Viral Dynamics in the Sea

本研究项目的总体目标是获得海洋病毒衰变速率的准确定量数据，并全面了解海洋环境中病毒衰变的机制。这项研究的一部分将研究由太阳辐射引起的病毒衰变、附着在颗粒上、微鞭毛虫的放牧和细菌降解。这项研究将试图区分病毒传染性的衰减率和病毒颗粒的消失。该研究还将对来自几个科的海洋病毒进行研究，以便更好地将“病毒循环”纳入地球化学循环。这些结果将产生重要的发现，有助于从概念上理解是什么控制了海洋环境中的病毒动力学，并为各种海洋环境的去除率和负责从海洋中去除病毒感染性和颗粒的因素提供定量数据。

PROJECT ABSTRACT The overall objective of this research project is to obtain accurate and quantitative data on decay rates of marine viruses and a comprehensive understanding of the mechanisms responsible for viral decay in the marine environment. Part of this study will investigate viral decay caused by solar radiation, attachment to particles, grazing by microflagellates, and bacteria degradation. The study will attempt to distinguish between decay rates of viral infectivity and the disappearance of viral particles. The study will also undertake of marine viruses from several families in order to better incorporate the "viral loop" into geochemical cycling. The results should yield important findings toward a conceptual understanding of what controls viral dynamics in the marine environment, and provide quantitative data for a variety of marine environments on removal rates and the factors responsible for the removal of viral infectivity and particles in from the sea.
