The lake communities showed varying degrees of accordance with long-term dynamics of global climate indices in ongoing climate warming. Inter-annual cyclic variability of phytoplankton and zooplankton was aligned, to a large extent, with the index NAO, which likewise changes in cycles. Mainly biotic interactions caused a sharp increase in biomass of macrozoobenthos in the last decades and a simultaneous sharp decline in phytoplankton biomass. The impact of global climatic factors on regional factors, i.e. water level and salinity, caused the inter-annual variability of biotic communities in the lake. We revealed statistically significant correlation between the water level of the Balkhash Lake and the long-ter...

The difference in the morphological structure of the fifth pair of legs of males A. (Acanthacartia) tonsa from the North-East of the Caspian Sea from the available descriptions is outlined. Based on an analysis of the published data and our Index saprobity S calculation, the conclusion is drawn that biological characteristics of A. (Acanthacartia) tonsa determine the ecological preferences of brackish, but not saline waters, middle oxygenated, low alkaline, and low-to middle organically enriched that confirm by bio-indication results.
