Two of these (Krasnoufimskaya and Mesyagutovskaya forest-steppes) of the considerable size and are of great interest for the study of steppe and meadow-steppe vegetation diversity in the northern locations of the Cis-Urals region. In the recent decades the studies of Mesyagutovskaya forest-steppe herbaceous vegetation with their syntaxonomy were done (Yamalov, Kucherova, 2009; Yamalov et al., 2013). For Krasno­ufimskaya forest-steppe such research was not carried out. Our aim was to make the revision of previously described syntaxa on this territory using the new data and to determine their position within the class Festuco-Brometea according to modern views. Existence of the forest-steppe landscape in the forest zone of Middle Cis-Urals region is due tothebarrier effect of the Ufa Plateau, intercepting part of the rainfall coming from the Atlantic transport. The climate of the study area is continental with moderately cold winter and moderately warm summer. Bedrocks here are limestones, sandstones and slates. The extrazonal northern forest-steppe extends for two degrees in the latitudinal direction. Mountainousness increases from the north to the south, while the climate becomes drier and warmer (Table 1). The central part of Krasnoufimskaya forest-steppe is flat; its agricultural development began in 17th century, so therefore the steppe areas were preserved only on the slopes of river valleys and hills. The territory of Mesyagutovskaya forest-steppe is more mountainous, therefore, the number of preserved steppe plots here is greater than in the Krasnoufimsk area (Fig. 2, 8). The initial dataset includes 295 relevés collected in the course of the field study in 2007–2014 in some locations of the Sverdlovsk Region and the Bashkor­tostan Republic. After the revision according to EuroVegChecklist Expert System (Mucina et al., 2016) the relevés previously assigned to the class Moli­nio-Arrhenatheretea were excluded, thus the data of this paper are based on the analysis of 260 relevés. All relevés were classified using the modified TWINSPAN algorithm (Roleček et al., 2009) in JUICE 7.0 (Tichý, 2002). According to TWINSPAN results the dataset was divided into 9 groups which formed two clusters (Fig. 1). Each of them is differentiated by group of species: cluster A — by the meso-xerophyte species of meadow steppes and xeric meadows, including 18 diagnostic species of the order Brachypodietalia pinnati (syn. Brometalia erecti) (Willner et al., 2017, 2019): Amoria montana, Brachypodium pinnatum, Carex caryophyllea, Dactylis glomerata, Festuca pratensis, Lathyrus pratensis, Leucanthemum vulgare, Ranunculus polyanthemos, Trifolium pratense, Vicia cracca, etc.; cluster B — by the widespread steppe species, including diagnostic ones of the class Festuco-Brometea (Anemone sylvestris, Artemisia latifolia, Campanula sibirica, Koeleria cristata, Scabiosa ochroleuca, Sti","PeriodicalId":37606,"journal":{"name":"Rastitel''nost'' Rossii","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69502725","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}

Available geobotanical data on Desna floodplain, collected in the last 40 years, allowed identifying the main dynamic trends in the syntaxonomical space. Based on 36 relevés made by the authors in 1975–1990 previously (Bulokhov, 2001) 3 subassociations, which communities were prevalent in the Desna valley, were established: Caricetum gracilis typicum, С. g. oenanthetosum aquaticae, С. g. beckmannietosum eruciformis. As a survey of the Desna floodplain in 2015–2018 showed, both flow decrease and drop in the level of spring flood and groundwater in the XXI century have led to a change in the appearance, floristic composition, and structure of acute sedge meadows. Xerophytization of the floodplain resulted in the disappearance of the С. g. oenanthetosum aquaticae and С. g. beckmannietosum eruciformis communities. Drying of typical habitats of moist acute sedge meadows became the background of the formation of diverse communities of other types in their place. In the coenoflors of these communities changes occurred at the class level from Phragmito-Magnocaricetea Klika in Klika et Novák 1941 to Molinio-Arrhenatheretea Tx. 1937. Two groups of communities have been formed. The first group is represented by syntaxa of the alliance Magnocaricion gracilis (class Phragmito-Magnocaricetea): Caricetum gracilis typicum with variant Achillea salicifolia as well as by the communities Lythrum salicaria, Calystegia sepium, Calamagrostis canescens. The share of the alliance characteristic species in their coenofloras is 54–64%, and Carex acuta, as a rule, dominates. The second group represents the communities of wet meadows (order Molinietalia caeruleae) of the class Molinio-Arrhenatheretea. The alliance Deschampsion cespitosae is established with subass. Poo palustris–Alopecuretum pratensis typicum (with three variants: Veronica longifolia, Hierochloё odorata, Galium physocarpum) and three communities (Cirsium arvense, Lysimachia vulgaris, Stachys palustris) The share of characteristic species of the order in their coenofloras is 58–95%. All communities and variants form series along the moisture gradient in habitats of acute sedge meadows. Communities Lythrum salicaria, Calystegia sepium, Calamagrostis canescens are distributed in the wettest and richest in mineral nitrogen habitats in the Middle Desna area, in the former long-flooded low-level floodplain. The other ones occur, first of all, in the Upper and Middle Desna areas on a short- and long-flooded floodplain of an average level. These communities are forming on moist and fresh soils.

There are 430 rivers whose length exceeds 10 km within the Novosibirsk Region. The aim of our work was to study the phytocenotic diversity of their aquatic and semiaquatic vegetation. 130 geobotanical relevés were performed by the authors in July–August 2003–2005. The object was aquatic communities formed by true aquatic (submergent and floating-leaved) plants and semiaquatic ones with emergent plants and these of water′s edge. In total 10 watercourses were studied (Table 1): 2–3 in each of five geomorphologic regions within the forest-steppe zone (Table 2). The upper, middle and lower courses (Fig. 1, Table 1) with the length of 2–2.5 km were studied in each case to ensure the 4–5 repetition of main elements (stream pools and ridges) that would give a reliable information on their flora and vegetation. The sample plots were selected above the settlements, whenever possible in sites with no to intensive anthropogenic impact. The data were collected according to J. Braun-Blanquet (1964) approach. The relevés were done on the sample plot of 100 m2 placed in the most homogeneous part of the community or, in case of its smaller area, within the natural boundaries. 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 %. The date on water depth, transparency (on a white Secchi disk with a diameter of 30 cm), temperature and the flow rate were obtained. The soil mechanical composition and color, the degree and nature of anthropogenic impact on vegetation and river banks were quantified. Water samples for general chemical analysis were taken in the middle course of each river. Computer programs TURBOVEG and MEGATAB (Hennekens, 1996) were used for database. The syntaxonomic affiliation of phytocenoses was determined using modern literature (Bobrov, Chemeris, 2006; Vegetace..., 2011; Chepinoga, 2015; Landucci et al. 2015; Mucina et al., 2016, etc.). 36 associations and 3 communities belonging to 12 alliances, 9 orders, and 5 classes have been identified (Tables 3–14, Fig. 2–9). Such great syntaxonomic diversity is determined by the significant ecotopic variety, the variability of substrates, the wide range of water flow rates and the different water trophicity. For comparison, 26 associations, 13 variants, 2 communities were identified in the study of 50 rivers of Lithuania (Sinkyavichene, 1992); altogether 84 associations are known for the Upper Volga region as a whole (Bob­rov, Chemeris, 2006), while 45 ones were recorded previously in 130 watercourses of this region (Bobrov, 1999).

It is located in the transitional zone between dry and desert steppes. Vegetation of this territory is represented by steppes and meadows, as well as small patches of deciduous forests. (Fig. 2) The sand massif is located far from nearest localities of the sandy steppes to the west of the Volga River (Fig. 1). «Dyakovskiy forest» is the unique southern forest outpost in European Russia, supposedly of relict origin (Shilova, Neronov, 2010). Sandy steppes were studied in May 2018. 16 relevés were performed on 10×10 m plots. We compared the communities from «Dyakovskiy forest» with the associations of the class Festucetea vaginatae Soó ex Vicherek 1972 from the southeast of the European Russia and Ukraine. For classification and comparative analysis we used cluster analysis in the PAST software (Hammer et al., 2001). The IBIS 7.2 was used for data storage and processing (Zverev, 2007). Cluster analysis revealed differentiation patterns of psammophytic vegetation (Fig. 3). The central part of the dendrogram is occupied by sandy steppes dominated by perennial grasses (cluster 1). These communities form the prevailing plant communities in the study area; they represent the final stages of sand stabilization. Five species determine the physiognomy of the sandy steppes of the «Dyakovskiy forest»: Artemisia marschalliana, Chamaecytisus borysthenicus, Festuca beckeri, Jurinea polyclonos, Stipa borysthenica. The first cluster was divided into two groups of relevés, representing different stages of sand stabilization. The first group is characterized by high activity of bunchgrasses: Agropyron fragile, Poa bulbosa,and Stipa borysthenica. It is also indicated by the presence of common steppe plants: Allium tulipifolium, Artemisia austriaca, Carex supina, Centaurea pseudomaculosa, Eremogone biebersteinii, Galium ruthenicum, Veronica verna. The second group is distinguished by the high frequency of obligate psammophytes: Tragopogon tanaiticus, Linaria dulcis, Leymus racemosus, and Secale sylvestre. The prevalence of these species allows interpreting the second group as a stage of relatively less fixed sands. Communities with the dominance of annual plants are grouped in the right part of the dendrogram (cluster 2). Now these communities can occur only in disturbed places, for example on a plowed strips protecting «Dyakovskiy forest» from fires. One relevé represents scrub communities that inhabit relatively well-moistened depressions. Thus, the dendrogram structure reflect the main patterns in species composition, associated with sand fixation chronosequence — from stage of annual psammophytes to stage of bunchgrasses and shrubs. To determine the syntaxonomical status of sandy steppes in the system of floristic classification, the earlier described associations of the class Festucetea vaginatae were analyzed.

Syntaxonomy of this vegetation is still not clear and far from unambiguous explanation. From literature, these communities in Fennoscandiаn mountain tundra are related to several classes: Juncetea trifidi, Saliceteaherbaceae, Thlaspietea rotundifolii and Molinio-Arrhenatheretea, which differ greatly both to habitats and vegetation. In Russian phytocoenology, some researchers include tundra grasslands with dominance of Nardus stricta and Avenella flexuosa in general typology (Ramenskaya, 1958), along with floodplain and dry grasslands and meadows, but other consider such vegetation in mountain tundra as independent type, related to grasslands and meadows in alpine belt (Gorodkov, 1938; Aleksandrova, 1977).
