The dynamics of the water budget of Orog Nuur and Taatsiin Tsagaan Nuur fluctuating lakes in the Valley of the Lakes (Western Mongolia) in the period 2010–2018 is studied. It is shown that Orog Nuur Lake has passed to the wet phase in its long-term cycle, while Taatsiin Tsagaan Nuur Lake is currently in a transitional phase, which in previous cycle...

... showed a more objective picture of the distribution of macroinverte­ brates in various lake biotopes. The total abundance of Spinicaudata in shallow waters was 11.5±5.7 spe­ cimens/m 3 , in uncharted areas of great depths -2.5±1.9 specimens/m 3 , reed thickets -15.2±5.4 speci­ mens/m 3 . The distribution of nekton biomass in 2014 is shown in Fig. ...

... is due to too intensive warming of water (up to 29.6 °C) at shallow depths, which causes macroinvertebrates to concentrate in the least heated biotopes, in particular, reed thickets, which also provide additional microbi­ otopes to avoid predators and food resources in the Prokin, A.A. et al., 2019.

Analysis of quantitative charac­ teristics for all biotopes showed a significant positive dependence of the number of nekton species in Taat­ siin Tsagaan Nuur Lake from the electrical conductivi­ ty of water (b = 0.0004, p = 0.002, R 2 = 0.7) and acidity (b = 8.97, p = 0.033, R 2 = 0.36). ...

Surveys on benthic macroinvertebrate communities of ten standing water bodies (Bezbog, Kalin, Choklyovo marsh, Bistraka, Dospat, Stoykovtsi, Drenov dol, Pchelina, Dolna Dikanya, Dyakovo) were conducted in the period July-August 2018. They were chosen to represent natural (lakes) characterized with reference conditions as well as artificial and heav...
