Structural and production characteristics of aquatic plants the waste channel of the Izhevsk thermal power station-1 (the Udmurt Republic)

On an example of four characteristic (modelling) species of communities Lemno-Typhetum angustifoliae, Typheto angustifoliae-Phragmitetum autsralis and Lemno minori-Spirodeletum influence of the warmed-up waters of the Izhevsk thermal power station-1 (Izhevsk, Udmurtia) on production-powered and anatomic-morphological characteristics of aquatic macrophytes are presented. The biomass increase, acceleration of seasonal development, change of structural parameters of vegetative bodies and inflorescences of hydrophytes and helophytes is revealed.
