Adventive component flora of the southern part of Sakhalin Island

The article is devoted to the adventive flora of the southern part of Sakhalin Island. Nowadays, 274 species of adventive plants, belonging to 192 genera and 57 families, have been identified here. Five families (Amaranthaceae, Cannabaceae, Commelinaceae, Linaceae, and Malvaceae) are represented by invasive species only. The structure of the leading families and genera is analyzed, the participation of adventive species information of plant communities is indicated. Adventive species are classified into life forms, method of entering and degree of naturalization.

Alien species of the Apiaceae family in the flora of Khabarovsk Territory (the Russian Far East)

The results of studying alien species of the Apiaceae family in the flora of the Khabarovsk Territory are presented. According to our data, 13 alien species of this family, including the invasive species Pastinaca sylvestris are now widespread in the territory of the region. They differ in the degree of naturalization, phytocenotic confinement, and the intensity of settlement.

Is the Naturalization of the Townscape a Condition of De-Industrialization? An Example of Bytom in Southern Poland

A characteristic element of the transformations of cities in Central and Eastern Europe after 1990 was the emergence of shrinking cities. The main problem related to shrinking cities is around how this process developed as a result of rapidly intensifying de-industrialization. While many studies in this area are devoted to demographic, social, and economic issues, relatively few studies address the spatial dimension. In this article, the example of spatial development in the (post-) mining city of Bytom in southern Poland is discussed, pointing to the need for a multifaceted approach to this issue. This article begins with an attempt to contextualize this issue within a broader time perspective. Such an analysis makes it possible to better situate contemporary changes in the context of the processes that were visible in previous periods. Next, these changes are described using two methods. The basis of the first method is comparisons between the different types of land use. The second method, which is emphasized, is the method of A. Macias, which indicates the degree of naturalization/anthropogenization of space. Macias’ method is crucial in the context of discussions about the future of post-mining towns, where attention is paid, among other things, to the issue of sustainable development.

Three new alien Chenopodiaceae species in the flora of Russia

Three new alien species of Chenopodiaceae s. str. (Amaranthaceae s. l.) are reported for the flora of Russia, the North American Chenopodiastrumsimplex and Australian Dysphania carinata and D. pumilio. The identification of the specimens of Chenopodiastrum simplex from Moschny Island in the Leningrad Region (European Russia) was confirmed using both morphological and phylogenetic analyses. Morphologically, C. simplex is very similar to C. badachschanicum having the same fruit and seed characters. A single specimen of Dysphania carinata from Primorye Territory (the Russian Far East) was previously identified as Chenopodium pumilio (≡ Dysphania pumilio) incorrectly. Only recently, the latter species has been indeed found in Beslan town, Republic of North Ossetia – Alania (the North Caucasus). For each species, the possible degree of naturalization is discussed.

Ionoxalis tetraphylla (Oxalidaceae), a new ephemerophyte in the Ukrainian flora

Data about floristic records of Ionoxalis tetraphylla (Cav.) J. Rose (Oxalis tetraphylla Cav.) (Oxalidaceae), a new alien species of Ukrainian flora were presented. Species has Central American origin, its primary area are covers Mexico, Panama, Guatemala, Costa Rica, Caribbean islands. Secondary area spreads on Europe, Asia and Australia. It was found in neighboring countries with Ukraine, including Russia and Belorussia. As a naturalized species it was tagged in some countries of Southern Europe. The main centers of species introduction in Ukraine are M.M. Hryshko National Botanical Garden of NAS of Ukraine, Acad. O.V. Fomin Botanical Garden of Taras Shevchenko Kyiv National University, Botanical Garden of Oles’ Honchar Dnipro National University, Botanical Garden of V.N. Karazin Kharkiv National University, Botanical Garden of V.I. Vernadsky Taurian National University, Syretskyi dendrological park (Kyiv), private gardens and greenery managements in Kyiv and Kyiv Region, Odesa, Kamyanets-Podilskyi (Khmelnytskyi Region) and other regions of the country. Information about spontaneously distribution of the plants in Ukraine nowdays is absent. At the first time some escaped plants of the I. tetraphylla were recorded in 2019 near village Dovzhyk of Zhymomyr District of Zhytomyr Region. Some individuals grew in old pine forest margins near path. Plants successfully overwintered at 2019/2020 years. Taxonomical and morphological characteristics, chorological data (primary and secondary areas) and ecological peculiarities are presented. According to the time of immigration this species is kenophyte, according to the way of introduction – ergasiophyte and according to the degree of naturalization in Ukraine it is ephemerophyte. The species is mesotroph, mesophyte, scio-heliophyte. In conditions of Ukraine it blooms profusely but almost never forms seeds, and reproduces vegetatively – by daughter bulbs. The map of the species distribution (spontaneously and in culture) in Ukraine is presented. Keywords: alien species, Ionoxalis tetraphylla, floristic record, Ukraine

The urban flora of the Yanaul city (Republic of Bashkortostan)

The work is based on the data of field studies carried out by the route method during 2017–2018 within the ad-ministrative boundaries of Yanaul city (Republic of Bashkortostan). According to research results, the flora of Yanaul includes 485 species of vascular plants from 286 genera and 81 families; 174 species are adventive, of which 38 can be classified as invasive and potentially invasive species. Among the most aggressive invasive species are Acer negundo, Echinocystis lobata, Elodea canadensis, Heracleum sosnowskyi, Hordeum jubatum, Lupinus polyphyllus, Xanthium album. Also, large areas within the city are occupied by an invasive species Soli-dago gigantea. 1 relict species (Campanula trachelium) was recorded, growing in the preserved areas with natu-ral vegetation. For each species, the attachment to certain habitats and the frequency of occurrence are given. For adventive species, information on the time, way of invasion and degree of naturalization are indicated. For inva-sive species, their status is indicated.

Synanthropization of forest and shrub florocomplexes of the Middle Cis-Dnipro Region (Ukraine)

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.

Alien species in the vegetation cover of the Park- Monument Of Landscape Art of Local Importance «Park «Zhovtnevyі» Chernivtsi City

This study presents results of ecological-coenotic and biotopic analysis of alien species in the park monument of landscape art of local importance «Zhovtnevyi» (Сhernivtsi city). The forty-six alien species that formed quite dense and numerical populations, belonging to 9 associations, 8 alliances, 8 orders, 7 vegetation classes were identified in the park. Coenoses of the park with the participation of alien plants are mezofitni, hemihidrokontrastofilni, subatsydofilni, semievtrofni, akarbonatofilni, nitrofilni, hemiaerofobni. The main alien plants biotopes in the park are synanthropic, forest (anthropogenic deciduous forests), and ruderalized littoral and herbaceous biotopes. Among the alien plants, according to the time of introduction, kenophytes are predominate, according to the origin, North American, Mediterranean and Mediterranean-Iranian-Turanian species are prevail. According to the degree of naturalization – epecophytes. 16 Species of the park belongs to the group of highly active invasive plant species of Ukraine; 10 species dominate in plant communities of synanthropic biotopes. 5 species are rooted in semi-natural, sometimes natural plant communities, occupy a specific niche, or are constantly renewed in them; 6 species form new plant communities; 5 species are transformers. The activity of alien plants spreading in the park biotopes was analyzed and established that the broadest biotopic amplitude belongs to the Phalacroloma annuum, which is distributed in the seven park's biotopes; 2 species are distributed in five biotopes; 4 – in four and three biotopes; 11 species – in two biotopes; 24 species in one biotope. It has been established that the park's alien plants can easily and quickly spread and inhabit large areas of park cultural phytocenoses, are able to form numerous, dense populations, new plant communities and transform the park's semi-natural biotopes.
