Based on the analysis of more than 17,000 vegetation plots (relevés), the participation of 261 protected species (254 vascular plants, six lichens, and one bryophyte) in 30 EUNIS grassland habitat types was revealed. Vegetation plots were assigned to the habitat types using the EUNIS-ESy expert system with further verification. We consider as protected species those listed in the current edition of the Red Data Book of Ukraine, Resolution 6 of the Bern Convention, Annexes II and IV of the Habitat Directive, and the IUCN Red List (only categories VU, EN, CR). The participation of protected species was studied according to the following three criteria: (1) the total number of protected species in the plots assigned to a certain habitat type, (2) the number of plots in which at least one protected species is present, and (3) the mean number of protected species per plots within each habitat type. True steppes (R1B) and meadow steppes (R1A) differed with a significant predominance of the total number of protected species. Arctic alpine calcareous grassland (R44) and Continental dry rocky steppic grassland and dwarf scrub on chalk outcrops (R15) had the largest proportion of plots with protected species and the highest mean numbers of protected species per relevé. Saline habitats, in particular Temperate inland salt marsh (R63) and Semi desert salt pan (R64), were characterized by the smallest number of plots with protected species. Among all species, Gymnadenia conopsea, Stipa capillata, Colchicum autumnale and Gladiolus imbricatus occurred in the largest number of studied habitat types. Based on the results of the analysis, appropriate ways of optimizing the protection of grassland habitats and protected species are proposed.

The previously compiled list of species of powdery mildew fungi of Ukraine was published more than 30 years ago. That list included 108 species belonging to 12 genera. However, over the past three decades, numerous changes have been made in the system of the former order Erysiphales, in particular, in its generic composition; moreover, dozens of new species have been described. At the same time, many species of powdery mildew fungi were introduced to Europe, including Ukraine, in particular, from East Asia and North America. Thus, the species composition of powdery mildew fungi of Ukraine has undergone significant changes and requires a critical revision. Therefore, a series of relevant articles is planned to be published. This article, the first in the series, deals with the small genera Arthrocladiella and Blumeria. A list of species of these genera recorded in Ukraine (Arthrocladiella mougeotii, Blumeria avenae, B. bulbigera, B. dactylidis, B. graminicola, B. graminis, and B. hordei), their distribution by regions of Ukraine and a key for identification are provided. Arthrocladiella mougeotii was found to occur occasionally only in nine regions, mainly in the southern part of Ukraine, primarily in the forest-steppe and steppe zones and on the South Coast of Crimea. Blumeria avenae was recorded only in two regions, on the South Coast of Crimea and in Central Polissya and should be also considered rare in Ukraine. The remaining species were observed quite often and registered in 14–24 regions, while B. graminicola and B. graminis are regarded as the most common ones.

The article provides results of the quantitative score assessment of environmental conditions of plant communities (biotopes) and comparative analysis of the topological (altitude) gradient of changes using the method of synphytoindication and the Mountain Crimean geobotanical zone as an example. Of the 126 biotopes listed for the Mountain Crimea, we selected for the analysis 68 forest, shrub, grassland and petrophytic types, reflecting the patterns of topological differentiation, i.e. β-coenotic diversity within five geobotanical regions and altitudinal zones of the southern and northern macroslopes. In the article, we highlight the specifics of the methodology of field research and data processing, based on geobotanical relevés entered into the database in the TURBOVEG software and selected ecological and coenotic profiles. At the next stage, we assessed the living conditions of the biotopes by applying modern methods and programs TWISPAN, STATISTICA-7. On the basis of key biotopes, we identified combinations within the altitude zones treated as mesocombinations and those within the macroslopes – as macrocombinations. In the article, distribution of biotopes by mesocombinations, macrocombinations and geobotanical regions is provided. The model ecological-coenotic profiles of each geobotanical region of shrub-forest and petrophytic-grass series were built showing distribution of biotopes and graphs of the indicators of major ecological factors. The regularities of altitude changes and the nature of correlation were established. For climatic factors (thermo-, cryoregime, humidity, and climate continentality), we calculated relevant indicators and coefficients used in climatology. The obtained data form the basis for assessing the differentiation of biotopes, comparative analysis of the ecological conditions and forecasting potential changes.

The effect of pre-sowing priming with gibberellic acid (GA3) solution (50 mg/L) on acorn germination and growth characteristics of 47-day-old plants of Quercus robur and Q. rubra was studied under laboratory conditions. The priming effect varied depending on the oak species and development phase of the plants. After priming, 86% of Q. robur acorns germinated that exceeded the control by 25%, while the number of sprouted acorns of Q. rubra was at the control level and amounted to 85%. The 47-day-old plants of Q. robur were divided into three groups: (1) sprouted acorns with cracked pericarp and main root; (2) seedlings with formed epicotyl and apical bud; (3) seedlings with unopened true leaves of juvenile type. The plants of Q. rubra were divided into two groups: (1) seedlings with formed epicotyl and apical bud; (2) seedlings with open true leaves. In plants of Q. robur, priming caused decrease of biomass in cotyledons, while no visible changes were found for those of Q. rubra. An increase in growth characteristics, fresh and dry biomass accumulation was noted for all Q. robur plants whereas thickening of shoots was observed only in seedlings of the second group. Instead, hormone treatment of acorns of Q. rubra led to inhibition of growth processes in plants of both groups. In general, priming with GA3 solution enhanced germination of acorns and stimulated growth of Q. robur plants and, conversely, slowed the growth of Q. rubra plants. Exogenous GA3 did not eliminate the syndrome of unfriendly seedlings of the studied oak species, but improved the viability of acorns and increased the number of seedlings/shoots.

The article presents the results of mycological research conducted during 2013–2021 in Hutsulshchyna National Nature Park. The main tasks were to study the species diversity of ascomycetes and to identify new localities of rare species. As a result, 35 new records are reported for the park. Among them, Discina ancilis, Morchella elata, M. semilibera, Otidea cochleata, Pyrenopeziza benesuada, Rutstroemia conformata, Sarcosphaera coronaria, and Verpa bohemica were recorded in the Carpathian forests for the first time. Anthracobia maurilabra, Choiromyces meandriformis, Dumontinia tuberosa, Geopyxis carbonaria, Gyromitra gigas, G. infula, Helvella acetabulum, H. macropus, Hymenoscyphus fagineus, Leotia lubrica, Peziza succosa, P. vesiculosa, P. violacea, Sarcosphaera coronaria, and Spathularia flavida were found each in one or two localities. These fungi do not produce fruit bodies annually and are considered as rarely occurring species in the park. Most of the reported species are confined to deciduous forests.

In 1994 Tzvelev described ×Asterigeron ucrainicus Tzvelev, which he interpreted as a hybrid of Aster amellus L. and Erigeron acris L., and thus established a nothogenus ×Asterigeron Tzvelev (Aster L. × Erigeron L.). However, the name ×Asterigeron Tzvelev is a later homonym of Asterigeron Rydb.; because of that a new replacement name, ×Asterron Olshanskyi, is proposed for this nothogenus. Also, the new nomenclatural combination ×Asterron ucrainicus (Tzvelev) Olshanskyi (≡ ×Asterigeron ucrainicus Tzvelev) is validated.

Syntaxonomy of restoration vegetation in quarry sites in Central Polissya of Ukraine, including 25 classes, 36 orders, 62 alliances, 116 associations, and two unranked communities, is presented. Based on the frequency of occurrence of vegetation plots, we have identified typical and atypical environments in existing and abandoned quarries. The classes Molinio-Arrhenatheretea, Artemisietea vulgaris, Phragmiti-Magnocaricetea, Plantagenetea majoris, and Epilobietea angustifolii were found to be the most common. Predominance of the grassland stage in vegetation restoration under significant or moderate anthropogenic impact is demonstrated. The environmental factors and features of seed dispersal affect the mode and tempo of vegetation restoration in disturbed habitats of open pit mining. Meadow vegetation is predominant on the plateau around the zone of active production; herbaceous and woody plants penetrate the slopes simultaneously. Steep vertical outcrops of crystalline rocks for a long time remain uninhabited by higher vascular plants. Plants grow exclusively in the crevices of crystal blocks filled with loose rocks, soil, and small organic residues. On the slopes of loose sedimentary rocks, the meadow stage is not gradually transformed into the phanerophyte stage. The rate of vegetation restoration depends on the slope angle. Such successions form large ecotone areas due to numerous unfilled ecological niches in the quarry ecosystems. These areas are most vulnerable to the penetration of invasive plant species.

In this review, the concept of fruit morphogenesis is treated in the context of implementation of the evo-devo approach in carpology. A new viewpoint on the fruit morphogenesis is proposed and justified, comprising the pre-anthetic, as well as post-anthetic periods of fruit development, id est, development of the gynoecium, and development of the fruit itself. It is proposed to recognize ontogenetical (individual) and evolutionary (historical) aspects of fruit morphogenesis, the first of them we can study directly, while the second aspect can be only hypothesized or treated as a theoretical model of fruit evolution in consequence of some presumed changes in the individual fruit morphogenesis. In this article these aspects are named as "ontomorphogenesis" and "phylomorphogenesis" of the fruit, correspondingly. Our concept of ontomorphogenesis of the fruit involves four components that could not be brought together, such as changes in the morphological structure of the gynoecium, abscission of the extragynecial floral parts and the style, histogenesis of the fruit wall and other fruit parts, and terminal stages of the fruit morphogenesis (dehiscence, splitting, or abscission). The current state of studies of these components in the individual and evolutionary contexts is discussed. By examining the patterns of fruit evolution, we should consider factors acting at both the post-anthetic and pre-anthetic periods of fruit ontomorphogenesis.

Our concept of ontomorphogenesis of the fruit involves four components that could not be brought together, such as changes in the morphological structure of the gynoecium, abscission of the extragynecial floral parts and the style, histogenesis of the fruit wall and other fruit parts, and terminal stages of the fruit morphogenesis (dehiscence, splitting, or abscission). The current state of studies of these components in the individual and evolutionary contexts is discussed. By examining the patterns of fruit evolution, we should consider factors acting at both the post-anthetic and pre-anthetic periods of fruit ontomorphogenesis.","PeriodicalId":52835,"journal":{"name":"Ukrainian Botanical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46139318","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}

As part of ongoing studies of the lichenized mycobiota of the Aotearoa / New Zealand archipelago we provide formal documentation of the occurrence of Alyxoria ochrocheila, Anisomeridium anisolobum, Fissurina dumastii, Porina americana and Zwackhia viridis. Through their formal documentation in peer-reviewed literature these species can now be accepted as new additions to the lichenized mycobiota of that region.
