Abstract

The quality of the aquatic environment in Altai Mountain lakes located in the territories of SPNAs of different categories is investigated. Using 12 metrics and biotic indices based on macrozoobenthos indicators (total biomass; number of species; Shannon species diversity indices; oligochaete; chironomid; D/Nex; %NCh + O; Ephemeroptera, Plecoptera, and Trichoptera (EPT); Ephemeroptera, Trichoptera, and Odonata (ETO); Multimetric Macroinvertebrate Index Flanders (MMIF); Biological Monitoring Working Party Index (BMWP); and the Average Score Per Taxon Index (ASPT)), the water quality of seven Altai lakes is assessed: Verkhnee Multinskoe, Poperechnoe, Aya, Koksha, Svetloe, Kolyvanskoe, and Beloe. Five lakes can be used as reference lakes for water bodies of this type. The multimetric BMWP and MMIF indices show similar results in most of the studied lakes, correlated with each other and with other benthic community metrics. The analysis of their relationship with hydrochemical and physical parameters of the environment allow us to identify the main indicators determining the ecological state of the water bodies. The positive influence of water salinity or components determining it are noted; moreover, the values of bioindication indices are related to the content of oxygen and nutrients.
