在陆地上，所有营养级的物种都适应了人类严重改变的环境中的空缺生态位（例如[1]）。在海洋环境中，海洋基础设施导致了人工鱼礁，导致鱼类和甲壳类动物密度局部增加[2]。海洋顶端捕食者是否表现出行为适应，以利用这样一个分散的潜在资源是未知的。使用高分辨率的GPS数据，我们展示了基础设施，包括风力涡轮机和管道，形状的运动的个人从两个海豹物种（Phoca vitulina和Halichoerus grypus）。使用状态空间模型，我们推断这些动物正在使用结构来觅食。我们强调，在海洋基础设施得到空前发展的时候，这种行为会造成生态后果。
On land, species from all trophic levels have adapted to fill vacant niches in environments heavily modified by humans (e.g. [1]). In the marine environment, ocean infrastructure has led to artificial reefs, resulting in localized increases in fish and crustacean density [2]. Whether marine apex predators exhibit behavioural adaptations to utilise such a scattered potential resource is unknown. Using high resolution GPS data we show how infrastructure, including wind turbines and pipelines, shapes the movements of individuals from two seal species (Phoca vitulina and Halichoerus grypus). Using state-space models, we infer that these animals are using structures to forage. We highlight the ecological consequences of such behaviour, at a time of unprecedented developments in marine infrastructure.
