Title: Natural phytomelioration processes on rock dumps of abandoned coal mines (Ukraine) Authors: Попович, Василь Васильович; Волощишин, Андрій Ігорович; Лисий, Назар; Петльований, Михайло Володимирович; Шуплат, Тарас Ігорович Abstract: Mining is accompanied by direct irreversible changes in the biosphere. Analysing the results of recent studies on the anthropogenic hazard of coal mine tailings and the peculiarities of tailings reclamation and phytoremediation on a global scale, it necessitates the investigation of the ecological state and natural phytoremediation of the Nadiya mine tailings in the Lviv-Volyn coal basin. The stages of succession processes on the rock dump surface have been determined. The phytomeliorative efficiency coefficient has been calculated for all periods of the phytomeliorative process on the rock dump surface. The total area of the studied site is 280 m2. Based on the calculations of changes in the dynamics of the phytomeliorative efficiency coefficients at different stages of the phytomeliorative process (KFM=0.155-4.485), it is expedient to conduct reclamation and phytomeliorative operations on the rock dump surface. The coal mining industry causes a significant technogenic burden on the environment, affects human health and transforms living conditions re-gardless of the place or country of extraction. Waste heaps are the most dangerous factors of environmental degradation. Studies of the impact of coal mine waste heaps on the human body and biota are conducted in almost all industrialised countries as well as countries where mineral mines are operated.

Title: The Influence of Climatic and Edaphic Conditions on the Development of Thuja occidentalis ‘Smaragd’ Under the Urban Conditions of a Large City Authors: Kycheryavyi, Volodymyr P.; Popovych, Vasyl; Kycheryavyi, Volodymyr S.; Oleksandra, Dyda; Shuplat, Taras; Bosak, Pavlo Abstract: The negative effects of the urban environment on the morphological and physiological states of Thuja occidentalis ‘Smaragd’ have been investigated. For comparison, two plots were selected for the cultivation of eastern arborvitae cultivars: one in a public garden (the control plot) and the other one in street planting with its positive vertical temperature gradient associated with overheating and dehydration of the soil. This situation had a negative impact on the biometric and physiological parameters of the plants, and, in the end, the level of their vitality. If, under optimal growth conditions, the vertical temperature gradient is negative (the air temperature in the crown is higher and the soil temperature in the rhizosphere zone is lower), the physiological processes in Thuja ocidentalis ‘Smaragd’ (transpiration, water-holding capacity) proceed in a normal mode. A change in the temperature regime (soil temperature is higher than the air temperature in the crown), under the conditions of a positive temperature gradient, leads to negative consequences: the morphological structure of plants changes (the growth of the apical and side shoots slows down, the number of needles increases, the lower parts of the trunks become bared, the length and volume of the crown are reduced), also physiological processes are disturbed – moisture deficiency increases, water holding capacity decreases, the pigment composition of needles changes towards decreasing the amount of chlorophylls (a + b) and carotenoids. A decrease in the vitality level of the study plants with a positive temperature gradient was confirmed by the vitality indices Rfd established by means of the fluorescence method (negative gradient 0.64; positive gradient 0.33).

Title: PREDICTION OF CHANGES IN THE VEGETATION COVER OF UKRAINE DUE TO CLIMATE WARMING Authors: Skrobala, V. M.; Popovych, V. V.; Bosak, P.V.; Shuplat, T. I. Abstract: Purpose. To study ecological regularities of the formation of vegetation cover in Ukraine depending on the climatic conditions and analyze its possible changes due to global warming. Methodology. The research methodology involves the following: diff erentiation of the climatic conditions and evaluation of the signifi cance of climatic indices at the level of territorial units of a geobotanical zoning based on variance analysis; multiple ordering of the geographic locations in terms of climatic indices basing on the analysis of main components (Principle Component Analysis); development of a typological scheme of the vegetation cover relying upon a discriminant analysis; statistic processing of the climatic parameters. Findings. Modelling of spatial diff erentiation of climatic indices depending on the location latitude and longitude as well as altitude above the sea level helped analyze the connection of vegetation cover and climate. It has been determined that peculiarities of the vegetation cover formation according to a scheme of geobotanical zoning is characterized in the most accurate way by the diff erence of such climatic indices as: air temperature in January, July, and August; monthly precipitation amounts during June September; duration of a frost-free period; and hydrothermal coeffi cient of T.G. Selianinov. The main regularity of the formation of Ukrainian vegetation cover has been defi ned. The regularity means the following structure of interrelation between the climatic indices: along with the growing average monthly temperatures of June-September and decreasing precipitation amounts from April to September, the indices of climatic water availability decrease along with the increasing heat availability indices (duration of an active vegetation period and total of temperatures per that period, average annual temperature). This regularity represents a gradient of climatic indices from the Ukrainian Carpathians towards the southern Crimean coast. It has been determined that during some years of the early 21st century, the conditions peculiar for a steppe area were formed for the forest and forest steppe areas. Originality. The vegetation cover of Ukraine is characterized by the ecological range, which is evaluated basing on ordering of the geographical locations in terms of coverage of complex climatic environmental gradients. A typological scheme of the Ukrainian vegetation cover can be represented in a two-dimensional space in the form of square parabola, whose left branch shows a gradient of climatic factors and changes in vegetation cover from the west to the north-east and right branch indicates it from the north-east to the south. Graphic visualization of climatic information on the basis of ecograms and typological schemes of vegetation cover can be used to predict the vegetation cover dynamics due to certain climatic changes. Practical value. While understanding the climatic conditions of geographic locations during certain periods of time, one can identify their location in the ecological and coenotic range of Ukrainian vegetation and predict their stability and possible changes in the vegetation cover due to global warming.

Title: Monitoring of Heavy Metals Migration intoEdaphic Horizons of Coal Mine Dumps Authors: Popovych, Vasyl; Voloshchyshyn, Andriy; Tyndyk, Oleh; Menshykova, Olga; Shuplat, Taras; Bosak, Pavlo Abstract: Abstract. Mining of minerals is accompanied by direct irreversible changes in the biosphere. An analysis of the latest researches on the technogenic hazard of rock dumps at coal mines, as well as specifics of their reclamation and phytomelioration in a global context, necessiates the study of the ecological state and natural phytomelioration of the Nadiya mine waste heap in the Lviv-Volyn coal basin (Ukraine). This scientific work presents the results of research on heavy metals migration into the genetic horizons of the rock dump, as well as their influence on forming the phytomeliorative cover on its surface. It has been revealed that the studied site of the No.4 rock dump in the 0-15 cm horizon, which is located from the eastern side near the foot, is the most contaminated with heavy metals. The indicators of heavy metal content at the background site, which is located within a radius of 3 km from the rock dump, are the lowest in the 0-15 cm horizon. The uneven distribution of heavy metals in the genetic horizons of the rock dump substrate is caused by frequent landslides, changing rock acidity, heterogeneity of natural overgrowth, and existing combustion sources. In the event of precipitation, toxic compounds, heavy metals and other harmful substances are washed out from the rock dump surface, and in our case, these substances also enter the natural water body
