海洋保护区通常用于保护生态系统免受过度捕捞等威胁。理想情况下，MPA的设计应该包括多个目标物种的移动数据，以确保足够的栖息地得到保护。我们使用了长期的声学遥测和网络分析，以确定在印度洋塞舌尔群岛的一个偏远环礁上的五种鲨鱼和一种海龟的精细尺度空间使用，并评估拟议的MPA的有效性。结果显示，在鲨鱼和海龟的强烈，物种特异性的栖息地使用，MPA使用相应的变化。从低潮时的礁滩边缘而不是高潮时的海滩（塞舌尔目前最好的）定义MPA的边界，显著增加了MPA对捕食者运动的覆盖率，平均增加了34%。根据这些结果，塞舌尔政府采用了更大的MPA，证明遥测数据如何通过直接影响政策来改善鲨鱼的空间保护。
Marine protected areas (MPAs) are commonly employed to protect ecosystems from threats like overfishing. Ideally, MPA design should incorporate movement data from multiple target species to ensure sufficient habitat is protected. We used long-term acoustic telemetry and network analysis to determine the fine-scale space use of five shark and one turtle species at a remote atoll in the Seychelles, Indian Ocean, and evaluate the efficacy of a proposed MPA. Results revealed strong, species-specific habitat use in both sharks and turtles, with corresponding variation in MPA use. Defining the MPA's boundary from the edge of the reef flat at low tide instead of the beach at high tide (the current best in Seychelles) significantly increased the MPA's coverage of predator movements by an average of 34%. Informed by these results, the larger MPA was adopted by the Seychelles government, demonstrating how telemetry data can improve shark spatial conservation by affecting policy directly.
