      notes: "When the lake was open (i.e., lake level was high and water was lost by outflow), the 18O/16O ratio of lakewater was low and rela- tively constant because the isotopic composition was controlled mainly by the 􏰆18O of input waters. When the basin was closed (i.e., lake level was low and water was lost predominantly by evaporation), the lakewater was isotopically enriched in 18O due to preferential evaporative loss of 16O. At low stage, the lake was not only isotopically enriched in 18O, but the isotopic composition of the lake was more variable because of the high sensitivity of a small lake volume to changes in the ratio of evaporation to pre- cipitation."

      sampling method: For stable isotope analysis, each 1 cm subsample was disaggregated by soaking in 3% H2O2 and subsequently sieved at 250 mm. The .250 mm fraction was collected on filter paper, dried at 60�C and transferred to glass scintillation vials. Ostracods and gastropods were separated from the matrix using a dissecting microscope at 10 � magnification. Adult specimens of the ostracod Cytheridella boldi were picked from the sieved 425?500 mm fraction, Heterocypris communis were picked from the 351?500 mm fraction, and Cypria obtusa were picked from the 250?300 mm fraction. Specimens of the gastropod Pyrgophorus sp. were separated from the sieved .1000 mm fraction. Ostracod valves were cleaned of organic material using 15% H2O2, then washed in deionized water, rinsed in methanol, and dried. Gastropods were cleaned in the same manner, except that specimens were cleaned further by sonication. Samples consisting of many monospecific ostracod carapaces (|15 C. boldi, |20 H. communis, |25 C. obtusa) were loaded into a stainless-steel carrying boat, crushed with a glass rod dipped in methanol and allowed to dry overnight. Numerous monospecific ostracod valves were used to constitute a sample to reduce variance that might result from running single, short-lived individuals whose isotopic signatures might reflect short-term (i.e., seasonal) water-column temperature and salinity conditions (Heaton et al., 1995)

instrument: VG Isocarb preparation system. Isotopic ratios of purified CO2 gas were measured on-line by a triple-collector VG Prism Series II mass spectrometer

measurement material: ostracod
measurement material detail: Heterocypris communis
measurement standard: PDB
notes: "When the lake was open (i.e., lake level was high and water was lost by outflow), the 18O/16O ratio of lakewater was low and rela- tively constant because the isotopic composition was controlled mainly by the 􏰆18O of input waters. When the basin was closed (i.e., lake level was low and water was lost predominantly by evaporation), the lakewater was isotopically enriched in 18O due to preferential evaporative loss of 16O. At low stage, the lake was not only isotopically enriched in 18O, but the isotopic composition of the lake was more variable because of the high sensitivity of a small lake volume to changes in the ratio of evaporation to pre- cipitation."

sampling method: For stable isotope analysis, each 1 cm subsample was disaggregated by soaking in 3% H2O2 and subsequently sieved at 250 mm. The .250 mm fraction was collected on filter paper, dried at 60�C and transferred to glass scintillation vials. Ostracods and gastropods were separated from the matrix using a dissecting microscope at 10 � magnification. Adult specimens of the ostracod Cytheridella boldi were picked from the sieved 425?500 mm fraction, Heterocypris communis were picked from the 351?500 mm fraction, and Cypria obtusa were picked from the 250?300 mm fraction. Specimens of the gastropod Pyrgophorus sp. were separated from the sieved .1000 mm fraction. Ostracod valves were cleaned of organic material using 15% H2O2, then washed in deionized water, rinsed in methanol, and dried. Gastropods were cleaned in the same manner, except that specimens were cleaned further by sonication. Samples consisting of many monospecific ostracod carapaces (|15 C. boldi, |20 H. communis, |25 C. obtusa) were loaded into a stainless-steel carrying boat, crushed with a glass rod dipped in methanol and allowed to dry overnight. Numerous monospecific ostracod valves were used to constitute a sample to reduce variance that might result from running single, short-lived individuals whose isotopic signatures might reflect short-term (i.e., seasonal) water-column temperature and salinity conditions (Heaton et al., 1995)
