This article describes a method for detecting synecological optima of bryophytes and the possibility of their use in phytoindication of ecological conditions of the biotope. Bryophytes may take a significant part in plant communities, they have the ability to accumulate heavy metals, they can be used to determine the degree of the anthropogenic load and of the formation of forest communities. All this makes them excellent bioindicators, which can give an almost complete description of the plant community. But to do this it is necessary to know the environmental optima of mosses. At the moment, there are sparse data on the environmental characteristics of the bryophytes, it is not always clear how these characteristics were obtained. Currently, there are several ways to determine the environmental optima of the bryophytes based on the occurrence data and the projective cover of mosses. These methods use L.G. Ramenskiy's scales for vascular plants, these scales are extrapolated to bryophytes. Using our experience in defining synecological optima of lichen, we offer a graphical method for identifying ecological optimum of the bryophytes in which A.L. Bellegard's ecomorph scales are applied in the modification of N.M. Matveev (for the forest-steppe zone) and D.N. Tsyganov (for the coniferous-deciduous forest subzone). The essence of this method is the plotting of a graph of the quantitative characteristics of a particular moss depending on the environmental factors. For this you need to carry out phytoindication of the biotope community by using vascular plants and determine the average cover of moss or vitality of this moss

Halophytic vegetation is very rare in the forest-steppe zone. It was studied in the tract Serdobsky solonetsin the vicinity of Serdobsk (Serdobsky district, Penza region). The studies were conducted in the years 2009–2018, using the technique of geobotanical profiling. 80 trial areas were laid (35 in 2009 and 45 in 2008). Ecological and phytocenotic classification of plant communities is performed on the dominant principle. Comparison of two descriptions of vegetation with an interval of 10 years allows us to trace the transformation of halophytic vegetation after intensive anthropogenic impact (grazing and partial plowing) in different environmental conditions. The flora of Serdobsky solonets consists of 179 species of vascular plants, of which 13 species are included in the Red book of the Penza region (2013). The share of halophytic vegetation on the territory of Serdobsky solonetshas changed over 10 years: from 97.0 % to 63.8 %. Moreover, halophyte meadows occupied 67.0 % and halophyte steppes 30.0 % of the area in 2009. Now (2018) halophytic steppes make up 30.8 %, and halophytic meadows 33.0 %.The main stages of demutation of halophytic steppe and meadow vegetation were identified in various environmental conditions (meadows and steppes). The same stages of demutation were identified earlier for the South-Eastern Solonets (Neverskinsky district of the Penza region). However, a special stage of annual saline grasslands has been identified.This place requires protection due to the high level of floral and phytocenotic diversity. We offer to organize here a natural monument called “Serdobsky solonets”.

This article is devoted to study the characteristics of ecological-cenotic structure and directions of vegetation cover transformations in riparian and coastal zones of forest swamps within the forest-steppe zone (north-western part of Kharkiv Oblast, Ukraine). The survey has been conducted in 2013–2018 in the territory of the Slobozhansky National Natural Park. Plant communities were surveyed both in phanerophyte and grass biotopes types, having different genesis and degree of disturbance (from terrestrial to aquatic, from native to artificially created forest plantations). A number of regionally rare plant species were identified in their composition (Dryopteris carthusiana (Vill.) H.P.Fuchs, Majanthemum bifolium (L.) F.W.Schmidt, Calluna vulgaris (L.) Hull, Equisetum sylvaticum L., Potentilla erecta (L.) Raeusch., Rubus saxatilis L., Eriophorum angustifolium Honck., E. vaginatum L., Drosera rotundifolia L., Nymphaea candida C.Presl, Utricularia vulgaris L.) and U. minor L. – a species listed in the Red Book of Ukraine. Route and stationary techniques of field surveys were used for clarification the general features of horizontal vegetation structural organization, as well as for studying the effect of environmental factors on state and stability of plant communities. Usage of mobile GIS applications in geodata collection and their further processing in ArcMap project allowed us to develop a large-scale geobotanical map (1:1500) as an area of permanent botanical survey (1.9 ha). According to the results of phytoindication, indicators of 7 environmental edaphotop regimes in 25 plant communities studied (objects of mapping and further monitoring) have been identified. Based on the geobotanical map, integration of data on the intensity of vegetation transformation have been conducted. It was found that plant communities ІV (the highest) and III degrees of transformation cover an area more than 0.6 hectares (one third of the total plot area). These communities were occurred mainly in phanerophyte-type biotopes (aspen, willow, birch, and, partly, pine), which have been affected by pyrogenic and biogenic factors. The GIS-project created as a result of the study serves as a geo-information base that can be further improved and used to solve other applied problems.

The Tobol and the Irtysh watershed occupy the western part of West-Siberian plain. Area studied covers latitudinal band between 55° and 57° n. l. It includes the southern part of subtaiga subzone and northern part of forest-steppe zone. This territory has been used for agriculture since XVIIth century. In the middle of XXth century the local landscapes were represented by endless arable lands alternated with tiny patches of forests on the watersheds and swamps and solonchaks prevailing at lowlands. In the end of XXth century the large areas of arable lands, especially in northern part of mentioned area, were abandoned. Nowadays this area is covered by fallow meadows on different stages of demutation. Vegetation studies of the region have started in the end of XIXth century. One of the best scientific works on local grasslands was written by B. N. Gorodkov (1915). The spectrum of natural plant communities demonstrates some changes fr om south to north. These changes enclose both zonal and intrazonal vegetation. The southern part of the area studied belongs to forest-steppe zone. Its zonal vegetation is represented by small-leaved forests, grasslands (steppe meadows) and meadow steppes. Zonal vegetation of northern part — subtaiga subzone — includes only small-leaved forests. The watershed grasslands replace the cut-off forests. Intrazonal vegetation of southern part consists of various grasslands on salty soils and swamps predominated in the northern part. The border of forest-steppe and subtaiga represents a combination of zonal and intrazonal communities disturbed by man. The goal of this article is to reveal the diversity of grasslands on drained soils of mentioned area. The analysis of 151 geobotanical relevйs obtained fr om subtaiga and northern forest-steppe of Omskaya and Tyumenskaya administrative districts has been carried out. The syntaxonomy of the Tobol-and-the Irtysh watershed grasslands is represented by 6 associations, 4 subassociations and 2 communities of 4 alliances, 4 order and 2 classes. Subtaiga and northern forest steppe are charac­terized by different spectra of grasslands. This can be explained by a presence of wide range of saline soils in forest-steppe and their absence in subtaiga. The floristic composition of grasslands of forest-steppes zone includes the plants tolerant to soil salinity such as Artemisia pontica, Galatella biflora, Plantago maxi­ma, Eryngium planum, Saussurea amara, Limonium gmelinii. The listed species are rare in subtaiga grasslands while Festuca pratensis, Phleum pratense, Agrostis gigantea of alliance Festucion pratensis are dominated in subtaiga grassland meadows. Steppe meadows of this territory are represented by two classes. Northern forest-steppe subzone demonstrates the northern lim it of Festuco-Brometea (alliance Galatellion biflorae of order Festucetalia valesiacae). The associations Galatello biflorae–Calamagrostietum epigeii and Galio borealis–Artemisietum ponticae occupy the zonal positions. Their communities are characterize by high activity of meadow-steppe mesoxerophytes that are the diagnostic of the class Festuco-Brometea. The meadow mesophytes dominate in subtaiga steppe meadows absolutely; meadow-steppe species are rare. They are marked with a lack of diagnostic species of alliance Galatellion biflorae. They are ascribed to the class Molinio–Arrhenatheretea, order Galietalia veri and alliance Trifolion montani as the communities Filipendula stepposa–Cenolophium denudatum and Astragalus danicus–Potentilla anserinа. Forest steppe meadows of alliance Aconito barbati–Vicion unijugae (order Carici macrou­rae–Crepidetalia sibiricae, class Molinio-Arrhena­theretea) are usual for northern, subtaiga subzone of the Tobol and the Irtysh watershed. Diagnostic species list of the communities belonging to the order Carici macrourae–Crepidetalia sibiricae on West-Siberian plain is impoverished in comparison with the uplands and the mountains of South Siberia wh ere this order was described by Ermakov et al. (1999). We have revealed 2 new associations of alliance Aconito barbati–Vicion unijugae: Aegopodio podagrariae–Brachypodietum pinnati and Dracocephalo ruyschiani–Heracleetum sibiricae. In subtaiga subzone communities of these associations occupy the small well drained habitats between mesophytic forests and arable lands. The first association unites the xerophytic forest meadows with Aegopodium podagraria dominance, occurring only on right bank of the Ishim River. The second one includes forest meadows of subtaiga widely spread on the Tobol and the Irtysh watershed. Association Dracocephalo ruyschiani–Heracleetum sibiricae comprises two subassociations: D. r.–H. s. typicum and D. r.–H. s.molinietosum caeruleae. One of diagnostic species of the last mentioned subassociation is Molinia caerulea that is a common species of boreal wet meadows of Europe. The eastern border of this species distribution is on the left riverside of the Ishim River. Meadows of alliance Festucion pratensis of order Arrhenatheretalia are characteristic only for subtaiga, they belong to two associations. Meadows of subassociation Cirsio setosi–Phleetum pratensis pastinacetosum sylvestris are widespread. They are wide spread over the abandoned arable lands and rather monotonous by their floristic composition. The floristic peculiarity of plant communities is abundance of diagnostic species of classes Artemisietea и Chenopodietea. Meadows of Agrostio tenuis–Festucetum pratensis Yamalov 2005 occur on sandy soils; they present one of the first stages of pine forest demutation. Some of species are not characteristic for typical subassociation described by S. M. Yamalov (2005), therefore the meadows of this association on the Tobol and the Irtysh watershed are referred to a new subassociation A. t.–F. p. senecionetosum jacobaea.

The work submitted in this paper presents the first checklist of the ant species of the Segura River Basin based on a review of specific literature and biological material collected during field work conducted from 2012 to 2017. Our findings recorded 110 species belonging to 30 genera of ants and twenty two of these species were recorded for the first time in this area. The zoogeographical composition is dominated by the species of the Mediterranean zone (75.2%), followed by the mixed and deciduous forest zone (19.1%). The most important zoogeographic elements are: Iberian (20%), Holomediterranean (17.1%) and West-Mediterranean (13.3%). There are only six cosmopolitan species (5.71%). There is a greater proportion of species from the mixed and deciduous forest zone in the high-mid altitudes in the Segura River Basin, where the climate is cooler, and more humid. The Euro-Caucasian and Euro-West Siberian elements seems to be more associated to the more humid forest, whilst the Euro-Caucasian elements seem to be more associated to ecosystems more similar to the forest-steppe zone. The existence of these different zoogeographic origins in this area is probably linked with: the position between Africa and Europe; the complex geotectonic, paleogeographic, and paleoclimatic history during the last 7 My; the complex geomorphology; and the high climate and habitat diversity. Based on ant studies and other taxa, possible explanations of the zoogeographic origin of these ant chorotypes are proposed.

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).

Data on findings of seven species of vascular plants that are new records for the spontaneous flora of the Left Bank Forest-Steppe zone of Ukraine are presented. Four species (Artemisia umbrosa, Sedum album, Ribes aureum, and Prunus tomentosa) are alien plants completely naturalized in the studied area; other three species are treated by author as representatives of the indigenous fraction (Cerastium kioviense, Rhododendron tomentosum, and Vicia lathyroides). Cerastium kioviense and V. lathyroides are considered not rare species in the studied region but rather overlooked by botanists due to their early flowering period. Four species (A. umbrosa, C. kioviense, R. aureum, and P. tomentosa) were for the first time found in Poltava Region, two species (R. aureum, P. tomentosa) – in Kharkiv Region, and one (V. lathyroides) – in Kyiv Region. For all reported species, lists of their localities, places of original descriptions and nomenclatural types are indicated. The species name Prunus tomentosa is lectotypified.

Different Levels

Nowadays, bioecological characteristics of species are the basis for flora and vegetation studying on the different levels. Bioecological characteristics of species is required in process of flora studying on the different levels such as biotopes or phytocenoses, floras of particular areas (floras of ecologically homogeneous habitats), and floras of certain territories. Ramensky scale is the one of first detailed ecological scales on plant species ordination in relation to various environmental factors; it developed in 1938 (Ramensky, 1971). A little later (1941), Pogrebnyak’s scale of forest stands was proposed. Ellenberg’s system developed in 1950 (Ellenberg, 1979) and Tsyganov’s system (Tsyganov, 1975) are best known as the systems of ecological scales on vascular plant species; these systems represent of habitat detection by ecotopic ecomorphs of plant species (phytoindication). Basically, the system proposed by Alexander Lyutsianovich Belgard was the one of first system of plant species that identiified ectomorphs in relation to environmental factors. As early as 1950, Belgard developed the tabulated system of ecomorphs using the Latin ecomorphs abbreviation; he also used the terminology proposed in the late 19th century by Dekandol (1956) and Warming (1903), as well as terminology of other authors. The article analyzes the features of Belgard’s system of ecomorphs on vascular plants. It has certain significance and advantages over other systems of ecomorphs. The use of abbreviated Latin names of ecomorphs in tabular form enables the use shortened form of ones. In the working scheme of Belgard’s system of ecomorphs relation of species to environmental factors are represented in the abbreviated Latin alphabetic version (Belgard, 1950). Combined into table, the ecomorphic analysis of plant species within association (ecological certification of species), biotope or area site (water area) gives an explicit pattern on ecological structure of flora within surveyed community, biotope or landscape, and on environmental conditions. Development and application by Belgrard the cenomorphs as «species’ adaptation to phytocenosis as a whole» were completely new in the development of systems of ecomorphs and, in this connection, different coenomorphs were distinguished. Like any concept, the system of ecomorphs by Belgard has the possibility and necessity to be developed and added. Long-time researches and analysis of literature sources allow to propose a new coenomorph in the context of Belgard’s system of ecomorphs development: silvomargoant (species of forest margin, from the Latin words margo – edge, boundary (Dvoretsky, 1976), margo – margin, ad margins silvarum – along the deciduous forest margins). As an example of ecomorphic characterization of species according to the system of ecomorphs by Belgard (when the abbreviated Latin ecomorph names are used in tabular form and the proposed cenomorph is used), it was given the part of the table on vascular plants ecomorphs in the National Nature Park «Orelsky» (Baranovsky et al). The Belgard’s system of ecomorphs is particularly convenient and can be successfully applied to data processing in the ecological analysis of the flora on wide areas with significant species richness, and the proposed ecomorph will be another necessary element in the Belgard’s system of ecomorphs.
