In the article the species composition and diversity of lichens of Oleshkivski suburban sandy area are given. This site was founded as a farmstead in the late 1940’s – mid 1990’s and intensely used as garden and vegetable garden for agricultural products and for feeding animals. Since the mid-1990s a transformation of rural estates in suburban plot had begun. It takes place nowadays as well. There is a number of plant species that grow on sand. The territory of the kitchen-garden, the garden and the court is planted with weeds, perennial and annual flowers. Mosses and lichens settled at the planted trees and other substrates. Currently, there are 67 species of wild herbaceous plants, 12 species of aromatic, 77 species of flowers and ornamental plants and 44 species of vegetables. Trees, shrubs and climbing plants are presented by 69 species, bryophytes – by 17 species, lichenicolous mushrooms – by 1, lichens – by 18 species. Some representatives of the flora of Ukraine are indicated in the environmental documents.

The results of the study showed that all industrial sites of metallurgical and coking plants, sludge dumps are characterized by alkaline or strongly alkaline reaction of the substratum, which is almost unchanging on the territory of the ecotope. For this index the most unfavorable conditions were developed on the territory of Enakiev Metallurgical Plant and sludge dumps of Donetsk Metallurgical Plant. The strong alkaline reaction of the substratum in most cases is the limiting factor for the growth of plants. Analysis of the type and degree of salinity showed no salinity of all the studied samples with a predominance in the consist of sulfate ions and calcium ions. The amount of absorbed bases of the substrate studied technogenic ecotopes ranges from 4.35–23.60 mgekv / 100 g of the rock. The lowest values was recorded in the dumps substrates of the Nikitovsky hydrargyrum plant, Enakievo Metallurgical plant and sludge dumps of Donetsk Metallurgical Plant. The highest values of absorbed bases were observed on the territory of Avdeevka coke plant, which is confirmed by the presence on the territory of plant communities.

It is provided information about expansion of Crataegus ucrainica A. Pojark. according to results of study of herbariums, literature and original researches. Ecological and coenotic features of new locations of species and described the current state and expansion its population are shown. The authors note that main natural habitat is located in Forest-Steppe region of Dnipro left bank. Results of research of locations C. ucrainica,including earlier studied coenopopulation on the Dnipro right bank (on outflow of the Ros river) [Shevchyk et al., 2016], is certified ecological originality of this species. Comparative morphological analysis of herbarium materials helps better identify species and clarify its geographic, ecological and coenotic natural habitat. It is emphasized general necessity of protection of new location of C. ucrainica – rare species on the European and global level.

This article reviews quantitative approaches to assessing the quality of phytocoenons and phytocoenotic classification. Mathematical criterion is based on calculating phytocoenon’s compactness / distinctness ratio computed from a distance matrix between releves by species composition. Floristic criterion assumes evaluating diagnostic power of species and takes into account total amount of differential species which are classified statistically with fidelity indexes. We also considered related methods which European phytocoenologists applied for the same purpose – among them indexes of sharpness and uniqueness of syntaxon and the Optimclass approach. We measured resemblance of phytocoenotic classifications of the dataset using contingency tables and nominal correlation coefficients. We determined stability of phytocoenons and the robustness of the cluster topology using bootstrapping methods.

The first data about 183 species of lichens and 17 species of lichenicolous fungi of Nature Reserve “Gorgany” (Ukraine) are given. Abrothallus usneae Rabenh. is a new for Ukraine, and species Homostegia piggotii (Berk. & Broome) P. Karst., Lichenostigma gracile Calat., Nav.-Ros. & Hafellner, Micarea cinerea (Schaer.) Hedl., Sphaerellothecium parmeliae Diederich & Etayo, Stigmidium fuscatae (Arnold) R. Sant., Tephromela grumosa (Pers.) Hafellner & Cl. Roux are new for Ukrainian Carpathians. The locations, ecology and notes to each species are presented.

A comparative study has been carried out on the impact of citrate and sulfate of zinc and manganese on the biomass composition of mycelium of medicinal mushroom Trametes versicolor 353cultivated in a liquid media. It was demonstrated that sulfates and citrates of studied metals have different effects on the mycelial growth and some biochemical parameters. Sulfates and citrates of these metals influence to different degrees on the amount of some amino acids in the mycelium of T. versicolor 353. Also citrates of both metals decrease amount of cis-linoleic acid (C18:2) relative to the control medium and medium with sulfate of appropriate metals.

We present the results of research macrophites algae Western Gulf of Dzharylgach Black Sea. The variety of algae species is represented by three divisions: Chlorophyta, Rhodophyta, Phaeophyta. In the investigated waters dominated by representatives of the division of Rhodophyta, which make up 47 % of the total number of found species of algae. Second place belongs Chlorophyta – 12 species (38 %). Among the representatives of Phaeophyta was discovered 5 species (15 %). When comparing the data with previous studies revealed changes in qualitative structure.

Compiled taxonomic structure of algae Western Gulf of Dzharylgach Black Sea by family who dominated the algal flora in the study, the dominant species and species that have the highest frequency of occurrence.

This article presents information about lichens of five Kryvyi Rig iron ore dumps. 58 species of lichens from 29 genera and 16 families were found. One species – and Trapelia obtegens (Th. Fr.) Hertel is rare for the champaign area of Ukraine. Most species of lichens are represented epiphytic (21) and saxicolous (20) ecological groups. Also noted 8 soil and 9 habitat generalists. Most often on iron ore dumps are species Candelariella aurella (Hoffm.) Zahlbr., Lecanora dispersa(Pers.) Röhl., Massjukiella polycarpa (Hoffm.) S.Y. Kondr., Fedorenko, S. Stenroos, Kärnefelt, Elix, J.S. Hur & A. Thell, Phaeophyscia orbicularis (Neck.) Moberg, Physcia adscendens (Fr.) H. Olivier, Rinodina pyrina (Ach.) Arnold and Xanthoria parietina (L.) Th. Fr.

At the parched areas of the Kuyalnik Estuary, in alkaline soils covered by communities of true saline vegetation and brackish forb meadows, 42 species of Cyanoprokaryota were revealed by cultures. They belong to 19 genera, 10 families and 4 orders from subclasses Synechococcophycidae (41,5 %), Oscillatoriophycidae (34,1 %) and Nostochophycidae (24,4 %). Characteristic features of the studied habitat are the constant presence and quantitative predominance of cyanoprokaryota in the samples comparing to diatoms and chlorophytes, high number of species per sample, a considerable variety of heterocytous taxa and abundant development of representatives of Nostocales in soil cultures. Ecologically, most of the species are aquatic-subaerophytes known as halophytes (11,9 %), halobionts (40,1 %) and halotolerants (47,6 %). Sites with different plant associations differed in species composition and taxonomic structure of Cyanoprokaryota, which may be associated with varying soil moisture. Identified species analyzed in terms of current views on their taxonomy. New records for Ukraine are Pseudocapsa maritimaKomárek, Leptolyngbya norvegica (Gomont) Anagn. et Komбrek, Phormidium litorale Golubić, Ph. viride (Vaucher ex Gomont) Lemmermann, Porphyrosiphon fuscus Gomont ex Frémy, Nodularia crassa (Voronichin) Komárek, Hübel et M. Hübel. The checklist of Cyanoprokaryota of the Kuyalnik estuary based on the original and literature data is given.
