We have studied the specific features of the composition of algal groups in forest litters of natural and manmade forest biogeocenoses in the steppe zone. The strongest resemblance is seen between algal groups formed in forest litters with identical compositions of plant debris (leaf or needle). The dominants and the structure of algal groups vary with respect to the season and subhorizon of forest litter, which points to the specificity of the latter as algal habitat. It is characterized by high variability of the thickness and physicochemical properties as a result of biotic and abiotic destruction of plant remains. The needle litter is predominated by Chlorophyta and Xanthophyta (with respect to the species number and abundance) upon the considerable participation of Cyanoprokaryota. When the needle litter is enriched with leaf debris, the species diversity of Cyanoprokaryota increases. The biological diversity of algae in the forest litter is high, and they may play a significant role in the formation of algal communities in soil horizons. © 2017, Pleiades Publishing, Ltd.

The problem of correlating and comparing the levels of the European and national qualifications framework and the potential of the Semantic Web technologies for solving this problem were explored. We substantiated the need for creating models and methods, aimed at providing transparency of the European and national qualifications frameworks and the development of tools for implementing these methods. Authors proposed a reference model of the qualifications framework that formalizes knowledge of basic information objects relating to learning outcomes and their representation in the qualifications frameworks. The specific feature of this model implies using atomic competencies: semantics of information objects of different classes is formalized through the set of such atomic competences that are associated with different properties of these objects. This should provide for the automatic matching of these information objects on the level of knowledge. The methods of quantitative estimation of semantic proximity between information objects of different classes of ontological models, which corresponds to different problems, are proposed in the work. This allows identifying a similarity between learning outcomes, which are described with the use of descriptors of different qualification frameworks. Information regarding atomic competences is obtained from the national and European standards, qualifications frameworks, speciality descriptions, etc. They may be automatically supplemented via analysis of relevant information of Web-resources that contain semantic markup. The work considers in detail the mechanism of integration of the reference information model of competences with technological environment Semantic MediaWiki: ontological concepts and relations are used for semantic markup of Wiki-pages by categories and semantic properties. This allows running a variety of semantic queries to the content of pages, relating to learning outcomes. Examples of such queries are given and their expressive power is analyzed. An example of using the ontological model of competences for improving semantic Web-search for the information for the purpose of supplementing and updating Wiki-pages was studied. The ontology potential in specification of information needs and the increased intersection of the obtained results is demonstrated with the example of the semantic search engine MAIPS. © J.

Molochnyi Liman is the largest liman (22,000ha) at the northern coast of the Sea of Azov. Contrary to estuaries, it is an ecotone without typical tides. It is a half-closed water body, with a connection to the Sea of Azov that has periodically renewed or ceased over the course of time. Molochnyi Liman is a wetland of international importance, a hydrological reserve of state significance and is part of the Pryazovskyi National Natural Park. The results of our research have established that termination of the liman/sea connection has led to significant hydrological changes. The most crucial is a reduction in the liman's depth, accompanied with shrinkage in the water surface area, a dramatic increase in salinity to 95g/l and the loss of several Ramsar criteria. Restoration of the Molochnyi Liman ecosystem requires a positive water balance. There is a need for ensuring the inflow of at least 100mlnm3 of marine water into the liman through a connecting channel. This will renew normal functioning of the liman and reduce the salinity to an optimal level. The methodical approach used in this work can also be applied to other closed and half-closed water bodies of the Azov-Black Sea Region. The development of a hydrological model can be effectively used as a supportive tool for the management of the Tylihulskyi, Khadzhibeiskyi and Kuyalnytskyi limans in the north-western part of the Black Sea. © 2014 Elsevier Ltd.

The Black Sea Catchment is internationally known as one of ecologically unsustainable development and inadequate resource management, which has led to severe environmental, social and economic problems. EnviroGRIDS @ Black Sea Catchment aims at building the capacities of regional stakeholders to use new international standards to gather, store, distribute, analyze, visualize and disseminate crucial information on past, present and future states of the environment, in order to assess its sustainability and vulnerability. The EnviroGRIDS @ Black Sea Catchment project addresses these issues by bringing several emerging information technologies that are revolutionizing the way we are able to observe our planet. The Group on Earth Observation Systems of Systems (GEOSS) is building a data-driven view of our planet that feeds into models and scenarios. EnviroGRIDS aims at building the capacity of scientist to assemble such a system in the Black Sea Catchment, the capacity of decision-makers to use it, and the capacity of the general public to understand the important environmental, social and economic issues at stake. To achieve its objectives, EnviroGRIDS will build an ultra-modern Grid enabled Spatial Data Infrastructure (GSDI) that will become one component in the Global Earth Observation System of Systems (GEOSS), compatible with the new EU directive on Infrastructure for Spatial Information in the European Union (INSPIRE). EnviroGRIDS will particularly target the needs of the Black Sea Commission (BSC) and the International Commission for the Protection of the Danube River (ICPDR) in order to help bridging the gap between science and policy.

Abstract—The article presents results of ecological, chemical, and bioindication assessment of the urban ecosystem of an industrial city in the South of Ukraine. The dynamics of physical and chemical parameters of soil, surface water, and air in various functional areas of the city was analyzed. The complex pollution index for environmental components was determined. Bioindicative assessment of the ecological condition of the urban ecosystem was performed based on vitality parameters of epiphytic lichen flora, soil mesofauna, and freshwater mollusk fauna. Based on bioindicators’ vitality, zones with different ecological conditions were demarcated. Toxic effects of various pollutants on living organisms and tolerance of some bioindicator species under anthropogenic pressure were analyzed. It was found that the amount of zoophages increases and homogenization of anamorphoscope composition of major mesopedobionts groups with the dominance of individual species is observed in anthropogenically transformed areas. In alkaline soils of functional areas of the urban ecosystem, prevalence of calcicole species—millipedes, pill bugs, and gastropods—was noted, which allows them to be used as soils’ alkalization level indicators. The degree of correlation between the viability of bioindicator groups and complex pollution index of basic components of the urban environment was determined. For instance, an inverse correlation between the vitality of epiphytic lichen flora (G, %) and the complex atmospheric air environmental contamination index (Pa) (–0.80, p < 0.05); and a direct correlation between the decline in the vitality of soil mesofauna (G¯ , %) and complex soil contamination index (Zs) (0.84, p < 0.05) were discovered. Therefore, biomorphs of epiphytic lichen flora and some groups of mesopedobionts can be used as pollution indicators for urban environments. Based on the study results, an algorithm for complex ecological, chemical, and bioindication assessment of ecological condition of an urban ecosystem in an industrial city was proposed. © 2016, Allerton Press, Inc.

The article presents materials about algae structure of various polygons on the Arabat Spit. There were 30 species of algae found, represented by four phyla: Cyanoprokaryota (66.7% of the total number of identified species), Bacillariophyta (13.3%), Chlorophyta (16.7%), Xanthophyta (3.3%). Distinct features of their biotopical occurrence and relation to salinity and pHvalue are shown. It was investigated that a list of species shows hydrophilic-amphibial features and algae grow in the conditions of variable salinity and water regimes. There were found 9 algal communities in different habitats of the researched polygons. Dominants of algal communities were cyanoprocaryotic and green algae. Cyanoprokaryota Lyngbya aestuarii (Mert.) Liebm. formed macroscopic growth in all biotopes excepting the water column and was represented by slime and continuous film from yellow-green to black colors. © Begell House Inc., 2016.

Connections between nesting areas of the Caspian Gull Larus cachinnans in the Northwest coast of the Azov Sea and the rest of Europe were examined by a long-term ringing program (1988-2012). The author analyzed the spatial distribution of individuals according to age (young, immature, adults) during different seasons. Directions and flight distances were determined and different types of dispersal (intra-continental, within the territory of Ukraine, within the nesting area) were specified. For perennial large nesting settlements of the Caspian gulls in the Northwest coast of the Azov Sea, the following features were determined: high degree of phylopatry in adults, the wide scope of migration after nesting and dispersion of young birds, formation of new temporary colonies by virtue of immature birds. The average movement of birds towards their colonies, during the spring was 1033 km (range 111-1900). During the post-nesting season, adult birds were found within a radius of 30 km around their colonies. In June the average displacement distance of birds of different age groups, from their colonies was 130.14 km (range 7.5-1900). In July and August, increased to 416.17 km (range 7.5-2025). In autumn, birds were found within an average distance of 284 km (range 7.5-2025) from their natal area, moving along the coast, mainly in a southwestern and western direction. They were also present in large numbers in landfills and agricultural land. Some first year birds reached the territories of Denmark, Germany, Poland and Hungary. In winter, the average displacement distance was 850 km (range 7.5-2172). The birds usually moved along the Black Sea coast of Ukraine flying to the territories of Eastern European countries. © 2015 CISO - Centro Italiano Studi Ornitologici.

There are nine alien species in the region of the study. The distribution and abundance of nonnative fish in the reservoirs of northwestern part of the Azov Sea basin depends on the scale of fishing industry activities, the degree of transformation of hydroecosystems, and the water release into the rivers from irrigation canals. There are three groups of species registered according to the number indices in the water areas of the basin. The first is the species the findings of which are rare in the region; the second group comprises fish the number of which depends on fishing industry activities; and the third one embraces the species that are high in the number and their self-reproducing populations exist. © 2015, Pleiades Publishing, Ltd.
