У Львові досліджено 18 об'єктів з озелененими плоскими дахами екстенсивного типу, влаштованими на різних висотах та різних типах будівель. Проаналізовано сучасні методи та технології створення озеленених дахів та висвітлено основні напрями досліджень у цій галузі. Розглянуто основні принципи класифікації і типіфікації зелених дахів. Здійснено інвентаризацію видового складу культивованих і спонтанних видів рослин. Виокремлено групи зелених дахів за домінуючою біоморфою використаних видів: з перевагою сукулентів; газонні дахи; з участю ефіроносних рослин середземноморської флори; з використанням деревних рослин. Вперше у працях такого типу досліджено спонтанну ценофлору, яка супроводжує культурфітоценози зелених дахів. Встановлено, що вид озеленення істотно впливає на формування фітоценозу та визначає основні напрями агротехніки утримання насаджень екстенсивного даху. Виявлено тісну залежність між типом озеленення даху та видовим різноманіттям спонтанних рослин. Встановлено шляхи поширення діаспор занесених видів. Флористичний аналіз спонтанної ценофлори плоских зелених дахів показав, що вона сформована 59 видами, більшість з яких є рудеральними бур'янами із синтаксономічного класу Molinio-Arrhenatheretea. Другу за чисельністю групу складають сегетальні бур'яни із класу Stellarietea Mediae, що свідчить про високу агротехніку утримання рослинних композицій на дахах, де переважають спонтанні види першого етапу заростання оброблених земель. Серед виявлених видів бур'янів переважають стрижнекореневі полікарпічні анемохоричні гемікриптофіти, що характеризує спосіб їх занесення у рослинні композиції. Більшість із досліджених видів не були занесені із субстратом, а поселилися пізніше за допомогою поширення діаспор вітром. Чисельні групи складають види-барохори та антропохори, які заносяться у процесі виконання агротехнічних робіт. Оскільки занесені види рослин здійснюють негативний вплив на художньо-естетичну, декоративну та екологічну функції озеленених дахів, вперше доведено ефективність та доцільність запропонованих досліджень у цьому напрямі. Запропоновано скоригувати агротехнічні прийоми з метою утримання видового складу рослинних композицій, та впровадити ефективні екологічно безпечні заходи для запобігання забур'яненню рослинних композицій зелених дахів.

The museum-preserve «The Kulikovo Field» is situated in the northern part of the Central Russian Upland within the forest-steppe zone near its northern border. There are a lot of abandoned fields, most of them left fallow since 1990–2000 years; the exact age of the old fields is unknown. Using the Braun-Blanquet approach as well as the method of K. Kopecký and S. Hejný (Kopecký, Hejný, 1974; Kopecký, 1992), the classification of the old-field vegetation of the central part of the museum-preserve was carried out. One derivate community, 2 basal communities (one of them with two variants), 3 communities and one association with three variants have been identified. The derivate community Conyza canadensis­ [Artemisietea vulgaris/Stellarietea mediae] is dominated by annual and biennial ruderal species: Conyza canadensis, Lactuca serriola and Carduus acanthoides. The association Convolvulo arvensis–Elytrigietum repentis is heterogeneous both in its floristic and subdominant composition and it can be divided into 3 variants. The variant typica represents monodominant communities where Elytrigia repens prevails. The variant Lactuca serriola is characterized by high constancy of Conyza canadensis, Lactuca serriola and some other ruderal plants and it represents coenoses dominated by Elytrigia repens with subdominants such as Lactuca serriola, Senecio jacobaea and Pilosella spp., mainly P. bauhini. The variant Cichorium intybus is dominated by Elytrigia repens with a subdominant Cichorium intybus; some mesophilous meadow species are often present. Variants Melilotus officinalis and Sonchus arvensis of the basal communityElytrigia repens–Cichorium intybus [Artemisietea vulgaris] are dominated by Cichorium intybus, Poa angustifolia and Elytrigia repens, the first of them also by Melilotus officinalis, Artemisia absinthium, and the second by Carduus acanthoides and Calamagrostis epigeios. Unlike the foregoing syntaxa the basal community Elytrigia repens–Cichorium intybus [Artemisietea vulgaris] is characterized by relative high constancy of some species pertaining to the order Galietalia veri, namely Fragaria viridis, Galium verum, Potentilla argentea. These species and also Poa angustifolia are the first steppificated meadow plants that appear in the old field communities under investigation. The community Pilosella bauhini [Onopordion acanthii] is dominated by Pilosella spp., mainly by P. bauhini that sometimes replaced by some ruderal plants, e. g. Achillea nobilis or Cichorium intybus. The peculiarity of this community is the low constancy and abundance of Elytrigia repens. The species of the orders Galietalia veri and Arrhenatheretalia play much noticeable role in the other syntaxa mentioned below, so these syntaxa are between the natural and synanthropic vegetation. The community Leucanthemum vulgare–Galium mollugo [Onopordion acanthii/Molinio-Arrhenatheretea] is distinguished by high abundance and constancy of some mesophilous and xeromesophilous meadow plants (Leucanthemum vulgare, Galium mollugo, Phleum pratense etc.). The community Artemisia marschalliana [Onopordion acanthii/Galietalia veri] is dominated mostly by Leontodon hispidus and Pilosella spp.; its peculiarity is a relatively high constancy of species common in the local steppificated meadows. The basal community Poa angustifolia [Galietalia veri/Artemisietea vulgaris] represents monodominant communities where Poa angustifolia prevails. Annual, biennial and some perennial ruderal species are rare in this variant, unlike most of the syntaxa mentioned above. The common feature of the last three syntaxa is subdominance of Fragaria viridis. It is known that the floristic composition of communities is changed during an old-field succession: the percentage of annual and biennial species declines and that of species pertaining to the classes of natural vegetation increases (Bonet, Pausas, 2007; Yamalov et al., 2008; Pankratova, Gannibal, 2009). Using the life-form and phytosociological spectrum of the syntaxa analysis an attempt to evaluate succession status of the described communities was made (tab. 9, 10). Based upon the results of this analysis, it is possible to suggest that the derivate community Conyza canadensis [Artemisietea vulgaris/Stellarietea mediae] is the earliest stage one can find in the investigated old fields. The variants Lactuca serriola and typica of the association Convolvulo arvensis–Elytrigietum repentis and the community Pilosella bauhini [Onopordion acanthii] are the next in the series. It seems that Pilosella spp. (P. bauhini and probably some other species of this genus) outcompete the pioneer species of initial stages, like Elytrigia repens, in some cases. The basal community Poa angustifolia [Galietalia veri / Artemisietea vulgaris] seems to be the most advanced stage: the percentage of annuals and biennials is minimal, and that of species pertaining to the syntaxa of natural vegetation of the high ranks, especially to the order Galietalia veri, increases greatly. Species richness of the communities is minimal at the most early stage, which is the peculiarity of the old-field vegetation (Pankratova, Gannibal, 2009; Ovcharova, Yamalov, 2013). Similar phenomenon was also noticed at the succession stages where strong dominant (Elytrigia repens or Poa angustifolia) pre­vails, regardless of how much advanced these stages are, the fact mentioned earlier (Prach, 1985). Species richness attains maximum at those stages of succession where the communities are polydominant and contain both early- and late-successional species, that was also previously described (Meiners et al., 2007).

AbstractThe work deals with vegetation zonation in temporary ponds within cold holes in the Western Taurus mountain chain. There are two main factors that cause differentiation within the studied vegetation: one relates to the microtopography, the other to altitude. In the bottom of temporary ponds, marsh vegetation of Ranunculo argyrei-Tanacetea argentei (Sedo nani-Convolvuletalia galactici) appears (an endemic class vicariant to Scheuchzerio-Caricetea fuscae); in the intermediate zone, the vegetation is dominated by therophytes of Stellarietea mediae (Thero-Brometalia) and in the upper part, there is vegetation of hygrophilous grassland communities of Molinio-Arrhenatheretea (Potentillo-Polygonetalia). This zonation of communities can be found at lower altitudes (up to 1600 m); whereas at higher altitudes, the intermediate zone dominated by therophytes gradually disappears and then also the hygrophilous grasslands. The work also provides a description of new syntaxa, to wit: Ranunculo argyrei-Tanacetea argentei, Sedo nani-Convolvuletalia galactici, Rorippo aureae-Eleocharidion quinqueflorae, Sedo nani-Ranunculetum argyrei, Trifolio caudati-Hordeion geniculati, Taeniathero caput-medusae-Hordeetum geniculati, Alopecuro vaginati-Trifolion resupinati and Ornithogalo lanceolati-Elymetum repentis.

Neste estudo apresenta-se uma classificação fitossociológica com base em inventários próprios realizados, de acordo com a metodologia fitossociológica, em comunidades herbáceas vivazes e anuais, nas subprovíncias Luso-Estremadurense, Carpetana-Leonesa e Orolusitana Atlântica, abrangendo o SE & CE de Portugal continental. O objetivo principal é a descrição das comunidades herbáceas do ponto de vista da composição e variabilidade florística, da ecologia, da distribuição e abundância na área de estudo, da sintaxonomia, dos contactos catenais, da sindinâmica e do estatuto de conservação, tendo como base os dados recolhidos no campo e obtidos através de pesquisa bibliográfica. Foram identificadas 9 classes de vegetação herbácea, 3 classes de vegetação arbustiva, 3 classes de vegetação arbórea e 65 associações no total. Assim, as comunidades inventariadas distribuem-se pelas classes: Isoeto-Nanojuncetea; Magnocarici elatae-Phragmitetea australis; Stellarietea mediae; Tuberarietea guttatae; Poetea bulbosae; Festuco-Brometea; Lygeo-Stipetea; Stipo giganteae-Agrostietea castellanae e Molinio-Arrhenatheretea. Foram identificadas 14 ordens, 20 alianças, 43 associações e 7 subassociações, no conjunto das comunidades terofíticas e vivazes estudadas, desde biótopos oligotróficos, nitrófilos e higrófilos a mesofíticos. Obtiveram-se 12 sintaxa que correspondem a habitats da Diretiva Habitats, alguns dos quais prioritários para conservação. É apresentada uma aproximação a um modelo dinâmico-catenal no qual se identificam os padrões de resposta das comunidades herbáceas a vários fatores de perturbação. Conclui-se que o conhecimento obtido a partir da Geobotânica, nomeadamente da Sinfitossociologia, constitui uma ferramenta essencial para uma gestão sustentável do território.

The paper indicates the phytocenoses most rich in bee taxons and occurring in habitats located along railway lines crossing Lublin Upland. To date, in the study area 124 basic phytocoenoses have been discovered, described and classifi ed into 12 different synecological groups. Among 52 phytocoenoses, the participation of bee flora was considerable. Most voluble phytocoenoses represent ruderal and segetal associations (<i>Artemisietea vulgaris</i>, <i>Stellarietea mediae</i> classes - 87 species), meadow and pasture associations (<i>Mollinio-Arrhenatheretea</i> - 56 species), psammophilous and xerothermic grasslands (<i>Festuco</i>- <i>Brometea</i>, <i>Koelerio glauce</i>-<i>Corynophoretea canescensis</i> - 38 species), thermophilous forest edge communities and thickets (<i>Trifolio</i>-<i>Geranietea</i> and <i>Rhamno</i>-<i>Prunetea</i> - 33 species). Significantly fewer melliferous and polleniferous taxons were noticed in mesophilous deciduous forests or thermophilous oak forests - 29 species. Most simple in structure and species richness are associations with <i>Rumex acetosa</i>, <i>Reseda lutea</i>, <i>Linaria vulgaris</i>, <i>Papaver rhoeas</i>, <i>Cirsium arvense</i>, <i>Oenothera biennis</i>, <i>Viola arvensis</i> and <i>Potentilletum anserine</i> or <i>Sisymbrietum altissimi</i>. The communities form patches (15-20 m<sup>2</sup>) with 80-100% cover of the diagnostic taxon and are of low or medium stability. The most persistent and floristically stable are <i>Tanaceto Artemisietum</i>, <i>Rudbeckio</i>- <i>Solidaginetum</i>, <i>Echio</i>-<i>Melilotetum</i>, <i>Sambucetum nigrae</i>, <i>Rubo fruticosi</i>-<i>Prunetum spinosae</i> and communities with <i>Rosa rugosa</i>, <i>Rubus caesius</i>, <i>Geranium robertianum</i>, <i>Pastinaca sativa</i>, <i>Trifolium medium</i> or <i>Euphorbia cyparissias</i>. The maintenance of the mosaic of phytocoenoses in anthropogenically transformed habitats, including those along railway lines, is of decisive importance for the protection of floristic diversity and adaptation processes of Apoidea.

Results of the studies on the floristic biodiversity of the kurgans in the Pontic desert steppe of the Black Sea Lowland (Kherson Region) are presented. Twenty-six of about 130 kurgans higher than 3 m, distributed over an area of approx. 1500 km<sup>2</sup>, were surveyed and the flora of 5 microhabitats within every kurgan (top, southern and northern slope, southern and northern foot) was examined. The richness of the kurgan flora is estimated at 305 species. Species of alien origin constituted 23% of the total flora, which indicates limited anthropogenic influence. Species of two classes, <em>Festuco-Brometea</em> and <em>Stellarietea mediae</em> were predominant, which also confirmed the semi-natural character of the kurgan flora. The lowest number of species was recorded on top, which was relatively rich in synanthropes, particularly therophytes (<em>Stellarietea mediae</em>). The north side was richer in species than the south side of the kurgans. Steppe species were the most stable and important component of the flora of the slopes (45-47% of the species represented the class <em>Festuco-Brometea</em>). The total flora of the foot contained more species and was more diversified than the flora of the slopes (although the mean number of species was similar in both habitats), but each species occurred at low frequency. There was a higher proportion of species which were introduced from the area surrounding the kurgans, e.g. weeds, halophytes, meadow species, as well as trees which are rarely found in the desert steppe zone. In spite of the small size of the kurgans, significant differences between the floristic composition of the various microhabitats were detected.

Βασικός στόχος της διατριβής είναι η καταγραφή της ιθαγενούς και επιγενούς χλωρίδας της Καλύμνου, καθώς και η φυτοκοινωνιολογική μελέτη και καταγραφή των μονάδων βλάστησης του νησιού.H χλωρίδα της Καλύμνου αποτελείται από 831 taxa, 242 από τα οποία αναφέρονται για πρώτη φορά από το νησί. Το Linum grandiflorum Desf. αναφέρεται ως νέο επιγενές για την Ελλάδα. Πολυπληθέστερη οικογένεια είναι τα Leguminosae. Στο βιοφάσμα της Καλύμνου υπερέχουν τα θερόφυτα, ενώ στο χωρολογικό φάσμα τα Μεσογειακά γεωστοιχεία, από τα οποία σημαντική παρουσία έχουν τα Ανατολικομεσογειακά γεωστοιχεία. Στο χωρολογικό φάσμα της επιγενούς χλωρίδας, η οποία περιλαμβάνει 61 taxa, υπερτερούν τα Αμερικανικά γεωστοιχεία. Έπειτα από σύγκριση της χλωρίδας της Καλύμνου με τη χλωρίδα γειτονικών νησιών, με χρήση του δείκτη ομοιότητας του Sørensen, προκύπτει ότι η Κάλυμνος παρουσιάζει τη μεγαλύτερη χλωριδική συγγένεια με την Κω και τη Ρόδο. Στη χλωρίδα της Καλύμνου περιλαμβάνονται 17 ελληνικά ενδημικά taxa, 5 από τα οποία είναι τοπικά ενδημικά του Ανατολικού Αιγαίου. Από το σύνολο της χλωρίδας, 54 taxa περιλαμβάνονται σε εθνικούς και διεθνείς καταλόγους σπάνιων και απειλούμενων φυτών. Σύμφωνα με παρατηρήσεις μας, τρία taxa αμμόφιλης βλάστησης, με σημαντικότερο το Pancratium maritimum L., απειλούνται με εξαφάνιση από το νησί.Η βλάστηση μελετήθηκε με χρήση της μεθόδου Braun-Blanquet. Συνολικά πραγματοποιήθηκαν 152 φυτοληψίες. Tα αποτελέσματα της φυτοκοινωνιολογική έρευνας δείχνουν ότι η βλάστηση της Καλύμνου εντάσσεται σε 10 κλάσεις (Quercetea ilicis, Cisto-Micromerietea julianae, Crithmo-Staticetea, Saginetea maritimae, Cakiletea maritimae, Asplenietea trichomanis, Nerio-Tamaricetea, Thero-Brachypodietea ramosi, Stellarietea mediae και Isoeto-Nano-Juncetea). Στις 7 πρώτες αναγνωρίστηκαν συνολικά 9 τάξεις, 10 ενώσεις, 7 φυτοκοινωνίες και μία υποφυτοκοινωνία, καθώς επίσης και 16 φυτοκοινότητες, οι οποίες δε φαίνεται να αντιστοιχούν σε γνωστές από τη βιβλιογραφία φυτοκοινωνίες. Κάποιοι από τους τύπους βλάστησης που εντοπίστηκαν στην Κάλυμνο είναι σπάνιοι στο νησί, ενώ αρκετοί εμφανίζονται ιδιαίτερα υποβαθμισμένοι, κυρίως λόγω ανθρωπίνων δραστηριοτήτων.

A wide range of ecological conditions on anthropogenic sites makes it easy for different usable species to infiltrate and spread there. The data were collected since 1998. The spontaneous flora of railway areas of the central-eastern part of Poland is composed of already recorded 950 vascular plants, of which 373 are recognized as usable, including 78 dye plants, 162 medicinal, 324 nectariferous or polleniferous taxons. The majority of taxons are distributed in disperse (128 species - 34%) or occur rarely (96 species - 26%). The common or frequent species constitute 40% of usable flora of the studied area. Medicinal and melliferous plants occur most frequently on slopes of trenches and railway embankments in nearly natural habitats. They mostly grow as single individuals or form loose and rarely dense patches. The analysis of their geographical status confirms the ultimate prevalence of apophytes over anthropophytes. Considering syntaxonomic structure, there are mainly species typical for phytoceonoses from <i>Molinio</i>-<i>Arrhenatheretea</i>, <i>Artemisietea vulgaris</i>, <i>Stellarietea mediae</i>, <i>Festuco</i>-<i>Brometea</i>, <i>Querco</i>-<i>Fagetea</i> classes.

This article, which is the first contribution in a series on the ruderal vegetation of the city of Kyiv, presents results of our studies of Stellarietea mediae plant communities occurring in the city. Their current state and phytocoenotic diversity has been determined. Based on modern methods of statistical data analyses, a classification scheme of Stellarietea mediae vegetation in the study area was developed and the leading factors of territorial and ecological differentiation of phytocoenoses were identified. It has been established that within Kyiv City, this class is represented by 24 associations and 3 basal communities belonging to 8 alliances and 4 orders. Their territorial distribution determines the types and intensity of anthropogenic disturbances, as well as the types of soil and its mechanical structure. Selected syntaxa are characterized and compared with their equivalents from other areas of Ukraine. It has been found that the main differences are at the level of co-occurring species, the composition of which mostly correlates with the types of anthropogenic disturbances and availability of water and mineral nutrients. According to the results of the ordination, it has been found that the distribution patterns of plant communities of Stellarietea mediae occur along the salt regime gradient of the edaphotope, as well as of ombro-, cryo-, and thermal regimes of the climate. Based on the phytoindication analysis, the ecological optimums of the plant communities in relation to the leading ecological factors were determined. The performed research supplements the available information about the presence and distribution of such associations as: Digitarietum ischaemii, Setario viridis-Erigeronetum canadensis, and Ambrosietum artemisiifoliae, in the territory of Ukraine. The proposed syntaxonomic scheme should become a basis of typological developments for strategic planning and practical implementation of activities for optimizing the urban environment and for sustainable development of the Kyiv urban agglomeration.

This paper presents a syntaxonomical revision and statistical determination of diagnostic, constant and dominant species of higher syntaxa of Poland based on releves stored in the Polish Vegetation Database. All the analyses were performed on a data set consisting of 43,686 releves containing 2,853 species of vascular plants, bryophytes, algae and lichenized fungi. The data set was subjected to formalized and hierarchical classification, which revealed 44 classes and 153 alliances. The vegetation of Poland is divided into the classes: <em>Zosteretea marinae</em>, <em>Charetea</em>, <em>Elyno-Seslerietea</em>, <em>Violetea calaminariae</em>, <em>Stellarietea mediae</em>, <em>Cakiletea maritimae</em>, <em>Salicetea herbaceae</em>, <em>Isoëto-Nano-Juncetea</em>, <em>Oxycocco-Sphagnetea</em>, <em>Ammophiletea arenariae</em>, <em>Potametea</em>, <em>Thero-Salicornietea</em>, <em>Carici- Kobresietea</em>, <em>Festuco-Puccinellietea</em>, <em>Erico-Pinetea</em>, <em>Juncetea trifidi</em>, <em>Loiseleurio-Vaccinietea</em>, <em>Lemnetea</em>, <em>Quercetea pubescentis</em>, <em>Littorelletea unifiorae</em>, <em>Koelerio-Corynephoretea</em>, <em>Roso pendulinae-Pinetea mugo</em>, <em>Cymbalario-Parietari- etea</em>, <em>Bidentetea tripartitae</em>, <em>Alnetea glutinosae</em>, <em>Scheuchzerio-Caricetea</em>, <em>Robinietea</em>, <em>Montio-Cardaminetea</em>, <em>Thlaspi- etea rotundifolii</em>, <em>Festuco-Brometea</em>, <em>Salicetea purpureae</em>, <em>Molinio-Arrhenatheretea</em>, <em>Mulgedio-Aconitetea</em>, <em>Carpino- Fagetea</em>, <em>Calluno-Ulicetea</em>, <em>Quercetea robori-petraeae</em>, <em>Vaccinio-Piceetea</em>, <em>Polygono arenastri-Poëtea</em>, <em>Asplenietea trichomanis</em>, <em>Phragmito-Magno-Caricetea</em>, <em>Artemisietea vulgaris</em>, <em>Epilobietea angustifolii</em>, <em>Galio-Urticetea</em>, <em>Rhamno- Prunetea</em>. In order to determine a diagnostic species for allianc sures of fidelity were used. A revised list of vegetation units of Poland is presented.
