Mesophotic coral reef ecosystems (MCEs) are light-dependent benthic communities that occur deeper than shallow reefs and typically range from depths of 30 m to the bottom of the photic zone, which may extend to >150 m in some regions. MCEs represent in part an extension of shallow-water coral reef ecosystems and support a diverse assemblages of habitat-building taxa, including corals, sponges and algae, and associated fish (Reed et al., 2018). Many MCEs worldwide appear to be thriving...
Show moreMesophotic coral reef ecosystems (MCEs) are light-dependent benthic communities that occur deeper than shallow reefs and typically range from depths of 30 m to the bottom of the photic zone, which may extend to >150 m in some regions. MCEs represent in part an extension of shallow-water coral reef ecosystems and support a diverse assemblages of habitat-building taxa, including corals, sponges and algae, and associated fish (Reed et al., 2018). Many MCEs worldwide appear to be thriving compared to shallow reefs. The deep reef refugia hypothesis suggests that MCEs may be less impacted from natural and anthropogenic impacts than shallow coral reefs, and may be more stable and resilient than shallow reefs. MCEs may also act as refugia for shallow reef species through the export of fish and coral larvae. However, it is now apparent that MCEs are also vulnerable to disturbances from all facets of perturbations including climate change, bottom trawling, invasive species, and pollution. Whereas considerable data have been reported regarding the distribution, ecology, and health of Cuba’s shallow reefs, relatively little is known about the distribution, community structure and health of Cuba’s deep mesophotic reefs. Cuba’s strong marine policies and legislation has already resulted in 105 MPAs, covering nearly 25% of its insular shelf, yet overfishing, poaching, pollution and global warming are threats to these vulnerable ecosystems, as reefs worldwide are threatened.
