Habitat suitability models of elkhorn coral provide ecological insight to support coral reef restoration
Coral reefs are experiencing unprecedented levels of stress from global warming, ocean acidification, fishing, and water pollution. In the Caribbean and Western Atlantic, multiple stressors have resulted in widespread losses of the dominant reef‐building Acroporid corals, two of which are listed as...

Coral reefs are experiencing unprecedented levels of stress from global warming, ocean acidification, fishing, and water pollution.
