This project aims to pair global movement with feeding ecology datasets to characterise relationships between space use and diet breadth, and tests the effects of marine industries on functional roles of marine predators. This expects to generate knowledge about population and individual specalisation using innovative biochemical approaches and shark’s unique dental anatomy. Expected outcomes include a biochemical database facilitating global collaborations, and a vulnerability scale to rank resilience to impacts based on relative specalisation. This should benefit managers by accounting for previously unknown effects of marine industries on specialists at elevated extinction risk, with limited resilience to local impacts and global change.

该项目旨在将全球运动与摄食生态数据集配对，以描述空间使用和饮食广度之间的关系，并测试海洋产业对海洋捕食者功能作用的影响。这有望利用创新的生化方法和鲨鱼独特的牙齿解剖结构来产生关于种群和个体专门化的知识。预期结果包括一个促进全球合作的生化数据库，以及一个根据相对专门化对冲击韧性进行排名的脆弱性等级。这应该会使管理人员受益，因为他们考虑到海洋工业对面临更高灭绝风险的专家以前未知的影响，这些专家对当地影响和全球变化的适应能力有限。
