Dubyna D.V., Ennan A.A., Vakarenko L.P., Dzyuba T.P., Shykhaleeva H.M. (2017). The territorial and ecologo-coenotic differentiation of the vegetation in Kuyalnytskyi estuary valley (Odessa region). Chornomors’k. bot. z., 13 (4): 428–443. doi: 10.14255/2308-9628/17.134/1

 

The natural vegetation of the Kuyalnytskyi estuary valley characterized by the high level of phyto- and coenodiversity and satisfactory condition. Its current territorial differentiation are depends from geomorphological conditions and anthropogenic factors influence. Large areas were drained and covered by halophylic vegetation after catastrophic reduction of the estuary. The pioneer Therosalicornietea halophytic vegetation are occupied lowest periodically flooded areas The saline grassland strips and saline steppe vegetation of Festuco-Puccinellietea were formed in drier conditions around the estuary. The dense stands of Phragmites australis with Tripolium pannonicum were in wedging fresh water places. The dry slops are occupied by steppe Festuco-Brometea communities and shrub Rhamno-Prunetea communities, and alsoby artificial trees and shrubbery Salicetea purpureae plantings. The steppe vegetation were dominated on the left slops, shrub and tree-shrub vegetation were prevailed on the right slops. Tanaceto millefolii-Galatellion villosae communities of the saline steppe were distributed in the southern part of the valley only and occupied large areas on the right estuary bank. Phragmito-Juncetum maritimi (class Juncetea maritimi), Anisantho tectori-Glycyrrhizetum glabrae (Festuco-Puccinellietea), Schoenoplectetum litoralis (Phragmito-Magnocaricetea), Stipa pulcherrima comm. and Stipa tirsa comm. (Festuco-Brometea) were rarest communities in the valley estuary.

Abstract

Umatets О.Yu., Moysiyenko І.І. (2017). Record of Mediterranean species on island Tendra (Black See Biospheric Reserve). Chornomors'k. bot. z., 13 (4): 444–450. doi: 10.14255/2308-9628/17.134/2

 

Three litoral psamophytic species of Mediterranean origin (Cerastium tauricum, Clypeola jonthlaspi, Echinophora sibthropiana) are reported for the first time on the island Tendra (Black See Biosphere Reserve). Information about the distribution of the following plants on the island (Carex liparocarpos, Medicago marina, Glaucium flavum, Alyssum borzaeanum and Elytrigia striatula), which were found earlier, are described. We hypothesize that there is a correlation between the arrival of these plants on the island and abnormally powerful storms. Finally, since all eight species are protected, we discuss the problems of preserving the populations of these plants in the region.

Abstract

Pavlova N.R., Pavlova V.V., Bolsheha O.O. (2017). Аnatomical structure of the one-year stem (Diospyros virginiana L.). Chornomors’k. bot. z., 13 (4): 451–456. doi: 10.14255/2308-9628/17.134/3

 

The peculiarities of the anatomical structure of the one-year stem D. virginiana are analyzed and revealed. It is characterized by a subepidermal peredermum with rounded lentils raised over the covering tissues. They are placed by a continuous ring along the axis of the stem lamellar parenchyma with the domination of scleralenchymal fibers in the perimedular zone. Its characterized by the absence of clearly pronounced triangular regions of the heart rays in the secondary phloem. Well-developed mechanical tissues (lumbar cranial hips, pericyclical sclerenchyma, bast fibers, fibroids, libriform) are present in all areas of the stem. Stocking parenchyma of the primary cortex, phloem, xylem, and the core rays of the peripheral and middle parts of the core are key characteristic of anatomical structure. The distribution of mechanical and parenchymal tissues makes it possible to characterize the anatomical structure as mesoxerophytic.

45 bryophytes species on not recultivated areas of sulfur mining dump, and 32 species on recultivated areas were found. Biomorphological analysis of mosses was provided. Wefts and turfs are dominates mosses biomorfs on not recultivated areas. Turf is widespread biomorfs on recultivated areas. Most species of mosses from not recultivated areas are mesotrophic mesophytes and xeromesophytes which grows on wide substrate specter. However, terricolous mesotrophic xeromesophytes and mesoeutrophical gigromesophytes mosses are present in recultivated areas. According to our research, recultivation can significantly stabilize the micro-climatic and edaphic conditions. The results are suggest an important role of bryophytes as indication of vegetation condition on devastated areas and monitoring of their restoration.

The corticolous lichen communities in the old parks of Kherson region are presented by five new associations and two subassociations. Alyxorio varii-Xanthorietum parietinae has diagnostic species Alyxoria varia, Phaeophyscia nigricans, Scythioria phlogina and forms under influence of the sea winds in arid condition on a neutral bark of old trees (Fraxinus excelsior, F. pensilvanica, Populus alba, Salix alba). Melanelixio subargentiferi-Ramalinetum farinaceae has diagnostic species Melanelixia subargentifera, Phlyctis argena, Ramalina farinacea and colonize of the old trees with neutral bark (Fraxinus excelsior, Quercus robur) in shaded steppe forests and parks. Pioneer hemibasophilous, xerophilous, heliophylous association Rinodino pyrini-Calogayetum lobulatae forms on bark of the different trees in young parks of the southern Ukraine and differs from other nitrophylous communities by Calogaya lobulata, Myriolecis hagenii and Rinodina pyrina diagnostic species. These association are belong to the Xanthorion parietinae Оchsner 1928 alliance. Nitrophilous, heliophilous, xerophilous association Amandineo punctate-Xanthorietum parietinae subass. typicum is widespread in southern Ukraine on different tree species and has diagnostic species Amandinea punctata, Physcia adscendens and Xanthoria parietina. Subassociation Amandineo punctate-Xanthorietum parietinae subass. candelarielletosum efflorescentis has diagnostic species Pleurosticta acetabulum and Candelariella efflorescens and found in the old parks in southern Ukraine. Ombrophilous, scyophilous, mesophilous communities of the association Chaenotheco trichiali-Amandinietum punctatae has diagnostic species Amandinea punctata and Chaenotheca trichialis and forms on old trees at age 100–200 years (Quercus robur, Populus alba, P. nigra). It is member of alliance Buellion canescentis Barkman 1958. Lectotypes of association Buellietum punctiformis typicum Barkman 1958, Parmelietum acetabulae typicum Ochsner 1928, Physcietum adscendentis typicum Ochsner & Frey 1926 are selected.

The data about two new for Ukraine species of the genus Orbilia Fr. – Orbilia comma Graddon and O. flavidorosella Rehm are given. The species O. comma is reported for the first time in Eastern Europe. Both species were identified during studies of apothecial ascomycetous fungi, conducted in the territory of the Kharkiv Forest-Steppe in 2010–2017, as well as during revision of materials from scientific mycological herbarium of V.N. Karazin National University of Kharkiv CWU Myc. The work contains original descriptions, illustrations and data on the distribution of the aforementioned species in Ukraine and worldwide. Taking into account these species, and the record of O. crystallina, reported earlier, a total of 20 species of the Orbilia genus are recorded in Ukraine up to date.

The features of the growth of Crataegus ucrainica (Rosaceae) on the Shelestiv island in the floodplain of the Dnipro river (Kaniv Natural Reserve)

Abstract

Shevchyk O.V., Kupach T.H., Demyanenko S.O., Shevchyk V.L., Solomakha V.A. (2017). The features of the growth of Crataegus ucrainica (Rosaceae) on the Shelestiv island in the floodplain of the Dnipro river (Kaniv Natural Reserve). Chornomors’k. bot. z., 13 (4): 522–532. doi: 10.14255/2308-9628/17.134/8

 

The existing features of Crataegus ucrainica A. Pojark in the floodplain of the Dnipro river (Shelestiv island) are investigated. This habitat includes 14 individuals (20–25 years old) of C. ucrainica. It is located opposite the more mature population (55–60 years old) which was discovered at the mouth area of the Ros’ river earlier by authors. Three soil profiles around 2 meters deep were dug out in the descent places of dried straits. For two profiles located in close proximity to the C. ucrainica individuals, the location of two or three loams and clays stratums of varying thickness at different depths was founded. These stratums provides existence of this species on the alluvial sands array. In the third profile, which was located in the same conditions, but without the presence of C. ucrainica, the shallow waterproof stratums were not detected. Coenotically investigated vegetation groups of these localities are classified as Salicetea purpurea Moor 1958. Coenotic conditions of the habitat of this species in the mouth area of the Ros’ river are similar. Investigated location exists in the absolute reserve regime. This habitat is good model for observing the conservation of the population and organizing long-term monitoring of its development.
