浮游动物和游泳动物的昼夜垂直迁移（DVM）是由选择性优势驱动的，即在白天避开水面附近的视觉线索捕食者。就像有第二组捕食者占据了迁徙者黑暗的白天深处一样，在迁徙过程中也有一组不同的捕食者构成了一系列威胁。在这里，我们从迁徙者的角度来研究这些迁徙，列举他们所面临的掠夺性威胁，并评估各种捕食者类型的威胁潜力。这项研究的基础是对加州蒙特雷湾中层群落进行的数千小时的实地观察和测量，主要是通过遥控潜水器进行的。我们提供了一些捕食者/猎物的相互作用的帐户，我们介绍了一种方法来计算特定的捕食者的威胁潜力，MBARI的长期时间序列的定量视频调查的基础上。
Diel vertical migrations (DVM) by zooplankton and nekton are driven by the selective advantage of avoiding visually cued predators near the surface during the hours of daylight. And just as there is a second set of predators that occupy the migrators’ dark daytime depths, there is also a diverse suite of predators that comprise a gauntlet of threats during the migrations. Here we examine these migrations from the perspective of the migrators, to enumerate the kinds of predatory threats they face and to assess the threat potential of various predator types. The study is based on thousands of hours of in situ observations and measurements of the mesopelagic community in Monterey Bay, California, conducted chiefly by remotely operated vehicles (ROVs). We provide accounts of some predator/prey interactions, and we introduce a means to calculate the threat potential of specific predators, based on MBARI’s long-term time-series of quantitative video surveys.
