Hydrobiologic Survey of Some Lakes of Mountain Range Ergaki (West Sayan)
Three alpine lakes (Oiskoe, Karovoe, Raduzhnoe) of mountain range Ergaki were sampled in 11- 15 September 2008. Species (taxonomic) composition, number of species, abundance and biomass of phytoplankton and zooplankton, phytobenthos and zoobenthos of each lake were studied for the first time. Coeffi...
