STRATIGRAPHY OF NEOGENE DEPOSITS OF THE UKRAINIAN CARPATHIANS AND FORE-CARPATHIANS

open access: yesTectonics and Stratigraphy, 2011
The new version of the regional stratigraphical scheme of Neogene deposits of the Ukrainian Outer Carpathians and its foreland were proposed. The results of the investigation of the planktonic microfossils allows to establish ten correlative levels, which were tacen as a basis for the correlation of prodused scheme with the International Geological ...

Water exchange of the forest ecosystems epigeic bryophytes depending on changes of the structural and functional organization of their turfs and the influence of local growth environmental conditions

open access: yesБіологічні студії
Background. Moss cover plays a decisive role in increasing soil moisture in forest ecosystems. Bryophytes with high water content can significantly reduce water evaporation from the soil surface and retain it for an extended time.

Climatic, biogeographic and ecological factors influence the spatial patterns of odd‐ and even‐year dominance in biennial European butterflies and burnet moths

open access: yesEcological Entomology, EarlyView.
250,000 observations of 7 annual, 11 biennial and 4 flexible lepidoptera species in the Alps and over 150,000 observations of 5 biennial species from Scandinavia were analysed. Maps show distinct patterns of different species that fly predominantly in odd or even years in the researched areas.

Fragmented grasslands in different landscape structures provide different opportunities for cavity‐nesting Hymenoptera

open access: yesInsect Conservation and Diversity, EarlyView.
Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers
