人工溪流中蜉蝣在石头上的位置随溶解氧浓度的变化而变化。在低溶解氧水平下，O2移动到电流暴露的位置，可能是为了增加呼吸交换表面的氧更新速率。在野外条件下的定位变化的预期幅度进行了测定，并表明，耗氧量的行为调节可能会共同影响栖息地分布和昼夜行为模式。这些结果漂移研究的影响进行了讨论。
Experimental investigations in a small artificial stream showed that the positioning of mayfly nymphs (Ephemeroptera) on stones varied with dissolved oxygen concentration (DO). At low DO levels nymphs moved to current-exposed positions, presumably to increase the renewal rate of oxygen at respiratory exchange surfaces. The expected magnitude of positioning changes under field conditions was determined and suggests that behavioral regulation of oxygen consumption may commonly influence both habitat distribution and diel behavioral patterns. The implications of these results to drift studies are also discussed.
