In a first-of-its-kind study, Florida’s critically endangered staghorn corals were surveyed to discover which ones can better withstand future heatwaves in the ocean. Insights from the study, led by scientists at Shedd Aquarium and the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, help organizations working to restore climate-resilient reefs in Florida and provide a blueprint for the success of restoration projects globally.
“While this study was performed in Florida, there is growing interest among scientists and managers in surveying heat tolerance in other coral populations around the world,” said Andrew Baker, professor in the Department of Marine Biology and Ecology at the UM Rosenstiel School, and a co-author of the study. “Our study provides a template for other efforts to identify heat-tolerant corals and comes at a time when this knowledge can help transform approaches to stem the decline of corals due to climate change. Population censuses of heat tolerance are not only useful for scientists seeking to understand how and why corals vary in their thermal tolerance, but also to managers and policy makers guiding the future of reef restoration.”
The new study, published today in the Proceedings of the Royal Society B: Biological Sciences, can help optimize the human interventions necessary to help corals survive the impacts of climate change.
The study was conducted over two research expeditions that took place in 2020, where Shedd’s research vessel, the R/V Coral Reef II, enabled a team to test the heat tolerance of 229 different strains of staghorn coral (Acropora cervicornis) that are being actively propagated by South Florida’s coral restoration programs, ranging from Broward County to the lower Florida Keys, and operated by Nova Southeastern University, Mote Marine Laboratory, the Florida Fish and Wildlife Conservation Commission, Reef Renewal, the Coral Restoration Foundation, and the University of Miami Rosenstiel School.
