Global climate change is one of the most significant ecological challenges for the 21st Century. Phytoplankton contribute over 45% of the planet's annual net primary production and form the basis of most aquatic food chains. Conversely, some phytoplankton are toxic and cause problems in marine and fresh waters. Climate change can potentially disrupt aquatic foodchains by its impact on primary production by phytoplankton or stimulating growth of potentially toxic forms. Our project will investigate the combined impact of increasing carbon dioxide and ultraviolet light on phytoplankton and thereby help climate modellers assess the impact of climate change on aquatic ecosystems and particularly on the nation's and the world's fisheries.

全球气候变化是21世纪最重大的生态挑战之一。浮游植物贡献了地球年净初级产量的45%以上，并构成了大多数水生食物链的基础。相反，有些浮游植物是有毒的，在海洋和淡水中造成问题。气候变化可能通过影响浮游植物的初级生产或刺激潜在有毒形式的生长而潜在地破坏水生食物链。我们的项目将调查不断增加的二氧化碳和紫外线对浮游植物的综合影响，从而帮助气候建模者评估气候变化对水生生态系统的影响，特别是对国家和世界渔业的影响。
