The process of ecological orientation (ecologization) of the exposition and scientific and educational activities of natural history museums is analyzed. The process at issue is connected with constantly increasing attention of people to the environment, especially to the problem of preserving biological and landscape variety.

A scheme of the regional phytogeographical division of the Carpathian Mts. is proposed. It is based upon regional division of the Carpatian parts of the territory of six Carpathian countries.According to the scheme compiled, flora of the Carpathians belongs to the Carpathian Subprovince of the Central-European Floristic Province and only small part of it – to the Pannonian Floristic Province. Five Sectors – West, East, South-Carpathians, Apuseni and Transsilvanian plateau, 27 Districts, 119 regions and 14 subregions have been distinguished within the Carpathian Subprovince. Flora of the Pannonian part belongs to one district which includes 7 regions.

Possible forming of a new ecologic-geographycal seven-petal race is revealed due to the results of the investigation of variation of the number of petals of Anemone nemorosa L. (Ranunculaceae) in different phytocoenotical conditions (in Lviv region). Absence of the influence of anthropogenic pressure on morphological parametres of petals is ascertained, its measure of variation and plastic is determined.

At present 393 species of Collembola belonging to 106 genera and 13 families have been recorded. The biggest quantity of species is presented in the families Isotomidae (86 species), Onychiuridae (63 species) and Sminthuridae (61 species). The maximum species richness was found in the collembolan fauna of the Ukrainian Carpathians due to high variety of edaphotops and mountain springtail species. The species richness of regional faunas of springtails in Roztochia and Western Podillya is also considerable and is characterized by a great number of springtail species typical of the meadow-steppe, steppe and anthropogenic biotopes.

The investigations of structure and functional conditions of the natural and anthropogenic soil covering in "Gutsulshchyna" NNP have been initiated. Morphological, morphometric and water-physical characteristics of dominated soils were studied. The peculiarities of the formation of burozem in various geomorphological and hydro-vegetative conditions of natural and anthropogenic environment were established. A scheme for the investigation of soil covering on the protected territories based on the ecological and functional approaches was designed.

The investigations were carried out since 1997 till 2000 during the nesting periods in three experimental areas in the Upper Dnister basin, viz. in 50 villages (255-310 m alt.) in the Upper Dnister lowland, in 17 - in the Upper Dnister Beskydy (650-750 m alt.) and in 17 - in the Skolivski Beskydy (1100-1300 m alt.). 56 bird species were recorded in the villages of the Upper Dnister basin with general density of population amounting to 300,1 pair/km2 . The population structure includes 33 species where House Sparrow dominates and Swallow – subdominates. In comparison with natural biotopes, the avifauna of villages is greatly affected by the anthropogenic factor which favours the fact that synanthropic species nest only there. They are House Sparrow, Swallow, House Martin, Swift, Jackdaw, Black Redstart, Rock-Dove, White Stork. Phytocenotic conditions considerably influence the life of birds in villages, where vegetation sharply differs from that of the surrounding biotopes and that fact highly affects the structure and abundance of avifauna. Both the structure and the quantity of avifauna depend on the altitude of a settlement situation. With growing altitude the species diversity of birds decreases (55, 54, 45 species) and their abundance increases (292,3; 387,3; 401,6 pair/km2 ). The diversity decreases due to the plain inhabitants which have their vertical distribution limit within the study area, those are White Storc, Syrian Woodpecker, Garden Warbler, Marsh Warbler, Thrush Nightingale, Rook.

The paper deals with the specific composition and peculiarities of the bionomics of groupings of freshwater mollusks in Lviv region. The results of malakological researches have shown the existence of 25 species of freshwater molluscks. Astatic biotopes are the optimum conditions for existence of mollusk populations at the insignificant level of anthropogenous influence. Strengthening the anthropopressure creates the best conditions for invasion and development of populations in constant reservoirs.

The expedition materials of soil studies within the floodplain areas of the Transcarpathia are presented. 14 soil profiles are described in detail. They are characterized by 4 natural soil types and their anthropogenic analogies. The present studies are the first stage of a complex research aimed at understanding the structure, properties and functions of the Transcarpathian floodplain soil types.
