多年来，病毒已被证明是广泛的浮游植物物种的死亡因子，包括棕囊藻属（Prymnesiophyceae）内的物种。由于其多态性的生活史，其全球性的分布，以及几种棕囊藻物种形成密集水华的能力，该属是我们理解元素地球化学循环的关键角色。本文概述了迄今为止所知道的关于病毒在调节棕囊藻种群动态中的生态作用。它探讨了哪些变量影响藻类宿主-病毒的相互作用，并探讨了病毒诱导的细胞裂解的棕囊藻的功能和结构的远洋食物网以及有机碳和营养物质的流动的影响。
Over the years, viruses have been shown to be mortality agents for a wide range of phytoplankton species, including species within the genus Phaeocystis (Prymnesiophyceae). With its polymorphic life cycle, its worldwide distribution, and the capacity of several of the Phaeocystis species to form dense blooms, this genus is a key player for our understanding of biogeochemical cycling of elements. This paper provides an overview of what is know to date about the ecological role of viruses in regulating Phaeocystis population dynamics. It explores which variables affect the algal host-virus interactions, and examines the impact of virally induced cell lysis of Phaeocystis on the function and structure of the pelagic food web as well as on the flow of organic carbon and nutrients.
