In this paper we investigate the hypothesis that long-term sulphate (SO(4) (2-)) deposition has made peatlands a larger source of methyl mercury (MeHg) to remote boreal lakes. This was done on experimental plots at a boreal, low sedge mire where the effect of long-term addition of SO(4) (2-) on peat pore water MeHg concentrations was observed weekly throughout the snow-free portion of 1999. The...

Plants are natural sources of bioactive compounds, and the intensive use wild plants to obtain them, in particular secondary metabolites, depletes biocenoses. Instead, modern biotechnological methods, especially cell tissue culture vitro, make it possible get environmentally friendly, highly productive plant raw materials that able synthesize accumulate specialized substances, which valuable fo...

High-valued medicinal plants Achillea millefolium, Acorus calamus, Arnebia nobilis, Fumaria indica, Gymnema sylvestre, Origanum vulgare, Paeonia emodi, Peganum harmala, Psoralea corylifolia, Rauwolfia serpentina, and Vetiveria zizanioides were identified with the help of taxonomical markers and investigated for characterization and palynological studies. These parameters are used to analyze the...

Heinrich Wilhelm Schott (1794–1865) was one of the pioneering researchers in taxonomy species-rich monocot family Araceae. He described numerous new plant species various genera, including Acorus, which is currently segregated as a monogeneric and order occupying position sister to rest monocots. While describing his mostly used characters that are considered low, if any, taxonomic value. His d...
