensis was studied. Aril is multilayered. The seed coat is multi-layered, its structure changes during development. Initially, it consists of 33–35 layers of cells, and by the time of maturation they are reduced to 10 layers. A marker sign of changes of seed-cones structure is the appearance of an aril from under the scales. At this time, there is an active thickening of the cuticle of the epidermic cells of the seed, sclerenchymatization of zone I of mesotesta cells and obliteration of zone II, differentiation of cells in the chalaza area. The nucellus is reduced, the endosperm and embryo grow, and oil droplets appear in the cells of the endosperm. A week later, even greater differentiation of cells in the chalaza area starts and a rapid growth of the aril is observed during the week.

In 2017–2020, in the territory of the Southern Urals (the Republic of Bashkortostan, Orenburg and Chelyabinsk Regions), we studied the synanthropic communities of transport routes. The syntaxonomic analysis resulted in the description of two associations of the order Agropyretalia intermedio–repentis, the class Artemisietea vulgaris, which are new both for science and the Southern Urals region: Lactucо tataricaе–Psathyrostachyetum junceae ass. nov. and Sisymbrietum volgense ass. nov. They are found in the steppe zone of the Republic of Bashkortostan, Orenburg and Chelyabinsk Regions, along the roadsides of transport routes, less often in wastelands in settlements. Communities dominated by Psathyrostachys juncea are encountered along the roadsides and slopes of highways in the southern part of the Trans–Urals region of the Republic of Bashkortostan. A characteristic feature of the communities of the association Sisymbrietum volgense is the dominance of the invasive Sisymbrium volgense, which settles actively along the transport routes throughout the entire South Urals region. The DCA ordination of the communities of the order Agropyretalia intermedio–repentis confirmed the results of the syntaxonomic analysis and demonstrated significant differences in the ecology of various cenoses by the following ecological factors: moistening, soil texture and structure, soil fertility, and the thermo-climatic factors. The described syntaxa form the most xerophytic branch of the order Agropyretalia intermedio–repentis in the Southern Urals.
2017-2020年，在南乌拉尔地区(巴什科尔托斯坦共和国、奥伦堡和车里雅宾斯克地区)，我们研究了交通路线的协同社区。通过分类学分析，获得了在科学上和乌拉尔南部地区都是新发现的Agropyretalia intermedio-repentis目Artemisietea vulgaris的两个类群:lactuctataricaaur - psathyrostachyetum junceae ass. 11和Sisymbrietum volgense ass. 11。它们分布在巴什科尔托斯坦共和国、奥伦堡和车里雅宾斯克地区的草原地带，在交通路线的路边，在荒郊野外较少发现。在巴什科尔托斯坦共和国跨乌拉尔地区南部的路边和高速公路的斜坡上，可以看到以Psathyrostachys juncea为主的社区。西西姆植物群落的一个特征是入侵西西姆植物的优势，它在整个南乌拉尔地区的交通路线上活跃地定居。通过对Agropyretalia intermedio - reentis目群落的DCA排序，证实了分类学分析的结果，并显示了不同植物群落在湿润、土壤质地与结构、土壤肥力和热气候等生态因子方面存在显著差异。本文所描述的合群构成了乌拉尔南部的Agropyretalia middle - repentis目中最旱生的分支。

This paper focuses on study of benthic diatoms of the sand beach of Kruglaya (Omega) Bay of the Black Sea. For the first time, diatom algae of epipsammon were studied in an electron scanning microscope. 14 Bacillariophyta taxa representing 8 genera were found, of which 6 species of the genus Cocconeis Ehrenberg (C. guttata, C. pinnata, C. placentula, C. pseudodebesii, C. scutellum, Cocconeis sp.) prevailed. Of the diatoms, 6 species, Anorthoneis arthus-bertrandi, A. dulcis, Cocconeis guttata, Coscinodiscus concinnus, Diplomenora cocconeiformis and Pseudostaurosira medliniae were found in Black Sea coastal waters for the first time. Original and literature data on species morphology, variability of shell and shell size, occurrence, ecology and geography of distribution in different areas of the World Ocean are presented. 55 SEM-microphotographs of all diatom species from different angles are presented.

An inventory of alien and native species of vascular plants was taken along the Trans-Siberian Railway, from the settlement of Yerofey Pavlovich to Kundur-Khabarovskiy railway station, with the total length of 1043 km (11 % of the TSR) explored. The study encompassed sixteen railway stations located in two biomes, including Amur-Zeya Boreal Taiga with variants southern taiga and subtaiga, and Zeya-Bureya Nemoral Broadleaved Forests and Forest-Steppe ones. The highest similarity was displayed by south taiga and subtaiga variants of the Amur-Zeya Boreal Taiga biome, with Sørensen’s coefficient equaling to Ks = 46 % on embankment slopes and Ks = 45 % for rail bed, while a low measure of similarity was detected in the railway right of way (Ks = 24 %). The number of railway flora species displays a strong positive correlation with average annual temperature and average annual precipitation within the biome, and a strong negative correlation with the total number of vascular plants recorded within the biome, as well as with the biome area.

The genetic diversity of 78 individuals of Rhododendron redowskianum Maxim. from five natural populations of different territories of the Far East – Magadan Region, Sakhalin Region, Primorye Territory and Northeast China was studied. Variability of the species according to five markers of plastid DNA was very low. The only one mutation was detected in one of the markers in a singl individual from Sikhote-Alin population. Analysis of the polymorphism of eight nuclear microsatellites, on the contrary, revealed a high level of diversity in all samples (mean values: Aa = 6.44, Ae = 4.43, Ho = 0.514, He = 0.523) and high interpopulation differentiation (FST = 0.299, p < 0.001). Population structure analysis identified four genetic clusters that correspond to the four geographic areas represented. Relationship analysis based on plastid DNA data revealed the ancestral position of R. redowskianum in relation to the closely related species R. camtschaticum Pall. s.l.

The pollution of environment by toxic heavy metals has increased dramatically over the past decades due to various sources of contamination, mainly industrial and human activities. Soil is the main recipient of air and water contamination. In this study, we evaluated the ability of radish plants to accumulate chromium VI (Cr(VI)) (150 ppm) under the application of citric acid (CA) (15 mM). The results showed that Cr(VI) reduced shoot dry weight, root dry weight, hypocotyl dry weight, and total chlorophyll content. On the other hand, Cr(VI) increased H2O2, malondialdehyde, and antioxidant activities of the radish plant. However, the application of CA improved the growth and physiological parameters and antioxidant content (superoxide dismutase 5 % and 4 %, peroxidase content 24 % and 4.25 %, catalase 38 % and 28 %, and ascorbate peroxidase 4 % and 35 %) in root and shoot part respectively, and increases the accumulation of Cr(VI) in different parts of the radish plant.

The chromosome numbers (2n) are presented for 82 vascular plant species of 61 genera from 31 families: Amaranthaceae: Amaranthus, Atriplex; Apiaceae: Angelica, Pimpinella, Torilis; Araceae: Calla; Asteraceae: Bidens, Hieracium, Lactuca, Leontodon, Solidago; Boraginaceae: Cerinthe, Lappula; Brassicaceae: Fibigia; Campanulaceae: Platycodon; Caryophyllaceae: Dianthus, Eremogone; Cupressaceae: Cupressus; Ericaceae: Rhododendron; Euphorbiaceae: Euphorbia; Fabaceae: Acacia, Astragalus, Galega, Lotus, Robinia, Trifolium, Vicia; Grossulariaceae: Ribes; Iridaceae: Iris; Lamiaceae: Leonurus, Lycopus; Liliaceae: Lilium; Nelumbonaceae: Nelumbo; Onagraceae: Chamaenerion; Orobanchaceae: Pedicularis; Paeoniaceae: Paeonia; Papaveraceae: Chelidonium, Glaucium, Papaver; Plantaginaceae: Plantago; Poaceae: Achnatherum, Calamagrostis, Digitaria, Eragrostis, Glyceria, Milium, Phleum, Poa, Puccinellia; Polygonaceae: Persicaria, Rumex; Primulaceae: Anagallis; Ranunculaceae: Delphinium, Pulsatilla; Rosaceae: Potentilla, Sibbaldia, Spiraea; Rubiaceae: Asperula; Urticaceae: Parietaria; Valerianaceae: Valeriana; Violaceae: Viola. The species studied are from East Europe (Ukraine), Siberia (Irkutsk Region, Novosibirsk Region, Republic of Buryatia), Caucasus (Abkhazia, Armenia, Azerbaijan, Georgia, Russia), Middle Asia (Kazakhstan, Kyrgyzstan, Turkmenistan, Uzbekistan) and the Russian Far East (Amur Region, Khabarovsk Territory, Primorye Territory). Most of the species are diploids, with different basic numbers (x). Species with variable ploidy also were revealed. The CN data are accompanied with the brief information on ecology and distribution of the species studied.
