Marine food webs, which include many economically and ecologically important species, ultimately depend on energy generated by primary producers such as seaweeds (macroalgae). Algae are particularly unique as they metabolize omega-3 and omega-6 long-chain (C20) polyunsaturated fatty acids (LC-PUFA), which play essential physiological roles both in the algae themselves and in the animals that consume them. The abiotic conditions in the environment strongly impact the levels and composition of fatty acids in macroalgae. The expected climatic changes including increased temperature and levels of dissolved CO2 in the future ocean are projected to lead to a decline in essential LC-PUFA in macroalgae with flow-on effects to higher trophic levels. This project aims to deliver the first assessment of the impacts of ocean warming and ocean acidification on production and trophic transfer of the key health-benefitting LC-PUFA, in a laboratory based coastal model community.

海洋食物网包括许多经济和生态上重要的物种，最终依赖于初级生产者产生的能源，如海藻(大型藻类)。藻类特别独特，因为它们代谢omega-3和omega-6长链(C20)多不饱和脂肪酸(LC-PUFA)，这两种脂肪酸在藻类本身和食用它们的动物中都发挥着重要的生理作用。环境中的非生物条件对大型藻类的脂肪酸水平和组成有很大的影响。预期的气候变化，包括未来海洋中温度的升高和溶解二氧化碳的水平，预计将导致大型藻类中必要的LC-PUFA含量下降，并向更高的营养水平流动。该项目旨在对海洋变暖和海洋酸化对主要有益健康的LC-PUFA的生产和营养转移的影响进行首次评估，这是在以实验室为基础的沿海模式社区进行的。
