Mean d1880c. of replicates from 15 individuals (instars 6 and 7) is 4.60% for the winter 19921993 (15~~0, = 9.5%0) and 4.68% for the winter 19931994 (6permil*OL = 9.50, Table 1). Actual d180c. in both seasons is enriched compared to the isotopic composition of a theoretical calcite formed isotopic equilibrium ( d180eq). The difference is +2.3 2 O.l%o to a 6permil80, calculated using the fractionation factors given by Friedman and OpermilNeil ( 1977) and exactly matches the vital offsets for adults and juveniles of these species found during a oneyear calibration study in Ammersee and Starnberger See, which will be presented and discussed elsewhere.
