A total of 7 associations, 2 subassociations, 1 variant, and 1 community type are described, of which one association (Hamatocauli vernicosae–Caricetum lasiocarpae) and 2 subassociations (Telypterido palustris–Betuletum pubescentis inops and Thelypteridetum palustris brachythecietosum mildeanae) are introduced as new ones. Communities are assigned to 4 alliances of 3 orders and 2 classes. The class Alnetea glutinosae Br.-Bl. et Tx. ex Weshoff et al. 1946 of coniferous and small-leaved forests of Eurasia includes the order Calamagrostio purpureae–Piceetalia obovatae Lapshina 2010 combining forest-like swamp communities with dark coniferous species in the tree layer, called “sogra” in Siberia, with two associations within 2 alliances in the study area.

The unique psammophytic flora makes an important contribution to the regions’ biological diversity. From the syntaxonomical point of view, psammophytic vegetation of south-east European part of Russia still poorly explored. The Sarykum sand massif is a unique object, due to its location in piedmonts of the Caucasus at a considerable distance from vast sands of Terek-Kum and Caspian lowlands (Fig. 1, 2). Our study presents the results of the analysis of 66 relevés. The data set was stored and processed in IBIS 7.2 software. As a result of performing hierarchical cluster analysis using Ward’s method, dendrogram was constructed reflecting the similarity of the relevés. Sokal/Sneath coefficient No. 1 which considers positive and negative species concurrences was used. Cluster analysis made it possible to reveal general differentiation patterns in psammophytic vegetation (Fig. 3). As a result, the relevés set was divided into two clusters differing in 28 species (Table 1). Cluster A represents poor of species and sparse communities on not fixed sands — in average 9 species per relevé and 18 % of the plants cover. Cluster B includes coenoses of fixed sands, with an average richness of 23 species and cover of 27 %. The studied communities belong to the class Festucetea vaginatae Soó ex Vicherek 1972, which represents the sandy steppes. It is distributed in the forest-steppe and steppe zones of Eastern and South-Eastern Europe, as well as in the south of Western Siberia and Northern Kazakhstan. The class includes the only order Festucetalia vaginatae Soó 1957. Psammophytic vegetation described from various regions of southern Russia belongs to the alliance Festucion beckeri Vicherek 1972, but none of its diagnostic species was noted in relevés. Comparison of our data with the associations described in the class on the territory of Russia and Ukraine allowed us to identify a group of species differentiating the psammophytic vegetation of the Sarykum massif: Artemisia tschernieviana, Astragalus brachylobus, Asperula diminuta, Centaurea arenaria, Syrenia siliculosa, Thesium maritimum, Tragopogon dasyrhynchus ssp. daghestanicus. These species can become the basis for the diagnosis of a new alliance. Its definition will be possible as a result of comparative analysis of psammophytic vegetation of the southeast of European Russia, primarily of the Caspian and Terek-Kum sands. Аss.

Kipriyanova","doi":"10.31111/vegrus/2023.46.18","DOIUrl":"https://doi.org/10.31111/vegrus/2023.46.18","url":null,"abstract":"In the framework of the project “Classification of Vegetation of the Russian Federation” (Plugatar et al., 2020; Kipriyanova et al., 2021), a revision of the modern coenotic diversity of Russia, including aquatic vegetation, is being carried out. It turned out that the types of some plant communities have not yet been described, including the association with the dominance of the Ranunculus mongolicus (Krylov) Serg. Ranunculus mongolicus was first reported in the Flora of West Siberia (Flora..., 1931) by P. N. Krylov as a subspecies of the water buttercup R. aquatilis ssp. mongolicus Kryl. (Krylov, 1931), L. P. Sergievskaya raised the taxon rank to species (Sergievskaya, 1964). In the modern monographic treatment of aquatic buttercups, this taxon is given at the species rank (Wiegleb et al., 2017). It indicates that Ranunculus mongolicus is habitually similar to R. aquatilis, although smaller in all parts. Lamellar leaves are deeply dissected, peduncles are long, all parts of the plant are densely hairy. In arid regions, it behaves like an annual (Wiegleb et al., 2017). In the course of expedition work in 2020 in the Ulagan district of the Republic of Altai, five geobotanical descriptions of communities dominated by the Mongolian buttercup (see Table) were performed, and it was decided to describe a new association. The classification was carried out on the principles of the ecological-floristic approach of J. Braun-Blanquet in accordance with the Code of Phytosociological Nomenclature (Theurillat et al., 2021). Ass. Ranunculetum mongolici ass. nov. unites the communities dominated by the Mongolian buttercup (Fig. 1, 2). The diagnostic species is Ranunculus mongolicus (= Batrachium mongolicum (Krylov) Krecz.). Nomenclature type of association (holotypus hoc loco) — relevé No 5 in the Table.

We attributed the new association to the alliance Batrachion aquatilis Passarge 1964 of the order Callitricho hamulatae–Ranunculetalia aquatilis Passarge ex Theurillat in Theurillat et al. 2015 of the class Potamogetonetea Klika in Klika et Novák 1941. The range of the community apparently coincides with the range of the species. In Asia, R. mongolicus is found in Siberia, the Russian Far East, Kyrgyzstan, Afghanistan, Mongolia, China, and Nepal (Wiegleb et al., 2017). It is found along the west coast of North America where it is confused with R. aquatilis (as R. aquatilis var. aquatilis and R. aquatilis var. hispidulus); likewise, most South American “R. aquatilis” refers to R. mongolicus. (Wiegleb et al., 2017). In Eastern Siberia, R. mongolicus is rare and does not form communities (Chepinoga, 2015). In addition to the Mongolian buttercup communities from Ulagan district, there are publicly available photographs of cenoses with R. mongolicus taken by A. I.

Arable land occupies the main part of the steppe zone, virgin steppes form small scattered patches under grazing and regular fires. Until now there was no enough information on the diversity of steppe vegetation in this region, whereas the steppe syntaxonomy of adjacent regions is rather well developed (Zhirnova, Saitov, 1993; Dubravnaya ..., 1994; Flora..., 2010; Korolyuk, 2014, 2017; Unikalnye..., 2014; Yusupova, Yamalov, 2016; Yusupova et al., 2018; Golovanov et al., 2021). The purpose of present study is to reveal the diversity of the steppes in the Southern Trans-Urals within the steppe zone and to present their classification accor­ding to Braun-Blanquet approach. The investigated area is a high foothill plain, sett­ling on the Trans-Urals peneplain. Its western border frames the foot of the Urals eastern ridges, and the eastern one adjoins the western limit of marine tertiary sediments of the West Siberian Plain. Igneous, sedimentary and metamorphic rocks of the Paleozoic prevail in geological structure, granite intrusions are widespread. Dominant soils are typical, southern and saline chernozem. The steppe zone forms latitudinal stripe of 2 degrees wide with its northern border along 54 10’ N. From the north to the south the climate becomes warmer and drier. A peculiarity of this area are numerous tiny pine, birch and aspen-birch forests forming a landscape of “false forest-steppe”. The article is based on the analysis of 286 geobotanical relevés made by authors in 2006–2021 in the southern part of Chelyabinsk Region. The classification was carried out using a modified TWINSPAN algorithm (Roleček et al., 2009) in the JUICE 7.0 package (Tichý, 2002). There are 7 associations, 1 subassociations, 5 variants and 1 community, belonging to orders Brachypodietalia pinnati (meadow steppes) and Helictotricho-Stipetalia (typical steppes) within the class Festuco-Brometea.

The environment of the fjell fields is formed due to severe microclimate and short ­growing season, thin soil layer and snow-free conditions in winter (Tolmachev, 1948). The main feature of fjell field landscape is the sparse plant cover dominated by mosses and lichens. The vegetation of fjell fields is still poorly investigated: some geobotanical relevés are available for Scandinavian Mountains (Nordhagen, 1928, 1943; Gjaerevoll, 1950, 1956), West Greenland (Sieg, Daniëls, 2005; Sieg et al., 2006, 2009; Sieg, Drees, 2007), Spitsbergen (Hadač, 1946, 1989; Eurola, 1968; Möller, 2000), and Putorana Plateau (Matveyeva, 2002). The Khibiny and Lovozero Mountains rise up to 1200 m. The vegetation of higher elevations from 840 to 1200 m was classified according to Braun-Blanquet approach in 2013–2021. Based on 90 relevés, 8 associations (5 as new ones), 2 variants and 1 community type were described (Tables 1–8) which belong to 6 alliances, 6 orders, and 6 classes. To arrange the syntaxa described in Khibiny and Lovozero Mountains in higher classification units correctly, we used the first descriptions of alliances in Fennoscandia (62 relevés) and published data of sparse vegetation in fjell fields in Spitsbergen (57 relevés).

The territory is a part of the Sokur elevation, which approaches the Salair ridge in the south-east. Common is the erosion of the landscape reflected in dense network of river valleys and draws. The vegetation is transitional between subtaiga and forest steppe (Reverdatto, 1931; Vandakurova, 1957; Kuminova, 1973; etc.). Forest meadows (the order Carici macrourae–Crepidetalia sibiricae Ermakov et al. 1999 of the class Molinio-Arrhenatheretea R. Tx. 1937) occur on the edges and glades of grassy aspen and birch forests and are an element of vegetation of both forest steppe zone and the subtaiga subzone. Their set of species and syntaxonomic diversity reflect the soil and climatic conditions of the location and may serve as a criteria for defining the zonal and subzonal borderlines. The aim of the study was to reveal and to characterize the syntaxonomic diversity of the forest meadows of the Ob-Inya watershed. The studies were conducted at the territories of the Novosibirsk, Moshkovo, and Bolotnoye districts. 114 reléves served as a basis for the study. Forest meadows are represented by 2 associations, 2 subassociations, 2 variants and 2 communities from 2 suballiances of the alliance Crepidion sibiricae Mirkin ex Ermakov et al. 1999 (Table 1). Communities of the ass. Crepidetum sibiricae Dymina ex Ermakov et al. 1999 are most common, and occur everywhere in the studied area (Table 2). The association is represented by two subassociations differing by the degree of the moisture content in the habitats.

The data are treated by IBIS 7.2 software package (Zverev, 2007). The names of the higher syntaxa follow to «Vegetation of Europe…» (Mucina et al., 2016). Synoptic tables include only species with constancy above I. Soil moisture, reaction, richness in mineral nitrogen, light, temperature and continentality are assessed using mean H. Ellenberg ecological indicator values (Ellenberg et al. 1992), hemeroby — with these of N. G. Ilminskikh ecological 9-point scale (Ilminskikh, 1993). Significant differences between pairs of syntaxa for each environmental factor are determined by the Mann-Whitney U-test in the PAST package (Hammer et al. 2001). 3 associations, 2 variants and 1 derivative community of 3 classes of vegetation are established. Ass. Chelidonio–Aceretum negundi L. Ishbirdina in L. Ishbirdina et al. 1989, var. Heracleum sosnowskyi (Table 2, Fig. 2). The association belongs to alliance Chelidonio–Acerion negundi L. Ishbirdina et A. Ishbirdin 1989, order Chelidonio–Robinietalia pseudoacaciae Jurco ex Hadač et Sofron 1980, class Robinietea Jurco ex Hadač et Sofron 1980. DS of the association are Acer negundo, Chelidonium majus, that of the variant is Heracleum sosnowskyi. Communities most often have three layers. The tree layer is dominated by Acer negundo with 7–20 m heigh and 50–90 % canopy density. The shrub layer (1–3 m, 1–50 %) is dominated by Acer negundo undergrowth, sometimes there are Padus avium, Populus alba, Prunus domestica, Sambucus nigra, S. racemosa, Ulmus glabra. The herb-d­warf shrub layer (height – 70–150 cm, plant cover – 50–100 %) is dominated by Heracleum sosnowskyi, mainly by its vegetative shoots. Generative shoots are found mainly in the most sunlit sites. There are 68 species in the association with 7–21 species per sample plot. The communities formed as a result of H. sosnowskyi penetration into phytocenoses of the var. typica ass. Chelidonio–Aceretum negundi are common in wastelands, along roads and banks of reservoirs, near abandoned houses in villages. There are slight differences in habitats of variants Heracleum sosnowskyi and typica (Fig. 3, Table 4): communities of the first one inhabit wetter soils, while these of the var. typica have the higher levels of temperature, continentality and hemerobiality, that is why there is a lot annuals and biennials, many of which are continental thermophilic species and belong to eu- and polyhemerobes (Lactuca serriola, Atriplex tatarica, Arctium tomentosumи др.). H. sosnowskyi exists even in heavily shaded areas. The species composition of communities of the var.

Lake ecosystems of the studied region are exposed to cyclical changes in accordance with the cyclicity of the hydrological regime of the lakes. Periodic fluctuations in the water level in lakes are accompanied by changes in mineralization, and therefore the biological regime of the lakes is unstable. The studies were carried out from 2001 to 2014 in Novosibirsk Region and Altai Territory. 164 complete geobotanical relevés made by the author on 80 lakes are used (Fig. 1, table 1); a list of studied lakes is given. Field work was carried out during the period of the lowest water level (summer dry season) — July–August. The following scale was used for abundance estimation: r — the species is extremely rare; + — rare, small cover; 1 — the number of individuals is large, the cover is small or individuals are sparse, but the cover is large; 2 —cover of 5–25 %; 3 — 26–50 %; 4 — 51–75 %; 5 — more than 75 %. Computer programs Turboveg for Windows 2.117 (Hennekens, Schaminée, 2001) and Juice 7.0.45 (Tichý, 2002) were used for data treatment. The syntaxonomic affiliation of phytocenoses was determined using modern literature (Bobrov, Chemeris, 2006; Vegetace…, 2011; Chepinoga, 2015; Landucci et al. 2015; Mucina, 2016). The coenotic diversity of aquatic vegetation in the studied lakes is 43 associations and 2 communities from 12 alliances, 6 orders, 5 classes (Tables 2–11). Eight associations belong to the class Lemnetea; 18 associations — Potamogetonetea; 3 associations and 2 communities — Stigeoclonietea tenuis; 9 associations — Charetea intermediae; 5 associations — Ruppietea maritimae. This rather high value of phytocenotic diversity is due to the high diversity of ecological conditions of specific lakes, in turn, determined by the different origin of lakes, the nature and composition of soils, salinity and chemical composition of waters, and temperature regime. Two new associations – Najadetum majoris ass. nov. and Ranunculetum subrigidi ass. nov. — are described. Table 10 shows the values of the frequency of associations (aquatic communities) in the lakes of the Novosibirsk region. We have identified phytocenotic complexes on the basis of data on the ranges of halotolerance of associations and in accordance with the frequency of associations in the lakes of different mineralization. Four phytocenotic complexes can be distinguished for the studied lakes of the Baraba Lowland and Kulunda Plain: freshwater, oligo-mesohaline, meso-hyperhaline, and euryhaline (Fig. 12). As for the ranges of halotoleration of lake communities, it is obvious that it is impossible to establish the universal ranges of halotolerance of species and communities of macrophytes for a number of reasons 1) regional differences in the salt composition of waters, 2)","PeriodicalId":37606,"journal":{"name":"Rastitel''nost'' Rossii","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69504210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
