Marine ecosystems around Antarctica are characterised by high numbers of penguins, seals, whales, and their common prey, krill. These ecosystems are poorly understood compared to every other ocean, but are experiencing some of the most dramatic effects of climate change on earth. The project will draw on data collected by the British Antarctic Survey (BAS) and other Antarctic researchers over the past three decades to determine the environmental drivers of changing predator diets and the properties of Southern Ocean food webs that affect their stability. The proposed network-based analyses and modelling approaches are at the cutting edge of current research and will offer exciting new insights into the fate of Antarctic ecosystems in the face of global change.

南极洲周围的海洋生态系统的特点是大量的企鹅，海豹，鲸鱼和他们的共同猎物，磷虾。与其他海洋相比，人们对这些生态系统的了解很少，但它们正在经历地球上气候变化的一些最戏剧性的影响。该项目将利用英国南极调查局（BAS）和其他南极研究人员在过去三十年中收集的数据，以确定改变捕食者饮食的环境驱动因素以及影响其稳定性的南大洋食物网的特性。拟议的基于网络的分析和建模方法处于当前研究的最前沿，将为南极生态系统在全球变化中的命运提供令人兴奋的新见解。
