Ob River

Vegetation of the right bank of the Ob River in the limits of Novosibirsk area consists of southern taiga, subtaiga and forest-steppe elements. More over, in comparison with neighboring areas on the West Siberian Plain, it contains the significant amount of mountain elements (Kuminova, Vagina, Lapshina, 1963). Natural vegetation of the area belongs to the forest-steppe subzone of the West Siberian province (Il’ina, 1985). Low percentage of forest coverage is caused by anthropogenic deforestation and wide distribution of meadows (Lapshina, 1963). This is the most endangered vegetation in Novosibirsk area. Spatial vegetation structure was studied by using the model of the Ob River basin covered 184 square kilometers. Well-developed system of ravines and small creeks caused a presence of relatively large areas with very low anthropogenic impact which potentially could be the refuges of pristine zonal vegetation. Main vegetation type of this basin is forest which covered about 31% of the area. Forest diversity of model area consists of four syntaxa of association and subassociation ranks belonging to the Brachypodio pinnati–Betuletea pendulae class. Meadow vegetation is presented by five syntaxa from the Molinio-Arrhenatheretea class and mire vegetation — by two syntaxa from the Alneteae glutinosae class. Two subassociations and four variants are described for the first time. The ravine systems could be considered as low-level landscape structures which are the natural refuges with high level of biodiversity and habitats of rare and endangered species. The slope vegetation organized in ecological rows consists of three up to four syntaxa changing from the top to the ravine bottom. The Ob River Basin flora is characterized by insignificant amount of meadow steppe species, well-represented mire flora and a presence of mountain and taiga elements. The most specific floristic features are the presence of ephemeroid species, taiga species and Siberian tertiary nemoral relics (Polozhiy, Krapivkina, 1985). All these features allow us to refer the river basin vegetation to the low-mountain subtaiga type.

The West-Siberian Plain extends more than 1200 km from west to east. Its southern part is occupied by steppe and forest-steppe zones with pre-dominance of herbaceous plant communities. Steppes and xeric meadows are widespread on this territory and characterized by a high diversity and complex spatial structure. This study presents the analysis of 874 relevés describing xeric meadows and steppes of the class Festuco-Brometea from the West Siberian Plain. Numerical analysis with using of plant indicator values showed that some ecological factors, such as soil moisture, salinity and sand content are important in differentiation of grasslands. Three zonal associations form the sequence on the latitudinal gradient from 56º to 51º of northern latitude: Galatello biflorae–Calamagrostietum epigeii (xeric meadows and meadow steppes on solonetz soils in forest-steppe zone), Helictotricho desertori–Stipetum rubentis (rich bunchgrass steppes of southern part of forest-steppe zone and northern part of steppe zone), Artemisio austriacae–Stipetum capillatae (typical bunchgrass steppes of steppe zone). Zonal associations form complexes with other grasslands of Festuco-Brometeae. In forest-steppe landscapes zonal communities usually adjoined with Galio borealis–Artemisietum ponticae in more mesic habitats and with halophyte association Limonio gmelini–Phleetum phleoides. In steppe regions zonal associations make an assemblage with relatively mesic grasslands of Trommsdorffio maculatae–Stipetum pennatae and halophyte communities of Limonio gmelini–Stipetum capillatae on solonetz soils. Three associations form the sequence related with increasing of sand content in soils: Gypsophilo paniculatae–Artemisietum glaucae, Sileno borysthenicae–Cleistogenetum squarrosae, Scorzonero ensifoliae–Festucetum valesiacae. All grasslands usually are under intense grazing that cause changes in plant communities, first of all, the reduction of meso-xerophyte species diversity. The class Festuco-Brometea in the West Siberian plain is divided into two orders. The order Festucetalia valesiacae unites xeric meadows and meadow steppes in forest-steppe landscapes. The class and order are diagnosed mainly by meso-xerophyte species with wide Eurosiberian distribution: Anemone sylvestris, Artemisia glauca, A. latifolia, Astragalus danicus, Campanula sibirica, Centaurea scabiosa, Dianthus versicolor, Festuca pseudovina, Festuca valesiaca, Filipendula vulgaris, Fragaria viridis, Galium ruthenicum, Galium verum, Koeleria cristata, Medicago falcata, Phleum phleoides, Phlomoides tuberosa, Plantago urvillei, Poa angustifolia, Polygala comosa, Scabiosa ochroleuca, Seseli libanotis, Stipa capillata, Stipa pennata, Tephroseris integrifolia, Trommsdorffia maculata, Veronica spicata. This order is presented by the alliance Galatellion biflorae located to the west from the Ob River (Korolyuk, Kiprijanova, 1998). Its communities differ from others by presence of salt-tolerant species: Artemisia pontica, Artemisia rupestris, Carex caryophyllea, Galatella biflora, Inula britannica, Melampyrum cristatum, Peucedanum morisonii, Plantago maxima, Silene multiflora. To the east from the Ob River this alliance is replaced by Poo urssulensis–Artemision glaucae, in the South Urals by Festucion valesiacae. The xeric meadows of Festuco-Brometea north from forest-steppe zone are replaced by mesic meadows of Molinio-Arrhenatheretea. The order Helictotricho-Stipetalia represents the typical steppes and xeric variants of meadow steppes. Its distribution covers steppe zone and southern part of forest-steppe zone. The main part of its diagnostic combination is formed by xerophyte steppe plants: Achillea nobilis, Adonis villosa, Androsace maxima, Artemisia austriaca, Carex supina, Galatella angustissima, Helictotrichon desertorum, Jurinea multiflora, Onosma simplicissima, Oxytropis pilosa, Pilosella echioides, Potentilla bifurca, P. humifusa, Salvia stepposa, Scorzonera austriaca, Seseli ledebourii, Spiraea crenata, Stipa zalesskii, Taraxacum erythrospermum, Thymus marschallianus, Verbascum phoeniceum, Veronica incana. Three alliances form the sequence along moisture gradient: more mesic rich steppes of Helictotricho desertori–Stipion rubentis (diagnostic species: Helictotrichon desertorum, Stipa zalesskii, Thymus marschallianus, Artemisia latifolia, Filipendula vulgaris, Fragaria viridis, Phlomoides tuberosa, Plantago urvillei, Seseli libanotis, Artemisia pontica, A. rupestris, Galatella biflora, Peucedanum morisonii, Silene multiflora), typical steppes of Artemisio austriacae–Festucion valesiacae (diagnostic species: Androsace maxima, Artemisia austriaca, Carex supina, Po­ten­tilla bifurca, Scorzonera austriaca, Taraxacum erythrospermum), and dry steppes of Stipion korshinskyi Toman1969 (diagnostic species: Kochia prostrata, Krascheninnikovia ceratoides, Leymus ramosus, Phlomoides agraria, Stipa korshinskyi, Stipa lessingiana).

The Ob River basin is the last large fragment of the range of native Euro-Siberian poplar (Populus nigra, Populus alba) forests where these forests remain intact. The taiga section of the Ob River is occupied by the association Anemonidio dichotomi-Populetum nigrae Taran 1993, and the subtaiga, forest-steppe, and steppe sections are occupied by the association Equiseto hyemalis-Populetum nigrae Taran 1997. The purpose of the study is to determine the syntaxonomic status of poplar forests growing at the junction of the southern taiga and subtaiga subzones and to provide a detailed bryofloristic characterization thereof. Based on the Braun-Blanquet approach, we studied poplar forests located near the south border of the Ob River southern taiga section (Krivosheinsky district, Tomsk Oblast, Russia, surroundings of the Kaybasovo research station, 57º14′44″N, 84º11′05″E). In the forests, average species saturation by vascular plant species is 32.3 species per 100 m2, and its range is 13–56 species/100 m2. Moss flora includes 51 species. Average species saturation by mosses is 15.4 species per 100 m2, and its range is 10–21 species/100 m2. Based on the new data, total moss flora of the Ob poplar forests has increased from 73 species to 86 species and 1 variety (by 19 %), moss flora of the poplar forests of the taiga zone – from 59 species to 81 species and 1 variety (by 39 %). We identify Kaybasovo poplar forests as the new variant, Stellaria bungeana, of the subassociation Equiseto hyemalis-Populetum nigrae betuletosum pubescentis Taran 1997 (Equiseto hyemalis-Populion nigrae Taran 1997, Salicetalia purpureae Moor 1958, Salicetea purpureae Moor 1958)

The article presents an overview of published materials for the period 1963-2020, containing information on the number of larvae and juveniles of fish in different types of water bodies of the Ob River basin (Western Siberia). Data on the fish productivity of rivers and lakes of the Ob basin for steppe, forest-steppe, taiga and tundra natural zones are presented. The Ob River is the main waterway of Western Siberia. The area of the Ob River basin is 2929,000 km2, the length of the river is 3680 km. The existing pronounced differences in the nature of the relief, climate, soils, waters, vegetation of the natural zones of the Ob basin determine the features of the hydrological regime and the living conditions of hydrobionts. Accordingly, the floodplain of the Ob river with its numerous backwaters, kuryami, lakes, sorami is the main places of spawning and feeding of fish. In the course of generalization of the published materials, information was obtained on the number and features of the distribution of juvenile fish in different types of water bodies (channel pits, floodplain lakes, old trees, sores) of the Ob River basin. The results of studies on determining the fish productivity of rivers and lakes of the Ob basin of steppe, forest-steppe, taiga and tundra natural zones are analyzed.

Sayan Mountain

In South Siberian mountains floodplain steppe meadows can be found only within steppe and forest-steppe belts. In the eastern part of the Altai-Sayan mountain region (ASMR) these belts occupy large intermontane depressions, making up the submeridional range at 56–50° N (Fig. 1). The northern part of this range consists of four large depressions (the Nazarovo, North Minusinsk, Middle Minusinsk and South Minusinsk). To the north, the Nazarovo depression merges into the West Siberian plain. The southern border of the South Minusinsk depression is the West Sayan. The southern part of range includes the Turan-Uyuk and Central Tuvinian depressions. This study is based on the analysis of 260 geobotanical relevés made in the valleys of 47 rivers (21 — in Minusinsk depressions, 26 — in Tuvinian depressions). The set includes the relevés of steppe meadow of different river types (large, medium, small), located in different parts of the studied region. The typical feature of these communities is the permanent coexistence of steppe and meadow species with negligible part of meadow-steppe herbs. All steppe meadows under discussion are similar in appearance. Tall grasses, various in different associations, form a sparse upper sublayer. Depending on the intensity of use, the main part of the herbage can be located in the middle sublayer or in the bottom one. In the middle sublayer, grasses predominate (Bromopsis inermis, Poa angustifolia, Elytrigia repens). Herbs tolerant to grazing (Potentilla bifurca, Amoria repens) make up the bottom sublayer. We have revealed 6 associations of steppe meadows. Ass. Potentillo bifurcae–Poetum angustifoliae, Potentillo bifurcae–Leymetum dasystachyos, Potentillo bifurcae–Hordeetum brevisubulati are typical for Tuvinian depressions, ass. Artemisio laciniatae–Koelerietum delavignei, Trifolio pratensis–Koelerietum delavignei и Trifolio pratensis–Festucetum valesiacae — for Minusinsk ones (Table 1). The basic bioclimatic barrier of ASMR — the West Sayan divides their areas. The ordination of new associations along the gradients of moisture supply (horizontal axis) and richness-salinity of soils (vertical axis) demonstrates that areas of associations form two ranges — the Minusinsk and Tuvinian. Every association of the Minusinsk range has corresponding association of the Tuvinian range (Fig. 2). DCA-ordination (Fig. 3) and cluster analysis (Fig. 4) of syntaxa from the South Urals, West Siberia, Yakutia and new associations have detected the specificity of the last ones, so a new alliance Potentillo bifurcae–Poion angustifoliae (order Galietalia veri, class Molinio-Arrhenatheretea) has been described. It comprises steppe meadows of the Eastern part of ASMR.

Steppe Species

Pine forests of the steppe and forest-steppe zones of West-Siberian plain (Ob-Irtysh watershed) represent a unique natural phenomenon. They form anomalously large continuous forest massifs (pine forest strips) on sand deposits in ancient ravines. These forests contrast sharply with the steppe and forest-steppe surroundings, both in the set of plant communities and in species composition. Meadow communities form a narrow belt along the periphery of pine forest strips (Lashchinsky et al., 2018). The studied Kulunda and Kasmala (Fig. 1) pine forest strips are situated in the south-eastern part of West-Siberian plain (52°35′–53°25′ N and 81°10′–83°15′ E) within the forest-steppe zone (Kuminova et al., 1963; Pavlova, 1963). A data set comprising 105 relevés of meadows was classified using TWINSPAN algorithm in Juice (Tichý, 2002), and followed by manual re-arrangement. Cluster analysis of associations was used to determine the main geographical and ecological patterns in meadow vegetation (Fig. 2). Traditionally, meadows are attributed to the class Molinio-Arrhenatheretea R. Tx. 1937. In the last decades, the concept of the class Festuco-Brometea has been changed (Mucina et al., 2016; Willner et al., 2017). In the modern interpretation, the order Brometalia erecti Koch 1926 unites the most mesophytic communities of the class. In this case, the Siberian syntaxa, which previously were considered as the order Festucetalia valesiacae, and some associations of the order Galietalia veri (Molinio-Arrhenatheretea) should be referred to the order Brometalia erecti of the class Festuco-Brometea. The syntaxonomical diversity of meadow vegetation of Kulunda and Kasmala forest strips is represented by two classes, three orders, three alliances, four associations, three subassociations and one community (Table 1). Ass. Peucedano morisonii–Festucetum valesiacae Tishchenko 2018 subass. P. m.–F. v. gypsophiletosum paniculatae subass. nov. hoc loco (Table 2, holotypus — relevé 1 (mr17-071): Altai Territory, Romanovskiy district, 6 km to the W from Guseletovo village, N 52.61063°, E 81.46572°, 25.07.2017. Author — M. P. Tishchenko) unites xeric meadows on slightly saline soils, which were found only in transition between the steppe and forest-steppe zones in southern part of the surveyed territory in the southern part of Kasmala strip (Fig. 3, 1). Specific features of their composition is the high constancy of mesoxerophytic species common in meadow steppes (Artemisia dracunculus, A. glauca, Peucedanum morisonii, Spiraea crenata, Stipa pennata, Veronica spuria, etc.). Ass. Echio vulgaris–Poetum angustifoliae ass. nov. hoc loco (Table 3, holotypus — relevé 1 (mr17-027): Altai Territory, Tyumentsevskiy district, surroundings of Voznesenskiy village, N 53.21215°, E 81.72828°, 21.07.2017. Author — М. P. Tishchenko) represents the widespread xeric meadows on sandy soils at the edges of pine forest strips in the all studied territories (Fig. 3, 2, 3). These communities, which contain both meadow and steppe species, are used as pastures, so there is a lot of ruderal plants (Cynoglossum officinale, Echium vulgare, Erigeron acris, Nonea rossica, Senecio jacobaea) in diagnostic combination. Due to the different positions on moisture gradient two subassociations are distinguished: more mesic E. v.–P. a. typicum subass. nov. hoc loco (Table 3, rel. 1–18) and more xeric E. v.–P. a. caricetosum ericetorum subass. nov. hoc loco (Table 3, rel. 19–36; holotypus — relevé 20 (mr17-011): Altai Territory, Shelabolikhinskiy district, near Baturovo village, basin of the Kuchuk river, N 53.40929°, E 82.36375°, 18.07.2017. Author — М. P. Тishchenko). Ass. Campanulo bononiensis–Dactylidetum glo­meratae ass. nov. hoc loco (Table 4, rel. 1–6; holotypus — relevé 4 (mr17-104): Altai Territory, Pavlovskiy district, 6 km to the W from Kasmala village, N 53.42048°, E 83.17238°, 29.07.2017. Author — М. P. Тishchenko) unites rare forest meadows (usually secondary) of the order Carici macrourae–Crepidetalia sibiricae, which occur on the wet edges of pine and birch-pine forests (Fig. 3, 4). In low depressions on the transition between forests and wetlands (Fig. 3, 5) on slightly saline soils there are wet meadows (the order Molinietalia) of ass. Heracleo sibirici–Festucetum pratensis ass. nov. hoc loco are found (Table 4, rel. 7–17; holotypus — relevé 7 (mr17-020): Altai Territory, Rebrikhinskiy district, near Ust-Mosikha village, valley of the Kulunda river, N 53.25558°, E 81.98389°, 20.07.2017. Author — М. P. Тishchenko). The tall-grass hay meadows with high constancy of mesophytic meadow and forest plants are within this syntaxon. These habitats are indicated by the presence of halotolerant plants (Cenolophium denudatum, Hordeum brevisubulatum, Plantago cornuti, Cirsium canum, Galatella biflora). The community Agrostis gigantea–Cirsium esculentum unites grazing meadows, that are differentiated by the occurrence of Agrostis gigantea, Artemisia laciniata, Cichorium intybus, Cirsium esculentum, Melilotus dentatus, Senecio erucifolius, Sonchus arvensis (Table 4, rel. 18–21; Fig. 3, 6). The cluster analysis of the associations representing steppes and xeric meadows of the southeastern part of West Siberia revealed two important facts. All associations were clearly spitted into two clusters, which represent the classes Molinio-Arrhenatheretea and Festuco-Brometea. Within the second cluster, the associations representing the steppe meadows of Kulunda and Kasmala pine forest strips were separated. This demonstrates that these communities differ from meadows and steppes representing alliances Carici supinae–Stipion zalesskii Korolyuk 2017 all. prov., Sileno borysthenicae–Cleistogenion squarrosae Korolyuk 2017, Helictotricho desertorum–Stipion rubentis Toman 1969 and Galatellion biflorae Korolyuk 1993. This suggests the possibility to describe new high rank syntaxa for meadows on sandy soils in the forest-steppe zone on West-Siberian plain, however new data from other regions are needed.
