Ungulate browsing has a major impact on the composition and structure of forests. Repeatedly conducted, large-scale regeneration inventories can monitor extent pressure its impacts forest development. Based respective results, necessity wildlife management activities such as hunting, fencing, etc., be identified at landscape scale. However, have rarely been integrated into decision making. In t...

An important property of green spaces is the ability to capture dust particles from atmosphere, thereby reducing its pollution. The main organs adsorbing are leaves, therefore, in this work, dust-retaining capacity woody plants was determined by leaves. These studies relevant for selection an assortment with increased dust-holding urban areas. research work presents data on leaves following pla...

The integration of invasive species into native food webs represent multifarious dynamics of ecological and evolutionary processes. We document incorporation of Prunus serotina (black cherry) into native insect food webs. We find that P. serotina harbours a herbivore community less dense but more diverse than its native relative, P. padus (bird cherry), with similar proportions of specialists a...

Uranium (U) can be released to the environment through the entire nuclear fuel cycle. U uptake by plants is an important process for possible adverse effects in ecosystems. The soil-to-plant transfer of natural U and its distribution across plant parts were investigated in May lily (Maianthemum bifolium), narrow buckler fern (Dryopteris carthusiana), rowan (Sorbus aucuparia) and Norway spruce (...

In order to find new sources of natural antioxidants, the antioxidant potential of 70% methanolic extracts from the inflorescences and leaves of 16 species from the genus Sorbus s.s. was evaluated using two complementary in vitro test systems: the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging assay and the AAPH [2,2¢-azobis-(2-amidinopropane)dihydrochloride]-induced linoleic acid (LA)...

We established a simple HPLC method to determine the activity and stereochemistry of the chiral mandelonitrile synthesized from benzaldehyde and cyanide, and applied it to screen for hydroxynitrile lyase (HNL) activity of plant origin. A total of 163 species of plants among 74 families were examined for (R)- and (S)-HNL activities using the method. We discovered that homogenate of leaves of Bal...

Rainfall interception by vegetation plays an important role in the hydrological cycle. Next to rainfall characteristics, is influenced tree size, crown structure and bark morphology. How traits determine across functionally morphologically wide-ranging species poorly understood. We determined ratios (interception:gross precipitation) canopy storage capacities of seven temperate deciduous broadl...
