Behavioral Basis of Flood Tide Transport by Crustacean Larvae

大多数浮游动物经历昼夜垂直迁移（DVM）， 发展的某个阶段。 常见的模式包括 日落时上升，日出时下降。 最 普遍的功能性解释是动物起来觅食 在夜间下降以避开视觉导向的捕食者 白天的 最近的研究表明， 缺乏食饵动物可以通过快速的行为改变DVM 变化 由于光线是DVM最重要的线索， 由捕食者的线索引起的迁移变化应该包括 光反应的变化。 在博士的研究目标。 调查的目的是（1）确定是否 DVM中涉及的光反应被存在或 没有视觉和非视觉导向的捕食者， (2)以确定是否存在化学、视觉和/或机械 来自捕食者的线索导致浮游动物的变化 光反应 这些研究将使一个重要的 对我们对浮游动物感官的基本理解的贡献 生物学和与捕食者的互动。

Most zooplankton undergo diel vertical migration (DVM) at some stage of development. The common pattern involves an ascent near sunset and descent near sunrise. The most pervasive functional explanations are the animals rise to feed at night and descend to avoid visually-oriented predators during the day. Recent studies indicate the presence and absence of planktivores can alter DVM through rapid behavioral changes. Since light is the most important cue for DVM, alterations in migration by cues from predators should involve changes in photoresponses. The research objectives in Dr. Forward's investigation are (1) to determine whether photoresponses involved in DVM are altered by the presence or absence of visually- and nonvisually-directed predators, and (2) to determine whether chemical, visual and/or mechanical cues from predators induce alterations in zooplankton photoresponses. These studies will make a significant contribution to our basic understanding of zooplankton sensory biology and interactions with predators.
