The diel vertical migration of zooplankton was irrelevant to the phytoplankton density.
浮游植物密度与浮游动物的昼夜垂直移动关系不密切。

Two thermal environments, one with and the other without thermal gradients, were designed to study diel variation in body temperature (Tb) .
设计具有和缺乏温度梯度两种热环境，研究幼龟体温昼夜变化和体温调节。

The research results show that the size distribution, diel change, daily variation have a good connection with relative humidity and Richardson number.
