Diversity and Distributions (2018)

Summary: This research investigates the effectiveness of marine protected area (MPA)
networks in safeguarding highly mobile shark and ray species. By integrating satellite
telemetry data with MPA coverage and fishing pressure, the authors show that existing MPAs
provide limited protection due to the mismatch between predator home ranges and reserve
boundaries. The study advocates for expansion and realignment of MPAs to reflect ecological
connectivity and recommends a network-based approach to conservation planning that
considers both biological needs and transboundary governance challenges.
