Hydrobiological conditions of sapropel formation in lakes in the south of Western Siberia

详细

The results of studies of the hydrobiological regime of three sapropel lakes in Novosibirsk region in 2012 are presented. The biological production of the examined lakes, the composition and biomass of dominating species–producers of organic matter (phyto- and zooplankton, macrophytes) is determined, and the sedimentation rate of plankton and phytodetritus is estimated. The obtained results provide improved estimates of the contribution of aquatic organisms of different trophic levels to the processes of sedimentation and formation of sapropel in different types of lakes.
