摘要：

Diel feeding pattern was remarkably stable under the different food conditions and temperatures, maintaining about a 3-fold amplitude in gut contents and feeding rate over the diel period. The diel rhythm was retained even when the copepods were food limited and lost c20% body carbon during the course of the 24 h experiment. The persistence of the diel feeding rhythm in A. tonsa under starvation implies a strong selective pressure, possibly related to predator avoidance. -from Authors
