In this study, 56 adventive species have been identified in Khakas flora to date. In terms of the introduction method, xenophytes dominate; this group is composed of 44 species, which is 78.6% of all the adventive species under study. The ergasiophyte group consists of 12 species (21.4%). According to the naturalization degree, we identified three groups: epecophytes, agriophytes, and ephemerophytes. The epecophyte group is in the lead and consists of 21 species (37.5%). The agriophytes are represented by 19 invasive species (33.9%). The ephemerophyte group is composed of 16 species (28.6%). Thus, the ratios of the synanthropic-plant groups defined according to the introduction method and naturalization degree indicate that most of these adventive plants have been introduced unintentionally and successfully established themselves on a territory new to them. The adventive fraction of natural ecosystems in Khakas flora contains 20 species included in the report “The Black Book of the Flora of Siberia” [1].

The information about the modern state synanthropization of forest and schrub floristic complexes of the Middle Cis-Dnipro Region (Ukraine) is generalized. The studies complexes recently have been significantly affected by anthropogenic influences and its consequences have led to a change in their floristic composition. The synanthropic fraction of the flora of studies floristic complexes is represent by 262 species of vascular plants, incl. 100 apophytes and 162 aliens. The results of fractional and structural analysis is presented. In the apophytic fraction, the largest number of species belongs to the families Asteraceae (23 species) and Caryophyllaceae (15); in this group are prevail: in the life forms spectra (according to K. Raunkier) – hemicryptophytes (52 sp.); in the hydromorphes spectra – xeromesophytes (36) and meso-xerophytes (32); according to the degree of adaptation of species to transformed ecotops – evapophytes (41) and hemiapophytes (38); by coenotic peculiarity – meadow (35). In the alien fraction, the largest number of species belong to the families Asteraceae (25) and Rosaceae (15); in this group are dominated by: species of North American (44) and Mediterranean (37) origin; according to the degree of naturalization – epoecophytes (64); in the life forms spectra – therophytes (54); in the hydromorphes spectra – mesophytes (75) and xeromesophytes (67). Annotation list of synanthropic fraction species, as well as apophytic and alien, is presented. A separate list of species of the forest and schrub complexes (46), which are able to extend to the transformed ecotopes outside the forest coenoses is presented. The predominance of adventization process over apophytization indicates a significant disruption of the structure of many plant communities. In the alien fraction a high percentage of species tree is observated. The most species as well as of apophytic and alien fractions of the studies complexes in the Region are characterized by high degree of naturalization and active and mass distribution. Some alien species, e.g. Amorpha fruticose, Acer negundo, and Impatiens parviflora etc. in the Region are transformer species, e.g., A. fruticosa is a characteristic species of F1.11 and G 1.112 biotopes; A. negundo dominates in coenosis of G1.35 biotope and formed of plant community in І4.111 and І4.12 biotopes, Impatiens parviflora – in G3.11 and G3.12 biotopes.

AbstractThe results of an investigation of the invasive species in the flora of the Starobilsk grass-meadow steppe are presented. Check-list of alien plant has over 386 species of vascular plants of which 28 species are invasive. We have identified 6 transformer species from the invasive plants. We aggregate data on the entry, distribution history, ecology, occurrence in different plant communities, degree of their naturalization and the habitats where they occur. The leading families of invasive species are: Asteraceae. The basis for this group is presented by origin from the North America and the Mediterranean. With respect to the time of immigration, most of them are kenophytes. By the method of introduction, ksenophytes are dominated; according to the degree of naturalization epoecophytes and agriophytes dominate in this group. With regard to the characteristics of life forms, half of invasive species are terophytes. The vast majority of plants are heliophytes and xeromesophytes. Most species are found in biotopes group I: Cultivated agricultural biotopes; least of all species found in biotopes group F: Biotopes dominated by chamephytes and nanophanerophytes. Only 3 species found in biotopes group F: Biotopes dominated by chamephytesand nanophanerophytes. The maps of distribution of 28 invasive species are provided. Most of the species marked dispersed in more than 30 squares.

Adventive Flora

Biological pollution of natural phytocenoses by adventive plant species poses is a serious threat to endemic species and species with narrower ecological amplitude in ecosystems around the world. This study presents the results of a study of the composition and distribution of adventive plant species in natural, semi-natural and anthropogenic transformed phytocenoses of Volyn’ Polissya, Ukraine. To clarify the effect of drainage melioration on non-native flora species distribution, a botanical study was carried out during the 2003–2019 vegetation seasons on the territory of four drainage systems. The adventive flora of this unique region of Europe was studied in detail for the first time. In total, 279 non-native plant species were found. They belong to 110 genera and 32 families. The results of studying the systematic, bioecological, range-distributional and phytogenetic structure of adventive species found within agricultural lands and adjacent territories are presented. It was found that 161 species are associated with agricultural production. Of these, 90 species were found directly within the agricultural land, another 71 species were found growing in the adjacent territories. It was found that a significant increase in the number of adventive species on the territory of Volyn’ Polissya is associated with drainage melioration carried out in the 1960–1990s, significant changes in the structure and forms of agro-industrial production, and climatic changes in recent decades. The expansion of agricultural land in this area over the past 50–60 years has led to an increase in the number of adventive species by more than 60%. On the territory of drainage systems used for agricultural activities, more than 40% of the total species composition of the adventive flora of Volyn’ Polissya is represented. The majority of these species originate from arid and sub arid regions of the planet. The transformer plants, Solidago canadensis L. and Phalacroloma annuum (L.) Dumort pose a potential threat to phytocenoses of the described region, as well as the whole of Europe. Of particular interest are the species that in the future may pose a serious threat to natural phyto-diversity and have negative practical consequences for the structure of agricultural landscapes. These are Ambrosia artemisiifolia L. and Heracleum sosnowskyi Manden. In general, modern agro ecosystems are characterized by instability and low ability to resist non-native species. The strongly weedy character of cultivated fields and the presence of abandoned uncultivated lands have caused the rapid spread of adventive vegetation. In order to further optimize the structure of agrolandscapes, it is advisable to monitor and regulate not only expansionary invasive species, which is especially important for preventing biological pollution, but also species whose status has not yet been determined.

Рresented the results of floroecological, hydrobotanical and geobotanical researches of the Regional Landscape Park "Samara Plavni". Regional Landscape Park (RLP) "Samara Plavni" is located in the waters of the Samara Bay, which was formed as a result of flooding of the floodplain of the Samara River during the creation of the Zaporozhye (Dnieper) Reservoir and the surrounding area. Conducted a systematic and bioecological analysis of the flora of vascular plants. Studied the composition of the rare fraction of flora and associated flora element. The research was carried out according to the generally accepted methods of floristic, geobotanical and hydrobotanical research. Bioecomorphic characteristics of species (selection of ecomorphs) are compiled according by A. L. Belgard ecomorph system using the following ecomorphs: biomorphs (one-, two-, perennials); heliomorphs (relation to light); hygromorphs (relation to the aquatic environment); tropomorphs (relation to nutrition); cenomorphs (growth in certain phytocenoses). Ecological characteristics of species were given from literature sources and according to the results of many years of own research. The analysis of the adventitious fraction was carried out at the time of drift – archaeophytes, neophytes. Advent status was determined on the basis of literature data. Vegetation of the regional landscape park "Samara Plavni" is represented by natural and semi-natural groups. The main area of shallow water is occupied by massifs of Phragmites australis (Cav.) Trin. ex Steud and groups of submerged vegetation. The tree and shrub vegetation of the park is represented by natural forest complexes, semi-natural groups and artificial plantations. Meadow and meadow-swamp vegetation of the landscape park is represented by complexes of associations of mesophytes and hygrophytes. The floristic list of vascular plant flora is 617 species. Hemicryptophytes, perennials, sciogeliophytes and heliophytes, mesotrophs, mesophytes, hygrophytes predominate here. Among cenomorphs, most species are represented by meadow (139) and forest (108) species. The rare fraction of flora is 73 species. There are 128 species of ruderal flora and 140 species of adventive flora, including 6 invasive species. At the time of entry into the study area allochthonous element of flora is divided into two groups: archaeophytes – 63 species (45%) and neophytes – 77 species (55%).
