A geochemical study of adult and juvenile Herpetocypris brevicaudata s
hells, calcified under laboratory conditions in? four water temperatur
es (12.4, 14.6, 19.8, 23.3 degrees C) highlighted the influence of the
calcification process on the Sr and Mg uptakes es, and showed that wa
ter temperature does not influence the Mg content in H. brevicaudata s
hells. The partition coefficients D(Sr) and D(Mg) are the first determ
inations for this species: adult: D(Sr)=0.195 +/- 0.013 and D(Mg)=0.01
71 +/- 0.0018; juvenile D(Sr)=0.198 +/- 0.009 and D(Mg)=0.0208 +/- 0.0
