Zooplankton Capture by Corals: The Effects of Water Movement under Field Conditions

从来没有一个同时研究猎物捕获成功 水流流过珊瑚礁。 本项目将调查 水运动对摄食的几个方面的影响 珊瑚生物学 该项目的第一部分将衡量 三种珊瑚，Montastrea annularis、Eusmilia fastigiata和Porites porites与猎物 通过自动泵/采样器阵列进行采样， 水流的同时测量（热敏电阻流量计， 视频），辐照度（Licor量子辐照度计）和猎物 可用性（DO泵取样器）。 膨化饲喂试验 以及在几个昼夜循环期间的收缩行为和进食。 2 mm口径的独立式水下热敏电阻流量计 空间分辨率已经构建并测试了这一点 根据LaBarbera和Vogel（1976）的设计进行的研究。 的 所收集的数据将用于描述一般流动的特征 现场状况（沿沿着深度多个点的主流流 使用Interocean S4记录海流计的断面）， 提供有关珊瑚水流环境的新资料 美国国家海洋和大气管理局国家海底研究中心的圣克鲁瓦珊瑚礁 AQUARIUS栖息地。

There has never been a concurrent study of prey capture success and water flow over reef corals. This project will investigate the effect of water movement on several aspects of the feeding biology of corals. The first portion of the project will measure field rates of feeding of three species of coral, Montastrea annularis, Eusmilia fastigiata and Porites porites with prey sampling by an automated pump/sampler array that allows concurrent measurement of water flow (thermistor flowmeter, video), irradiance (Licor quantum irradiance meter) and prey availability (DO pump sampler). Feeding experiments on expansion and contraction behavior and feeding during several diel cycles. A self-contained underwater thermistor flowmeter with a 2 mm spatial resolution has been constructed and tested for this research based on the design of LaBarbera and Vogel (1976). The data collected will be used to characterize the general flow regime at the site (mainstream flow at several points along depth transects using the Interocean S4 recording current meter), providing new information about the flow environment on coral reefs in St. Croix at the NOAA National Undersea Research Program's AQUARIUS habitat.
