Low-molecular-weight metabolites of aquatic macrophytes growing on the territory of Russia and their role in hydroecosystems

This article deals with the issues of studying low-molecular-weight volatile organic compounds (VOCs) of aquatic macrophytes growing in Russia under different environmental conditions and geographic regions. It is shown that the composition of VOCs and their content depend on the abiotic (geographical location of habitats, hydrological regime, and light conditions) and biotic factors (season and vegetation phase, distribution in different vegetative organs). Special attention has been paid to the functions performed by VOCs in aquatic ecosystems and their possible use for controlling phytoplankton development and algal “blooms” in inland water bodies.
