Vegetation recovery in severely disturbed alpine ecosystems can be accelerated through active restoration measures. This study evaluated the short-term effects of two treatments, planting propagated native Salix (willow) shrubs three different densities (1, 2.5, and 4 plants/m2) seeding grass Festuca ovina (sheep fescue), a heathland. We natural vegetation (i.e. cover, vascular plant species ri...

variability in morphological traits, phenolic content, and antioxidant activity of 15 populations of iranian ferula species collected from natural habitats in different regions of iran were investigated. total phenolic content (tpc) of fruit extracts varied from 12.77 to 120.72 mg tannic acid per 1g dry weight. total flavonoid of fruits extract varied from 5.45 mg quercetin per 1 g dry weight i...

To test the hypothesis that the cytochrome pathway is not invariably saturated when the alternative pathway is engaged, we titrated root respiration of several species with KCN (an inhibitor of the cytochrome pathway), both in the absence and presence of an inhibitor of the alternative pathway (salicylhydroxamic acid, SHAM). The slopes of the resultant KCN [rho] plots ([rho]cyt) were then used ...
