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...

Extracts from ripe fruit and seeds of Sorbus aucuparia inhibit germination of other seeds, tested with Amaranthus caudatus and Lepidium sativum. The main compound of the “neutral fraction” of fruit extracts is the lactone compound parasorbic acid (4 —7 mg/g fresh weight) which inhibits germination at concentrations > 5x1C T 4 m. The “acid fraction” contains abscisic acid (1 .3—2.5 ^ / g fresh w...

(a) Sorbose (L-sorbose, sorbinose) (C6H12O6, CAS Reg. No. 87–79–6) is an orthorhombic, bisphenoidal crystalline ketohexose. It was originally identifed in the juice of mature berries from the mountain ash (Sorbus aucuparia) where it occurs as the result of microbial oxidation of sorbitol. It also occurs naturally in other plants. Sorbose can be synthesized by the catalytic hydrogenation of gluc...

Low sequence divergence within functional alleles is predicted for the self-incompatibility locus because of strong negative frequency-dependent selection. Nevertheless, sequence variation within functional alleles is essential for current models of the evolution of new mating types. We genotyped the stylar self-incompatibility RNase of 20 Sorbus aucuparia from a population in the Pyrenees moun...
