Species and generic composition of nematode communities from the epiphytic mosses in the Left-bank Polesie were studied. Nematodes were extracted by a modified Baermann’s method. A total of 47 species was found and they belonged to 34 genera, 21 families and 8 orders. The average number of nematodes was 4077 per 100 g of the moss. Rhabditida, Tylenchida, Plectida and Dorylaimida composed had more species richness (12, 10, 8 and 7 species, respectively). Species of these four orders comprised 78.7%. Representatives of three order Plectida, Dorylaimida and Monhysterida were the most numerous within the considered communities (proportion in the communities were 40.75, 21.30 and 18.65%, respectively). The majority of the identified species were subrecedent (31 or 65.95% of species composition) and accidental species (37 or 78.72%). Three species: Plectus parietinus Bastian, 1865, Mesodorylaimus bastiani Bütschli, 1873 and Geomonhystera villosa Bütschli, 1873 composed the core of nematode communities from epiphytic mosses in the Left-bank Polesie. They were found in 70.21, 57.45 and 53.19% of the samples, proportion in the community of 15.21, 10.03 and 17.96%, respectively.

The selection of cereal crops varieties as a factor in the regulation of the phytopathogenic microbiome in agrocenoses is an actual direction of the research. Cultivation of such varieties leads to a decrease in the level of biological pollution in agrocenoses and increases the quality as well as safety of agricultural products in agroecosystems. Therefore, the influence of the environmental factors (including abiotic, biotic, anthropogenic, and other) on the formation of micromycete populations in the leaf microbiome of grain crops using different plant cultivation technologies has been thoroughly studied earlier. The results of the selection the plant varieties by the indicators of influence on their population density, the frequency of the occurrence, and the intensity of the micromycete sporulation, were presented in this article. Vegetative organs of plants of the cereal crops (including the oats of Parliamentsky variety, Tembre variety, and spring barley Salomi and Sebastian varieties) were selected in the following phases: tillering, stem stage of growth, and earing. It was determined that using the traditional and organic technologies of plant cultivation in the leaf microbiome of Tembre oats and Salomi variety spring barley, the population density, the frequency of the occurrence of micromycete species, and their sporulation intensity were significantly lower compared to the plants of Parliamentsky oat and Sebastian spring barley. This shows that the cultivation of the cereal crops varieties capable of restraining the formation of micromycete on an ecologically safe level will result in a decrease in the level of biological pollution of agrocenoses and increase the biosafety of plants.

Analysis of Adjectival Formations on -schwanger The present paper is concerned with the synchronic, quantitative analysis of one aspect of adjectival word-formation. The aim of the paper is to explore the word-formation productivity of derivations ending in ‑schwanger and its frequency of occurrence in texts by taking various structure-types into consideration. I will make an attempt to identify and document the current trends in the lexis of contemporary German language by means of corpus-linguistic methods.

Im vorliegenden Beitrag werden die Ergebnisse einer synchronischen Untersuchung adjektivischer Bildungen auf -schwanger vorgelegt. In der linguistischen Fachliteratur wurde dieser Wortbildungskonstruktion wegen ihrer begrenzten Produktivität bislang kaum Aufmerksamkeit geschenkt. Auch in den bekanntesten einsprachigen Wörterbüchern sind nur wenige Bildungen mit dem Suffixoid -schwanger lemmatisiert. Den Kernpunkt der Arbeit bilden die Erkenntnisse einer Korpusuntersuchung, die mit Hilfe des Deutschen Referenzkorpus des IdS Mannheim durchgeführt wurde. Das gewonnene Belegmaterial wurde einer morphologischen, syntaktischen und semantischen Analyse unterzogen. Aspekte wie Art des Basismorphems, Fugengestaltung und Fugenvarianz kommen im Beitrag ebenfalls zum Tragen. Das Ziel der Untersuchung ist es, über die Aufdeckung struktureller Eigenschaften hinaus unter Anwendung quantitativer Methoden verlässliche Aussagen über Produktivität, Verwendungsfrequenz und Neubildungspotenz des Zweitglieds -schwanger zu machen.
