The article describes vegetation diversity patterns of the steppe part of the Synyukha River valley (the Southern Bug catchment area, southern Ukraine), which is represented by 20 alliances, 14 orders, and 13 classes. It has been found that general differentiation of the vegetation is most influenced by edaphic factors (soil moisture, nitrogen content, and aeration), and somewhat less – by damping variability, salinity and acidity regime. The vegetation ecofactors of the alliances Festucion valesiacae, Berberidion vulgaris, Prunion spinosae, and Prunion fruticosae best correspond to the background ecological indicators of the steppe part of the Syniukha River basin. The high cenotic diversity and specific vegetation of the granite outcrops were observed. Based on the calculations, we demonstrated that the steppe part of the Syniukha River catchment area is the southern limit of distribution of Carpinion betuli forests due to the conditions close to the limits of their ecological optimum.

The system of the family Poaceae is dynamically changing due to the progress of phylogenetic research. Consequently, nomenclature of some taxa should be adjusted accordingly. In the Plants of the World Online (POWO) and some other authoritative online sources, some genera and nothogenera are accepted in rather wide circumscriptions; for example, ×Agroelymus E.G. Camus ex A. Camus (including ×Agrotrigia Tzvelev and ×Elymopyrum Cugnac), ×Elyleymus B.R. Baum (with synonyms ×Leymotrigia Tzvelev and ×Leymotrix Kharkev. & Prob.), and Elymus L. (including Elytrigia Desv. and ×Elymotrigia Hyl.). However, Pseudoroegneria (Nevski) Á. Löve and Kengyilia C. Yen & J.L. Yang are now commonly recognized as separate genera. If we accept these taxonomic concepts, several nomenclatural combinations are needed. Thus, some of them are proposed here. I propose a new nothogenus ×Kengdoroegneria Olshanskyi for intergeneric hybrids between species of Kengyilia C. Yen & J.L. Yang and Pseudoroegneria (Nevski) Á. Löve. Also, nine nomenclatural combinations in ×Agroelymus, ×Elyleymus, Elymus, and ×Kengdoroegneria are validated.

New records of Tulipa suaveolens (incl. T. schrenkii: Liliaceae) in Odesa Region are reported. During 2017–2021, 23 localities of T. suaveolens with an area from 1.5 m2 to 730 m2 were found along 5.4 km of the right-bank slopes of the Kuyalnyk Estuary. The total area of all localities was 3458 m2 with a maximum plant density of 78 individuals per 1 m2. Almost all plants had yellow flowers; in some localities, there were plants with other perianth colors, but their number did not exceed 20 %. Based on the original and published data, it is demonstrated that the modern western border of the species range is located along the slopes of the Kuyalnyk Estuary. It has been established that the most negative impact on the steppe vegetation and plants of this tulip species is caused by insufficient precipitation. In particularly dry years (2019, 2020), most plants remained dormant. The habitats of T. suaveolens in the studied area are subject to significant anthropogenic influence and require specific protection measures.

This article investigates the species of the family Sargassaceae present in Kuwait, analyzing nuclear ribosomal internal transcribed spacer 2 (ITS2) sequences of 67 individuals collected in 2018–2020. Morphological characterization and DNA barcoding confirmed the presence of eight taxa that belong to Sargassaceae. Five species belong to the genus Sargassum, while three other taxa, namely Sirophysalis trinodis, Hormophysa cuneiformis, and Polycladia myrica, belong to other genera. For the latter species, there was no ITS2 sequence available so far. As for Sargassum species, previous records based on phenotypic identifications were only confirmed for a minority of species. Based on 100% sequence identity with records from other regions, we recognize S. aquifolium, S. ilicifolium var. acaraeocarpum, S. yinggehaiense, and one still unclear species (Sargassum sp.). According to the sequences, the fifth and most common Sargassum species in Kuwait, previously identified as S. asperifolium, is S. carpophyllum. However, the ITS2 sequence of this entity did not show a perfect match with any S. carpophyllum specimen so far sequenced. The comparatively limited diversity of Sargassum in Kuwait may be due to the prevailing extreme environmental conditions, in particular large temperature amplitude between +14 °C in winter and +37 °C in summer.

This is the second article in a series of critical revisions of the species composition of powdery mildew fungi (Erysiphaceae, Helotiales, Ascomycota) of Ukraine and their distribution within the country. The first article of the series dealt with the small genera Arthrocladiella and Blumeria, while here we consider species of the Erysiphe sect. Erysiphe. Representatives of the other two sections of this genus, Microsphaera and Uncinula, will be critically examined in further publications. In the present article, a list of 24 species of the section Erysiphe recorded in Ukraine, their distribution by regions of Ukraine, and a key for their identification are provided. The most common species frequently occurring in many regions of Ukraine are E. aquilegiae, E. convolvuli, E. cruciferarum, E. heraclei, E. pisi, and E. polygoni. Such species as E. buhrii, E. howeana, E. knautiae, E. limonii, E. lycopsidis, and E. urticae were recorded less often. Erysiphe betae, E. circaeae, E. lythri, E. macleayae, E. mayori, E. thesii, and E. ulmariae are relatively rare species that occurred infrequently in several regions. Erysiphe caricae, E. catalpae, E. caulicola, E. celosiae, and E. malvae are known each from one or a few localities only. A number of species are invasive fungi, most of them have been recorded in Ukraine relatively recently, within the last hundred years. These are E. betae, E. caricae, E. catalpae, E. celosiae, E. howeana, and E. macleayae.

Based on the methods of transverse transects and phytoindication, results of the analysis of ecological and cenotic status of the Dokuchaev shelterbelts and their extremities are provided. A combination of various ecological conditions characterizing formation of vegetation cover in the protective shelterbelts is demonstrated. The current state of plant communities of the forest strips is described. A regionally rare plant species in Kirovohrad Region, Convallaria majalis, is reported. It was established that the investigated shelterbelts were formed under forest-meadow and forest-steppe conditions. The analysis of coenotic features of all studied shelterbelts has proved that they have similar species composition and communities structure. The Dokuchaev windbreaks and shelterbelts need further monitoring of changes in their plantation structure, distribution and introduction of new plant species, as well as ecological and sanitary conditions.

An investigation of the flora, mycobiota and lichenized mycobiota associated with the endemic Aotearoa / New Zealand plant genus Lophomyrtus (Myrtaceae) revealed a specimen of Lepra erythrella (Pertusariaceae). Lepra erythrella, though briefly mentioned in a paper documenting the results of that Lophomyrtus study, has not yet been formally admitted into the lichenized mycobiota of Aotearoa / New Zealand. Therefore, to complete that process in this paper, we provide a description based on the collection made from Lophomyrtus and a further one located in the Allan Herbarium (CHR). The addition of Lepra erythrella to the lichenized biota of Aotearoa / New Zealand highlights not only the lack of collecting of this genus in that archipelago but the need to critically examine that nation’s herbarium collections. We recommend that further research on this genus is carried out in our region.

Three new for Ukraine species, Anema tumidulum, A. nodulosum, and Pyrenocarpon thelostomum (Lichinales, Lichinaceae), are reported. They were found in the Dnister Canyon, on the S and W exposed cliff surfaces where water tracks formed 'a black zone' of the Collematetea cristati class. Other species forming these communities are Anema decipiens, Psorotichia schaereri, Peccania coralloides, Thallinocarpon nigritellum, Thyrea confusa, and Verrucaria nigrescens s. l. The analyzed dataset included three relevés from the Dnister cliff, as well as 14 relevés from literature sources: seven relevés of Peccanio coralloidis-Thyreetum pulvinatae recorded from Poland, and seven relevés of Thyrea nigritella-Anema moedlingense comm. from the Czech Republic. These data were analyzed in JUICE software. All analyzed relevés were separated in two clusters. Three relevés from Dnister Canyon fell into the same cluster with Thyrea nigritella – Anema moelingensis comm. provided by Wirth in 1972. We consider these communities as a new association Thallinocarpo nigritelli-Anemum tumidulae. Diagnostic species of the association are Thallinocarpon nigritellum, Anema tumidulum, Staurothele frustulenta, and Anema nodulosum. The lectotype of Peccanio coralloidis-Thyreetum pulvinatae has been proposed, with diagnostic species Enchylium polycarpon, Leproplaca cirrochroa, Placidium rufescens, Placynthium nigrum, Toninia candida, and Synalissa symphorea. These associations belong to the Peccanion coralloidis alliance and differ by their ecological preferences. The association Peccanio coralloidis-Thyreetum pulvinatae represents the nomenclatural type of the alliance and includes communities on the vertical exposed limestone surfaces in water tracks. The Thallinocarpo nigritelli-Anemum tumidulae association occupies similar habitats but in the xeric geollitoral zone along river banks. The alliance Peccanion coralloidis and order Collematetalia cristati are reported from Ukraine for the first time.

The advantages and disadvantages of some most common methods of quantitative analysis used in processing of synphytoindication data were analyzed. These methods enabled reflection of important ecological characteristics of plant communities and assessment of the nature of their topological and regional differentiation characterizing α-, β-, γ-diversity. We also examined current debatable issues regarding the use of scales of ecological indicator values and methods of their correct comparison based on bringing to a single "denominator". The visual aspects of the gradient analysis used in assessment of topological differentiation of habitats based on the establishment of various types (vector, combinative and complex) of ecological and coenotic profiles are considered. We focused our attention on the application of optimal models of ordination methods (detrended correspondence analysis – DCA, non-metric multidimensional scaling – NMDS). The use of cluster analysis reflected in various methods of dendrogram constructing was evaluated. The analysis of the above methods allows us to evaluate the efficiency of their use in various aspects of synphytoindication techniques. This allows us to use such data for forecasting and modeling biocoenoses changes and development, for assessment and classification of biotopes, landscape structure (ecomer), zoning (ecochor), as well as for evaluation of the resistance of vegetation to the influence of external factors. The methods and approaches of mathematics and cybernetics are expected to be more widely used in geobotany in the future, since many pressing ecological issues related to non-linear development, emergent changes in the ecosystems properties and search for critical thresholds cannot be solved in a traditional way.

We also examined current debatable issues regarding the use of scales of ecological indicator values and methods of their correct comparison based on bringing to a single \"denominator\". The visual aspects of the gradient analysis used in assessment of topological differentiation of habitats based on the establishment of various types (vector, combinative and complex) of ecological and coenotic profiles are considered. We focused our attention on the application of optimal models of ordination methods (detrended correspondence analysis – DCA, non-metric multidimensional scaling – NMDS). The use of cluster analysis reflected in various methods of dendrogram constructing was evaluated. The analysis of the above methods allows us to evaluate the efficiency of their use in various aspects of synphytoindication techniques. This allows us to use such data for forecasting and modeling biocoenoses changes and development, for assessment and classification of biotopes, landscape structure (ecomer), zoning (ecochor), as well as for evaluation of the resistance of vegetation to the influence of external factors. The methods and approaches of mathematics and cybernetics are expected to be more widely used in geobotany in the future, since many pressing ecological issues related to non-linear development, emergent changes in the ecosystems properties and search for critical thresholds cannot be solved in a traditional way.","PeriodicalId":52835,"journal":{"name":"Ukrainian Botanical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43576984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Geographical distribution and habitats of Scutellaria altissima (Lamiaceae), a regionally rare species of the Ukrainian flora, were studied. Its localities within the plain areas in the Forest-Steppe, Steppe (mainly on the Donetsk Ridge) Zones and in the Central Polissya are a part of the large European population of this species. In the Crimean Mountains, a separate exclave of its range within the country is located. In Ukraine, habitats of S. altissima are associated with deciduous forests, mainly with broadleaved forests. In the Forest-Steppe and Steppe Zones, S. altissima is a component of forest communities Scutellario altissimae-Quercion roboris confined to sub-floodplain river terraces and to ravines, respectively. In the Ukrainian Polissya, habitats of S. altissima represent the ecotones between deciduous forests and petrophytic communities. A contiguity of the habitats of S. altissima to river valleys and ravines determines linear (striped) structure of their populations. The impact of anthropogenic pressure leads to transformation of the linear populations into locally isolated ones.
