Phytoplankton support 90% of aquatic food webs, and are responsible for nearly half of global primary productivity. Conversely, blooms of some phytoplankton, often associated with excess nutrients, can cause major environmental problems, including fish kills and risks to human health. However, current methods for determining the nutrient status of phytoplankton are time consuming and ignore the complexity of responses of different species in mixed populations. This project will develop new, rapid, ways of examining the nutrient condition of individual algal cells, which will be of considerable use to the water industry as well as to our understanding of aquatic ecology.

浮游植物支持90%的水生食物网，并负责近一半的全球初级生产力。相反，一些浮游植物的大量繁殖往往与营养过剩有关，可造成重大的环境问题，包括鱼类死亡和对人类健康的威胁。然而，目前用于确定浮游植物营养状态的方法是耗时的，并且忽略了混合种群中不同物种响应的复杂性。该项目将开发新的、快速的方法来检查单个藻类细胞的营养状况，这将对水工业以及我们对水生生态的理解有相当大的用处。
