Grassland biodiversity is vulnerable to land use change. How to best manage semi-natural grasslands for maintaining biodiversity is still unclear in many cases because land-use processes may depend on environmental conditions and the indirect effects of land-use on biodiversity mediated by altered abiotic and biotic factors are rarely considered. H...

Grassland biodiversity is among the most vulnerable to land use. How to best manage semi-natural grasslands for maintaining biodiversity is still unclear in many cases because processes may depend on environmental conditions and indirect effects are rarely considered. Here we evaluate the relative importance of direct and indirect effects of grazin...

Polarizing microscopy and scanning electron microscopy were used to determine the distribution, size, shape, and chemical composition of Fe–Mn nodules in Albeluvisols (Retisols) from south-western Ukraine and the relationship of these pedological features with redox processes. Intrusive, impregnative, and depletion features were observed. The highe...

The scientific literature dedicated to the analysis of peculiarities of the soils colouring and interconnection the genetic horizons colour as well as separate morphological elements with their properties have been analyzed. The identification of colour of genetic horizons in 20 profiles of brownish-podzolic gleyed soils of Ukrainian and Polish Pre...

Based on the analysis of literature data, the genesis, distribution, morphology, composition and properties of Fe-Mn pedofeatures (mainly nodules and concretions), taking into account their unique geochemical role, review of general scientific information was done. Terminology and classification problems concerning pedofeatures of this type were sh...

The aim of this research was to identify variations of the morphogenetic features of thePrecarpathias brownish-podzolic soils (Albeluvisols) depending on the biogeocenosis type. The morphology of the 20 soil profiles in the Precarpathians in Ukraine and the Carpathian Foothills in Poland was analyzed. Factors and conditions for the formation of the...

Problems of actual designation of illuvial genetic horizons in Ukrainian soil science were analyzed. It was found that the current system does not reflect all the subtleties of illuvial horizon and it is not in accordance with the current trends in international soil science. On the basis of the brown-podzolic gleyed soils of the Precarpathians, wh...

Cutans occurring in Albeluvisols of the Precarpathians in the Ukraine were studied. The morphology of the cutans and their components were described. The obtained results show that the studied cutans are composed mainly of colloidal clay. Clay cutans in the studied soils are characterized by smooth surface, microlamination, and clear optical orient...

Luvisols and Albeluvisols prevail within the Carpathian Foothills in Poland and the Precarpathians in the Ukraine. Genesis of the soils is related to translocation of colloids (i.e. clay minerals and iron oxides) from upper part of the soil profile to the lower horizons (so-called lessivage). Higher bulk density and lower total porosity of the illu...

Soil algae of Ciscarpathia brownish-podzolic soils of different ecosystems have been studied. Species composition, systematic structure, algae ecological spectra and their ecobiomorph structure have been established. It has been found out in total 104 algae species, including. It has been established the lack of blue-green algae and decreasing of d...

Вивчали ґрунтові водорості бурувато-підзолистих ґрунтів Передкарпаття різних екосистем. Встановлено видовий склад, систематичну структуру, екологічні спектри синьо- зелених водоростей. Виявлено 17 видів синьо-зелених водоростей з 1 класу, 2 порядків, 4 родин, 5 родів. Серед екобіоморф найбільш чисельні Р- та Cf-форми The soil algae of brown-podz...

Проаналізовано видовий склад, систематичну структуру альгофлори хвойних лісів України. Наведено результати досліджень альгоугруповань хвойних лісів Передкарпаття та Степової зони України, виділені їх специфічні риси. Ключові слова: грунтові водорості, альгоугруповання, хвойний ліс. The species composition, taxonomic algae of coniferous forests of...

The species composition, taxonomic algae of coniferous forests of Ukraine was analysed. The results of investigation of algogroupping coniferous forests of Ciscarpathia and Steppe of Ukraine, their peculiar features was determined.

The microbocenoses of brownish-podzolic gleied soils of Ciscarpathia is investigated. The high in-tensity of processes of release and accumulation of aluminium regardless of depth is established. It is proved that in investigated soils mobilization of aluminium can be accessory under the influence of microflora which is able to dissolve Al-phosphat...
