Validated hawksbill stocks reveal a hidden reef sentinel in the Florida Keys

Seventy-six hawksbill turtles hand-captured across a decade of shallow-reef surveys in the Florida Keys National Marine Sanctuary tell a clear story: these waters are critical nursery grounds for a highly imperiled species. Mixed-stock DNA analyses reveal a shifting population, with Mexican rookery dominance waning and diversity increasing. The sanctuary's shallow reefs serve as essential entry points for post-oceanic hawksbills.
