The results of the 30-years-old local fitoсenotic monitoring, conducted on the contact of forest and subalpine belts in Chornogora (Ukrainian Carpathians) are expounded. Researches are conducted with the use of large-scale map of ground-transect by an area 24 hectares on a north-western slope Pozhizhevska within the limits of heights 1300-1500 м. It is set that because of introduction of the protected mode, there is a process of renewal of primary vegetation and increase of high boundary of the forest on this territory. Directions, basic stages and mechanisms of the demutation changing, are certain.

On the example of 16 species it is shown that factors of interaction between the neighboring species, microclimate and own phytogenous field play important role in the viability of small populations. The characters of population structure and dynamics are revealed with regard to the interaction between species. It was established, that the role of the interaction between plants is more significant for small populations in comparison with large ones.

The ways of soil nematods biodiversity within secondary forest ecosystems were enlighted. The attention is directed to probability for using the bioindication peculiarities of the Nematoda communities for estimation of the sanitary status of the forest. There are discussed the means for using the natural antagonistic organisms of Nematoda in the aim to rising the stability of wood cultures and decreasing impact of the phytohelminta on agrocultures.

The results of different long-term researches of acclimatization features of species distributed in gardening of cities are given. The morphological and anatomic, physical and chemical, metabolic adaptive reactions of phenotypic on acclimatization conditions are shown. The outecological bases of optimization of decorative assortment for cultivation in a green zone of urban and industrial territories are offered. As one of ways of maintenance of stability and functionality of the city planting it is recommended to increase their specific and form variety.

The features of ecology of representatives of family of Sphaeriidae are studied and their specific composition in reservoirs is certain Lvіv which makes 9 kinds. It is set that influencing of terms of external environment is caused by the uneven distributing of shellfishes in reservoirs. The most favorable terms for them were folded in permanent gidrotops.

The anthropogenic load influence on integration of microbial cenosis in the rhizosphere of a winter wheat is considered. Define of correlations connections of main ecological-trophic groups of rhizosphere microorganisms show that more stable microbial cenosis form by cultivation of a winter wheat in crop rotation with use of organic manure and organic-mineral fertilizers.

The state of lowland populations of Symphytum cordatum Waldst. et Kit. ex Willd occuring in isolated localities in the Western Ukraine is studied. On the example of four populations restricted to different habitat conditions the role of ecological factors determining population viability is analyzed. The necessity of protection of S. сordatum at the edge of its range is emphasized that could provide conservation of the regional biodiversity and genic pool of the species.

Analysis of stages and trends of investigation of higher aquatic flora and vegetation of East Galychyna was made. Four stages were separated. Character of research by these stages were detected. Systematic, geobotanical, ecological directions of investigation and direction of resourses research of this vegetation type on the territory of East Galychyna were established as well as analysed them.

Nine species of the genus Chrysotoxum from the western region of Ukraine have been recorded. Most of them (Ch. bicinctum (L.) Ch. cautum (Harr.) Ch. elegans Loew, Ch. fasciolatum (De Geer) Ch. octomaculatum (Curtis, 1837)) у регіоні притаманні гігро- і мезофітним біотопам, декілька видів (Ch. fasciatum (Müller, 1764), Ch. verralli (Collin, 1940)) occure both in hygro- and mesophytic and in xerophytic biotopes.

The structure of species of Planorbinae in the main river basins of Ukraine is established: the Danube – 16 species, the Dniester – 17, the Southern Bug – 20, the Western Bug – 21, the Dneper – 23, the Siversky Donets – 18, the rivers of the Crimea – 7 species. It is established, that 15 species Planorbinae are widespread, 7 species were found to be associated with certain basins, 3 species are rare.

Genus Plecotus is presented in the fauna of region by two sibling species, P. auritus and P. austriacus, which form wide sympatry zone in the western provinces of Ukraine. By craniometrical characters (23 characters were investigated), the species are much closed and have average distance by Mayr’s coefficient of divergence CD=2.42, and by Hutchinsonian ratio HR=1.076. Maximal displacements of species in both indices are concerning just four characters: length of auditory bulla Bul (CD=4,60, HR=1.16), length of upper toothrow CM3 (CD=4.10, HR=1.12), and lower toothrow im3 (CD=4.04, HR=1.12). All the data abundantly evidence of earlier stages of species differentiation in characters, which clearly related with trophism as well as hunting activity in a whole. Exceeding of critical values take place just in one (first among mentioned) character, that suggest considerable similarity of species in ecological preferences.
