The psammophytic communities on sandy accumulative coasts of the Black and Azov Seas were studied in the Krasnodar Territory (Russia) in 2004, 2006 and 2009, when 1610 relevés were made. Of these, 203 relevés were previously classified and published. In this paper based on 23 relevés two new associations and two new subassociations of the class Ammophiletea Br.-Bl. et Tx. ex Westhoff et al. 1946 and one rankless transitional community (Fig. 1) are described according to Braun-Blanquet approach. The abundance of plants estimated in the field as a percentage of the projective cover was converted to scale points: 5 — > 50 %, 4 — 26–50 %, 3 — 16–25 %, 2 — 6–15 %, 1 — 1–5 %, + — < 1 %. Clustering of the relevés (phytocenon isolation) was carried out by flexible beta linkage (β = –0.25) based on the Sørensen coefficient in PC-ORD 5.0, available through the JUICE 7.1 software package (Tichý, Jason, 2006). As a result four phytocenons were established. Their species composition was compared with the species lists of the lower 676 coastal syntaxa of the Azov-Black Sea region, taken from literature and stored in authors’ syntaxon database (GIVD ID EU-RU-005) based on the TURBOVEG program (Hennekens, Schaminée, 2001). An initial assessment of the similarity of littoral syntaxa and phytocenons was performed using several methods available in the JUICE 7.1 software package. In all cases bryophytes and lichens as well as vascular plant species with frequency less than 20 % in any community were excluded from the analysis. All these excluded species are present in Tables 1 and 2. To classify the established phytocenons, their species composition was compared with similar protologues of the lower syntaxa (Table 1). The vascular plant taxa names are by Tutin et al., (2001). In naming the taxa below, a broad understanding of species (s. l.), their aggregation (agg.), or the combination of several species (with “+”) are used: Artemisia campestris+A. tschernieviana, Cakile maritima s. l. (C. maritima, C. maritima subsp. euxina), Centaurea arenaria s. l.(C. arenaria, C. arenaria subsp. odessana), Leymus racemosus s. l. (L. racemosus, L. racemosus subsp. sabulosus); S. kali aggr. (Salsola kali, S. kali subsp. ruthenica or S. kali subsp. tragus) based on P. Uotila (2011) and S. L. Mosyakin (2017); Xanthium strumarium s. l. (X. strumarium, X. strumarium subsp. italicum, X. strumarium subsp. strumarium × subsp. italicum). Few bryophyte and lichen taxa are given with their authors. The names of the new syntaxa are formed according to the ICPN rules (Theurillat et al., 2021). The terrain in the study area is flat.

The tendency to gradual reduction of crop is observed now in the North-West of the Russian Federation. From 2010 for 2021 the total area under crops in four regions (Leningrad, Novgorod, Pskov, Vologda) has decreased from 1150.7 to 907.5 thousand hectares. Studies of specific structure of weed communities of the North-West of the Russian Federation started in the first decade of the XX century with inspections of crops by A. I. Maltsev in the St. Petersburg region (Maltsev, 1908, 1909). Since the beginning of the XXI the study of weed plants were focused at the All-Russian Institute of Plant Protectionwhere monitoring of crops of the North-West of the Russian Federation (Mysnik, 2012; Luneva, Mysnik, 2016, 2017, Luneva et al., 2009) has became the priority direction. In spite of previous wide floristic researches, the diversity of weed communities of this region is still not established. The first results of the floristic classification of weed vegetation in the North-East of the Russian Federation are presented. The dataset is based on 278 relevés made by N. N. Luneva, I. N. Nadtochiy, E. V. Filippova, T. D. Sokolova, Yu. V. Eroshina for field seasons in 1999–2916. The research area covered Leningrad, Novgorod, Pskov and Vologda regions. Data processing was carried out according floristic classification approach (Westhoff, Maarel, 1978), using TWINSPAN algoritm in JUICE software packages (Tichy, 2002). The new syntaxa are named in accordance with the rules of the International Code of Phytosociological Nomenclature (Theurillat et al., 2021). DCA-ordination using the CANOCO 4.5 software package (Ter Braak, Smilauer, 2002) was produced to identify patterns of environmental differentiation. The habitat moisture and soil richness-salinity scales status of communities (Ramenskiy et al., 1956) was calculated and basic agroclimatic parameters were identified to characterize the ecological variability of habitats. The communities were classified within the order of Aperetalia spica-venti J. Tx. et Tx. in Malato-Beliz et al. 1960 of the class Papaveretea rhoeadis S. Brulo et al. 2001 and were assigned to the alliance Scleranthion annui (Kruseman et Vlieger 1939) Sissingh in Westhoff et al. 1946), which unites the most mesophytic weed communities distributed mainly on gray forest, sod-podzolic, podzolic and other types of soils of the forest zone. The alliance diagnostic species are Stellaria media, Tripleurospermum inodorum, Capsella bursa-pastoris, Lepidotheca suaveolens, Thlaspi arvense, Centaurea cyanus. Three species from the diagnostic groups of ruderal vegetation classes are also active in their cenoflora — Elytrigia repens, Viola arvensis, Taraxacum officinale. From the diagnostic group of the Papaveretea rhoeadis class and the order Aperetalia spica-venti with high constancy, species are found Cirsium setosum, Chenopodium album, Sonchus arvensis, less often are Fallopia convolvulus. The group of species of the alliance Scleranthion annui inclu
现在在俄罗斯联邦的西北部可以观察到作物逐渐减少的趋势。从2010年到2021年，四个地区(列宁格勒、诺夫哥罗德、普斯科夫、沃洛格达)的作物种植总面积从1150.7万公顷减少到90.75万公顷。俄罗斯联邦西北部杂草群落特定结构的研究始于20世纪头十年，由A. I. Maltsev在圣彼得堡地区对作物进行考察(Maltsev, 1908, 1909)。自21世纪初以来，杂草植物的研究集中在全俄植物保护研究所，该研究所监测俄罗斯联邦西北部的作物(Mysnik, 2012;Luneva, Mysnik, 2016, 2017, Luneva et al.， 2009)已成为优先方向。尽管已有广泛的植物区系研究，但该地区杂草群落的多样性尚未建立。本文介绍了俄罗斯联邦东北部杂草植被区系分类的初步结果。该数据集基于N.

Classification of dark coniferous forests of the Eastern part of Europe, Southern Urals and Western Siberia was performed using data set of 55 low-rank syntaxa (association, subassociation and variant), results of cluster analysis (Ward method, Euclidian distance) and DCA ordination (Fig. 1, 2). The synoptic table of dark coniferous forests syntaxa (Table) was developed and clarification of their diagnostic features was made. In accordance with the “Vegetation of Europe ….” (Mucina et al., 2016), the entire diversity of the higher units of the dark coniferous forests was classified into two classes, two orders and eight alliances. At the highest hierarchical level, two classes were clearly distinguished — the Asaro europaei–Abietetea sibiricae Ermakov et al. in Willner et al. 2016 and Vaccinio-Piceetea Br.-Bl. in Br. Bl. et al. 1939. The class Asaro europaei–Abietetea sibiricae includes subnemoral dark coniferous forests occurring in southern part of forest zone in the Southern Urals and Western Siberia. These forests combine some important features of boreal and nemoral vegetation in the phytocoenotic structure (physiognomy) and floristic composition. Therefore, the diagnosis of the class Asaro europaei–Abietetea sibiricae is based on a combination of the following criteria. 1. The absolute predominance of cold-resistant boreal tree species (Picea obovata, Pinus sibirica, Abies sibirica) in the higher layer makes it impossible to assign them to the higher units of nemoral vegetation and fundamentally distinguishes them from the class Carpino–Fagetea sylvaticae Jakucs ex Passarge 1968. 2. The high constancy values of widespread Eurasian shade-tolerant species associated dominantly with dark coniferous forests: Dryopteris expansa, D. carthusiana, D. assimilis, D. dilatata, Phegopteris connectilis, Diplazium sibiricum, Gymnocarpium dryopteris, G. robertianum, Athyrium filix-femina, Oxalis acetosella, widespread European-Siberian nemoral species: Daphne mezereum, Dryopteris filix-mas, Viburnum opulus, Stachys sylvatica, Galium odoratum, Geranium robertianum, Festuca altissima, Asarum europaeum, Actaea spicata, Brachypodium sylvaticum, Aegopodium podagraria, Viola mirabilis, Sanicula europaea, Festuca gigantea, as well as nemoral species with narrower ranges located in southern Siberia: Osmorhiza aristata, Anemonoides altaica, Corydalis bracteata, Erythronium sibiricum, Anemonoides caerulea, Myosotis krylovii, Euphorbia Pilosa and European species with eastern boundaries of ranges running in the southern Urals: Ulmus glabra, Pulmonaria obscura, Polygonatum multiflorum, Cicerbita uralensis, Geum urbanum, Carex pilosa, Euonymus verrucose. All these species were included in diagnostic combination of the Asaro europaei–Abietetea sibiricae. 4.

The high constancy values of widespread Eurasian shade-tolerant species associated dominantly with dark coniferous forests: Dryopteris expansa, D. carthusiana, D. assimilis, D. dilatata, Phegopteris connectilis, Diplazium sibiricum, Gymnocarpium dryopteris, G. robertianum, Athyrium filix-femina, Oxalis acetosella, widespread European-Siberian nemoral species: Daphne mezereum, Dryopteris filix-mas, Viburnum opulus, Stachys sylvatica, Galium odoratum, Geranium robertianum, Festuca altissima, Asarum europaeum, Actaea spicata, Brachypodium sylvaticum, Aegopodium podagraria, Viola mirabilis, Sanicula europaea, Festuca gigantea, as well as nemoral species with narrower ranges located in southern Siberia: Osmorhiza aristata, Anemonoides altaica, Corydalis bracteata, Erythronium sibiricum, Anemonoides caerulea, Myosotis krylovii, Euphorbia Pilosa and European species with eastern boundaries of ranges running in the southern Urals: Ulmus glabra, Pulmonaria obscura, Polygonatum multiflorum, Cicerbita uralensis, Geum urbanum, Carex pilosa, Euonymus verrucose. All these species were included in diagnostic combination of the Asaro europaei–Abietetea sibiricae. 4.

The article provides a survey of grass psammophylous vegetation syntaxa in the Southern Nechernozemye of Russia and validation of syntaxa in accordance with the requirements of the International Code of Phytosociological Nomenclature (Theurillat et al., 2021); questions of syntaxonomy and diagnosis of units of different levels of the syntaxonomical hierarchy are discussed. The data for the analysis was the base obtained in 2018–2021, including 312 relevés of psammophylous grass vegetation in the Southern Nechernozemye of Russia (Bryansk, Kaluga, south-west of Moscow, north-west of Oryol, Smolensk Regions). Most of the relevés were made on the watershed of two large river systems: the Dnieper (the Sozh river basin) and the Volga (the Oka river basin) while some ones are in the northwestern part of the Smolensk region (Demidovsky district, Smolenskoye Poozerye National Park), which belongs to the Zapadnaya Dvina basin. Natural psammophytic habitats in this region are widespread on outwash plains, sandy river terraces dominated by pine forests of the alliance Dicrano–Pinion sylvestris (Libb. 1933) W. Mat. 1962 nom. conserv. propos. Open sands are formed in the place of such forests after clear felling of pine with the destruction of the living land cover. In addition, psammophylous grass vegetation forms on non-flooded or short-flooded sandy ridges in river floodplains, on plowed sands that were opened during construction, along sand pits, on clearings under power lines, along old abandoned roads on sand embankments and sandy roads fallow lands and pastures with sandy and sandy loam soils (Kupreev et al., 2020). The psammophylous grass vegetation of the studied region is represented by 12 associations comprising 4 alliances and 2 orders of the class Koelerio–Corynephoretea canescentis Klika in Klika et Novák 1941, which unites dry grasslands on sandy soils and on rocky outcrops of the temperate to boreal zones of Europe, the North Atlantic islands and Greenland (Mucina et al., 2016). On the basis of comparative analysis for alliances and orders we compiled regional combinations of diagnostic species with constancy in coenoflora above 20 % and values of the statistical φ-coefficient above 20 (at p <0.01): Armerion elongatae (Armeria maritima, Astragalus arenarius, Dianthus fisheri, Jovibarba globifera, Jurinea cyanoides, Koeleria glauca), Corynephorion canesentis (Corynephorus canescens), Hyperico perforati–Scleranthion perennis (Berteroa incana, Festuca ovina, Helichrysum arenarium, Hypericum perforatum, Jasione montana, Pilosella officinarum, Rumex acetosella, Scleranthus perennis, Trifolium arvense). The following species diagnose the orders of psammophylous vegetation: Corynephoretalia canescentis (Chamaecytisus ruthenicus, Cladonia arbuscula, Corynephorus canescens, Jurinea cyanoides, Koeleria glauca, Sedum acre) and Trifolio arvensis–Festucetalia ovinae (Abietinella abietina, Elytrigia repens, Hieracium umbellatum, Jasione montana, Festuca ov
本文对俄罗斯南部Nechernozemye的禾草沙生植被句法进行了调查，并根据《国际植物社会学命名法》的要求对句法进行了验证(Theurillat et al.， 2021);讨论了句法层次中不同层次单位的句法分类学和诊断问题。用于分析的数据是2018-2021年获得的基础数据，包括俄罗斯南部涅切尔诺泽耶(布良斯克，卡卢加，莫斯科西南部，奥廖尔西北部，斯摩棱斯克地区)的312个沙门草植被的相关数据。大多数相关的调查都是在两大河流系统的分水岭上进行的:第聂伯河(Sozh河流域)和伏尔加河(Oka河流域)，而一些调查则是在斯摩棱斯克地区的西北部(Demidovsky区，斯摩棱斯克普泽耶国家公园)，该地区属于Zapadnaya Dvina盆地。该地区的天然沙生植物栖息地广泛分布于外冲平原和沙质河流阶地上，主要是联盟Dicrano-Pinion sylvestris的松林(Libb. 1933) W. Mat. 1962。言之凿凿。开阔的沙地是在松树被砍伐殆尽、生物覆盖被破坏后形成的。此外，沙生草植被形成于河流洪泛区未淹水或短淹水的沙质山脊、施工期间开垦的犁耕沙地、沙坑、电线杆下的空地、沙质堤防和沙质道路上的废弃旧路、休耕地和含沙质和沙质壤土的牧场(Kupreev et al.， 2020)。研究区域的沙生草植被由Klika et Novák 1941中的Koelerio-Corynephoretea canescentis Klika类的4个联盟和2个目组成的12个协会代表，它将欧洲温带至寒带、北大西洋岛屿和格陵兰岛的沙质土壤和岩石露头上的干燥草地结合在一起(Mucina et al.， 2016)。在对联盟和目数进行比较分析的基础上，编制了群落稳定性在20%以上、φ-统计系数大于20 (p <0.01)的诊断种区域组合;长青蒿(海洋蒿、沙棘黄芪、石竹、金盏花、金盏花、金盏花)、长青蒿(沙青蒿、羊蹄蒿、沙青菊、穿孔连翘、蒙大拿连翘、毛茛、牛蒡、二年生连翘、三叶草)。属沙生植物目的植物有:长尾草(Chamaecytisus ruthenicus, Cladonia arbuscula，长尾草(corynephretalia canescens)，长尾草(Jurinea cyanoides)，青花草(Koeleria glauca)， Sedum acre)和长尾草(Trifolio arvenia ovinae) (Abietinella abietina, Elytrigia repens, Hieracium umellatum, Jasione montana，长尾草，F. rubra, Galium mollugo, Pilosella officinarum，车前草，Poa angustifolia, Trifolium arvense, Viola tricolor))。联盟的诊断组合部分重复了目的诊断组合，有些种是两个联盟的诊断组合，这与分类学的逻辑并不矛盾。通过对比表的分析发现，所有用于分析的沙生植被的syntaxa都可以根据其目前的诊断完全归属于Koelerio-Corynephoretea canescentis类(Mucina et al.， 2016)。根据Koelerio-Corynephoretea canesensis类和sedo - sccleranthetea类的诊断种比例，不能将其分为两个类群。总的来说，在俄罗斯南部的Nechernozemye，几乎没有中欧sedo - sccleranthetea类群落的典型自然栖息地。它们被人为的生态环境所模仿，这些生态环境被冲刷或践踏，通常是受到严重干扰的碎石基质。在铁路和公路的斜坡上，在杂草丛生的石堆上，由于践踏或车辆的通过而被强烈压实，可能有可能将某些类型的草群落分类为sedo - sccleranthetea类。然而，将这些社区分配给这门课是有争议的。所研究的植物群落中有很大一部分被划分为Koelerio-Corynephoretea canescentis纲内的7个非等级单位——“群落”。首先，在演替的初始阶段，它们是先驱群落，通常是稀疏的或在区系上不完整的沙质群落，有广泛的草嗜沙质寡养生物的参与。其次，这些植物群落是在沙质和砂壤土松林的休耕地和空地等沙质植被受到人为干扰后形成的单优势植物群落;火过后，践踏。 本文对俄罗斯南部Nechernozemye的禾草沙生植被句法进行了调查，并根据《国际植物社会学命名法》的要求对句法进行了验证(Theurillat et al.， 2021);讨论了句法层次中不同层次单位的句法分类学和诊断问题。用于分析的数据是2018-2021年获得的基础数据，包括俄罗斯南部涅切尔诺泽耶(布良斯克，卡卢加，莫斯科西南部，奥廖尔西北部，斯摩棱斯克地区)的312个沙门草植被的相关数据。大多数相关的调查都是在两大河流系统的分水岭上进行的:第聂伯河(Sozh河流域)和伏尔加河(Oka河流域)，而一些调查则是在斯摩棱斯克地区的西北部(Demidovsky区，斯摩棱斯克普泽耶国家公园)，该地区属于Zapadnaya Dvina盆地。该地区的天然沙生植物栖息地广泛分布于外冲平原和沙质河流阶地上，主要是联盟Dicrano-Pinion sylvestris的松林(Libb. 1933) W.

Relevés of communities (94 in total) with shrub willows — Salix glauca, S. lanata, S. phylicifolia, and tree-like willows — S. viminalis, S. dasyclados were made in the Bolshezemelskaya tundra (11 sites, Fig. 1). Six new associations and one community type are described in 2 alliances — Polemonio acutiflorum–Salicion glaucae Lavrinenko et Lavrinenko 2021 and Galio borealis–Salicion viminalis all. nov. (Tables 1–4). The alliance Polemonio acutiflorum–Salicion glaucae unites herb and herb-moss willow scrubs (predominantly with Salix glauca, S. lanata) in lakeside depressions, runoff troughs, the slopes of hills on watersheds, slopes of bedrock terraces, above-floodplain terraces and occasionally flooded floodplains in river valleys. The range of this alliance is the plain tundra in the East European and Siberian sectors of the Arctic. Associations Polemonio acutiflorum–Salicetum lanatae Zanokha ex Lavrinenko et Lavrinenko 2021, Triseto sibirici–Salicetum glaucae Lavrinenko et Lavrinenko 2021 and Climacio dendroidis–Salicetum lanatae Lavrinenko et Lavrinenko 2021 were earlier described on Taymyr Peninsula, Kolguev and Vaygach Islands (Lavrinenko, Lavrinenko, 2021).

According to the Braun-Blanquet approach the segetal communities of rice agrocenoses of Eurasia belong to the class Oryzetea sativae Miyawaki 1960, although there is a lot of species that are diagnostic of different classes — Phragmito-Magnocaricetea Klika in Klika et Novák 1941, Lemnetea O. de Bolòs et Masclans 1955, Potamogetonetea Klika in Klika et Novák 1941, Bidentetea Tx. et al. ex von Rochow 1951, etc. The largest number of the described basic syntaxa (associations, subassociations or communities) are allocated in Eastern, South-Eastern and Central Asia. Lots of new syntaxa specific to the rice fields were described in Japan (Miyawaki, 1960), Southern Thailand (Nowak et al., 2015), Central Nepal (Nowak et al., 2016), North Korea (Kolbek et al., 1996; Kolbek, Jarolímek, 2013), Tajikistan (Nowak et al., 2013), Vietnam and the Philippines (Fried et al., 2017, 2018), many of which have been assigned in the alliance Ludwigion hyssopifolio-octovalvis A. Nowak, S. Nowak, Nobis 2015, the order Cypero–Echinochloetalia oryzoidis O. de Bolòs et Masclans 1955, the class Oryzetea sativae. The rice communities described in Western (Spain, Portugal, Andorra, Italy, France, Hungary, Romania, Bulgaria) and Eastern (Ukraine, Russian Federation) Europe which differ in species composition from those in Asian regions are assigned to the alliance Oryzo sativae–Echinochloion oryzoidis O. de Bolòs et Masclans 1955 within the above order and class. The paper represents the first results of the classification based on 20 relevés of rice communities studied in 2018 in the Gudermessky and Shelkovskoy districts of the Chechen Republic, located on the northern slope of the Great Caucasian Ridge, the Chechen Plain and the Terek–Kuma Lowland. The areas under rice crop rotation are kept at an altitude of 20–35 m above sea level both in the north and in the plain part, mainly in the interfluves of the Terek and Sunzha rivers. The climate in the rice-growing areas is continental, insufficiently humid, with the very warm summers and moderately mild winters and the lot of heat and dryness in the summer months. The mean year temperature is 10.8 °C, during the growing season of rice (May–September) — 20.8 °C; the sum of effective temperatures above 15 °C is about 3100–3400 °C (Tulyakova, 1973; Ryzhykov et al., 1991); the annual amount of precipitation is 400—450 mm with less than 270 mm in summers. The largest areas on the Terek and Sunzha river interfluve are occupied by intrazonal meadow and swamp vegetation. There are two associations and one community belonging to the alliannce Oryzo sativae–Echinochloion oryzoidis have been established within study area. The associations Echinochloo–Oryzetum sativae Soó ex Ubrizsy 1948 (Table 2, rel. 1–8) and Oryzo–Cyperetum difformis Koch 1954 (Table 2, exp. 9–14) are widely distributed in rice fields in Western and Eastern Europe, while the community Setaria pumila–Oryza sativa (Table, rel. 15–20) is a new one. On cultivated lands, the

The areas under rice crop rotation are kept at an altitude of 20–35 m above sea level both in the north and in the plain part, mainly in the interfluves of the Terek and Sunzha rivers. The climate in the rice-growing areas is continental, insufficiently humid, with the very warm summers and moderately mild winters and the lot of heat and dryness in the summer months. The mean year temperature is 10.8 °C, during the growing season of rice (May–September) — 20.8 °C; the sum of effective temperatures above 15 °C is about 3100–3400 °C (Tulyakova, 1973; Ryzhykov et al., 1991); the annual amount of precipitation is 400—450 mm with less than 270 mm in summers. The largest areas on the Terek and Sunzha river interfluve are occupied by intrazonal meadow and swamp vegetation.

The All-Russian Scientific Conference “Russian geobotany: results and development prospects” was dedicated to the 100th anniversary of the Department of Geobotany of the Komarov Botanical Institute. The Conference was held September 26–30, 2022 in St. Petersburg (Proceedings…, 2022). 123 geobotanists from 25 cities of Russia participated in the Conference as well as our colleagues from Belarus, Kazakhstan, and Vietnam. The conference activity was held in three main topics: “Vegetation diversity and conservation”, “Structure and dynamics of plant communities”, “Vegetation geography and cartography”. At the plenary session and section meetings 62 oral and 56 poster presentations were presented. Three “round-table” talk sessions were held: two of them were dedicated to the problems of vegetation classification and the last — to the issues of geobotanical terminology. A significant part of the reports at the section “Diversity and protection of plant communities” was devoted to the classification of vegetation. The most part of authors used methods of floristic classification (Brown-Blanquet approach), but general analytic surveys were presented only in some works, and the rest were devoted to regional and local prodromuses of individual unions or to descriptions of lower syntaxa. A significant part of geobotanists follows the traditional principles of the Russian and Soviet school of dominant-determinant classification; the two other approaches to vegetation classification were applied in single reports: topological-ecological and geographical-genetic. Several papers have been devoted to the classification of habitat types. A significant part of vegetation studies have been carried out on the territory of protected areas: nature reserves, sanctuaries, national parks and natural landmarks: from the westernmost — Belovezhskaya Pushcha (Belarus) to the easternmost — the Bastak Reserve (Jewish Autonomous Region) and the Koryak Reserve (Kamchatka Region). Many of the reports at the section “Structure and dynamics of plant communities” concerned the study of vegetation dynamics after anthropogenic impacts, which are the main destabilizing factors of vegetation cover. Very few studies related to climate change have been presented. Several reports analyzed the demographic structure of populations. Few reports were also devoted to the statistical modelling of vegetation dynamics. The modern approach based on the functional characteristics of plants is just beginning to develop in Russian geobotany.

The classification of West Siberian mire vegetation is more or less well developed in the southern part of the forest zone (Lapshina, 2010) while in the northern part of the West Siberian Plain it has received much less study. There are only a small number of publications containing descriptions of mire types and plant communities (Pyavchenko, 1955; Boch et al., 1971; Kirpotin et al., 1995; Smagin, 2003; Neshatayev et al., 2002). This paper presents the classification results for the low-sedge vegetation of waterlogged hollows and Sphagnum lawns, within flat palsa-bogs, ombrotrophic raised bogs and transitional mire complexes, which is assigned to two alliances — Stygio–Caricion limosae Nordhagen 1943 and Scheuchzerion palustris Nordhagen ex Tx. 1937 of the class Scheuchzerio–Caricetea nigrae Tx. 1937. The classification is based on 422 relevés performed in 2004–2019 at 22 plots located between 63° and 75° N in the northern taiga, forest tundra, and southern tundra subzones of West Siberia (Fig. 1). In the most recent summary “Vegetation of Europe…” (Mucina et. al., 2016), the alliance Stygio–Caricion limosae is assigned to the order Sphagno watnstorfii–Tomentypnetalia Lapshina 2010, however this does not seem conclusive. Communities of this order are closely associated with rich fens, often spring fens fed by ground water, which does not correspond to the real conditions in which communities of this alliance are developed. Ecologically, in the current structure of the class Scheuchzetio–Caricetea nigrae (Peterka et al, 2017), the alliance Stygio–Caricion limosae has taken the true place of the alliance Rhynchosporion albae Koch 1926 (ICPN, Art. 36), which was initially unambiguously associated with the order Caricetalia nigrae Koch 1926 based on the original relevés and diagnostic species (Rhynchspora alba, Agrostis canina, sphagnum mosses of sec. Subsecunda). Therefore, we also consider the alliance Stygio–Caricion limosae belonging to the order Caricetalia nigrae, where it fits better judging by its ecological and floristic features. The differential species combination of the alliance Stygio–Caricion limosae in the northern part of West Siberia includes Carex limosa, Drosera obovata, Juncus stygius, Gymnocolea inflata, Sphagnum perfoliatum, S. platyphyllum, S. subsecundum, Utricularia minor, U. ochroleuca, Warnstorfia exannulata, and W. fluitans. Within this alliance, two new associations with subassociations have been described: Utricularo ochroleucae–Caricetum limosae and Sphagno perfoliati–Caricetum rotundatae, of which the first one occurs in the northern taiga mires, while the second one in the forest tundra and southern tundra subzones. The order Scheuchzerietalia palustris Nordhagen ex Tx. 1937 comprises ombrotrophic vegetation of Sphagnum lawns and bog hollows (Mucina et al., 2016) and currently includes the only alliance Scheuchzerion palustris.

Mesophilous broad-leaved forests predominating in south-western part of Russia were included in alliance Aceri campestris–Quercion roboris Bulokhov et Solomeshch in Bulokhov et Semenishchenkov 2015, association Fraxino excelsioris–Quercetum roboris Bulokhov et Solomeshch 2003 and three geographic subassociations. The subassociation F. e.–Q. r. typicum Bulokhov et Solomeshch 2003 in Bulokhov et Semenishchenkov 2015 unites communities occurring mainly in the broad-leaved forests zone of the Central Russian Upland. The subassociation F. e.–Q. r. stellarietosum nemori Semenishchenkov et al. 2015 occurs in the northern part of the association range in the zone of broad-leaved forests and close to the southeastern border of the hemiboreal subzone. Mesophilous broad-leaved forests occurring in the forest-steppe zone of the Central Russian Upland were included in the subass. F. e.–Q. r. crataegetosum curvisepalae Semenishchenkov in Bulokhov et Semenishchenkov 2015. The geographical distribution of the syntaxa is related to the climate continentality gradient — from the subass F. e.–Q. r. crataegetosum curvisepalae (the largest continentality indices) to the subass. F. e.–Q. r. stellarietosum nemori (the smallest continentality indices). The associations Aceri campestris–Tilietum cordatae Zaugolnova et Braslavskaya 2003 (nom. inv.) from the Kaluga and Tula Regions (Zaugolnova, Braslavskaya, 2003) and Aceri campestris–Quercetum roboris (nom. inv.) (var. Acer tataricum) described from the Voronezh Region (Starodubtseva, Khanina, 2009) were included in the association Fraxino excelsioris–Quercetum roboris after comparative syntxonomical analysis. On the basis of a comparative analysis, diagnostic combinations of subassociations were compiled, consisting of species with constancy above 20 % and values of the statistical φ-coefficient for selections above 20: F. e.–Q. r. stellarietosum nemori — Carex sylvatica (5059.9), Equisetum hyemale (2842.3), Galeobdolon luteum (10087.4), Matteucia struthiopteris (4257.7), Ranunculus cassubicus (5857.9), Stellaria nemorum (3349.6); F. e.–Q. r. crataegetosum curvisepalae — Acer tataricum (5362.0), Crataegus rhipidophylla (5964.0), Poa nemoralis (2736.9), Pyrus pyraster (3840.8), Scilla siberica (4558.4), Viola odorata (3440.5). Analysis of the differentiaal table of mesophilous broad-leaved and spruce-broad-leaved forests syntaxa made it possible to conclude that associations previously (Onyshchenko, 2009) assigned in Ukraine to alliance Scillo sibericae–Quercion roboris have a high floristic similarity with the syntaxa of Aceri campestris–Quercion roboris from the South-West of Russia, especially in the forest-steppe part of its range. Selections of three subassociations of the association Mercurialo perennis–Quercetum roboris from Ukraine floristically close to the syntaxa of alliance Querco roboris–Tilion cordatae from the South-West of Russia. In the dendrogram of cluster analysis, the compared syntaxa are grouped i

The associations Aceri campestris–Tilietum cordatae Zaugolnova et Braslavskaya 2003 (nom. inv.) from the Kaluga and Tula Regions (Zaugolnova, Braslavskaya, 2003) and Aceri campestris–Quercetum roboris (nom. inv.) (var. Acer tataricum) described from the Voronezh Region (Starodubtseva, Khanina, 2009) were included in the association Fraxino excelsioris–Quercetum roboris after comparative syntxonomical analysis. On the basis of a comparative analysis, diagnostic combinations of subassociations were compiled, consisting of species with constancy above 20 % and values of the statistical φ-coefficient for selections above 20: F. e.–Q. r. stellarietosum nemori — Carex sylvatica (5059.9), Equisetum hyemale (2842.3), Galeobdolon luteum (10087.4), Matteucia struthiopteris (4257.7), Ranunculus cassubicus (5857.9), Stellaria nemorum (3349.6); F. e.–Q. r. crataegetosum curvisepalae — Acer tataricum (5362.0), Crataegus rhipidophylla (5964.0), Poa nemoralis (2736.9), Pyrus pyraster (3840.8), Scilla siberica (4558.4), Viola odorata (3440.5). Analysis of the differentiaal table of mesophilous broad-leaved and spruce-broad-leaved forests syntaxa made it possible to conclude that associations previously (Onyshchenko, 2009) assigned in Ukraine to alliance Scillo sibericae–Quercion roboris have a high floristic similarity with the syntaxa of Aceri campestris–Quercion roboris from the South-West of Russia, especially in the forest-steppe part of its range. Selections of three subassociations of the association Mercurialo perennis–Quercetum roboris from Ukraine floristically close to the syntaxa of alliance Querco roboris–Tilion cordatae from the South-West of Russia.

A nearly circumpolar hypoarctic species Stuckenia subretusa (Hagstr.) Holub is a rare species that grows in Yakuyia in lakes and reservoirs of deltaic systems of the large rivers (Lena, Kolyma, Yana, Indigirka, Anabar) mainly north of 68° N(Bobrov, Mochalova, 2014, 2017; Egorova, 2016; Opredelitel’…, 2020). The species is listed for Taymyr Peninsula as the most common in the plain part of the southern tundra and in the forest tundra (Pospelova, Pospelov, 2007) and as rarer in the typical tundra (Polozova, Tikhomirov, 1971). In general, this is a rather rare species. Besides the Taymyr Peninsula and Yakutia it occurs in the Bolshezemelskaya tundra, in the mouth of the Yenisey River, in Chukotka Peninsula and Alaska (Yurtsev et al., 2010; Bobrov et al., 2021). Stuckenia subretusa is a critical taxon associated by some authors (Kaplan, 2008; Konspekt…, 2012) with S. vaginata (Turcz.) Holub. However, both morphological and molecular genetic differences between these taxa were shown later (Volkova et al., 2017). It was also shown that S. subretusa is found in the lower reaches and estuarine areas of the large rivers in Asia, mainly north of 68° N, in Europe — of 67°, while the northern limit of the distribution of S. vaginata in Yakutia — 64°, in Europe — 66° (Bobrov, Mochalova, 2014), therefore these species are geographically separated. In July 2021, during a geobotanical survey of the islands of the southern part of the Lena River delta, thickets of S. subretusa were found on Sasyl-Ary Isl. (Fig. 1) in a shallow flow (channel) of 2 km total length, 130–150 m width and from 4–5 cm to 1.5 m depth with a very sluggish current. The bottom substrate is silty sands. Permafrost is 2–3 m depth. Thickets of S. subretusa were found only at 4–30 cm water depths. The thickets are monospecies with projective cover from 35 to 80 % (Fig. 2). Single specimens of Tephroseris palustris (L.) Rchb. were met rarely, at 4–5 cm water depths. Part of the thickets was located on wet sand along the shallows of the channel. S. subretusa was not found on neighboring islands. Five geobotanical relevés were made within the flow according to the generally accepted methodology with georeferencing using 12-channel GPS in the WGS-84 coordinate system on sample plots of 10×10 m. The classification was carried out on the principles of the ecological-floristic approach (Westhoff, van der Maarel, 1973). Estimation of the species projective cover in Table is given according to the Brown-Blanquet scale (Becking, 1957): r — single; + — less than 1 %; 1 — 1–5 %; 2 — 6–25 %; 3 — 26–50 %; 4 — 51–75 %; 5 — 76–100 %. The syntaxon name is given in accordance with the International Code of Phytosociological Nomenclature (Theurillat et al., 2021). The described communities belong to the class Potamogetonetea Klika in Klika et Novák 1941, the order Potamogetonetalia Koch 1926, and the alliance Potamogetonion Libbert 1931. We consider these as a part of a new association. The ass. Stuckenietum
近环极地的亚北极种subretusa猪链球菌(Hagstr.)Holub是一种稀有物种，生长在雅库亚，主要生长在68°N以北的大河(Lena、Kolyma、Yana、Indigirka、Anabar)三角洲系统的湖泊和水库中(Bobrov, Mochalova, 2014, 2017;Egorova, 2016;Opredelitel’……,2020)。该物种在泰米尔半岛被列为南部冻土带平原部分和森林冻土带中最常见的物种(Pospelova, Pospelov, 2007)，而在典型冻土带中则较为罕见(Polozova, Tikhomirov, 1971)。总的来说，这是一个相当罕见的物种。除了泰米尔半岛和雅库特之外，它还出现在布尔什米亚苔原、叶尼塞河河口、楚科奇半岛和阿拉斯加(Yurtsev et al.， 2010;Bobrov et al.， 2021)。一些作者认为subretusa是一个重要的分类单元(Kaplan, 2008;Konspekt…，2012)与S. vaginata (Turcz.)Holub。然而，这些分类群之间的形态和分子遗传差异后来被显示出来(Volkova et al.， 2017)。研究还表明，S. subretusa主要分布在亚洲大河的下游和河口地区，主要分布在北纬68°以北，欧洲分布在北纬67°，而S. vaginata在雅库特分布的北纬64°，欧洲分布在北纬66°(Bobrov, Mochalova, 2014)，因此这些物种在地理上是分开的。2021年7月，在对勒拿河三角洲南部岛屿的地理植物学调查中，在Sasyl-Ary岛上发现了S. subretusa的灌木丛。(图1)在总长度为2公里，宽度为130-150米，深度为4-5厘米至1.5米的浅流(通道)中，水流非常缓慢。底部基材是粉质砂。永久冻土层深度为2-3米。仅在4 ~ 30 cm水深处发现了沙棘灌丛。这些灌丛是单一物种，投影覆盖率在35%到80%之间(图2)。Rchb。在4-5厘米的水深很少见到。部分灌木丛位于沿河道浅滩的湿沙上。在邻近的岛屿上没有发现S. subretusa。根据普遍接受的方法，在10×10 m的样地上使用WGS-84坐标系下的12通道GPS进行地理参考，在流内进行了5个地学相关的测量。分类是根据生态-区系方法的原则进行的(Westhoff, van der Maarel, 1973)。表中物种投影盖度的估计是根据Brown-Blanquet尺度(Becking, 1957)给出的:r -单一;+ -小于1%;1 - 1 - 5 %;2 - 6 - 25%;3 - 26 - 50%;4 - 51 - 75%;5 - 76 - 100%。根据《国际植物社会学命名法》(Theurillat et al.， 2021)给出句法名称。所描述的群落属于Klika et Novák 1941中的Potamogetonetea Klika纲，1926年的Potamogetonetalia Koch目和1931年的Potamogetonion Libbert联盟。我们认为这些是新协会的一部分。11 .猪臀草(Stuckenietum subretusae)。命名类型(全息图)-相关编号21-108(表，相关3).萨哈共和国(雅库特)，布伦斯基区，萨希尔-阿列克谢。，勒拿河三角洲浅水河道，水体(北纬72.35989°，东经126.41968°)，2021年7月20日。N. N. Lashchinskiy是一位作家。该协会的诊断种为亚种猪链球菌(=亚种猪链球菌)。这种联系包括猪链球菌的单种群落，有时与其他物种的单一存在。在南部地区，该物种群落的区系可能更丰富。它们在列拿河三角洲的其他地区(Nikolin等人，2017年)、卡坦噶河的泰米尔半岛(克拉斯诺亚尔斯克地区)(Pospelova, Pospelov, 2007年)以及科米共和国(Chemeris, Bobrov, 2020年)都有可靠的发现，它们的生产力为142至409克/平方米的空气干物质。总体上，种群分布范围明显与科米共和国北部、克拉斯诺亚尔斯克边疆区、俄罗斯雅库特、楚科奇自治区和美国阿拉斯加州一致。
