Reef ecosystems are complex, three-dimensional marine habitats, typically structured by biogenic reef-builders such as scleractinian corals, coralline algae, or oysters, that support highly diverse, spatially structured communities of microorganisms, algae, invertebrates, and vertebrates. They are characterized by strong environmental gradients (light, nutrients, hydrodynamics), tight biogeochemical cycling of carbon, nitrogen, and phosphorus, and intricate trophic networks linking primary producers, detritivores, and higher consumers. Research on reef ecosystems focuses on processes such as calcification, bioerosion, symbiosis (e.g., coral–Symbiodiniaceae associations), connectivity among reef patches, and responses to stressors including warming, acidification, eutrophication, and overfishing, with implications for ecosystem resilience and regime shifts.
