Millennium of Cold-Water Coral Habitat Loss in East Pacific Linked to Low ENSO Variability
A new study published in the Proceedings of the National Academy of Sciences reveals significant historical insights into cold-water coral ecosystems in the East Equatorial Pacific. Despite their current status as thriving ecosystem engineers, the long-term history and climate sensitivity of these corals have remained poorly understood. Researchers compiled over 900 coral ages from the Galápagos region to reconstruct their population dynamics during the mid- to late Holocene. The findings document a millennium-long period of habitat loss coinciding with intervals of low El Niño-Southern Oscillation (ENSO) variability. This research highlights the critical dependence of cold-water coral habitats on specific climate conditions, particularly ENSO patterns. By establishing a clear link between reduced ENSO variability and coral decline, the study provides essential context for understanding how future climate changes might impact these vital marine ecosystems. The results underscore the vulnerability of cold-water corals to shifts in oceanographic conditions, offering valuable data for conservation efforts and climate modeling in the Pacific region.
