The Ecology of Coral Reefs:
By Doug McCauley Awards: Giese, Myers, Miller
Coral reefs are highly diverse and valuable marine ecosystems that are under threat worldwide from myriad stressors. Providing for the future health of coral reefs and the people that depend on these reefs in a changing world requires accurately addressing the complex problems that face these systems.
In our research we study the ecology of coral reefs, the biology of key coral reef animals, and interactions between humans and reefs. All of this takes place in the remote central Pacific, primarily at Palmyra and Tabuaeran Atolls. Because coral reefs provide the literal foundation of atoll ecosystems and atoll societies, ensuring their long-term health in these settings is critical.
Large reef animals are preferentially harvested from reefs, and thus have severely declined across the globe. A considerable nmuber of these these large animals perform key functions in coral reef ecosystems. For this reason, we invest much effort in studying the ecology of these large animals resident in the areas we work. Past subjects of our research include grey reef sharks, bumphead parrotfish, and manta rays. Reef sharks are top predators that may exert important top down controls on reef communities. Bumphead parrotfish are the world’s largest parrotfish and consume literally tons of reef material every year. Manta rays are key players in planktonic communities and and the mainstay of many reef ecotourism operations.
The diversity of coral reefs and the complexity of the threats that face them necessitate that that we combine efforts with multiple collaborators in order to address these issues. Our group uses tools from the fields of ecology, biogeochemistry, and anthropology to answer questions about reef ecology and reef health.
