Dubyna D.V., Ennan A.A., Vakarenko L.P., Dzyuba T.P., Kiriushkina H.M., Shykhalyeyeva H.M. (2019). Dynamics of vegetation of the Kuyalnitskyi estuary valley (Odesa region). Part 2. The anthropic successions of vegetation. Chornomors’k. bot. z., 15 (4): 316–333. doi: 10.32999/ksu1990-553X/2019-15-4-1

 

The anthropic changes in vegetation occur under the influence of powerful external factors associated with human activity. In the valley of the Kuyalnitskyi estuary, the anthropic changes exceed natural in terms of its scale and degree of influence. The main factors of such changes are pasture, pyrogenic, phenicial, recreational and a number of man-made. The halophytic and halophytic meadow vegetation of the coastal areas of the lower reaches of the Velykyi Kuyalnik and the estuary are most affected by the pasture. The steppe and shrub vegetation of the slopes of the valley are influenced a pyrogenic factor and forest logging. The influence of the phenicial and recreational factors are manifested on a narrower scale. The action of local anthropic factors are enhanced by the action of global or local natural factors. The complex effect of local grazing and global climatic factors on halophytic-meadow and steppe communities are lead to their unification, loss of the autochthonous elements and formation unproductive associations Aegilopsetum cylindricae Buia et al. 1969, Hordeetum murini Libbert 1932, Anisantho-Artemisietum austriacae Kostylev1985 on the coast. Modern steppe vegetation of the valley slopes was formed under the influence of a pyrogenic factor. It intensifies desertification processes, which occur under the influence of geomorphogenic and climatic factors. Subsequently, frequent fires will result in substitution of desert-steppe zone steppe groups with domination of Agropyron pectinatum, Elytrigia repens, E. intermedia and Ephedra distachia. Forest melioration was carried out by means of terracing the slopes. These violates the processes of historical development of the steppe and significantly changes the environment, which violates the natural development of flora and vegetation. Elaeagnus angustifolia, E. commutata and Cotinus coggygria have a strong expansive activity. The first two species formed a strip of woody vegetation around the estuary, displacing the natural halophyte-meadow groups. The last species forms very dense thickets on many parts of the right-bank slopes. The regeneration of indigenous steppe vegetation occurs quite slowly in areas were tree-shrub plantations perished.

Abstract

Shevchyk V.L., Smoliar N.A., Solomakha N.A., Shevchyk T.V. (2019). Ecological and coenotical characteristics of the Orzhytsia River habitats as a perspective object of Ukraine Emerald Network.Chornomors’k. bot. z., 15 (4): 334–343. doi: 10.32999/ksu1990-553X/2019-15-4-2

 

Physical and geographical characteristics of the Orzhytsia River valley with Hnyla Ornitsa tributary are presented. Variety of habitats included in the list of the Resolution 4 of the Bern Convention enables considering this territory as a promising object of the Ukraine Emerald Network. This is facilitated by availability of a number of objects of the Nature Reserve Fund of Ukraine («Orzhitskyi» and «Timkivskyi» hydrological reserves, «Plysiv Yar» botanical reserve, «Zagat» protected ecosite etc.) in the studied territory. 17 Emerald habitats have been established for the Orzhytisa River valley, their ecological and coenotical characteristics and features of territorial distribution are given. General evaluation of botanical component of the vegetation types has been carried out, as well as location of rare plant species on this territory, included in the Sozological Lists of different ranks (regional (9 species), national (the Red Book of Ukraine – 5) and international (in particular, Bern Convention – 3). It is necessary to preserve and protect the rare species populations of Iris hungarica, Jurinea cyanoides, Ostericum palustre, which, having other sozological statuses, are included in the Annex I of the Resolution 6 of the Bern Convention (1998). Some measures of ecological management of this territory are suggested, in particular it is expedient to prohibit further plowing of the terrain, drainage of floodplain areas, afforestation of meadow-steppe slopes, burning of dry grass and stimulation of grass mowing of grasses and their grazing by running type.

Abstract

Havrylenko N.O.(2019). Amygdalus ledebouriana Schlecht. in conditions of culture in the dendopark "Askania-Nova". Chornomors’k. bot. z., 15 (4): 344–350. doi: 10.32999/ksu1990-553X/2019-15-4-3

 

The success introduction of the Amygdalus ledebouriana Schlecht with international sozological status in the dendrological park "Askania-Nova" was analyzed. It has a high level of adaptation to regional natural and climatic conditions. Plant height is from 1.1 m to 1.3 m. Average size of leaves is 4.3±0.12 sm × 1.1±0.08 sm, perianthes of leaves – 0.96±0.09 cm × 0.56±0.05 sm, stone-fruits – 2.5±0.08 sm × 2.1±0.1 sm, stones – 1.9 0.07 sm × 1.4±0.06 sm. The weight of 100 units medium-sized stones is 89.9 g. Amygdalus ledebouriana belongs to plant with an early onset of vegetation renewal. The dendro-rhythm type is a early-middle and time of the flowering is a early-spring. The duration of the growing season is 213–232 days. The phenological lag is 131–133 days from the beginning of flowering to the full ripening of the fruits. Growth of shoots is 92±11 days. The annual growth of shoots is stable 15.5±0.7 – 16.1±0.7 sm. It blooms abundantly every year and bears fruit in single years. It form viable fruits which have high soil germination in some methods of preplant preparation. The species is characterized by a high vegetative reproductive ability, due to which it increases its living space and is fixed on new places of growth. A. ledebouriana is characterized by significant winter hardiness in the dendropark and drought resistance from medium to high range (usually the tips of the leaves are "burned", sometimes the leaves turn yellow). In some years, the leaves are affected by spot hole disease (Clasterosporium carpophilum), and some shoots by brown rot disease (Monilinia). Damage to other plant organs and other biotic factors were not observed.

The soil cover structure and biomass characteristics of the phytocenoses in ArcelorMittal Kriviy Rih waste dump were studied. Soil cover structure and soil contour parameters were detailed using 3D-modelling. The use of the 3D-modelling is more objectively in contrast of mapping for industrial landscapes characterization. It confirms by increasing of object area by 50%. The waste dump area, according to the map is 38 ha, account for, and it is 55 ha according to 3D-model, the correction factor is 1.44. Confirmed, that 3D-modelling is necessary to predict the industrial objects self-recovery intensification and dynamics. It also useful to assess the quality of fertile and potentially fertile soils applying to waste dump survey. Structure of soil cover at waste dump is represented by combinations of primitive soils which have different genesis and depth with rocky substrates. More developed soils are situated on clay substrates. Phytocenoses with domination of Koeleria cristata, Achilea nobilis and Lathyrus tuberosus are adapted to survive and distribute on waste dumps with clay cover. Plant communities with Securigera varia, Hieracium echioides and Poa angustifolia domination are adapted to the stone substrates. Phytocenoses with Koeleria cristata domination are forming the biggest biomass (103.4 g/m2) on clays. The most biomass formed in Securigera varia phytocenoses – 20,9 g/m2 on the stone substrates. The average biomass of the grass phytocenoses on waste dumps for clay soils are 21.8 g/m2, and for stone substrates are 6.9 g/m2.

Abstract

Sushynska N.I., Korshykov I.I. (2019). The content of photosynthetic pigments in leaves of Berberis thunbergii forms in the Kherson region. Chornomors’k. bot. z., 15 (4): 362–370. doi: 10.32999/ksu1990-553X/2019-15-4-5

 

We carried out comparative studies of the photosynthetic pigments content in leaves of one- and two-year shoots in eight decorative forms of Berberisthunbergii DC. from the Agrobiostation – Botanical Garden collection of the Kherson State University. The chlorophyll content and carotenoids sum were defined in the leaves of these forms in July and early October, when there were no visual signs of leaf aging. The forms are differed by various colours of leaves: green, green with white-gray spots, purple, purple with yellow strip, purple with white-gray spots, yellow. In October, the chlorophyll content and carotenoids was higher than in the leaves of the same forms in July in the vast majority of forms. The maximum levels of the chlorophylls (2.51 mg/g) and carotenoids (0.89 mg/g) were found in green-coloured leaves with white-gray spots in the form “Kelleris” in October. In July, these rates were 2.11 mg/g and 0.64 mg/g respectively. The lowest content of the chlorophylls (0.22 mg/g) and carotenoids (0.11 mg/g) were in July in the leaves of two-year shoots of the yellow-leaf dwarf "Bananza gold". The content of photosynthetic pigments were generally higher in the leaves of one-year shoots vs. two- year ones. Ratio of chlorophyll a/chlorophyll b to chlorophyll sum/ carotenoids sum were varied during the growing season. It is varied from 1.0 to 3.1 and 1.0 to 3.3 in July and from 1.9 to 3.1 and from 1.3 to 4.0 in October. Usually, forms with green leaves had a higher content of the chlorophyll a and band their sums vs. forms with purple and especially yellow leaves. This applies to the carotenoids sum in July also. In October, most carotenoids were found in leaves of the forms with purple leaf color, exception for the form “Kelleris”. The significant differences in the leaf colouring of decorative forms B. thunbergii are a real guarantee for the creation of colourful garden arrangements in parks and squares.

Abstract

Kochergina A.V., Leontyev D.V. (2019) Addition to the species composition of myxomycetes of Shatskyi National Nature Park. Chornomors’k. bot. z., 15 (4): 371–381. doi: 10.32999/ksu1990-553X/2019-15-4-6

 

In August 21–23, 2018, 32 species of myxomycetes from 25 genera, 10 families, 6 orders, and 2 subclasses of the class Myxomycetes were found on the territory of the Shatskyi National Nature Park. Among species revealed this study, only 9 were found during the previous survey of this reservation area in 2004. In the taxonomic spectrum of myxomycetes of the Shatskyi NNP, calculated on the basis of findings of both 2004 and 2018, the subclass Columellomycetidae is represented by 36 species (58.1%), while the Lucisporomycetidae includes 26 species (41.9%). Representatives of orders Stemonitidales (17; 27.4%) and Physarales (16; 25.8%) and families Physaraceae (13 species, 21%), Amaurochaetaceae (10; 16.1%), Trichiaceae (9; 14.5%), Stemonitidaceae and Cribrariaceae (7; 11.3% each) appear to be most common in the National Park. Among genera, the most species-rich are Cribraria Pers., Stemonitis Roth, and Physarum Pers. 17 species of myxomycetes (50.0%) formed fruiting bodies on the dead wood, 15 species (44.1%) were collected on the bark of living trees; species diversity on the leaf litter (7; 20.6%) and the branch litter (6, 17, 7%) was significantly lower. Only one species, Symphytocarpus trechispora (Berk. ex Torrend) Nann.-Bremek., was found on live grassy angiosperms and bryophytes, on the Sphagnum bog. Among the substrate-forming plants, Pinus sylvestris L. (25 species; 73.5%), Alnus glutinosa (L.) Gaertn. (10; 29.4%) and Betula pendula Roth (7; 20.6%) appeared to be the most favorable for the myxomycete fructification under the conditions of the Shatskyi NPP; significantly fewer species were found on substrates formed by Populus cf. alba L. (3; 8.8%), P. tremula L. (2; 5.9%), Quercus robur L. (2; 5.9%), Pyrus communis L. (1, 3%) and Betula pubescens Ehrh. (1, 3%). Interestingly, in the eastern part of Ukraine, Q. robur and P. tremula seem to be much more favorable for myxomycetes. Among the discovered species, 23 are new to the National Park and 18 are new to Western Polissia (forest belt in the North of Ukraine). Licea hydrargyra Nann.-Bremek., T.N. Lakh. & R.K. Chopra, L. pumila G.W. Martin & R.M. Allen and Symphytocarpus trechispora have been recorded in Ukraine for the first time, and the first two species are also new for the Eastern Europe. The discovering of these species became possible due to the moist chamber method, which was never used before in studies of myxomycetes in Western Polissia region.

Fungi of Pseudospiropes M.B. Ellis genus (Helotiales, Leotiomycetes, Ascomycota) in Ukraine

Abstract

Mieshkov Ya.V, Akulov O.YU. (2019). Fungi of Pseudospiropes M.B. Ellis genus (Helotiales, Leotiomycetes, Ascomycota) in Ukraine. Chornomors’k. bot. z., 15 (4): 382–395. doi: 10.32999/ksu1990-553X/2019-15-4-7

 

The article summarized data on Pseudospiropes M.B. Ellis representatives, which have been poorly studied in Ukraine. Basing on the literature review and critical revision of specimens stored in the scientific mycological herbarium CWU (Myc), for Ukraine at least four species of this genus can begiver: P. simplex (Kunze ex Pers.) M.B. Ellis, P. nodosus (Wallr.) M.B. Ellis, P. josserandii (Bertault) Iturr. and P. obclavatus M.B. Ellis. Complete nomenclature characteristics, detailed descriptions, distribution in the world and Ukraine, substrate preferences and periods of sporulation of these species considering also the characteristics of the natural zones, where these fungi were found, are given below. The article contains dichotomic key and original illustrations of asexual morphs for all species. It was shown that the first find of Strossmayeria basitricha (Sacc.) Dennis in Ukraine(teleomorph Pseudospiropes simplex) was recorded by Albert Pilat while his expedition to Zakarpattia (sample PRM 149988). But in the monograph of J.Velenovsky it mentioned as a new for science species Gorgoniceps pilatii Velen. In more modern articles location of the sample is wrongly indicated as Czechoslovakia. Therefore information about this find has not been mentioned in the mycological publications dealt with fungi of Ukraine. The article gives a detailed analysis of taxonomic relevance of morphological criteria that traditionally are used for identification of twine-species P. josserandii andP. simplex. The majority of the Pseudospiropes samples from Ukraine are represented by anamorph, occasionally there are some apothecia at the same time with asexual sporulation. Therefore we are not able to use morphological criteria of sexual structures. It is proved that the thickness of the basal scar as a hallmark is unreliable because it depends on the maturity of spores. Now there is only one feature that allows identifying species P. josserandii andP. simplex in anamorph stage – wideness of the basal scar of the conidia. To assess the reliability of this criterion, it is necessary to carry out molecular phylogenetic analysis.
