Anthropogenic changes in fish assemblage of the lake Imandra
Abstract. Photochemical processes in indicator boreal plants induced by solar irradiation and their ultraviolet constitutes have been investigated in alpine environment of the Kola North. The high inducible capacity for ambient UV-B components has been found out. The UV-B promotes more rapid plant phenols accumulation at surface foliage tissue of Cucumis sativus indicator plants. The antioxidant activity of the photoinduced compounds polar extracts accumulated in indigenous coniferous species Pinus sylvestris, Picea obovata were measured with diammonium salt of 2,2`-azino-bis(3-ethylbenzthiazoline-6-sulfonate) acid. The plant antioxidant capacity has been both belt vegetation altitude and ambient irradiation degree dependent.
