Thistle and Eckman Despite its conceptual importance, predation as an organizing force in deep-sea communities is essentially unstudied. Although a variety of species are known to be predators in the deep sea, the large, motile epifauna are the focus of this study because they should be important predators and some species appear to be susceptible to experimental manipulations with cages. The research consists of two parts. The present proposal requests support to investigate cage performance in the deep sea. With the knowledge gained, we will propose a follow-up investigation of predator effects by conducting experiments sufficiency free of cage. The results of these investigations should be widely applicable because large, motile epifauna occur in most deep-sea communities.

Thistle 和 Eckman 尽管捕食在概念上很重要，但它作为深海群落中的一种组织力量基本上还没有被研究过。 尽管已知多种物种是深海的捕食者，但大型、活动的表层动物群是本研究的重点，因为它们应该是重要的捕食者，并且某些物种似乎容易受到笼子实验操作的影响。 该研究由两部分组成。 目前的提案请求支持调查深海网箱的性能。 凭借所获得的知识，我们将提出通过进行充分的无笼实验来对捕食者效应进行后续研究。 这些调查的结果应该广泛适用，因为大多数深海群落中都存在大型、活动的表层动物群。
