    Abstract

    Marine reserves are important tools for managing exploited populations yet increasing evidence suggests most reserves arc too small to benefit mobile sharks. Characterising the habitat requirements of juvenile sharks within the broader species' distribution can thus inform effective reserve design. Methods included baited remote videography, acoustic telemetry, stable isotopes sand productive modelling. Large-scale conservation planning to protect distinct elasmobranch assemblages Will benefit from abiotic surrogates, while effective MPA placement to protect quality habitats for juvenile sharks will require species- rather than aggregate-level predictions Small-scale MPAs will benefit species or life-stages with restricted movements and dependency on coastal producers. Multi-scale and species-focused inquiry is imperative for effective conservation of these declining predators.
