Abstract
Cultures of the freshwater ostracod Herpetocypris brevicaudata were kept under laboratory conditions in order to study effects of water temperature on development time and calcification process. Four culture temperatures were used: 22.4, 14.6, 19.8 and 23.3 degrees C. H. brevicaudata cultured at 19.8 and 23.3 degrees C showed higher survival rate and faster development than those cultured at 12.4 and 14.6 degrees C. Water temperature also has a clear influence on the degree of calcification of the ostracod shells. For H. brevicaudata, the 15-19 degrees C temperature range constitutes a threshold below which Ca content of valves significantly decreases. Time required to calcify is also longer below this threshold. The increase of the calcification time due to lower water temperatures seems to induce low survival rates.
