动物迁移 meaning in Chinese
animal migration
animal movement
Examples
- I freely admit the former existence of many islands, now buried beneath the sea, which may have served as halting places for plants and for many animals during their migration .
我直率地承认，从前曾存在过许多岛屿可作为植物和许多动物迁移中歇足之地，现在都已埋在海下了。 - 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
在夏季分层水体中，食物的最大分布深度越大，动物向下迁移的幅度也越大；温跃层的温度梯度增大可以减小动物迁移的幅度，成为桡足类垂直迁移的温度屏障；捕食压力对垂直迁移的影响较复杂，一方面，捕食压力的分布深度与温跃层或食物峰值的相对位置的变化能够改变桡足类垂直迁移的模式，另一方面，捕食压力强度不同，桡足类垂直迁移的幅度也不同，捕食压力越大，迁移的幅度越大，当捕食压力增加到一定程度，桡足类停止向上的迁移，大部分时间呆在水体深层，可能进入捕食压力引起的“滞育”状态。
