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.

Warming Waters Disrupt Caribbean King Crab Larvae Behavior
Caribbean king crab larvae swim less and die more at 32°C, a near threefold jump in mortality over the control group. The shift is quiet but consequential: first-stage larvae reverse their vertical swimming, sinking faster rather than rising. That behavioral flip threatens dispersal and larval supply for outplanted populations. For restoration programs, this is a warning that stocking reefs with *Maguimithrax spinosissimus* assumes a resilience the larvae may not have.
Florida Keys Reef Accretion Diminished by Repeated Bleaching Events
The Florida Keys' reef-accretion potential has fallen from 1.65 millimeters per year in 1996 to net erosion following the 2023 bleaching event, with four thermal-stress episodes driving over 75 percent of the total decline. The 1997-1998 event alone accounted for roughly half of that loss, largely through the collapse of *Acropora palmata*. This is not a distant threat; it is a measurable, documented trajectory.
