Protection Gaps Threaten Alacranes Reef in Gulf of Mexico

A study published in Marine Ecology Progress Series warns that the Alacranes Reef, a key marine reserve in the southern Gulf of Mexico, has significant gaps in its protected‑area network. Researchers evaluated 111 sites using censuses, seafloor data and satellite imagery and found that many ecologically important habitats—such as seagrass meadows and coral patches—lie outside strict protection, leaving them exposed to climate change, fishing and other human pressures. The authors, Ángela Randazzo‑Eisemann, Erick Barrera‑Falcón and Joaquín Rodrigo Garza‑Pérez, argue that the reef’s resilience depends on a mosaic of interconnected habitats, not just the most coral‑rich zones, and recommend expanding marine‑protected‑area criteria to include these vulnerable zones to preserve ecosystem functions and coastal community benefits.

The findings highlight the need for updated conservation strategies to safeguard the reef’s biodiversity and the services it provides to surrounding populations.
