  3. In the summer stratified water column, the deeper the maximum depth of food distribution is, the stronger the dvm is performed ; the increase of the gradient of temperature in the thermocline layer can decrease the magnitude of the dvm and form the thermal barricade to the copepod ; the effects of the predation pressure on dvm is complex. on the one hand, the variations in the distribution depth of the predation pressure vs. the thermocline layer or the depth of the maximum food can modify the dvm patterns of the copepod. on the other hand, different predation pressure induces different dvm patterns

    在夏季分層水體中，食物的最大分佈深度越大，動物向下遷移的幅度也越大；溫躍層的溫度梯度增大可以減小動物遷移的幅度，成為橈足類垂直遷移的溫度屏障；捕食壓力對垂直遷移的影響較復雜，一方面，捕食壓力的分佈深度與溫躍層或食物峰值的相對位置的變化能夠改變橈足類垂直遷移的模式，另一方面，捕食壓力強度不同，橈足類垂直遷移的幅度也不同，捕食壓力越大，遷移的幅度越大，當捕食壓力增加到一定程度，橈足類停止向上的遷移，大部分時間呆在水體深層，可能進入捕食壓力引起的「滯育」狀態。
