Lake Chany is an inland moderately saline lake in Western Siberia. Itconsists of three lakes, Bolshye (Large) Chany, Malye (Small) Chany and Yarkul Pool. Field survey of Lake Chany was carried out at four parts of the lake with different salinity to analyze their food web structures using carbon and nitrogen stable isotope as natusral tracers. The intruding river rigion (St.1) and Malye Chany (St.2) wwkth low salinity (0.9%), the central part of Bolshye Chany (St.3) with salinity of 5.7% and the innermost part of Bolshye Chany (St.4) with the highest salinnity of 6.3% were selected as study sites. Comparison of the isotope ratios of benthis incertebrate (Chironomidae; Diptera) among the sampling sites showed the lowest δ13C and δ15N values at St.1 and highest values at St.4. The benthic invertebrates at St.3 showed similar δ13C and δ15N values to those of St.4 and St.1, respectively. Similar trends but different values of the isotope raions among the sampling stations were observed in zooplankton, POM and sediment samples, indicationg the initial substances of the food chains were different at different parts of the lake. |
