Effects of temperature on the oxygen consumption and heart rate in the inter-tidal wedge clam, donaxfaba (Gmelin)‎

Abstract EN

The effect of temperature ،on the rate of oxygen consumption and heart rate has been investigated in the Red Sea, inter-tidal wedge clam Donax faba.

The Q10 values for both oxygen consumption and heart rate were often <2.5 and were relatively constant over a wide range of temper-ature.

This suggest that wedge clam is well adapted for life in high temper-ature environment.

It was noted, however, that behavioural mechanisms were important in reducing the degree of temperature stress that could be experienced in the field.
