The article summarizes current data about the condition and spread of Sphagnum mosses on the territory of Male Polissya in Lviv Region based on the material from our own field research, materials of National Herbarium of Ukraine (KW), the Herbarium National Museum of Natural History of the National Academy of Sciences of Ukraine (LWS) and literature data. An annotated list of the species of the genus Sphagnum was compiled and it includes 15 species together with an indication of place and date of collection, the names of collectors, the spread in Ukraine and biotopes in which the species may occur according to The National Habitat Catalogue of Ukraine and EUNIS. Sphagnum fallax (Klinggr.) Klinggr., S. fimbriatum Wils. and S. palustre L. were determined as the most widespread species of the genus Sphagnum in the research area. Two species S. angustifolium and S. inundatum are indicated for the first time for the territory of Lviv region. Six regionally rare species were found: S. capillifolium, S. cuspidаtum, S. fаllax, S. fimbriаtum, S. obtusum and S. papillosum. The possible disappearance of a species Sphagnum centrale, S. contortum, S. flexuosum and S. obtusum on the territory of the Volytsky Botanical Reserve of national importance was established owing to the draining of wetlands. Ecological groups of sphagnum species on the research area were analyzed, where the predominance of subheliophytes (7 species, 46.7 %), hygrophytes (13 species, 86.7 %), cold tolerant species (13 or 87.7 %) and acidophiles (8 species, 53.3 %) was identified. The topicality of the study is determined by the fact that sphagnum mosses are spread much less frequently than other species from the division of bryophytes because they are confined to a narrow range of biotopes. With the drastic changes in the hydrological regime of the environment, which occurred during the second half of the twentieth century, due to the large areas of drained land, the processes of biotope dehydration became irreversible and some species of sphagnum could have disappeared from the territory of Male Polissya. Due to the sensitivity of bryophytes, in particular species of the sphagnum genus, and due to a disturbance of the hydrological regime of wetlands, the waterlogged mixed coniferous forest in the vicinity of the village Kulychkiv is a promising territory for the creation of a new environmentally protected site or the extension of the Volytsky Botanical Reserve of national importance for the purpose of wetlands preservation here.

“…Due to their high tolerance to the effect of ecological change, bryophytes play an important role in succession processes on devastated territories where other plants cannot initially grow (Lobachevska et al, 2005;Glime, 2006;Maestre et al, 2015). By inhabiting such disturbed territories, pioneer moss turfs form a new succession with changes in humidity (Shcherbachenko et al, 2015;Rabyk et al, 2017), mineral (Vilmundardóttir et al, 2018) and organic status of the substrate (Karpinets et al, 2016;Kyyak & Baik, 2016;Karpinets et al, 2017). The participation of bryophytes in the revitalization of plant cover of technogenic ecosystems is determined by their high tolerance to drying (Kyyak & Khorkavtsiv, 2015;Kyyak et al, 2017;, their ability to restore soil due to the structuring of its upper horizons (Carter & Arocena, 2000;Aronson & Alexander, 2013;Jackson, 2015), to prevent its erosion (Haig, 2016;Baughman et al, 2017;Stark, 2017), to absorb and retain moisture (Seitz et al, 2017;Batista et al, 2018;Delgado-Baquerizo et al, 2018), thereby reducing surface runoff (Greenwood & Stark, 2014;Zhao et al, 2014;García et al, 2016).…”

Ecological and physiological peculiarities of bryophytes on a post-technogenic salinized territory

2019

Taxonomic, biomorphological and ecological structures of bryophytes, their reproductive strategy and the main mechanisms of tolerance in the conditions of salinization were investigated. Bryophytes are the pioneers that have colonized the territory of a tailing storage that holds liquid waste from potassium-magnesium concentrate production of the Mining and Chemical Enterprise "Polymineral". Due to excess salts, the soil solution in the shore area of the tailing pond acquires high osmotic pressure. Three experimental plots which differed significantly in the level of the substrate salinity were laid at the distance of 3, 6 and 9 m from the reservoir for experimental studies. Water extracts of the substrates from the test sites showed the highest concentrations for sulfates – 10.4–64.6 mg Eq/100 g of soil and chlorides – 7.6–43.3 mg Eq/100 g of soil. It was established that the investigated areas of the tailing storage territory differed in the biochemical activity of the substrate, which was evaluated by its redox potential. On the areas of the uncovered substrate it was the lowest – 230 mV, which indicates anaerobiosis in conditions of very high salinization and moisture. Higher ROP values were determined at the sites of bryophyte cover distribution – 295–330 mV. The aim of the study was to determine the features of taxonomic, biomorphological and ecological structures of bryophytes, their reproductive strategy and to establish the main mechanisms of adaptation to the conditions of salinization on the tailing storage territory. 24 species and 3 varieties of bryophytes, belonging to 12 families and 16 genera were found on the shore of the tailing storage pond. The results of biomorphological and ecological analysis of bryophytes indicate the uneven conditions of the habitats and their considerable ecological plasticity. Among the bryophytes, mesophytes, xeromesophytes and meso-eutrophs, eutrophs with a life-form of low dense and loose turf dominated. In salinization conditions, dioicous acrocarpous mosses prevailed, the fertile turf of which, depending on the influence of abiotic factors, differed significantly in the number of sexual shoots, their ratio and productivity. Bulbils were found only on the tips of Bryum argenteum shoots. Along with Salicornia europaea L., a euhalophyte, the leading role in the initial stage of overgrowth of the tailing storage area most often belonged to Didymodon rigidulus, Bryum argenteum, Funaria hygrometrica and Barbula unguiculata. The process of formation of bryophyte cover occurred along a gradient of decrease in salt concentration at the experimental sites. Adaptation of bryophytes to substrate salinity is due to a change in metabolic processes, which is manifested in an increase of the total content of carbohydrates and an increase of the cation exchange capacity of moss cell walls, which is the primary barrier that reduces the toxic effect of ions under salt stress.

In the article, the bryophytes of the upper reaches of the Western Bug River, which is physically and geographically located within Male Polissya, partly Roztochia, and to a minor extent in the Gologoro-Voronyatsky denudo-structural hills, have been studied. Based on our survey, a list of the bryophytes has been compiled for the first time. Ecological features, substrate preferences and life forms of the bryophytes have been analysed. According to the ecological features, subheliophytes (30.9%) and hemisciophytes (30.9%) predominate in the spectrum of heliomorphs; mesophytes (29.7%), hygromesophytes (21.2%) and xeromesophytes – in the spectrum of hydromorphs (19.4%); cold-tolerant species (59.4%) – in the spectrum of thermomorphs. Based on the analysis of the substrate preferences of the bryophytes, the following groups were identified: epigeans (116 species), epixils (56 species), epiphytes (46 species), epiliths (43 species), aquatic (22 species). The prevailing life forms are turf (30.3%), rough mat (18.2%), weft (15.2%), tuft (10.3%) and smooth mat (9.7%). 3 species that are officially recognised as rare and 16 species that are recognized as regionally rare have been found. In the group of bryophytes associated with wetland ecosystems, 2 officially rare and 6 regionally rare species were found in the study area. Given the large areas of drained land in Lviv Region, these species are of particular value, especially in the context of conservation of the biodiversity and protection of the valuable natural areas in accordance with the Development Strategy of Lviv Region by 2027.
