Abstract: Coral reef declines, particularly in coastal zones, have been linked to temperature stress and anthropogenic impacts on water quality. St. Lucie Reef near Stuart, Florida, USA receives increased estuarine efflux as a result of watershed changes and management policies that have substantially altered historic natural flows. This research examines the direct effects of estuarine discharge water and thermal stress on corals, and supplements existing in-situ monitoring on St. Lucie Reef with ex-situ factorial experimental design. Ambient and elevated temperatures (25°C and 30°C) and offshore water versus estuary discharge water collected from the St. Lucie Inlet were used to investigate the individual and interactive effects on Montastraea cavernosa, one of two dominant scleractinian species at St. Lucie Reef. Coral stress gene expression, zooxanthellae density, and chlorophyll concentration were evaluated to determine effects on the corals and their symbionts. Collaborative partnerships with the Florida Fish and Wildlife Commission, Florida Department of Environmental Protection, and the St. Lucie Inlet Preserve State Park facilitate data sharing to inform decision making for South Florida’s resource management strategies. Creating effective resource management is crucial for the conservation of coastal ecosystems impacted by land-based sources of pollution both locally and globally. Summary: Individual and combined effects of estuarine discharge water and thermal stress on Montastraea cavernosa are examined using an ex-situ factorial experimental design.Report abuse »
