Upper temperature effects were measured on the mean
oxygen consumption, carbon dioxide production, ingestion,
assimilation, and egestion rates of the ostracode Cypridopsis
vidua. to determine positive or negative effects of temperature stress. Oxygen consumption and carbon dioxide production were near the literature reportings of the Class Ostracoda,
with a linear increase with increasing temperatures. Respiratory Quotients were very low. Ingestion and assimilation
rates were positively linearly related with temperature to
30C and 25C. respectively, above which each was negatively
affected. Assimilation efficiency dropped from 70 percent
at 15C to 16 percent at 35C. Ingestion and assimilation rates
increased per mg biomass with decreasing size of organism.
Active avoidance of 30 and 35C temperatures was observed.
