Dynamics of zooplankton in the saline lakes of the South-Eastern Zabaikalia in the different climatic periods

The results of the long-term studies are presented, they concern with the zooplankton of saline lakes located in Torey depression in the Southeast of the Zabaikalsky krai. The species diversity of zooplankton is mostly composed of euryhaline and widespread species. Halophyles and euryhaline species form a structure forming complex. The qualitative and quantitative indicators of zooplankton are characterized by a high variability. The unstable hydrologic and hydrochemical conditions are the main factors affecting the composition and development of the zooplankton.
