The Lake Chany complex, located in western Siberia, Russia, consists of large shallow inland lakes with the salinity gradient from an estuary part to the most inner part. The food web from phytoplankton and aquatic plants to predatory fish in the Lake Chany was characterized by spatial changes in environmental factors and primary producers. The bird spices were considered to be not only highest consumer, but also the effective member for the nitrogen environments and vegetations near their colonies. Furthermore, the NOAA satellite images were thought to be valid for environmental monitoring in Siberia.
