Short Rotation Forestry and Earthworm Diversity: Impacts and Responses
… and reproduction. The native Alnus glutinosa, Betula pendula and Fraxinus excelsior litter supported earthworms and their activities over non-native Acer pseudoplatanus, Castaneas sativa and Eucalyptus nitens. Native British earthworms indicated a significant preference (p < 0.05) for E. nitens …

On-line screening of bioactive compounds and application of comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry for the analysis of birch bark
… for chemical composition of birch bark (Betula pendula). The exploitation of the mass spectra and retention index information allowed the identification of more than 600 organic compounds. Altogether, 59 phenolic compounds were identified in the inner layer of birch bark. To the best of …

QUERIES IN QUERCUS: FROM THE DEVELOPMENT OF A TISSUE CULTURE CLONAL PROPAGATION SYSTEM TO THE EVALUATION OF STRESS TOLERANT HYBRID WHITE OAKS FOR THE URBAN ENVIRONMENT
… points of two tree species (Quercus bicolor and Betula pendula) grown under well-watered and drought conditions in limited soil volume. In response to soil water deficit conditions, Q. bicolor reduced its turgor loss point (osmotic adjustment) and maintained gas exchange rates. In contrast, B. …

Wood extractives in hemicellulose stabilized emulsions
Norway spruce (Picea abies) and silver birch (Betula pendula) are widely spread in Europe. They are important raw materials for sawmill, pulp mill and paper industry. This industry utilizes merely 30-40% of the wood in the form of cellulose. Hemicelluloses, mainly galactoglucomannans (GGM) in …

Acidification and eutrophication of forests on sandy soil: effects of forest type and deposition load
… plantations into mixed species forests with Betula pendula and Quercus robur certainly diminishes the input of potentially acidifying and N deposition and consequently soil acidification and nitrate seepage to groundwater. But it should be emphasized that also in some of the observed …

Phytoremediation: a tool for restoring land degraded due to opencast coal mining
… potential of Alnus glutinosa (Alder), Betula pendula (Roth) (Birch) and Larix decidua (Larch), which are commonly used in UK land reclamation, to sequester metals: Zn, Cd, Mn, Pb and Cu, from mine spoils. This study also compares the abilities of newly planted trees to sequester metals …
