Impacts of environmental change on the structure and stability of Antarctic food webs

南极洲周围的海洋生态系统以大量的企鹅、海豹、鲸鱼和它们的常见猎物磷虾为特征。与其他海洋相比，人们对这些生态系统知之甚少，但它们正经历着地球上气候变化带来的一些最剧烈的影响。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，以确定影响捕食者饮食变化的环境驱动因素，以及影响其稳定性的南大洋食物网的特性。提出的基于网络的分析和建模方法是当前研究的前沿，将为面对全球变化的南极生态系统的命运提供令人兴奋的新见解。

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.
